Contrary to all the naysayers throughout the long years, the Company has established a world class, environmentally friendly mining operation, developed and operated in the People’s Republic of China (“PRC” or “China”), on a self-generating cash flow basis, without seeking continual capital from shareholders or • Lead in concentrate produced was up 64.5% to 1,546 tonnes. These results are all the more impressive in light of the fact that no ore is yet being delivered from Zone II, which remains under full speed development.

Grade control drilling continues unabated and the South Ventilation Shaft has been sunk almost 250 metres. Ore extraction from Zone II remains on schedule for the 1st Quarter of 2025. incurring debt. Put simply, in the words of Helen Keller, Drilling continues in both Zones II and III with a record “While they were saying it couldn’t be done, it was done.” 7 diamond drill rigs in continual operation.

The Company and its subsidiaries (together the “Group”) recorded; of operating rigs is yet another record for the Caijiaying Mine. With the volume and quality of the drilling information being produced, it is our expectation that a new JORC resource will be announced in 2024. With continuing operational and financial success, it is easy to become complacent and fail to deal with non-financial issues which impact the future viability of the Company. • Revenues up 54.7% at $146,023,000; As such, the Company strives to be a fully responsible • Gross profit up 35.5% at $51,842,000; • EBIT up 47.3% at $51,863,000; • Operating profit up 52.5% at $23,837,000; • Profit before tax up 60.3% at $24,486,000; corporate citizen to all our relevant stakeholders, including our shareholders, employees, contractors, the people of China and the global environment.

I know of no other active mine or operations that can claim to have fully committed to the switch to 100% renewable energy and already be generating a third of its energy from its solar farm. 4 Griffin MininG LiMitedInevitably the question then arises how to deal with the I should mention that this year marks the 30th anniversary excess cash being generated by operations. It was decided of Hebei Hua Ao Mining Industry Co Ltd (“Hebei Hua by the directors of the Company not only to continue with Ao”), the foreign joint venture stock company formed the on-market share buy-back scheme operated by the in 1994 to hold the interest in the Caijiaying Mine, the Company’s Nominated Advisor, Panmure Gordon, but majority interest of which was acquired by Griffin almost to also undertake an offer for larger blocks of stock held 4 years later in 1997/8.

As such, well over 10 million shares absolute hope that at these celebrations there will also be were acquired and then cancelled by the 26 February 2024 an announcement of Hebei Hua Ao converting its legal at a substantially lower share price than currently quoted. status to a limited liability company, as mandated in the It is expected both methods of buying back the Company’s PRC Foreign Investment Law (Article 42), bringing all the stock will continue in 2024, reducing the Company’s benefits of that legal structure to the parties involved. shares outstanding and improving the Company’s earnings per share. To this end, and although I rarely comment on the Company’s share price, it has been pleasing to see the market finally seemingly begin to understand the inherent value of the Company and even perhaps the parlous state of the world mining environment. All that remains for me to conclude is that the old adage remains as true today as when it was written so long ago by Tacitus and re-imagined by John F Kennedy, “Success has many fathers, but failure is an orphan.” An operation of the size, complexity and in the location of the Caijiaying Mine, has depended on, and will continue to depend on, the In that vein, I believe it appropriate to mention the very intelligence, expertise, dedication, discipline and sacrifice recent indicative proposal announcement by BHP in of a large number of individuals. I can’t and won’t name relation to Anglo-American, an attempt by BHP to acquire them as to do so would inevitably exclude someone who scarce copper assets. Although this may be a surprise to has deserved to be in that pantheon of champions. Suffice the market, it is a logical progression of the failure of the it to say I regularly refer to some current success which capital markets to support the mining industry, and in rests either on our founding directors’ feet, our current particular the junior miners, who overwhelmingly discover operational staff and/or our relatively new directors. All the orebodies needed to supply the world with the raw have played or continue to play their vital part and we owe products needed for human existence. We have just begun them our sincerest thanks. It needs to be understood by all to feel the effects of having rare resources and its expression involved that what they all do is beyond the responsibilities in rising commodity prices. As Mark Burton at Bloomberg of ordinary corporate employment and it deserves our wrote recently, “A successful takeover would make BHP acknowledgment. the biggest copper producer with about 10% of the market, but it won’t make any difference toward meeting the world’s supply needs. Production from existing mines is set to fall sharply in the coming years, and miners would need to spend more than $150 billion between 2025 and 2032 in order to fulfill the industry’s supply needs, according to CRU Group. One key challenge is that new mines take years and often decades to build, ‘There is a clear and compelling need for additional mine capacity to be brought online,’ said William Tankard, principal analyst for base metals at CRU. ‘The gauntlet is being laid down at the feet of the miners, and it’s going to be exceptionally challenging to deliver.” Lastly, and always most importantly, thank you to you, the shareholders and owners of the Company. Everyone can “talk the talk” but few can “walk the walk.” It is your capital, patience and continued support which allows the Company to have the stability and confidence to continue to move forward at an ever quicker pace. We will continue to honour the commitment you have all made by moving heaven and earth to give you the returns you so richly deserve.

Caijiaying INTRODUCTION DEVELOPMENT The Caijiaying Mine is an operating zinc, gold, silver, Hebei Hua Ao is a contractual co-operative joint venture and lead mine, together with processing plant, camp and company established in 1994 under PRC law. Initially, supporting facilities, located approximately 250 kilometres Griffin held 60% of Hebei Hua Ao (through its wholly by road, north-west of Beijing in the Hebei Province of the owned subsidiary China Zinc), with the remaining 40% held PRC. The Caijiaying Mine is easily accessible by freeway by Yuanrun, the shareholders of which are the Zhangjiakou from Beijing. The site has significant water supplies, an on City People’s Government and the Third Geological site solar farm together with two 35,000 volt power lines Brigade of Hebei Province (the “Third Brigade”). connected to the electricity grid, full connectivity to fixed and mobile telecommunications systems and broadband access for internet services. It is 63 kilometres from Chongli, the closest station on the high speed train link with Beijing. The initial operating term of Hebei Hua Ao was 25 years and was due to expire in 2019. In light of the continuing increase in the resources base and production profile of the Caijiaying Mine, the Company, through China Zinc, purchased an additional 28.8% interest in Hebei Hua Ao There are a number of zones of mineralisation within the from Yuanrun in 2012. Griffin now holds an 88.8% equity tenements held by Hebei Hua Ao at the Caijiaying Mine interest in Hebei Hua Ao and Yuanrun retains an 11.2% including Zone III, which is currently being mined, and residual interest. This interest is compensated via a service Zone II, being developed for production in 2025. contract (for accounting purposes) for services rendered, Climatic conditions are relatively mild with warm summers and cold winters, enabling the Caijiaying Mine to operate throughout the year. resulting in Hebei Hua Ao being in the nature of a wholly owned subsidiary of the Company. In addition, and as part of this purchase agreement, the term of the Hebei Hua Ao joint venture was extended to October 2037. 8 Griffin MininG LiMitedGeographic location of the Caijiaying Mine, People’s Republic of China 9 RepoRt and accounts 2023Caijiaying (continued) On 1 January 2020 a new PRC Foreign Investment Law development efforts focusing on accessing the Zone II was enabled which repealed the Sino Foreign Joint Venture resource while maintaining mine production at Zone III. Law. Pursuant to Article 42, all Joint Ventures established under the previous law must be converted into limited liability companies by 1 January 2025 with a new business licence. This will require, inter alia, the adoption of new Articles of Association which will have significant benefits for the Company including the inevitable exclusion of the termination of the current joint venture in 2037 as a limited liability company, and a new business licence. In January 2004, a second contractual joint venture company, Hebei Anglo, was formed to hold the mineral rights to the area surrounding the original Hebei Hua Ao licence area and any other areas of interest in Hebei Province. Griffin, through its wholly owned UK subsidiary Panda Resources Limited (“Panda”), has a 90% interest in Hebei Anglo whilst Yuanrun holds 10%. As Griffin investigates other areas of interest and projects in China, Hebei Anglo may be used to invest in any such projects. The Caijiaying Mine was commissioned on time and on budget in 2005. Numerous upgrades to the Caijiaying Mine have taken place since commissioning leading to the current mill throughput capacity of 1.5 million tonnes of ore per annum. Mining rates solely from Zone III have now reached the equivalent of 1.5 million tonnes of ore per annum. The development of Zone II at the Caijiaying Mine, now being undertaken, will enable current and possibly higher production rates in the future. To date Griffin has invested some $400 million on acquiring its interest in the Caijiaying Mine and in the development and construction of the workings and processing facilities, financed mainly from internally generated funds. Mineral resources at the Caijiaying Mine are organized into four zones. From south to north, the main line of lodes comprise mineral resources from Zones II, III and VIII, while Zone V sits just 1km west of Zone II. Underground mine production began at Zone III in 2005, consistently delivering robust production levels and achieving record production in 2023. The Global Mineral Resource that encompasses the entire area totals, 83.1 million tonnes at 3.9% Zn, 0.6% Pb, 29.4g/t Ag and 0.4g/t Au resulting in total contained metal of approximately 3.24 million tonnes of Zn, 0.5 million tonnes of Pb, 78.4 million ounces of Ag and 1.13 million ounces of Au. This applies a zinc cut-off grade of 1% and is amended for mining depletion at Zone III as of 31 December 2023. In 2023, an extensive underground diamond drill program covering Zone II and III achieved a total amount drilled of 50,915 metres. The primary aim of this ongoing campaign is to reduce operational risks and enhance resource confidence during the transition to Zone II. Simultaneously, it seeks to uncover new opportunities in areas adjacent to the mined zones in Zone III and evaluate potential targets inferred to the east of the mine. Zone III The updated 2023 Mineral Resource Estimate at Zone III at a zinc cut-off grade of 1% using actual drilling as of July 2023 and amended for mining depletion up to 31 December 2023 totals 32.1 million tonnes at 4.6% Zn, 0.2% Pb, 24.9g/t Ag and 0.6g/t Au. This results in total metal of approximately 1.5 million tonnes of Zn, 0.08 With the grant of a new mining licence in December million tonnes of Pb, 25.7 million ounces of Ag and 0.6 2020 over the combined Zone II and Zone III areas, and million ounces of Au. consequent approval of a mine design for the new Zone II area, the development of Zone II is well underway. Production from Zone II is expected in 2025. This will allow sustained production of at least 1.5 million tonnes of ore per annum to be extracted from the Caijiaying Mine for the extent of its current resource base, if not longer. MINERAL RESOURCE ESTIMATES Mining operations at Caijiaying have embarked on an exciting phase of expansion with ongoing mine The Zone III Mineral Resource Estimate is defined by a total of 189 surface diamond drill holes, 32 reverse circulation surface drill holes and 4,801 underground diamond drill holes with an average spacing of approximately 20 metre x 20 metre, for a combined total of 633,940 metres of drilling. Underground mining operations at Zone III have achieved full development from 1,420mRL down to the lower mine licence boundary at the 1,000mRL. Production activities persist across all levels of operation, employing integrated primary, secondary and remnant production fronts. 10 Griffin MininG LiMitedConcurrently, exploration and resource diamond drilling at 6.8 million tonnes at 4.0% Zn, 0.7% Pb, 37.0g/t Ag and efforts focus on delineating near-mine mineralisation 0.7g/t Au. This estimation translates to approximately beneath and eastward of mine development. In total, 0.3 million tonnes of Zn, 0.05 million tonnes of Pb, 198 underground drill holes, spanning 25,981 meters, 8.1 million ounces of Ag and 0.16 million ounces of were drilled to facilitate both grade control and resource Au. The Zone VIII deposit is defined by a total of 44 definition objectives throughout 2023. diamond drillholes spaced at intervals of 50 to 100 metres amounting to a combined total of 32,193 metres. Zone V and VIII are situated within a mining retention licence adjacent to Zone II and III, covering a total area of 2.23 square kilometres and valid until the 16 July 2024. The Company is currently seeking to convert the retention licence to a mining licence. Mineral Resource Estimate The Global Mineral Resource that encompasses Zones III, II, V and VIII at a zinc cut-off grade of 1% and as amended for mining depletion at Zone III as of 31 December 2023 is summarised as follows. Zone II The updated 2023 Zone II Mineral Resource Estimate at a zinc cut-off grade of 1% using actual drilling as of July 2023 totals 38.2 million tonnes at 3.4% Zn, 0.9% Pb, 27.5g/t Ag and 0.2g/t Au. This results in total metal of approximately 1.3 million tonnes of Zn, 0.3 million tonnes of Pb, 33.8 million ounces of Ag and 0.26 million ounces of Au. A total of 109 surface diamond drillholes, 91 reverse circulation surface drillholes and 261 underground diamond drillholes, define the Zone II deposit at an average spacing of approximately 40 metre x 40 metre for a combined total of 116,317 metres of drilling. Five primary levels of capital development are under construction and, once completed, will provide comprehensive drill access to the entire 1.3 kilometre strike length of the Zone II Mineral Resource, extending to the lower designed level of 1030RL. Furthermore, extensive diamond drilling from the historic Zone II 1453 RL drill drive continues to delineate and define mineral resources with 98 underground diamond drill holes for 24,934 meters completed in 2023. Zone V There has been no on ground activity at Zone V throughout 2023 and therefore the Mineral Resource Estimate remains unchanged at 6.0 million tonnes at 3.2% Zn, 1.4% Pb, 56.0g/t Ag and 0.6g/t Au. This estimation yields approximately 0.2 million tonnes of Zn, 0.08 million tonnes of Pb, 10.8 million ounces of Ag and 0.12 million ounces of Au. The deposit at Zone V is defined by a total of 34 surface diamond drillholes, 3 reverse circulation surface drillholes with an average spacing of approximately 25 metre x 100 metres for a combined total of 15,242 metres of historical drilling. Zone VIII There was no on-ground activity at Zone VIII in 2023, and, therefore, the mineral resource remains unchanged 11 RepoRt and accounts 202312 Griffin MininG LiMitedPlan view of Zones II, III, V & VIII with surrounding licence areas 13 RepoRt and accounts 2023Caijiaying (continued) MINERAL RESOURCE ESTIMATES Caijiaying Zone III Remaining Mineral Resources Zone III Domain 1: Zn Resources > 1% Zn Tonnes (Mt) 22.1 5.8 3.5 31.4 Zn (%) 5.0 3.7 4.2 4.7 Pb (%) 0.3 0.2 0.3 0.2 Ag (g/t) 25.2 21.4 30.6 25.1 Au (g/t) Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 0.6 0.4 0.3 0.5 1,104 216 149 1,469 56 11 9 76 17,902 3,951 3,494 25,346 455 67 34 556 Zone III Domain 2: Au Resources > 0.5 g/t Au Tonnes (Mt) 0.6 0.1 0.0 0.7 Tonnes (Mt) 22.7 5.9 3.6 32.1 Tonnes (Mt) 1.6 1.2 2.8 4.3 11.8 19.3 35.4 4.3 13.4 20.5 38.2 Zn (%) 0.5 0.7 0.8 0.5 Zn (%) 4.9 3.7 4 4.6 Zn (%) 2.5 2.0 2.3 3.9 3.9 3.2 3.5 3.9 3.7 3.1 3.4 Pb (%) 0.1 0.0 0.1 0.1 Pb (%) 0.2 0.2 0.3 0.2 Ag (g/t) 17.2 9.6 7.7 15.9 Au (g/t) Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 2.2 0.9 0.7 2.0 3 1 0.1 4 0.5 0.04 0.01 1 323 32 2 357 42 3 0.2 46 Zone III: Total Ag (g/t) 25.0 21.2 30.6 24.9 Au (g/t) Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 0.7 0.4 0.3 0.6 1,107 216 150 1,472 57 11 9 76 18,225 3,983 3,496 25,704 497 70 35 601 Caijiaying Zone II Mineral Resources Zone II Oxide: Zn Resources > 1% Zn Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) Pb (%) 0.5 0.2 0.4 Ag (g/t) 20.2 9.4 15.6 Au (g/t) 0.2 0.1 0.2 39 24 63 Zone II Fresh: Zn Resources > 1% Zn 1.4 0.7 0.9 0.9 1.4 0.7 0.8 0.9 32.9 21.3 31.9 28.5 0.3 0.2 0.2 0.2 168 455 611 1,234 Zone II Total 32.9 21.2 30.6 27.5 0.3 0.2 0.2 0.2 168 494 635 1,297 8 3 11 60 84 170 313 60 92 173 325 1,025 360 1,386 4,520 8,108 19,779 32,407 4,520 9,134 20,139 33,793 12 4 17 45 72 123 240 45 84 127 256 Category Measured Indicated Inferred Sub-Total Category Measured Indicated Inferred Sub-Total Category Measured Indicated Inferred Total Category Indicated Inferred Sub-Total Measured Indicated Inferred Sub-Total Measured Indicated Inferred Total 14 Griffin MininG LiMited Caijiaying Zone V Mineral Resources Zone V Zn Resources > 1% Zn Category Inferred Total Tonnes (Mt) 6.0 6.0 Zn (%) 3.2 3.2 Pb (%) 1.4 1.4 Ag (g/t) 56.0 56.0 Au (g/t) 0.6 0.6 Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 191 191 84 84 10,819 10,819 116 116 Caijiaying Zone VIII Mineral Resources Zone VIII Domain 1: Zn Resources > 1% Zn Category Inferred Sub-Total Tonnes (Mt) 6.1 6.1 Zn (%) 4.4 4.4 Pb (%) 0.7 0.7 Ag (g/t) 36.0 36.0 Au (g/t) 0.5 0.5 Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 272 272 41 41 7,112 7,112 106 106 Zone VIII Domain 2: Au Resources > 0.5 g/t Au Category Inferred Sub-Total Tonnes (Mt) 0.7 0.7 Zn (%) 0.7 0.7 Pb (%) 0.7 0.7 Ag (g/t) 45 45 Au (g/t) 2.4 2.4 Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 5 5 5 5 1,012 1,012 54 54 Zone VIII Total Category Inferred Total Tonnes (Mt) Zn (%) Pb (%) Ag (g/t) Au (g/t) Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 6.8 6.8 4.0 4.0 0.7 0.7 37 37 0.7 0.7 277 277 46 46 8,124 8,124 160 160 Caijiaying Combined Global Mineral Resources 31 December 2023 Category Measured Indicated Inferred Total Tonnes (Mt) 27.0 19.3 36.8 83.1 Zn (%) 4.7 3.7 3.4 3.9 Pb (%) 0.4 0.5 0.8 0.6 Ag (g/t) 26.2 21.2 35.9 29.4 Au (g/t) Zn Metal (kt) Pb Metal (kt) Ag Metal (kOz) Au Metal (kOz) 0.6 0.2 0.4 0.4 1,274 711 1,252 3,237 117 103 312 531 22,745 13,116 42,578 78,440 542 154 438 1,134 Notes: The Caijiaying Mineral Resources are based on resource modelling work completed by ERM Australia Consultants Pty Limited (previously CSA Global) and reported in 2023 in accordance with JORC 2012 guidelines.

