Deposit Type

  • Vein / narrow vein
  • Epithermal


Summary:

The Efemçukuru gold mine, an intermediate sulfidation epithermal vein deposit, is hosted in the center of a broadly NE-SW trending horst known as the Seferihisar Horst, which regionally exposes basement rocks of the Bornova Flysch in the Menderes Massif.

Local geology consists of intermediate sulfidation veins hosted by a low-grade metamorphic sequence of very fine-grained, black to dark grey shales to phyllite and schist that have been locally folded and intruded by rhyolite dikes. Mineralogy of the phyllites is fine-grained quartz, feldspar, muscovite, chlorite and rare biotite. The mineralogy of the schist is similar to the phyllite, comprising strongly deformed quartz, feldspar, chlorite and muscovite. A calc-silicate alteration, locally termed hornfels, occurs in a broadly NW-trending pattern in the center of the deposit area. The alteration commonly occurs as alternating dark green and tan-grey bands within meta-sedimentary rocks. The contact between calc-silicate alteration and phyllite is gradational. Rhyolite occurs throughout as 1 to 5 m-wide NW-striking dikes. Contacts of the rhyolite dikes with the flysch units are usually sharp.

Two major broadly NW-SE striking epithermal vein systems occur at Efemçukuru, namely Kestane Beleni and Kokarpinar, with strike extents of approximately 2 km and 4 km respectively. Both veins strike north-westerly (320°–340°), dip 60°E to 70°E, and can be traced on surface for strike lengths of over a kilometre. Bo ........


Mining Methods

  • Longitudinal open stoping
  • Drift & Fill
  • Longhole open stoping
  • Transverse open stoping
  • Paste backfill


Summary:

Efemçukuru mine employs small-scale underground mechanized mining methods to exploit the narrow, high- grade, subvertical mineralization.

Efemçukuru is an epithermal gold deposit comprising two major veins, Kestane Beleni and Kokarpinar, with Kestane Beleni containing the bulk of the ore. Both veins strike north-westerly (320°–340°), dip 60°E to 70°E, and can be traced on surface for strike lengths of over a kilometre.

The mine design has been developed to allow flexible access to all of the shoots. Four spiral footwall ramps at each orebody provide access for moving men, equipment, and supplies underground. Advantages of the four-ramp system include increased stope availability, more robust ventilation with increased equipment and labour productivity. All declines are interconnected by link drives, which serve as a secondary egress from the mine, spaced vertically 80–100 m apart.

Ore is truck hauled to a central ore pass system above the underground crusher before being conveyed to surface via a 380 m belt conveyor. The orepass system provides 3,500 tonne surge capacity for underground production with a further 5,000 tonne capacity in bins on surface. Waste
rock is hauled to surface via the South 672 Portal or North 656 Portal.

Drift & Fill (DAF) is the primary stoping method used for widths between 2 m and 8 m. This method allows selective recovery of ore within the orebody. LHOS is used where the ground conditions are am ........
