Deposit Type

  • Breccia pipe / Stockwork
  • Vein / narrow vein
  • Saprolite
  • Orogenic


Summary:

Kalana and Kalanako are orogenic gold deposits lying within a Birimian-aged volcano-sedimentary sequence of rocks.

The Kalana Project area lies along the western margin of the Bagoé Basin toward the southern extremity of the Yanfolila-Kalana volcano-sedimentary belt which forms the border with the Siguirri Basin in Guinea. Volcanic rocks, primarily basalt, are found in small domains in the eastern and westerns parts of the Basin, pinched along orogenic shear zones. A large Eburnean felsic intrusion, the Bougouni Batholith, occupies the central part of the Bagoé Basin. Small intermediate intrusions, commonly diorite and granodiorite, are mainly found in the eastern part of this area, as well as in the Kalana area. All rock types in the Basin are cut by (Neoproterozoic or potentially Jurrassic) dolerite dykes that are dominated by easterly, northeasterly, and north-northwesterly trends.

Gold mineralisation in the southern portion of the Bagoé Basin appears to be controlled by basinmargin parallel faults that generally trend northwest to north. The Bagoé Basin is host to the multimillion-ounce gold deposits at Morila and Syama.

The Kalana Project Area is covered by an extensive lateritic profile, characteristic of the Guinea Savannah climatic zone, obscuring the bedrock. The depth of weathering ranges from 30 m to 130 m.

The Kalana Project gold deposits are hosted by volcano-sedimentary rocks of the lower part of the Upper Birimian Gro ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The most recent mining at Kalana was underground, however to achieve the scale of mining required by the proposed processing plant the mining method going forward for the Kalana Gold Project is intended to be conventional open pit mining using a drill, blast, load, haul and tip mining cycle. Endeavour plans to contract out the mining to a suitable mining contractor whilst maintaining operation oversight.

The saprolite is anticipated to be primarily free-dig, potentially requiring ripping or only some very light drill and blast. Production drilling will be undertaken by top hammer drills drilling 127 mm diameter holes. As rock strengths increase, blasting will be utilised more regularly in the saprock with powder factors estimated at 0.38 kg/bcm. All the fresh rock will be blasted with powder factors estimated at 0.86 kg/bcm.

The underground voids are present and were surveyed, however despite the voids being typically narrow (<3 m) and flat dipping, drilling should be used to confirm their locations.

Ore will be tipped on:
- Strategic long-term (LT) stockpiles to increase the plant feed grade and for rehandle during later stage pre-strip.
- Run-of-mine (ROM) stockpiles for short-term rehandle to the crusher.

Waste will be tipped on:
- External waste dumps.
- Bund and road construction.
- Tails dam wall construction.

Within the deposit, mine-scale structural features affecting slope stability are l ........
