SLR International Corporation (SLR) was retained by SSR Mining Inc.(SSR) to prepare an independent Technical Report Summary (TRS) on the Çöpler Property (the Property or the Project), located in Erzincan Province, Türkiye. The Property is owned and operated by Anagold Madencilik Sanayi ve Ticaret Anonim Şirketi (Anagold). SSR controls 80% of the shares of Anagold, Lidya Madencilik Sanayi ve Ticaret A.Ş. (Lidya), controls 18.5%, and a bank wholly owned by Çalık Holdings A.Ş., holds the remaining 1.5%.

The purpose of this TRS is to disclose the results of the Mineral Resource and Mineral Reserve estimates for the Property with an effective date of October 31, 2023. This TRS conforms to the United States Securities and Exchange Commission’s (SEC) Modernized Property Disclosure Requirements for Mining Registrants as described in Subpart 229.1300 of Regulation S-K, Disclosure by Registrants Engaged in Mining Operations (S-K 1300) and Item 601 (b)(96) Technical Report Summary. SLR visited the property on August 29-31, 2023. SLR, RSC Consulting Ltd (RSC), WSP USA Inc. (WSP) and Ausenco Pty Services Limited (Ausenco) are the Qualified Persons (QPs) as required by S-K 1300 for purposes of this TRS.

SSR is a gold mining company with four producing assets located in the USA, Türkiye, Canada, and Argentina, and with development and exploration assets in the USA, Türkiye and Canada. SSR is listed on the NASDAQ (NASDAQ: SSRM), the Toronto Stock Exchange (TSX: SSRM), and the Australian Stock Exchange (ASX: SSR).

The Property consists of several mining licenses covering Mineral Resources on the Çöpler mine, Greater Çakmaktepe (Çakmaktepe and Çakmaktepe Extension (Ext.) - previously referred to as Ardich), and Bayramdere deposits, Mineral Reserves on the Çöpler and Greater Çakmaktepe deposits, oxide and sulfide processing facilities, and supporting infrastructure.

This report is an update of SSR's prior Technical Report Summary for the Property, dated as of September 29, 2022.

The QPs offer the following conclusions by area.

1-2

The QP is of the opinion that with consideration of the recommendations summarized in Sections 1 and 23 of this TRS, any issues relating to all relevant technical and economic factors likely to influence the prospect of economic extraction can be resolved with further work.

An after-tax Cash Flow Projection has been generated from the Life of Mine production schedule and capital and operating cost estimates and is summarized in Table 1-2. A summary of the key criteria is provided below. The complete cash flow is presented in Section 27.0 Appendix. The analysis is based on Q4 2023 real US dollar basis with no escalation.

1-9

In Türkiye, the standard income tax rate is 25% but some of the site’s income streams qualify for a reduced rate, thus the effective LOM income tax rate is 24.5%.

For tax purposes, a 10 year double declining balance methodology is used for all new and replacement capital starting in 2024 totaling $536 million. For the existing depreciation balance of $290 million as of Q3 2023, a combination of accelerated, straight line, and unit of production depreciation methods is used as modeled by the SSR tax group. All remaining depreciation at the end of the mine life is written off in the last year of production.

Investment incentive certificates (IIC) are available for investments that promote economic development. IIC’s can be classified as strategic in specific circumstances, thereby providing additional incentives. An IIC generates credits that offset corporate income taxes generated by the investment. In this analysis, income tax credits totaling 29% over the LOM were applied to the income tax payable estimate, in 90% credits applied in 2024 and 2025 and 80% credits applied in 2026 to 2028, as modeled by the SSR tax group.

This analysis assumes the annual operating and capital cost are subject to value-added tax (VAT) in Türkiye. VAT is levied at 4% of all operating and capital costs (less labor costs) starting July 2023, and the Project is eligible for the Turkish exemptions for mining projects and mining equipment purchases. VAT payments are expected to end in 2025.

Import duties are not included in the capital cost estimate for mining related imported equipment because they are exempted in the IICs.

1-10

Under Turkish Mining Law, the royalty rate for precious metals is variable and tied to metal prices. The Çöpler Project is subject to a mineral production royalty which is based on a sliding scale to gold price and is payable to the Turkish government.

