Letter from the Executive Chairman

Dear Fellow Shareholders,
Ero Copper had another strong year 
in 2019, highlighted by significant 
year over year copper production 
growth while maintaining first-
quartile operating costs at $0.93 
per pound of copper produced. In 
addition, we continued to execute 
our strategy of investing in our 
copper operations to unlock the 
vast exploration potential of the 
Curaçá Valley.
Building upon the success of 2018, our 
performance in 2019 is a direct reflection of our 
world-class operating asset base combined with 
our exceptional operational teams in Brazil. The 
commitment to excellence and operational 
improvement demonstrated by our colleagues 
in Brazil allows us to execute our growth 
strategy.

At our MCSA operations, we achieved record 
throughput, copper grades and metallurgical 
recoveries in 2019. This resulted in record 
annual copper production, a significant 39% 
year-on-year increase.

At our NX Gold operations, we announced an 
initial three-year mine life extension in late 
2019 that will serve as a solid foundation of 
gold production on which to build longer-term 
growth through exploration success. We 
successfully commenced mining of the San 
Antonio vein, which we expect to provide the 
foundation for the NX Gold Mine for years to 
come.

In 2019, we strengthened our Board of 
Directors with the appointment of Dr. Sally Eyre 
and Chantal Gosselin. These appointments 

added significant capital markets, financial and 
mining experience that complement the 
existing skillset of our Board of Directors.

We believe that a strong commitment to 
sustainability is central to our social license to 
operate. The investments we are making within 
our mining operations and within our local 
communities continue to support the long-term 
growth of the region. We are committed to 
responsible mining and believe that transparent 
reporting is imperative to the sustainability of 
our business. In recognition of this, we will be 
issuing our first sustainability report outlining 
this performance during the first half of 2020. 

I would like to take this opportunity to thank all 
of our stakeholders for their continued support 
and, in particular, the many employees and 
contractors of the Company and each of the 
communities in which we operate.

I look forward to building on our success in 
2020.

Letter from the President & CEO

Dear Shareholders,
2019 proved to be another great 
year for the Company with 
continued operational execution, 
improved financial stability and 
significant growth of our 
exploration programs during the 
year. I am confident the best is yet 
to come as we continue to grow 
our business. 

Solid Performance in 2019

Safety Performance

Ero Copper achieved strong operating and 
financial results in 2019, exceeding copper 
production guidance and achieving C1 cash 
costs well below guidance. 

Following the successful construction and 
commissioning of the Vermelhos mine in 2018, 
our operational team at MCSA carried positive 
momentum into 2019, delivering 39% year-on-
year copper production growth. 

Our net earnings attributable to the owners of 
the Company was $91.9 million, or $1.01 per 
diluted share, in 2019 compared to ($3.2) 
million, or ($0.04) per in 2018. Cash and cash-
equivalents at year-end totaled approximately 
$21.5 million and we ended the year with $30 
million in undrawn revolving credit facilities. We 
are well positioned to execute on our strategy 
despite weakness in the spot copper price.

Additionally, our BRL per tonne mined key-
performance indicators (“KPIs”) during the year 
showed significant year-on-year improvement 
in both underground and open pit mining 
operations while processing and indirect KPIs 
remained in-line. 

The health and safety of our employees and 
contractors is paramount to our business. We 
remain committed to improving the safety at 
each of our operations to ensure our team 
members can perform their roles safely and 
effectively.

We had a lost time injury frequency rate 
(“LTIFR”) of 0.99 in 2019, up from a record low 
of 0.32 in 2018 but down from 1.47 in 2017. We 
remain focused on continuous improvement 
and achieving our goal of zero lost time injuries.

Creating Value Through Exploration

We believe the exploration potential of the 
Curaçá Valley is immense and unlocking that 
value for our key stakeholders continues to be a 
core focus. 

In 2019, we drilled approximately 235 km in the 
Curaçá Valley, with 26 drill rigs operating, we 
had one of the largest exploration programs 
globally. Approximately 23% of the drilling was 
focused on regional greenfield exploration and 
we expect this to increase to approximately 
60% in 2020.

ERO COPPER | 2019 ANNUAL REPORT | 5

Our aggressive and exploration program in 
2019 led to the significant discoveries of 
Baraúna and Siriema as well as a new “Super 
Pod” within the Deepening Extension of the 
Pilar Mine. Baraúna, located at the Pilar Mine, is 
immediately below the southern portion of the 
historic open pit. This combined with a new 
high-grade zone of mineralization in the 
Deepening Extension increases our confidence 
that we will continue to extend the mine life at 
Pilar well into the future. The Siriema discovery 
is located approximately 1.5 km south of the 
Vermelhos Mine and was the first target to be 
drilled following our regional targeting work. 
Siriema validates our data-driven exploration 
methodology and we look forward to testing 
our more than 140 regional exploration targets 
in the years ahead. It is also worth mentioning 
the discovery at Siriema included a zone of 
brecciated massive sulphide containing 
significant nickel, cobalt and platinum group 
metals, further highlighting the potential value 
of the Curaçá Valley as a major magmatic 
sulphide district.

Beyond new discoveries, our 2019 drilling  
programs contributed to a greater than 100% 
increase in mineral reserves at the MCSA 
mining complex and more than a 400% increase 
in mineral resources at the NX Gold Mine.

Outlook for 2020

I look forward to another positive year in 2020 
with continued strong operational 
performance, completion of the HIG mill 
installation, commissioning of the recently 
installed ore sorting plant, and the execution of 
our 2020 exploration program.

In the year ahead, we will continue to build on 
the achievements of 2019 to unlock new value 
for our shareholders.

2019 Highlights 

2019 Operational Highlights 

Another record year of copper production 

• 

Increased  year-on-year  copper  production  by  39.1%,  with  42,318  tonnes  of  copper  produced  in 
concentrate compared to 30,426 tonnes produced in 2018.   

•  Exceeded the Company’s 2019 original guidance of 37,000 tonnes of copper by 14.3%. 
•  C1 cash cost of $0.93 per pound of copper produced for 2019, $0.07 below the low-end of the Company’s 

2019 guidance range of $1.00 to $1.10 per pound of copper produced. 

•  Total  of  approximately  2.4  million  tonnes  of  ore  grading  1.93%  copper  processed  during  the  year 
producing 42,318 tonnes of copper in concentrate after average metallurgical recoveries of 90.5%. 
•  Advanced several key capital programs in 2019 including completion of approximately 235,000 meters of 
drilling, acceleration of development at Pilar and Vermelhos Mines to enhance operational flexibility and 
production volumes, commencement of civil works and infrastructure installation for the Company’s high-
intensity grinding mill which is expected to be commissioned during Q2 2020, and installation of a 200,000 
tonne per annum ore sorting plant that was commissioned in Q1 2020. 

•  Total  annual  gold  and  silver  production  at  the  NX  Gold  operations  of  30,434  ounces  gold  and  19,641 

ounces silver at C1 cash costs of $691 per ounce of gold produced. 

2019 Financial Highlights 

Cash position, liquidity and available lines of credit: Total cash and cash equivalents and available liquidity at 
December 31, 2019 was $21.5 million and $25.1 million compared to $18.9 million and $4.7 million, respectively, 
at the end of 2018.  Increased liquidity is due to a reduction in the Company’s working capital deficit from $9.3 
million at the end of 2018 to $4.9 million at the end of 2019, as well as an increase in the Company’s credit facilities 
during the year. As at the end of 2019, the Company had $14.0 million undrawn on its secured, revolving credit 
facility in Canada, plus an additional R$64.8 million in available undrawn lines of credit in Brazil. 

Revenue: The Company increased year-on-year revenues from its copper operations at MCSA by 33.3%, totalling 
$246.2 million in 2019 compared to $184.7 million in 2018.  The increase in revenue was attributed to the increase 
in year-on-year copper production. 

Year-on-year decline in gold revenue from the Company’s gold operations at NX Gold was a result of decreased 
production volumes as we transition into the Santo Antonio vein, partially offset by increased gold prices, resulting 
in a net decrease in gold revenue of 20.1% totalling $38.6 million in 2019 compared to $48.4 million in 2018. 

Mine gross profit: The Company significantly increased year-on-year mine gross profit from its copper operations 
at MCSA totaling $105.6 million in 2019 compared to $66.1 million in 2018.  The increase in mine gross profit was 
primarily driven by increased revenues from increased copper production, and a decrease in cash costs over the 
prior  year  as  a  result  of  higher  grades  processed  and  improved  metallurgical  recoveries.    The  Company  also 
recognized mine gross profit of $11.4 million in 2019 compared to $16.1 million in 2018 from its gold operations 
at NX Gold as a result of lower gold production volumes.   

Net  income:  The  Company  recognized  net  income  of  $92.5  million  (net  income  per  share  of  $1.08)  in  2019 
compared to a net loss of $3.0 million in 2018 (loss per share of $0.04), attributable to increased mine gross profit, 
a recovery related to value added taxes previously paid on sales in Brazil, and the recognition of available tax 
losses and tax credits in MCSA.   

During the year, the Company recognized a recovery of $21.6 million in net income related to value added taxes 
previously paid on sales in Brazil.  The recovery was recognized as a result of a Brazil Supreme Court ruling in 2017 
that concluded that the relevant taxing authorities had historically used an incorrect methodology to determine 
such  taxes.    The  ruling  set  a  precedent  for  all  companies  in  Brazil  but  was  required  to  be  confirmed  for  the 
Company’s specific claim, for which approval was received in July 2019.  These credits can be used to offset a 
variety of other taxes, including income taxes and taxes on future sales.

In  addition,  the  Company  recognized  a  $28.3  million  net  deferred  tax  recovery  primarily  resulting  from  the 
recognition of available tax losses and tax credits in MCSA.  At December 31, 2019, the Company considered the 
taxable income generated since acquisition of MCSA and forecasted future taxable income and determined that 
it was now considered probable that the benefit of these losses and tax credits in MCSA would be realized. 

Q4 2019 Highlights 

Q4 Operational Highlights 

Continued Strong Performance at MCSA Operations  

•  589,065 tonnes processed grading 2.16% copper producing 11,526 tonnes of copper in concentrate after 

metallurgical recoveries that averaged 90.7% during the period. 

•  C1 cash cost of $0.80 per pound of copper produced during Q4 2019, a $0.21 per pound improvement 
over the third quarter, resulting in full-year 2019 C1 cash costs of $0.93 per pound of copper produced. 

Exploration focus turns to regional greenfield targets in 2020 

•  One  of  the  most  comprehensive  exploration  programs  underway  globally  with  26  drill  rigs  operating 

within the Curaçá Valley plus an additional four drill rigs operating at the NX Gold Mine. 

•  Prior  to  the  end  of  the  quarter,  the  Company  released  its  fourth  quarter  exploration  results  outlining 
continued  success  within  the  Curaçá  Valley  including  two  new  regional  discoveries  at  N1  South  and 
Vermelhos  North,  the  identification  of  the  “Keel  Zone”  -  a  nickel-platinum-group  metals  rich  zone  at 
Siriema in the Vermelhos District, plus the most significant set of holes drilled to date in the Deepening 
Extension of the Pilar Mine. 

•  Within the Vermelhos District, where 12 drill rigs are currently operating, the identification of a brecciated 
massive  sulphide  zone  within  the  Siriema  deposit  containing  copper,  nickel,  cobalt  and  platinum, 
palladium,  rhodium  and  gold  (“3PGE+Au”)  was  released.  Results  were  highlighted  by  hole  FSI-40  that 
intersected  9.1  meters  grading  2.66%  copper,  1.74%  nickel,  0.07%  cobalt  and  1.46  grams  per  tonne 
3PGE+Au  including  5.6  meters  grading  3.37%  copper,  2.59%  nickel,  0.10%  cobalt,  and  2.08  grams  per 
tonne 3PGE+Au. The zone remains open at depth and has been delineated over approximately 150 meters 
in strike length, 105 meters down plunge and over an average thickness of 10 meters. The results of the 
multi-element analysis at Siriema represents the first evidence in the history of the Curaçá Valley of a 
consistent  zone  of  elevated  nickel  and  platinum-group  metals  (“PGMs”).  Work  continues  to  test  the 
extension of the zone to depth and to the north is planned in 2020. 
In the Pilar District, where 11 drill rigs are currently operating, drilling in the Deepening Extension zone 
continues to significantly extend the known extent of high-grade copper mineralization at the mine both 
with respect to thickness and grade. The latest results are indicative of the emergence of a new high-
grade  mineralized  chamber,  or  “Superpod”,  highlighted  by  hole  FC5616  that  intersected  51.8  meters 
grading 3.49% copper including 33.4 meters grading 4.96% copper and hole FC5615 that intersected 62.5 
meters  grading  1.65%  copper  including  26.1  meters  grading  2.37%  copper.  These  results  are 
complemented by previously announced intercepts FC47142 that intersected 34.7 meters grading 2.29% 
copper including 18.6 meters grading 3.15% copper and hole FC47139 that intersected 7.1 meters grading 
6.50% copper including 4.1 meters grading 9.01% copper, both located on section 47, approximately 400 
meters south of the new intercepts on section 56 (as referenced in the Company’s press release dated 
September 12, 2019). 

• 

•  Three drill rigs are currently operating on regional exploration targets within the Surubim District.

Q4 NX Gold Operational Highlights 

•  Q4 2019 gold and silver production at the Company’s high-grade NX Gold Mine of 6,043 ounces of gold 
and 4,315 ounces of silver, a 39% improvement over the third quarter as first ore from the Santo Antonio 
vein was mined and processed. 

•  43,207 tonnes grading 6.32 grams per tonne gold processed during the period, producing 6,043 ounces 

of gold after metallurgical recoveries that averaged 68.9% during Q4 2019. 

•  Fourth quarter C1 cash cost of $980 per ounce of gold produced, resulting in full year 2019 C1 cash costs 

of $691 per ounce of gold produced. 

•  The Company expects production to stabilize throughout 2020 as production reaches planned capacity 

from the Santo Antonio vein.  

•  An updated NI 43-101 (as defined herein) compliant mineral resource and mineral reserve estimate, and 
associated mine  plan,  was  announced  in the fourth quarter of 2019, outlining an updated, high-grade 
mineral reserve demonstrating a production profile averaging 40,500 oz per year over an initial three-year 
mine life. 

•  Four  drill  rigs  are  currently  operating  at  the  NX  Gold  Mine  and  exploration  efforts  are  focused  on 
conversion of the inferred portions of the Santo Antonio vein discovery and extensions of the Brás vein 
aimed at further increasing the life-of-mine.  

Q4 Financial Highlights 

Revenue: Revenues from the Company’s copper operations at MCSA decreased by 6.4% from $72.3 million in Q4 
2018 to $67.7 million in Q4 2019.  The decrease in revenue was attributed to the decrease in copper production. 

Revenues from the Company’s gold operations at NX Gold decreased 37.1% from $12.8 million in Q4 2018 to $8.0 
million  in  Q4  2019.  The  decline  was  primarily  a  result  of  decreased  production  volumes,  partially  offset  by 
increased gold prices. 

Mine gross profit: Mine gross profit from the Company’s copper operations at MCSA totaled $30.4 million in Q4 
2019 compared to $33.9 million in Q4 2018.  The decrease in mine gross profit was primarily driven by decreased 
revenues from decreased copper production, partially offset by a decrease in cash costs over the comparative 
period  as  a  result  of  higher  grades  processed  and  improved  metallurgical  recoveries.    The  Company  also 
recognized  mine  gross  profit  of  $0.6  million  in  Q4  2019  compared  to  $0.6  million  in  Q4  2018  from  its  gold 
operations at NX Gold.   

Net income: The Company recognized net income of $45.4 million (net income per share of $0.53) in Q4 2019 
compared to a net income of $11.3 million in Q4 2018 (net income per share of $0.13), primarily attributable the 
recognition of available tax losses and tax credits in MCSA.   

During Q4 2019, the Company recognized a $27.4 million net deferred tax recovery primarily resulting from the 
recognition of available tax losses and tax credits in MCSA.  At December 31, 2019, the Company considered the 
taxable income generated since acquisition of MCSA and forecasted future taxable income and determined that 
it was now considered probable that the benefit of these losses and tax credits in MCSA would be realized.

MCSA operations continued to perform well during the fourth quarter, with a significant increase in both tonnes 
and grade mined from Pilar. During the quarter, 433,258 tonnes of ore were mined grading 1.73% copper, a 19% 
increase in tonnes mined, and a 15% increase  in grade over the prior  quarter (362,667 tonnes mined grading 
1.51% copper during third quarter). At Vermelhos, production volumes were in-line with the prior quarter with 
185,045 tonnes mined. Average grades mined at Vermelhos declined slightly to 3.39% copper due to normal stope 
sequencing. Increases in tonnage and grade mined from the Pilar mine resulted in a significant improvement in 
total contained copper, with a total of 618,303 tonnes mined grading 2.22% copper during the period. For the full 
year 2019, a total of approximately 2.46 million tonnes grading 1.98% copper was mined.  

At the Company’s milling operations, 589,065 tonnes of ore grading 2.16% copper was processed during Q4 2019. 
Metallurgical recoveries averaged 90.7% during the period, resulting in average full-year 2019 recovery of 90.5%, 
an improvement over the Company’s guidance of 90.0%. During 2019, a total of 2.42 million tonnes of ore was 
processed  grading  1.93%  copper,  resulting  in  the  production  of  42,318  tonnes  of  copper  in  concentrate.  The 
benefit  of  several  low-cost  milling  and  flotation  improvement  initiatives  undertaken  at  the  end  of  2018  have 
continued  to  support  strong  metallurgical  performance  in  2019.  Going  forward,  improved  metallurgical 
performance remains a key focus area of the Company, complimented by the high-intensity regrind mill project, 
currently underway. 

The Company’s regrind mill project, sanctioned during the first quarter of 2019, remains on-budget and on-track 
for  equipment  delivery  during  the  first  quarter  of  2020  with  commissioning  and  ramp-up  during  the  second 
quarter of 2020. A significant improvement in overall metallurgical recoveries of 3% to 4% and plant performance 
beyond those already realized are expected once the new mill is operational. 