Generally, mineralisation at Zone III tends to dip steeply to moderately westward and extends along strike with a shallow 20 metre north plunge. Mining activity at Zone II is in its early stages, with geological data primarily sourced from diamond drill core. Unlike Zone III, Zone II features limited underground development for detailed underground geological mapping although this is set to change throughout 2024. Continued safe production and mine expansion at the Caijiaying Mine continue to be the core focus for the Company. While there have been no regional exploration activities, the Company continues administrative efforts to unlock the full exploration potential at the adjacent Zone V and Zone VIII project areas. In addition, research and site visits for potential project acquisitions occurred both within and outside Hebei province. 18 Griffin MininG LiMitedUnderground drilling at the Caijiaying Mine 19 RepoRt and accounts 202320 Griffin MininG LiMitedCaijiaying Mine Tailings Storage Facility 4 21 RepoRt and accounts 2023Caijiaying (continued) OPERATIONS Production at the Caijiaying Mine in 2023 and 2022 may be summarised as follows: Year to 31 December Ore mined Ore processed Zinc in concentrate Produced Gold in concentrate produced Silver in concentrate produced Tonnes Tonnes Tonnes Ozs Ozs Lead in concentrate produced Tonnes 2023 1,505,642 1,513,977 56,933 17,052 314,667 1,546 2022 852,579 831,549 31,787 10,137 224,587 940 2023 was, as forecast, the first year in the history of the and investigations were undertaken to identify the best Caijiaying Mine that sustained production at the enhanced available automated processes in China for deployment at rate of 1.5 million tonnes of ore was achieved.

This has enhanced safety awareness targeting local cultural attitudes and hazardous practices. beyond. This will be implemented with automation and Expansion of the Caijiaying Mine into Zone II commenced mechanisation. Mine automation is focused on the deployment of western technology to eliminate manual tasks. Key targets are paste fill systems, shotcrete, cable bolting and emulsion explosives being deployed with remote loading, all of which represent safe production improvements. The mill optimisation program is focused on automation and improving the efficient use and consumption of consumables. In 2023 trials began for grinding media in 2023 with the development of the Southern Ventilation shaft and underground development from Zone III. Expansion of Zone II is a three year project and by the end of 2023 access from the existing underground workings at Zone III was completed with work commencing on a third portal and internal declines. The development schedule for Zone II will see sustained ore produced from Zone II, as allowed under Chinese regulations, in the last six months of development, as part of the approval process and ramp up to full production. 22 Griffin MininG LiMited Regulatory permission to conduct exploration and resource The new dry stack Tailings Facility 4 (“TSF4”), phase drilling below 1000RL was granted in 2023. Application 1 uplift, was completed in April 2024 and the full safety for the conversion of the retention licence into a mining facility design approval is expected imminently. licence at Zone VIII, which will include work below the 1000RL, is now being prepared. Whilst the Life of Mine Plan continues to be reviewed, only minor amendments have been made with ongoing resource definition drilling mainly at Zone II. With continued drilling results and positive work in Zone III, the mine life continues to look well supported to 2050 and beyond. Future optimisation of the mine plan is focused on zero waste and renewable energy to reduce total capital spending and maintaining the current world class low operating costs. The 6MW solar facility was successfully commissioned without incident in August 2023. On a full utilisation day, this facility provides up to 30% of the Caijiaying Mine’s energy requirements. Future renewable energy deployment will be focused on expanding the solar, wind and battery systems utilising the same end user model that has proven successful with the solar project to utilise domestic green energy programs. The fourth TSF4 provides for a minimum of 3 lifts and minimum life span of 7.5 years. However, ongoing work to achieve zero waste is progressing with the objective of eliminating the need to construct any additional tailings facilities. The utilisation of mine tailings for bricks and construction material is being optimised with western technology and support by the Hebei Provincial Government which is funding a separate project into tailings utilisation. A primary objective for 2024 and beyond is to focus on sustainability. Continued development of the already strong local relationships will continue, including the deployment of next step trainee programs for non-university graduates in the form of skilled labour and supervision to create a sustainable local workforce with value-add potential. Commitment to operational improvements and the continual problem-solving approach required for world class technological deployment remains in place. The ability of the Caijiaying Mine to continually develop and improve is a testament to the success of the Company. 23 RepoRt and accounts 202324 Griffin MininG LiMitedConstruction of the Caijiaying Mine’s new southern ventilation shaft 25 RepoRt and accounts 2023FinanCial results SUMMARY In 2023 the Company and its subsidiaries (together the “Group”) recorded; • Revenues of $146,023,000 (2022: $94,397,000); • Gross profit of $51,842,000 (2022: $38,252,000); Operating (administration) expenses, excluding the Chinese partners profit share and share incentive scheme charges, rose by $854,000 (4.2%) from that in 2022.