Table 1-1 details the current prescribed royalty rates applicable to POX, heap leach and G-L production (revised September 2020). The royalties are calculated on total revenue with deductions allowed for processing and haulage costs of ore. Royalty rates are reduced by 40% for ore processed in country, as an incentive to process ore locally.

Table 1-1: Gold Royalty Rates

The Çöpler Project effective LOM royalty rate based on the metal price assumptions and applicable deductions is approximately 8.4%.

Other than the royalty payments, there are no other known back-in rights, payments, or other agreements and encumbrances to which the Project is subject.

Considering the Çöpler Project on a stand-alone basis, the undiscounted after-tax cash flow totals $2,368 million over the mine life. The after-tax Net Present Value (NPV) at a 5% discount rate (midpoint with November 1, 2023 as time zero) is $1,643 million, as shown in Table 1-2. An Internal Rate of Return (IRR) metric is not reported as the operation is cash positive in each year of the mine plan until closure.

1-11

Table 1-2: After-Tax Cash Flow Summary

Notes:

The World Gold Council Adjusted Operating Cost (AOC) is US$965/oz Au. The mine life capital unit cost, including sustaining and closure/reclamation, is US$38/oz, for an All in Sustaining Cost (AISC) of US$1,003/oz Au. The average annual gold production during operation is 281,000 ounces per year over ROM operations.

Project risks can be identified in both economic and non-economic terms. Key economic risks were examined by running cash flow sensitivities:

1-12

After-tax IRR sensitivity over the base case has been calculated for -20% to +20% variations for head grade, recovery (only -20% to +15% variation), and gold price, and -15% to +15% variations for operating and capital costs. The Project is most sensitive to changes in head grade, metallurgical recovery, and metal price (usually with same magnitude of impact) followed by operating cost and finally capital costs.

The Project is serviced by road and rail networks. The mine is accessed from the main paved highway between Erzincan and Kemaliye. The Project area is in the Eastern Anatolia geographical district of Türkiye. Mining operations are conducted year-round. The climate is typically continental with cold wet, winters and hot dry, summers.

Anagold holds the exclusive right to engage in mining activities within the Çöpler project area. Anagold holds six granted licenses covering a combined area of approximately 16,600 ha. Mineral title is held in the name of Anagold. Kartaltepe holds six licenses covering approximately 7,250 ha. The total near-mine tenement package is approximately 23,850 ha. Anagold currently holds sufficient surface rights to allow continued operation of the mining operation in the Reserve Case.

The Çöpler region has been subject to gold and silver mining dating back at least to Roman times. The Turkish Geological Survey (MTA) carried out regional exploration work in the early1960s that was predominately confined to geological mapping. In 1964, a local Turkish company started mining for manganese, continuing through until closing in 1973. Unimangan Manganez San A.Ş. (Unimangan) acquired the property in January 1979 and re-started manganese production, continuing until 1992. In 1998, Anatolia Minerals Development Ltd (Anatolia) identified several porphyry-style gold–copper prospects in east central Türkiye and applied for exploration licenses for these prospects. During this work, Anatolia identified a prospect in the Çöpler basin. This prospect and the supporting work were the basis for a joint venture agreement for exploration with Rio Tinto and Anatolia and in January 2004, Anatolia acquired the interests of Rio Tinto and Unimangan.

In August 2009, a joint venture agreement between Anatolia and Lidya was executed.

In February 2011, Anatolia merged with Avoca Resources Limited, an Australian company, to become Alacer Gold Corp. (Alacer). In September 2020, Alacer merged with SSR.

Technical Reports have been prepared on the Project in accordance with NI 43-101 Standards for Disclosure for Mineral Projects since 2003. In 2022, a Technical Report Summary was prepared, in accordance with S-K 1300, that presented an Initial Assessment for a copper recovery circuit.

The Çöpler Project, including Çöpler, Greater Çakmaktepe, and Bayramdere deposits, is within the Tethyan mineral belt, a terrane stretching from Indo-China to Europe through Eurasia that contains economically significant gold, copper, and base metal deposits.

