Drilling at Leane’s has confirmed the presence of copper-bearing breccia and porphyry intrusions. The geological environment, including structure and mineralisation, encountered through drilling at Leane’s is considered anomalous to that found in the early stages of exploration at the Mungana, Griffiths Hill and Red Dome deposits.

Leane’s Prospect
Glenroy Prospect
The Glenroy Prospect comprises the Glenroy and Fairlight prospects, each hosting historical small copper-gold mines and mineral occurrences. Mineralisation is associated with the basalt-dominated Chillagoe Formation, with historical workings aligning with a discrete magnetic high that may be the alteration signature due to magnetite or pyrrhotite. Previous exploration has identified widespread copper and gold stream anomalies, yet the areas remain relatively underexplored.
Glenroy Prospect
The Bald Hill and Mountain Creek prospects lie in the central part of the Palmerville Project on EPM 18325, 10km south of Leane’s. Exploration is focused on the delineation of porphyry copper-gold, skarn and volcanic massive sulphide (VMS) copper-gold, lead and zinc style deposits within the highly prospective Chillagoe Formation. Bald Hill is a discrete magnetic high associated with a microgranite plug. Immediately south of Bald Hill, the historic Mountain Creek copper workings appear to lie on a north-westerly trending structural zone.
