The Çöpler deposit is centred on composite diorite to monzonite porphyry stocks that are part of the Eocene Çöpler Kabatas magmatic complex dated (by Imer et al., 2013) The magmatic rocks have intruded into both the Keban and Munzur Formations.

The gold, silver, and copper mineralisation of economic interest at Çöpler deposit area is exposed in four adjacent open pits from east to west: Manganese pit, Marble pit, Main pit, and West pit.
The pits expose economic parts of the same orebody and the three eastern pits will likely join up as the mining progresses. The predominant rock types in the mine include limestone / marble, metamorphic rocks (mainly hornfels) and diorite-tonalite porphyry, locally with equigranular biotite-granodiorite intrusions. Supergene enrichment enhanced along synmineralisation and post- mineralisation structures plays an important role in localising highgrade gold mineralisation at lithological contacts, late-stage faults and shear zones, and fault / contact intersections.

Most of the gold mineralisation concentrated in six distinct areas in the deposit: Main, Main West, Main East, Manganese, Marble, and West. The mineralisation is considered to be related to fluids associated with diorite intrusions at depth and generally manifests as three closely related mineralisation styles across the six areas:
• Low-Grade Porphyry Vein Mineralisation.
• Intermediate Sulfidation Epithermal Mineralisation.
• Iron Skarn a ........

Open pit mining at the Çöpler project is carried out by a mining contractor and managed by Anagold. The mining method is a conventional open pit method with drill and blast and utilising excavators and trucks operating on bench heights of 5 m. The mining contractor provides operators, line supervisors, equipment, and ancillary facilities required for the mining operation. SSR provides management, technical, mine planning, engineering, and grade control functions for the operation. SSR currently operates a sulfide process plant and an oxide heap leach facility.

New pit designs were created in 2021 based on updated metal prices and costs.

The key aims of the optimised pit designs are:
• Minimise mining costs and maximise economic return by exposing the highest value ore with minimum waste mining.
• Address operational requirements for loading, hauling, slope stability, and rockfall, as follows:
- Loading – the phases were designed with a minimum operational width of 15–30 m between phases (depending on bench configuration) to allow efficient mining for the equipment scale.
- Hauling – generally, two exit haul roads per phase were included: the west bound exit to the crusher, low-grade stockpile, and west dump; and the east bound exit to the potentially acid forming (PAF) and non-acid forming (NAF) dumps. Haul roads are generally 15 m wide at a 10% gradient. Single-lane haulage traffic is allowed in the lower benches of the mine and is ........

The sulfide plant commenced commissioning in Q4’18. The basic flow sheet is comprises:
• Crushing and ore handling;
• Grinding;
• Acidulation;
• Pressure oxidation;
• Iron / arsenic precipitation;
• Counter current decantation (CCD);
• Gold leach, carbon adsorption, and detoxification;
• Carbon desorption and refining;
• Neutralisation and tailings;
• Tailings storage facility (TSF).

The incorporation of a flotation circuit into the existing sulfide plant to upgrade sulfide sulfur (SS) to fully utilise grinding and pressure oxidation (POX) autoclave capacity has completed construction and commenced commissioning on ore in January 2022. This addition to the sulfide plant is incorporated between grinding and acidulation, by taking a bleed / slip stream from the grinding thickener feed, floating sulfides, and returning the sulfide concentrate to the grinding thickener to be combined with direct feed.
