CHAIRMAN’S LETTER

2021  marked  a  year  of  record 
operating and financial performance 
as  well  as  the  achievement  of 
several strategic initiatives that have 
positioned  Ero  Copper  to  pursue 
a  peer-leading  growth trajectory  in 
the years ahead. 

Beginning  with  the  completion  of  an  optimized  feasibility 
study  on  the  Boa  Esperança  Project,  our  team  laid  the 
foundation for  high-return  organic  growth  aimed  at  more 
than  doubling  copper  production  over  the  next  four years 
while maintaining first quartile operating costs. Importantly, 
the  timing  of  this  projected  growth  aligns  with  significant 
anticipated  copper  demand  growth  related  to  the 
advancement of urgent global decarbonization initiatives.

As a supplier of an element integral to the “Environmental 
Revolution”,  and  specifically  the  achievement  of  carbon 
neutrality,  we  are  proud  to  produce  some  of  the  world’s 
lowest carbon-intensive copper due to our access to power 
sourced  primarily  from  renewable  energy.  In  2021,  we 
continued  to  deepen  our  commitment  to  sustainability  by 
forming  an  internal  Management  Committee  on  Climate 
Change whose  mandate  is to  incorporate  climate  change 
risks  and  opportunities 
into  the  Company’s  strategy, 
business plans and disclosures. In support of this mandate, 
we became a signatory of the U.N. Global Compact and a 
supporter  of  the  Task  Force  on  Climate-Related  Financial 
Disclosures  (TCFD)  and  progressed  efforts  to  define 
sustainability targets across our operations.

As  we  prepare  to  commence  construction  of  our 
Boa  Esperança  Project,  the  foundation  of  our  Company 
has  never  been  stronger.  We  have  defined  compelling 
growth projects at both the MCSA Mining Complex and the 
NX  Gold  Mine,  in  addition  to  the  planned  development  of 
Boa  Esperança,  and  have  worked  to  secure  and  support 
this  growth  by  bolstering  our  balance  sheet  subsequent 
to  year-end  with  the  issuance  of  $400  million  in  senior 
unsecured notes due 2030.

I  am  extremely  proud  of  Ero  Copper’s  accomplishments 
in  2021  and would  like to thank  all  of  our  stakeholders for 
their  continued  efforts  and  unwavering  support.  Despite 
our very strong performance in 2021, I truly believe the best 
is still ahead.

LETTER FROM THE CEO

Ero  Copper  delivered  another year  of  exceptional  performance  in  2021  and 
made  significant  progress  in  defining  a  strategy  to  pursue  transformational 
organic growth in the years ahead. We also made strong progress in shaping 
our sustainability strategy to further differentiate our Company as one of the 
world’s lowest carbon-intensive copper producers. 

Record 2021 Operating and Financial Performance

High-Return Organic Growth Strategy

The  MCSA  Mining  Complex  delivered  another  consecutive 
year  of  record  copper  production  at  first  quartile  C1  cash 
costs.  This  performance  was  particularly  noteworthy  due 
to  the  impact  of  downtime  associated  with  scheduled 
maintenance  and  upgrades  performed  at  the  Caraíba 
Mill  in  the  second  and  third  quarters  to  prepare  the  mill 
for  expanded  operations  and  higher  throughput  volumes 
related  to  the  ramp  up  of  mining  activity  at  the  Surubim 
Mine  as well  as future  growth  plans  at the  Pilar  Mine  and 
Deepening Extension Zone.

During the year, we defined a strategy, which we announced 
in early 2022, to more than double our copper production and 
become a 100,000 tonne per year copper and 60,000 ounce 
per  year  gold  producer  by  2025  while  maintaining  first 
quartile  operating  costs  and  industry-leading  returns  on 
invested  capital  (“ROIC”).  This  growth  strategy  represents 
the  culmination  of  aggressive  exploration  drilling  over  the 
past  several  years  as  well  as  thoughtful  project  and  mine 
planning  to  identify  opportunities  for  value  creation  within 
our existing portfolio.

Operating  performance  from  the  NX  Gold  Mine  was  also 
strong,  with  production  exceeding  the  high-end  of  full-
year gold production guidance. Construction of a modular 
paste-fill  plant  was  completed  in  the  third  quarter,  and 
commissioning  concluded  shortly  after year-end. The  new 
paste-fill plant is expected to improve overhand cut and fill 
mining operations and enhance pillar recovery throughout 
the mine.

As  a  result  of  our  strong  operating  performance  during 
the  year,  we  reported  a  number  of  record  financial  results 
that contributed to an increase of $156 million to year-end 
available  liquidity  of  $230  million,  including  $130  million 
in  cash  and  cash  equivalents  and  $100  million  in  undrawn 
availability under our senior secured revolving credit facility.

The  results  of  these  efforts  included  the  announcement 
of  an  optimized  Feasibility  Study  on  the  Boa  Esperança 
Project,  outlining  a  project  with  a  41.8%  after-tax  internal 
rate of return(1), a $380 million after-tax net present value 
(8% discount rate)(1), and average annual copper production 
of  approximately  35,000  tonnes  at  an  average  C1  cash 
cost  of  $1.12(1)  per  pound  of  copper  produced  in  the  first 
five  years  of  production.  In  February  2022,  our  Board  of 
Directors approved the construction of the Boa Esperança 
Mine, which is expected to commence in the second quarter 
of  2022  with  commercial  production  anticipated  in  the 
second half of 2024. During its first full year of production 
in  2025,  the  Boa  Esperança  Mine  is  expected  to  produce 
approximately 50,000 tonnes of copper, doubling our total 
copper production to nearly 100,000 tonnes by 2025.

“As we endeavor to double our annual copper production over the next 
four years, we are working to establish reduction targets for greenhouse 
gas emissions that we believe further improve our position as one of the 
world’s cleanest copper producers.”

David Strang - Chief Executive Officer

Throughout 2021, we released exceptional drill results from 
the Deepening Extension Zone, including the best intercept 
by our Company in the Curaçá Valley to date. The success 
of our exploration efforts within this zone has continued to 
exceed our expectations with respect to the size and quality 
of  mineralization  and  resulted  in  a  56%  increase  to  the 
Deepening Extension Zone’s proven and probable mineral 
reserves in 2021 compared to 2020. This growth in mineral 
reserves, combined with the potential for further extensions 
at  depth,  as  well  as  exploration  success  in  the  shallower 
areas  of  the  Pilar  Mine,  drove  an  initiative  to  optimize 
the  development  strategy  for  the  Deepening  Extension 
Zone’s new external shaft to allow for higher sustained ore 
production levels from the Pilar Mine.

Following  months  of  engineering  design  work,  our  team 
finalized plans to create a two-mine system at the Pilar Mine, 
known  as  “Pilar  3.0”, which was  announced  in  early  2022 
and  is  expected  to  enable  higher  annual  ore  production 
volumes  of  2.6  to  3.0  million  tonnes  from  the  Pilar  Mine, 
including the Deepening Extension Zone, compared to the 
current production rate of approximately 1.3 million tonnes 
per annum.

At  the  NX  Gold  Mine,  we  announced  another  growth 
initiative shortly after year-end known as “NX 60” based on 
strong drill results from the mine throughout 2021, including 
the best intercept in the history of the mine as well as the 
discovery  of  a  new  high-grade  extension  of  the  Matinha 
Vein.  The  NX  60  initiative  is  focused  on  sustaining  longer 
term gold production of approximately 60,000 ounces per 
year, including expected production from the Matinha Vein 
beginning in 2024.

Deep Commitment to ESG

Ero  Copper  is  deeply  committed  to  strong  environmental, 
social  and  governance  principles.  This  extends  from  our 
health  and  safety  initiatives  and  performance  to  our 
governance policies and sustainability strategy.

We  are  fortunate  to  operate  in  Brazil,  which  allows  us  to 
produce some of the lowest carbon-intensive copper in the 
world. Brazil is a global leader in the use of renewable energy 
with  85%  of  its  power  generated  from  renewable  sources, 
including 66% from hydropower. We believe this affords our 
Company, and the copper concentrate we produce, a growing 
competitive  advantage  as  copper  is  a  key  input  required 
to  advance  global  decarbonization  initiatives.  As  a  result, 
end-users of refined copper globally are increasingly focused 
on greenhouse gas emissions throughout the supply chain.

As  we  endeavor  to  double  our  annual  copper  production 
over  the  next  four  years,  we  are  working  to  establish 
reduction  targets  for  greenhouse  gas  emissions  that  we 
believe will further improve our position as one of the world’s 
cleanest copper producers.

Outlook for 2022

As  we  entered  2022,  we  continued  to  position  our 
Company for transformational growth with the issuance of 
$400 million in senior unsecured notes due 2030, providing 
ample  balance  sheet  liquidity  to  fund  construction  of  the 
Boa  Esperança  Project  as  well  as  other  strategic  growth 
projects. We  are well-prepared  and  excited to  execute  on 
the compelling strategy we have defined over the last year 
while  remaining true to  our  core  principles  around  health, 
safety and sustainability.

•

•

In	February	2022,	the	Company	closed	an	offering	of	$400	million	of	senior	unsecured	notes	due	2030.	
The	Company	subsequently	used	approximately	$50	million	of	net	proceeds	from	the	offering	to	repay	
the	outstanding	balance	under	its	senior	secured	revolving	credit	facility.	The	Company	intends	to	use	
the	 remaining	 proceeds,	 together	 with	 cash	 on	 hand,	 to	 fund	 capital	 expenditures	 related	 to	 the	
construction	of	the	Boa	Esperança	Project	and	for	general	corporate	purposes.
Concurrent	with	the	closing	of	the	$400	million	senior	unsecured	notes	offering,	the	Company	reduced	
the	size	of	its	senior	secured	revolving	credit	facility	from	$150	million	to	$75	million.
The	 Company's	 pro	 forma	 year-end	 liquidity	 position	 was	 approximately	 $550	 million,	 including	
approximately	$475	million	in	cash	and	cash	equivalents	and	$75	million	of	undrawn	availability	under	
the	Company's	senior	revolving	credit	facility.

Boa	Esperança	Project,	which	is	expected	to	commence	construction	in	Q2	2022.

Q4	2021	Highlights

Strong	Q4	2021	operating	performance,	including	growing	contributions	from	the	Surubim	open	pit	mine	at	
the	MCSA	Mining	Complex,	drove	solid	quarterly	financial	results

•

The	 MCSA	 Mining	 Complex	 processed	 646,319	 tonnes	 of	 ore	 grading	 2.01%	 copper,	 producing	 11,918	
tonnes	of	copper	in	concentrate	during	the	quarter	after	metallurgical	recoveries	of	92.7%.

•

• Higher	quarter-on-quarter	copper	production	was	driven	primarily	by	increased	mill	throughput	volumes	
related	to	(i)	the	ramp-up	of	mining	activity	and	processing	of	stockpiled	ore	from	the	Surubim	open	pit	
mine	 and	 (ii)	 a	 return	 to	 higher	 mill	 capacity	 levels	 following	 the	 completion	 of	 scheduled	 mill	
maintenance,	which	impacted	mill	throughput	volumes	in	Q2	and	Q3	of	2021.
The	NX	Gold	Mine	processed	47,159	tonnes	grading	6.24	grams	per	tonne,	producing	8,544	ounces	of	
gold	after	metallurgical	recoveries	of	90.3%	and	5,859	ounces	of	silver	produced	as	by-product.	
Commissioning	 of	 the	 NX	 Gold	 Mine's	 paste-fill	 plant,	 where	 construction	 was	 completed	 in	 Q3	 2021,	
continued	 during	 the	 fourth	 quarter	 and	 handover	 to	 operations	 was	 completed	 in	 January	 2022.	 The	
paste-fill	 plant	 is	 expected	 to	 improve	 overhand	 cut	 and	 fill	 mining	 operations	 and	 enhance	 pillar	
recovery	throughout	the	mine.
C1	 cash	 costs	 during	 the	 quarter	 were	 $0.96	 per	 pound	 of	 copper	 produced	 at	 the	 MCSA	 Mining	
Complex	(see	Non-IFRS	Measures).

•

•

• At	the	NX	Gold	Mine,	C1	cash	costs	and	AISC	during	the	quarter	were	$582	and	$910,	respectively,	per	

•

ounce	of	gold	produced	(see	Non-IFRS	Measures).
Strong	cash	flows	from	operations	during	the	quarter	of	$66.7	million	contributed	to	increased	available	
liquidity	at	year-end	of	$230.1	million,	including	cash	and	cash	equivalents	of	$130.1	million	and	$100.0	
million	of	undrawn	availability	under	the	Company's	senior	revolving	credit	facility.

2021	updated	mineral	reserves	and	resources	for	the	MCSA	Mining	Complex	and	the	NX	Gold	Mine	continue	to	
highlight	the	Company's	track-record	of	generating	shareholder	value	through	exploration

•

Exceptional	drill	results	from	the	Deepening	Extension	Zone	throughout	2021	resulted	in	a	56%	increase	
in	proven	and	probable	mineral	reserves	within	the	zone	and	contributed	to	an	increase	of	13%	in	total	
proven	and	probable	mineral	reserves	for	the	MCSA	Mining	Complex.

• A	 32%	 increase	 in	 measured	 and	 indicated	 mineral	 resources	 (25%	 increase	 in	 proven	 and	 probable	
reserves)	for	the	NX	Gold	Mine	was	driven	by	exploration	of	high-grade	extensions	of	the	Santo	Antonio	
Vein	and	the	discovery	of	a	new	high-grade	extension	of	the	Matinha	Vein.

Organic	Growth	Projects

• During	 the	 quarter,	 the	 Company	 finalized	 a	 redesign	 of	 the	 new	 external	 shaft	 at	 the	 Deepening	
Extension	Zone	to	allow	for	higher	sustained	ore	production	rates	from	the	Pilar	Mine	as	part	of	the	Pilar	
3.0	 initiative,	 announced	 subsequent	 to	 year-end.	 Plans	 to	 construct	 a	 larger	 shaft	 were	 driven	 by	
continued	exploration	success	within	the	Deepening	Extension	Zone	as	well	as	within	shallower	areas	of	
the	Pilar	Mine,	enabling	the	creation	of	a	two-mine	system	whereby	the	upper	levels	of	the	mine	will	be	
serviced	by	the	existing	shaft,	while	the	Deepening	Extension	Zone	will	utilize	the	new,	larger	external	
shaft.	 Pilar	 3.0	 is	 expected	 to	 enable	 higher	 annual	 production	 volumes	 of	 2.6	 to	 3.0	 million	 tonnes	
compared	 to	 the	 current	 production	 rate	 of	 approximately	 1.3	 million	 tonnes	 per	 annum	 at	 the	 Pilar	
Mine.