Sustainability is supported by the Group’s values; operating in an environmentally responsible manner by continually improving circular and low-carbon operations including engagement in green partnerships, targeting zero waste, prioritising the health and safety and development of employees, conducting business with integrity throughout the Group and supply chain as well as actively engaging and contributing to the local community around the Caijiaying Mine. CARING FOR THE ENVIRONMENT for the Caijiaying Mine to be the sole consumer of energy generated from two 6.3MW wind turbines generating a total of 12.6MW of wind power. The wind turbines will be constructed within 2.5km of the Caijiaying Mine and connected to the current 36,000 volt mains electrical power lines. ZGNE is Hebei Hua Ao’s current partner for the fully operational 6MW Solar Farm facility located on the rehabilitated Tailings Facilities 1 and 2 at the Caijiaying Mine. This new wind turbine agreement is a natural extension of the already successful local partnership between Hebei Hua Ao and ZGNE. Once completed, the Caijiaying Mine will have 18.6MW of renewable electrical capacity at peak generation which exceeds the current 18.1MW peak usage. In accordance with current People’s Republic of China regulations, this is the maximum electrical capacity an independent private enterprise may develop. The project is expected to be completed within 12 months, including all approvals and construction. Hebei Hua Ao remains committed to 100% renewable energy. In addition to this renewable energy generation, The Caijiaying Mine is a PRC certified Green Mine Hebei Hua Ao is examining the installation of large- and has obtained ISO14001 environmental management scale battery storage capacity and the purchase of wind or systems (EMS) certification. The strategy adopted by solar energy directly from state owned renewable energy Hebei Hua Ao’s Green Mine Leading Group (led by projects in close proximity to the Caijiaying Mine to the Chief Operating Officer) is to improve mining achieve 100% renewable power at all times regardless of sustainability through its commitment to collaboration light or wind conditions. and innovative technology. Griffin Mining is committed to sustainable production and GREEN MINING AND EXPLORATION strict adherence to the County, Municipal, Provincial and Safety is Hebei Hua Ao’s core value with the objective of National objectives of the Green Mine Initiative. In the last 2.5 years Hebei Hua Ao has invested over Rmb150m in emission reduction, regenerative and sustainability projects. Sustainability is embedded throughout Hebei Hua Ao from the Board to the employees on site. Low environmental impact mining techniques are preferred using eco-friendly equipment; when mining waste cannot be reused, its harmful effects are mitigated as far as possible. Rehabilitation of tailings facilities is a key environmental project for Hebei Hua Ao. Hebei Hua Ao aims to achieve net zero through collaboration in local partnerships to produce green energy. zero harm for employees, contractors and visitors. Further information can be found in the social responsibility section of this review. Hebei Hua Ao’s current reported mineral resources are in excess of 80 million tonnes. The life of mine plan shows the mine to be profitable at a production rate of 1.5 million tonnes until at least 2050. Zone III is in production and Zone II is in development following the grant of a mining licence and approval of the safety facility design. Applications for mining licences for Zones V and VIII are underway. Underground mining is used to extract the resource which minimises the impact on the environment. Advanced ground control management techniques eliminate subsidence.

Hebei Hua Ao has adopted a sustainable ecologically responsible exploration strategy and engages with local communities to minimise disruption on the land where exploration is planned. A baseline study of vegetation is undertaken so that where indicators of potential geological anomalies are identified there is a bench mark for restoration of habitat. Exploration targets are pinpointed using non invasive airborne or satellite surveys. The choice of sampling technology and equipment minimises the exploration footprint as does the use of green drilling programmes. PROCESSING In 2023, Hebei Hua Ao obtained ISO9001 quality management systems (QMS) certification, thus demonstrating the systematic management of product quality. Hebei Hua Ao consistently meets product quality standards and requirements, optimises production process configurations, enhances digital construction and innovation, and monitors the concentrate grade and moisture content to meet customer expectations. A two-stage dewatering process consisting of thickener and ceramic filters keeps the moisture of the concentrate product at about 10%. The dewatered zinc concentrate is stored in bulk while the dewatered lead concentrate is packed in concentrate bags. Equipment and devices are checked and repaired regularly to maintain normal operations and stable processing and to further improve the product quality. In addition, Hebei Hua Ao has formulated an annual training plan to cover requirements for product quality and other special training for employees and regular meetings take place to deliver training to all employees. In 2023, Société Générale de Surveillance SA (SGS), an internationally recognised testing, inspection and certification organisation, conducted an audit of the laboratory’s sample collection and analysis processes and all the problems identified in the audit were rectified. WASTE A key element of the Green Mine Strategy is a commitment to zero waste. Operations are planned to reduce waste by deploying technology at all stages of the mining and processing operations. For example, advanced processing techniques enable circa 96% of contained zinc metal, circa The main production processes of Hebei Hua Ao include 65% of contained gold, circa 50% of contained silver and ore crushing, milling, lead flotation, zinc flotation, lead circa 70% of contained lead to be recovered in concentrate concentrate dewatering, zinc concentrate dewatering, and for sale. Sulphide minerals are eliminated allowing the other processes. tailings to be used safely in construction materials. If waste is reduced so will the requirement for remediation. In the ore crushing process, Hebei Hua Ao adopts a three- stage and one closed-circuit process to improve the ore Having minimised waste, Hebei Hua Ao is mindful of its crushing rate. Ore is screened and crushed again until it duty to manage the waste produced responsibly to protect meets the required granularity.

In the mine, online Total Suspended Particulate (TSP) monitors have been installed to ensure the concentration of particulate emissions meets emission standards. Advanced ventilation systems reduce dust and emissions. Tailings are dewatered and the water is reused thus achieving full recycling of all domestic and production wastewater. REHABILITATION Hebei Hua Ao has engaged in a continuous project of rehabilitation whilst the mine is in operation. Two tailings facilities have already been fully rehabilitated. The social licence to operate is fulfilled by ensuring the mine and surrounding environment are safeguarded using all available technology with a commitment to ecological The main air pollutant from the production process is dust. restoration and effective environmental management. The Covers and bag filters ensure dust collection efficiency of benefits of this approach are numerous, including: 98.5%. At the mine site, dry sweepers and water trucks are used with regular cleaning and water spraying to reduce the dust. Ore dumps are protected with windproof dust suppression nets. WASTE DISPOSAL Hazardous wastes are managed and stored before being removed by suitably qualified third parties for disposal. Noise management Blasting, mine machinery, the crushing, screening and grinding of aggregates as well as boiler room fans and mine ventilation fans all generate noise. As mining activity takes • Safer working conditions for employees • Improved relationships and contribution to the community • More profitable business • Less disruption and therefore more reliable production • The active support of local green energy investment • A reduction in future mine closure costs for Hebei Hua Ao and the local government • A reduction in environmental liability and risk • The potential identification and realisation of unforeseen opportunities • Improved reputation and shareholder value place below underground there is less impact than above In Green Energy partnerships, Hebei Hua Ao provides ground.

CAIJIAYING MINE The Caijiaying Mine’s metal production capability has been augmented with continued extensive exploration, expansion of the mill processing facilities (including grinding and flotation circuits) and ongoing underground infrastructure development. Exploration has been focused on identifying geological targets and evaluating the potential for significant additional resources. Whilst In addition, a large number of potential mining projects have been analysed worldwide. None have been successfully consummated for a myriad of reasons including country risk, negative findings during due diligence, a questionable return calculated for the risk shareholders would need to accept in funding the project to production, the overall project risk profile and various other deficiencies in grade, tonnes, metallurgy, depth and difficulty in mining. the existing Mineral Resource estimate confirms the CLIMATE CHANGE availability of extensive resources at the Caijiaying Mine for increased production, further resource additions will provide an opportunity to further increase the Caijiaying Mine’s production profile. This includes more extensive exploration not only at Zones II and III, but also at Zones V & VIII, which require extensive further drilling to fully understand the size and nature of these orebodies. Whilst the grant of a new mining licence over Zones II and III has enabled production rates to be raised to 1.5 million tonnes per annum, further expansion of operations will require further licences and permits from various Chinese authorities which are proving increasingly complex and time consuming to obtain. Griffin studies the possible impact of climate change on business operations and actively tackles climate change where it is able to do so. As well as recognising the benefits of increased metal prices as the world moves towards EV economies, this has involved identifying risks related to climate change such as extreme weather and sudden natural disasters including rainstorms, snowstorms, drought, etc. that may lead to power supply interruptions and production accidents, causing significant economic losses and threatening personal safety. Accordingly, Griffin has developed relevant measures to address these risks including back-up diesel generators and ensuring sufficient supplies of essential goods. The upgraded facilities can ensure the continued operation of underground ventilation, drainage and mill maintenance work in case of an emergency, thereby reducing the risk of underground workers being trapped due to power outages. 47 RepoRt and accounts 2023Corporate governanCe The board of directors of Griffin has responsibility for Two independent non-executive directors were appointed setting the overall strategy of the Group, its performance, to the Board in 2022 to join the Senior Independent management and financial matters including, the approval Director (“SID”), Clive Whiley.

The Company and its directors have adopted the Corporate Governance Code published by the UK Quoted Company Alliance (“QCA”) and are guided by the principles contained therein, so far as the Board of Directors is able and considers practicable. The Board meets on a quarterly basis, or as required, with all members in attendance in 2023. The executive Chairman leads the Board, and whilst not employed by the Company, he spends a significant part of his time on the Company’s business. The Chairman’s services are provided by Keynes Capital (see report of the Remuneration Committee on page 54). The Company has no Chief Executive Officer. Accordingly, the roles of Chief Executive Officer and Chairman have not been separated as recommended by the QCA Code, for the above reason. The other executive director is the full-time Finance Director. He is also the Company Secretary and, although not in accordance with best practice, it has not proved practicable to separate shareholdings of these three non-executive directors are less than 0.2% of the Company’s issued share capital and they are free from any business or other relationship which could materially interfere with the exercise of their independent judgement. Adam Usdan is not an independent non-executive director as he is also a major shareholder. The SID receives additional compensation to reflect his commitment to make 25% of his time available to help the Chairman with strategic support. The Chairman requires this support since he has the operational responsibilities of a Chief Executive Officer and the Board is of the view that the specialist nature of this support could not be sourced from the Company’s advisers. Notwithstanding the additional responsibilities and remuneration received by the SID, the Board’s judgement is that he remains an independent director as the additional responsibilities represent a minority of his employment and he is demonstrably independent in character and judgement. The SID supports the Chairman and executive director by regularly communicating with the major shareholders to build a strong relationship with them, other shareholders and potential investors. The Chairman and the Finance Director maintain regular contact with significant shareholders and the Company retains an office in London as a point of contact for all shareholders and potential shareholders in order to gauge the needs and expectations of shareholders in the Company. The SID supports the executive directors by regularly communicating with the major shareholders, other shareholders and potential investors. The Company updated its website during the year to improve communication with stakeholders. The Board is supported by the Audit Committee and Remuneration Committee.

THE ROLE OF THE REMUNERATION COMMITTEE The Remuneration Committee is responsible for determining and agreeing with the Company’s board of directors the broad policy for the remuneration and employment terms of the Finance Director, Chairman and other senior executives and, in consultation with the Chairman, for determining the remuneration packages of such other members of the executive management of the Group, as it is designated to consider. The Renumeration Nevertheless, the Remuneration Committee continues to assess various remuneration policies to attract and retain future high-calibre executives and motivate them to develop and implement the Group’s business strategy in order to optimise long-term shareholder value. It is intended that such policy will build on past practice and apply in the future. The policy is being framed around the following key principles: • Total rewards will be set at levels that are sufficiently competitive to enable the recruitment and retention of high-calibre executives; Committee is also responsible for the review of, and making • Total incentive-based rewards will be earned through recommendations to, the board of directors in connection the achievement of performance conditions consistent with share option plans and performance related pay and with shareholder interests; their associated targets and for the oversight of employee benefit structures across the Group. • The design of long-term incentives will be prudent and will not expose shareholders to unreasonable financial Apart from the Finance Director, all the other executives risk; engaged by the Griffin Group are either employed • In considering the market positioning of reward by operating subsidiaries or independent contractors elements, account will be taken of the performance of (contracting through professional service companies). the Group and of each individual executive director; Almost all of these executives or service companies are and employed or retained by Hebei Hua Ao.

This Remuneration Committee report includes a summary of the remuneration policy and the Annual Report on Remuneration. • Reward practice will conform to best practice standards as far as reasonably practicable. When formulating the scale and structure of remuneration, the Remuneration Committee considers a number of different factors including market practice and external market data of the level of remuneration offered to directors of similar type and seniority in other companies of the size and activities of the Company. In addition, the pay and employment conditions of employees are also considered when determining directors’ remuneration. The Remuneration Committee may also seek advice from external consultants where appropriate.