In addition to the regrind mill project, the Company completed delivery of a 200,000 tonne per annum ore sorting 
plant at the end of 2019. Construction of associated infrastructure was completed in the fourth quarter of 2019, 
and commissioning occurred during first quarter 2020, subsequent to the end of the year. The Company aims to 
test a variety of ore sources and grades from different deposits throughout the Curaçá Valley over the course of 
the first half of 2020 with the aim of better evaluating the potential of pre-concentration.  The ore sorting project 
represents an investment in longer-term potential value optimization for deposits within the Company’s current 
portfolio.   

C1 cash cost averaged $0.80 and $0.93 per pound of copper produced, respectively, during the three and twelve-
month period ended December 31, 2019.  C1 cash costs during the fourth quarter reflect the increase in contained 

ERO COPPER | 2019 ANNUAL REPORT | 13 

 
 
 
 
 
 
 
copper produced driven by mill head-grades, resulting in a $0.21 decrease in C1 cash costs compared to third 
quarter. As a result of the Company’s increased production, and favorable prevailing foreign exchange rates, C1 
cash costs for the full year came in $0.07 below the low end of the Company’s guidance of $1.00-$1.10 per pound 
of copper produced. 

Subsequent to the end of the quarter, the Company announced its production, cash cost, and capital guidance for 
2020.  The  Company  provided  annual  copper  production  guidance  of  41,000  to  43,000  tonnes  of  copper  in 
concentrate at C1 cash costs between $0.85 and $0.95 per pound of copper produced. Capital cost guidance for 
2020 is $74 million, with an additional $28 million to fund the 2020 exploration program through the end of Q3 
2020. The program is designed to complete approximately 172,000 meters of drilling through the end of Q3 2020, 
an annualized run rate of approximately 230,000 meters of drilling. By year end, the Company expects that 60% 
of  total  drilling  will  be  allocated  to  testing  new  greenfield  targets  identified  through  the  Company’s  airborne 
geophysical survey and ongoing data analysis. 

In support of its strategy to drive organic growth of the Company through exploration and new project delivery, 
Ero will continue to run one of the most comprehensive drill programs globally throughout 2020. With 26 drill rigs 
currently operating, the Company remains focused on using a data driven approach to exploration. This program 
has already resulted in several new discoveries since 2016 including two new discoveries announced in the fourth 
quarter at N1 South and Vermelhos North, as well as the identification of a nickel-PGM rich zone at Siriema. 

In the Vermelhos District, approximately 80 kilometers to the north of the Caraíba Mill complex, which includes 
the  high-grade  operating  Vermelhos  Mine,  exploration  continues  to  focus  on  continued  testing  of  high-value 
exploration targets surrounding the Vermelhos Mine. Systematic testing of targets along the previously identified 
10-kilometer trend of soil and induced polarization (“IP”) anomalies along the Paredao Antiform (known as the 
“Vermelhos System”) is ongoing, with the most recent discoveries of N1 South and Vermelhos North representing 
the current known southern and northern extent of the Vermelhos System, respectively.  

In-mine exploration in the Vermelhos District also continues to deliver results as new mineralization was identified 
beneath the Toboggan and Sombrero orebodies with the most significant intercept returning 6.4 meters at 5.03% 
copper, as well as in the East Zone, where drilling in the deep portion of the East Zone returned 8.4 meters grading 
4.02% copper at a depth of approximately 450 meters below surface. In-mine exploration at Vermelhos in 2020 
will continue to test targets beneath the known extent of mineralization in the main orebody, as well the vertical 
extent of the East Zone. 

In addition to in-mine exploration, drilling within the broader Vermelhos System remains focused on advancing 
the Siriema and N8/N9 deposits. Drilling at Siriema in the fourth quarter was focused on testing high priority areas 
within  the  “keel  zone”,  a  high-grade  zone  of  brecciated massive  sulphide  containing  copper-nickel  and  PGMs, 
identified  through  down-hole  electromagnetic  (“EM”)  surveys.  Results  were  highlighted  by  hole  FSI-40  which 
intersected 9.1 meters grading 2.66% copper, 1.74% nickel, 0.07% cobalt and 1.46 grams per tonne 3PGE+Au. 
Drilling at N8/N9 during the period was focused on testing the extent of known mineralization, as well as the high-
grade zones within each orebody. The planned 2020 exploration program will continue to delineate the extent of 
the “keel zone” at Siriema and the extent of the N8/N9 orebodies. 

During the fourth quarter, the Company re-prioritized drilling of the Deepening Extension where a new set of deep 
drill holes, drilled down plunge to the north have intersected thick and high-grade mineralization indicative of a 
newly identified mineralized chamber, or “Superpod”, in the Deepening. In addition, drilling of the Baraúna and 
South Extension zones continued to confirm extensions of mineralization within these zones. 
Drilling in the Deepening Extension is currently targeting mineralization on the East Limb of the Pilar Mine between 
level  -725 and  level  -1300  approximately  1,200 meters  to 1,750 meters below surface and approximately 100 
meters laterally from the current level of the primary ramp (completed to level -925). Underground drilling during 
the  period  continued  work  that  commenced  in  mid-2019  to  re-prioritize  testing  of  the  known  extent  of 
mineralization within the zone, including down-plunge exploration drilling beneath the deepest known extents of 

ERO COPPER | 2019 ANNUAL REPORT | 14 

 
 
 
 
 
 
 
mineralization within the Pilar Mine. The results during the fourth quarter are among the most significant holes 
on a grade-meter basis drilled by the Company in the Pilar Mine since acquisition of the Vale do Curaçá Property 
in 2016. Results were highlighted by hole FC5616 that intersected 51.8 meters grading 3.49% copper including 
33.4 meters grading 4.96% copper and hole FC5615 that intersected 62.5 meters grading 1.65% copper including 
26.1 meters grading 2.37% copper. These results are complemented by the previously announced intercepts of 
FC47142 that intersected 34.7 meters grading 2.29% copper including 18.6 meters grading 3.15% copper and hole 
FC47139  that  intersected  7.1  meters  grading  6.50%  copper  including  4.1  meters  grading  9.01%  copper,  both 
located on section 47, approximately 400 meters south of the new intercepts on section 56. Exploration results 
from the Deepening Extension continue to support the belief that the Pilar Mine is open at depth, where high-
grade mineralization continues to be encountered approximately 350 meters below the deepest level of current 
development  at  the  mine.  Currently,  five  drill  rigs  are  positioned  to  drill  the  Deepening,  targeting  resource 
conversion and testing the extent of the mineralization to the North, South, and at depth. 

Elsewhere  within  the  Pilar  underground  mine,  drilling  at  Baraúna  was  performed  from  surface  targeting 
mineralization beneath the southern portion of the open pit mine and extensions of mineralization to the south. 
Results were highlighted by hole FC1923 that intersected 31.8 meters grading 0.83% copper including 7.0 meters 
grading 1.31% copper immediately beneath the south pit wall and FC0901 that intersected 4.5 meters grading 
0.44% copper from 19.6 meters down hole, approximately 200 meters south of the known limit of mineralization 
within the Pilar  Mine.  While  results to date in this area are low-grade disseminated  mineralization, additional 
geophysical  work  is  ongoing  to  better  refine  high-grade  targeting  in  this  zone.  Drilling  in  the  South  Extension 
continued to confirm the continuity of the orebody to the south, and current drilling is testing the extent of this 
zone at depth and to the South.

The fourth quarter at the NX Gold Mine was a continuation of transitioning mining activity to the Santo Antonio 
vein.  During  the  period,  remaining  exposed  ore  blocks  continued  to  be  mined  from  the  Brás  vein,  while 
development and mining activities ramped up within Santo Antonio. As a result of first production from the Santo 
Antonio vein, ore production and grade were 20% and 30% improved versus the third quarter, respectively. During 
the fourth quarter, 43,207 tonnes of ore grading 6.32 grams per tonne of gold was processed, producing 6,043 
ounces  of  gold  and  4,315  ounces  of  silver  as  by-product  after  metallurgical  recoveries  that  averaged  68.9%. 
Recoveries  during  the  quarter  were  adversely  impacted  due  to  the  transition  of  ore  feed  from  Brás  to  Santo 
Antonio. Recoveries are expected to improve in the first quarter and throughout 2020. C1 cash costs averaged 
$980 per ounce of gold produced. For the full year, the NX Gold Mine produced 30,434 ounces of gold at C1 cash 
costs of $691 per ounce. 

In the fourth quarter, the Company released its National Instrument 43-101, Standards of Disclosure for Mineral 
Projects  (“NI  43-101”)  compliant  Mineral  Resource  and  Mineral  Reserve  estimate  outlining  a  significantly 
improved Mineral Reserve extending mine-life by three years and demonstrating average annual production of 
40,500 ounces of gold. Subsequent to the end of the quarter, the Company released 2020 production, cash cost, 
and capital expenditure guidance for the NX Gold Mine. The Company expects to produce 38,000 to 40,000 ounces 
of gold at C1 cash costs of $475 to $575 per ounce. Capital costs are expected to be $6.0 million, plus an additional 
$3.5 million allocated to exploration for 2020. 

Following the release of the NI 43-101 compliant Mineral Resource and Mineral Reserve estimate and mine plan 
in the fourth quarter, the exploration focus at NX Gold has shifted to infill drilling of the inferred portions of the 
Santo  Antonio  orebody  with  the  focus  of  converting  additional  mineralization  into  measured  and  indicated 
mineral  resources.  The  regional  exploration  program  continues  to  work  to  identify  new  targets  within  the 
Company’s significant land holding in Mato Grosso. There are currently four drill rigs operating on the property.

•  Annual  production  guidance  for the Curaçá Valley operations of 41,000 to 43,000 tonnes of copper in 

concentrate. 

•  C1  cash  cost guidance  of  US$0.85  to  US$0.95  per  pound  of  copper  produced  and  capital  expenditure 

guidance of US$74.0 million[1]. 

•  An additional US$28 million[1] to fund the 2020 exploration program in the Curaçá Valley.  The program is 
highlighted by 172,000 meters of planned exploration drilling through September 2020, an annualized 
rate of approximately 230,000 meters, of which approximately 60% is planned for regional exploration 
including  drill  testing  of  new  greenfield  targets  identified  during  the  Company’s  airborne  geophysical 
survey and ongoing data analysis. This compares to approximately 235,000 meters drilled during 2019 of 
which only 23% was allocated to regional exploration. 

•  Annual production guidance for the NX Gold Mine of 38,000 to 40,000 ounces of gold at C1 cash costs of 
US$475 to US$575 per ounce of gold produced. Annual capital expenditure guidance for the NX Gold Mine 
of US$5.7 million plus US$3.5 million[1] in ongoing exploration expenditures.

future exploration success and subject to further review and revision. 

Mineração Caraíba S.A. 

Copper production from the Curaçá Valley operations for 2020 is expected to be between 41,000 and 43,000 
tonnes, with ore fed solely from the Pilar and Vermelhos underground mines. Production from the Pilar Mine is 
expected to contribute a total of approximately 1.4 million tonnes grading 1.40% copper while production from 
the Vermelhos  Mine is expected to  contribute a total of approximately 750,000 tonnes  grading 3.50% copper 
resulting in a blended mill head grade of approximately 2.15% copper. 

NX Gold S.A.  

Approximately 150,000 tonnes of ore will be mined and processed from the Santo Antonio vein in 2020 at an 
average  grade  of  9.00  grams  per  tonne  of  gold.  Following  average  metallurgical  recoveries  of  90.0%,  Gold 
production from the NX Gold Mine is expected to reach 38,000 to 40,000 ounces. 

Boa Esperança 

A full review of the Boa Esperança Feasibility Study1 remains ongoing with the goal of extending the potential 
mine life and increasing copper production among other desktop optimization initiatives. The Company expects 
to provide an update on these initiatives during the first half of 2020.

1.  Revenues for Q4 2019 from copper sales was $67.7 million (Q4 2018 - $72.3 million), which included the sale of 11,595 copper tonnes in 
concentrate as compared to 12,900 copper tonnes for Q4 2018.  The Company processed 24% less ore at a higher ore grade during Q4 2019 
compared to Q4 2018.  Revenues for Q4 2019 from gold sales was $8.0 million (Q4 2018 - $12.8 million), which included the sale of 5,810 
ounces of gold, compared to 10,603 ounces of gold for Q4 2018. 

2. 

Cost of product sold for Q4 2019 from copper sales was $35.6 million (Q4 2018 - $36.9 million) which consisted of $11.1 million (Q4 2018 - 
$9.3 million) in depreciation and depletion, $9.4 million (Q4 2018 - $8.5 million) in salaries and benefits, $4.6 million (Q4 2018 - $5.7 million) 
in materials and consumables, $4.3 million (Q4 2018 - $7.3 million) in contracted services, $3.9 million (Q4 2018 - $3.4 million) in maintenance 
costs, $2.2 million (Q4 2018 - $2.5 million) in utilities, and $0.2 million (Q4 2018 - $0.2 million) in other costs.     

Cost of product sold for Q4 2019 from gold sales was $7.4 million (Q4 2018 - $7.8 million) which primarily comprised of $2.2 million (Q4 2018 
- $1.8 million) in salaries and benefits, $1.2 million (Q4 2018 - $0.8 million) in contracted services, $1.2 million (Q4 2018 - $1.4 million) in 
maintenance costs, $1.1 million (Q4 2018 - $1.3 million) in materials and consumables, $0.9 million (Q4 2018 - $1.8 million) in depreciation 
and depletion, and $0.7 million (Q4 2018 - $0.6 million) in utilities. 

3.  General and administrative expenses for Q4 2019 include $10.3 million (Q4 2018 - $3.8 million) with respect to MCSA for salaries and incentive 
payments, professional fees, office and sundry and provisions for tax, legal and labour claims, $0.5 million (Q4 2018 - $1.8 million) with respect 
to NX Gold for salaries and incentive payments, professional fees, office and sundry and provisions for tax, legal and labour claims, and $1.9 
million (Q4 2018 - $4.8 million) with respect to the corporate head office in Vancouver.  Corporate head office costs are primarily comprised 
of $1.4 million (Q4 2018 - $4.0 million) in salaries, incentive payments, and consulting fees, $0.3 million (Q4 2018 - $0.2 million) in travel-
related costs, and $0.2 million (Q4 2018 - $0.4 million) in professional fees.  Increases in general and administrative expenses in Q4 2019 as 
compared to Q4 2018 reflect the growth of operations, which included higher headcounts, incentive payments for exceeding board-mandated 
performance targets during 2019, as well as rate increases related to annual union contract negotiations at MCSA. 

4. 

5. 

Finance expense for Q4 2019 was $2.0 million (Q4 2018 - $6.8 million) and is primarily comprised of interest on loans at the corporate head 
office of $2.0 million (Q4 2018 - $1.5 million), interest on loans and borrowings at MCSA and NX Gold of $0.7 million (Q4 2018 - $3.1 million), 
commitment fees of $0.5 million (Q4 2018 - $0.6 million), partially offset by other finance income of $1.0 million (Q4 2018 - $2.0 million), and 
the reduction of asset retirement obligation accretion of $0.2 million (Q4 2018 - accretion of $3.8 million).  Interest on loans and borrowings 
at MCSA and NX Gold decreased due to the repayments of certain loans during 2018 and 2019. 

Foreign exchange gain for Q4 2019 was $4.4 million (Q4 2018 - $7.4 million).  This amount is primarily comprised of a foreign exchange gain 
on USD denominated debt of $3.8 million (Q4 2018 - $4.8 million) in MCSA for which the functional currency is the Brazilian Real and a foreign 
exchange gain on unrealized derivative contracts of $1.4 million (Q4 2018 - $4.0 million), partially offset by a foreign exchange loss on realized 
derivative contracts of $0.5 million (Q4 2018 - $1.0 million).  The decrease in foreign exchange  gains was primarily a result of the foreign 
exchange rate between the Brazilian Real and the US dollar fluctuating less during Q4 2019 as compared to Q4 2018 and a decrease in the 
outstanding USD denominated debt held in MCSA. 

6. 

In Q4 2018, the Company recognized a loss on settlement of debt of $5.5 million, comprising of a $3.7 million loss in early repayment fees for 
the settlement of certain debt in MCSA and a $1.8 million loss in loan settlement fees when the Company replaced its $50 million senior 
secured non-revolving credit facility with a $130 million facility from a syndicate of Canadian financial institutions. 

7.  Other income for Q4 2019 was $0.4 million (Q4 2018 - other expense of $5.6 million). Other income for Q4 2019 was not significant. Other 

expense in Q4 2018 primarily consisted of the write-off of state tax credits claimed that were deemed not recoverable for MCSA and NX 
Gold of $2.6 million and $1.6 million, respectively. 

8. 

In Q4 2019, the Company recognized a $25.2 million income tax recovery (Q4 2018 - income tax expense of $6.9 million), primarily resulting 
from the recognition of available tax losses and tax credits in MCSA and partially offset by current tax expense in the period.  At December 31, 
2019, the Company considered the taxable income generated since acquisition of MCSA and forecasted future taxable income and determined 
that it was now considered probable that the benefit of these losses and tax credits in MCSA would be realized.

Notes: 

1.  Revenues for Fiscal 2019 from copper sales was $246.2 million (Fiscal 2018 - $184.7 million) which included the sale of 42,759 copper tonnes 
in concentrate in Fiscal 2019 as compared to 30,107 copper tonnes in Fiscal 2018.  The increase in revenue in Fiscal 2019 as compared to Fiscal 
2018 includes production from the Vermelhos mine which commenced commercial production in October 2018.  The Company processed 
64% more ore at a higher ore grade during Fiscal 2019 as compared to Fiscal 2018.  In addition, revenues for Fiscal 2019 included $38.6 million 
(Fiscal 2018 - $48.4 million) from the sale of 29,755 (Fiscal 2018 - 39,808) ounces of gold from NX Gold operations. 

2.  Cost of product sold for Fiscal 2019 from copper sales was $135.6 million (Fiscal 2018 - $115.3 million), which consisted of $40.1 million (Fiscal 
2018 - $34.1 million) in depreciation and depletion, $33.7 million (Fiscal 2018 - $29.7 million) in salaries and benefits, $20.5 million (Fiscal 
2018 - $17.6 million) in contracted services, $17.9 million (Fiscal 2018 - $14.9 million) in materials and consumables, $14.1 million (Fiscal 2018 
- $10.8 million) in maintenance costs, $8.7 million (Fiscal 2018 - $7.5 million) in utilities, and $0.7 million (Fiscal 2018 - $0.7 million) in other 
costs.  Cost of products sold during Fiscal 2019 increased 18% as compared to Fiscal 2018.  Higher recoveries, higher ore grade, and efficiencies 
contributed towards cost containment relative to the increase in production volume.  The increase in cost of products sold in Fiscal 2019 
compared to Fiscal 2018 was primarily due to more copper being produced and sold as a result of the commencement of production at the 
Vermelhos underground mine in October 2018.   