The Çöpler deposit is centred on composite diorite to monzonite porphyry stocks that are part of the Eocene Çöpler Kabataş magmatic complex. The magmatic rocks have intruded into both the Keban and Munzur Formations. The mineralisation is considered to be related to fluids associated with diorite intrusions at depth.

Three types of mineralization are prevalent at the deposits; 1) intermediate sulfidation epithermal gold 2) replacement gold and 3) skarn gold. At Ҫӧpler there is also evidence of an earlier low grade porphyry copper-gold system.

The Greater Çakmaktepe area mainly comprises Palaeozoic metamorphic rocks and marble belonging to the Keban Formation and Mesozoic platform carbonate such as the Munzur Formation limestone. All these units are tectonically overlain by ophiolitic mélange rocks. Mineralisation similar to Çöpler is also thought to be the result of intrusive activity that generated suitable conditions for mineralisation of ophiolite, limestone, and hornfels lithologies. The mineralisation is controlled by a complex system of structural fluid pathways and traps controlled by lithological contacts, in typical replacement-style processes.

The Bayramdere deposit is an oxide gold and copper deposit with similar geological and mineralisation characteristics to Greater Çakmaktepe deposits. The Bayramdere deposit is structurally controlled, displaying a replacement gold (minor copper, minor silver) mineralisation style. The deposit is dominantly represented by near-surface oxide mineralisation, primarily associated with iron-rich gossan.

Core (Diamond Drilling-DD) and RC drilling on the Property is the principal method of exploration and delineation of gold mineralization after initial targeting using soil sampling and geophysical surveys.

As of the effective date of this TRS, SSR and its predecessor companies have completed 725,840 m of drilling in 4,834 drillholes in the property.

Mineral Resources have been classified in accordance with the definitions for Mineral Resources in S-K 1300. RSC Consulting Ltd. (RSC) has prepared, reviewed, and accepted the Mineral Resource estimates. The Mineral Resource estimates are based on block model values developed from assays on the mineralized properties.

The Mineral Resource estimates were completed using conventional block modelling approach in Seequent’s Leapfrog Geo (Leapfrog Geo) software.

Estimates were validated using standard industry techniques including statistical comparisons with composite samples and parallel nearest neighbor (NN) estimates, swath plots, and visual reviews in cross-section and plan. A visual review comparing blocks to drill holes was completed after the block modelling work was performed to ensure general lithologic and analytical conformance and was peer reviewed prior to finalization. Mineral Resources (SSR ownership 80% only) have been summarised based on deposit, resource classification and processing methodology.

Mineral Reserve estimates as prepared by SSR, and reviewed and accepted by the SLR QP, have been classified in accordance with the definitions for Mineral Reserves in S-K 1300.

The Mineral Reserves were developed based on mine planning work completed in 2023 and estimated based on an October 31, 2023, topography surface. The total Mineral Reserve for the Çöpler Project is estimated to be approximately 67.4 Mt at an average grade of 2.32 g/t Au, totaling 5.1 Moz of contained gold, and SSR’s portion is 53.9 Mt at an average grade of 2.32 g/t Au, totaling 4.1 Moz of contained gold. SSR’s portion of the Mineral Reserves for both Çöpler and Greater Çakmaktepe is 80%.

Average oxide gold recoveries are 61% and average sulfide gold recoveries range from 81% to 91% for the Mineral Reserves.

The Mineral Reserve estimates have an effective date of October 31, 2023. SSR’s 80% attributable portion of the Mineral Reserves have been summarized by pit area and reserve classification category in Table 1-4.

The mining method is an open pit method, which includes:

Open pit mining at the Çöpler project is performed by a mining contractor and managed by Anagold. The mining contractor, who has been with the Project since it started in 2011 provides equipment operators, maintenance personnel, line supervisors, equipment, and ancillary facilities required for the mining operation. Anagold provides management, technical, mine planning, engineering, and grade control.

Anagold currently operates a sulfide process plant and an oxide heap leach facility. Costs are based on the actual operational costs and the Project budget assumptions.