These shares were issued and admitted to trading on 8 January 2024. On 12th January 2024, Roger Goodwin completed the sale of 1,350,000 shares in the Company at 88 pence per share, following which he holds 1,527,830 Ordinary Shares in the Company representing 0.8% of the issued share capital of the Company. ** Mr. Adam Usdan is interested in 28,794,878 shares in Griffin representing 15.6% of the Company’s issued share capital, 7,960,221 of which are held directly with the remaining 20,834,657 shares being held by Trellus Partners LLP, the General Partner of a Limited Partnership in which Mr. Usdan has a controlling interest. Other than this, all the directors interests disclosed are beneficial. On 13 February 2014 options (the “40 pence options”) over 5,000,000 new ordinary shares were granted to directors and key employees of the Company. All of which have now vested and have been exercised . Each 40 pence option entitled the holder to subscribe for new ordinary shares in the Company at an exercise price of £0.40 per share on or before 31 December 2023. On 6 February 2015 the Board resolved to adopt a new share option scheme (the “30 pence options”) over a total of 20,000,000 new ordinary shares in the Company. All of which have vested and have been exercised. Each 30 pence option entitled the holder to subscribe for new ordinary shares in the Company at an exercise price of 30 pence per new ordinary share on or before 31 December 2023. As part of a rationalisation of the capital structure of the Company, an offer was made on 30 December 2022 to option holders for the purchase and cancellation of outstanding options over 19,520,000 shares in the Company (“the Offer”). Acceptances were received from option holders in respect of options to purchase 17,520,000 shares in the Company which were subsequently purchased and cancelled, which, based on the mid-market price on the Offer date of 76 pence per share, resulted in 10,130,526 new ordinary shares being issued pursuant to the Offer for nil consideration. In March 2023 the Company implemented a Share Incentive Plan (the “Plan”), to retain vital key Company personnel, in particular the Chairman, Mladen Ninkov. On 4 April 2023 7,805,000 shares were issued under the terms of the Plan, including 6,000,000 new ordinary shares to Mladen Ninkov. Following this issue Mladen Ninkov has an interest in 6,033,001 shares in the Company, representing 3.1% of the Company’s issued share capital. The new Ordinary Shares issued are subject to certain contractual terms including that the shares issued will not be sold or otherwise transferred or disposed of before 31 December 2024 except in the event of a transaction occurring with the Company, and that the shares issued will be returned in the event of malus and returned pro rata upon leaving the employment of the Company or its subsidiaries before 31 December 2024. SHARE BUYBACK On 12 September 2023, the Company announced that in light of the severely undervalued nature of the Company’s share price, the cash generated by operations in conjunction with the available funds available outside of China to Griffin and the current depressed nature of base metals prices and the share prices of those producers, the Directors resolved to renew efforts to successfully effect the share buy-back programme announced on 25 February 2021 (the “Buy-Back Programme”) to return excess monies not required to meet financial and working capital requirements to shareholders. The directors have since extended the buy-back programme to 26 August 2024 to purchase up to 10 million shares and up to a value of $10 million, and provided sufficient funds are available, they may seek to extend the buy-back programme in the same terms again. In addition to the Buy-Back Programme, the directors reserved the right (subject to compliance with applicable law) to: 1) purchase large blocks of shares from individual shareholders where the large number of such shares offered in the market may cause instability in the Company’s share price; and 2) purchase a larger number of shares via a tender offer which would be the subject of further documentation being sent to non-US resident shareholders. 61 RepoRt and accounts 2023direCtors’ report (continued) On 5 January 2024 the Company entered into trades committing to purchase, through its joint broker Joh. Berenberg, Gossler & Co. KG, 8,886,128 of the Company’s own ordinary shares (“Ordinary Shares”), representing 4.6% of the Company’s issued share capital (excluding shares already held in treasury), at a price of 88 pence per Ordinary Share, for a total consideration of £7,819,792 ($9,672,000), excluding brokers fees, (the “Transaction”). The Transaction was conducted separately from the Company’s latest share buyback programme. On 15 March 2024, 10,297,943 ordinary shares in the Company purchased under share buyback programmes were cancelled. Following the cancellation of these shares, there are now 184,530,477 ordinary shares in issue with no outstanding options or warrants. SUBSTANTIAL INTERESTS Apart from Adam Usdan’s interests in the share capital of the Company, the Company has been notified that: - On 22 January 2021 Andrew Goffe and controlling undertakings held an interest in 26,513,657 ordinary shares in the Company representing 15.227% of the Company’s then issued share capital. On 5 January 2024 he sold 112,500 shares in the Company as part of the buyback Transaction; and - On 1 March 2021 Richard Griffiths and controlling undertakings held an interest in 24,313,224 ordinary shares in the Company representing 13.93% of the Company’s then issued share capital, together with voting rights through financial instruments equating to 3.34% of the Company’s then issued share capital. On 5 January 2024 he sold 7,423,628 shares in the Company as part of the buyback Transaction. PRINCIPAL RISKS AND UNCERTAINTIES Risk Comment Business Impact Mitigation Economic Risk Exposure to a fall in zinc, gold, silver and lead metal prices. Revenue is dependent upon metal prices. High In common with other mining companies operating in China the Group sells its products by auction to local smelters and agents, however, Griffin continues to review the appropriateness of hedging and indicative cost of put options. Exposure to fluctuations in the Renminbi / US dollar exchange rate. A fall in the value of the Renminbi would reduce the US dollar value of revenues, whilst an increase in the value of Renminbi would increase operating costs. Moderate The Renminbi is loosely pegged to the US dollar. Management continually reviews foreign exchange rates and the appropriateness of hedging. Country Risk Exposure to political and social risks in the PRC. Exposure to changes in fiscal and regulatory regime. Low High Griffin’s primary assets are located in the PRC and therefore exposed to any adverse changes in the political and social situations there. to political/social is exposed to changes risks, In addition the Group in permitting, environmental, health and safety, and tax regulations in the PRC which may result in a more challenging, or costly, operating environment. The Group has operated in the PRC for over 25 years in which time the country has been relatively stable, and retains good relationships with PRC authorities. Griffin actively engages and works with the local PRC authorities and agencies to identify and minimise the impact of changes in PRC regulations. 62 Griffin MininG LiMitedprinCipal risks and unCertainties Continued Risk Comment Business Impact Mitigation Operational Risk Reliance on Third Party Contractors for particularly Griffin uses a number of unrelated contractors, its mining, haulage and drilling activities. Each of these activities has inherent risk, including injury or death to the contractor’s employees. Such events could cause a total shutdown of all operational activities which may take a substantial time to recommence. Exposure to mining hazards The Group is exposed to a number of risks and hazards typically associated with mining for example rock falls, flooding and mechanical breakdowns. Moderate Griffin has an extensive occupational Health and Safety Department in conjunction with a Mining Manager and his team of underground foreman who constantly oversee all contractors’ activities, inter alia, punishing and fining contractors for safety breaches. Griffin keeps under consideration moving to owner operated activities. Moderate Griffin’s operational teams continually monitor mining and other risks, and report to senior management who report to the Board of directors, taking immediate and appropriate measures to minimise any such risks and hazards identified. In addition, the Group’s operations are continually monitored by the PRC Safety and environmental Bureaus. Low High Reliability of Mineral Resources and Ore Reserves The calculation of Mineral Resources and Ore Reserves involves significant assumptions and estimates that may prove inaccurate. Mine fatality A fatality in the mine would result in the closure of the mine and suspension of operations for an indefinite time to allow a full investigation by the PRC authorities with subsequent penalties possibly including fines, dismissal of personnel held responsible, and loss of licences. Griffin’s Mineral Resources and Ore Reserve estimates are prepared by third party consultants, based in Australia, who are deemed “experts” under the JORC Code. immediate As noted above, Griffin’s operational teams continually monitor mining and other risks and report to senior management who report to the Board, taking appropriate measures to minimise any identified risks and hazards. In addition, the Group’s operations are monitored and continually inspected by the PRC local, County, City and Provincial Safety Bureaus. and Other Risks Exposure to single operation Griffin is reliant upon a single operation, being the Caijiaying Zinc Gold mine in the PRC. Factors affecting operations at Caijiaying have an impact upon the Group. Licence administration Griffin, its through subsidiary companies, holds a number of mining, exploration and other licences and permits to operate. These normally ongoing include operation and require periodic renewal. Renewals are not guaranteed. conditions for Moderate High It is the Company’s policy to pursue growth opportunities through expansion in the Caijiaying area, as well as reviewing acquisition opportunities which can be shown to be value accretive.