Cost of product sold during Fiscal 2019 from gold sales was $27.2 million (Fiscal 2018 - $32.3 million), which comprised of $5.9 million (Fiscal 
2018 - $11.1 million) in depreciation and depletion, $7.1 million (Fiscal 2018 - $6.4 million) in salaries and benefits, $4.3 million (Fiscal 2018 - 
$5.0 million) in maintenance costs, $3.9 million (Fiscal 2018 - $4.5  million) in materials and consumables,  $3.2 million (Fiscal 2018 - $3.2 
million) in contracted services, $2.5 million (Fiscal 2018 - $1.8 million) in utilities, and $0.3 million (Fiscal 2018 - $0.3 million) in other costs.        

3.  General and administrative expenses during Fiscal 2019 include $21.0 million (Fiscal 2018 - $16.3 million) with respect to MCSA for salaries 
and incentive payments, professional fees, office and sundry and provisions for tax, legal and labour claims, $2.3 million (Fiscal 2018 - $3.4 
million) with respect to NX Gold for salaries and incentive payments, professional fees, office and sundry and provisions for tax, legal and 
labour claims and $9.5 million (Fiscal 2018 - $9.3 million) with respect to the corporate head office in Vancouver.  Corporate head office costs 
are primarily comprised of $6.7 million (Fiscal 2018  - $6.4 million) in salaries, incentive payments, and consulting fees, $1.2 million (Fiscal 
2018 - $0.9 million) in travel-related costs, $0.7 million (Fiscal 2018 - $1.0 million) in office and sundry costs, and $0.5 million (Fiscal 2018 - 
$0.9 million) in professional fees.  Increases in general and administrative expenses in Fiscal 2019 as compared to Fiscal 2018 reflect the growth 
of operations, which included higher headcounts, incentive payments for exceeding board-mandated performance targets during 2019, as 
well as rate increases related to annual union contract negotiations at MCSA.

6. 

Finance expense for Fiscal 2019 was $20.4 million (Fiscal 2018 - $22.6 million) and is primarily comprised of interest on loans at the corporate 
head office of $8.3 million (Fiscal 2018 - $5.4 million), interest on loans and borrowings at MCSA and NX Gold of $2.9 million (Fiscal 2018 - $9.6 
million), the accretion of asset retirement obligations of $3.5 million (Fiscal 2018 - $3.8 million), commitment fees of $1.7 million (Fiscal 2018 
- $0.6 million), and other finance expenses of $3.1 million (Fiscal 2018 - $2.6 million).  Interest on loans and borrowings at MCSA and NX Gold 
decreased due to the repayments of certain loans during 2018 and 2019, while interest on loans at the corporate head office increased due 
to the senior secured non-revolving credit facility entered into in December 2018, the proceeds of which were used to repay or settle debt at 
MCSA. 

Foreign exchange  loss for Fiscal 2019 was $5.1 million (Fiscal 2018 - $20.7 million), primarily comprised of a foreign exchange  loss on US 
denominated debt of $4.4 million (Fiscal 2018 - $9.8 million) in MCSA where the functional currency is the Brazilian Real, a loss on other 
foreign exchange transactions of $0.7 million (Fiscal 2018 - $1.9 million), and a foreign exchange loss on unrealized derivative contracts of $0.3 
million (Fiscal 2018 - $1.1 million gain), partially offset by a foreign exchange gain on realized derivative contracts of $0.2 million (Fiscal 2018 
- $10.1 million loss).  The decrease in foreign exchange losses in Fiscal 2019 was primarily due to the foreign exchange rate between the 
Brazilian Real and the US dollar not fluctuating significantly during Fiscal 2019 as compared to Fiscal 2018 and a decrease in the outstanding 
USD denominated debt held in MCSA. 

Loss on debt settlement during Fiscal 2019 was $1.8 million (Fiscal 2018 - $5.5 million), representing the difference between the accounting 
fair value made to legally extinguish a bank loan held by MCSA during the second quarter of 2019 and the carrying value of the loan at the 
time.  Loss on settlement of debt during Fiscal 2018 of $5.5 million was incurred in Q4 2018, comprising of a $3.7 million loss in early repayment 
fees for the settlement of certain debt in MCSA and a $1.8 million loss in loan settlement fees when the Company replaced its $50 million 
senior secured non-revolving credit facility with a $130 million facility from a syndicate of Canadian financial institutions. 

7.  During  Fiscal  2019,  the  Company  recognized  a  recovery  of  $21.6  million  (Fiscal  2018  -  $nil)  in  net  income  related  to  value  added  taxes 
previously paid on sales in Brazil.  The recovery was recognized as a result of a Brazil Supreme Court ruling in 2017 that concluded that the 
relevant  taxing  authorities  had  historically  used  an  incorrect  methodology  to  determine  such  taxes.    The  ruling  set  a  precedent  for  all 
companies in Brazil but was required to be confirmed for the Company’s specific claim, which approval was received in July 2019.  These 
credits can be used to offset a variety of other taxes, including taxes on future sales.  Of the recovery recognized, $3.2 million has been applied 
to taxes in the current year,  $12.2 million  has been included  in other current assets based on the expected timing of their use, with the 
remaining $6.2 million recognized in other non-current assets in the statement of financial position. 

8.  During Fiscal 2019, the Company recognized a $17.6 million income tax recovery (Fiscal 2018 - income tax expense of $5.7 million), primarily 
resulting from the recognition of available tax losses and tax credits in MCSA and partially offset by current income tax expense.  Current tax 
exposure  increased  as  a  result  of  higher  taxable  income  in  MCSA.    At  December  31,  2019,  the  Company  considered  the  taxable  income 
generated since acquisition of MCSA and forecasted future taxable income and determined that it was now considered probable that the 
benefit of these losses and tax credits in MCSA would be realized.

Notes: 
1.  During Q4 2019, the Company recognized a $25.2 million income tax recovery primarily resulting from the recognition of available tax 
losses and tax credits in MCSA.  At December 31, 2019, the Company considered the taxable income generated since acquisition of 
MCSA and forecasted future taxable income and determined that it was now considered probable that the benefit of these losses and 
tax credits in MCSA would be realized. 

2.  During the quarter ended September 30, 2019, the Company recognized a recovery of $21.6 million in net income related to value 
added taxes previously paid on sales in Brazil.  The recovery was recognized as a result of a Brazil Supreme Court ruling in 2017 that 
concluded that the relevant taxing authorities had historically used an incorrect methodology to determine such taxes.  The ruling set 
a precedent for all companies in Brazil but was required to be confirmed for the Company’s specific claim, for which approval was 
received in July 2019.  These credits can be used to offset a variety of other taxes, including income taxes and taxes on future sales.   
3.  During Q4 2018, MCSA began commercial production of the Vermelhos Mine.  This resulted in increased sales this quarter, generating 

higher net income for the period.   

4.  During the quarter ended June 30, 2018, the Company had an overall net loss of $18.2 million, which included $26.4 million in foreign 
exchange losses.  The foreign exchange losses were comprised of a $12.2 million loss associated with US dollar denominated debt held 
by MCSA, whose functional currency is the Brazilian Real, $11.4 million loss on foreign exchange forward contracts and $2.8 million 
related to other operational exchange losses.  The foreign exchange losses were unusually high this quarter due to volatility in the 
foreign exchange rates between the US dollar and the Brazilian Real. 

LIQUIDITY, CAPITAL RESOURCES, AND CONTRACTUAL OBLIGATIONS 

Liquidity 

As at December 31, 2019, the Company held cash and cash equivalents of $21.5 million. Cash and cash equivalents 
are primarily comprised of cash held with reputable financial institutions and are invested in highly liquid short-
term investments with maturities of three months or less. The funds are not exposed to liquidity risk and there 
are no restrictions on the ability of the Company to use these funds to meet its obligations. 

Cash and cash equivalents increased by $2.5 million during Fiscal 2019. The Company’s cash flows from operating, 
investing and financing activities during Fiscal 2019 are summarized as follows: 

•  Cash from operating activities of $127.8 million.  

Partially offset by: 

•  Cash used in investing activities of $106.7 million, including: 

o  $105.4 million of additions to mineral property, plant and equipment; 
o  $0.9 million of additions to exploration and evaluation assets; 
o  $0.5 million of additions to financial investments 

•  Cash flows used in financing activities of approximately $18.0 million, including:

o  $41.3 million of repayment on loans and borrowings; 
o  $10.3 million of payment of interest on loans and borrowings; 
o  $4.1 million of lease payments; 
o  $3.7 million of other finance expenses 

net of: 

o  $37.9 million proceeds from new loans and borrowings; 
o  $1.9 million proceeds from exercise of stock options and warrants; 
o  $1.5 million released from restricted cash 

As at December 31, 2019, the Company had working capital deficit of $4.9 million.  

Capital Resources 

The Company’s primary sources of capital are comprised of cash from operations, cash and cash equivalents on 
hand  and  undrawn debt  facilities.   The Company will continuously monitor its capital structure and, based on 
changes in operations and economic conditions, may adjust such structure by issuing new common shares or new 
debt as necessary.  While the Company has been successful in securing financing to date, there are no guarantees 
that it will be able to secure such financing in the future on terms acceptable to the Company, if at all.  Taking into 
consideration cash flow from existing operations, and the existing undrawn revolving credit facility of $14.0 million 
in Canada and undrawn lines of credit totalling R$64.8 million in MCSA as at December 31, 2019, management 
believes  that  the  Company  has  sufficient  working  capital  and  financial  resources  to  maintain  its  planned 
operations and activities for the foreseeable future.      

Contractual Obligations and Commitments 

Certain loan agreements contain operating and financial covenants that could restrict the ability of the Company 
and its subsidiaries, MCSA and NX Gold S.A., to, among other things, incur additional indebtedness needed to fund 
its  respective  operations,  pay  dividends  or  make  other  distributions,  make  investments,  create  liens,  sell  or 
transfer assets or enter into transactions with affiliates. There  are no other restrictions or externally imposed 
capital requirements of the Company. 

MANAGEMENT OF RISKS AND UNCERTAINTIES 

The Company thoroughly examines the various financial instruments and risks to which it is exposed and assesses 
the impact and likelihood of those risks. These risks may include credit risk, liquidity risk, currency risk, commodity 
price risk and interest rate risk. Where material, these risks are reviewed and monitored by the Board.

Credit risk  

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails 
to meet its contractual obligations and arises principally from the Company’s receivables from customers. The 
carrying amount of the financial assets below represents the maximum credit risk exposure as at December 31, 
2019 and December 31, 2018:

The  Company  invests  cash  and  cash  equivalents  as  well  as  restricted  cash  with  financial  institutions  that  are 
financially sound based on their credit rating.  The Company’s exposure to credit risk associated with accounts 
receivable is influenced mainly by the individual characteristics of each customer.  The Company currently has 
only three significant customers, all of which have no history of credit default with the Company.  The Company 
has not incurred credit losses during the years ended December 31, 2019 and 2018 nor has a provision for credit 
losses been recognized.     

Liquidity risk  

Liquidity  risk  is  the  risk  associated  with  the  difficulties  that  the  Company  may  have  meeting  the  obligations 
associated  with  financial  liabilities  that  are  settled  with  cash  payments  or  with  another  financial  asset.  The 
Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to 
meet their maturity obligations on the expiration dates, under normal and stressful conditions, without causing 
unacceptable losses or with risk of undermining the normal operation of the Company.

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange 
rates, and commodity prices.  The purpose of market risk management is to manage and control exposures to 
market risks, within acceptable parameters, while optimizing return. 

The Company may use derivatives, including forward contracts and swap contracts, to manage market risks.

Foreign exchange currency risk  

The Company’s subsidiaries in Brazil are exposed to exchange risks related to the US dollars and Euros.  In order 
to  minimize  currency  mismatches,  the  Company  monitors  its  cash  flow  projections  considering  future  sales 
expectations indexed to US dollar variation in relation to the cash requirement to settle the existing financings. 

The Company's exposure to foreign exchange currency risk at December 31, 2019 relates primarily to $9.6 million 
(December  31, 2018 –  $10.2  million)  in  loans  and  borrowings  of  MCSA  denominated  in  US  dollars  and  Euros. 
Strengthening  (weakening)  in  the  Brazilian  Real  against  the  US  dollar  by  10%  and  20%,  would  have  increased 
(decreased) pre-tax net income by $0.6 million and $1.1 million, respectively (2018 – $0.7 million and $1.3 million). 
Strengthening  (weakening)  in  the  Brazilian  Real  against  the  Euro  by  10%  and  20%,  would  have  increased 
(decreased) pre-tax net income by $0.4 million and $0.8 million, respectively (2018 – $0.4 million and $0.7 million). 
This  analysis  is  based  on  the  foreign  currency  exchange  variation  rate  that  the  Company  considered  to  be 
reasonably possible at the end of the year. The analysis assumes that all other variables, especially interest rates, 
are held constant. 

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage market 
risks.  At December 31, 2019, the Company’s subsidiaries have entered into foreign exchange collar contracts at 
zero cost for notional amounts of $336.6 million with an average floor rate of 3.86 R$ / $  and an average cap rate 
of 4.41 R$ / $ (December 31, 2018 – notional amount of $21.5 million in foreign exchange forward contracts).  The 
maturity dates of these contracts are from January 15, 2020 to July 28, 2021 and are financially settled on a net 
basis.  The fair value of these contracts at December 31, 2019 was nil, (December 31, 2018 – an asset of $0.3 
million,  which  was  included  in  Derivatives  in  the  statement  of  financial  position.)    The  change  in  fair  value  of 
foreign exchange collar contracts was a loss of $0.3 million for the year ended December 31, 2019 and (a gain of 
$1.1 million for the year ended December 31, 2018) has been recognized in foreign exchange loss.  In addition, in 
the year ended December 31, 2019, the Company recognized a realized gain of $0.2 million, (a loss of $10.1 million 
for the year ended December 31, 2018) related to the settlement of foreign currency forward contracts. 

Interest rate risk 

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates 
of interest.   Management reduces interest rate risk exposure by entering into loans and borrowings with fixed 
rates of interest or by entering into derivative instruments that fix the ultimate interest rate paid. 

The Company is principally exposed to interest rate risk through its senior credit facilities of $136.0 million and 
Brazilian Real denominated bank loans of $9.8 million.  Based on the Company’s net exposure at December 31, 
2019,  a  1%  change  in  the  variable  rates  would  have  an  impact  of  $1.5  million  on  pre-tax  annual  net  income, 
without consideration of the effects of the swap contracts below. 

In order to mitigate the above volatility due to variable rates on loans, as at December 31, 2019, the Company has 
entered  into  an  interest  rate  swap  contract  to  manage  interest  rate  risk  associated  with  its  Canadian  credit 
facilities.  The floating interest on a notional amount of $65 million was swapped for a fixed interest rate of 2.69%.  
The fair value of this contract at December 31, 2019 was a liability of $1.7 million and was included in Derivatives 
in the statement of financial position. 

In addition, as at December 31, 2019, MCSA has entered into an interest rate and currency swap contract on the 
Plural Loan.  The floating interest on a notional amount of R$12 million was swapped for a fixed interest rate of 
9.9% and the BRL currency on the loan was swapped for USD at a rate of 3.9500.  The fair value of this contract at 
December 31, 2019 was a liability of $0.1 million and was included in derivatives in the statement of financial 
position while the change in the fair value of this contract of $0.1 million was included in Finance Expenses in the 
statement of operations and comprehensive income.

Price risk  

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity 
price risks.  During the year ended December 31, 2019, the Company had entered into commodity swap collar 
contracts.  As at December 31, 2019, these commodity swap collar contracts have all matured and the balance 
was $nil.  The Company recognized a realized loss of $1.4 million for the year ended December 31, 2019 related 
to the settlement of commodity forward contracts.   

For  a  discussion  of  additional  risks  applicable  to  the  Company  and  its  business  and  operations,  including  risks 
related to the Company’s foreign operations, the environment and legal proceedings, see “Risk Factors” in the 
Company’s Annual Information Form for the year ended December 31, 2019 and dated March 12, 2020 (the “AIF”). 

OTHER FINANCIAL INFORMATION 

Off-Balance Sheet Arrangements 

As at December 31, 2019, the Company had no material off-balance sheet arrangements.  

Contingencies 

With the acquisition of MCSA, the Company inherited certain liabilities and MCSA has been subject to a number 
of claims (including claims related to tax, labour and social security matters and civil action) in the course of its 
business which individually are not material and have not been accrued for in the Company’s financial statements 
as it is not probable that a cash outflow will occur. While the Company believes that these claims are unlikely to 
be successful, if all such existing claims were decided against it, the Company could be exposed to a liability of up 
to approximately $31.1 million as at December 31, 2019 (December 31, 2018 - $21.9 million), which could have 
an adverse impact on the Company’s business, financial condition, results of operations, cash flows or prospects. 

Outstanding Share Data 

At March 12, 2020, the Company had 85,756,978 common shares, 5,081,541 stock options, 2,866,662 warrants, 
and 438,463 performance share units issued and outstanding.  

Related Party Disclosures 

For the year ended December 31, 2019, amounts paid to related parties were incurred in the normal course of 
business and measured at the exchange amount, which is the amount agreed upon by the transacting parties and 
on terms and conditions similar to non-related parties.  

Key  management  personnel  consist  of  the  Company’s  directors  and  officers  and  their  compensation  includes 
director retainer fees and management salaries paid to these individuals, as well as share-based compensation.  
The aggregate value of compensation paid to key management personnel for the year ended December 31, 2019 
was $7.5 million ($5.4 million for the year ended December 31, 2018).  In addition, 444,265 options and 171,754 
share  units  were  issued  to  key  management  personnel  during  the  year  ended  December  31, 2019  (1,100,155 
options and 130,636 share units for the year ended December 31, 2018), with $4.1 million recognized in share-
based compensation expense for the year ended December 31, 2019 ($2.3 million for the year ended December 
31, 2018).   