Pit designs for the Çöpler pit were reviewed and updated in 2023. The Greater Çakmaktepe pit designs were prepared in 2022 and 2023. Production schedules and costs have been updated based on recent site performance and updated contracts.

Processing and recovery methods are determined by sulfur content in the ore. Oxide ore (<2% sulfur) is processed via a three-stage crushing circuit followed by agglomeration prior to being stacked on a heap leach. The pregnant leach solution from the heap leach is processed through carbon adsorption, desorption and refining to produce doré bars. The ore contains cyanide soluble copper that consumes cyanide increasing operating cost. Copper cyanide in the leach solutions is treated in a sulfidation, acidification, recycling, and thickening (SART) plant which precipitates the copper as copper sulfide and regenerates sodium cyanide, which is recycled into the leach solutions.

The sulfide processing plant (>2% sulfur ore) comprises a POX sulfide processing plant, which began operation in 2018 and comprises crushing, grinding, acidulation, pressure oxidation, iron / arsenic precipitation, gold cyanide leaching, carbon adsorption, carbon desorption and refining. The original sulfide circuit, before the addition of flotation, demonstrated additional capacity in the crushing, grinding and autoclave circuits. A sulfide flotation circuit was added to process a portion of the grinding thickener feed to generate a sulfide concentrate that is added to the POX feed to control the sulfide feed concentration. The flotation tailings containing carbonates bypass the acidulation and sulfide oxidation portion of the plant and report directly to the cyanide leach feed for recovery of any cyanide soluble gold. Sulfide flotation allows the POX autoclaves to maximize throughput and sulfide sulfur oxidation capacity and increase overall plant throughput. Tailings are thickened and routed to the TSF.

A new processing facility is being considered at Çöpler. The proposed process is intended to treat oxide and low sulfur (< 2% sulfur) ores from the Çakmaktepe Ext. open pit and is a conventional grind leach process. The grind leach process plant is designed to treat 248 tph of ore during 8,059 hours per year of operation or 92% availability for a total of 2 Mtpa. The operating availability of the crushing section will be 70%. The process will comprise primary jaw crushing, SAG mill and ball mill grinding closed by hydrocyclones, carbon-in-leach (CIL) cyanidation, carbon elution, electrowinning, and refining of electrowinning precipitate to produce a final precious metal (doré) product.

1-21

Existing Infrastructure

The existing facility infrastructure supports the mine and process areas of oxide heap leach and sulfide plant. The existing infrastructure, and the tailings storage and heap leach pad area once the planned expansions for each are complete, will be sufficient for the current Mineral Reserves. The infrastructure for flotation circuit at the sulfide plant commissioned in 2021 was supported by the existing facility infrastructure with some components modified to meet the addition of the flotation circuit.

The current leach pad consists of four phases with an estimated capacity of 63 Mt of oxide ore heap and a nominal maximum heap height of 100 m above the pad liner. An additional phase 5, with a capacity of 13.8 Mt will be added to accommodate some of the oxide to be mined from Greater Çakmaktepe.

The current TSF is being developed and constructed in stages. The development of TSF-1 includes seven phases. TSF 1 phase 4 construction has been completed and approval for use was granted in November 2023 by the Ministry of Environment, Urbanisation and Climate Change (MoEUCC). TSF-1 is permitted through phase 5, and a design application amendment to provide MoEUCC approval for phases 6 and 7 is planned. Ongoing work in ensuring sufficient long-term capacity for storage of tailings has been undertaken. Studies by Anagold have determined that the effect of the addition of the flotation circuit to the sulfide plant would result in an increase in the solids content and improvement in the final settled density based on an increase in the rate of tailings consolidation. Currently TSF-1 holds 13.3 Mt of tailings as of the Effective Date of this report and has a design capacity of to 65.8 Mt.

Planned Future Infrastructure

Anagold is investigating TSF sites with the potential to increase tailings capacity beyond the currently 65.5 Mt design capacity pending environmental, social, and community relations engagements. WSP is currently working with Anagold to develop PFS-level TSF design options including a scenario to complete a lift in TSF-1 from 1,275 MASL to 1,280 MASL which would provide an expected 77 Mt of capacity which be adequate to contain the expected 73.3 Mt of tailings anticipated by the end of the LOM.

