Kalumbila Project - Licence 267

The Cu/Ni is hosted in a carbonaceous shale unit with a currently determines strike of 11km. Kiwara correlates this unit as being equivalent to the Copper-Belt ore shales.

Historic regional soil geochemisty work by RST identified a copper anomaly which was first drilled in 1960 and led to the identification of nickel mineralisation at the north eastern end of the unit. This became the focus of a follow up drill programme and subsequently a programme conducted by Anglo American.

RST drilled a total of 31 core boreholes, the logs and physical core of which is still available at the Zambian Chamber of Mines, Kalalushi.

In 2007 Kiwara conducted geochemistry and geophysics (ground EM) programmes together with an initial drill programme to determine the up-dip potential. The most significant development of the initial exploration programme was the identification of near surface copper mineralisation (LR3).

This became the focus on subsequent exploration which included the drilling of 31 core boreholes. Click here to see the table.

In early 2009 Snowden Mining Consultants were commissioned to conduct an independent initial resource estimation (see below).

On the basis of the Resource Statement, Kiwara is now conducting in-fill and strike extension drilling with a view increasing the definition of the resource for a mining feasibility study.
