Broken Hill Mines、Gorilla Gold和Meeka Metals三家澳大利亚上市矿业公司近期公布了各自项目的重要钻探成果。[1]
Broken Hill Mines在其Rasp矿的Centenary区发现了一条高品位矿化带，钻探拦截长度25.8米，锌当量品位达11.7%，其中10.9米矿段的锌当量品位高达17.3%。[1]这一发现超出了该公司现有资源模型的预期，矿化带的厚度比预期增加5倍，品位高出27%。[1]Centenary区目前推断资源量为480万吨，平均品位9.2%锌当量。[1]该矿化体距离现有地下开采操作仅约250米。[1]
Gorilla Gold在Comet Vale项目的Sovereign矿脉下盘发现了9.3米的矿化体，品位为20.6克/吨黄金。[1]该公司北卡尔古利枢纽中心当前资源量约120万盎司，平均品位3.7克/吨黄金。[1]
Meeka Metals在Turnberry矿深部的钻探中拦截到52.3米的矿化带，品位为3克/吨黄金，其中30.6米矿段品位为3.4克/吨，10.5米矿段品位为3.7克/吨。[1]Turnberry矿现有690,000盎司黄金资源。[1]三家公司均表示将进行后续钻探以确认矿体的规模。[1]
Three Australian Securities Exchange-listed mining companies have reported significant drilling results across their respective projects. Broken Hill Mines encountered high-grade mineralization at its Rasp mine's Centenary Zone, intercepting 25.8 meters grading 11.7% zinc equivalent, with a core interval of 10.9 meters grading 17.3% zinc equivalent [1]. This discovery substantially exceeds the company's resource model expectations, with the intercept width five times wider and grade 27% higher than predicted [1]. The mineralized body lies approximately 250 meters from existing underground mining operations [1]. The Centenary Zone currently hosts 4.8 million tonnes of inferred resources at an average grade of 9.2% zinc equivalent [1].
Gorilla Gold reported a 9.3-meter intercept grading 20.6 grams per tonne of gold in the footwall of the Sovereign vein at its Comet Vale project [1]. The Northern Kalgoorlie Hub currently contains approximately 1.2 million ounces of gold resources averaging 3.7 grams per tonne [1]. Meeka Metals intersected 52.3 meters grading 3 grams per tonne gold at depth in the Turnberry mine, including higher-grade intervals of 30.6 meters at 3.4 grams per tonne and 10.5 meters at 3.7 grams per tonne [1]. The Turnberry mine presently holds 690,000 ounces of gold resources [1]. All three companies intend to pursue additional drilling to further define the scale of their respective mineralized bodies [1].