• As	previously	noted,	the	Company	announced	that	its	Board	of	Directors	approved	the	construction	of	
the	Boa	Esperança	Project	subsequent	to	year-end.	Construction	is	expected	to	commence	in	Q2	2022,	
with	 first	 production	 anticipated	 in	 H2	 2024.	 In	 preparation	 for	 construction	 of	 Boa	 Esperança,	 the	
Company	has	made	significant	progress	on	key	workstreams,	including:	

◦

Advancing	 critical-path	 contracts	
construction	with	equipment	mobilization	expected	in	Q2	2022;
Detailed	engineering	and	construction	designs;	and,

including	 early	 works,	 power	

◦
◦ Ongoing	drill	program	efforts,	including	further	exploration	of	the	Gap	Zone	and	completion	of

The	Company’s	MCSA	Mining	Complex	delivered	another	strong	operating	quarter	in	Q4	2021,	producing	11,918	
tonnes	 of	 copper	 resulting	 in	 full	 year	 2021	 copper	 production	 of	 45,511	 tonnes.	 With	 the	 completion	 of	 the	
second	and	final	phase	of	scheduled	mill	maintenance	at	the	MCSA	Mining	Complex	during	Q3	2021,	there	was	a	
meaningful	increase	in	tonnes	processed	quarter-on-quarter.

During	Q4	 2021,	at	 the	 Pilar	 Mine,	293,627	 tonnes	of	ore	were	mined	grading	1.97%	copper	(as	compared	to	
346,040	tonnes	of	ore	grading	2.03%	copper	during	Q3	2021).	At	the	Vermelhos	Mine,	226,054	tonnes	of	ore	
were	 mined	 grading	 2.94%	 copper	 (as	 compared	 to	 231,543	 tonnes	 of	 ore	 grading	 1.49%	 copper	 during	 Q3	
2021).	At	the	Surubim	Mine,	129,885	tonnes	of	ore	were	mined	grading	0.72%	copper.	Contributions	from	the	
three	mines	resulted	in	total	ore	mined	during	the	period	of	649,566	tonnes	grading	2.01%	copper.	During	Q4	
2021,	 646,319	 tonnes	 of	 ore	 grading	 2.01%	 copper	 were	 processed,	 producing	 11,918	 tonnes	 of	 copper	 after	
average	metallurgical	recoveries	of	92.7%.	

Total	full	year	2021	processed	volumes	of	2,370,571	tonnes	grading	2.08%	copper	generated	copper	production	
of	45,511	tonnes	in	concentrate	after	average	metallurgical	recoveries	of	92.4%.

Initial	 production	 from	 the	 Surubim	 open	 pit	 occurred	 in	 Q4	 2021,	 including	 the	 processing	 of	 ore	 stockpiled	
during	 pre-stripping.	 The	 Surubim	 Mine	 is	 expected	 to	 contribute	 to	 higher	 throughput	 volumes	 and	 lower	
average	processed	copper	grades	at	the	MCSA	Mining	Complex	in	2022.

C1	cash	costs	per	pound	of	copper	produced	during	Q4	2021	averaged	$0.96	(see	Non-IFRS	Measures),	resulting	
in	full	year	2021	C1	cash	costs	per	pound	of	copper	produced	of	$0.77.	Full-year	cost	performance	was	at	the	
low	 end	 of	 cost	 guidance	 due	 to	 elevated	 grades	 mined	 and	 processed	 relative	 to	 budget,	 strong	 overall	
operational	performance	at	the	MCSA	Mining	Complex,	and	continued	weakness	of	the	BRL	versus	the	US	dollar.

The	Company’s	exploration	programs	at	the	MCSA	Mining	Complex	are	focused	on	four	primary	objectives	for	
2022:	(i)	infill	and	extension	drilling	in	the	upper	levels	(above	level	-965)	of	the	Pilar	Mine,	(ii)	focused	infill	and	
exploration	 drilling	 at	 the	 Vermelhos	 Mine	 aimed	 on	 extending	 the	 known	 limits	 of	 high-grade	 mineralization	
with	the	goal	of	supplementing	the	grade	profile	of	the	mine	over	the	near-	to	medium-term,	(iii)	re-evaluation	
of	past	producing	open	pit	mines	including	extension	drilling	at	depth	at	Lagoa	da	Mina	and	Surubim,	and	(iv)	
regional	 exploration	 of	 the	 broader	 MCSA	 Mining	 Complex	 land	 package	 focused	 on	 making	 new	 regional	
discoveries.

(1)		 NX	Gold	metallurgical	recoveries	during	H1	2021	included	gold	recovered	through	the	Company’s	“Zero	Loss”	campaign,	including	
reprocessed	mill	and	foundry	scrap,	and	therefore	may	not	be	representative	of	metallurgical	recoveries	from	mined	ore	during	the	
period.

(2)	 Realized	 Au	 price	 includes	 the	 effect	 of	 ounces	 sold	 under	 the	 stream	 arrangement	 with	 Royal	 Gold.	 See	 "Realized	 Gold	 Price"	

section	of	"Non-IFRS	Measures"	for	detail.

At	the	NX	Gold	Mine,	gold	production	decreased	9%,	as	expected,	compared	to	Q3	2021	due	to	lower	planned	
head	grades	from	Santo	Antonio.	Production	during	Q4	2021	totaled	8,544	ounces	of	gold	and	5,859	ounces	of	
silver	(as	by-product)	from	total	mill	feed	of	47,159	tonnes	grading	6.24	grams	per	tonne	gold	after	metallurgical	
recoveries	 of	 90.3%	 during	 the	 period.	 Metallurgical	 recoveries	 rates	 were	 lower	 in	 Q4	 2021	 primarily	 due	 to	
lower	head	head	grades	during	the	period.

During	2021,	the	NX	Gold	Mine	delivered	production	of	37,798	ounces	of	gold	and	25,031	ounces	of	silver	from	
total	 mill	 feed	 of	 171,581	 tonnes	 grading	 7.27	 grams	 per	 tonne	 gold	 after	 metallurgical	 recoveries	 of	 94.2%.	
Metallurgical	 recovery	 rates	 were	 elevated	 in	 H1	 2021	 due	 to	 gold	 contributions	 from	 mill	 and	 foundry	 scrap	
recycling	efforts.	

The	NX	Gold	Mine	achieved	C1	cash	costs	and	AISC	during	Q4	2021	of	$582	and	$910,	respectively,	per	ounce	of	
gold	produced,	bringing	2021	C1	cash	costs	and	AISC	to	$525	and	$732,	respectively,	per	ounce	of	gold	produced	
(see	Non-IFRS	Measures).

Commissioning	of	the	NX	Gold	Mine's	paste-fill	plant,	where	construction	was	completed	in	Q3	2021,	continued	
during	the	fourth	quarter	and	handover	to	operations	concluded	in	January	2022.	The	paste-fill	plant	is	expected	
to	improve	overhand	cut	and	fill	mining	operations	and	enhance	pillar	recovery	throughout	the	mine.

Exploration	activities	at	the	NX	Gold	Mine	continue	to	focus	on	three	primary	objectives	for	2022:	(i)	infill	and	
extension	of	the	Santo	Antonio	Vein,	(ii)	delineation	and	discovery	of	new	gold-bearing	veins	within	the	NX	Gold	
Mine	system	near	existing	infrastructure,	such	as	the	Matinha	Vein,	and	(iii)	regional	exploration	on	the	broader	
NX	Gold	land	package.

NX	Gold	Transaction

In	 August	 2021,	 the	 Company	 completed	 the	 closing	 of	 a	 streaming	 agreement	 with	 Royal	 Gold	 in	 relation	 to	
gold	production	from	the	NX	Gold	mine.	The	Company	received	upfront	cash	consideration	of	$100.0	million	for	
the	purchase	of	25%	of	an	equivalent	amount	of	gold	to	be	produced	from	the	NX	Gold	mine	until	93,000	ounces	
of	gold	have	been	delivered	and	thereafter	decreasing	to	10%	of	gold	produced	over	the	remaining	life	of	the	
mine.	Royal	Gold	will	make	ongoing	payments	equal	to	20%	of	the	then	prevailing	spot	gold	price	for	each	ounce	
of	gold	delivered	until	49,000	ounces	of	gold	have	been	received	and	40%	of	the	prevailing	spot	gold	price	for	
each	ounce	of	gold	delivered	thereafter.	Additional	payment	obligations	of	Royal	Gold	include:

i. Up	to	US$5	million,	available	through	the	end	of	2024,	payable	based	upon	the	number	of	ounces	of	gold	
added	to	the	Measured	and	Indicated	mineral	resource	categories	as	compared	to	the	mineral	resources	
as	of	the	effective	date	of	the	NX	Gold	Transaction	at	a	rate	of	US$20	per	ounce;	

ii. Up	 to	 US$5	 million,	 available	 from	 2022	 through	 the	 end	 of	 2024,	 payable	 based	 upon	 completion	 of	
planned	meters	of	drilling	within	the	exploration	concessions	of	the	NX	Gold	mine	at	a	rate	of	US$100	per	
meter;	and,

iii. US$5	per	ounce	of	gold	delivered	under	the	NX	Gold	Transaction	payable	to	the	Company	as	contribution	
towards	ongoing	environmental,	social	and	governance	initiatives	within	the	area	of	influence	of	the	mine.

The	contract	will	be	settled	by	the	Company	delivering	gold	to	Royal	Gold.	The	$100.0	million	upfront	proceeds	
from	Royal	Gold	has	been	recognized	as	deferred	revenue	and	the	Company	recognizes	amounts	in	revenue	as	
gold	 is	 delivered.	 Each	 period,	 management	 estimates	 the	 cumulative	 amount	 of	 the	 deferred	 revenue	
obligation	that	has	been	satisfied	and,	therefore,	recognized	as	revenue.	Key	inputs	into	the	estimate	at	closing	
of	the	transaction	included	an	estimated	long-term	gold	price	of	$1,750	per	ounce	and	a	life	of	mine	production	
schedule	for	the	NX	Gold	mine	that	includes	mineral	reserves	and	a	portion	of	the	mineral	resources.

copper	as	compared	to	22.6	million	lbs	of	copper	in	Q4	2020.	The	increase	in	revenues	was	primarily	attributed	to	higher	realized

Revenues	from	gold	sales	in	Q4	2021	was	$14.9	million	(Q4	2020	-	$18.6	million),	which	included	the	sale	of	7,779	ounces	of	gold	at	a	
realized	 price	 of	 $1,784	 per	 ounce,	 compared	 to	 10,100	 ounces	 of	 gold	 at	 a	 realized	 price	 of	 $1,867	 per	 ounce	 for	 Q4	 2020.	 The	
decrease	in	revenues	was	primarily	attributable	to	lower	realized	prices	and	lower	sales	volume	than	in	the	comparative	quarter.

2.	 Cost	of	sales	for	Q4	2021	from	copper	sales	was	$43.6	million	(Q4	2020	-	$25.8	million)	which	primarily	comprised	of	$11.6	million	
(Q4	2020	-	$8.0	million)	in	depreciation	and	depletion,	$11.2	million	(Q4	2020	-	$6.2	million)	in	salaries	and	benefits,	$6.8	million	(Q4	
2020	-	$3.8	million)	in	materials	and	consumables,	$4.8	million	(Q4	2020	-	$3.1	million)	in	maintenance	costs,	$4.7	million	(Q4	2020	-	
$2.9	million)	in	contracted	services,	$2.3	million	(Q4	2020	-	$1.7	million)	in	utilities	and	$2.0	million	(Q4	2020	-	$1.4	million)	in	sales	
expenses.	The	increase	in	cost	of	sales	in	Q4	2021	as	compared	to	Q4	2020	was	primarily	attributable	to	a	34%	increase	in	tonnes	
processed,	as	well	as	increases	in	salaries	and	benefits	and	costs	in	materials	and	consumables.

Cost	of	sales	for	Q4	2021	from	gold	sales	was	$6.9	million	(Q4	2020	-	$5.5	million)	which	primarily	comprised	of	$2.0	million	(Q4	
2020	-	$1.2	million)	in	depreciation	and	depletion,	$1.3	million	(Q4	2020	-	$1.1	million)	in	contracted	services,	$1.6	million	(Q4	2020	-	
$1.4	million)	in	salaries	and	benefits,	$0.8	million	(Q4	2020	-	$0.9	million)	in	materials	and	consumables,	$0.5	million	(Q4	2020	-	$0.5	
million)	 in	 utilities,	 and	 $0.4	 million	 (Q4	 2020	 -	 $0.4	 million)	 in	 maintenance	 costs.	 The	 increase	 in	 cost	 of	 sales	 in	 Q4	 2021	 as	
compared	to	Q4	2020	is	primarily	attributable	to	increases	in	cost	of	contracted	services	and	salaries	and	benefits	at	NX	Gold.

3.	 General	and	administrative	expenses	for	Q4	2021	was	primarily	comprised	of	$4.9	million	(Q4	2020	-	$2.9	million)	in	salaries	and	
consulting	fees,	$3.0	million	(Q4	2020	-	$2.2	million)	in	office	and	administration	expenses,	$3.0	million	(Q4	2020	-	$2.5	million)	in	
incentive	 payments,	 and	 $0.7	 million	 (Q4	 2020	 -	 $0.2	 million)	 in	 travel-related	 costs.	 The	 increase	 in	 general	 and	 administrative	
expenses	was	attributed	to	an	increase	in	corporate	headcount	and	administrative	activities	to	support	overall	growth	in	operations,	
as	well	as	to	enhance	governance	and	compliance	with	the	Company's	recent	NYSE	listing.

Finance	 expense	 for	 Q4	 2021	 was	 $2.3	 million	 (Q4	 2020	 -	 $2.6	 million)	 and	 is	 primarily	 comprised	 of	 interest	 on	 loans	 at	 the	
corporate	 head	 office	 of	 $0.3	 million	 (Q4	 2020	 -	 $1.6	 million),	 accretion	 of	 deferred	 revenue	 of	 $0.9	 million	 (Q4	 2020	 -	 $nil),	
accretion	of	the	asset	retirement	obligations	of	$0.4	million	(Q4	2020	-	$0.2	million)	and	other	finance	expense	of	$0.2	million	(Q4	
2020	-	$1.0	million).	The	overall	decrease	in	finance	expense	in	Q4	2021	as	compared	to	Q4	2020	is	primarily	attributable	to	overall	
lower	debt	levels	partially	offset	by	an	increase	in	non-cash	accretion	expense	on	deferred	revenue.	