Their death, retirement or departure may have significant effect on the operations of the Company. Business Impact High Mitigation Griffin has contractual arrangements with all key employees which are renewed on a regular basis. Geological and Historical Information The loss of historical and/or geological information would have a very significant impact on the operations of the Company. Low Bribery and Corruption. Moderate Whilst strict internal policies and procedures to ensure compliance with applicable laws are applied to prohibit all forms of bribery and corruption the risk remains that employees or contractors have circumvented these policies and procedures which could result in prosecution of the Group and its officers. Pandemic (Covid-19, SARS etc) A further outbreak of Covid-19 or other virus may lead to restrictions on operations being imposed by the PRC authorities including a suspension in operations. Moderate Climate Change Climate change may have an impact on operations and demand for metals Low Griffin has instituted a complete back up system relating to all geological and operational data in Perth, Western Australia, with ERM formerly CSA Global. It is updated on a daily basis. The Group prohibits bribery and corruption in any form by directors, employees or by those working for and / or connected with the business. With the advice and support of the Group’s lawyers the Group has implemented anti bribery and corruption policies and procedures including: anti-bribery instruction to staff and third party contractors; on-going monitoring, including setting up reporting channels; and regular review of antibribery reporting policies and procedures. China imposed strict controls to control the Covid-19 and SARS outbreaks emerging from these relatively quickly. Griffin works closely with the PRC authorities to minimise the impact of such outbreaks upon personnel and operations. Griffin studies the possible impact of climate change on operations, identifying risks that may interrupt operations and develops measures to counter these. POST BALANCE SHEET EVENTS AND GOING CONCERN On 15 March 2024, 10,297,943 ordinary shares in Griffin Mining Limited (“the Company”) purchased under share buyback programmes were cancelled. Following the cancellation of these shares, there are now 184,530,477 ordinary shares in issue with no outstanding options or warrants. Otherwise there were no significant post balance sheet events requiring adjustment to the financial statements or disclosure. 64 Griffin MininG LiMitedGoing Concern Whilst it is difficult to accurately predict future profitability and liquidity, particularly regarding the impact of metal prices, the directors consider that at current metal prices and with the benefit of agreed banking facilities the Group can continue as a going concern for the foreseeable future without the need to curtail operations. The Group regularly prepares cash flow forecasts and revises its budgets and Life of Mine Plan to adapt to changing situations, including that relating to climate change, as the need arises. These have been extended for more than a year and adapted for a number of plausible scenarios to confirm that in all cases the Group could maintain liquidity cover. Amongst other matters management has taken into account sensitivities for the possible impacts of restrictions imposed by the Chinese authorities during sensitive periods, such as Chinese Communist Party Congresses, and / or to contain outbreaks of Covid-19 or other pandemics. With this in mind a three month suspension has been built into the cash flow forecasts on a severe case scenario. This is further considered in the notes to the financial statements on page 78. INDEPENDENT AUDITORS PricewaterhouseCoopers LLP were re-appointed auditors at the Annual General Meeting of the Company held on 7 July 2023 and have indicated their willingness to continue in office as auditors to the Company and a resolution proposing their appointment will be put to the forthcoming Annual General Meeting STATEMENT OF DIRECTORS’ RESPONSIBILITIES IN RESPECT OF THE FINANCIAL STATEMENTS The directors are responsible for preparing the financial statements in accordance with applicable law and regulation. The Bermuda Companies Act 1981 requires the directors to prepare financial statements for each financial year. Under that law the directors have prepared the financial statements in accordance with International Financial Reporting Standards (“IFRSs”) as adopted by the European Union. The directors must not approve the financial statements unless they are satisfied that the financial statements give a true and fair view of the state of affairs of the Group and of the profit or loss of the Group for that period. In preparing the financial statements, the directors are responsible for: • • selecting suitable accounting policies and then applying them consistently; stating whether applicable IFRSs as adopted by the European Union have been followed, subject to any material departures disclosed and explained in the financial statements; • making judgements and accounting estimates that are reasonable and prudent; and • preparing the financial statements on the going concern basis unless it is inappropriate to presume that the Group will continue in business. The directors are also responsible for safeguarding the assets of the Group and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities. The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Group’s transactions and disclose with reasonable accuracy at any time the financial position of the Group, and enable them to ensure the financial statements comply with applicable law and regulation. DIRECTORS’ CONFIRMATIONS In the case of each director in office at the date the Directors’ Report is approved: • • so far as the director is aware, there is no relevant audit information of which the Group’s auditors are unaware; and they have taken all the steps that they ought to have taken as a director in order to make themselves aware of any relevant audit information and to establish that the Group’s auditors are aware of that information This report was approved by the Board and signed on its behalf by: Roger Goodwin Finance Director and Company Secretary 14 May 2024 65 RepoRt and accounts 2023independent auditors’ report to the members oF griFFin mining limited report on the audit oF the group FinanCial statements opinion In our opinion, Griffin Mining Limited’s Group financial statements (the “financial statements”): • give a true and fair view of the state of the Group’s affairs as at 31 December 2023 and of its profit and cash flows for the year then ended; • have been properly prepared in accordance with IFRSs as adopted by the European Union; and • have been prepared in accordance with the requirements of the Companies Act 1981 (Bermuda). We have audited the financial statements, included within the Report and Accounts 2023 (the “Annual Report”), which comprise: the Consolidated Statement of Financial Position as at 31 December 2023; the Consolidated Income Statement, the Consolidated Statement of Comprehensive Income, the Consolidated Statement of Changes in Equity, and the Consolidated Cash Flow Statement for the year then ended; and the notes to the financial statements, which include a description of the material accounting policies. Our opinion is consistent with our reporting to the Audit Committee. basis For opinion We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs (UK)”) and applicable law. Our responsibilities under ISAs (UK) are further described in the Auditors’ responsibilities for the audit of the financial statements section of our report. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Independence We remained independent of the Group in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, which includes the FRC’s Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. our audit approaCh Overview Materiality • Overall Group materiality: $1.2 million (2022 : $1.1 million), based on 5% of the 3-year average profit before tax. • Performance Group materiality: $0.9 million (2022: $0.8 million). Audit scope • We conducted full scope audits of three components out of the Group’s ten entities which were selected due to their size and risk characteristics. Seven of the entities within the Group were financially inconsequential to the Group. • This enabled us to obtain 100% coverage of consolidated revenue, 99% coverage of consolidated profit before tax and 99% coverage of total assets for the Group. Key Audit Matters • Impairment assessment of property, plant and equipment. 66 Griffin MininG LiMited independent auditors’ report to the members oF griFFin mining limited The scope of our audit As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements. Key audit matters Key audit matters are those matters that, in the auditors’ professional judgement, were of most significance in the audit of the financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) identified by the auditors, including those which had the greatest effect on: the overall audit strategy; the allocation of resources in the audit; and directing the efforts of the engagement team. These matters, and any comments we make on the results of our procedures thereon, were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. This is not a complete list of all risks identified by our audit. COVID-19 and Extension of the business licence were key audit matters in the prior year, but are now removed on the basis that they are not considered sufficiently significant to this year’s audit. Otherwise the key audit matters below are consistent with last year. key audit matter how our audit addressed the key audit matter Impairment assessment of property, plant and equipment Refer to Note 1 (Significant Judgements and Estimates We obtained management’s impairment assessment and section) and to Note 12, Property, Plant and Equipment. performed the following audit procedures: As at 31 December 2023, the carrying value of the mining - we met with, and obtained written correspondence assets totalled $250.4 million. As disclosed in Note 12, management assessed the mining assets for impairment indicators and concluded that there were no impairment indicators as at 31 December 2023; accordingly, there is no requirement to perform an impairment test. Notwithstanding this, management has undertaken such an assessment based on the new life of mine plan in line with good practice and governance as well as in line with their established internal policy. As a result, we have reviewed management’s assessment. from, management’s external legal advisors to obtain evidence that the conversion of the legal structure of the existing joint venture, and therefore extending the term of the business licence, will be routine in nature and that no additional costs will be incurred; - we understood and evaluated management’s processes and controls in respect of the impairment trigger assessment process; - we evaluated and challenged management’s assessment and judgements including ensuring that the impact of climate change, and recent commodity price The 2023 life of mine plan, which includes extraction and foreign exchange volatility, were appropriately of resources from Zone II and Zone III, extends to 2050. considered in management’s impairment assessment Under the terms of the Group’s current joint venture and conclusions. agreement with Zhangjiakou Caijiaying Lead Zinc Mining, the Group’s business licence will expire in 2037. The joint venture agreement will legally convert into a limited liability company by 1 January 2025. Management prepared a detailed cash flow model on a FVLCD basis to estimate the recoverable amount. Our procedures in respect of the impairment model included: - verifying the integrity of formulae and the mathematical accuracy of management’s valuation model; 67 RepoRt and accounts 2023independent auditors’ report to the members oF griFFin mining limited key audit matter (continued) how our audit addressed the key audit matter (continued) Judgement is needed as to whether this conversion to a - consideration of the impact of the latest life of mine limited liability company would enable an extension of plan assumptions and ensuring that the impairment the term of the business licence as a matter of routine, model reflected the latest plans; and if it would lead to additional cost being incurred. This impacts asset carrying amounts and depreciation rates because a shorter business licence would reduce the amount of resources that could be extracted. Management has appointed legal advisors to convert the joint venture agreement to a limited liability company. Based on legal advice management expects to be able to extend the term of the business licence as a matter of routine - assessing the reliability of management’s forecast capital and operating expenses with reference to comparing budgeted results with actual performance in prior periods; - using our independent valuation experts to assist us in evaluating the appropriateness of the discount rate used and whether it fell within a reasonable range taking into account external market data; and at no additional cost, and therefore has concluded it is - benchmarking management’s forecast commodity reasonable to assume the life of mine goes out to 2050. price and foreign exchange assumptions against our own collated consensus data to assess whether they fell within an external analyst range; - assessing whether the assumptions had been determined and applied on a consistent basis, where relevant, across the Group; - assessing the disclosure made over the impairment assessment and the sensitivities within Note 12 of the financial statements and challenging management where any inconsistencies were noted. We did not identify any significant issues through our work performed. The determination of recoverable amount, being the higher of value in-use (“VIU”) and fair value less costs of disposal (“FVLCD”), requires judgement and estimation on the part of management in identifying and then determining the recoverable amounts for the relevant cash generating unit (“CGU”), which is considered to be the Caijiaying Mine. Recoverable amounts are based on management’s view of key value driver inputs and external market conditions such as future commodity prices, budgeted operating expenditure, the timing and approval of future capital expenditure, the most appropriate discount rate and foreign exchange rate. Estimation uncertainty is considered to be significant due to the long lives of the assets and uncertainty in the quantum and timing of cash flows, including the uncertain impact of climate change on the Group’s operations, as described in Note 12 to the financial statements. We focused on this area due to the material nature of the balance and the estimates and judgements involved in the impairment indicator assessment. How we tailored the audit scope We tailored the scope of our audit to ensure that we performed enough work to be able to give an opinion on the financial statements as a whole, taking into account the structure of the Group, the accounting processes and controls, and the industry in which it operates. Griffin Mining Limited is a Bermuda company listed on the Alternative Investment Market (“AIM”). The Group’s principal operation is the Caijiaying zinc mine in China. In establishing the overall approach to the Group audit, we determined the type of work that needed to be performed by us, as the Group audit team, or by the component auditors in China. 68 Griffin MininG LiMitedindependent auditors’ report to the members oF griFFin mining limited Our Group audit scope focused primarily on the Caijiaying zinc mine in China, which was subject to a full-scope audit by the local component auditors. We determined the level of involvement, oversight and direction we needed to have in the audit work to be able to conclude whether sufficient appropriate audit evidence had been obtained. A full scope audit was also performed over the parent company and a service entity by the Group team. The above gave us coverage of 100% of consolidated revenue, 99% coverage of consolidated profit before tax and 99% coverage of total assets for the Group. To ensure sufficient oversight of the Chinese component audit, the Group team performed a number of procedures throughout the audit to direct and oversee the audit approach. This included travelling to Beijing to visit the mine site with management and our local team, performing in-person file reviews, holding regular dialogue via video conference calls and other forms of communication as considered necessary to satisfy ourselves as to the appropriateness of audit work performed by the component audit team. The Group engagement team directly performed the audit of the consolidation. This, together with additional procedures performed at the Group level, gave us the evidence we needed for our opinion on the Group financial statements as a whole. The impact of climate risk on our audit As part of our audit, we made enquiries of management to understand their process to assess the extent of the potential impact of climate change risks on the Group and its financial statements. We used our knowledge of the Group to consider the completeness of the risk assessment performed by management, giving consideration to both physical and transition risks, and management’s own reporting and announcements. Whilst the impact is uncertain, we particularly considered the impact of both physical and transition risks arising due to climate change on the recoverable value of the Group’s property, plant and equipment. We also read the disclosures made in relation to climate change, in the other information within the Annual Report, and considered their consistency with the financial statements and our knowledge from our audit. Materiality The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both individually and in aggregate on the financial statements as a whole. Based on our professional judgement, we determined materiality for the financial statements as a whole as follows: Overall materiality $1.2 million (2022: $1.1 million). How we determined it 5% of the 3-year average profit before tax. Rationale for benchmark applied Profit is the key indicator of the Group’s performance and the most appropriate benchmark for materiality. Due to volatility in commodity prices which has impacted profitability, we have used a 3-year average profit before tax as the benchmark. For each component in the scope of our Group audit, we allocated a materiality that is less than our overall Group materiality. The range of materiality allocated across components was between $200,000 and $1,000,000. We agreed with the Audit Committee that we would report to them misstatements identified during our audit above $60,000 (2022: $55,000) as well as misstatements below that amount that, in our view, warranted reporting for qualitative reasons. 69 RepoRt and accounts 2023independent auditors’ report to the members oF griFFin mining limited ConClusions relating to going ConCern Our evaluation of the Directors’ assessment of Group’s ability to continue to adopt the going concern basis of accounting included: • Obtaining and reviewing the Group’s cash flow forecasts for the going concern period, challenging the assumptions used by management and verifying that these were consistent with our existing knowledge and understanding of the business, as well as with the Board-approved budget; • Obtaining evidence from the Group’s external legal advisors that the conversion of the legal structure of the joint venture into a limited liability company by 1 January 2025 will not negatively impact the cash flows of the Group over the going concern period; • Reviewing the Group’s cash flow forecasts under the severe but plausible downside scenario, evaluating the assumptions used, and verifying that the Group is able to maintain liquidity within the going concern period under these scenarios; • Testing the model for mathematical accuracy; and • Assessing the adequacy of the disclosure provided in Note 1 of the financial statements. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Group’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue. In auditing the financial statements, we have concluded that the Directors’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate. However, because not all future events or conditions can be predicted, this conclusion is not a guarantee as to the Group’s ability to continue as a going concern. Our responsibilities and the responsibilities of the Directors with respect to going concern are described in the relevant sections of this report. reporting on other inFormation The other information comprises all of the information in the Annual Report other than the financial statements and our auditors’ report thereon. The Directors are responsible for the other information. Our opinion on the financial statements does not cover the other information and, accordingly, we do not express an audit opinion or, except to the extent otherwise explicitly stated in this report, any form of assurance thereon. In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If we identify an apparent material inconsistency or material misstatement, we are required to perform procedures to conclude whether there is a material misstatement of the financial statements or a material misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report based on these responsibilities. responsibilities For the FinanCial statements and the audit Responsibilities of the Directors for the financial statements As explained more fully in the Statement of Directors’ Responsibilities in respect of the Group financial statements, the Directors are responsible for the preparation of the financial statements in accordance with the applicable framework and for 70 Griffin MininG LiMitedindependent auditors’ report to the members oF griFFin mining limited being satisfied that they give a true and fair view. The Directors are also responsible for such internal control as they determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the Directors are responsible for assessing the Group’s ability to continue as a going concern, disclosing as applicable, matters related to going concern and using the going concern basis of accounting unless the Directors either intend to liquidate the Group or to cease operations, or have no realistic alternative but to do so. Auditors’ responsibilities for the audit of the financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. Our audit testing might include testing complete populations of certain transactions and balances, possibly using data auditing techniques. However, it typically involves selecting a limited number of items for testing, rather than testing complete populations. We will often seek to target particular items for testing based on their size or risk characteristics. In other cases, we will use audit sampling to enable us to draw a conclusion about the population from which the sample is selected. Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below. Based on our understanding of the Group and industry, we identified that the principal risks of non-compliance with laws and regulations related to unethical and prohibited business practices and compliance with the regulations of the Ministry and Land and Resources of the PRC, and we considered the extent to which non-compliance might have a material effect on the financial statements. We also considered those laws and regulations that have a direct impact on the financial statements such as the Companies Act 1981 (Bermuda). We evaluated management’s incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls), and determined that the principal risks were related to posting inappropriate journal entries to manipulate results, and management bias in key accounting estimates. The Group engagement team shared this risk assessment with the component audit team so that they could include the appropriate audit procedures in response to such risks in their work. Audit procedures performed included: • Enquiries of the Directors, management and the Group’s legal counsel, including consideration of known or suspected instances of non-compliance with laws and regulations and fraud; • Evaluation of management’s controls designed to prevent and detect irregularities; • Review of minutes of meetings of the Board of Directors; • Challenging assumptions and judgements made by management in relation to their significant accounting judgements and estimates; and • Identifying and testing journal entries, in particular any journal entries posted with unusual account combinations. There are inherent limitations in the audit procedures described above. We are less likely to become aware of instances of non-compliance with laws and regulations that are not closely related to events and transactions reflected in the financial statements. Also, the risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one 71 RepoRt and accounts 2023independent auditors’ report to the members oF griFFin mining limited resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations or through collusion.