The markets for gold and silver doré are readily accessed and available to gold producers. Currently, 100% of the gold and silver is delivered to the Istanbul Gold Refinery. Copper precipitate is currently produced from the SART plant and sold into local markets in Türkiye.

The Çöpler mining and processing operations have a well-established and effective environmental, social, and permitting management program (10+ years). Site staff is knowledgeable and experienced in site and regulatory requirements and supported by corporate technical and ESG personnel as well as outside (Turkey and International) technical experts. Budgets are reasonable and there were no critical path permitting items noted that would limit production and Reserve/Resource development. A reclamation/closure plan and estimates to perform this activity are in place. The budgets and staffing to perform required programs are adequate and indicative of site activities, requirements, and responsibilities.

Anagold and Kartaltepe currently hold sufficient surface rights to support the Base Case, which includes oxide heap leach mining operations, sulfide processing, and tailings disposal.

The following subsection has been modified from OreWin (2022).

At present, there are no known environmental liabilities to which the Project is subject. Further discussion on environmental matters with respect to the Project is provided in Section Environmental Studies, Permitting, and Social Plans, Negotiations, or Agreements with Local Individuals or Groups.

Under Turkish Mining Law, the royalty rate for precious metals is variable and tied to metal prices. The Çöpler project is subject to a mineral production royalty that is based on a sliding scale to gold price and is payable to the Turkish government. In September 2020 a presidential decree was issued, increasing the prescribed royalty rates by 25%.

Table 3-2 details the relevant prescribed royalty rates along with the revised rates following the September 2020 presidential decree. The royalties are calculated on total revenue with deductions allowed for processing and haulage costs of ore. Revenue from by-products (silver and copper) is included in the total revenue used for royalty calculations.

The royalty rates outlined in Table 3-2 apply to gold production from heap leaching. Royalty rates are reduced by 40% for ore processed in country, as an incentive to process ore locally. As the Çöpler Project produces its gold doré on site, the Çöpler Project is eligible for a 40% reduction to the royalty rate for gold produced from pressure oxidation (POX) processing.

Table 3-2: Gold Royalty Rates

3-8

The Çöpler Project effective life-of-mine (LOM) royalty rate based on the financial model metal price assumptions and applicable deductions is approximately 8.4%.

Other than the royalty payments, there are no other known back-in rights, payments, or other agreements and encumbrances to which the Project is subject.

The following subsections have been modified from OreWin (2022).

The EIA permitting for the Çöpler Mine oxide ore was completed in April 2008 with the issuance of an EIA positive certificate. All the necessary operation permits have already been obtained for the oxide inventory, as follows:

The EIA permitting process for the Sulfide Expansion Project was commenced on April 7, 2014, and completed with the receipt of an ’EIA Positive Statement‘ on December 24, 2014. In addition to an EIA approval, other permits required for the Sulfide Expansion Project involved an expanded workplace opening permit, additional operating permits, and land acquisition permits for forest areas and pasture lands.

Additional EIA studies conducted and environmental permits received for the Çöpler and Greater Çakmaktepe mine since the start of the gold mining operations are as follows:

The following subsections have been extracted from OreWin (2022).

The Çöpler project is accessed from the main paved highway between Erzincan and Kemaliye, crossing the Karasu River and passing by the village of İliç. From İliç there is an additional 4.5 km of road to reach the entrance to the Çöpler mine site.

The Ankara to Erzincan railway line, operated by the Turkish State Railway Company (TCDD), runs parallel to the south bank of the Karasu River and passes within two kilometres north of the Project at a point between the train stations at İliç and Bağıştaş. The railway line connects the site with Ankara and the west as well as with seaports to the north on the Black Sea, and to the south on the Mediterranean Sea. Overnight passenger sleeper cars are available between Erzincan and Ankara.