Foreign	exchange	loss	for	Q4	 2021	was	 $4.4	million	 (Q4	 2020	 -	 $27.1	 million	 gain).	This	amount	is	primarily	 comprised	of	foreign	
exchange	 gain	 on	 unrealized	 derivative	 contracts	 of	 $3.3	 million	 (Q4	 2020	 -	 $27.7	 million	 gain),	 foreign	 exchange	 loss	 on	 USD	
denominated	debt	of	$1.6	million	(Q4	2020	-	$7.7	million	gain)	in	MCSA	for	which	the	functional	currency	is	the	BRL,	partially	offset	
by	a	realized	foreign	exchange	loss	on	derivative	contracts	of	$6.2	million	(Q4	2020	-	$7.8	million	loss)	and	other	foreign	exchange	
gains	of	$0.1	million	(Q4	2020	-	$0.4	million	losses).	The	foreign	exchange	gains	were	primarily	a	result	of	a	weakening	of	BRL	against	
USD	in	Q4	2021	as	compared	to	the	prior	quarter.	The	foreign	exchange	gains	on	unrealized	derivative	contracts	are	a	result	of	mark-
to-market	calculations	at	period	end	and	may	not	represent	the	amount	that	will	ultimately	be	realized,	which	will	depend	on	future	
changes	to	the	USD/BRL	foreign	exchange	rates.

In	 Q4	 2020,	 the	 Company	 recognized	 a	 recovery	 of	 $8.9	 million	 in	 net	 income	 related	 to	 value	 added	 taxes.	 The	 recovery	 was	
recognized	as	a	result	of	a	study	conducted	to	revisit	certain	tax	positions	which	concluded	that	it	is	probable	that	additional	tax	
credits	are	available	to	be	used	to	offset	a	variety	of	taxes.	

In	Q4	2021,	the	Company	recognized	$4.5	million	in	income	tax	expense	(Q4	2020	-	$13.2	million	expense),	primarily	as	a	result	of	an	
increase	in	taxable	income	from	operations.

The	foreign	currency	translation	loss	is	a	result	of	a	weakening	of	the	BRL	against	the	USD	during	Q4	2021	when	translating	the	net

1.	 Revenues	from	copper	sales	in	2021	was	$424.0	million	(2020	-	$260.9	million),	which	included	the	sale	of	100,788,419	lbs	of	copper	
compared	 to	 94,387,312	 lbs	 of	 copper	 for	 Fiscal	 2020.	 The	 increase	 in	 revenues	 is	 primarily	 attributed	 to	 higher	 realized	 copper	
prices	and	increased	sales	volume	compared	to	the	prior	year.

Revenues	from	gold	sales	 in	2021	was	 $66.0	million	 (2020	 -	 $63.2	 million),	which	 included	the	sale	of	37,437	 ounces	of	gold	at	a	
realized	 price	 of	 $1,783	 per	 ounce,	 compared	 to	35,855	 ounces	 of	 gold	 sold	 at	 a	 realized	 price	 of	$1,795	 per	 ounce	 in	 2020.	 The	
increase	in	revenues	was	attributable	to	higher	sales	volume	compared	to	the	prior	year.

2.	 Cost	of	sales	for	2021	from	copper	sales	was	$142.9	million	(2020	-	$114.5	million)	which	consisted	of	$39.2	million	(2020	-	$35.7	
million)	 in	 depreciation	 and	 depletion,	 $33.2	 million	 (2020	 -	 $24.6	 million)	 in	 salaries	 and	 benefits,	 $22.8	 million	 (2020	 -	 $15.1	
million)	in	materials	and	consumables,	$16.4	million	(2020	-	$12.5	million)	in	maintenance	costs,	$15.5	million	(2020	-	$14.8	million)	
in	 contracted	 services,	 $8.5	 million	 (2020	 -	 $6.5	 million)	 in	 utilities	 and	 $6.7	 million	 (2020	 -	 $4.9	 million)	 in	 sales	 expenses.	 The	
increase	 in	 cost	 of	 sales	 was	 primarily	 attributed	 to	 a	 6%	 increase	 in	 copper	 tonnes	 sold,	 increases	 in	 salaries	 and	 benefits	 and	
increased	costs	in	materials	and	consumables	at	MCSA,	as	well	as	preventative	maintenance	conducted	to	help	prepare	the	MCSA	
Mining	Complex	mill	for	expanded	operations	and	higher	throughput.

Cost	of	sales	for	2021	from	gold	sales	was	$28.2	million	(2020-	$21.4	million)	which	primarily	comprised	of	$7.8	million	(2020	-	$3.5	
million)	in	depreciation	and	depletion,	$6.3	million	(2020	-	$5.5	million)	in	salaries	and	benefits,	$5.8	million	(2020	-	$3.7	million)	in	
contracted	services,	$3.6	million	(2020	-	$3.8	million)	in	materials	and	consumables,	$2.2	million	(2020	-	$2.2	million)	in	utilities,	$1.7	
million	(2020	-	$2.1	million)	in	maintenance	costs,	and	$0.2	million	(2020	-	$0.2	million)	in	other	costs.	The	increase	in	cost	of	sales	
was	primarily	attributed	to	increase	in	depreciation	and	depletion	and	contracted	services.

3.	 General	and	administrative	expenses	for	2021	was	primarily	comprised	of	$17.0	million	(2020	-	$12.2	million)	with	respect	to	salaries	
and	consulting	fees,	$9.1	million	(2020	-	$7.1	million)	in	office	and	sundry	expenses,	$7.1	million	(2020	-	$6.1	million)	in	incentive	
payments,	$3.3	million	(2020	-	$1.2	million)	in	travel-related	costs,	and	$1.6	million	(2020	-	$1.1	million)	in	professional	fees.	The	
increase	 in	 general	 and	 administrative	 expenses	 in	 2021	 was	 primarily	 attributable	 to	 an	 increase	 in	in	 corporate	 headcount	 and	
administrative	 activities	 to	 support	 overall	 growth	 in	 operations,	 as	 well	 as	 to	 enhance	 governance	 and	 compliance	 with	 the	
Company's	 recent	 NYSE	 listing.	 In	 addition,	 2021	 saw	 the	 resumption	 of	 travel	 activities	 which	 was	 restricted	 during	 the	 onset	 of	
COVID-19	in	early	2020.

Finance	expense	for	2021	was	$12.2	million	(2020	-	$15.4	million)	and	was	primarily	comprised	of	interest	on	loans	at	the	corporate	
head	office	of	$4.4	million	(2020	-	$6.7	million),	other	finance	expense	of	$3.4	million	(2020	-	$1.2	million),	accretion	of	the	asset	
retirement	obligations	of	$1.1	million	(Fiscal	2020	-	$0.9	million),	accretion	of	deferred	revenue	of	$1.5	million	(2020	-	$nil),	interest	
on	loans	and	borrowings	at	MCSA	and	NX	Gold	of	$0.8	million	(2020	-	$3.2	million),	commitment	fees	of	$1.0	million	(2020	-	$0.5	
million),	lease	interest	of	$0.4	million	(2020	-	$0.2	million),	and	gain	on	interest	rate	swap	derivatives	of	$0.5	million	(2020	-	$2.7	
million	loss).

Foreign	exchange	loss	for	2021	was	$22.0	million	(2020	-	$79.8	million	loss).	This	amount	was	primarily	comprised	of	realized	foreign	
exchange	loss	on	derivative	contracts	of	$22.2	million	(2020	-	$20.8	million	loss)	and	a	foreign	exchange	loss	on	USD	denominated	
debt	 of	 $5.4	 million	 (2020	 -	 $24.2	 million	 loss)	 in	 MCSA	 for	 which	 the	 functional	 currency	 is	 the	 BRL,	 partially	 offset	 by	 foreign	
exchange	gain	on	unrealized	derivative	contracts	of	$3.9	million	(2020	-	$34.5	million	loss)	and	an	increase	in	other	exchange	gains.	
The	fluctuation	in	foreign	exchange	gains/losses	were	primarily	a	result	of	increased	volatility	of	the	USD/BRL	foreign	exchange	rates.	
During	 2021,	 the	 BRL	 weakened	 7%	 against	 the	 USD.	 The	 foreign	 exchange	 gains/losses	 on	 unrealized	 derivative	 contracts	 are	 a	
result	of	mark-to-market	calculations	at	period	end	and	may	not	represent	the	amount	that	will	ultimately	be	realized,	which	will	
depend	on	future	changes	to	the	USD/BRL	foreign	exchange	rates.

In	2020,	the	Company	recognized	a	recovery	of	$8.9	million	in	net	income	related	to	value	added	taxes.	The	recovery	was	recognized	
as	 a	 result	 of	 a	 study	 conducted	 to	 revisit	 certain	 tax	 positions	 which	 concluded	 that	 it	 is	 probable	 that	 additional	 tax	 credits	 are	
available	to	be	used	to	offset	a	variety	of	taxes.	

In	 2021,	 the	 Company	 recognized	 a	 $34.3	 million	 income	 tax	 expense	 (2020	 -	 income	 tax	 expense	 of	 $8.9	 million),	 primarily	
comprised	of	current	tax	arising	from	an	increase	in	taxable	income	in	mining	operations.	

The	foreign	currency	translation	income/loss	is	a	result	of	weakening	of	the	BRL	against	the	USD	during	2021	when	translating	the	
net	assets	of	the	Company’s	Brazilian	subsidiaries	to	USD	for	presentation	in	the	Company’s	consolidated	financial	statements.

During	 Q4	 2021,	 the	 Company	 recognized	 net	 income	 of	 $60.2	 million	 compared	 to	 $26.4	 million	 in	 the	 preceding	 quarter.	 The	
increase	was	primarily	attributable	to	a	$16.4	million	increase	in	gross	profit	as	a	result	of	increased	copper	sales	volume,	as	well	as	a	
$15.2	 million	 decrease	 in	 foreign	 exchange	 losses	 as	 the	 BRL	 depreciation	 against	 the	 USD	 was	 relatively	 less	 than	 the	 preceding	
quarter.

During	 Q3	 2021,	 the	 Company	 recognized	 net	 income	 of	 $26.4	 million	 compared	 to	 $84.0	 million	 in	 the	 preceding	 quarter,	 a	
decrease	of	$58.7	million	primarily	due	to	volatility	in	foreign	exchange	gains	or	losses	driven	by	the	weakening	of	the	BRL	against	
the	USD	in	the	quarter,	resulting	in	$19.6	million	of	foreign	exchange	losses	compared	to	foreign	exchange	gains	of	$30.7	million	in	
the	preceding	quarter.

During	 Q2	 2021,	 the	 Company	 recognized	 $30.7	 million	 in	 foreign	 exchange	 gains.	 This	 amount	 is	 primarily	 comprised	 of	 foreign	
exchange	gain	on	unrealized	derivative	contracts	of	$29.9	million,	foreign	exchange	gain	on	USD	denominated	debt	of	$10.0	million	
in	MCSA	for	which	the	functional	currency	is	the	BRL,	partially	offset	by	realized	foreign	exchange	loss	on	derivative	contracts	of	$6.0	
million,	and	other	foreign	exchange	losses	of	$3.2	million.	The	foreign	exchange	gains	were	primarily	a	result	of	a	strengthening	of	
BRL	against	USD	in	Q2	2021	as	compared	to	the	prior	quarter.	The	foreign	exchange	gains	on	unrealized	derivative	contracts	are	a	
result	of	mark-to-market	calculations	at	period	end	and	may	not	represent	the	amount	that	will	ultimately	be	realized,	which	will	
depend	on	future	changes	to	the	USD/BRL	foreign	exchange	rates.

During	 Q4	 2020,	 the	 Company	 recognized	 $27.1	 million	 in	 foreign	 exchange	 gains.	 The	 foreign	 exchange	 gains	 were	 primarily	
comprised	 of	 foreign	 exchange	 gain	 on	 unrealized	 derivative	 contracts	 of	 $27.7	 million	 and	 a	 foreign	 exchange	 gain	 on	 USD	
denominated	debt	of	$7.7	million	in	MCSA	for	which	the	functional	currency	is	the	BRL,	partially	offset	by	a	realized	foreign	exchange	
loss	 on	 derivative	 contracts	 of	 $7.8	 million	 and	 other	 foreign	 losses	 of	 $0.4	 million.	 The	 foreign	 exchange	 gains	 were	 primarily	 a	
result	of	a	strengthening	of	BRL	against	USD	in	Q4	2020.	The	foreign	exchange	gains	on	unrealized	derivative	contracts	are	a	result	of	
mark-to-market	calculations	at	period	end	and	may	not	represent	the	amount	that	will	ultimately	be	realized,	which	will	depend	on	
future	changes	to	the	USD/BRL	foreign	exchange	rates.	

During	the	quarter	ended	December	31,	2020,	the	Company	recognized	a	recovery	of	$8.9	million	in	net	income	related	to	value	
added	taxes.	The	recovery	was	recognized	as	a	result	of	a	study	conducted	to	revisit	certain	tax	positions	which	concluded	that	it	is

During	Q2	2020,	the	Company	had	an	overall	net	income	of	$7.7	million,	despite	$16.3	million	in	foreign	exchange	losses.	The	foreign

on	realized	derivative	contracts	of	$4.4	million,	and	a	foreign	exchange	loss	on	USD	denominated	debt	of	$3.0	million	in	MCSA	for	
which	the	functional	currency	is	the	BRL.	As	with	the	preceding	quarter,	the	foreign	exchange	losses	were	unusually	high	this	quarter	
due	to	volatility	in	the	foreign	exchange	rates	between	the	USD	and	BRL	resulting	from	the	worldwide	instability	in	currency	rates	as	
a	result	of	the	COVID-19	pandemic.

6.

During	the	quarter	ended	March	31,	2020,	the	Company	recognized	a	$81.9	million	in	foreign	exchange	losses.	The	foreign	exchange	
losses	 were	 mainly	 comprised	 of	 a	 $26.9	 million	 loss	 associated	 with	 USD	 denominated	 debt	 held	 by	 MCSA,	 whose	 functional	
currency	is	the	BRL,	and	$52.7	million	losses	associated	with	unrealized	losses	on	foreign	exchange	currency	collar	contracts.	These	
foreign	exchange	losses	were	unusually	high	this	quarter	due	to	volatility	in	the	foreign	exchange	rates	between	the	USD	and	the	BRL

LIQUIDITY,	CAPITAL	RESOURCES,	AND	CONTRACTUAL	OBLIGATIONS

Liquidity

As	at	December	31,	2021,	the	Company	held	cash	and	cash	equivalents	of	$130.1	million	which	were	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	have	increased	by	$67.6	million	since	December	31,	2020.	The	Company’s	cash	flows	
from	operating,	investing,	and	financing	activities	during	2021	are	summarized	as	follows:

Capital	Resources

The	Company’s	primary	sources	of	capital	are	comprised	of	cash	from	operations,	cash	and	cash	equivalents	on	
hand	 and	 short-term	 investments.	 The	 Company	 continuously	 monitors	 its	 liquidity	 position	 and	 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.	 Taking	 into	 consideration	 cash	 flow	 from	 existing	 operations,	
management	 believes	 that	 the	 Company	 has	 sufficient	 working	 capital	 and	 financial	 resources	 to	 maintain	 its	
planned	operations	and	activities	for	the	foreseeable	future.

At	December	31,	2021,	the	Company	had	available	liquidity	of	$230.1	million,	including	$130.1	million	in	cash	
and	cash	equivalents	and	$100.0	million	of	undrawn	availability	under	its	$150	million	senior	secured	revolving	
credit	facility.

