Gold Anomaly (ASX:GOA) requested that H & S Consultants Pty Ltd (formerly Hellman & Schofield Pty Ltd), an independent geological consultancy based in Sydney, Australia, undertake an assessment of the Exploration Potential for the Nevera prospect at Crater Mountain. A previous Inferred Resource of 24Mt at 1g/t Au for 790,000 ozs for the Main Zone of the Nevera prospect was estimated by Dr Andrew Richmond using a 0.5g/t gold cut off grade. Additional drilling by Gold Anomaly has now identified a much larger gold envelope to the Inferred Resource and this envelope combined with the Inferred Resource makes up the new Exploration Target for the prospect.
The Nevera Main Zone is a low-sulphidation epithermal carbonate – base metal sulphide – gold deposit of the “mixing zone” style. Mixing zone mineralisation is deposited predominately as veins, stockworks and breccia matrix when deeply penetrating downwards circulating carbonated groundwater mixes with rising hot mineralised magmatic fluids derived from a deep intrusive source. Other Pacific Rim examples include Kelian in Indonesia and Hidden Valley and Wafi in the Morobe Goldfield of Papua New Guinea.