The material accounting policies adopted are detailed below. These policies have been consistently applied to all years unless otherwise stated. aCCounting Convention The financial statements have been prepared under the historical cost convention. new and amended standards adopted by the group The Group has applied the following standards and amendments for the first time for their annual reporting period commencing 1 January 2023: • Insurance Contracts IFRS 17; • Definition of Accounting Estimates - amendments to IAS 8; • Deferred Tax related to Assets and Liabilities arising from a Single Transaction - amendments to IAS 12; and • Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2. The amendments listed above did not have any impact on the amounts recognised in the current period and are not expected to significantly affect future periods. new standards and interpretations not yet adopted At the date of authorisation of these financial statements, certain new and amended accounting standards and interpretations have been published that are not mandatory for the year ended 31 December 2023, nor have they been early adopted by the Group. These standards and interpretations are not expected to have a material impact on the Company’s consolidated financial statements in the current or future reporting periods. • International Tax Reform - Pillar Two Model Rules - amendments to IAS 12. going ConCern The financial statements have been prepared on a going concern basis. The Group regularly prepares cash flow forecasts and revises its budgets and Life of Mine Plan to adapt to changing situations including that relating to climate change, as the need arises. These have been extended for more than a year and adapted for a number of severe but plausible scenarios to confirm that in potential adverse cases the Group could maintain liquidity cover. Amongst other matters management has taken into account sensitivities for the possible impacts of additional restrictions imposed by the Chinese authorities during politically sensitive periods and to contain outbreaks of Covid-19 or other pandemic. Apart from a suspension in operations during and in the lead up to the winter Olympics at Chongli in the first quarter of 2022, and during the PRC National Party Congress in September and October 2022 there have been no significant interruptions to operations at Caijiaying since the initial outbreak of Covid-19. However, a three month suspension has been built into the cash flow forecasts on a severe case scenario in the second half of 2024. The directors have considered that Hebei Hua Ao will be converted to a limited liability company with a new business licence by 31 December 2024 enabling Hebei Hua Ao to continue as a going concern. On the aforementioned bases the board of directors consider the Group will be able to meet its liabilities as they fall due for at least 12 months from the date of this report and have prepared the financial statements on a going concern basis. Consolidation basis The Group financial statements consolidate the financial statements of the Company and all its subsidiary undertakings drawn up to 31 December each year. Subsidiaries are entities over which the Group has the power to control the financial and 78 Griffin MininG LiMitednotes to the FinanCial statements Consolidation basis (continued) operating policies so as to obtain benefits from their activities. The Group obtains and exercises control through voting rights. Management has assessed its involvement in Hebei Hua Ao and Hebei Sino Anglo in accordance with IFRS 10 and concluded that it has control. In making its judgement, management considered the Group’s voting rights, the relative size and dispersion of the voting rights held by other shareholders and the extent of recent participation by those shareholders in general meetings. Unrealised gains on transactions between the Group and its subsidiaries are eliminated. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Amounts reported in the financial statements of subsidiaries have been adjusted where necessary to ensure consistency with the accounting policies adopted by the Group. revenue Revenue is measured by reference to the fair value of consideration received or receivable by the Group and comprises amounts received, net of VAT and production royalties, from sales of metal concentrates to third party customers. Sales are recognised on a delivery or collection basis as at this point the performance obligations are satisfied. Delivery or collection occur following open auction of metals in concentrate and where delivery is taken and cash received within 30 days of the agreement. non Current assets Intangible assets – exploration cost Expenditure on licences, concessions and exploration incurred on areas of interest by subsidiary undertakings are carried as intangible assets until such time as it is determined that there are both technically feasible and commercially viable resources within each area of interest and the necessary finance is in place, at which time such costs are transferred to property, plant and equipment to be amortised over the expected productive life of the asset. Until such time intangible assets are not depreciated. The Group’s intangible assets are subject to periodic review at least annually by the directors for impairment. Exploration, appraisal and development costs incurred in respect of each area of interest which are determined as unsuccessful are written off to the income statement. Property, plant and equipment Mine development expenditure for the initial establishment of access to mineral reserves, together with capitalised exploration, evaluation and commissioning expenditure, and costs directly attributable to bringing the mine into commercial production are capitalised to the extent that the expenditure results in significant future benefits. Property, plant and equipment are shown at cost less depreciation and provisions for the impairment of value (see note 12). Residual values Material residual value estimates are updated as required, but at least annually and where adjustments are required these are made prospectively. Depreciation Depreciation rates reflect the term of operations, extractable resource, and economic lives of the assets as follows: • Mine acquisition, development, licence, pre production and land use rights (included in mineral interests) - on a unit of production basis. • Plant and buildings - over 25 years on a straight line basis with a 10% residual value. • Dry tailings facility - over 15 years on a straight line basis with no residual value. • Mechanical equipment - over 10 years on a straight line basis with a 10% residual value. • All other equipment, including vehicles and office equipment - over 5 years on a straight line basis with a 10% residual value. 79 RepoRt and accounts 2023notes to the FinanCial statements impairment A review for impairment indicators at each reporting date is undertaken. In the event of impairment indicators being identified, an impairment test is carried out to assess whether the net book value of the capitalised costs in each area of interest (cash generating unit) is covered by the discounted future cash flows from resources within that area of interest. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount, which is the higher of fair value less costs of disposal or value in use. Management estimates expected future cash flows from each cash-generating unit and determines a suitable discount rate in order to calculate the present value of those cash flows. The data used for impairment testing procedures are directly linked to the Group’s latest approved budget, resource estimates, and life of mine plan. Estimates and assumptions used in determining whether an asset has become impaired are set out in note 12. Impairment assessments are based upon a range of estimates and assumptions: Estimates / Assumptions Basis • Future production: Measured and indicated resource estimates together with processing capacity • Capital expenditure: Development meterage at mining cost rates plus sustaining plant and equipment • Commodity prices: Current market and expectations of longer term price estimates and deductions for smelter treatment charges • Exchange rates: Current market exchange rates • Discount rates: Cost of capital risk mine Closure Costs Mining operations are generally required to restore mine and processing sites at the end of their lives to a condition acceptable to the relevant authorities and consistent with the Group’s environmental policies. Whilst the Group strives to maintain, and where possible, enhance the environment of the Group’s processing sites, provision is made for site restoration costs in the financial statements in accordance with local requirements (see note 24) which is anticipated to be greater than the actual costs of site restoration. inventories Inventories are valued at the lower of cost or net realisable value. Costs incurred in bringing each product to its present location and condition are accounted for as follows: • Consumable stores and spares, at purchase cost on a first in first out basis. • Concentrate stockpiles at cost of direct materials, power, labour, and a proportion of site overhead. • Ore stockpiles at cost of direct material, power, labour contractor charges and a proportion of site overhead. FinanCial assets Classification The Group classifies its financial assets in the following measurement categories: those to be measured subsequently at fair value (either through the Statement of Other Comprehensive Income “OCI” or through profit or loss; and those to be measured at amortised cost. • • • 80 Griffin MininG LiMitednotes to the FinanCial statements FinanCial assets (continued) The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flows. For assets measured at fair value, gains and losses will be recorded either in profit or loss or in OCI. For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income (“FVOCI”). The Group reclassifies debt investments when and only when its business model for managing those assets changes. Classification of financial assets at amortised cost The Group classifies its financial assets as at amortised cost only if both of the following criteria are met: • • the asset is held within a business model whose objective is to collect the contractual cash flows; and the contractual terms give rise to cash flows that are solely payments of principal and interest. Recognition and derecognition Regular purchases and sales of financial assets are recognised on trade date (that is, the date on which the Group commits to purchase or sell the asset). Financial assets are derecognised when the rights to receive cash flows from the financial assets have expired or have been transferred and the Group has transferred substantially all the risks and rewards of ownership. Measurement At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVPL are expensed in profit or loss. Impairment The Group assesses, on a forward-looking basis, the expected credit losses associated with its debt instruments carried at amortised cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from initial recognition of the receivables, see note 16 for further details. Assets carried at amortised cost For loans and receivables, the amount of a loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that had not been incurred), discounted at the financial asset’s original effective interest rate. The carrying amount of the asset will be reduced and the amount of the loss will be recognised in profit or loss. FinanCial liabilities The Group’s financial liabilities include bank loans, trade and other payables, which are measured at amortised cost using the effective interest rate method. On initial recognition financial liabilities are recognised at fair value net of transaction costs. Financial liabilities are recognised when the Group becomes a party to the contractual agreements of the instrument. All interest related charges and, if applicable, changes in an instrument’s fair value that are reported in profit or loss are included in the income statement line items “finance costs” or “finance income.” 81 RepoRt and accounts 2023notes to the FinanCial statements Foreign CurrenCy transaCtions The financial statements have been prepared in United States dollars equating to the local currency of Bermuda. Whilst registered in Bermuda the Company, together with its subsidiaries and associates, operate in China, the United Kingdom, Hong Kong and Australia. The functional currency of the parent company is US dollars. The functional currency of Hebei Hua Ao is the Renminbi. Foreign currency transactions by Group companies are recorded in their functional currencies at the exchange rate ruling at the date of the transaction. Monetary assets and liabilities have been translated at rates in effect at the statement of financial position date. Any realised or unrealised exchange adjustments have been charged or credited to profit or loss. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction. Non-monetary items measured at fair value are translated using the exchange rates at the date when the fair value was determined. On consolidation the financial statements of overseas subsidiary undertakings are translated into the presentation currency of the Group at the rate of exchange ruling at the reporting date and income statement items are translated at the average rate for the year. The exchange difference arising on the retranslation of opening net assets is recognised in other comprehensive income and accumulated in the foreign exchange reserve. All other translation differences are taken to profit or loss. equity Equity comprises the following: • “Share capital” represents the nominal value of equity shares. • “Share premium” represents the excess over nominal value of the fair value of consideration received for equity shares, net of expenses of the share issue. • “Contributing surplus” is a statutory reserve for the maintenance of capital under Bermuda company law and was created on a reduction in the par value of the Company’s ordinary shares on 15 March 2001. • “Share based payments” represents equity-settled share-based remuneration such as shares issued under a share incentive scheme subject to clawback and share options subject to exercise. • “Foreign exchange reserve” represents the differences arising from translation of investments in overseas subsidiaries. • “Chinese statutory re-investment reserve” represents a statutory retained earnings reserve under PRC law for future investment by Hebei Hua Ao. • “Other reserve on acquisition of non controlling interests” represents the excess of the purchase price paid to acquire non controlling interest rights over the non controlling interests in subsidiary companies. • “Profit and loss reserve” represents retained profits and losses. • “Shares held in treasury” represents ordinary shares in the Company Shares bought in at cost of purchase. Non-controlling interests are determined by reference to the underlying agreements, with the allocation of the purchase consideration on acquisition of non-controlling interests and extension of the Hebei Hua Ao business licence between that capitalised to mineral interests and that charged to reserves by reference to the impact of future cash flows. Following the acquisition of Griffin’s Chinese partner’s equity interests in the Hebei Hua Ao Joint Venture in 2012 and a reappraisal of the arrangements with the Chinese partners, the relationship with them is now in the nature of a service provider facilitating Hebei Hua Ao’s operations in China rather than that of non-controlling interests. In line with this arrangement an annual service charge is paid to the Chinese partners, however, due to the potential variables the Directors are unable to estimate what this will be in any future year. 82 Griffin MininG LiMitednotes to the FinanCial statements equity settled share based payments All goods and services received in exchange for the grant of any share-based remuneration are measured at their fair values. Fair values of services are indirectly determined by reference to the fair value of the shares or share options awarded. Their value is appraised at the share issue or option grant date and excludes the impact of non-market vesting conditions (for example, production upgrades). All share-based remuneration is ultimately recognised as an expense in profit or loss with a corresponding credit to “Share based payments” in the statement of financial position. If vesting periods or other non-market vesting conditions apply, the expense is allocated over the vesting period, based on the best available estimate of the number of share options expected to vest. In the case of shares issued subject to clawback, the expense is allocated over the period from issue to end of the clawback period with an initial credit to share capital and balancing credit to share based payments. At the end of the clawback period the allocation to share based payments is released to share premium. Estimates are subsequently revised if there is any indication that the number of share options expected to vest differs from previous estimates, or if any shares granted under share incentive schemes are to be clawed back. Any cumulative adjustment prior to vesting is recognised in the current period. Upon exercise of share options, the proceeds received net of attributable transaction costs are credited to share capital. For the financial year ended 31 December 2023 the total expense recognised in profit or loss arising from share based transactions was $3,019,000 (2022: Nil). signiFiCant judgements and estimates In formulating accounting policies, the directors are required to apply their judgement, and where necessary engage professional advisors, with regard to the following significant areas: Judgements In assessing potential impairment adjustments and depreciation on a unit of production basis, management have assumed that indicated as well as measured mineral resources will be recovered from Zones II, III, V and VIII at Caijiaying as good conversion from inferred to indicated and indicated to measured has been achieved historically. It is further assumed that all necessary permits will be obtained. In this regard, and in order to comply with amended PRC corporate law, the Company is required to convert Hebei Hua Ao from a limited liability joint venture with a business licence that expires in 2037, to an equity limited liability company with an indefinite term so that its business licence will be renewed without significant cost by 31 December 2024. Impairment review assumptions, exploration interests (note 13). Impairments are assessed by reference to exploration results carried out in an area of interest. Where such exploration indicates that there are no indications of mineralisation within the area of interest, provision is made for impairment in value. Non-impairment of assets is conditional upon continued exploration licences and permits which the directors consider will be maintained or obtained as appropriate. Under the terms of an agreement dated 21 May 2012, Griffin’s Chinese Partners are obliged to provide various services to facilitate Hebei Hua Ao’s operations in China and as such the amounts payable of $3,903,000 (2022 $2,399,000) are included in net operating costs rather than attributable to non-controlling interests. Likewise, the amounts due at 31 December 2023 of $4,697,000 (2022: $3,237,000) are included in other payables rather than due to non-controlling interests within equity within the Consolidated Statement of Financial Position. 83 RepoRt and accounts 2023notes to the FinanCial statements signiFiCant judgements and estimates (continued) Estimates Impairment review assumptions, property, plant and equipment (note 12). Impairments are assessed by comparison of the cash generating unit’s (the Caijiaying Mine) carrying amounts against the value of future discounted cash flows expected to be derived from this cash generating unit. The value of the cash flows are impacted by estimates of: • future prices of the commodities extracted. Estimates were made as at the balance sheet date and do not include changes in future price estimates. • the expected tonnes and grade of ore mined. Management has assumed forecast production of circa 1.5 million tonnes per annum up to 1.6 million tonnes per annum as set out in the life of mine plan. No alterations to existing processing facilities are required to facilitate the increase in production. • future zinc treatment costs. • future operating and capital expenditure. • discount rates. Based on these estimates, the directors have determined that the Group requires the market price of zinc to be above $2,475 on an ongoing basis per tonne with gold, silver and lead prices remaining at current prevailing levels, to avoid an impairment charge. It is also conditional upon mining licences continuing and permits being granted, which the directors consider will be maintained or obtained as appropriate. mine Closure Costs Provisions for mine closure and rehabilitation costs have been made in accordance with the laws and regulations of the PRC and as set out in the Hebei Hua Ao Mine Ecological Restoration Treatment and Land Reclamation Scheme (“the Scheme”) as approved by the Ministry of Natural Resources of the PRC. This Scheme provides for a mine life of 40.11 years from January 2019 to February 2059. The Scheme incorporates a rehabilitation plan for “Mine Geological Environment Recovery” with an estimated cost of RMB 65,619,400 ($9,265,000), and “Land Rehabilitation” with an estimated cost of RMB 54,566,100 ($7,704,000). These amounts have been discounted over the deemed Life of Mine at a discount rate of 2.88%, being the PRC 36 year state bond rate. The directors continually monitor the basis on which their judgements are formulated. Where required they will make amendments to these judgements. Where judgements and estimates are amended between accounting periods, full disclosure of the financial implications are given within the relevant notes to the Group financial statements. Cash and Cash equivalents Cash and cash equivalents comprise cash on hand and demand deposits, together with other short-term, highly liquid investments that are readily convertible into known amounts of cash and which are subject to an insignificant risk of changes in value. Money Market deposits are measured at fair value with movements in fair value recognised in the income statement. The fair value of Money Market funds are based on their quoted market price and valued using level 1 methodology. dividends Dividend distributions payable to equity shareholders are recognised and included in “other short term financial liabilities” when the dividends are declared and authorised by the Board meeting prior to the reporting date, but not distributed prior to the end of the reporting period. 84 Griffin MininG LiMitednotes to the FinanCial statements taxation Current tax is the tax currently payable based on taxable profit for the year. Deferred income taxes are calculated using the liability method on temporary differences. Deferred tax is generally provided on the difference between the carrying amounts of assets and liabilities and their tax bases. However, deferred tax is not provided on the initial recognition of goodwill, nor on the initial recognition of an asset or liability unless the related transaction is a business combination or affects tax or accounting profit. Deferred tax on temporary differences associated with shares in subsidiaries, associates and joint ventures is not provided if reversal of these temporary differences can be controlled by the Group and it is probable that reversal will not occur in the foreseeable future. In addition, tax losses available to be carried forward as well as other income tax credits to the Group are assessed for recognition as deferred tax assets. Deferred tax liabilities are provided in full, with no discounting. Deferred tax assets are recognised to the extent that it is probable that the underlying deductible temporary differences will be able to be offset against future taxable income. Current and deferred tax assets and liabilities are calculated at tax rates that are expected to apply to their respective period of realisation, provided they are enacted or substantively enacted at the reporting date. Changes in deferred tax assets or liabilities are recognised as a component of the tax expense in the income statement, except where they relate to items that are recognised in other comprehensive income (such as the revaluation of land) in which case the related deferred tax is also charged or credited directly to other comprehensive income or equity. segment reporting In identifying its operating segments in note 2, as determined by the Board (the Chief Operating Decision Maker), management generally follows the Group’s service lines, which represent the main products produced by the Group. Management considers there to be only one operating segment being the operations at the Caijiaying Mine based in China with production of zinc concentrate, and lead concentrate with associated precious metals credits. All activities of the Group are reported through management and the executive director to the Board of the Company. The measurement policies the Group uses for Segment reporting under IFRS 8 are the same as those used in its financial statements. Corporate assets which are not directly attributable to the business activities of Caijiaying Mine are not allocated to the Chinese segment but are reviewed in light of operating expenses by the region in which they occur. In the financial years under review, this primarily applies to the Group’s head office and intermediary holding companies within the Group. There have been no changes from prior periods in the measurement methods used to determine reported segment profit or loss. leased assets Leased right of use assets are included within property, plant and equipment and on the inception of the lease at the amount of the corresponding lease liability, adjusted for any lease payments prior to the lease commencement date, plus any direct costs incurred and estimated dismantling, disposal or restoration costs, less any lease incentives received. The right to use assets are depreciated over the economic live of the asset on the same basis as other legally owned assets. lease liabilities Lease liabilities are recognised within non-current and current liabilities. On inception, the lease liability is recognised as the present value of the expected future lease payments, discounted using the Group’s cost of borrowing. Lease payments include fixed payments, variable payments dependent on index or other rate, guarantees, and purchase option payments. 85 RepoRt and accounts 2023notes to the FinanCial statements 2. segmental reporting The Group has one business segment, the Caijiaying Zinc Gold mine in the People’s Republic of China.