During the year ended December 31, 2019, key management personnel exercised 286,666 options and 300,000 
warrants for cash proceeds to the Company of $0.6 million and $0.4 million, respectively (133,000 options for $0.2 
million for the year ended December 31, 2018).  During the year ended December 31, 2018, key management 
personnel converted convertible debentures into 1,476,164 common shares and 369,040 common share purchase 
warrants.  The warrants were subsequently exercised into 369,040 common shares.

As at December 31, 2019, $3.9 million was payable to key management as incentive compensation and is included 
in the accounts payable and accrued liabilities in the consolidated financial statements (December 31, 2018 - $2.7 
million).  Such amounts were unsecured, non-interest bearing and were repaid under normal trade terms. 

Subsequent to December 31, 2019, 23,674 deferred share units were issued to directors, and 43,456 options were 
granted to directors. 

ACCOUNTING POLICIES, JUDGMENTS AND ESTIMATES 

Critical Accounting Judgments and Estimates 

The  preparation  of  consolidated  financial  statements  in  conformity  with  IFRS  requires  management  to  make 
judgments,  estimates  and  assumptions  about  future  events  that  affect  the  reported  amounts  of  assets  and 
liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the 
reporting period. Although these estimates are based on management’s best knowledge of the amount, events 
or actions, actual results may differ from these estimates.  

The  Company’s  significant  accounting  policies  and  accounting  estimates  are  contained  in  the  Company’s 
December  31,  2019  consolidated  financial  statements.  Certain  of  these  policies,  such  as,  capitalization  and 
depreciation  of  property,  plant  and  equipment  and  mining 
instruments,  and 
decommissioning liabilities provisions involve critical accounting estimates because they require management of 
the Company to make subjective or complex judgments about matters that are inherently uncertain, and because 
of the likelihood that materially different amounts could be reported under different conditions or using different 
assumptions.  

interests,  derivative 

In preparing its financial statements, management has made judgments, estimates and assumptions that affect 
the application of the Company’s accounting policies and the reported amounts of the assets, liabilities, revenues 
and expenses.  Actual results may differ from these estimates.   

The  estimates  and  assumptions  are  reviewed  on  an  ongoing  basis.    Revisions  to  estimates  are  recognized 
prospectively. 

Critical Judgments  

Functional currency 

The  functional  currency  of  the  Company  and  each of  its  subsidiaries  is  the  currency of  the  primary  economic 
environment in which the entities operate.  The Company has determined that the functional currency for the 
Company is the US dollar while the functional currency for MCSA and NX Gold is the Brazilian Real. Assessment of 
functional  currency  involves  certain  judgements  to  determine  the  primary  economic  environment  and  the 
Company reconsiders the functional currency of its entities if there is a change in events and conditions which 
determined the primary economic environment.

Legal claims and contingent liabilities 

The recognition of legal provisions and contingent liabilities involves the assessment of claims made against the 
Company and each of its subsidiaries.  The recognition of a legal provision, or disclosure of a contingent liability, 
involves certain judgements to determine the probability of whether a cash outflow will occur.  In making this 
judgment, management has assessed various criteria and also relies on the opinions of its legal advisers to assist 
in making this assessment. 

Key Sources of Estimation Uncertainty  

The preparation of  financial  statements in conformity with IFRS requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and the disclosure of assets and liabilities 
at the date of the consolidated financial statements and the reported amounts of expenses during the reporting 
periods.  Actual  results  could  differ  from  those  estimates  and  such  differences  could  be  significant.  Significant 
estimates made by management affecting the consolidated financial statements include:  

Impairment of property, plant and equipment 

The Company evaluates each asset or cash generating unit every reporting period to determine whether there 
are any indications of impairment. If any such indication exists, which is often judgmental, a formal estimate of 
recoverable amount is performed and an impairment loss is recognized to the extent that the carrying amount 
exceeds  the  recoverable  amount.  The  recoverable  amount  of  an  asset  or  cash  generating  group  of  assets  is 
measured at the higher of fair value less costs to sell and value in use. The evaluation of asset carrying values for 
indications of impairment includes consideration of both external and internal sources of information, including 
such factors as market and economic conditions, production budgets and forecasts, and life-of-mine estimates. 

When required, the determination of fair value and value in use requires management to make estimates and 
assumptions  about  expected  production,  sales  volumes,  commodity  prices,  mineral  reserves,  operating  costs, 
closure and rehabilitation costs and future capital expenditures. The estimates and assumptions are subject to 
risk  and  uncertainty;  hence,  there  is  the  possibility  that  changes  in  circumstances  will  alter  these  projections, 
which may impact the recoverable amount of the assets. In such circumstances, some or all of the carrying value 
of the assets may be further impaired or the impairment charge reduced with the impact recorded in profit or 
loss. 

Mineral reserve and resource estimates including life of mine plan 

The Company estimates its mineral reserves and mineral resources based on information compiled by competent 
individuals.    Mineral  reserves  are  used  in  the  calculation  of  depreciation,  impairment  assessments  and  for 
forecasting the timing of payment of mine closure and rehabilitation costs. 

There are numerous uncertainties inherent in estimating mineral reserves, and assumptions that are valid at the 
time of estimation may change significantly when new information becomes available.  Changes in the estimation 
methodology, forecasted prices of commodities, exchange rates, production costs or recovery rates may change 
the economic status of mineral reserves and may, ultimately, result in changes in the mineral reserves. 

The carrying amounts of the Company’s mineral properties, plant and equipment are depleted in part based on 
recoverable  mineral  reserve  tonnes  processed,  depending  on  the  use  of  the  asset.    Changes  to  estimates  of 
recoverable quantities of metals, mineral reserve tonnes and depletable costs, including changes resulting from 
revisions to the Company’s mine plans and changes in metals prices forecasts, can result in a change to future 
depreciation and depletion rates and may result in impairment charges. 

Mine closure and rehabilitation costs 

ERO COPPER | 2019 ANNUAL REPORT | 29 

 
 
 
 
 
 
 
 
 
 
 
 
Significant estimates and assumptions are made in determining the provision for mine closure and rehabilitation 
as there are numerous factors that will affect the ultimate liability payable.  These factors include estimation of 
the  extent  and  cost  of  rehabilitation  activities,  timing  of  future  cash  flows,  discount  rates,  inflation  rate,  and 
regulatory requirements. 

Changes in the above factors can result in a change to the provision recognized by the Company.  Changes to mine 
closure and  rehabilitation costs  are recorded with a corresponding change to the carrying amounts of related 
mineral properties, plant and equipment.  Adjustments to the carrying amounts of related mineral properties, 
plant and equipment can result in a change to future depreciation and depletion expense. 

Significant assumptions used to determine mine closure and rehabilitation costs are included in Note 11(a) to the 
consolidated financial statements.  

Inventory 

The net recoverable value of stockpile inventory and production in work in progress inventory is based on the 
quantity of recoverable metal inventory which is an estimate based on the tons of ore added and removed from 
the  process,  expected  grade  and  recovery  rates.  The  quantity  of  recoverable  metal  in  finished  concentrate 
inventory is an estimate based on initial weights and assay results.  The net recoverable value of these inventories 
also requires estimates of expected selling prices and, where applicable, costs to complete. 

Income taxes 

The determination of the Company’s tax expense for the period and deferred tax assets and liabilities involves 
significant estimation and judgement by management. In determining these amounts, management interprets tax 
legislation in a variety of jurisdictions and makes estimates of the expected timing of the reversal of deferred tax 
assets  and  liabilities.  Management  also  makes  estimates  of  future  earnings,  which  affect  the  extent  to  which 
potential future tax benefits may be used. The Company is subject to assessments by various taxation authorities, 
which may interpret legislation differently. These differences may affect the final amount or the timing of the 
payment  of  taxes.  The  Company  provides  for  such  differences  where  known  based  on  management’s  best 
estimate of the probable outcome of these matters. 

New Accounting Standards Adopted in the Current Period 

The following new and amended IFRS pronouncements were adopted effective January 1, 2019: 

i) 

IFRS 16 Leases 

IFRS 16 introduces a single, on-balance sheet accounting model for lessees.  As a result, the Company, as a 
lessee,  has  recognized  right-of-use  assets  representing  its  rights  to  use  the  underlying  assets  and  lease 
liabilities representing its obligation to make lease payments.  The Company may elect to not apply IFRS 16 to 
leases with a term of less than 12 months, which election is made by underlying class of assets to which the 
right of use asset relates, or leases where the underlying asset is of low value, which election is made on an 
asset by asset basis. Lessor accounting remains similar to previous accounting policies. 

Previously, the Company determined at contract inception whether an arrangement was or contained a lease 
under IFRIC 4, Determining Whether an Arrangement contains a Lease.  The Company now assesses whether 
a  contract  is  or  contains  a  lease  based  on  the  new  definition  of  a  lease.    Under  IFRS  16,  a  contract  is,  or 
contains, a lease if the contract conveys a right to control the use of an identified asset for a period of time in 
exchange for consideration.  

ERO COPPER | 2019 ANNUAL REPORT | 30 

 
 
 
 
 
 
 
 
 
 
 
The  Company  adopted  IFRS  16  using  the  modified  retrospective  approach.  Accordingly,  the  comparative 
information presented for 2018 has not been restated.  The impact of adoption of IFRS 16 is disclosed in note 
2(e) of the consolidated financial statements. 

As a result of applying IFRS 16, the Company recognized right-of-use assets of $4.7 million and lease liabilities 
of $4.7 million upon adoption. 

ii) 

IFRIC 23 – Uncertainty over Income Tax Treatments 

The  Company  has  adopted  IFRIC  Interpretation  23  (“Interpretation  23”)  –  Uncertainty  over  Income  Tax 
Treatments from January 1, 2019. The Interpretation provides guidance on the accounting for current and 
deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments.   
There is no material impact on the financial statements from the adoption of Interpretation 23.

NON-IFRS MEASURES 

Financial results of the Company are prepared in accordance with IFRS. The Company utilizes certain non-IFRS 
measures, including C1 cash cost of copper produced (per lb), C1 cash cost of gold produced (per ounce), EBITDA, 
Adjusted EBITDA, Adjusted net income (loss) attributable to owners of the Company, Adjusted earnings (loss) per 
share, net debt and working capital, which are not measures recognized under IFRS. The Company believes that 
these measures, together with measures determined in accordance with IFRS, provide investors with an improved 
ability to evaluate the underlying performance of the Company. Non-IFRS measures do not have any standardized 
meaning  prescribed  under  IFRS, and therefore they may not be comparable to similar measures employed by 
other companies. The data is intended to provide additional information and should not be considered in isolation 
or as a substitute for measures of performance prepared in accordance with IFRS.  The tables below provide a 
reconciliation  of  these  non-IFRS  measures to the most directly comparable IFRS measures as contained in the 
Company’s financial statements. 

Unless otherwise noted, the non-IFRS measures presented below have been calculated on a consistent basis for 
the periods presented.

C1 Cash Cost of Copper Produced (per lb)  

C1 cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development 
costs and by-product credits, divided by the copper pounds produced.  C1 cash costs reported by the Company 
include  treatment,  refining  charges,  offsite  costs,  and  certain  tax  credits  relating  to  sales  invoiced  to  the 
Company’s Brazilian customer on sales.  By-product credits are calculated based on actual precious metal sales 
(net of treatment costs) during the period divided by the total pounds of copper produced during the period.  C1 
cash cost of copper produced per pound is a non-IFRS measure used by the Company to manage and evaluate 
operating performance of the Company’s operating mining unit and is widely reported in the mining industry as 
benchmarks  for  performance  but  does  not  have  a  standardized  meaning  and  is  disclosed  in  addition  to  IFRS 
measures.   

The following table provides a reconciliation of C1 cash cost of copper produced per pound to cost of goods sold, 
its most directly comparable IFRS measure.

C1 Cash Cost of Gold produced (per ounce)  

C1 cash cost of gold produced (per ounce) is the sum of production costs, net of capital expenditure development 
costs and silver by-product credits, divided by the gold ounces produced.  By-product credits are calculated based 
on actual precious metal sales during the period divided by the total ounces of gold produced during the period.  
C1 cash cost of gold produced per pound is a non-IFRS measure used by the Company to manage and evaluate 
operating performance of the Company’s operating mining unit and is widely reported in the mining industry as 
benchmarks  for  performance  but  does  not  have  a  standardized  meaning  and  is  disclosed  in  addition  to  IFRS 
measures.   

The following table provides a reconciliation of C1 cash cost of gold produced per ounce to cost of goods sold, its 
most directly comparable IFRS measure.

EBITDA  represents  earnings  before  interest  expense,  income  taxes,  depreciation,  and  amortization.    Adjusted 
EBITDA includes further adjustments for non-recurring items and/or items not indicative to the future operating 
performance of the Company.  The Company believes EBITDA and adjusted EBITDA are appropriate supplemental 
measures of debt service capacity and performance of its operations. 

Adjusted EBITDA is calculated by removing the following income statement items: 

-  Recovery of value added taxes  
Foreign exchange loss (gain) 
- 
Loss on gold hedge contracts 
- 
Share based compensation 
- 
Loss on debt settlement

Adjusted  net  income  attributable  to  owners  of  the  Company  and  Adjusted  net  income  per  share 
attributable to owners of the Company 

The  Company  uses  the  financial  measure  “Adjusted  net  income  attributable  to  owners  of  the  Company”  and 
“Adjusted  net  income  per  share  attributable  to  owners  of  the  Company”  (“Adjusted  EPS”)  to  supplement 
information  in  its  consolidated  financial  statements.    The  Company  believes  that,  in  addition  to  conventional 
measures prepared in accordance with IFRS, the Company and certain investor and analysts use this information 
to evaluate the Company’s performance.  The Company excludes the following items from net earnings to provide 
a  measure  which  allows  the  Company  and  investors  to  evaluate  the  operating  results  of  the  underlying  core 
operations: i) net recovery of value added taxes, ii) share based compensation iii) unrealized foreign exchange loss 
(gain) on USD denominated debt in MCSA, iv) unrealized loss (gain) on foreign exchange derivative contracts, v) 
unrealized loss on gold hedge contracts, and vi) loss on debt settlement.  The presentation of Adjusted EPS is not 
meant to substitute the net income (loss) per share attributable to owners of the Company (“EPS”) presented in 
accordance with IFRS, but rather it should be evaluated in conjunction with such IFRS measures. 

The following table provides a detailed reconciliation of net income (loss) attributable to owners of the Company 
as reported in the Company’s consolidated financial statements to adjusted net income attributable to owners of 
the Company and Adjusted EPS.

The Company’s management, with the participation of the Chief Executive Officer (“CEO”) and the Chief Financial 
Officer (“CFO”), has evaluated the effectiveness of the Company’s disclosure controls and procedures (“DC&P”). 
Based on the results of that evaluation, the Company’s CEO and CFO have concluded that, as of December 31, 
2019, the Company’s DC&P were effective to provide reasonable assurance that the information required to be 
disclosed  by  the  Company  in  reports  it  files  is  recorded,  processed,  summarized,  and  reported  within  the

Internal Control over Financial Reporting 

The  Company’s  management,  with  the  participation  of  the  CEO  and  CFO,  is  responsible  for  establishing  and 
maintaining adequate internal control over financial reporting (“ICFR”). The Company’s ICFR is a process designed 
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with IFRS.  Any system of ICFR, no matter how well designed, has 
inherent limitations and cannot provide absolute assurance that all misstatements and instances of fraud, if any, 
within the Company have been prevented or detected. The Company’s ICFR is designed to provide reasonable 
assurance regarding the reliability of financial reporting and the preparation of financial statements for external 
purposes in accordance with IFRS.  

The Company uses the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  

The Company’s management, under the supervision of the CEO and CFO, has evaluated the design and operating 
effectiveness of the Company’s ICFR and concluded that the Company’s ICFR were effective as of December 31, 
2019. 

There were no changes in the Company’s ICFR that materially affected, or are reasonably likely to materially affect, 
ICFR during Q4 2019.

Cautionary Note Regarding Forward-Looking Statements  

This MD&A contains “forward-looking information” within the meaning of applicable Canadian securities laws. 
Forward-looking information includes statements that use forward-looking terminology such as “may”, “could”, 
“would”,  “will”,  “should”,  “intend”,  “target”,  “plan”,  “expect”,  “budget”,  “estimate”,  “forecast”,  “schedule”, 
“anticipate”, “believe”, “continue”, “potential”, “view” or the negative or grammatical variation thereof or other 
variations  thereof  or  comparable  terminology.  Such  forward-looking  information  includes,  without  limitation, 
statements with respect to the Company's expected operations at the Vermelhos and Pilar Mines as well as at the 
NX  Gold Property,  drilling plans,  plans  for  the  Company's  exploration  program,  timing of  any  updated mineral 
resource and reserve updates and technical reports, the Company's ability to service its ongoing obligations, the 
Company's future production outlook, cash costs, capital resources, expenditures, the impact of new accounting 
standards  and  amendments  on  the  Company's  financial  statements,  and  current  global  macroeconomic 
uncertainty stemming from the onset of Covid-19. 

Forward-looking information is not a guarantee of future performance and is based upon a number of estimates 
and  assumptions  of  management  in  light  of  management’s  experience  and  perception  of  trends,  current 
conditions and expected developments, as well as other factors that management believes to be relevant and 
reasonable in the circumstances, as of the date of this Press Release including, without limitation, assumptions 
about:  favourable  equity  and  debt  capital  markets;  the  ability  to  raise  any  necessary  additional  capital  on 
reasonable  terms  to  advance  the  production,  development  and  exploration  of  the  Company’s  properties  and 
assets; future prices of copper and other metal prices; the timing and results of exploration and drilling programs; 
the accuracy of any mineral reserve and mineral resource estimates; the geology of the Vale do Curaçá Property, 
NX Gold Property and the Boa Esperanҫa Property being as described in the technical reports for these properties; 
production costs; the accuracy of budgeted exploration and development costs and expenditures; the price of 
other commodities such as fuel; future currency exchange rates and interest rates; operating conditions being 
favourable  such  that  the  Company  is  able  to  operate  in  a  safe,  efficient  and  effective  manner;  political  and 
regulatory stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on 
favourable terms; obtaining required renewals for existing approvals, licenses and permits on favourable terms; 
requirements under applicable laws; sustained labour stability; stability in financial and capital goods markets; 
availability of equipment; positive relations with local groups and the Company’s ability to meet its obligations 
under its agreements with such groups; and satisfying the terms and conditions of the Company’s current loan 
arrangements. While the Company considers these assumptions to be reasonable, the assumptions are inherently 
subject to significant business, social, economic, political, regulatory, competitive, global health, and other risks 
and uncertainties, contingencies  and  other factors that could cause actual actions,  events, conditions,  results, 
performance or achievements to be materially different from those projected in the forward-looking information. 
Many assumptions are based on factors and events that are not within the control of the Company and there is 
no assurance they will prove to be correct. 

