GOLDEN Cross Resources has received encouraging results from drilling at the Copper Hill Copper-Gold Project in the Central West of New South Wales.
The current program has further tested mineralized zones defined by historic drill-holes and has refined the Copper Hill geology model.
The updated geology model will provide more precisely defined constraints for the planned mineral resource estimation and has supported compliance with the JORC Code, 2012 Edition. Tenders have been called for the preparation of an updated resource estimate for Copper Hill. Preliminary financial modelling will then be run using various mine and mill throughput rates to determine potential viability.
The company is most encouraged by one hole which returned a substantial intersection of 178 metres @ 0.48% copper and 0.93 grams/tonne gold with a best higher grade zone of 40 metres @ 0.81% copper and 2.04 grams/tonne gold.
Other highlights of the recent drilling program are 55 metres @ 1.8% copper and 5.7 grams/tonne gold, including a bonanza zone of 12 metres @ 3.1% copper and 12.0 grams/tonne gold; 65 metres @ 0.58% copper and 0.44 grams/tonne gold, including 9 metres @ 1.2% copper and 1.13 grams/tonne gold; 50 metres @ 0.56% copper and 0.83 grams/tonne gold within a broad zone of 426 metres @ 0.39% copper and 0.39 grams/tonne gold; and 58 metres @ 0.64% copper and 0.68 grams/tonne gold.
PQ and HQ core sample assays have been returned from the ALS laboratory in nearby Orange. The Copper Hill project is to the north of the small town of Molong, northwest of the city of Orange. It is Golden Cross’ most advanced exploration project.
Structural observations of veins in the high grade central zone support the interpretation that the hole with the 178 metre mineralized intersection has cut across a north plunging zone of higher grade mineralization that was intersected in previous drill holes with north-south orientations. Holes drilled to the north drilled down the plunge of the zone, and those drilled to the south drilled through the zone, close to perpendicular.
This north plunging interpretation provides a potential vector to deeper, high grade targets and possible mineralization sources. If this orientation is supported elsewhere at Copper Hill there are implications for refining the resource model, and for further drilling. An example is the target zone defined beneath another hole between Central Copper Hill and Buckley’s Hill to the north.