The	Company	ended	the	year	with	unrestricted	cash	and	cash	equivalents	of	$130.1	million	compared	to	$62.5	
million	at	December	31,	2020.	The	increase	is	primarily	due	to	an	increase	in	cash	from	mining	operations	and	a	
$100.0	million	upfront	payment	from	the	NX	Gold	Transaction.	

At	December	31,	2020,	the	Company	had	a	$150.0	million	credit	facility	from	a	syndicate	of	Canadian	financial	
institutions.	 The	 credit	 facility	 was	 comprised	 of	 $75.0	 million	 in	 senior	 secured	 non-revolving	 credit	 facility	
(“Term	 Facility”)	 and	 a	 $75.0	 million	 senior	 secured	 revolving	 credit	 facility	 (“Revolving	 Credit	 Facility”)	
(collectively,	 the	 "Old	 Facilities).	 The	 Term	 Facility	 was	 to	 mature	 on	 March	 31,	 2024	 and	 required	 principal	
repayments	on	a	quarterly	basis	commencing	on	March	31,	2022,	while	the	Revolving	Credit	Facility	was	payable	
in	full	at	maturity	on	March	31,	2024.	The	Old	Facilities	bore	interest	on	a	sliding	scale	at	a	rate	of	LIBOR	plus	
2.50%	to	4.25%,	depending	on	the	Company’s	consolidated	leverage	ratio.

During	the	year	ended	December	31,	2021,	the	Old	Facilities	were	amended	and	combined	into	a	new	$150.0	
million	senior	secured	revolving	credit	facility	(“New	Revolving	Credit	Facility”)	with	maturity	date	of	March	31,	
2025.	The	New	Revolving	Credit	Facility	bears	interest	on	a	sliding	scale	at	a	rate	of	LIBOR	plus	2.25%	to	4.25%	
depending	 on	 the	 Company’s	 consolidated	 leverage	 ratio.	 Commitment	 fees	 for	 any	 undrawn	 portion	 of	 the	
New	Revolving	Credit	Facility	are	on	a	sliding	scale	between	0.56%	to	1.06%

During	the	year,	the	Company	used	its	cash	on	hand,	bolstered	by	proceeds	from	the	NX	Gold	Transaction,	to	
repay	$100.0	million	of	principal	on	its	$150.0	million	senior	secured	revolving	credit	facility.	As	of	December	31,	
2021,	$50.0	million	was	drawn	on	the	New	Revolving	Credit	Facility.	The	Company	is	required	to	comply	with	
certain	 financial	 covenants.	 As	 of	 the	 date	 of	 the	 consolidated	 financial	 statements,	 the	 Company	 is	 in	
compliance	with	these	covenants.	

The	New	Revolving	Credit	Facility	includes	standard	and	customary	terms	and	conditions	with	respect	to	fees,	
representations,	warranties,	and	financial	covenants	that	remain	unchanged	from	those	of	the	Facilities.

In	February	2022,	the	Company	closed	an	offering	of	$400	million	aggregate	principal	amount	of	Senior	Notes	
due	 2030	 (the	 “Notes”).	 Interest	 on	 the	 Notes	 accrues	 at	 an	 annual	 rate	 of	 6.50%,	 payable	 semi-annually	 in	
arrears.	The	Notes	mature	on	February	15,	2030.		MCSA	is	currently	the	only	guarantor	of	the	Notes	on	a	senior	
unsecured	basis.	The	Notes	are	direct,	senior	obligations	of	the	Company	and	MCSA,	and	are	not	secured	by	any	
mortgage,	pledge	or	charge.	Estimated	transaction	costs	related	to	the	offering	of	the	Notes	was	$8.5	million.	

Pursuant	to	closing	of	the	Notes	offering,	the	Company	repaid	the	outstanding	balance	under	its	New	Revolving	
Credit	Facility	of	approximately	$50	million	and	reduced	the	size	of	its	New	Revolving	Senior	Credit	Facility	from	
$150	 million	 to	 $75	 million,	 with	 an	 accordion	 option	 to	 increase	 to	 $100.0	 million	 at	 the	 election	 of	 the	
Company.

Contractual	Obligations	and	Commitments

Certain	loan	agreements	contain	operating	and	financial	covenants	that	could	restrict	the	ability	of	the	Company	
and	 its	 subsidiaries,	 MCSA,	 Ero	 Gold,	 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.

In	August	2021,	the	Company	completed	the	closing	of	a	precious	metals	purchase	agreement	with	Royal	Gold	
whereby	 the	 Company	 is	 obligated	 to	 sell	 a	 portion	 of	 its	 gold	 production	 from	 the	 NX	 gold	 mine	 at	 contract	
prices	(see	"NX	Gold	Transaction"	section	in	this	MD&A	for	further	information).	

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.

COVID-19	Pandemic	risk

COVID-19	 continues	 to	 have	 a	 significant	 impact	 on	 the	 volatility	 of	 commodity	 prices	 and	 USD/BRL	 exchange	
rates,	and	governmental	actions	to	contain	COVID-19	and	mutations	thereto	may	impact	our	ability	to	transport	
or	 market	 our	 concentrate	 or	 cause	 disruptions	 in	 our	 supply	 chains	 or	 interruption	 of	 production.	 A	 material	
spread	 of	 COVID-19	 and	 mutations	 thereto	 in	 jurisdictions	 where	 we	 operate	 could	 impact	 our	 ability	 to	 staff	
operations.	 A	 reduction	 in	 production	 or	 other	 COVID-19	 related	 impacts,	 including	 but	 not	 limited	 to,	 low	
copper	prices	could	cause	a	significant	reduction	in	profitability	of	ongoing	operations.

New	waves	of	COVID-19	and	mutations	thereto	could	cause	temporary	closure	of	businesses	in	regions	that	are	
significantly	 impacted	 by	 the	 health	 crises,	 or	 cause	 governments	 to	 take	 or	 continue	 to	 take	 preventative	
measures	such	as	imposing	entry	restrictions	at	or	the	closure	of	points	of	entry,	including	ports	and	borders.	

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,	
2021	and	December	31,	2020:

The	Company	invests	cash	and	cash	equivalents	and	short-term	investments	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

five	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,	2021	and	2020	nor	recognized	a	provision	for	credit	
losses.	

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,	 2021	 relates	 to	 $7.8	 million	
(December	31,	2020	–	$7.4	million)	in	loans	and	borrowings	of	MCSA	denominated	in	US	dollars	and	Euros.	In	
addition,	the	Company	is	also	exposed	to	foreign	exchange	currency	risk	at	December	31,	2021	on	$63.8	million	
due	 to	 an	 intercompany	 loan	 balance	 (December	 31,	 2020	 -	 $83.1	 million)	 which	 has	 contractual	 repayment	
terms.	Strengthening	(weakening)	in	the	Brazilian	Real	against	the	US	dollar	at	December	31,	2021	by	10%	and	
20%,	would	have	increased	(decreased)	pre-tax	net	income	by	$7.0	million	and	$13.9	million,	respectively	(2020	
–	$8.9	million	and	$17.7	million).	Strengthening	(weakening)	in	the	Brazilian	Real	against	the	Euro	at	December	
31,	 2021	 by	 10%	 and	 20%,	 would	 have	 increased	 (decreased)	 pre-tax	 net	 income	 by	 $0.2	 million	 and	 $0.4	
million,	 respectively	 (2020	 –	 $0.2	 million	 and	 $0.4	 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,	2021,	the	Company	has	entered	into	foreign	exchange	collar	contracts	at	zero	cost	for	
notional	amounts	of	$179.5	million	(December	31,	2020	-	notional	amount	of	$285.7	million)	with	an	average	
floor	rate	of	4.24	BRL	to	US	Dollar	and	an	average	cap	rate	of	4.76	BRL	to	US	Dollar.	The	maturity	dates	of	these	
contracts	are	from	January	3,	2022	to	December	28,	2022	and	are	financially	settled	on	a	net	basis.	The	fair	value	
of	 these	 contracts	 at	 December	 31,	 2021	 was	 a	 liability	 of	 $28.7	 million,	 (December	 31,	 2020	 -	 $34.5	 million)	
which	is	included	in	Derivatives	in	the	statement	of	financial	position.	The	fair	value	of	these	forward	contracts	
as	 at	 December	 31,	 2021	 was	 determined	 using	 an	 option	 pricing	 model	 with	 the	 following	 assumptions:	
discount	 rate	 of	 2.74%	 -	 2.80%,	 foreign	 exchange	 rate	 of	 approximately	5.59—6.17,	 and	 volatility	 of	 15.69%	 -	
17.92%.	

The	 change	 in	 fair	 value	 of	 foreign	 exchange	 collar	 contracts	 was	 a	 gain	 of	 $3.9	 million	 for	 the	 year	 ended	
December	31,	2021	(a	loss	of	$34.5	million	for	the	year	ended	December	31,	2020)	and	has	been	recognized	in	
foreign	 exchange	 loss.	 In	 addition,	 during	 the	 year	 ended	 December	 31,	 2021,	 the	 Company	 recognized	 a	
realized	loss	of	$22.2	million	(realized	loss	of	$20.8	million	for	the	year	ended	December	31,	2020)	related	to	the	
settlement	of	foreign	currency	forward	collar	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	New	Revolving	Credit	Facility	of	$50.0	million	
and	Brazilian	Real	denominated	bank	loans	of	$3.5	million.	Based	on	the	Company’s	net	exposure	at	December	
31,	2021,	a	1%	change	in	the	variable	rates	would	have	an	impact	of	$0.5	million	on	pre-tax	annual	net	income,	
without	consideration	of	the	effects	of	the	interest	rate	swap	contract	below.

In	order	to	mitigate	the	above	volatility	due	to	variable	rates	on	loans,	December	31,	2021the	Company	entered	
into	an	interest	rate	swap	contract	to	manage	interest	rate	risk.	At	December	31,	2021,	the	floating	interest	on	a	
notional	 amount	 of	 $50.0	 million	 was	 swapped	 for	 a	 fixed	 interest	 rate	 of	 1.68%.	 This	 interest	 rate	 swap	
transaction	is	in	effect	until	March	31,	2025,	with	settlements	made	on	a	monthly	basis.	The	fair	value	of	this	
contract	 at	 December	 31,	 2021	 was	 a	 liability	 of	 $1.0	 million	 (December	 31,	 2020	 -	 $2.5	 million)	 and	 was	
included	in	Derivatives	in	the	statement	of	financial	position.	

For	the	year	ended	December	31,	2021,	the	Company	recognized	a	realized	loss	of	$0.8	million	(a	realized	loss	of	
$1.6	million	for	the	year	ended	December	31,	2020)	and	an	unrealized	gain	of	$1.3	million	(an	unrealized	loss	of	
$1.1	million	for	the	year	ended	December	31,	2020),	respectively,	in	relation	to	its	interest	rate	swap	derivatives.

Price	risk	

The	 Company	 may	 use	 derivatives,	 including	 forward	 contracts,	 collars	 and	 swap	 contracts,	 to	 manage	
commodity	price	risks.	At	December	31,	2021,	the	Company	has	provisionally	priced	sales	that	are	exposed	to	
commodity	price	changes.	Based	on	the	Company’s	net	exposure	at	December	31,	2021,	a	10%	change	in	the	
price	of	copper	would	have	an	impact	of	$0.2	million	on	pre-tax	net	income.

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,	2021	(the	“AIF”).

OTHER	FINANCIAL	INFORMATION

Off-Balance	Sheet	Arrangements

As	at	December	31,	2021,	the	Company	had	no	material	off-balance	sheet	arrangements.	

Contingencies

Due	 to	 the	 nature	 of	 the	 Company’s	 operations,	 various	 legal,	 tax,	 environmental	 and	 regulatory	 matters	 are	
outstanding	 from	 time	 to	 time.	 By	 their	 nature,	 contingencies	 will	 only	 be	 resolved	 when	 one	 or	 more	 future	
events	 occur	 or	 fail	 to	 occur.	 The	 assessment	 of	 contingencies	 inherently	 involves	 the	 exercise	 of	 significant	
judgement	and	estimates	of	the	outcome	of	future	events.	While	the	outcomes	of	these	matters	are	uncertain,	
based	upon	the	information	currently	available,	the	Company	does	not	believe	that	these	matters	in	aggregate	
will	 have	 a	 material	 adverse	 effect	 on	 its	 consolidated	 financial	 statements.	 In	 the	 event	 that	 management’s	
estimate	 of	 the	 future	 resolution	 of	 these	 matters	 changes,	 the	 Company	 will	 recognize	 the	 effect	 of	 these	
changes	in	its	consolidated	financial	statements	in	the	period	in	which	such	changes	occur.	

MCSA	is	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	$21.0	million	as	at	December	31,	2021	(December	31,	2020	
-	$21.8	million),	which	could	have	an	adverse	impact	on	the	Company’s	business,	financial	condition,	results	of	
operations,	cash	flows	or	prospects.

Outstanding	Share	Data

As	of	March	8,	2022,	the	Company	had	90,234,378	common	shares	issued	and	outstanding.	

Related	Party	Disclosures

For	the	year	ended	December	31,	2021,	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.	

Related	party	transactions	are	disclosed	in	the	consolidated	financial	statements	for	the	year	ended	December	
31,	2021.

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	
consolidated	 financial	 statements	 for	 the	 year	 ended	 December	 31,	 2021.	 Certain	 of	 these	 policies,	 such	 as	
deferred	 revenue,	 capitalization	 and	 depreciation	 of	 property,	 plant	 and	 equipment	 and	 mining	 interests,	
derivative	instruments,	mine	reclamation	and	closure	costs,	decommissioning	liabilities	provisions	and	income	
taxes	 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.	Actual	
results	may	differ	from	these	estimates.

Management	 continuously	 reviews	 its	 estimates,	 judgments	 and	 assumptions	 on	 an	 ongoing	 basis	 using	 	 the	
most	current	information	available.	Revisions	to	estimates	are	recognized	prospectively.

