Cobre’s Ngami in Botswana is WhyAfrica’s Pick Of The Week

ASX listed exploration company Cobre Limited has announced more encouraging results at its Ngami Copper Project (NCP) within the Kalahari Copper Belt (KCB) of Botswana.

Cobre owns 51% of Kalahari Metals Limited, a private UK company that controls approximately 8,100 km2 of tenements within the KCB of Botswana.

Under layers of sand, the north-eastern flank of the Kalahari Craton in central Namibia and Botswana, hosts what geologists refer to as magmatic arch rock which contains Sediment-hosted stratabound-type copper (Cu) deposits.

Overlying the arch rocks is the Tsumis Group of rocks which extends northeast from Namibia for hundreds of kilometres into Botswana, where it is known as the Ghanzi Group.

The Tsumis and Ghanzi groups include copper and silver deposits that constitute the KCB.

The belt is 1000km long and in places up to 250km wide. In Namibia, the KCB includes the Klein Aub, Oamites and Witvlei deposits. In Botswana, several mineral exploration companies are probing the Kalahari Belt while production is imminent at Sandfire’s Motheo and Khoemacau Copper Mining is ramping up to full production at its copper and silver mine.

Not far from Cobre’s Ngami project site, Australian exploration outfit Sandfire Resources is developing the Motheo copper project. Motheo is scheduled to start producing its first concentrate as early as next year. The mine is in an advanced stage of development. Sandfire also holds tenements in Namibia and is set to become one of the major copper players in the KCB of Botswana and Namibia. The company recently announced further expansions at its Motheo project.

Further north-east and close to the village of Toteng in Ngamiland, one of the first movers in the Kalahari, Khoemacau Copper Mining, has developed the impressive Khoemacau copper and silver mine. The Boseto mine, processing plant and infrastructure initially developed by Discovery Metals Limited (bought by Khoemacau Copper Mining in 2015) is an important part of Khoemacau’s operation and specifically the now upgraded processing plant with its associated infrastructure. The Boseto processing plant is about 35km from Khoemacau’s Zone 5 new flagship underground mine.




Cobre’s results send share price skyrocketing

Exploration company Cobre Limited’s initial results at Ngamiland sent their share price skyrocketing on the Australian Stock Exchange two months ago. Last week the company announced the sixth intersection of copper mineralisation from its ongoing drilling programme on Kalahari Metals Limited’s NCP licenses.

Drilling targeted the lateral extension of highly anomalous mineralisation intersected at previous holes and has delineated a compelling copper target with more than 4km of strike. According to a statement by the company this copper intersection provides confidence in the continuity of mineralisation along the extensive strike extent.

The sixth hole of the ongoing drill programme at NCP intersected an 18m zone of visible copper mineralisation (down hole) which includes 9m of notable visual chalcocite mineralisation.

According to Martin Holland, Executive Chairman and Managing Director at Cobre, this is another significant result. “The result gives us confidence that the significant copper mineralisation intersected so far has lateral continuity along the extensive strike length of the target. We look forward to updating the market with further results from the 500m spaced drill programme along with assay results as these become available. Given the success of the first six holes in this diamond drill program, the company is fast tracking exploration with a second drill rig mobilising to site,says Holland.

Two weeks ago, Cobre announced good results from its fifth drill hole as well. The company then stated in an ASX announcement that mineralisation consists primarily of fine-grained chalcocite which occurs as fracture-fill and along bedding planes, with larger ‘blebs’ in carbonate-quartz veins.

“In addition to the primary chalcocite dominated zone, several intersections of bornite and chalcocite have been noted in quartz-carbonate veins.

“Mineralisation is steeply dipping and partly overturned with evidence of gentle folding based on oriented structural measurements. Mineralisation is expected to sub-crop under approximately 65m of cover extending sub-vertically beyond 315m depth.”

The ongoing drill programme is testing the first of 55 ranked targets across KML’s extensive license holding, including 43 targets on the relatively unexplored northern margin of the KCB. KML has commenced with soil sampling programmes on both northern margin projects (NCP and Kitlanya West) with a view to advancing several of these targets for drill testing in the short to medium term.