Furthermore, such forward-looking information involves a variety of known and unknown risks, uncertainties and 
other factors which may cause the actual plans, intentions, activities, results, performance or achievements of the 
Company  to  be  materially  different  from  any  future  plans,  intentions,  activities,  results,  performance  or 
achievements expressed or implied by such forward-looking information. Such risks include, without limitation 
the risk factors listed under the heading “Risk Factors” in the AIF.    

Although  the  Company  has  attempted  to  identify  important  factors  that  could  cause  actual  actions,  events, 
conditions,  results,  performance or  achievements to differ materially from those described in forward-looking 
information,  there  may  be  other  factors  that  cause  actions,  events,  conditions,  results,  performance  or 
achievements to differ from those anticipated, estimated or intended. 

ERO COPPER | 2019 ANNUAL REPORT | 38 

 
 
The Company cautions that the foregoing lists of important assumptions and factors are not exhaustive. Other 
events or circumstances  could  cause actual results to differ materially from those estimated or projected and 
expressed in, or implied by, the forward-looking information contained herein. There can be no assurance that 
forward-looking information will prove to be accurate, as actual results and future events could differ materially 
from those anticipated  in such  information. Accordingly, readers should not place undue reliance on forward-
looking information. 

Forward-looking information contained herein is made as of the date of this MD&A and the Company disclaims 
any obligation to update or revise any forward-looking information, whether as a result of new information, future 
events or results or otherwise, except as and to the extent required by applicable securities laws. 

Cautionary Notes Regarding Mineral Resource and Reserve Estimates 

In  accordance  with  applicable  Canadian  securities  regulatory  requirements,  all  mineral  reserve  and  mineral 
resource estimates of the Company disclosed or incorporated by reference in this MD&A have been prepared in 
accordance with NI 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and 
Petroleum (“CIM”) Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council 
on May 10, 2014 (the “CIM Standards”). 

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the 
CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence 
as  well  as  their  economic  and  legal  feasibility.  Inferred  mineral  resources,  when  compared  with  Measured  or 
Indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or 
any part of an Inferred mineral resource will be upgraded to an Indicated or Measured mineral resource as a result 
of  continued  exploration.  Pursuant  to  NI  43-101,  Inferred  mineral  resources  may  not  form  the  basis  of  any 
economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource 
exists,  will  ever  be  converted  into  a  mineral  reserve,  or  is  or  will  ever  be  economically  or  legally mineable  or 
recovered.

INDEPENDENT AUDITORS’ REPORT

To the Shareholders of Ero Copper Corp.

Opinion

We  have  audited  the  consolidated financial  statements  of  Ero  Copper  Corp.  (“the 
Company”), which comprise:

– the  consolidated statements  of  financial  position  as  at  December  31,  2019  and

December 31, 2018;

– the consolidated statements of operations and comprehensive income (loss), changes

in shareholders’ equity and cash flows for the years then ended; and

– notes to the consolidated statements, including a summary of significant accounting

policies

(Hereinafter referred to as the “financial statements”).

In  our  opinion,  the  accompanying  financial  statements  present  fairly,  in  all  material 
respects, the consolidated financial position of the Company as at December 31, 2019 and 
December  31,  2018,  and  its  consolidated financial  performance  and  consolidated  cash 
flows  for  the  years  then  ended  in  accordance  with  International  Financial  Reporting 
Standards.  

Basis for Opinion

We  conducted  our  audit  in  accordance  with  Canadian  generally  accepted  auditing 
standards.    Our  responsibilities  under  those  standards  are  further  described  in  the 
“Auditors’ Responsibilities for the Audit of the Financial Statements” section of our auditors’ 
report.  

We are independent of the Company in accordance with the ethical requirements that are 
relevant to our audit of the financial statements in Canada and we have fulfilled our other 
ethical responsibilities in accordance with these requirements.

We  believe  that  the  audit  evidence  we  have  obtained  is  sufficient  and  appropriate  to 
provide a basis for our opinion.

Other Information

Management is responsible for the other information. Other information comprises:

– the  information  included  in  Management’s  Discussion  and  Analysis  filed  with  the

relevant Canadian Securities Commissions; and

– information,  other  than  the  financial  statements  and  the  auditors’  report  thereon,

included in a document likely to be entitled “Annual Report”.

Our opinion on the financial statements does not cover the other information and we do 
not and will not express any form of assurance conclusion thereon. 

In connection  with  our audit  of the financial statements, our responsibility  is to read the 
other information identified above and, in doing so, consider whether the other information 
is materially inconsistent  with the financial statements or our knowledge  obtained in the 
audit and remain alert for indications that the other information appears to be materially 
misstated.

We obtained the information included in Management’s Discussion and Analysis filed with 
the relevant Canadian Securities Commissions as at the date of this auditors’ report.   If, 
based on the work we have performed on this other information, we conclude that there is 
a material misstatement of this other information, we are required to report that fact in the 
auditors’ report.  We have nothing to report in this regard.

The  information,  other  than  the  financial  statements  and  the  auditors’  report  thereon, 
included  in  a  document  likely  to  be  entitled  “Annual  Report”  is  expected  to  be  made 
available to us after the date of this auditors’ report.  If, based on the work we will perform 
on this other information, we conclude that there is a material misstatement of this other 
information, we are required to report that fact to those charged with governance.   

Responsibilities of Management and Those Charged with Governance 
for the Financial Statements

Management  is  responsible  for  the  preparation  and  fair  presentation  of  the  financial 
statements in accordance with International Financial Reporting Standards, and for such 
internal  control  as  management  determines  is  necessary  to  enable  the  preparation  of 
financial statements that are free from material misstatement, whether due to fraud or error.

In  preparing  the  financial  statements,  management  is  responsible  for  assessing  the 
Company’s ability to continue as a going concern, disclosing as applicable, matters related 
to  going  concern  and  using  the  going  concern  basis  of  accounting  unless management 
either  intends  to  liquidate  the  Company or  to  cease  operations,  or  has  no  realistic 
alternative but to do so.

Those charged with governance are responsible for overseeing the Company‘s financial 
reporting process. 

ERO COPPER | 2019 ANNUAL REPORT | 42

Auditors’ Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the financial statements 
as a whole are free from material misstatement, whether due to fraud or error, and to issue 
an auditors’ report that includes our opinion. 

Reasonable assurance is a high level of assurance, but is not a guarantee that an audit 
conducted in accordance with Canadian generally accepted auditing standards will always 
detect a material misstatement when it exists. 

Misstatements can arise from fraud or error and are considered material if, individually or 
in the aggregate, they could reasonably be expected to influence the economic decisions 
of users taken on the basis of the financial statements.

As part of an audit in accordance with Canadian generally accepted auditing standards, 
we exercise professional judgment and maintain  professional skepticism throughout the 
audit. 

We also:

– Identify  and  assess  the  risks  of  material  misstatement  of  the  financial  statements,
whether due to fraud or error, design and perform audit procedures responsive to those
risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for
our opinion.

The risk of not detecting a material misstatement resulting from fraud is higher than for
one resulting from error, as fraud may involve collusion, forgery, intentional omissions,
misrepresentations, or the override of internal control.

– Obtain an understanding of internal control relevant to the audit in order to design audit
procedures  that  are  appropriate  in  the  circumstances,  but  not  for  the  purpose  of
expressing an opinion on the effectiveness of the Company's internal control.

– Evaluate the appropriateness of accounting policies used and the reasonableness of

accounting estimates and related disclosures made by management.

– Conclude on the appropriateness of management's use of the going concern basis of
accounting and, based on the audit evidence obtained, whether a material uncertainty
exists related to events or conditions that may cast significant doubt on the Company's
ability to continue as a going concern. If we conclude that a material uncertainty exists,
we are required to draw attention in our auditors’ report to the related disclosures in
the financial statements or, if such disclosures are inadequate, to modify our opinion.
Our  conclusions  are  based  on  the  audit  evidence  obtained  up  to  the  date  of  our
auditors’  report.  However,  future  events  or  conditions  may  cause  the Company to
cease to continue as a going concern.

– Evaluate  the  overall  presentation,  structure  and  content  of  the  financial  statements,
including  the  disclosures,  and  whether  the  financial  statements  represents  the
underlying transactions and events in a manner that achieves fair presentation.

– Communicate with those charged  with governance regarding, among other matters,
the planned scope and timing of the audit and significant audit findings, including any
significant deficiencies in internal control that we identify during our audit.

ERO COPPER | 2019 ANNUAL REPORT | 43

– Provide those charged with governance with a statement that we have complied with
relevant ethical requirements regarding independence, and communicate with them all
relationships  and  other  matters  that  may  reasonably  be  thought  to  bear  on  our
independence, and where applicable, related safeguards.

– Obtain sufficient appropriate audit evidence regarding the financial information of the
entities or business activities within the group Company to express an opinion on the
financial  statements.  We  are  responsible 
the  direction,  supervision  and
performance of the group audit. We remain solely responsible for our audit opinion.

mining concession covering an area of 620 ha, where all gold mining and processing activities occur.   

2.  Basis of Preparation 

a)  Statement of Compliance 

These  consolidated  financial  statements  have  been  prepared  in  accordance  with  International  Financial 
Reporting  Standards  (“IFRS”)  as  issued  by  the  International  Accounting  Standards  Board  (“IASB”)  and 
interpretations of the International Financial Reporting Interpretations Committee. 

These consolidated financial statements were authorized for issue by the Board of Directors of the Company 
(the “Board”) on March 12, 2020. 

b)  Basis of Presentation and Principles of Consolidation 

These consolidated financial statements have been prepared on a historical cost basis except for fair-value 
through-profit-or-loss and derivative financial instruments, which are measured at fair value. 

These  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  subsidiaries.  
Subsidiaries are entities controlled by the Company.  Control over a subsidiary is defined to exist when the 
Company is exposed to variable returns from involvement with an investee and has the ability to affect the 
returns through power over the investee.  All intercompany balances and transactions are eliminated upon 
consolidation.   

The  Company  applies  the  acquisition  method  to  account  for  business  combinations.  The  consideration 
transferred by the Company to obtain control of a subsidiary is calculated as the sum of the acquisition-date 
fair values of assets transferred, liabilities assumed and the equity interests issued by the Company, which 
includes  the  fair  value  of  any  asset  or  liability  arising  from  a  contingent  consideration  arrangement. 
Acquisition costs are expensed as incurred. 

The  Company  recognizes  identifiable  assets  acquired  and  liabilities  assumed  in  a  business  combination 
regardless of whether they have been previously recognized in the acquiree’s financial statements prior to 

ERO COPPER | 2019 ANNUAL REPORT | 49 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

the acquisition. Assets acquired and liabilities assumed are generally measured at their acquisition-date fair 
values. 

Goodwill arising from acquisitions is the excess of the sum of a) fair value of consideration transferred, b) 
the recognized amount of any non-controlling interest in the acquiree and c) acquisition-date fair value of 
any existing equity interest in the acquiree, over the acquisition-date fair values of identifiable net assets. If 
the  fair  values  of  identifiable  net  assets  exceed  the  sum  calculated  above,  the  excess  amount  would  be 
recognized in profit or loss immediately.   

Since the Company does not own 100% of its interests in MCSA and NX Gold, the interest attributable to 
non-controlling  shareholders  is  reflected  in  non-controlling  interests.    Adjustments  to  non-controlling 
interests that do not involve the loss of control are accounted for as equity transactions and adjustments are 
based on a proportionate amount of the net assets of the subsidiary.   

c) Foreign Currency Translation

The functional currency and presentation currency of the Company is the US dollar. The monetary assets and 
liabilities of the Company that are denominated in foreign currencies are translated at the rate of exchange
at  the  statement  of  financial  position  date  while  non-monetary  assets  and  liabilities  are  translated  at
historical rates.  Revenues and expenses are translated at the exchange rates approximating those in effect
on the date of the transactions.  Exchange gains and losses arising on translation are included in profit or
loss.

The functional currency of MCSA and NX Gold is the Brazilian Real (“BRL”).  The assets and liabilities of MCSA
and  NX  Gold  are  translated  into  the  US  dollar  presentation  currency  using  the  rate  of  exchange  at  the
statement  of  financial  position  date  while  revenues  and  expenses  are  translated  at  the  exchange  rates
approximating  those  in  effect  on  the  date  of  the  transactions.    Exchange  gains  and  losses  arising  on
translation are included in a separate component of shareholders’ equity.

d) Use of Estimates and Judgments

In preparing these financial statements, management has made judgments, estimates and assumptions that
affect  the  application  of  the  Company’s  accounting  policies  and  the  reported  amounts  of  the  assets,
liabilities, revenues and expenses.  Actual results may differ from these estimates.

The estimates and assumptions are reviewed on an ongoing basis.  Revisions to estimates are recognized
prospectively.

Critical Judgments

Functional currency

The functional currency of the Company and each of its subsidiaries is the currency of the primary economic
environment in which the entities operate.  The Company has determined that the functional currency for
the  Company  is  the  US  dollar  while  the  functional  currency  for  MCSA  and  NX  Gold  is  the  Brazilian  Real.
Assessment  of  functional  currency  involves  certain  judgements  to  determine  the  primary  economic
environment and the Company reconsiders the functional currency of its entities if there is a change in events
and conditions which determined the primary economic environment.

(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

Legal claims and contingent liabilities 

The recognition of legal provisions and contingent liabilities involves the assessment of claims made against 
the Company and each of its subsidiaries.  The recognition of a legal provision, or disclosure of a contingent 
liability, involves certain judgements to determine the probability of whether a cash outflow will occur.  In 
making this judgment, management has assessed various criteria and also relies on the opinions of its legal 
advisers to assist in making this assessment. 

Key Sources of Estimation Uncertainty 

The preparation of financial statements in conformity with IFRS requires management to make estimates 
and assumptions that affect the reported amounts of assets and liabilities and the disclosure of assets and 
liabilities at the date of the consolidated financial statements and the reported amounts of expenses during 
the  reporting  periods.  Actual  results  could  differ  from  those  estimates  and  such  differences  could  be 
significant.  Significant  estimates  made  by  management  affecting  the  consolidated  financial  statements 
include:  

Impairment of mineral, property, plant and equipment 

The  Company evaluates each asset or cash generating unit every reporting period to determine  whether 
there are any indications of impairment. If any such indication exists, which is often judgmental, a formal 
estimate of recoverable amount is performed and an impairment loss is recognized to the extent that the 
carrying amount exceeds the recoverable amount. The recoverable amount of an asset or cash generating 
group of assets is measured at the higher of fair value less costs to sell and value in use. The evaluation of 
asset  carrying  values  for  indications  of  impairment  includes  consideration  of  both  external  and  internal 
sources of information, including such factors as market and economic conditions, production budgets and 
forecasts, and life-of-mine estimates. 

When required, the determination of fair value and value in use requires management to make estimates 
and assumptions about expected production, sales volumes, commodity prices, mineral reserves, operating 
costs, closure and rehabilitation costs and future capital expenditures. The estimates and assumptions are 
subject to risk and uncertainty; hence, there is the possibility that changes in circumstances will alter these 
projections, which may impact the recoverable amount of the assets. In such circumstances, some or all of 
the carrying value of the assets may be further impaired or the impairment charge reduced with the impact 
recorded in profit or loss. 

Mineral reserve and resource estimates including life of mine plan 

The  Company  estimates  its  mineral  reserves  and  mineral  resources  based  on  information  compiled  by 
competent individuals.  Mineral reserves are used in the calculation of depreciation, impairment assessments 
and for forecasting the timing of payment of mine closure and rehabilitation costs. 

There are numerous uncertainties inherent in estimating mineral reserves, and assumptions that are valid at 
the time of estimation may change significantly when new information becomes available.  Changes in the 
estimation methodology, forecasted prices of commodities, exchange rates, production costs or recovery 
rates  may  change  the  economic  status  of  mineral  reserves  and  may,  ultimately,  result  in  changes  in  the 
mineral reserves. 

The carrying amounts of the Company’s mineral properties, plant and equipment are depleted in part based 
on recoverable mineral reserve tonnes processed, depending on the use of the asset.  Changes to estimates 
of recoverable quantities of metals, mineral reserve tonnes and depletable costs, including changes resulting 

ERO COPPER | 2019 ANNUAL REPORT | 51 

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

from revisions to the Company’s mine plans and changes in metals prices forecasts, can result in a change to 
future depreciation and depletion rates and may result in impairment charges. 

Mine closure and rehabilitation costs 

Significant  estimates  and  assumptions  are  made  in  determining  the  provision  for  mine  closure  and 
rehabilitation  as  there  are  numerous  factors  that  will  affect  the  ultimate  liability  payable.    These  factors 
include estimation of the extent and cost of rehabilitation activities, timing of future cash flows, discount 
rates, inflation rate, and regulatory requirements. 

Changes in the above factors can result in a change to the provision recognized by the Company.  Changes 
to mine closure and rehabilitation costs are recorded with a corresponding change to the carrying amounts 
of related mineral properties, plant and equipment.  Adjustments to the carrying amounts of related mineral 
properties, plant and equipment can result in a change to future depreciation and depletion expense. 

Significant assumptions used to determine mine closure and rehabilitation costs are included in Note 11(a).  

Inventory 

The net recoverable value of stockpile inventory and production in work in progress inventory is based on 
the  quantity  of  recoverable  metal  inventory  which  is  an  estimate  based  on  the  tons  of  ore  added  and 
removed from the process, expected grade and recovery rates. The quantity of recoverable metal in finished 
concentrate inventory is an estimate based on initial weights and assay results.  The net recoverable value 
of  these  inventories  also  requires  estimates  of  expected  selling  prices  and,  where  applicable,  costs  to 
complete. 

