Orion Gold’s Connors Arc Project is located 180km from Rockhampton in Central Queensland. The Project comprises six granted EPMs covering 1096km2 and further applications which, if granted, would take the project area over 2,300km2.
The project is located on the highly prospective “Connors Arc” which forms part of the Palaeozoic, New England Fold Belt of Eastern Australia. This belt has delivered several large, successful epithermal gold mines such as the Pajingo, Cracow and the Mt Carlton deposits.
Orion’s Connors Arc project area is located within a geological and structural setting very similar to other significant epithermal gold systems in Queensland. Notable features include close proximity to the eastern margin of the Bowen Basin and prospective, Permo-Carboniferous aged volcanic and intrusive lithologies. In addition:
Fieldwork conducted by the Company in 2014 and 2015 has outlined a substantial and highly prospective intermediate sulphidation gold-silver target at Aurora Flats and extending to the north beyond Veinglorious. This style of deposit is globally significant and accounts for a substantial proportion of world gold production. Examples include Acupan, Baguio in the Phillipines and Pachuca in Mexico.
Reconnaissance field mapping traced the surface expression of outcropping veins and allowed observation and interpretation of the textures of these veins. Vein textures are a strong diagnostic feature for depth of formation in epithermal mineral systems. The program also incorporated a review of the historical exploration database with particular focus on re-interpretation of the geology and geochemical data from the shallow drilling.
The review was carried out by Prof Noel White and Bruce Wilson, both highly experienced epithermal mineralisation experts. Their key findings were:
|LHS: plan showing high resolution Reduced To Pole ("RTP") ground magnetic data, indicating mag low anomalies correlating to west dipping epithermal vein systems at the critical target depth for gold deposition. RHS: 1st vertical derivative of the same data on the LHS, with dashed line indicating location of a narrow mafic dyke that follows the mineralised structure. White ovals outline target areas for drillings.|
