阿拉斯加州金顶金资源量增长42%

据Mining.com网站报道，富瑞黄金风险投资公司(Freegold Ventures)在阿拉斯加州的金顶(Golden Summit)项目资源量更新，其推断金属量增长42%至1720万盎司。

24日，公司宣布，这个位于阿拉斯加州中部的项目推定矿石资源量为43194万吨，平均金品位1.24克/吨，较2024年9月份估算的品位增长15%;推测矿石资源量为35761万吨，品位1.04克/吨，金资源量增长16%至1190万盎司。

金顶项目位于费尔班克斯东北30公里处，金罗斯黄金公司(Kinross Gold)的诺克斯堡(Fort Knox)矿以北大约6公里处。

“资源量更新凸显了金顶项目的潜力，并表明在某些方面还要继续努力”，公司总裁兼首席执行官克里斯蒂娜·瓦尔克特(Kristina Walcott)在电子邮件中表示。

“过去五年对公司来说是变革的时代，我们预计2025年将是激动人心的一年，公司计划钻探3万米”。

资源量大幅增长

2011年公司首次公布资源量，推定矿石资源量为779万吨，金品位0.69克/吨，金资源量为17.4万盎司;推测矿石资源量为2700万吨，金品位0.60克/吨，金资源量为52.6万盎司。从那以来，该项目资源量已经大幅增长。

24日的资源量更新依据是去年完成的2.5万米钻探，以及公司选冶试验结果。

更新为推定资源量

今年资源量更新重点是将推测资源量升级为推定资源量，为今年晚些时候开展的预可行性研究做准备。这项工作包括完成加密和扩边钻探以及品位升级。

钻探还应能增加资源量，并确定一个更小范围的高品位露天采坑，以减少运营和初始阶段投资成本。

金顶项目2016年初步经济评价结果显示，按照5%的折现率，项目税后净现值为1.88亿美元，内部收益率为19.6%，回报期为3.3年。初始投资为8800万美元。矿山寿命为24年，可生产黄金236万盎司，年产量为9.6万盎司。
