Altus Strategies (ALS ) has unveiled encouraging initial results from the ongoing 10,000m Reverse Circulation ("RC") drilling programme at its 100% owned Diba gold project in western Mali.
The 81km2 Diba gold (Korali Sud licence) project is located in the Kayes region of western Mali, approximately 450km northwest of the capital city of Bamako.
The mining royalty firm said it has received “excellent results” from the ongoing drilling at Diba (Fig. 1), including 3.34 g/t Au over 60m from 17m downhole from within the Diba Deposit.
The RC drilling programme is currently being undertaken by Capital Drilling Limited and once complete, will comprise approximately 110 holes totalling approximately 10,000m, it noted.

Approximately 4,800m (over 52 holes) is being drilled in and around that part of the Diba Deposit subject to the MRE, testing the potential down dip and along strike extensions, as well as infilling areas to increase the resource confidence. Approximately 5,200m is being drilled to test up to five priority prospects each located within 3km of the Diba Deposit.
The drilling programme is also testing satellite prospects to the main Diba Deposit (Fig. 2).
Initial results received from the Diba NW prospect indicate the discovery of two potentially significant, shallow-dipping and consistent zones of mineralisation totalling approximately 750m in strike length with intersections including 0.87 g/t Au over 21m from 79m (Fig. 3).

As part of testing the potential extension of the Diba MRE, drilling was undertaken along strike ( north and south), down-dip (to the east), targeting potential for lenses to the west (Fig. 4).
The results received to date confirm potential on strike and down dip extensions, including continued mineralisation down-dip in the east and continued mineralisation up-dip to the west.
The group said it is also “highly encouraged” by intercepts outside the margins of the current MRE envelope, indicating along strike and down-dip continuation, including 4.48 g/t Au over 15m from 22m on its western side and 22.11 g/t Au over 6m from 89m on its eastern side.

The Company said it intends to incorporate the results from the current drill programme when all have been received and compiled into an updated MRE for the Diba Deposit.
“A number of priority prospects have not been tested in the current programme and we anticipate that these will be drilled in a follow-up programme, once physical access to the drill rig is complete,” said Poulton who added that the further assay results would soon be shared.
