Brisbane, June 2, 2008 AEST (ABN Newswire) - The Board of Republic Gold (ASX: RAU)("Republic" or the "Company") announces that it has received a positive petrology report for the Burraga Base Metals Prospect. This report indicates that Burraga mineralisation fits what is known as the "carbonate-base metal" model of mineralisation. A number of significant mineral deposits of this style are located in the south-west Pacific Rim including Kelian, Gold Ridge, Mt. Kare, Porgera, Woodlark Island, Karangahake and Lake Cowal.
A petrologist report looks at samples of rock from a mineral deposit under a microscope to determine in detail what minerals compose the rock and what rock types are present. Because of the differing ways in which mineral bodies are formed geologically, there are common assemblages, or groups, of minerals for particular mineralisation styles. In the report on the Burraga rock samples the petrologist makes numerous technical mentions of hot hydrothermal fluids, biotite/phlogopite alteration, adularia-carbonate-silica alteration and proximity to a nearby intrusive (the source of later alteration and sulphides) and describes an alkaline trachybasalt dyke rock.
This description fits well with the "carbonate-base metal" model of mineralisation, being a distal part of a porphyry system. This also adds weight to the possibility that Burraga could be a large mineralised system.
This new knowledge can be used to better target holes for the next drilling programme. The company's current strategy is to complete the relatively modest programme of 5,000 to 8,000 metres previously announced to the market. Following receipt and interpretation of analysis results, this programme is expected be followed up with a larger drill-out programme for resource estimation.
