NMR holds two projects in Queensland. 9 exploration permits cover
1820km2 and 130km of the Palmerville Fault and comprise the flagship
copper/gold Palmerville Project.
Mount Morgan in Central Queensland is prospective for copper/gold mineralisation.
NMR’s flagship Palmerville Project comprises 9 exploration permits in the highly prospective Chillagoe Formation which hosts the large Red Dome, Griffiths Hill and Mungana porphyry gold-copper and polymetallic deposits.
NMR’s priority at Palmerville is the development of the Leane’s copper/gold prospect within EPM 11980. The Palmerville Project area also holds an additional 66 potential copper/gold mineralisation occurrences worthy of further investigation. Following initial desktop studies NMR has prioritised these into:
Priority 1: Leane’s Prospect EPM 11980
Priority 2: Glenroy, Fairlight and Little Kennedy Prospects Bald Hill Prospect
Priority 3: all other prospects
During late 2020 NMR carried out a drilling programme at Leane’s and were successful in confirming the presence of copper bearing breccia and porphyry intrusions. The geological environment including structure and mineralisation encountered is considered anomalous to that found in the early stages of exploration at the Mungana, Griffiths Hill and Red Dome mines.
Glenroy, Little Kennedy and Fairlight
Host to a number of historical small copper/gold mines and mineral occurrences, these three prospects make up the Glenroy Prospect. Hosted by basalt-dominated Chillagoe Formation the workings are coincident with a discrete magnetic high that may be the alteration signature due to magnetite or pyrrhotite associated with mineralisation. Widespread copper and gold stream anomalies have been noted by previous explorers. The areas are relatively under explored and once initial desk top studies have been completed, NMR is planning an exploration programme including soil sampling and an initial RC drilling programme.
The Bald Hill and Mountain Creek prospects lie in the central part of the Palmerville Project on EPM 18325 approximately 10 km 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 which hosts the Mungana and Red Dome mines.
Bald Hill is a discrete magnetic high associated with a microgranite plug with sparse rock chip sampling returning up to 0.26 ppm Au. Immediately south of Bald Hill, the historic Mountain Creek copper workings appear to lie on a northwesterly trending structural zone, with one rock chip sample returning 0.575 ppm Au coincident with a small magnetic anomaly.
