Name of the Project
Khoemacau copper/silver project.
Location
North-west Botswana.
Project Owner/s
Khoemacau Copper Mining (KCM), a subsidiary of Cupric Canyon Capital.
Project Description
The project entails the construction of KCM’s 3.6-million-tonne-a-year starter project, processing ore from the 91-million-tonne resource at a head grade of 2.02% copper and 21.4 g/t silver copper.
The company plans to develop the Zone 5 orebody as three separate underground mines, each producing 1.2-million tonnes a year on average for the first five years.
Each of the mines will have its own independent ramp access and operate over a strike length of about 1 000 m, extracting ore using a conventional sublevel open-stoping mining method.
The mined ore will be trucked 35 km to the Boseto processing facility, which will be refurbished and enhanced to process 3.65-million tonnes a year. Processing will be conventional sulphide flotation using three-stage crushing, ball milling and flotation, which will produce a high-quality copper concentrate grading at about 40% for shipment to African and international smelters.
The underground mine will be fully mechanised.
Initial production is estimated at an average of 62 000 t/y of copper and 1.9-million ounces of silver.
In addition to Zone 5 resources, there are a further 93.5-million tonnes of high-grade ore grading 1.9% copper and 33 g/t silver across the Khoemacau project. KCM plans to develop these resources in conjunction with the construction of the starter project.
The long-term plan is to expand Khoemacau to about 5.8-million tonnes a year through the expansion project, whereby a new standalone process plant will be built at Zone 5. The project is expected to produce more than 100 000 t/y of copper.
