梅塔纳矿产公司于四月末公开了其在西澳大利亚州的2300万澳元的梅格尼特山金矿工程。梅格尼特山地区以往已产出62.6吨黄金,矿石平均品位为11.2克/吨。据公司地质人员估计,该地区还余有品位为6克/吨的1000万～1200万吨矿石,另还有远景矿量。梅格尼特山处于太古代一高度矿化的南北向绿岩带的中心,此岩带的组成是:酸性的及基性的火山岩、超基性岩流浸入体、沉积物(包括条带状含铁层和隧石)及花岗岩侵入体。南北走向的梅格尼特山大断层将岩带分割成东、西两个主要地域。金的矿化物
Metana Minerals opened its $ 23 million Magnet Hill Gold Project in Western Australia in late April. The Meginit Hill area has historically produced 62.6 tonnes of gold with an average grade of 11.2 g / t. According to the company’s geological staff, there are still some 10 to 12 million tons of ore of grade 6g / t remaining in the area, as well as the prospect of mined ore. The Mount Magnet is in the center of the Archean, a highly mineralized north-south paragneite belt composed of acidic and basic volcanic rocks, ultrabasic lithofacies, sediments (including bands Like ferrous and tunnels) and granite intrusions. The north-south Megusite fault cuts the rock belt into two major areas, east and west. Gold mineralization