Hebei Hua-Ao paid income tax in the PRC at a rate of 25% in 2023 (2022: 25%) based upon the profits calculated under Chinese Generally Accepted Accounting Principles (Chinese “GAAP”). Withholding tax is recognised as a current tax charge when paid. As the Company can control the timing of payments giving rise to withholding tax, deferred tax liabilities for unpaid withholding taxes on unremitted earnings and undistributed dividend payments are recognised using a ‘probable’ threshold (based on the recognition threshold in IAS 12) , and are reflected at the amount expected to be paid to taxation authorities. Unremitted earnings and undistributed dividend payments from the Group’s Chinese mining operation total $127.0m (2022: $128.5m) upon which PRC withholding tax, currently 5%, may be deducted on distribution. 88 Griffin MininG LiMited notes to the FinanCial statements 11. earnings per share The calculation of the basic earnings per share is based upon the earnings attributable to ordinary shareholders divided by the weighted average number of shares in issue during the year. The calculation of diluted earnings per share is based on the basic earnings per share on the assumed conversion of all dilutive options and other dilutive potential ordinary shares. Reconciliation of the earnings and weighted average number of shares used in the calculations are set out below: 2023 Earnings Weighted Per share amount (cents) Average no of shares $000 Earnings $000 2022 Weighted Average no of shares Per share amount (cents) 15,236 189,771,884 8.03 7,704 174,892,894 4.41 Basic earnings per share Basic earnings attributable to ordinary shareholders Dilutive effect of securities Options - 1,234,740 (0.05) - 12,384,576 Diluted earnings per share 15,236 191,006,624 7.98 7,704 187,277,470 12. property, plant and equipment Mineral Mill and interests mobile mine equipment Offices, furniture & equipment (0.30) 4.11 Total At 1 January 2022 Foreign exchange adjustments Transfer re rehabilitation deposit Change in estimate of mine closure costs Additions during the year Disposals Depreciation charge for the year At 31 December 2022 Foreign exchange adjustments Change in estimate of mine closure costs Additions during the year Disposals Depreciation charge for the year At 31 December 2023 At 1 January 2022 Cost Accumulated depreciation Net carrying amount At 31 December 2022 Cost Accumulated depreciation Net carrying amount At 31 December 2023 Cost Accumulated depreciation Net carrying amount $000 $000 $000 $000 220,832 (12,832) (1,012) 130 7,348 - (13,328) 201,138 (2,269) 1,226 16,792 - (21,505) 195,382 285,471 (64,639) 220,832 275,250 (74,112) 201,138 290,077 (94,695) 195,382 53,487 (4,836) - - 13,749 (226) (6,104) 56,070 (929) - 6,056 (521) (6,380) 54,296 97,910 (44,423) 53,487 101,763 (45,693) 56,070 103,479 (49,183) 54,296 977 275,296 8 - - 6 - (17,660) (1,012) 130 21,103 (226) (158) (19,590) 833 258,041 - - - - (3,198) 1,226 22,848 (521) (141) (28,026) 692 250,370 1,544 384,925 (567) (109,629) 977 275,296 1,106 378,119 (273) (120,078) 833 258,041 1,558 395,114 (866) (144,744) 692 250,370 89 RepoRt and accounts 2023 notes to the FinanCial statements 12. property, plant and equipment (continued) Mineral interests comprise the Group’s interest in the Caijiaying ore bodies including costs on acquisition, plus subsequent expenditure on licences, concessions, exploration, appraisal and construction of the Caijiaying mine including expenditure for the initial establishment of access to mineral reserves, commissioning expenditure, and direct overhead expenses prior to commencement of commercial production and together with the end of life restoration costs. Mill and mobile mine equipment include $3,416,000 (2022: $14,007,000) of assets under construction yet to be depreciated. The offices, furniture and equipment disclosed above relates solely to the fixed assets, including leased offices, of Griffin Mining (UK Services) Limited and China Zinc Pty Limited. The Group assesses the carrying value of the mineral interests, mill and mobile mine equipment at least annually, and more frequently in the event of any indications of impairment, by reference to discounted cash flow forecasts of future revenue and expenditure for each Cash Generation Unit. These forecasts are based upon both past and expected future performance, available resources and expectations for future markets. Management determined there were no impairment indicators at 31 December 2023 (2022: nil). However, as best practice and in response to an updated Life of Mine Plan, management have updated the impairment model for latest forecast metal prices, smelter treatment charges , and revisions to mine development costs. In determining any indications of impairment in the carrying value of the Caijiaying Mine the directors have reassessed the net carrying value of property plant and equipment at 31 December 2023 by reference to the estimated mineral resources at Caijiaying that may be extracted by 2050 (2022: 2050). While the current business licence of Hebei Hua Ao expires in 2037, Hebei Hua Ao will be converted to an equity joint venture company with an indefinite life in order to comply with new PRC legislation by 31 December 2024. Accordingly, a Life of Mine Plan has been prepared by the Company that indicates the continued extraction of ore until at least 2050. In estimating the discounted future cash flows from the continuing operations at the Caijiaying mine the following principal assumptions have been made: • Future market prices for zinc of $2,654 (2022: $3,097) per tonne, gold of $2,000 (2022: $1,800) per troy ounce and silver of $23.4 (2022: $22.7) per troy ounce; • Zinc treatment charges of 25% (2022: 30%) of market prices; • Extraction of measured and indicated resources of 41.2 million tonnes (2022: 40.4 million tonnes) to 2050 (2022: 2050) with ore mined and processed of circa 1.5 million tonnes (2022: 1.5 million tonnes) of ore per annum; • Operating costs, recoveries and payables based upon past performance and that budgeted for 2024 and on internal management forecast, for future years; • Capital costs based upon that initially scheduled with sustaining capital based on future scheduling; • Discount rate of 10% (2022: 10%); • Continued maintenance and grant of applicable licences and permits; • No significant impact as a result of climate change, earthquakes or other natural events; and • A Renminbi to US dollar exchange rate of 7 Rmb to $1 (2022: 7 Rmb to $1) Having considered the impact of climate change, the directors consider that there will not be any significant adverse impact on future operations from climate change. Whilst the directors consider the assumptions reasonable, sensitivities have been considered to assess the impact of changes in key assumptions including, forecast metal prices, foreign exchange and discount rates, and have concluded that there were no reasonable possible changes to the key assumptions that could result in an impairment. 90 Griffin MininG LiMitednotes to the FinanCial statements 13. intangible assets - exploration interests China – mineral exploration interests At 1 January 2022 Additions during the year At 31 December 2022 Additions during the year At 31 December 2023 $000 387 20 407 168 575 Intangible assets represent cost on acquisition, plus subsequent expenditure on licences, concessions, exploration, appraisal and development work in respect of regional exploration in China.

