Assay results up to 13% cobalt from artisanal pits and trenches.
Mining readings

  • Mwilu Project covers an area of 3.36km2 that contains zones of the Roan stratigraphy
  • Artisanal mining is active within the project area with high-grade Cobalt mineralisation being extracted
  • Initial reconnaissance sampling by Taruga has returned assay results up to 13% Co from artisanal pits and trenches
  • Field mapping indicates that the Roan stratigraphy is present through the project area

Mwilu covers 3.36km2 within the Kolwezi “Klippe” (Figure 2) which hosts a number of the largest known cobalt and copper mines and borders the city of Kolwezi to the north. The area is currently being mined at shallow levels by artisanal miners who are providing cobalt ore to the Consortium, the sale of which is used to fund ongoing development projects in the Lualaba Province. The Company is in discussions with the vendors of Mwilu for possible early stage production at shallow levels on the two projects.

Taruga recently conducted a reconnaissance sampling and mapping programme at Mwilu to confirm historical mapping carried out by La Générale des Carrières et des Mines (Gécamines). Samples were collected from a number of artisanal pits and a series of trenches in the NW corner of the project area. Results using a portable XRF analyser are summarised in Table 1 with significant results for grab and channel samples shown in Figure 3.

At shallow levels, no significant copper grades were reported, confirming a dominance of cobalt mineralisation at Mwilu. Drilling will confirm potential copper mineralisation at depth.

Note: Samples at Mwilu were prepped by ALS Global in Lubumbashi and analysed with a portable XRF analyser (Niton). Duplicate samples have been sent to ALS Global in Johannesburg, South Africa for analysis using. Results from the Niton are expected to be reliable due to the low iron content (<6% Fe) which is likely to cause interference with cobalt readings when >6% Fe.

Mwilu Project – Geology Enhanced

  • Mwilu Project located in an area of thrust faulting and folded geological sequence
  • Project area has an area of 2km x 1.3km of potentially mineralised Roan sediments
  • Interpretation of geology indicates fold repeated sequence with depth potential down to 350m
  • Initial mapping and reconnaissance has confirmed mineralisation in the Roan stratigraphy
  • Proposed exploration consists of additional surface sampling and drill testing to determine depth potential of high-grade mineralisation
