Çamyurt represents a very low capital and high return project given its close proximity and ability to utilize infrastructure at Agi Dagi.

Deposit Type

  • Epithermal
  • Breccia pipe / Stockwork

Summary:

The Çamyurt Gold deposit is high-sulphidation, epithermal gold deposit. Gold mineralization at Çamyurt is hosted within Miocene age andesitic tuffs or felsic volcanic rocks and phreatic breccias typical in some deposits of this type.

Çamyurt Gold Property is a highsulphidation, epithermal gold deposit. Premier examples of this kind of deposit in the world are Yanacocha, Pierina and Alto Chicama in Peru. Most high sulphidation deposits are large, low-grade bulk-tonnage systems (Yanacocha), though vein-hosted high-sulphidation deposits also occur (El Indio).

Drilling at Çamyurt has defined a mineralized zone that is continuous for at least 1,200 metres ("m") along strike with additional potential to extend mineralization to the northeast and at depth. Gold mineralization is hosted within a tabular, steeply-dipping oxidized zone starting at surface and with a cross-strike width up to 150m.

Turkey consists of crustal fragments assembled by early Tertiary time as the result of southerly
directed obduction events that recorded the collision of Gondwana and Laurasia. The Biga Peninsula is located in the western part of the Sakarya tectonic domain, which is bounded by the Intra-Pontide suture to the north and the Izmir-Ankara-Erzincan suture to the south. The Biga Peninsula is made up of several northeasterly trending structural domes composed of metamorphosed Paleozoic and Mesozoic basement rocks and intervening, east to northeast trending, extensional basins filled with Paleogene and younger volcanic strata. Exotic blocks of eclogite and blueschist occur in a tectonic mélange that forms part of a possibly Permian volcanic-sedimentary complex adjacent to the Kazdag massif north of Küçükkuyu.


Mining Methods

  • Truck & Shovel / Loader

Source:

Summary:

The Çamyurt deposit will be mined by conventional open pit hard rock mining methods. Alamos Gold plans to utilize a contract mining company to move the mineralized material and waste from the pit.

Çamyurt will be developed on the basis that the Project will have minimal stand-alone infrastructure. Mineralized material from Çamyurt will be mined and trucked approximately 8 km to be processed through the infrastructure at Agi Dagi once the Baba and Deli pits have been mined out.

A traditional drill, blast, load and haul sequence will be used to deliver mineralized material to the crushing circuit at Agi Dagi. Waste produced over the life of the mine will be sent to the waste rock dump located near the Çamyurt pit, or backfilled into the pit once the ultimate pit bottom has been achieved.


Crushing and Grinding


Processing

  • Smelting
  • Carbon re-activation kiln
  • Heap leach
  • Counter current decantation (CCD)
  • Carbon in column (CIC)
  • Elution
  • Carbon adsorption-desorption-recovery (ADR)
  • Solvent Extraction & Electrowinning
  • Cyanide (reagent)

Summary:

Çamyurt has been designed as a 15,000 t/d mining operation with mineralized material to be hauled approximately 8 km to the crushing circuit at Agi Dagi where it will be processed by primary and secondary crushing to a nominal size of 26 mm. The secondary crushed mineralized material will be drum agglomerated, stacked on the leach pad by conveyor stacking and processed with conventional heap leaching methods.

The crushed mineralized material will be stacked in 10 m lifts on the Agi Dagi leach pad facility which will be expanded in three phases and have an ultimate capacity of 73.6 Mt. This is sufficient to accommodate the 54.4 Mt Agi Dagi Mineral Reserve and 16.6 Mt of mineralized material included in the PEA mine plan for Çamyurt. A dilute cyanide solution will be applied to the crushed mineralized material over a 90-day leaching cycle with the pregnant solution collected and processed through the ADR plant where gold and silver doré will be produced.