ALTERNATIVE	PERFORMANCE	(NON-IFRS)	MEASURES

The	Company	utilizes	certain	alternative	performance	(non-IFRS)	measures	to	monitor	its	performance,	including	
C1	cash	cost	of	copper	produced	(per	lb),	C1	cash	cost	of	gold	produced	(per	ounce),	AISC	of	gold	produced	(per	
ounce),	realized	gold	price	(per	ounce),	EBITDA,	adjusted	EBITDA,	adjusted	net	income	attributable	to	owners	of	
the	 Company,	 adjusted	 net	 income	 per	 share,	 net	 (cash)	 debt,	 working	 capital	 and	 available	 liquidity.	 These	
performance	 measures	 have	 no	 standardized	 meaning	 prescribed	 within	 generally	 accepted	 accounting	
principles	under	IFRS	and,	therefore,	amounts	presented	may	not	be	comparable	to	similar	measures	presented	
by	 other	 mining	 companies.	 These	 non-IFRS	 measures	 are	 intended	 to	 provide	 supplemental	 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	reconciliations	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	a	non-IFRS	performance	measure	used	by	the	Company	to	manage	
and	evaluate	the	operating	performance	of	its	copper	mining	segment	and	is	calculated	as	C1	cash	costs	divided	
by	 total	 pounds	 of	 copper	 produced	 during	 the	 period.	 C1	 cash	 costs	 includes	 total	 cost	 of	 production,	
transportation,	 treatment	 and	 refining	 charges,	 and	 certain	 tax	 credits	 relating	 to	 sales	 invoiced	 to	 the	
Company's	Brazilian	customer	on	sales,	net	of	by-product	credits	and	incentive	payments.	C1	cash	cost	of	copper	
produced	per	pound	is	widely	reported	in	the	mining	industry	as	benchmarks	for	performance	but	does	not	have	
a	standardized	meaning	and	is	disclosed	in	supplement	to	IFRS	measures.	

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

C1	Cash	Cost	of	Gold	produced	(per	ounce)	and	AISC	of	Gold	produced	(per	ounce)	

C1	cash	cost	of	gold	produced	(per	ounce)	is	a	non-IFRS	performance	measure	used	by	the	Company	to	manage	
and	evaluate	the	operating	performance	of	its	gold	mining	segment	and	is	calculated	as	C1	cash	costs	divided	by	
total	 ounces	 of	 gold	 produced	 during	 the	 period.	 C1	 cash	 cost	 includes	 total	 cost	 of	 production,	 net	 of	 by-
product	 credits	 and	 incentive	 payments.	 C1	 cash	 cost	 of	 gold	 produced	 per	 ounce	 is	 widely	 reported	 in	 the	
mining	industry	as	benchmarks	for	performance	but	does	not	have	a	standardized	meaning	and	is	disclosed	in	
supplemental	to	IFRS	measures.	

AISC	of	gold	produced	(per	ounce)	is	an	extension	of	C1	cash	cost	of	gold	produced	(per	ounce)	discussed	above	
and	 is	 also	 a	 key	 performance	 measure	 used	 by	 management	 to	 evaluate	 operating	 performance	 of	 its	 gold	
mining	 segment.	 AISC	 of	 gold	 produced	 (per	 ounce)	 is	 calculated	 as	 AISC	 divided	 by	 total	 ounces	 of	 gold	
produced	during	the	period.	AISC	includes	C1	cash	costs,	site	general	and	administrative	costs,	accretion	of	mine	
closure	 and	 rehabilitation	 provision,	 sustaining	 capital	 expenditures,	 sustaining	 leases,	 and	 royalties	 and	
production	taxes.	AISC	of	gold	produced	(per	ounce)	is	widely	reported	in	the	mining	industry	as	benchmarks	for	
performance	but	does	not	have	a	standardized	meaning	and	is	disclosed	in	supplement	to	IFRS	measures.

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

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

“Adjusted	 net	 income	 attributable	 to	 owners	 of	 the	 Company”	 is	 net	 income	 attributed	 to	 shareholders	 as	
reported,	adjusted	for	certain	types	of	transactions	that,	in	management's	judgment,	are	not	indicative	of	our	
normal	 operating	 activities	 or	 do	 not	 necessarily	 occur	 on	 a	 recurring	 basis.	 “Adjusted	 net	 income	 per	 share	
attributable	to	owners	of	the	Company”	(“Adjusted	EPS”)	is	calculated	as	"adjusted	net	income	attributable	to	
owners	of	the	Company"	divided	by	weighted	average	number	of	outstanding	common	shares	in	the	period.	The	
Company	believes	that,	in	addition	to	conventional	measures	prepared	in	accordance	with	IFRS,	the	Company	
and	 certain	 investor	 and	 analysts	 use	 these	 supplemental	 non-IFRS	 performance	 measures	 to	 evaluate	 the	
normalized	performance	of	the	Company.	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	reconciliation	of	Adjusted	net	income	attributable	to	owners	of	the	Company	and	
Adjusted	 EPS	 to	 net	 income	 attributable	 to	 the	 owners	 of	 the	 Company,	 its	 most	 directly	 comparable	 IFRS	
measure.

Disclosure	Controls	and	Procedures	and	Internal	Control	over	Financial	Reporting

The	 Company’s	 management,	 with	 the	 participation	 of	 the	 CEO	 and	 CFO,	 is	 responsible	 for	 establishing	 and	
maintaining	adequate	disclosure	controls	and	procedures	(“DC&P”)	and	internal	control	over	financial	reporting	
(“ICFR”)	 using	 Internal	 Control	 –	 Integrated	 Framework	 (2013)	 issued	 by	 the	 Committee	 of	 Sponsoring	
Organizations	of	the	Treadway	Commission	("COSO")	as	its	internal	control	framework.	

The	 Company’s	 DC&P	 are	 designed	 to	 provide	 reasonable	 assurance	 that	 material	 information	 related	 to	 the	
Company	is	identified	and	communicated	on	a	timely	basis.	

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.	

As	required	by	National	Instrument	52-109,	Certification	of	Disclosure	in	Issuers'	Annual	and	Interim	Filings,	the	
Company’s	management	conducted	an	evaluation	of	the	design	and	operating	effectiveness	of	the	Company’s	
DC&P	and	ICFR	and	concluded	that	the	Company’s	DC&P	and	ICFR	were	effective	as	of	December	31,	2021.

There	 were	 no	 changes	 in	 the	 Company’s	 DC&P	 and	 ICFR	 that	 materially	 affected,	 or	 are	 reasonably	 likely	 to	
materially	affect,	ICFR	during	the	year	ended	December	31,	2021.

Forward-looking	 statements	 are	 subject	 to	 a	 variety	 of	 known	 and	 unknown	 risks,	 uncertainties	 and	 other	
factors	that	could	cause	actual	results,	actions,	events,	conditions,	performance	or	achievements	to	materially

arrangements.	Although	the	Company	believes	that	the	assumptions	inherent	in	forward-looking	statements	are	
reasonable	as	of	the	date	of	this	MD&A,	these	assumptions	are	subject	to	significant	business,	social,	economic,

cause	actual	actions,	events,	conditions,	results,	performance	or	achievements	to	be	materially	different	from	
those	projected	in	the	forward-looking	statements.	The	Company	cautions	that	the	foregoing	list	of	assumptions	
is	 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	statements	contained	in	this	MD&A.

Forward-looking	statements	contained	herein	are	made	as	of	the	date	of	this	MD&A	and	the	Company	disclaims	
any	 obligation	 to	 update	 or	 revise	 any	 forward-looking	 statement,	 whether	 as	 a	 result	 of	 new	 information,

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	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”).	NI	43-101	is	a	rule	developed	by	the	Canadian	Securities	Administrators	that	establishes	
standards	 for	 all	 public	 disclosure	 an	 issuer	 makes	 of	 scientific	 and	 technical	 information	 concerning	 mineral	
projects.	 NI	 43-101	 differs	 significantly	 from	 the	 disclosure	 requirements	 of	 the	 Securities	 and	 Exchange	
Commission	 (the	 “SEC”)	 generally	 applicable	 to	 U.S.	 companies.	 For	 example,	 the	 terms	 “mineral	 reserve”,	
“proven	 mineral	 reserve”,	 “probable	 mineral	 reserve”,	 “mineral	 resource”,	 “measured	 mineral	 resource”,	
“indicated	mineral	resource”	and	“inferred	mineral	resource”	are	defined	in	NI	43-101.	These	definitions	differ	
from	the	definitions	in	the	disclosure	requirements	promulgated	by	the	SEC.	Accordingly,	information	contained	
in	this	MD&A	may	not	be	comparable	to	similar	information	made	public	by	U.S.	companies	reporting	pursuant	
to	SEC	disclosure	requirements.	

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.

Report	of	Independent	Registered	Public	Accounting	Firm

To	the	Stockholders	and	Board	of	Directors	
Ero	Copper	Corp.

Opinion	on	the	Consolidated	Financial	Statements

We	have	audited	the	accompanying	consolidated	statements	of	financial	position	of	Ero	Copper	Corp.	(the	Company)	as	of	
December	31,	2021	and	2020,	the	related	consolidated	statements	of	operations	and	comprehensive	income,	cash	flows	
and	changes	in	shareholders’	equity	for	the	years	then	ended,	and	the	related	notes	(collectively,	the	consolidated	financial	
statements).	 In	 our	 opinion,	 the	 consolidated	 financial	 statements	 present	 fairly,	 in	 all	 material	 respects,	 the	 financial	
position	 of	 the	 Company	 as	 of	 December	 31,	 2021	 and	 2020,	 and	 the	 results	 of	 its	 operations	 and	 its	 cash	 flows	 for	 the	
years	then	ended,	in	conformity	with	International	Financial	Reporting	Standards	as	issued	by	the	International	Accounting	
Standards	Board.

Basis	for	Opinion

These	 consolidated	 financial	 statements	 are	 the	 responsibility	 of	 the	 Company’s	 management.	 Our	 responsibility	 is	 to	
express	 an	 opinion	 on	 these	 consolidated	 financial	 statements	 based	 on	 our	 audits.	 We	 are	 a	 public	 accounting	 firm	
registered	 with	 the	 Public	 Company	 Accounting	 Oversight	 Board	 (United	 States)	 (PCAOB)	 and	 are	 required	 to	 be	
independent	with	respect	to	the	Company	in	accordance	with	the	U.S.	federal	securities	laws	and	the	applicable	rules	and	
regulations	of	the	Securities	and	Exchange	Commission	and	the	PCAOB.

We	 conducted	 our	 audits	 in	 accordance	 with	 the	 standards	 of	 the	 PCAOB.	 Those	 standards	 require	 that	 we	 plan	 and	
perform	the	audit	to	obtain	reasonable	assurance	about	whether	the	consolidated	financial	statements	are	free	of	material	
misstatement,	 whether	 due	 to	 error	 or	 fraud.	 Our	 audits	 included	 performing	 procedures	 to	 assess	 the	 risks	 of	 material	
misstatement	 of	 the	 consolidated	 financial	 statements,	 whether	 due	 to	 error	 or	 fraud,	 and	 performing	 procedures	 that	
respond	 to	 those	 risks.	 Such	 procedures	 included	 examining,	 on	 a	 test	 basis,	 evidence	 regarding	 the	 amounts	 and	
disclosures	in	the	consolidated	financial	statements.	Our	audits	also	included	evaluating	the	accounting	principles	used	and	
significant	 estimates	 made	 by	 management,	 as	 well	 as	 evaluating	 the	 overall	 presentation	 of	 the	 consolidated	 financial	
statements.	We	believe	that	our	audits	provide	a	reasonable	basis	for	our	opinion.

Ero	Copper	Corp.	(“Ero"	or	the	"Company")	was	incorporated	on	May	16,	2016	under	the	Business	Corporations	Act	(British	
Columbia)	and	maintains	its	head	office	at	Suite	1050,	625	Howe	Street,	Vancouver,	BC,	V6C	2T6.	The	Company’s	shares	are	
publicly	traded	on	the	Toronto	Stock	Exchange	and	the	New	York	Stock	Exchange	under	the	symbol	“ERO”.

The	 Company’s	 principal	 asset	 is	 its	 99.6%	 ownership	 interest	 in	 Mineração	 Caraíba	 S.A.	 (“MCSA”).	 The	 Company	 also	
currently	owns	a	97.6%	ownership	interest	in	NX	Gold	S.A.	(“NX	Gold”)	indirectly	through	its	wholly-owned	subsidiary,	Ero	
Gold	Corp.	(“Ero	Gold”).		

MCSA	is	a	Brazilian	company	which	holds	a	100%	interest	in	the	MCSA	Mining	Complex	and	the	Boa	Esperança	Property	
(Note	8).	MCSA’s	predominant	activity	is	the	production	and	sale	of	copper	concentrate	from	the	MCSA	Mining	Complex,	
located	in	Bahia,	Brazil,	with	gold	and	silver	produced	and	sold	as	by-products.	The	Boa	Esperança	Property	is	located	within	
the	municipality	of	Tucumã	in	the	southeastern	part	of	the	state	of	Pará,	Brazil,	and	consists	of	a	single	mineral	concession	
covering	an	area	of	4,034	hectares	(“ha”).		

NX	Gold	is	a	Brazilian	gold	mining	company	focused	on	the	production	and	sale	of	gold	as	its	main	product	and	silver	as	its	
by-product.	 NX	 Gold	 wholly	 owns	 a	 31,096	 ha	 property,	 located	 approximately	 18	 kilometers	 west	 of	 the	 town	 of	 Nova	
Aventine,	in	southeastern	Mato	Grosso	State,	Brazil,	consisting	of	a	single	mining	concession	covering	an	area	of	620	ha,	
where	all	gold	mining	and	processing	activities	occur.				

The	 Company	 continues	 to	 have	 no	 material	 disruption	 to	 operations,	 supply	 chains	 or	 sales	 channels	 as	 a	 result	 of	 the	
COVID-19	 pandemic.	 Since	 the	 onset	 of	 the	 COVID-19	 in	 early	 2020,	 the	 Company	 has	 continued	 to	 take	 measures	 to	
mitigate	the	possible	impact	of	COVID-19	on	its	workforce	and	operations.	There	is	no	guarantee	that	this	will	continue	to	
be	 the	 case.	 The	 extent	 to	 which	 COVID-19	 will	 impact	 the	 Company’s	 workforce,	 operations,	 supply	 chains,	 or	 sales	
channels	will	depend	on	future	developments	which	are	uncertain	and	cannot	be	predicted	with	confidence.	These	impacts	
could	include	an	impact	on	the	Company’s	ability	to	obtain	equity	financing	and/or	additional	financing,	impairments	in	the	
value	of	long-lived	assets,	continued	fluctuation	in	the	value	of	the	Brazilian	Real	or	potential	future	decreases	in	revenue	or	
the	profitability	of	ongoing	operations.	

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	8,	2022.

(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.		

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

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

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.	

Certain	 comparative	 amounts	 have	 been	 reclassified	 to	 conform	 with	 the	 current	 year’s	 financial	 statement	
presentation.	Such	reclassifications	were	not	considered	material.	

(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	 judgments	 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	judgments	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:

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

Derivative	instruments

The	fair	value	of	derivative	instruments	is	determined	using	either	present	value	techniques	or	option	pricing	models	
that	 utilize	 a	 variety	 of	 inputs	 that	 are	 a	 combination	 of	 quoted	 prices	 and	 market-corroborated	 inputs,	 including	
assumptions	 for	 forward	 interest	 and	 foreign	 exchange	 rates,	 volatilities	 and	 discount	 rates.	 The	 fair	 value	 of	 the	
Company’s	derivative	contracts	includes	an	adjustment	for	credit	risk	for	either	the	Company	or	the	counter	party	as	
applicable.	Changes	in	the	assumptions	for	inputs	into	the	models	affect	the	fair	value	of	the	derivatives	recognized	in	
the	statement	of	financial	position	as	well	as	the	unrealized	gains	or	losses	recognized	in	net	income.		