The reservoirs of the Bağıştaş I and II hydro-electric power plants (HEPP) are 350 m and 1,800 m away from the Çöpler mine site, respectively. The embankment of Bağıştaş I Dam originally covered a portion of the existing highway, railroad, and railroad station until these were relocated before dam construction was completed. Construction routes for the railroad and highway were located between the new Çöpler village and the Çöpler mine site. The bridge on the north-east side of İliç was relocated to further east of the embankment.

There are regular commercial airline flights from Istanbul and Ankara to the regional cities of Erzincan, Erzurum, Malatya, Elazığ, and Sivas. Driving from the regional cities to the Project site takes between two to four hours on paved highways. Driving from Ankara to the site takes approximately eight hours.

Mining operations are conducted year-round. The climate is typically continental with cold wet winters and hot dry summers. In winter, the night-time temperature can drop to –25°C although the average is usually a few degrees below freezing. The July temperature frequently exceeds +40°C but the climate is usually pleasantly warm outside of these extremes. The average monthly temperature ranges from +3.7°C for the coldest month of January to +23.9°C for August, the warmest month.

Most precipitation occurs in the winter and spring. Monthly average rainfall values are shown in Figure 4-1. The average annual rainfall for the site is 384.3 mm. Snowfall is common during the period mid-November through February, but with little, if any, accumulation. Snow depth assessments are based on the Divriği meteorological weather station, located 41 km west of the Project area, which shows maximum snow-pack depths at approximately 200 mm for 1985.

The frost depth is less than 0.3 m, based on local information, with 0.5 m selected as the design frost depth limit.

The maximum wind speed recorded at the Divriği weather station in 2004 ranges from 15 m/s to 25 m/s, with variable directions mainly from the north, south, and east.

The district of İliç has a population of approximately 3,800 inhabitants and is located approximately six kilometres east of the current Çöpler open pit. The district has a hospital, schools, municipal offices, a fire station, a police station, and a Gendarmerie post. The primary economic activity in the region is sheep herding for wool, meat, and dairy products. Other agricultural activities include bee keeping for honey production and, some wheat farming along the Karasu River. Additionally, there is some light manufacturing and grain milling performed in İliç.

The workforce for the Anagold exploration programs has primarily included residents drawn from the local communities of Çöpler, İliç, and Sabırlı.

Turkish telecommunications are up to European standards. High-speed, fibre-optic internet access is available at the mine site.

Initially, electrical power at 380 V and 50 Hz was available in İliç and at the mine site. This was upgraded to support the Project by the construction of a 40 km long 154 kV power line from the sub-station at Divriği to the mine site. The power supply was further upgraded when the hydroelectric dam near the mine site was commissioned. Çöpler is now connected to the national grid by a 6 km, 154 kV powerline from the Bağıştaş sub-station.

Sufficient local fresh water supply exists to support the mining and processing operations. Ground water resources include seven production wells with a 25,728 m³/day extraction permit. Further information on project infrastructure is included in Section 15. Section 17.3 contains additional data on the Project social setting.

The Çöpler project is located in a roughly east–west oriented valley at altitudes ranging from 1,100 MASL to 1,300 MASL. The valley is surrounded by limestone mountains that rise to more than 2,500 MASL on the north and south sides of the Project area. These mountains are at the western end of the Munzur range, which rises to more than 3,300 MASL between Ovacık and Kemah.

The region is sparsely vegetated, predominantly with semi-arid brush and scrub trees including dwarf oaks and junipers.

The following are the site data developed during previous studies for the design of the Project:

The following subsections have been modified from OreWin (2022).

The region around the Project has been subject to gold and silver mining that appears to date back at least the ancient Roman times. A copper-rich slag pile of approximately 2,500 t is located at the western edge of the district and is believed to be waste from ancient production. Although the district contains copper mineralization, there appears to have been little production targeting copper. There are several additional minor slag piles scattered around the Project area thought to be from ancient, small-scale gold and by-product copper production.

The Turkish Geological Survey (MTA) carried out regional exploration work in the early 1960s that was predominately confined to geological mapping. In 1964, a local Turkish company started mining for manganese, continuing until closing in 1973 and producing approximately 7,300 t of manganese ore during its active life. Unimangan Manganez San A.Ş. (Unimangan) acquired the property in January 1979 and re-started manganese production, producing one to five thousand tonnes per annum (ktpa) of ore until ceasing operations in 1992.

