After being first recognised as an elliptic topographic feature, field work at Mongae Creek identified an abundance of coarse, angular, and crystalline gold in the drainage system of a small valley where local miners are consistently recovering alluvial gold. Following a mapping campaign that encountered classic porphyry-style alteration and veining, Mongae Creek became Gold Mountain Limited’s priority target.
Samples recovered from mineralised outcrop and proximal floaters retrieved from the creeks have returned grades of up to 0.6 % Cu and 0.44 g/t Au. Gossanous, hydrothermally brecciated diorite is found in outcrop and as floaters in the creeks. These floaters are being crushed by locals and yield free gold.
A scout diamond drill programme commenced in 2018 and the first two drill holes have been completed. Assay results have been received for both holes. MCD002 returned a best intercept of 49m @ 0.12% Cu from 165m including 10m @ 0.22% Cu from 183m. In MCD001, the best intercept was 1m @ 243 g/t Ag, 0.8 % Cu, 522 ppm Co, 0.4 % Ni, and 0.7 % W from 38m. In both holes, the frequency of base-metal and Mo-bearing veinlets increases downhole, as do K, Cu, Zn, Mo and Pb grades. This is consistent with logging by field geologists of more intense alteration further down the hole and suggests closer proximity to a mineralising fluid source.The holes display chloritic and propylitic alteration, characteristic of a pophyry copper-gold system.
Gold Mountain Limited has commenced a detailed surface soil sampling programme over the entire catchment basin to assist in the next phase of targeted drilling.