Mineral	reserve	and	resource	estimates	including	life	of	mine	plan

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

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,	 property,	 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,	amortization	of	deferred	revenue,	and	may	also	result	in	impairment	charges	on	non-current	assets.

Mine	closure	and	reclamation	costs

Significant	estimates	and	assumptions	are	made	in	determining	the	provision	for	mine	closure	and	reclamation	costs	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,	
property,	 plant	 and	 equipment.	 Adjustments	 to	 the	 carrying	 amounts	 of	 related	 mineral,	 property,	 plant	 and	
equipment	can	result	in	a	change	to	future	depreciation	and	depletion	expense.

Income	taxes

The	 determination	 of	 the	 Company’s	 tax	 expense	 for	 the	 period	 and	 deferred	 tax	 assets	 and	 liabilities	 involves	
significant	 estimation	 and	 judgment	 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.

The	 Company	 operates	 in	 Brazil	 where	 tax	 authorities	 may	 audit	 income	 tax	 treatments	 and	 the	 resolution	 of	 such	
audits	may	span	multiple	years.	Tax	law	in	Brazil	is	complex	and	often	subject	to	changes	and	to	varied	interpretations;	
accordingly,	the	ultimate	outcome	with	respect	to	income	tax	treatments	may	differ	from	the	amounts	recognized.	The

Company’s	 assessment	 of	 whether	 it	 is	 probable	 that	 uncertain	 income	 tax	 treatments	 will	 be	 accepted	 by	 tax	
authorities	in	Brazil	is	a	significant	management	judgment.

Deferred	Revenue

Judgment	and	estimates	were	required	in	determining	the	accounting	for	the	precious	metal	purchase	agreement	with	
RGLD	Gold	AG,	a	subsidiary	of	Royal	Gold	Inc.	(collectively	"Royal	Gold"),	which	is	accounted	for	as	deferred	revenue	in	
accordance	with	IFRS	15	Revenue	from	Contracts	with	Customers	(“IFRS	15”).	As	the	Company’s	obligation	under	the	
precious	metal	purchase	agreement	will	be	satisfied	through	deliveries	of	a	non-financial	item	(i.e.	deliveries	of	gold	
ounces),	rather	than	cash	or	other	financial	assets,	it	was	determined	to	be	entered	into	and	continued	to	be	held	for	
the	 purpose	 of	 the	 delivery	 of	 a	 non-financial	 item	 in	 accordance	 with	 the	 Company’s	 expected	 sale	 or	 usage	
requirements	and	thus	not	within	the	scope	of	IFRS	9	Financial	Instruments	(“own	use	exemption”).	The	determination	
of	whether	the	own	use	exemption	applies	requires	management’s	judgements.

Each	period	management	estimates	the	cumulative	amount	of	the	deferred	revenue	obligation	that	has	been	satisfied	
and,	therefore,	recognized	as	revenue.	Key	inputs	into	the	estimate	of	the	amount	of	deferred	revenue	that	should	be	
recognized	include	the	following:

a.

b.

Future	 gold	 prices	 are	 used	 to	 estimate	 the	 expected	 total	 consideration	 to	 be	 received	 under	 the	 contract	
including	variable	consideration	and	is	used	as	the	stand	alone	selling	price	to	allocate	the	consideration	to	each	
ounce	of	gold	to	be	delivered	to	Royal	Gold,	and
Expected	 life	 of	 mine	 gold	 production	 and	 the	 timing	 thereof,	 which	 is	 estimated	 based	 on	 the	 approved	 life	 of	
mine	for	the	NX	Gold	mine	and	the	portion	of	mineral	resources	anticipated	to	be	converted	to	mineral	reserves.

(e)	 New	Accounting	Policies,	Standards	and	Interpretations

Property,	Plant	and	Equipment	-	Proceeds	before	Intended	Use

On	May	14,	2020,	the	IASB	published	a	narrow	scope	amendment	to	IAS	16	Property,	Plant	and	Equipment	-	Proceeds	
before	 Intended	 Use.	 The	 amendment	 prohibits	 deducting	 from	 the	 cost	 of	 property,	 plant	 and	 equipment	 amounts	
received	from	selling	items	produced	while	preparing	the	asset	for	its	intended	use.	Instead,	amounts	received	will	be	
recognized	as	sales	proceeds	and	related	cost	in	profit	or	loss.	The	effective	date	is	for	annual	periods	beginning	on	or	
after	January	1,	2022,	with	early	adoption	permitted.	The	Company	has	elected	to	early	adopt	this	standard	in	2021,	
which	did	not	have	a	material	impact	on	its	consolidated	financial	statements.

(f)	 Future	Changes	in	Accounting	Policies	Not	Yet	Effective	as	of	December	31,	2021

The	following	amendment	to	accounting	standards	has	been	issued	but	not	yet	adopted	in	the	financial	statements:

•

In	 September	 2019,	 the	 IASB	 issued	 first	 phase	 amendments	 IFRS	 9	 Financial	 Instruments,	 IAS	 39	 Financial	
Instruments:	 Recognition	 and	 Hedging,	 and	 IFRS	 7	 Financial	 Instrument	 Disclosures	 to	 address	 the	 financial	
reporting	 impact	 of	 the	 reform	 on	 interest	 rate	 benchmarks,	 such	 as	 the	 discontinuance	 of	 the	 interbank	
offered	 rates.	 Phase	 2	 of	 the	 Interest	 Rate	 Benchmark	 Reform	 refers	 to	 a	 global	 reform	 of	 interest	 rate	
benchmarks,	 which	 includes	 the	 replacement	 of	 some	 interbank	 offered	 rates	 (“LIBOR”)	 with	 alternative	
benchmark	rates.	Phase	2	amendments	require	the	effective	interest	rate	to	be	adjusted	when	accounting	for	
changes	 in	 the	 basis	 for	 determining	 the	 contractual	 cash	 flows	 of	 financial	 assets	 and	 liabilities	 that	 relate	
directly	 to	 this	 reform	 rather	 than	 applying	 modification	 accounting.	 In	 addition,	 the	 Phase	 2	 amendments	
require	 disclosures	 to	 assist	 users	 in	 understanding	 the	 effect	 of	 the	 reform	 on	 the	 Company’s	 financial	
instruments	and	risk	management	strategy.		

At	 December	 31,	 2021,	 Company	 had	 a	 $150.0	 million	 senior	 secured	 revolving	 credit	 facility,	 of	 which	
$50.0	 million	 was	 drawn,	 which	 bears	 interest	 on	 a	 sliding	 scale	 at	 a	 rate	 of	 LIBOR	 plus	 2.25%	 to	 4.25%	
depending	on	the	Company’s	consolidated	leverage	ratio.	The	Company	also	maintained	an	interest	rate	swap

contract	 on	 a	 notional	 amount	 of	 $50.0	 million,	 which	 was	 swapped	 for	 a	 fixed	 interest	 rate	 of	 1.68%.	
Subsequent	to	year	end,	the	senior	secured	revolving	credit	facility	was	fully	repaid	and	the	interest	rate	swap	
contracts	were	fully	settled.	There	is	currently	no	specific	timeline	on	when	the	use	of	LIBOR	will	cease,	but	
the	 switch	 to	 Secured	 Overnight	 Financing	 Rate	 (SOFR)	 is	 not	 expected	 to	 have	 a	 significant	 impact	 on	 the	
consolidated	financial	statements.	

•

In	May	2021,	the	IASB	issued	Deferred	Tax	related	to	Assets	and	Liabilities	Arising	from	a	Single	Transaction	
which	 amended	 IAS	 12,	 Income	 Taxes	 ("IAS	 12").	 The	 amendments	 narrowed	 the	 scope	 of	 the	 recognition	
exemption	 in	 IAS	 12,	 relating	 to	 the	 recognition	 of	 deferred	 tax	 assets	 and	 liabilities,	 so	 that	 it	 no	 longer	
applies	 to	 transactions	 that,	 on	 initial	 recognition,	 give	 rise	 to	 equal	 taxable	 and	 deductible	 temporary	
differences	 such	 as	 leases	 and	 reclamation	 and	 closure	 cost	 provisions.	 The	 amendments	 are	 effective	 for	
annual	 reporting	 periods	 beginning	 on	 or	 after	 January	 1,	 2023	 to	 transactions	 that	 occur	 on	 or	 after	 the	
beginning	 of	 the	 earliest	 comparative	 period	 presented.	 Earlier	 application	 is	 permitted.	 The	 Company	 is	
currently	assessing	the	impact	of	the	amendments	on	its	consolidated	financial	statements.

Significant	Accounting	Policies

(a) Revenue

Revenue	relating	to	the	sale	of	metals	is	recognized	at	the	point	the	customer	obtains	control	of	the	product	and	when	
the	Company	has	satisfied	its	performance	obligations.	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	doré	is	delivered	
to	a	location	designated	by	the	customer,	or	when	gold	credits	are	transferred	to	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.

Deferred	Revenue	(note	11)

In	 August	 2021,	 the	 Company	 received	 an	 upfront	 cash	 deposit	 in	 connection	 with	 a	 precious	 metal	 purchase	
agreement	with	Royal	Gold,	which	is	accounted	for	as	deferred	revenue	in	accordance	with	IFRS	15.	Deferred	revenue	
consists	of	payments	received	by	the	Company	in	consideration	for	future	commitments	to	deliver	an	amount	of	gold	
equivalent	 to	 a	 percentage	 of	 the	 gold	 produced	 from	 its	 NX	 Gold	 operations.	 As	 gold	 deliveries	 are	 made,	 the	
Company	 recognizes	 a	 portion	 of	 the	 deferred	 revenue	 as	 revenue,	 calculated	 on	 a	 per	 unit	 basis	 using	 the	 total	
number	of	gold	ounces	expected	to	be	delivered	over	the	life	of	the	mine.	The	current	portion	of	deferred	revenue	is	
based	on	deliveries	anticipated	over	the	next	twelve	months.

Interest	 expense	 on	 deferred	 revenue	 is	 recognized	 in	 finance	 costs	 as	 there	 is	 a	 significant	 financing	 component	
related	 to	 the	 precious	 metal	 purchase	 agreement,	 resulting	 from	 a	 difference	 in	 the	 timing	 of	 the	 upfront	
consideration	 received	 and	 delivery	 of	 the	 gold.	 The	 interest	 rate	 is	 determined	 based	 on	 the	 rate	 implicit	 in	 the	
precious	metal	purchase	agreement	at	the	date	of	inception.

Revenue	 to	 be	 recognized	 from	 the	 initial	 consideration	 received	 from	 the	 precious	 metal	 purchase	 agreement	 is	
considered	variable,	subject	to	changes	in	the	total	gold	ounces	to	be	delivered.	Changes	to	variable	consideration	are	
reflected	in	revenue	in	profit	or	loss.	The	additional	consideration	to	be	received	under	the	precious	metal	purchase	
agreement	is	considered	variable,	subject	to	changes	in	the	total	estimated	gold	ounces	to	be	delivered	and	gold	prices.

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

Changes	 to	 variable	 consideration	 are	 accounted	 for	 prospectively	 as	 a	 cumulative	 catch-up	 and	 are	 recorded	 in	
revenue	in	profit	or	loss.

(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.

(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	or	loss.	Interest	income	is	
recognized	as	it	accrues	in	profit	or	loss,	using	the	effective	interest	method.

Finance	expense	comprises	of	interest	expense	on	loans	and	borrowings,	accretion	expense	on	provisions,	leases	and	
deferred	revenue,	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.

Uncertainties	 over	 income	 tax	 treatments	 are	 evaluated	 on	 the	 basis	 of	 whether	 it	 is	 probable	 that	 they	 will	 be	
accepted	 upon	 examination	 by	 the	 relevant	 taxing	 authorities	 in	 Brazil.	 These	 uncertainties	 impact	 the	 amount	 of	
income	taxes	recognized.	If	it	is	determined	that	an	uncertain	income	tax	treatment	is	not	probable	of	being	accepted,	
the	effect	of	the	uncertain	income	tax	treatment	is	reflected	in	the	determination	of	income	taxes	based	the	most	likely	
amount	or,	if	there	are	a	wide	range	of	possible	outcomes,	the	expected	value.

(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.	Write-downs	of	inventories	to	net	
realizable	 value	 are	 included	 in	 the	 cost	 of	 sales	 in	 the	 period	 of	 the	 write-down.	 A	 write-down	 of	 inventories	 is	
reversed	in	a	subsequent	period	if	there	is	a	subsequent	increase	in	the	net	realizable	value	of	the	related	inventories.

Provisions	 for	 low	 turnover	 or	 obsolete	 supplies	 and	 consumables	 inventory	 are	 established	 by	 management	 as	
deemed	necessary	and	is	included	in	cost	of	sales.

(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	maintenance	service	costs	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.	 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	 an	 asset	 is	 available	 for	 use,	 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

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

the	underground	mines	are	capitalized	as	pre-production	stripping	or	development	costs	respectively	and	are	included	
within	mineral,	property,	plant	and	equipment.		

(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	 above	 average	 life	 of	 mine	 strip	 ratio	 (waste/ore)	 are	 capitalized	 to	 mineral	
properties	or	construction-in-progress	and	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

Lessor	of	life	of	mine	or	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	
tonnes	 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.

(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.	Once	the	legal	rights	or	license	is	obtained,	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).

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

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

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.		

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	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	

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	and	cash	equivalents
Trade	receivables	related	to	provisional	priced	sales
Other	receivables
Deposits
Financial	Liabilities
Trade	payables
Loans	and	borrowings
Derivatives

Cash	and	cash	equivalents	and	deposits

Measurement	Category

Amortized	Cost
Fair	value	through	profit	or	loss
Amortized	Cost
Amortized	Cost

Amortized	Cost
Amortized	Cost
Fair	value	through	profit	or	loss

Cash	is	comprised	of	cash	on	hand	and	demand	deposits.		Cash	equivalents	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.	

(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	
five	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,	 2021.	 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	 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	included	in	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	 equity	 settled	 share-based	 payment	 awards	 granted	 to	 employees	 and	 consultants,	
including	directors	and	officers,	is	recognized	as	share-based	compensation,	with	a	corresponding	increase	in	equity,	
over	 the	 period	 that	 the	 optionee	 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.	
Performance	 share	 units	 and	 deferred	 share	 units	 are	 liability	 awards	 settled	 in	 cash	 and	 measured	 at	 the	 quoted	
market	 price	 at	 the	 grant	 date	 with	 the	 corresponding	 expense	 recognized	 over	 the	 period	 that	 the	 employees	
unconditionally	become	entitled	to	the	awards.	The	corresponding	liability	is	adjusted	for	changes	in	fair	value	at	each	
subsequent	reporting	date	until	the	awards	are	settled.

(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.

