Gorilla Gold Mines' (ASX:GG8) drilling at the Sovereign deposit in Western Australia has the potential to add material ounces to the Sovereign mineral resource estimate, Euroz Hartleys said in a Thursday note.

Its growth drilling at the Comet Vale gold project in Western Australia expanded the high-grade footwall system at the Sovereign deposit, with results of up to 2.8 meters at 31 grams per tonne gold from 379.1 meters and 0.6 meters at 86.2 g/t gold from 99.4 meters.

The footwall lode sits 40 meters into the footwall of the main lode at Sovereign.

The investment firm maintained its speculative buy rating on the firm, as well as an AU$0.80 per share price target.