Income taxes 

The  determination  of  the  Company’s  tax  expense  for  the  period  and  deferred  tax  assets  and  liabilities 
involves significant estimation and judgement by management. In determining these amounts, management 
interprets  tax  legislation  in  a  variety  of  jurisdictions  and  makes  estimates  of  the  expected  timing  of  the 
reversal of deferred tax assets and liabilities. Management also makes estimates of future earnings, which 
affect the extent to which potential future tax benefits may be used. The Company is subject to assessments 
by various taxation authorities, which may interpret legislation differently. These differences may affect the 
final amount or the timing of the payment of taxes. The Company provides for such differences where known 
based on management’s best estimate of the probable outcome of these matters. 

e)  Changes in Accounting Standards Adopted During the Year  

The following new and amended IFRS pronouncements were adopted effective January 1, 2019: 

IFRS 16 Leases 

IFRS 16 introduces a single, on-balance sheet accounting model for lessees.  As a result, the Company, as a 
lessee,  has  recognized  right-of-use  assets  representing  its  rights  to  use  the  underlying  assets  and  lease 
liabilities representing its obligation to make lease payments.  The Company may elect to not apply IFRS 16 
to leases with a term of less than 12 months, which election is made by underlying class of assets to which 
the right of use asset relates, or leases where the underlying asset is of low value, which election is made on 
an asset by asset basis. Lessor accounting remains similar to previous accounting policies. 

Previously, the Company determined at contract inception whether an arrangement was or contained a lease 
under IFRIC 4, Determining Whether an Arrangement contains a Lease.  The Company now assesses whether 

ERO COPPER | 2019 ANNUAL REPORT | 52 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

a contract is or contains a lease based on the new definition of a lease.  Under IFRS 16, a contract is, or 
contains, a lease if the contract conveys a right to control the use of an identified asset for a period of time 
in exchange for consideration.  

The Company’s accounting policy in Note 3(m) has been updated to reflect the Company’s new accounting 
policies under IFRS 16. 

Transition 

The  Company  adopted  IFRS  16  using  the  modified  retrospective  approach.  Accordingly,  the  comparative 
information presented for 2018 has not been restated. 

On transition to IFRS 16, the Company elected to apply the practical expedient to grandfather the assessment 
of which transactions are leases.  Accordingly, IFRS 16 was applied only to contracts that were previously 
identified as leases. Contracts that were not identified as leases under IAS 17 and IFRIC 4 were not reassessed. 
Therefore, the definition of a lease under IFRS 16 has been applied only to contracts entered into or changed 
on or after January 1, 2019.  

As a lessee, the Company previously classified leases as operating or finance leases based on its assessment 
of whether the lease transferred substantially all of the risks and rewards of ownership.  Under IFRS 16, the 
Company  recognizes  right-of-use  assets  and  lease  liabilities  for  most  leases.    However,  the  Company  has 
elected not to recognize right-of-use assets and lease liabilities for some leases of low-value assets and with 
a term of less than 12 months.  The Company recognizes the lease payments associated with these leases as 
an expense on a straight-line basis over the lease term.  

The  Company  leases  various assets  including  equipment, offices  and  properties  that  had  previously been 
classified as operating leases under IAS 17.  On transition lease liabilities for these leases were measured at 
the present value of remaining lease payments, discounted at the Company’s or subsidiary’s incremental 
borrowing rate as of January 1, 2019. The average incremental borrowing rate at January 1, 2019 used for 
base calculations was 10%. The Company elected to measure the right-of-use assets at an amount equal to 
the lease liability. 

The Company used the following practical expedients when applying IFRS 16 to leases previously classified 
as operating leases under IAS 17: 

•

•

•

Applied the exemption not to recognize right-of-use assets and liabilities for leases with less than
12 months of lease term.
Applied a single discount rate to a portfolio of leases with reasonably similar characteristics (such as 
leases with a similar remaining lease term for a similar class of underlying asset in a similar economic 
environment).
Used  hindsight  when  determining  the  lease  term  if  the  contract  contains  options  to  extend  or
terminate the lease.

The  Company  did  not  have  any  leases  classified  as  finance  leases  under  IAS  17  on  the  adoption  date. 

The Company presents right-of-use assets in mineral, property, plant and equipment in the statement of 
financial position, the same line item as it presents underlying assets of the same nature that it owns.  The 
Company presents lease liabilities as a separate line item on the statement of financial position.

IFRIC 23 – Uncertainty over Income Tax Treatments 

The  Company  has  adopted  IFRIC  Interpretation  23  (“Interpretation  23”)  –  Uncertainty  over  Income  Tax 
Treatments from January 1, 2019. The Interpretation provides guidance on the accounting for current and 
deferred tax liabilities and assets in circumstances in which there is uncertainty over income tax treatments. 
There is no material impact on the financial statements from the adoption of Interpretation 23. 

3. Significant Accounting Policies

a) Revenue

Revenue  is  generated  from  the  sale  of  sale  of  metals  in  concentrate  and  gold  doré.  The  Company’s
performance obligations relate primarily to the delivery of the concentrate or gold doré to customers, with
each shipment representing a separate performance obligation.

Revenue from the sale of metals in concentrate and gold doré is recognized at the point the customer obtains 
control of the product. Control is transferred when title has passed to the purchaser, the product is physically 
delivered to the customer, the customer controls the risks and rewards of ownership and the Company has
a present right to payment for the product which is generally when the concentrate or ore is delivered to a
location designated by the customer.

The sales amount is typically based on quoted market and contractual prices which are fixed at the time the
shipment  is  received  at  the  customers’  premises.    In  certain  circumstances  the  sales  price  of  metals  in
concentrate may be determined in a period subsequent to the date of sale (provisionally priced sales) based
on the terms of specific copper concentrate contracts.  Provisionally priced sales are recognized based on an
estimate of metal contained using forward market prices corresponding with the expected date that final
sales  prices  will  be  fixed.    The  period  between  provisional  pricing  and  final  settlement  can  be  up  to  one
month.  The settlement receivable is recorded at fair value each reporting period by reference to forward
market  prices  until  the  date of  final  pricing,  with  the  changes  in  fair  value  recorded  as  an  adjustment  to
revenue.

b) Tax Incentives

The Company receives certain tax incentives in Brazil.  These tax incentives are recognized in profit or loss in
the  period  the  incentives  are  received  or  receivable  and  recorded  against  the  expenditure  that  they  are
intended to compensate.

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

c)  Finance Income and Finance Expense 

Finance income includes interest on cash and cash equivalents, restricted cash and financial investments, 
and gains related to changes in the fair value of financial assets measured at fair value through profit. Interest 
income is recognized as it accrues in profit or loss, using the effective interest method. 

Finance  expense  comprise  interest  expense  on  loans  and  borrowings,  unwinding  of  the  discount  on 
provisions and leases, commitment fees and losses related to changes in the fair value of financial assets 
measured  at  fair  value  through  profit  or  loss.  Borrowing  costs  that  are  not  directly  attributable  to  the 
acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective 
interest method.   

d)  Employee Benefits 

Short-term employee benefit obligations are recognized as personnel expenses as the corresponding service 
is provided. Liabilities are recognized at the amount that is expected to be paid if the Company has a present 
legal or constructive obligation to pay that amount based on past services rendered by the employee, and 
the obligation can be estimated reliably.  There are no long-term employee benefit plans. 

e)  Taxation 

Income tax expense comprises current and deferred tax.  Current income tax is the expected tax payable or 
receivable on the taxable income or loss for the year using tax rates enacted or substantively enacted at the 
reporting date.   

Deferred  income  tax  is  recognized  in  respect  of  temporary  differences  between  the  carrying  amounts  of 
assets and liabilities for financial reporting purposes and the amounts used for taxation purposes.  Deferred 
income tax is measured at the tax rates that are expected to be applied to temporary differences when they 
reverse,  based  on  the  tax  laws  that  have  been  enacted  or  substantively  enacted  at  the  reporting  date.  
Deferred income tax assets and liabilities are offset if there is a legally enforceable right to offset current tax 
liabilities and assets, and they relate to income taxes levied by the same tax authority on the same taxable 
entity.   Deferred income tax is not recognized for the initial recognition of assets or liabilities in a transaction 
that is not a business combination and that effects neither accounting nor taxable income or loss, differences 
related  to  investments  in  subsidiaries  to  the  extent  that  it  is  probable  that  they  will  not  reverse  in  the 
foreseeable future and taxable differences arising from the initial recognition of goodwill. 

A  deferred  income  tax  asset  is  recognized  for  unused  tax  losses,  tax  credits  and  deductible  temporary 
differences, to the extent that it is probable that future taxable profits will be available against which they 
can be utilized.  Deferred income tax assets are reviewed at each reporting date and are reduced to the 
extent that it is no longer probable that the related tax benefit will be realized. 

f) 

Inventories 

Inventories are measured at the lower of cost and net realizable value. The cost of consumable inventory is 
determined on a weighted average acquisition cost basis.  Cost of stockpile inventory, products in progress 
and finished goods is determined based on a weighted average production cost basis and includes the cost 
of mining and processing ore including direct labour and materials; depreciation and amortization; and an 
appropriate share of production overheads based on normal operating capacity.  

Net realizable value of stockpile inventory, products in progress and finished goods is the estimated selling 
price in the ordinary course of business, less estimated completion costs and selling expenses. 

ERO COPPER | 2019 ANNUAL REPORT | 55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

Provisions for low turnover or obsolete supplies and consumables inventory are established by management 
as deemed necessary. 

g) Mineral, Property, Plant and Equipment

Mineral, property, plant and equipment is measured at acquisition or construction cost, including capitalized
borrowing costs, less accumulated depreciation and accumulated impairment losses.

i) Acquisition and disposal

The cost of mineral, property, plant and equipment include expenditures directly attributable to an asset’s 
acquisition. The cost of assets constructed by Company includes the cost of materials and direct labor, any 
other costs to bring the asset in the place and conditions required to be operated in the manner intended by 
management, costs of disassembly and restoration of the site and borrowing costs on qualifying assets. 

When parts of mineral, property, plant and equipment have different useful lives, they are accounted for as 
separate items (major components) of mineral, property, plant and equipment. 

Gains and losses on disposal of mineral, property, plant and equipment are determined by comparing the 
proceeds from disposal with the carrying amount of equipment and are recognized net within other income.  

ii) Subsequent costs

The cost of replacing plant and equipment is recognized in the carrying amount of the item if it is probable 
that the future economic benefits embodied within the item will flow to the Company and its cost can be 
measured reliably.  The carrying amount of the replaced item is derecognized.  The costs of the day-to-day 
servicing of equipment are included in profit or loss.   

iii) Development and construction in progress

When  economically  viable  mineral  reserves  have  been  determined  and  the  decision  to  proceed  with 
development has been approved, exploration and evaluation assets are first assessed for impairment, then 
reclassified to construction-in-progress or mineral properties. The expenditures related to development and 
construction are capitalized as construction-in-progress and are included within mineral, property, plant and 
equipment. Costs associated with the commissioning of new assets incurred before they are operating in the 
way intended by management, including directly attributable costs of testing, are capitalized. Construction-
in-progress includes the purchase price and any costs directly attributable to bringing the asset to the location 
and condition necessary for its intended use including advances on long-lead items.  Construction-in-progress 
is not depreciated.   

Once  the  asset  is  operating  in  the  way  intended  by  management,  construction-in-progress  costs  are 
reclassified to mineral properties or plant and equipment.  

Pre-production  costs  of  removing  overburden  to  access  ore  in  the  open  pit  mines  and  developing  access 
headings  in  the  underground  mines  are  capitalized  as  pre-production  stripping  or  development  costs 
respectively and are included within mineral, property, plant and equipment. Revenues earned during pre-
production periods are also capitalized.  

ERO COPPER | 2019 ANNUAL REPORT | 56 

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

iv) Mineral properties

Mineral properties consist of the cost of acquiring and developing mineral properties.  Once in production, 
mineral properties are amortized on a units-of-production basis over the component of the ore body to which 
they relate. 

v) Stripping costs and development in the production phase

Where  open  pit  production  stripping  or  underground  development  activities  do  not  result  in  inventory 
produced, but does provide improved access to the ore body, the costs are classified as mineral properties 
when these activities meet all of the following criteria: (1) it is probable that the future economic benefit 
associated with the activity will flow to the Company; (2) the Company can estimate the mineral reserve of 
the ore body for which access has been improved; and (3) the costs relating to the activity associated with 
that mineral reserve can be measured reliably.  

For underground mines, costs incurred to access a mineral reserve of the ore body are capitalized to mineral 
properties or construction-in-progress and are depreciated on a units-of-production basis over the expected 
useful life of the identified mineral reserve of the ore body to which access has been improved as a result of 
the  development  activity.    For  open  pit  mines,  stripping  costs  are  capitalized  to  mineral  properties  or 
construction-in-progress  until  an  average  stripping  ratio  is  achieved  (waste/ore)  for  the  mine.    After  the 
stripping ratio is achieved, all stripping costs are classified as production costs.  The capitalized stripping costs 
are depreciated over the related mineral reserves accessed by the stripping activity. 

vi) Mine closure and rehabilitation costs

The  Company’s  provision  for  mine  closure  and  rehabilitation  liabilities  represents  management’s  best 
estimate  of  the  present  value  of  the  future  cash  outflows  required  to  settle  estimated  reclamation  and 
closure costs at the end of a mine’s life. The provision reflects estimates of future costs, inflation, movements 
in  foreign  exchange  rates  and  assumptions  of  risks  associated  with  the  future  cash  outflows,  and  the 
applicable risk-free interest rates for discounting the future cash outflows. Changes in the above factors can 
result in a change to the provision recognized by the Company. 

vii) Depreciation

Items of mineral, property, plant and equipment are depreciated on a straight-line method based on the 
estimated economic useful life of each component as follows: 

Buildings 
Mining equipment 
Mobile equipment & other assets 
Mineral properties 
Mine closure and rehabilitation costs 

Right of use assets 

Up to 25 years 
4 years 
5 years 
Units of production 
Units of production or 
period until remediation 
Shorter of the term of 
lease and life of asset 

The depletion of mineral, properties and mine closure and rehabilitation costs is determined based on the 
ratio of tons of copper/kg of gold contained in the ore mined and total proven and probable mineral reserve 
tonnes of contained copper/kg of contained gold.   

Depreciation methods, useful lives and residual values are reviewed at each financial year end and adjusted 
if appropriate.

Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

h)  Exploration and Evaluation Assets 

Exploration and evaluation costs relate to the initial search for a mineral deposit, the cost of acquisition of a 
mineral property interest or exploration rights and the subsequent evaluation to determine the economic 
potential  of  the  mineral  deposit.  The  exploration  and  evaluation  stage  commences  when  the  Company 
obtains the legal right or license to begin exploration and subsequently exploration and evaluation expenses 
are capitalized as exploration and evaluation assets.  Costs incurred prior to the Company obtaining the legal 
rights are expensed. 

When  the  exploration  and  evaluation  of  a  mineral  property  indicates  that  development  of  the  mineral 
property  is  technically  and  commercially  feasible,  the  future  economic  benefits  are  probable,  and  the 
Company has the intention and sufficient resources to complete the development and use or sell the asset, 
the  related  costs  are  transferred  from  exploration  and  evaluation  assets  to  mineral  property,  plant  and 
equipment. 

Management reviews the carrying value of capitalized exploration costs for indicators that the carrying value 
is impaired at least annually and when facts and circumstances suggest that the carrying amount may exceed 
the  recoverable  amount.  The  review  is  based  on  the  Company’s  intentions  for  further  exploration  and 
development of the undeveloped property, results of drilling, commodity prices and other economic and 
geological factors. Subsequent recovery of the resulting carrying value depends on successful development 
or sale of the undeveloped project. If a property does not prove viable, all non-recoverable costs associated 
with the project, net of any previous impairment provisions, are written off. 

i)  Financial Instruments  

Non-derivative financial assets 

The  Company  classifies  its  financial  assets  in  the  following  categories:  at  fair  value  through  profit  or  loss 
(“FVTPL”),  at  fair  value  through  other  comprehensive  income  (“FVTOCI”)  or  at  amortized  cost.  The 
classification depends on the purpose for which the financial assets were acquired.  Management determines 
the  classification  of  its  financial  assets  at  initial  recognition.    Measurement  and  classification  of  financial 
assets is dependent on the Company’s business model for managing the financial assets and the contractual 
cash flow characteristics of the financial asset.  Financial assets are derecognized when they mature or are 
sold, and substantially all the risks and rewards of ownership have been transferred.   

Fair values 

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for 
both financial and non-financial assets and liabilities. 

When measuring the fair value of an asset or liability, the Company uses observable market data, as much as 
possible. Fair values are classified into different levels in a hierarchy based on the inputs used in the valuation 
techniques, as follows: 

• 

• 

• 

Level 1: quoted prices (without adjustments) in active markets for identical assets or liabilities.    

Level 2: inputs other than Level 1 quoted prices, that are observable for the asset or liability, either 
directly (i.e. as prices) or indirectly (i.e. derived from prices).    

Level 3: inputs, for assets or liabilities, that are not based on observable market information (non-
observable inputs).

(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

The Company recognizes transfers between levels of the hierarchy of fair value at the end of the reporting 
period during which the change occurred. 

When applicable, additional information on the assumptions used in the fair value calculations are disclosed 
in the specific notes of the corresponding asset or liability.   

Financial assets at FVTPL 

Financial assets carried at FVTPL are initially recorded at fair value and transaction costs are expensed in the 
income statement. Realized and unrealized gains and losses arising from changes in the fair value of the 
financial asset held at FVTPL are included in profit or loss in the period in which they arise. Derivatives are 
also categorized as FVTPL unless they are designated as hedges. 

Financial assets at FVTOCI 

Investments  in  equity  instruments  at  FVTOCI  are  initially  recognized  at  fair  value  plus  transaction  costs. 
Subsequently  they  are  measured  at  fair  value,  with  gains  and  losses  arising  from  changes  in  fair  value 
recognized in other comprehensive income. Gains or losses on financial assets classified as FVTOCI remain 
within accumulated other comprehensive income following the derecognition of the investment. 