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	per	Share

Basic	income	per	share	is	calculated	by	dividing	the	net	income	attributable	to	common	shareholders	of	the	Company	
by	the	weighted	average	number	of	common	shares	outstanding	during	the	period.		Diluted	income	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,	share	units	and	warrants.		The	dilutive	effect	of	share

options	 and	 warrants	 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	equity-settled	share	units	(as	defined	herein,	see	note	14(d)),	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	net	income	attributable	to	common	shareholders	
is	adjusted	to	eliminate	related	interest	costs	of	dilutive	securities	recognized	in	net	income	for	the	period.

(o) Business	combinations

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	 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.

4.

Segment	Disclosure

Operating	 segments	 are	 determined	 by	 the	 way	 information	 is	 reported	 and	 used	 by	 the	 Company's	 Chief	 Operating	
Decision	Maker	("CODM")	to	review	operating	performance.	The	Company’s	reporting	segments	include	its	two	operating	
mines	in	Brazil,	MCSA	and	NX	Gold,	and	its	corporate	head	office	in	Canada.	The	Company	monitors	the	operating	results	of	
its	 operating	 segments	 independently	 for	 the	 purpose	 of	 making	 decisions	 about	 resource	 allocation	 and	 performance	
assessment.		

Significant	information	relating	to	the	Company's	reportable	segments	is	summarized	in	the	tables	below:

the	tax	treatment	applicable	to	depletion	charges.	This	recovery	during	2020	was	recognized	as	a	result	of	a	study	conducted	to	revisit	certain	tax	
positions,	 which	 concluded	 that	 it	 is	 probable	 that	 additional	 tax	 credits	 are	 available	 to	 be	 used	 to	 offset	 a	 variety	 of	 taxes.	No	 additional	 value	
added	tax	recoveries	were	recognized	in	2021.

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

(a)	 Senior	Credit	Facility

At	December	31,	2020,	the	Company	had	a	$150.0	million	credit	facility	from	a	syndicate	of	Canadian	financial	institutions.	
The	 credit	 facility	 was	 comprised	 of	 $75.0	 million	 in	 senior	 secured	 non-revolving	 credit	 facility	 (“Term	 Facility”)	 and	 a	
$75.0	million	senior	secured	revolving	credit	facility	(“Revolving	Credit	Facility”)	(collectively,	the	"Old	Facilities).	The	Term	
Facility	was	to	mature	on	March	31,	2024	and	required	principal	repayments	on	a	quarterly	basis	commencing	on	March	31,	
2022,	while	the	Revolving	Credit	Facility	was	payable	in	full	at	maturity	on	March	31,	2024.	The	Old	Facilities	bore	interest	
on	a	sliding	scale	at	a	rate	of	LIBOR	plus	2.50%	to	4.25%,	depending	on	the	Company’s	consolidated	leverage	ratio.

During	the	year	ended	December	31,	2021,	the	Old	Facilities	were	amended	and	combined	into	a	new	$150.0	million	senior	
secured	revolving	credit	facility	(“New	Revolving	Credit	Facility”)	with	maturity	date	of	March	31,	2025.	The	New	Revolving	
Credit	 Facility	 bears	 interest	 on	 a	 sliding	 scale	 at	 a	 rate	 of	 LIBOR	 plus	 2.25%	 to	 4.25%	 depending	 on	 the	 Company’s	
consolidated	leverage	ratio.	Commitment	fees	for	any	undrawn	portion	of	the	New	Revolving	Credit	Facility	are	on	a	sliding	
scale	between	0.56%	to	1.06%.	

During	the	year	ended	December	31,	2021,	the	Company	also	paid	down	the	New	Revolving	Credit	Facility	by	$100.0	million	
with	$50.0	million	remaining	outstanding	as	at	December	31,	2021.	The	Company	has	an	interest	rate	swap	arrangement	
whereby	 floating	 interest	 on	 $50.0	 million	 (2020	 -	 $50.0	 million)	 of	 the	 New	 Revolving	 Credit	 Facility	 was	 swapped	 for	 a	
fixed	interest	rate	of	1.68%	(2020	-	2.69%).	The	interest	rate	swap	arrangement	is	in	effect	until	March	31,	2025.		

Subsequent	to	year	end,	pursuant	to	completion	of	an	offering	of	$400.0	million	in	Senior	Notes	(note	26),	the	Company	
repaid	 the	 outstanding	 $50.0	 million	 balance	 of	 the	 New	 Revolving	 Credit	 Facility	 and	 settled	 the	 interest	 rate	 swap	
arrangement	 for	 nominal	 consideration.	 The	 New	 Revolving	 Credit	 Facility	 was	 further	 amended	 to	 reduce	 its	 limit	 from	
$150.0	million	to	$75.0	million,	with	an	accordion	option	to	increase	to	$100.0	million	at	the	election	of	the	Company.

The	New	Revolving	Credit	Facility	is	secured	by	pledges	of	shares	of	MCSA,	NX	Gold	and	Ero	Gold.	The	Company	is	required	
to	comply	with	certain	financial	covenants.	As	December	31,	2021,	the	Company	is	in	compliance	with	these	covenants.

(b)	 Bank	Loan	and	Equipment	Finance	Loans

The	MCSA	bank	loan	was	recognized	at	fair	value	when	the	Company	acquired	MCSA	and	has	subsequently	been	measured	
at	amortized	cost,	net	of	settlements.	Interest	is	being	recognized	using	the	effective	interest	rate	method	at	an	interest	
rate	of	11.50%.	

MCSA	 is	 subject	 to	 certain	 financial	 covenants	 which	 the	 Company	 is	 in	 compliance	 with	 at	 December	 31,	 2021.	 The	
equipment	finance	loans	are	secured	by	the	corresponding	equipment	relating	to	them	and	a	guarantee	by	the	Company.

At	December	31,	2020,		MCSA	had	entered	into	an	equipment	finance	loan	with	Plural	Bank	for	BRL	$12.0	million	for	a	term	
of	24	months	and	at	an	interest	rate	of	7%	+	CDI	per	annum.	MCSA	had	also	entered	into	an	interest	rate	swap	transaction	
and	a	foreign	exchange	swap	transaction	with	Plural	Bank	related	to	this	loan	whereby	the	floating	interest	of	7%	+	CDI	on	a	
notional	amount	of	BRL	$12.0	million	was	swapped	for	a	fixed	interest	rate	of	9.90%,	and	a	notional	principal	amount	of	BRL	
$12.0	million	was	swapped	for	the	USD	currency	at	a	foreign	exchange	rate	of	3.9500.	This	loan	was	repaid	during	the	year	
ended	December	31,	2021	and	the	interest	rate	and	foreign	currency	swap	contracts	terminated.

As	at	December	31,	2020,	the	Company’s	subsidiaries,	MCSA	and	NX	Gold,	had	entered	into	various	lines	of	credit	for	a	total	
amount	of	BRL	$154.6	million	of	which	BRL	$21.8	million	($4.2	million)	was	outstanding.	These	credit	facilities	bore	interest	
at	 various	 rates	 ranging	 from	 9.60%	 to	 24.34%.	 During	 the	 year	 ended	 December	 31,	 2021,	 the	 Company’s	 subsidiaries,	
MCSA	and	NX	Gold,	terminated	all	remaining	available	credit	facilities.

During	the	year	ended	December	31,	2020,	the	Company	repaid	BRL	$162.2	million	on	various	lines	of	credit	entered	into	in

(1)	Includes	$50.0	million	of	the	New	Revolving	Credit	Facility	repaid	in	February	2022	which	does	not	mature	until	March	31,	2025.

11.	Deferred	Revenue

In	August	2021,	the	Company	completed	the	closing	of	a	precious	metals	purchase	agreement	(the	“NX	Gold	PMPA”)	with	
Royal	 Gold	 in	 relation	 to	 gold	 production	 from	 the	 NX	 Gold	 mine.	 The	 Company	 received	 upfront	 cash	 consideration	 of	
$100.0	million	for	the	purchase	of	25%	of	an	equivalent	amount	of	gold	to	be	produced	from	the	NX	Gold	mine	until	93,000	
ounces	of	gold	have	been	delivered	and	thereafter	decreasing	to	10%	of	gold	produced	over	the	remaining	life	of	the	mine.	
Royal	Gold	will	make	ongoing	payments	equal	to	20%	of	the	then	prevailing	spot	gold	price	for	each	ounce	of	gold	delivered	
until	49,000	ounces	of	gold	have	been	received	and	40%	of	the	prevailing	spot	gold	price	for	each	ounce	of	gold	delivered	
thereafter.	Additional	payment	obligations	of	Royal	Gold	include:

i.

Up	to	US$5	million,	available	through	the	end	of	2024,	payable	based	upon	the	number	of	ounces	of	gold	added	to	
the	Measured	and	Indicated	mineral	resource	categories	as	compared	to	the	mineral	resources	as	of	the	effective	
date	of	the	NX	Gold	Transaction	at	a	rate	of	US$20	per	ounce;	

ii. Up	to	US$5	million,	available	from	2022	through	the	end	of	2024,	payable	based	upon	completion	of	planned	meters	

of	drilling	within	the	exploration	concessions	of	the	NX	Gold	mine	at	a	rate	of	US$100	per	meter;	and,

iii. US$5	per	ounce	of	gold	delivered	under	the	NX	Gold	Transaction	payable	to	the	Company	as	contribution	towards	

ongoing	environmental,	social	and	governance	initiatives	within	the	area	of	influence	of	the	mine.

The	contract	will	be	settled	by	the	Company	delivering	gold	to	Royal	Gold.	The	$100.0	million	upfront	proceeds	from	Royal	
Gold	has	been	recognized	as	deferred	revenue	and	the	Company	recognizes	amounts	in	revenue	as	gold	is	delivered.	Each	
period,	 management	 estimates	 the	 cumulative	 amount	 of	 the	 deferred	 revenue	 obligation	 that	 has	 been	 satisfied	 and,	
therefore,	recognized	as	revenue.	Key	inputs	into	the	estimate	at	closing	of	the	transaction	included	an	estimated	long-term	
gold	price	of	$1,750	per	ounce	and	a	life	of	mine	production	schedule	for	the	NX	Gold	mine	that	includes	mineral	reserves	
and	a	portion	of	the	mineral	resources.

During	 the	 year	 ended	 December	 31,	 2021,	 the	 Company	 delivered	 5,173	 ounces	 of	 gold	 to	 Royal	 Gold	 for	 average	
consideration	of	$353	per	ounce	and	recognized	$7.3	million	in	amortization	of	deferred	revenue.	As	at	December	31,	2021,

the	 aggregate	 carrying	 value	 of	 deferred	 revenue	 was	 $94.2	 million,	 of	 which	 $10.5	 million	 was	 classified	 as	 current	 and	
$83.7	million	was	classified	as	non-current.

As	part	of	the	NX	Gold	PMPA,	the	Company	incurred	$1.2	million	in	transaction	fees	during	the	year	ended	December	31,	
2021.	In	addition,	the	Company	pledged	its	equity	interest	in	Ero	Gold	and	NX	Gold	to	Royal	Gold	as	collateral	and	provided	
unsecured	limited	recourse	guarantees	from	Ero	and	NX	Gold.

Provision	for	rehabilitation	and	closure	costs	is	measured	using	management’s	assumptions	and	estimates	for	future	cash	
outflows	 in	 relation	 to	 mine	 closure	 and	 rehabilitation	 activities	 based	 on	 known	 disturbances	 as	 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	8.23%	–	8.81%	(2020	–	5.75%	-	7.37%)	and	an	inflation	factor	in	
the	 range	 of	 3.00%	 -	 5.03%	 (2020	 –	 3.25%	 -	 3.50%)	 in	 preparing	 the	 Company’s	 provision	 for	 rehabilitation	 and	 closure	
costs.	Although	the	ultimate	amount	to	be	incurred	is	uncertain,	based	on	development,	legal	requirements	and	estimated	
costs	as	at	December	31,	2021,	the	undiscounted	inflation-adjusted	liability	for	provision	for	rehabilitation	and	closure	costs	
is	estimated	to	be	approximately	$65.5	million	(2020	-	$37.0	million),	of	which	$59.4	million	(2020	-	$31.4	million)	relates	to	
MCSA	 and	 $6.1	 million	 (2020	 -	 $5.6	 million)	 relates	 to	 NX	 Gold.	 The	 cash	 expenditures	 are	 expected	 to	 commence	 upon	
projected	closure	and	occur	over	a	period	of	time,	which	for	MCSA	is	in	a	range	from	2026	to	2046	and	for	NX	Gold	is	2027

For	 the	 year	 ended	 December	 31,	 2021,	 the	 Company	 recorded	 share-based	 compensation	 of	 $2.9	 million	 (year	 ended	
December	31,	2020	-	$3.9	million)	with	respect	to	its	outstanding	stock	options.

(b)		 Performance	Share	Unit	Plan

The	Company	has	a	performance	share	unit	("PSU")	plan	pursuant	to	which	the	Compensation	Committee	may	grant	PSUs	
to	 any	 director,	 officer,	 employee,	 or	 consultant	 of	 the	 Company	 or	 its	 subsidiaries.	 At	 the	 time	 of	 grant	 of	 PSUs,	 the	
Compensation	Committee,	may	establish	performance	conditions	for	the	vesting	of	the	PSUs.	The	performance	conditions	
may	 be	 graduated	 such	 that	 different	 percentages	 (which	 may	 be	 greater	 or	 lower	 than	 100%)	 of	 the	 PSUs	 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	common	shares;	(ii)	the	return	to	holders	of	common	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	 Compensation	 Committee	 may	 in	 its	 sole	 discretion	 determine	 with	
respect	to	vesting	or	the	acceleration	of	vesting;	and	(vi)	the	vesting	date	of	the	PSUs.	The	Compensation	Committee	may,	
in	its	discretion,	subsequent	to	 the	grant	 of	 a	PSU,	 waive	any	such	performance	 condition	or	 determine	that	 it	has	been	
satisfied	subject	to	applicable	law,	as	well	as	determine	the	settlement	of	PSUs	in	shares	or	in	cash.	Each	PSU	entitles	the	
holder	 thereof	 to	 receive	 one	 common	 share,	 or	 its	 equivalent	 cash	 value,	 on	 the	 redemption	 date	 selected	 by	 the	
Compensation	Committee.

The	continuity	of	PSUs	issued	and	outstanding	is	as	follows:

Outstanding	balance,	beginning	of	year

Issued	
Settled
Cancelled

Outstanding	balance,	end	of	year

Year	ended	December	31,

These	PSUs	will	vest	three	years	from	the	date	of	grant	by	the	Compensation	Committee	and	the	number	of	PSUs	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	PSU	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	Compensation	Committee	in	its	sole	
discretion.	Prior	to	December	2021,	the	Company	had	intended	to	settle	its	PSUs	using	common	shares	and,	accordingly,	
the	PSUs	were	classified	as	equity	settled	instruments.	In	December	2021,	the	Company	elected	to	settle	its	PSUs	in	cash	
and,	 therefore,	 $9.4	 million	 of	 PSUs	 were	 reclassified	 from	 contributed	 surplus	 to	 liabilities.	 On	 reclassification,	 the	
Company	recognized	the	liability	at	its	fair	value	and	recognized	a	reduction	in	shared-based	compensation	of	$1.2	million.