In 1998, Anatolia Minerals Development Ltd (Anatolia) identified several porphyry-style gold-copper prospects in east central Türkiye and applied for exploration licenses for these prospects. This work was based upon the earlier work by MTA in the 1960s. During this effort, Anatolia delineated a prospect in the Çöpler basin formed by an altered and mineralized granodiorite, intruded metasediment, and limestone. This prospect and the supporting work were the basis for a joint venture agreement for exploration with Rio Tinto.

During the period of the joint venture, exploration drilling of the Çöpler Deposit was completed and a Mineral Resource estimate was developed with three mineralized zones: Main, Manganese, and Marble. In January 2004, Anatolia acquired sole control over the Project and maintained exclusivity until 2009, at which time a joint venture with Lidya was executed.

In February 2011, Anatolia merged with Avoca Resources Limited to form Alacer Gold Corp. (Alacer). In September 2020, Alacer merged with SSR.

The Çöpler property area is currently owned and operated by Anagold, which is held by SSR (80%), Lidya (18.5%), and a bank wholly owned by Çalık Holdings A.Ş. (1.5%).

The Greater Çakmaktepe property area is owned by Kartaltepe, which is held by SSR (80%) and Lidya (20%).

Exploration of the Çöpler Deposit has been conducted by Anagold and its predecessors since September 1998. Work completed has included the following:

5-1

The principal exploration technique used at the Project has been RC and DD drilling, conducted in multiple campaigns since 2000. Initially, exploration was directed at evaluating the economic potential of the near-surface oxide mineralization for the recovery of gold by either heap leaching or conventional milling techniques.

In 2013, drilling occurred primarily in the western portion of the Main Zone and on the northern edge of the Çöpler Deposit. Drilling during 2014 focused on verification of existing drilling results through a twin-hole program. Drilling in 2015 provided data coverage at depth in the Manganese Zone, infill drilling in the Main Zone, and testing of low-sulfur mineralization below the oxidation boundary.

Drilling continues to better define both the oxide and sulfide portions of the Çöpler Deposit.

Türkiye is predominantly situated on the Anatolian Plate which is bounded by the Eurasian plate to the north, the Arabian Plate to the southeast, the African Plate to the south, and the Aegean Plate to the west. Due to the convergence between the Eurasian and Arabian plates, the Anatolian Plate is displaced westward along two major strike-slip fault zones: the North Anatolian Fault and the East Anatolian Fault. The North Anatolian Fault has a right-lateral displacement and forms the boundary between the Anatolian Plate and the Eurasian Plate to the north. The East Anatolian Fault has left-lateral displacement and forms the boundary between the Anatolian Fault and the Arabian Plate to the southeast. The region is also influenced by the subduction of the Neo-Tethys oceanic plate which led to arc and back arc magmatism during the Late Cretaceous and Middle Miocene era and continuing to the present.

A regional geology plan is presented in Figure 6-1.

The Çöpler Project, including Çöpler, Greater Çakmaktepe, and Bayramdere deposits, is within the Tethyan mineral belt, a terrane stretching from Indo-China to Europe through Eurasia that contains economically significant gold, copper, and base metal deposits.

The Çöpler Project is located near the north margin of a complex collision zone and to the south of the prominent North Anatolian Fault Zone (Figure 6-2). The collision zone, and subsequent crustal thickening, is related to the closure of the northern branch of the Neotethys ocean, resulting from the northward subduction and coming together of the Pontides and Tauride Anatolide Block in the Late Cretaceous to Early Tertiary. In this intensely deformed tectonic region, east trending imbricated structures were cut by north–northeast trending strike-slip faults during the Late Cretaceous to Paleogene period.

Three main rock assemblages are exposed in the Çöpler district (Figure 6-2 and Figure 6-3):

The local geology is a complex structural assemblage of fault-bounded blocks (Figure 6-3) including the following rock types:

Figure 6-4 shows a generalized stratigraphic column for the Çöpler area.