Financial assets at amortized cost 

Financial assets at amortized cost are initially recognized at fair value and subsequently carried at amortized 
cost less any impairment. They are classified as current assets or non-current assets based on their maturity 
date. Gains and losses on derecognition of financial assets classified amortized cost are recognized in profit 
or loss. 

Financial liabilities 

Financial  liabilities  are  recognized  initially  at  fair  value,  net  of  transaction  costs  incurred,  and  are 
subsequently measured at amortized cost. Any difference between the amounts originally received, net of 
transaction costs, and the redemption value is recognized in profit and loss over the period to maturity using 
the effective interest method. 

Derivative instruments 

Derivative instruments, including embedded derivatives in executory contracts or financial liability contracts, 
are classified as at FVTPL and, accordingly, are recorded in the statement of financial position at fair value. 
Unrealized gains and losses on derivatives not designated in a hedging relationship are recorded as part of 
the revenue or expense item to which the derivative relates, depending on the nature of the derivative. Fair 
values for derivative instruments are determined using inputs based on market conditions existing at the 
balance sheet date or settlement date of the derivative. Derivatives embedded in non-derivative contracts 
are recognized separately unless they are closely related to the host contract.   

Trade receivables related to provisionally priced sales are measured at fair value with changes recognized in 
profit or loss. 

Compound instruments 

Equity components of compound instruments, such as convertible debt, are separated from the debt host 
contract  using  the  residual  method.  The  Company  determines  the  fair  value  of  the  debt  component  by 

ERO COPPER | 2019 ANNUAL REPORT | 59 

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

discounting the expected principal and interest payments using an appropriate discount rate reflective of 
debt instruments with similar risks but without the equity component. The difference between the proceeds 
received and the amount assigned to the debt component is allocated to the equity component. 

Share capital 

Common shares are classified as equity.  Incremental costs directly attributable to the issuance of common 
shares and share options are recognized as a deduction from equity, net of any tax effects. The Company 
includes  the  value  of  share  purchase  warrants  included  in  the  issuance  of  equity  units,  which  consist  of 
common shares and warrants, in share capital. 

Classification and Measurement Changes 

The Company has assessed the classification and measurement of its financial assets and financial liabilities 
under IFRS 9 in the following table:  

Financial Assets:
Cash, cash equivalents and restricted cash
Trade receivables
Deposits
Other non-current assets - term deposits
Financial Liabilities:
Trade payables
Loans and borrowings
Derivatives

Cash and cash equivalents, restricted cash and deposits 

Cash is comprised of cash on hand and demand deposits.  Cash equivalents, restricted cash and deposits are 
short-term,  highly  liquid  investments  with  original  maturities  of  three  months  or  less  that  are  readily 
convertible to known amounts of cash and which are subject to an insignificant risk of change in fair value.   

Trade receivables  

Trade receivables relate to amounts receivable from sales with fixed or determinable payments that are not 
quoted in an active market.  These receivables are non-interest bearing and are recognized at face amount, 
except  when  fair  value  is  materially  different,  and  are  subsequently  measured  at  amortized  cost.  Trade 
receivables recorded are net of lifetime expected credit losses.  

Other non-current assets – term deposits 

Term deposits are directly related to loan agreements with a Brazilian financial institution which requires the 
establishment  of  a  reserve  fund.    Redemptions  of  financial  investments  are  conditional  on  the  Company 
making the scheduled loan repayments.  These term deposits are classified as, and subsequently measured 
at, amortized cost.  These term deposits are recognized initially at fair value plus any directly attributable 
transaction costs.  Subsequent to initial recognition, they are measured at amortized cost using the effective 
interest method, less any impairment losses.

j)

Impairment

i) Financial assets

The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at 
amortized cost. At each reporting date, the loss allowance for the financial asset is measured at an amount 
equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly 
since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial 
recognition, the loss allowance is measured for the financial asset at an amount equal to twelve months’ 
expected credit losses. For trade receivables the Company applies the simplified approach to providing for 
expected  credit  losses,  which  allows  the  use  of  a  lifetime  expected  loss  provision.  Impairment  losses  on 
financial  assets  carried  at  amortized  cost  are  reversed  in  subsequent  periods  if  the  amount  of  the  loss 
decreases  and  the  decrease  can  be  objectively  related  to  an  event  occurring  after  the  impairment  was 
recognized.    The  expected  lifetime  credit  loss  provision  for  trade  receivables  is  based  on  historical 
counterparty default rates and adjusted for relevant forward-looking information, when required. As the 
Company’s  three  primary  significant  customers  are  considered  to  have  a  low  default  rate  and  historical 
default  rates  are  low,  the  lifetime  expected  credit  loss  allowance  for  trade  receivables  is  nominal  as  at 
December 31, 2019.  Accordingly, the Company did not record a provision for expected credit losses for trade 
receivables.   

ii) Non-Financial assets

At each reporting date the carrying amounts of the Company’s mineral, property, plant and equipment and 
exploration  and  evaluation  assets  are  reviewed  to  determine  whether  there  is  any  indication  that  those 
assets are impaired. If such indication exists, the recoverable amount of the asset is estimated in order to 
determine the extent of the impairment, if any.  The recoverable amount is the higher of fair value less costs 
to sell and value in use, which is the present value of future cash flows expected to be derived from the asset 
or its related cash generating unit.  For purposes of impairment testing, assets are grouped at the lowest 
levels that generate cash inflows from continuing use that are largely independent of the cash inflows of 
other assets or groups of assets (the “cash-generating unit”). 

If the recoverable amount of an asset or cash-generating unit is estimated to be less than its carrying amount, 
the carrying amount of the associated assets are reduced to their recoverable amount and the impairment 
loss is recognized in the profit or loss for the period. 

Impairment losses recognized in prior periods are assessed at each reporting date for any indications that 
the loss has decreased or no longer exists.  An impairment charge is reversed through profit or loss only to 
the extent that the asset’s carrying amount does not exceed the  carrying amount that would have been 
determined, net of any applicable depreciation, if no impairment loss had been recognized.    

k) Provisions

i) Mine closure and rehabilitation provision

The Company records the present value of estimated costs of legal and constructive obligations related to 
mine closure and rehabilitation in the period in which the obligation occurs.  Mine closure and rehabilitation 
activities include facility decommissioning and dismantling; removal and treatment of waste materials; site 
and land rehabilitation, including compliance with and monitoring of environmental regulations; and related 
costs  required  to  perform  this  work  and/or  operate  equipment  designed  to  reduce  or  eliminate 
environmental effects.  The provision is adjusted each period for new disturbances, and changes in regulatory 
requirements, the estimated amount of future cash flows required to discharge the obligation, the timing of 

ERO COPPER | 2019 ANNUAL REPORT | 61 

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

such  cash  flows  and  the  pre-tax  discount  rate  specific  to  the  liability.    The  unwinding  of  the  discount  is 
recognized in profit or loss as a finance expense. 

When the provision is initially recognized, the corresponding cost is capitalized by increasing the carrying 
amount of the related asset and is amortized to profit or loss on a unit-of-production basis.   

ii) Other provisions

Other  provisions  are  recognized,  based  on  a  past  event,  when  the  Company  has  a  legal  or  constructive 
obligation  that  can  be  estimated  reliably,  and  it  is  probable  that  an  economic  mineral  resource  will  be 
required to settle the obligation. Provisions are measured by discounting the expected future cash flows at 
a pre-tax rate that reflects current market assessments of the time value of money and specific risks for the 
liability. The discount is unwound over the period over which the cash flows are expected to be incurred with 
the related expense included in finance expense. 

l) Share-Based Compensation

The grant date fair value of share-based payment awards granted to employees and consultants, including
directors and officers, is recognized as an employee expense, with a corresponding increase in equity, over
the period that the employees unconditionally become entitled to the awards. The amount recognized as an 
expense is adjusted to reflect the number of awards for which the related service and non-market vesting
conditions  are  expected  to  be  performed  or  satisfied  such  that  the  amount  ultimately  recognized  as  an
expense  is  based  on  the  number  of  awards  that  meet  the  related  service  and  non-market  performance
conditions at the vesting date.

m) Leases

A contract is or contains a lease when the contract conveys a right to control the use of an identified asset
for a period of time in exchange for consideration.

The Company recognizes a right-of-use asset and a lease liability at the lease commencement date.  The right-
of-use asset is initially measured at cost, and subsequently at cost less any accumulated depreciation and
impairment losses, and adjusted for certain re-measurements of the lease liability. The cost of the right-of-
use asset includes the amount of the initial measurement of the lease liability, any lease payments made at
or  before  the  commencement  date,  less  any  lease  incentives  received,  any  initial  direct  costs;  and  if
applicable, an estimate of costs to be incurred by the Company in dismantling and removing the underlying
asset, restoring the site on which it is located or restoring the underlying asset to the condition required by
the terms and conditions of the lease.

The lease liability is initially measured at the present value of the lease payments that are not paid at the
commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily
determined, the Company’s incremental borrowing rate. The incremental borrowing rate reflects the rate of
interest that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value
in  a  similar  economic  environment  with  similar  terms  and  conditions.  Generally,  the  Company  uses  its
incremental borrowing rate as the discount rate.

The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease
payments made.  It is remeasured when there is a change in future lease payments arising from a change in
an index or rate, a change in the estimate of the amount expected to be payable under a residual value
guarantee,  or  as  appropriate,  changes  in  the  assessment  of  whether  a  purchase  or  extension  option  is
reasonably certain to be exercised or a termination option is reasonably certain not to be exercised.

ERO COPPER | 2019 ANNUAL REPORT | 62 

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

The Company does not recognize right-of-use assets and lease liabilities for leases of low-value assets and 
leases with lease terms that are less than 12 months. Lease payments associated with these leases are instead 
recognized as an expense over the lease term on either a straight-line basis, or another systematic basis if 
more representative of the pattern of benefit.   

The Company has applied judgement to determine the lease term for some lease contracts in which it is a 
lessee  that  include  renewal  options.    The  assessment  of  whether  the  Company  is  reasonably  certain  to 
exercise such options impacts the lease term, which significantly affects the amount of lease liabilities and 
right-of-use assets recognized. 

n) Income (Loss) per Share

Basic income (loss) per share is calculated by dividing the profit or loss attributable to common shareholders
of the Company by the weighted average number of common shares outstanding during the period.  Diluted
income (loss) per common share is calculated by adjusting the weighted average number of common shares
outstanding for the effect of conversion of all potentially dilutive share equivalents, such as stock options
and warrants, and assumes that the receipt of proceeds upon exercise of the options are used to repurchase
common shares at the average market price during the period.  The net effect of the shares issued less the
shares  assumed  to  be  repurchased  is  added  to  the  basic  weighted  average  shares  outstanding.    For
convertible instruments, the common shares to be included in the diluted per share calculation assumes that 
the instrument is converted at the beginning of the period (or the issue date if later). For Share Units (as
defined herein, see note 12(b)), the common shares to be included in the diluted per share calculation is
based on the number of shares that would be issuable if the reporting date were the end of the vesting
period.  The profit or loss attributable to common shareholders is adjusted to eliminate related interest costs
of dilutive securities recognized in profit or loss for the period.

income taxes and taxes on future sales (note 18).

6. Mineral, Property, Plant and Equipment (continued)

Of the $118.9 million in mineral, property, plant and equipment purchases during the year ended December 31, 
2019, $8.6 million was obtained through financing arrangements directly from equipment suppliers. 

Certain equipment is secured for the equipment finance loans (note 9). 

Included in mineral, property, plant and equipment is $7.3 million (December 31, 2018 - $10.4 million) related to 
the value of mineral resources beyond proven and probable reserves not currently being amortized.  During the 
year ended December 31, 2019, $3.1 million (year ended December 31, 2018 - $8.2 million) was transferred from 
mineral resources to amortizable mineral reserves as a result of an update to MCSA’s proven and probable reserves 
during the year.  In addition, $52.7 million (December 31, 2018 - $42.1 million) related to projects in progress are 
not currently being amortized.

In December 2018, the Company replaced the $50 million senior secured non-revolving credit facility completed on 
December 29, 2017 with a new $130 million facility from a syndicate of Canadian financial institutions.  The facility 
is comprised of an $80 million senior secured amortizing non-revolving credit facility (“Term Facility”) and a $50 
million senior secured revolving term credit facility (“Revolving Credit Facility”) (collectively the “Facilities”).  The 
Term Facility has a 5-year term with equal quarterly principal payments of $6.2 million beginning on December 13, 
2020, while the Revolving Credit Facility is payable at maturity on December 13, 2022.  The Facilities bear interest 
on a sliding scale at a rate of LIBOR plus 2.75% to 4.75% depending on the Company’s consolidated leverage ratio 
at the time.  The Company incurred transaction costs associated with the Facilities of $2.3 million which have been 
included in the carrying value of the Facilities and are being amortized using an effective interest rate of 5.64%.  The 
settlement of the previous $50 million senior secured non-revolving credit facility resulted in a loss on settlement 
of $1.8 million.   

In January 2019, the Company entered into an interest rate swap transaction with a Canadian financial institution 
whereby the floating LIBOR interest on a notional amount of $65 million was swapped for a fixed interest rate of 
2.69%.  This interest rate swap transaction is in effect for the term of the Term Facility, with the notional amount 
reduced as principal payments are made.  Settlements are being made on a quarterly basis.

Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

During the second quarter of 2019, the Company refinanced a loan held by the Company’s subsidiary, MCSA, by 
extending  the  Revolving  Credit  Facility.    The  credit  limit  of  the  Revolving  Credit  Facility  was  increased  by  $20.0 
million to $70.0 million.  All other terms of the Facilities remained unchanged. Upon completion of the amendment, 
the Company drew $11.0 million to repay certain of its bank loans held by MCSA.  As at December 31, 2019, the

The Company’s provision for mine closure and rehabilitation consists of costs accrued based on the current best 
estimate of mine closure and reclamation activities that will be required upon completion of mining. The Company’s 
provision for future site closure and reclamation costs is based on the level of known disturbance at the reporting 
date, known legal requirements and cost estimates prepared by a third-party specialist.  

Management used a pre-tax discount rates in the range of 4.34% - 6.5% (2018 – 6.5%) and an inflation factor in the 
range of 3.5% –  3.75% (2018 –  4.2%) in preparing the Company’s provision for mine closure and rehabilitation. 
Although the ultimate amount to be incurred is uncertain, based on development, legal requirements and estimated 
costs  as  at  December  31,  2019,  the  undiscounted  inflation-adjusted  liability  for  provision  for  mine  closure  and 
rehabilitation is estimated to be approximately $45.7 million (2018 - $48.7 million), of which $36.8 million (2018 - 
$39.1 million) relates to MCSA and $8.9 million (2018 - $9.6 million) relates to NX Gold. The cash expenditures are 
expected to occur over a period of time extending several years after the projected closure, which for both MCSA 
and NX Gold is currently 2026.   

(b) Legal claims

There are various legal actions that are in process against the Company’s Brazilian subsidiaries related to labor, 
civil and tax matters. Based on an analysis of individual judicial and administrative legal claims, the following 
provision has been made for probable losses associated with these claims:

reimbursements, overtime and severance payments.  Of the claims made, the Company has assessed, with the 
assistance of its legal counsel, that the probable loss on such claims is $3.3 million and such amount has been 
accrued.

(ii) Tax claims

The provisions for tax claims relate to tax assessments, interest and penalties resulting from unpaid income and 
social contribution taxes by MCSA.   

In  relation  to  the  above-mentioned  claims  and  those  discussed  in  Note  11(c)  below,  MCSA  and  NX  Gold  were 
required to place a total of $1.2 million in trust as of December 31, 2019 (December 31, 2018 - $1.3 million), which 
is included in other non-current assets on the statement of financial position. 

(c) Contingent liabilities

As of December 31, 2019, based on the opinion of its legal advisers, the Company has not recognized a provision 
for the following claims of MCSA and NX Gold as it is not probable that a cash outflow will occur.

Social security claims relate to potential social security tax payments related to past payments to employees, 
including profit sharing, and payments made to external contractors.  The Company strongly believes, based 
on  precedent  court  case  rulings,  that  part  of  the  claim  will  be  cancelled  after  administrative  and  judicial 
discussions.  The estimated portion of the claim expected to be cancelled of $3.7 million is included in the table 
above.   

(ii) Tax

There are 129 tax claims (2018 – 99 tax claims) against MCSA which were evaluated as possible, but not probable, 
losses by external legal counsel.  The main subjects under discussion for the tax claims involve the validity of tax 
credits used to offset federal taxes.   

(iii) Mining

In  June  2019,  MCSA  was  notified  of  five  administrative  claims  filed  by  the  Nacional  Mining  Agency  regarding 
alleged differences in the calculation of certain sales taxes on mining revenue by MCSA.  The Company, based on 
the opinion of its legal advisors, does not believe such claims will result in a probable cash outflow.

committee’s  recommendations,  may  establish  performance  conditions  for  the  vesting  of  the  Share  Units.  The 
performance conditions may be graduated such that different percentages (which may be greater or lower than 
100%) of the Share  Units in  a grant become vested depending on the satisfaction of one or more performance 
conditions.  Performance conditions may include terms or conditions relating to: (i) the market price of the Shares; 
(ii) the return to holders of shares, with or without reference to other comparable companies; (iii) the financial
performance or results of the Company or its subsidiaries; (iv) the achievement of performance conditions or other
performance criteria relating to the Company or its subsidiaries; (v) any other terms and conditions the Board may
in its sole discretion determine with respect to vesting or the acceleration of vesting; and (vi) the vesting date of
the  Share  Units.    The  Board  may,  in  its  discretion,  subsequent  to  the  grant  of  a  Share  Unit,  waive  any  such
performance condition or determine that it has been satisfied subject to applicable law. Each Share Unit entitles
the holder thereof to receive one common share, without payment of additional consideration, on the redemption
date selected by the Board following the date of vesting of such Share Unit, which will be within 30 days of the date
of vesting, or at a later deferred date, subject to certain exception and restrictions.