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

For	PSUs	with	non-market	performance	conditions,	the	fair	value	of	the	share	units	granted	was	initially	recognized	at	the	
fair	value	using	the	share	price	at	the	date	of	grant,	and	subsequently	remeasured	at	fair	value	on	each	balance	sheet	date.	
For	PSUs	with	market	performance	conditions,	the	fair	value	was	determined	using	a	Geometric	Brownian	Motion	model.		

During	the	year	ended	December	31,	2021,	the	Company	recorded	share-based	compensation	of	$4.1	million	(year	ended	
December	31,	2020	-	$3.9	million)	with	respect	to	the	PSUs.	As	at	December	31,	2021,	the	fair	value	of	the	PSU	liability	was	
$5.8	million	(December	31,	2020	-	$nil),	of	which	$3.3	million	(December	31,	2020	-	nil)	has	been	recognized	in	accounts	
payable	 and	 accrued	 liabilities	 and	 $2.5	 million	 (December	 31,	 2020	 -	 $nil)	 has	 been	 recognized	 in	 other	 non-current	
liabilities.	

(c)		 Deferred	Share	Unit	Plan

The	Deferred	Share	Unit	("DSU")	plan	was	established	by	the	Board	as	a	component	of	compensation	for	the	Company's	
independent	directors.	Only	independent	directors	are	eligible	to	participate	and	to	receive	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.	

During	 the	 year	 ended	 December	 31,	 2021,	 51,855	 DSUs	 (year	 ended	 December	 31,	 2020	 -	 79,230)	 were	 issued	 to	
independent	directors.	

As	at	December	31,	2021,	the	fair	value	of	the	DSU	liability	was	$2.0	million	(December	31,	2020	-	$1.3	million)	which	has	
been	 recognized	 in	 accounts	 payable	 and	 accrued	 liabilities,	 with	 $0.7	 million	 recognized	 in	 share-based	 compensation	
expense	for	the	year	ended	December	31,	2021	(year	ended	December	31,	2020	-	$1.3	million).	

(d)	Restricted	Share	Unit	Plan	

The	 Company	 has	 a	 restricted	 share	 unit	 ("RSU")	 plan	 pursuant	 to	 which	 the	 Compensation	 Committee	 may	 grant	 share	
units	 to	 any	 officer,	 employee,	 or	 consultant	 of	 the	 Company	 or	 its	 subsidiaries.	 RSUs	 issued	 under	 the	 plan	 entitles	 the	
holder	 thereof	 to	 receive	 one	 common	 share,	 without	 payment	 of	 additional	 consideration,	 on	 the	 redemption	 date	
selected	by	the	Compensation	Committee	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.	RSUs	granted	will	vest	in	three	
equal	 installments	 on	 each	 anniversary	 date	 from	 the	 date	 of	 grant.	 The	 fair	 value	 of	 these	 restricted	 share	 units	 is	
determined	on	the	date	of	grant	using	the	market	price	of	the	Company’s	shares.

During	 the	 year	 ended	 December	 31,	 2021,	 171,106	 share	 units	 (year	 ended	 December	 31,	 2020	 -	 nil)	 were	 issued	 and	
outstanding.		

(e)		 Warrants

During	the	year	ended	December	31,	2021,	all	of	the	remaining	1,599,996	warrants	were	exercised	for	gross	proceeds	of	
$1.9	million	(year	ended	December	31,	2020	-	1,266,666	warrants	for	gross	proceeds	of	$1.5	million).

22. 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.	Judgments	are	required	in	the	interpretation	of	the	market	data	to	produce	
the	most	appropriate	fair	value	estimates.	The	use	of	different	market	information	and/or	evaluation	methodologies	may	
have	a	material	effect	on	the	fair	value	amounts.

As	at	December	31,	2021,	derivatives	were	measured	at	fair	value	based	on	Level	2	inputs.		

The	 carrying	 values	 of	 cash	 and	 cash	 equivalents,	 short-term	 investments,	 accounts	 receivable,	 deposits,	 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.	At	December	31,	2021,	the	carrying	value	of	loans	and	borrowings	is	$59.3	million	while	the	face	
value	 is	 approximately	 $61.2	 million.	 The	 contractual	 interest	 rates	 on	 these	 loans	 and	 borrowings	 are	 a	 close	
approximation	of	market	rates	of	interest	at	December	31,	2021	(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,	2021	and	December	31,	2020:

The	Company	invests	cash	and	cash	equivalents	and	short-term	investments	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	five	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,	2021	and	2020	nor	recognized	a	provision	for	credit	losses.				

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.

amounts	and	maturity	information	is	disclosed	below	under	foreign	exchange	currency	risk	and	interest	rate	risk.

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.

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

(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,	 2021	 relates	 to	 $7.8	 million	 (December	 31,	
2020	–	$7.4	million)	in	loans	and	borrowings	of	MCSA	denominated	in	US	dollars	and	Euros.	In	addition,	the	Company	is	also	
exposed	 to	 foreign	 exchange	 currency	 risk	 at	 December	 31,	 2021	 on	 $63.8	 million	 due	 to	 an	 intercompany	 loan	 balance	
(December	 31,	 2020	 -	 $83.1	 million)	 which	 has	 contractual	 repayment	 terms.	 Strengthening	 (weakening)	 in	 the	 Brazilian	
Real	against	the	US	dollar	at	December	31,	2021	by	10%	and	20%,	would	have	increased	(decreased)	pre-tax	net	income	by	
$7.0	 million	 and	 $13.9	 million,	 respectively	 (2020	 –	 $8.9	 million	 and	 $17.7	 million).	 Strengthening	 (weakening)	 in	 the	
Brazilian	 Real	 against	 the	 Euro	 at	 December	 31,	 2021	 by	 10%	 and	 20%,	 would	 have	 increased	 (decreased)	 pre-tax	 net	
income	by	$0.2	million	and	$0.4	million,	respectively	(2020	–	$0.2	million	and	$0.4	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,	2021,	the	Company	has	entered	into	foreign	exchange	collar	contracts	at	zero	cost	for	notional	amounts	of	
$179.5	million	(December	31,	2020	-	notional	amount	of	$285.7	million)	with	an	average	floor	rate	of	4.24	BRL	to	US	Dollar	
and	 an	 average	 cap	 rate	 of	 4.76	 BRL	 to	 US	 Dollar.	 The	 maturity	 dates	 of	 these	 contracts	 are	 from	 January	 3,	 2022	 to	
December	28,	2022	and	are	financially	settled	on	a	net	basis.	The	fair	value	of	these	contracts	at	December	31,	2021	was	a	
liability	of	$28.7	million,	(December	31,	2020	-	$34.5	million)	which	is	included	in	Derivatives	in	the	statement	of	financial	
position.	The	fair	value	of	these	forward	contracts	as	at	December	31,	2021	was	determined	using	an	option	pricing	model	
with	 the	 following	 assumptions:	 discount	 rate	 of	 2.74%	 -	 2.80%,	 foreign	 exchange	 rate	 of	 approximately	 5.59—6.17,	 and	
volatility	of	15.69%	-	17.92%.	

The	change	in	fair	value	of	foreign	exchange	collar	contracts	was	a	gain	of	$3.9	million	for	the	year	ended	December	31,	
2021	(a	loss	of	$34.5	million	for	the	year	ended	December	31,	2020)	and	has	been	recognized	in	foreign	exchange	loss.	In	
addition,	during	the	year	ended	December	31,	2021,	the	Company	recognized	a	realized	loss	of	$22.2	million	(realized	loss	
of	 $20.8	 million	 for	 the	 year	 ended	 December	 31,	 2020)	 related	 to	 the	 settlement	 of	 foreign	 currency	 forward	 collar	
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	 New	 Revolving	 Credit	 Facility	 of	 $50.0	 million	 and	
Brazilian	Real	denominated	bank	loans	of	$3.5	million.	Based	on	the	Company’s	net	exposure	at	December	31,	2021,	a	1%	
change	in	the	variable	rates	would	have	an	impact	of	$0.5	million	on	pre-tax	annual	net	income,	without	consideration	of	
the	effects	of	the	interest	rate	swap	contract	below.

In	 order	 to	 mitigate	 the	 above	 volatility	 due	 to	 variable	 rates	 on	 loans,	 the	 Company	 entered	 into	 an	 interest	 rate	 swap	
contract	to	manage	interest	rate	risk	(see	note	10(a)).	At	December	31,	2021,	the	floating	interest	on	a	notional	amount	of	
$50.0	million	was	swapped	for	a	fixed	interest	rate	of	1.68%.	This	interest	rate	swap	transaction	is	in	effect	until	March	31,	
2025,	with	settlements	made	on	a	monthly	basis.	The	fair	value	of	this	contract	at	December	31,	2021	was	a	liability	of	$1.0	
million	(December	31,	2020	-	$2.5	million)	and	was	included	in	Derivatives	in	the	statement	of	financial	position.	

For	 the	 year	 ended	 December	 31,	 2021,	 the	 Company	 recognized	 a	 realized	 loss	 of	 $0.8	 million	 (a	 realized	 loss	 of	
$1.6	million	for	the	year	ended	December	31,	2020)	and	an	unrealized	gain	of	$1.3	million	(an	unrealized	loss	of	$1.1	million	
for	the	year	ended	December	31,	2020),	respectively,	in	relation	to	its	interest	rate	swap	derivatives.

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

(iii)	Price	risk	

The	 Company	 may	 use	 derivatives,	 including	 forward	 contracts,	 collars	 and	 swap	 contracts,	 to	 manage	 commodity	 price	
risks.	 At	 December	 31,	 2021,	 the	 Company	 has	 provisionally	 priced	 sales	 that	 are	 exposed	 to	 commodity	 price	 changes	
(note	15).	Based	on	the	Company’s	net	exposure	at	December	31,	2021,	a	10%	change	in	the	price	of	copper	would	have	an	
impact	of	$0.2	million	on	pre-tax	net	income.

23. 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.	

The	Company's	capital	consists	of	items	included	in	shareholders’	equity,	debt	facilities	net	of	cash	and	cash	equivalents.

Management	 reviews	 the	 capital	 structure	 on	 a	 regular	 basis	 to	 ensure	 that	 the	 above-noted	 objectives	 are	 met.	 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.

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.

25. Contingencies

Due	to	the	nature	of	the	Company’s	operations,	various	legal,	tax,	environmental	and	regulatory	matters	are	outstanding	
from	 time	 to	 time.	 By	 their	 nature,	 contingencies	 will	 only	 be	 resolved	 when	 one	 or	 more	 future	 events	 occur	 or	 fail	 to

occur.	 The	 assessment	 of	 contingencies	 inherently	 involves	 the	 exercise	 of	 significant	 judgement	 and	 estimates	 of	 the	
outcome	 of	 future	 events.	 While	 the	 outcomes	 of	 these	 matters	 are	 uncertain,	 based	 upon	 the	 information	 currently	
available,	 the	 Company	 does	 not	 believe	 that	 these	 matters	 in	 aggregate	 will	 have	 a	 material	 adverse	 effect	 on	 its	
consolidated	 financial	 statements.	 In	 the	 event	 that	 management’s	 estimate	 of	 the	 future	 resolution	 of	 these	 matters	
changes,	the	Company	will	recognize	the	effect	of	these	changes	in	its	consolidated	financial	statements	in	the	period	in	
which	such	changes	occur.	

As	of	December	31,	2021,	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	$9.5	million	is	included	in	the	table	above.		

(b)	Tax

There	are	122	tax	claims	(2020	–	121	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.		

(c)	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.

26.		Subsequent	events

In	February	2022,	the	Company	closed	an	offering	of	$400	million	aggregate	principal	amount	of	Senior	Notes	due	2030	(the	
“Notes”).	Interest	on	the	Notes	accrues	at	an	annual	rate	of	6.50%,	payable	semi-annually	in	arrears.	The	Notes	mature	on	
February	15,	2030.		MCSA	is	currently	the	only	guarantor	of	the	Notes	on	a	senior	unsecured	basis.	The	Notes	are	direct,	
senior	 obligations	 of	 the	 Company	 and	 MCSA,	 and	 are	 not	 secured	 by	 any	 mortgage,	 pledge	 or	 charge.	 Estimated	
transaction	costs	related	to	the	offering	of	the	Notes	was	$8.5	million.	

Pursuant	 to	 closing	 of	 the	 Notes	 offering,	 the	 Company	 repaid	 the	 outstanding	 balance	 under	 its	 New	 Revolving	 Credit	
Facility	of	approximately	$50	million	and	reduced	the	size	of	its	New	Revolving	Senior	Credit	Facility	from	$150	million	to	
$75	million,	with	an	accordion	option	to	increase	to	$100.0	million	at	the	election	of	the	Company.

The Company’s forward-looking statements are based on the assumptions, beliefs, expectations and opinions of management on the date the statements 
are made, many of which may be difficult to predict and beyond the Company’s control. In connection with the forward-looking statements contained in this 
Annual Report, the Company has made certain assumptions about, among other things: continued effectiveness of the measures taken by the Company 
to mitigate the possible impact of COVID-19 on its workforce and operations; 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, gold 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 MCSA Mining Complex, the NX Gold Property and the Boa Esperança Property being as described in the MCSA Mining Complex 
Technical Report, the NX Gold Technical Report and the Boa Esperança Technical Report, respectively; production costs; the accuracy of budgeted exploration, 
development  and  construction  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; work force continuing to remain 
healthy in the face of prevailing epidemics, pandemics or other health risks (including COVID-19), 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. Although the Company believes that the assumptions inherent in forward-looking statements are 
reasonable as of the date of this Annual Report, these assumptions are subject to significant business, social, economic, political, regulatory, competitive 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 statements. The Company cautions that the foregoing list of assumptions is 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 statements contained in this Annual Report.

Forward-looking  statements  contained  herein  are  made  as  of  the  date  of  this  Annual  Report  and  the  Company  disclaims  any  obligation  to  update  or 
revise any forward-looking statement, 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 in 
this ANNUAL REPORT 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”). 
NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and 
technical information concerning mineral projects. NI 43-101 differs significantly from the disclosure requirements of the Securities and Exchange Commission 
(the “SEC”) generally applicable to U.S. companies. For example, the terms “mineral reserve”, “proven mineral reserve”, “probable mineral reserve”, “mineral 
resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in NI 43-101. These definitions differ from 
the definitions in the disclosure requirements promulgated by the SEC. Accordingly, information contained in this ANNUAL REPORT may not be comparable 
to similar information made public by U.S. companies reporting pursuant to SEC disclosure requirements. 

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.
