Kisladag is a low-grade, bulk-tonnage, open pit operation that uses heap leaching for gold recovery. Kisladag is one of the largest gold mines in the Turkiye.
Planned activities at the Kisladag for 2024 include includes the continuation of the waste stripping campaign, the phased expansion of the North Heap Leach Facility, and construction of the North ADR plant. |

- Porphyry
Summary:
The Kisladag deposit is classified as a gold-only porphyry deposit due to its exceptionally low Cu%/Au ppm ratio (˜ 0.03; Baker et al., 2016). Significant analogues include the Maricunga porphyry deposits (9.8 Moz Au) in Chile and La Colosa (33.2 Moz Au) in Columbia. The low Cu/Au ratio may in part be related to the shallow level of emplacement (< 1 km) and volcanic setting, but also reflects the post-collisional extensional setting of the Miocene in western Turkey (Baker et al., 2016). Nonetheless, the deposit shares many characteristics with typical porphyry systems including: (i) multi-stage porphyry intrusions; (ii) a zoned alteration system that contain a high temperature potassic core, an outer white mica-tourmaline zone (analogous to phyllic alteration in typical porphyry deposits) and late, high level advanced argillic alteration; and (iii) porphyry style stockwork veins.
The Kisladag deposit is hosted by a suite of subvolcanic monzonite porphyry intrusions that are subdivided into Intrusions #1, #2, #2A, and #3. Intrusion #1 is the oldest, and generally best mineralized phase. It forms the core of the system and is cut by the younger porphyritic intrusions. It is an E-W oriented elongate elliptical body in map view (~1,300 m x ~500 m), and in the subsurface has a sill-like form intruding along the contact of the basement and volcanic package. At depth the main body extends beyond the current limit of drilling (~1,000 m). Contacts between Intrusion #1 and ........
Summary:
Kisladag is a large tonnage, low grade operation. Mining and processing activities operate 24 hours a day, seven days a week. The mining operation is a standard truck and shovel operation using owner operated equipment and labour. All mined rock requires blasting. The blast holes are sampled and analyzed in-house for detailed grade control.
The mine fleet includes seven diesel drills, two electric drills, one 29 m3 electric hydraulic shovel, two 21 m3 diesel hydraulic shovels, two 21.4 m3 wheel loaders, one 12 m3 wheel loader, fourteen 136 tonne trucks and ten 219 tonne trucks. The major equipment is supported by a fleet of graders, dozers, a backhoe and water trucks.
Ore and waste are mined on 10 m benches. Ore will be hauled to the primary crusher for processing and waste rock will be placed in the south rock dump (SRD) and the north rock dump (NRD).
The final depth of the pit will be to the 520 m bench with a final wall height of 565 m to the highest point on the pit rim.
The ultimate pit haulage road allowances have been designed for 35 m width at 10% grade. This width will provide adequate room for ditches, outside berm and travel width for 219 tonne trucks. In the “Friable Zone” haulage road width has been increased to 40 m to allow for potential bench face instability.