An offer was made on 30 December 2022 to option holders for the purchase and cancellation of outstanding options over 19,520,000 shares in the Company (“the Offer”). Acceptances have been received from option holders in respect of options to purchase 17,520,000 shares in the Company which have subsequently been purchased and cancelled, which based on the mid-market price on the Offer date of 76 pence per share have resulted in 10,130,526 new ordinary shares being issued pursuant to the Offer for nil consideration. All amounts are short term. The carrying values of all trade and other payables are considered to be a reasonable approximation of fair value. 95 RepoRt and accounts 2023 notes to the FinanCial statements 28. attributable net asset value per share to total equity per holders oF parent shares The attributable net asset value / total equity per share has been calculated from the consolidated net assets / total equity of the Group at 31 December 2023 of $269,752,000 ($245,465,000 at 31 December 2022) divided by the number of ordinary shares in issue at 31 December 2023 of 192,828,420 (174,892,894 at 31 December 2022). 29. risk management The Group is exposed to a variety of financial risks which result from its operating and investing activities. The Group’s risk management is coordinated by its senior management and executive directors and focuses on actively securing the Group’s cash flows for the foreseeable future. Foreign Currency Risk The majority of the Group’s operational and financial cash flows are denominated in Chinese Renminbi and United States Dollars with Sterling, Hong Kong dollars, and Australian Dollar bank deposits held to cover future local expenditure estimates. Currently the Group does not carry out any significant operations in currencies outside the above. The Group currently does not have a formal foreign currency hedging policy but retains foreign currency to meet future requirements. Management monitors foreign exchange exposure and considers hedging significant foreign currency exposure should the need arise. The conversion of Renminbi into foreign currencies is restricted and subject to the rules and regulations of foreign exchange control promulgated by the government of the People’s Republic of China. Sterling bank deposits translated into United States Dollars at the closing rate are as follows: Short term bank deposits 2023 $000 331 Australian dollar bank deposits translated into United States Dollars at the closing rate are as follows: Short term bank deposits 2023 $000 1,182 Renminbi bank deposits translated into United States Dollars at the closing rate are as follows: Short term bank deposits 2023 $000 20,790 2022 $000 318 2022 $000 1,037 2022 $000 13,993 The following table illustrates the sensitivity of the net results for the year and equity with regards to the Group’s Renminbi deposits and the Renminbi US Dollar exchange rate. It assumes a + / - 10% (2022: 10%) change in the Renminbi exchange rate for the year ended 31 December 2023. These changes are considered to be reasonable based on observation of current market conditions for the year ended 31 December 2023. The sensitivity analysis is based upon the Group’s Renminbi deposits at each reporting date. If the Renminbi had strengthened against the US Dollar by 10% (2022: 10%) this would have had the following impact: Net result for the year and on equity 96 2023 $000 2,310 2022 $000 1,555 Griffin MininG LiMited notes to the FinanCial statements 29. risk management (continued) Foreign Currency Risk (continued) If the Renminbi had weakened against the US Dollar by 10% (2021: 10%) this would have the following impact: Net result for the year and on equity 2023 $000 (1,890) 2022 $000 (1,272) Exposures to foreign exchange rates vary during the year depending on the volume of overseas transactions. Nonetheless, the analysis above is considered to be indicative of the Group’s exposure to currency risk. With relatively small amounts held in Sterling, Australian dollars, and Hong Kong dollars the effect on the net results and equity of changes in Sterling, Australian dollar and Hong Kong exchange rates are not expected to be significant. Foreign currency denominated financial assets and liabilities, translated into US Dollars at the closing rate, are as follows: 2023 Rmb $000 AusD $000 GBP $000 2022 Rmb $000 AusD $000 GBP $000 449 21,157 1,187 609 17,128 1,043 (1,030) (36,295) (24) (1,254) (38,193) (24) (581) (15,138) 1,163 (645) (21,065) 1,019 Financial assets Financial liabilities Short term exposure Interest rate risk The Group’s exposure to the risk of changes in market interest rates relates primarily to the Group’s bank deposits with floating interest rates. The Group currently does not have an interest rate hedging policy. The following table illustrates the sensitivity of the net results for the year and equity to a reasonably possible change in interest rates of + 100% and - 100% (2022: + 100% - 100%), with effect from the beginning of the year. These changes are considered to be reasonable based on observation of current market conditions within which the Group operates. The sensitivity analysis is based upon the Group’s deposits at each balance sheet date: Net result for the year 2023 2022 Plus 100% Minus 100% $000 $000 Plus 100% Minus 100% $000 $000 1,394 (1,394) 369 (369) Fixed and non interest bearing financial assets and liabilities are as follows: 2023 interest rate Fixed Non interest bearing Total 2022 Fixed Non interest bearing interest rate Total $000 $000 $000 $000 $000 $000 Financial assets Cash at bank Rehabilitation deposits Other receivables Total Financial Assets 35,756 - - 35,756 24,251 1,554 490 26,295 60,007 1,554 490 62,051 17,479 - - 17,479 16,659 1,494 374 18,527 34,138 1,494 374 36,006 Lease liabilities Trade and other payables (739) - - (41,414) (739) (41,414) (852) - - (41,910) (852) (41,910) Total Financial Liabilities Net Financial assets / (liabilities) (739) 35,017 (41,414) (15,119) (42,153) 19,898 (852) 16,627 (41,910) (23,383) (42,762) (6,756) 97 RepoRt and accounts 2023 notes to the FinanCial statements 29. risk management (continued) Commodity risk The Group is exposed to the risk of changes in commodity prices and in particular that for zinc, gold and to a lesser extent silver and lead. The Group currently sells its metal concentrate production by way of open auctions in China. The Group did not hedge its metal production in 2023 or in 2022. The following table illustrates the sensitivity of the net results for the year and equity to a reasonably possible change in the market price of zinc of plus 30% and minus 30%, gold of plus 10% and minus 10% and silver of plus 20% and minus 20% (2022: zinc plus 30% and minus 30%, gold plus 10% and minus 10% and silver plus 20% and minus 20%), with effect from the beginning of the year. These changes are considered reasonable based upon observation of current market conditions within which the Group operates. This sensitivity analysis is based upon the Group’s sales in each year: Net result for the year – zinc Net result for year – gold Net result for year – silver Credit risk 2023 Plus $000 Minus $000 2022 Plus $000 Minus $000 23,685 (23,685) 16,169 (16,169) 2,452 (2,452) 1,341 (1,341) 940 (940) 584 (584) Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. The Group is exposed to credit risk from its financing activities, including deposits with banks and financial institutions, foreign exchange transactions and other financial instruments. The Group does not have trade receivables and does not hold collateral as security. Excess funds are placed on money market with counter party premier banks (note 17). Credit risk from balances with banks and financial institutions is managed by the Board. Investment of surplus funds are made only with approved counterparties and within credit limits assigned to each counterparty. Counterparty credit limits are reviewed on a regular basis. The limits are set to minimise the concentration of risks and therefore mitigate financial loss through potential counterparty failure. No material exposure is considered to exist by virtue of the possible non performance of the counterparties to financial instruments. Liquidity risk Prudent liquidity risk management implies maintaining cash, marketable securities and adequate credit facilities to meet financial obligations as they fall due. At 31 December 2023 the Group held cash and cash equivalents (bank deposits) with high credit financial institutions of $60,007,000 (2022: $34,138,000) to meet financial obligations and apart from lease, trade and other payables had no bank loans or similar financial liabilities. Management monitors rolling cash flow forecasts on a weekly basis and keeps under review bank financing facilities at a local and Group level, to ensure sufficient liquidity is maintained to meet future financial obligations. This also includes regular review of metal market prices and foreign currency requirements. Hebei Hua Ao retains rolling bank loan facilities of Rmb150m ($21.4m) renewable on 14 May 2025 and Rmb100m ($14.3m) renewable on 23 May 2024 that have not been drawn down. 30. Capital management and proCedures The Group’s capital management objectives are: • To ensure the Group’s ability to continue as a going concern; • To increase the value of the assets of the Group: and • To enhance shareholder value in the Company and returns to shareholders. The achievement of these objectives is undertaken by developing existing ventures and identifying new ventures for future development. The Company will also undertake other transactions where these are deemed financially beneficial to the Company. 98 Griffin MininG LiMited notes to the FinanCial statements 30. Capital management and proCedures (continued) The directors continue to monitor the capital requirements of the Group by reference to expected future cash flows. Capital for the reporting periods under review is summarised in the consolidated statement of changes in equity. The directors consider the capital of the Group to be the total equity attributable to the equity holders of the parent of $269,752,000 at 31 December 2023. 31. FinanCial instruments The Group does not enter into derivative transactions such as interest rate swaps, forward rate agreements or forward currency contracts. Funds in excess of immediate requirements are placed in US dollar, Chinese Renminbi, Australian Dollar and Sterling short term fixed and floating rate deposits. The Group has overseas subsidiaries operating in China, the United Kingdom, Hong Kong and Australia, whose costs are denominated in local currencies. In the normal course of its operations the Group is exposed to commodity price, foreign currency and interest rate risks. The Group places funds in excess of immediate requirements in US dollar, Chinese Renminbi, Australian Dollar and Sterling deposits with a number of banks to spread currency, interest rate and bank risk. These deposits are kept under regular review to maximise interest receivable and with reference to future expenditure and future currency requirements. Commodity prices are monitored on a regular basis to ensure the Group receives fair value for its products.