On December 31, 2018, 215,288 Share Units were issued and on December 12, 2019, 225,659 Share Units were 
issued to certain officers and employees of the Company pursuant to the Company’s Share Unit Plan.  These Share 
Units will vest three years from the date they were approved for granting by the Board (December 31, 2021 and 
December 12, 2022, respectively) and the number of Share Units that will vest may range from 0% to 200% of the 
number granted, subject to the satisfaction of certain market and non-market performance conditions.  Each vested 
Share Unit entitles the holder thereof to receive on or about the applicable date of vesting of such Share Unit (i) 
one common share; (ii) a cash amount equal to the fair market value of one common share as at the applicable date 
of vesting; or (iii) a combination of (i) and (ii), as determined by the Board in its sole discretion.  The Company 
currently intends to settle these Share Units using common shares.  Accordingly, they are classified as equity settled 
instruments. 

As  at  December  31,  2019,  437,463  Share  Units  have  been  issued  and  are  outstanding  to  certain  officers  and 
employees of the Company pursuant to the Company’s Share Unit Plan.   

For  the  Share  Units  with  non-market  performance  conditions,  the  fair  value  of  the  Share  Units  granted  was 
determined using the share price at the date of grant.  For the Share Units with market performance conditions, 
the fair value of the Share Units granted was determined using a Geometric Brownian Motion model.  Expected 
volatility is estimated by considering historic share price information.  The inputs used in the measurement of fair 
values at grant date of the Share Units issued are the following: 

Expected term (years)
Forfeiture rate
Volatility
Dividend yield

During the year ended December 31, 2019, the Company recorded share-based compensation of $1.0 million (2018 
- $nil) with respect to the Share Units.

Subsequent to December 31, 2019, 1,000 Share Units were issued to certain employees of the Company pursuant 
to the Company’s Share Unit Plan. 

(c) Deferred Share Unit Plan

On December 12, 2019, a Deferred Share Unit Plan (“DSU Plan”) was established by the Board as a component of 
our compensation for independent directors. Only independent directors are eligible to participate and to receive

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

deferred share units (“DSUs”) under the DSU Plan.  DSUs may be awarded by the Board from time to time to provide 
independent directors with appropriate equity-based compensation for the services they render to the Company 
and may be subject to terms and conditions with respect to vesting of such DSUs.  In addition, independent directors 
may elect to receive a portion or all of their respective annual cash remuneration in the form of DSUs, which will be 
fully vested upon such grant.  The number of DSUs to be awarded to a participant under the DSU Plan is determined 
by dividing the portion of that participant’s annual cash remuneration by the fair market value of a common share 
on the last day of the quarter in which such portion of the annual cash remuneration was earned. Pursuant to the 
DSU Plan, DSUs may only be settled by way of cash payment. A participant is not entitled to payment in respect of 
the DSUs until his or her death, retirement or removal from the Board.  The settlement amount of each DSU is based 
on the fair market value of a common share on the DSU redemption date multiplied by the number of DSUs being 
redeemed.  

Subsequent to December 31, 2019, 23,674 DSUs were issued to independent directors.   

(d)  Warrants 

As  at  December  31,  2019,  2,866,662  (December  31,  2018  –  3,333,328)  common  share  purchase  warrants  were 
outstanding with a weighted average exercise price of $1.20 and a weighted average remaining contractual life of 
1.95 years.     

During the year ended December 31, 2019, 466,666 warrants were exercised for gross proceeds of $0.6 million.

Under the terms of the Company’s contract with its primary customer, sales are provisionally priced on the date of 
sale  based  on  the  previous  month’s  average  copper  price.   The  final  sales  price  for  all  shipments  in  a  month  is 
determined at the end of the month in which the sale is recognized.  As at December 31, 2019, there are no sales 
subject to provisional pricing.  During the year ended December 31, 2019, the Company recognized $0.2 million 
(2018 - $1.7 million) related to provisional price adjustments related to such provisionally priced sales.

18. Recovery of Value Added Taxes

During  the  year  ended  December  31,  2019,  the  Company  recognized  a  recovery  of  $21.6  million  in  net  income 
related to value added taxes previously paid on sales in Brazil.  The recovery was recognized as a result of a Brazil 
Supreme Court ruling in 2017 that concluded that the relevant taxing authorities had historically used an incorrect 
methodology to determine such taxes.  The ruling set a precedent for all companies in Brazil but was required to be 
confirmed for the Company’s specific claim, which approval was received in July 2019.  These credits can be used 
to offset the payment of a variety of other taxes, including income taxes and taxes on future sales.  Of the recovery 
recognized, $3.2 million has been applied to taxes during the 2019 year, $12.2 million has been included in other 
current assets based on the expected timing of their use, with the remaining $6.2 million recognized in other non-
current assets in the statement of financial position. 

19. Income Taxes

31, 2018 - $7.2 million) which may be carried forward for 20 years to offset future taxable income, which expire 
between 2036 and 2039. 

20. Related Party Transactions

Key  management  personnel  consist  of  the  Company’s  directors  and  officers  and  their  compensation  includes 
director retainer fees and management salaries paid to these individuals, as well as share-based compensation.  The 
aggregate value of compensation paid to key management personnel for the year ended December 31, 2019 was 
$7.5 million ($5.4 million for the year ended December 31, 2018).  In addition, 444,265 options and 171,754 Share 
Units were issued to key management personnel during the year ended December 31, 2019 (1,100,155 options and 
130,636  Share  Units  for  the  year  ended  December  31,  2018)  with  $4.1  million  recognized  in  share-based 
compensation expense for the year ended December 31, 2019 ($2.3 million for the year ended December 31, 2018).  

During the year ended  December 31, 2019, key management personnel exercised 286,666 options and 300,000 
warrants for cash proceeds to the Company of $0.6 million and $0.4 million, respectively (133,000 options for $0.2 
million  for  the  year  ended  December  31,  2018).    During  the  year  ended  December  31,  2018,  key  management 
personnel converted convertible debentures into 1,476,164 common shares and 369,040 common share purchase 
warrants.  The warrants were subsequently exercised into 369,040 common shares. 

As at December 31, 2019, $3.9 million was payable to key management as incentive compensation and is included 
in  accounts  payable  and  accrued  liabilities  in  the  consolidated  financial  statements  (December  31,  2018  -  $2.7 
million).  Such amounts are unsecured, non-interest bearing and will be paid under normal trade terms. 

21. Financial Instruments

Fair value 

Fair values of financial assets and liabilities are determined based on available market information and valuation 
methodologies appropriate to each situation. However, some judgments are required in the interpretation of the 
market  data  to  produce  the  most  appropriate  realization  value  estimate.  As  a  consequence,  the  estimates 
presented herein do not necessarily indicate the amounts that could be realized in the current exchange market. 
The use of different market information and/or evaluation methodologies may have a material effect on the market 
value amount.

(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

As  at  December  31,  2019,  derivatives  were  measured  at  fair  value  based  on  Level  2  inputs.    The  fair  value  of 
derivatives is disclosed under market risk below. 

The  carrying  values  of  cash  and  cash  equivalents,  restricted  cash,  accounts  receivable,  deposits,  financial 
investments and accounts payable and accrued liabilities approximate their fair values due to their short terms to 
maturity or market rates of interest used to discount amounts.  The carrying value of value added, payroll and other 
taxes approximate fair value based on the discount rate applied.  At December 31, 2019, the carrying value of loans 
and borrowings is $159.4 million while the fair value is approximately $161.4 million.  The effective interest rates 
used to amortize these loans are a close approximation of market rates of interest at December 31, 2019 (Level 2 
of the fair value hierarchy).  

Credit risk 

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to 
meet its contractual obligations and arises principally from the Company’s receivables from customers. The carrying 
amount of the financial assets below represents the maximum credit risk exposure as at December 31, 2019 and 
December 31, 2018: 

Cash and cash equivalents
Restricted cash
Accounts receivable
Deposits

The  Company  invests  cash  and  cash  equivalents  as  well  as  restricted  cash  with  financial  institutions  that  are 
financially  sound  based  on  their  credit  rating.    The  Company’s  exposure  to  credit  risk  associated  with  accounts 
receivable is influenced mainly by the individual characteristics of each customer.  The Company currently has only 
three significant customers, all of which have no history of credit default with the Company.  The Company has not 
incurred credit losses during the years ended December 31, 2019 and 2018, nor has a provision for credit losses 
been recognized.     

Liquidity risk 

Liquidity  risk  is  the  risk  associated  with  the  difficulties  that  the  Company  may  have  meeting  the  obligations 
associated  with  financial  liabilities  that  are  settled  with  cash  payments  or  with  another  financial  asset.  The 
Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to meet 
their  maturity  obligations  on  the  expiration  dates,  under  normal  and  stressful  conditions,  without  causing 
unacceptable losses or with risk of undermining the normal operation of the Company.

Market risk  

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange 
rates,  and  commodity  prices.    The  purpose  of  market  risk  management  is  to  manage  and  control  exposures  to 
market risks, within acceptable parameters, while optimizing return. 

The Company may use derivatives, including forward contracts and swap contracts, to manage market risks.   

(i) Foreign exchange currency risk  

The Company’s subsidiaries in Brazil are exposed to exchange risks related to the US dollars and Euros.  In order to 
minimize  currency  mismatches,  the  Company  monitors  its  cash  flow  projections  considering  future  sales 
expectations indexed to US dollar variation in relation to the cash requirement to settle the existing financings. 

The Company's exposure to foreign exchange currency risk at December 31, 2019 relates primarily to $9.6 million 
(December  31,  2018  –  $10.2  million)  in  loans  and  borrowings  of  MCSA  denominated  in  US  dollars  and  Euros. 
Strengthening  (weakening)  in  the  Brazilian  Real  against  the  US  dollar  by  10%  and  20%,  would  have  increased 
(decreased) pre-tax net income by $0.6 million and $1.1 million, respectively (2018 – $0.7 million and $1.3 million). 
Strengthening (weakening) in the Brazilian Real against the Euro by 10% and 20%, would have increased (decreased) 
pre-tax net income by $0.4 million and $0.8 million, respectively (2018 – $0.4 million and $0.7 million). This analysis 
is based on the foreign currency exchange variation rate that the Company considered to be reasonably possible at 
the end of the year. The analysis assumes that all other variables, especially interest rates, are held constant. 

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage market risks.  
At December 31, 2019, the Company’s subsidiaries have entered into foreign exchange collar contracts at zero cost 
for notional amounts of $336.6 million with an average floor rate of 3.86 BRL to US Dollar and an average cap rate 
of  4.41  BRL  to  US  Dollar  (December  31,  2018  –  notional  amount  of  $21.5  million  in  foreign  exchange  forward 
contracts).  The maturity dates of these contracts are from January 15, 2020 to July 28, 2021 and are financially 
settled on a net basis.  The fair value of these contracts at December 31, 2019 was nil, (December 31, 2018 – an 
asset of $0.3 million, which was included in Derivatives in the statement of financial position.)  The change in fair 
value of foreign exchange collar contracts was a loss of $0.3 million for the year ended December 31, 2019 (a gain 
of  $1.1  million  for  the  year  ended  December  31,  2018)  and  has  been  recognized  in  foreign  exchange  loss.    In 
addition, in the year ended December 31, 2019, the Company recognized a realized gain of $0.2 million, (a loss of 
$10.1  million  for  the  year  ended  December  31,  2018)  related  to  the  settlement  of  foreign  currency  forward 
contracts. 

(ii) Interest rate risk  

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates of 
interest.   Management reduces interest rate risk exposure by entering into loans and borrowings with fixed rates 
of interest or by entering into derivative instruments that fix the ultimate interest rate paid. 

The Company is principally exposed to interest rate risk through its Term Facilities of $136.0 million and Brazilian 
Real denominated bank loans of $9.8 million.  Based on the Company’s net exposure at December 31, 2019, a 1% 
change  in  the  variable  rates  would  have  an  impact  of  $1.5  million  on  pre-tax  annual  net  income,  without 
consideration of the effects of the swap contracts below. 

In order to mitigate the above volatility due to variable rates on loans, as at December 31, 2019, the Company has 
entered into an interest rate swap contract to manage interest rate risk (see note 9(a)) associated with its Canadian 
Facilities.  The floating interest on a notional amount of $65 million was swapped for a fixed interest rate of 2.69%.  
The fair value of this contract at December 31, 2019 was a liability of $1.7 million and was included in Derivatives 
in the statement of financial position while the change in the fair value of this contract of $1.7 million was included 
in Finance Expenses in the statement of operations and comprehensive income.

(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

In addition, as at December 31, 2019, MCSA has entered into an interest rate and currency swap contract on the 
Plural Loan (see note 9(d)).  The floating interest on a notional amount of BRL$12 million was swapped for a fixed 
interest rate of 9.9% and the BRL currency on the loan was swapped for USD at a rate of 3.9500.  The fair value of 
this contract at December 31, 2019 was a liability of $0.1 million and was included in Derivatives in the statement 
of  financial  position  while  the  change  in  the  fair  value  of  this  contract  of  $0.1  million  was  included  in  Finance 
Expenses in the statement of operations and comprehensive income. 

(iii) Price risk

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity 
price  risks.    During  the  year  ended  December  31,  2019,  the  Company  had  entered  into  commodity  swap  collar 
contracts.  As at December 31, 2019, these commodity swap collar contracts have all matured and the balance was 
$nil.  The Company recognized a realized loss of $1.4 million for the year ended December 31, 2019 related to the 
settlement of commodity forward contracts.   

22. Capital Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going 
concern in order to pursue the development and production of its mine properties and to maintain a flexible capital 
structure for its projects for the benefit of its stakeholders. 

In the management of capital, the Company includes the components of shareholders’ equity and debt facilities. 

The  Company  manages  the  capital  structure  and  makes  adjustments  to  it  considering  changes  in  the  economic 
conditions and the risk characteristics of the underlying assets.  To maintain or adjust the capital structure, the 
Company may attempt to issue new loans and borrowings, common shares, or acquire or dispose of assets. 
Management reviews the capital structure on a regular basis to ensure that the above-noted objectives are met. 

Certain loan agreements contain operating and financial covenants that could restrict the ability of the Company 
and  its  subsidiary,  MCSA,  to,  among  other  things,  incur  additional  indebtedness  needed  to  fund  its  respective 
operations, pay dividends or make other distributions, make investments, create liens, sell or transfer assets or 
enter into transactions with affiliates.  There are no other restrictions or externally imposed capital requirements 
of the Company.

23. Segment Disclosure

The Company’s operations are segmented by entity between MCSA, NX Gold and corporate head office, which is 
consistent with internal reporting purposes.  The Company monitors the operating results of its operating segments 
separately  for  the  purpose  of  making  decisions  about  resource  allocation  and  performance  assessment.    The 
accounting policies used in the operating segments are the same as those contained in Note 3. 

Total revenue from MCSA is from two customers while total revenue from NX Gold is from one customer.

Cautionary Note Regarding Forward-Looking Statements

This Annual Report contains “forward-looking information” within the meaning of applicable Canadian securities laws. 
Forward-looking information includes statements that use forward-looking terminology such as “may”, “could”, “would”, 
“will”, “should”, “intend”, “target”, “plan”, “expect”, “budget”, “estimate”, “forecast”, “schedule”, “anticipate”, “believe”, 
“continue”, “potential”, “view” or the negative or grammatical variation thereof or other variations thereof or comparable 
terminology. Such forward-looking information includes, without limitation, statements with respect to the Company's 
expected operations at the Vermelhos and Pilar Mines as well as at the NX Gold Property, drilling plans, plans for the 
Company's exploration program, timing of any updated mineral resource and reserve updates and technical reports, the 
Company's ability to service its ongoing obligations, the Company's future production outlook, cash costs, capital 
resources, expenditures, the impact of new accounting standards and amendments on the Company's financial 
statements, and current global macroeconomic uncertainty stemming from the onset of Covid-19.
Forward-looking information is not a guarantee of future performance and is based upon a number of estimates and 
assumptions of management in light of management’s experience and perception of trends, current conditions and 
expected developments, as well as other factors that management believes to be relevant and reasonable in the 
circumstances, as of the date of this Press Release including, without limitation, assumptions about: favourable equity and 
debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production, 
development and exploration of the Company’s properties and assets; future prices of copper and other metal prices; the 
timing and results of exploration and drilling programs; the accuracy of any mineral reserve and mineral resource 
estimates; the geology of the Vale do Curaçá Property, NX Gold Property and the Boa Esperanҫa Property being as 
described in the technical reports for these properties; production costs; the accuracy of budgeted exploration and 
development costs and expenditures; the price of other commodities such as fuel; future currency exchange rates and 
interest rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and 
effective manner; political and regulatory stability; the receipt of governmental, regulatory and third party approvals, 
licenses and permits on favourable terms; obtaining required renewals for existing approvals, licenses and permits on 
favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and capital goods 
markets; availability of equipment; positive relations with local groups and the Company’s ability to meet its obligations 
under its agreements with such groups; and satisfying the terms and conditions of the Company’s current loan 
arrangements. While the Company considers these assumptions to be reasonable, the assumptions are inherently subject 
to significant business, social, economic, political, regulatory, competitive, global health, and other risks and uncertainties,
contingencies and other factors that could cause actual actions, events, conditions, results, performance or achievements 
to be materially different from those projected in the forward-looking information. Many assumptions are based on 
factors and events that are not within the control of the Company and there is no assurance they will prove to be correct.

Furthermore, such forward-looking information involves a variety of known and unknown risks, uncertainties and other 
factors which may cause the actual plans, intentions, activities, results, performance or achievements of the Company to 
be materially different from any future plans, intentions, activities, results, performance or achievements expressed or 
implied by such forward-looking information. Such risks include, without limitation the risk factors listed under the heading 
“Risk Factors” in the Annual Information Form for the year ended December 31, 2019 and dated March 12, 2020.

Although the Company has attempted to identify important factors that could cause actual actions, events, conditions, 
results, performance or achievements to differ materially from those described in forward-looking information, there may 
be other factors that cause actions, events, conditions, results, performance or achievements to differ from those 
anticipated, estimated or intended.

The Company cautions that the foregoing lists of important assumptions and factors are not exhaustive. Other events or 
circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or 
implied by, the forward-looking information contained herein. There can be no assurance that forward-looking information 
will prove to be accurate, as actual results and future events could differ materially from those anticipated in such 
information. Accordingly, readers should not place undue reliance on forward-looking information.

Forward-looking information contained herein is made as of the date of this Annual Report and the Company disclaims any 
obligation to update or revise any forward-looking information, whether as a result of new information, future events or 
results or otherwise, except as and to the extent required by applicable securities laws.
