Deposit Type

  • Breccia pipe / Stockwork


Summary:

The Namoya Project lies on the western edge of the Kibaran Mobile Belt (KMB). The KMB is an intercontinental mobile belt which was formed during the Mesoproterozoic between 1.4Ga and 0.9Ga when the supercontinent Rodinia was formed. The KMB is also known as a metallogenic province.

The Namoya Project, even though segmented into separate prospects, boasts one type of gold mineralisation style. The following deposit characteristics have been noted:-
-gold mineralisation hosted within quartz veins and quartz stockworks, striking in a northwestsoutheast direction;

- prevalence of tourmaline crystals within the quartz veins;

- deformation structures within the quartz veins, resulting in irregular sheets, nested vein sets, ladder veins and micro-veinlets, characteristic of shearing;

- no granitic intrusions in the immediate area of the Namoya orebody (as a possible source of tourmaline) although quartz porphyry intrusions have been intersected by drill holes at Namoya Summit and Muviringu signifying potential for a deep seated granitic body; and

- sericite/chlorite schists, sometimes with carbonates, indicative of a magmatic and hydrothermal processes.

The deposit characteristics are typical of the intrusion-related, tungsten/tin-associated type. This class of magmatic-hydrothermal deposits occurs within magmatic provinces best known for tungsten and/or tin mineralization. This type of deposit contains a metal ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Mining operations are based on conventional drill and blast, load and haul mining techniques. Ore is drilled and blasted, and loaded by hydraulic excavators in backhoe configuration, with off highway dump trucks.

Excess RoM is stockpiled on the ROM pad, with low grade ore sent to the low grade stockpile, located approximately 400m from the RoM pad. Stockpiled RoM ore is sorted under a stockpile grade control management scheme, with stockpile reclaim undertaken by a front end loader, and then fed to the crusher as required. Waste material mined is hauled to close-by waste dumps.
