The Garden Gully Gold Project comprises a 677km2 tenure package covering the Abbots Greenstone Belt (AGB). The project has multiple gold prospects along the belt with the most advanced being the Crown Prince Prospect.
The Abbots greenstone belt is a structurally deformed Archean-age package of mafic, ultramafic, and felsic volcaniclastic rocks that is prospective for gold and base metal deposits. Gold mineralisation is associated with quartz veins in various rock types including sediments, volcaniclastics, mafics and ultramafics, and has a spatial association with the northeast trending Abernethy Shear Zone which may represent the northern extension of a major structure which passes through the large Big Bell deposit.
Historical production from the AGB has come predominantly from two locations: the Crown Prince (formerly Kyarra) that produced about 21,000 ounces of gold averaging 21 grams per tonne; and the Abbotts Centre in the north, where the Mount Vranizan and New Murchison King mines together produced over 41,000 ounces of gold at an average 31 g/t Au.
Ora Gold has published a modest Mineral Resource at Crown Prince (see ASX announcement 21 October 2019). This resource comprises 479kt @ 3.6g/t Au for 55koz Au.
Further infill and deeper drilling are likely to delineate additional resources in the new mineralised structures outside of the known resource.
A Mineral resource Estimate (Table 1) for the Crown Prince deposit was announced by Ora Gold Limited on 21 October 2019.
It is clear that the AGB is endowed with gold mineralisation: the challenge is to unlock the structural controls on that mineralisation so that we can locate it and define zones that hopefully lend themselves to commercial exploitation. The Garden Gully Gold Project is very exciting and offers significant potential for success.
