Athena Resources Limited (ASX: AHN)于2025年11月27日宣布,其位于西澳大利亚州中西部铁矿石省份的Byro South探矿区已完成首次矿产资源估算(MRE, Mineral Resource Estimate),结果令人振奋。此次估算显著扩大了公司的磁铁矿资产组合,为Byro磁铁矿项目的未来发展奠定了坚实基础。
根据公告,Byro South探矿区的首次推断资源量(Inferred Resources, 地质置信度最低的资源级别)达到4700万吨(Mt),铁品位为29%。这一新增资源使得Byro磁铁矿项目(包括Byro South和旗舰FE1矿床)的总资源量实现了160%的大幅增长,总计达到7630万吨,综合铁品位为26.1%。
运营方面,初步的冶金测试工作显示,Byro South的矿石特性与FE1矿床相似,具有相似的戴维斯管回收率(DTR, Davis Tube Recovery, 一种衡量磁选效率的实验室测试方法),平均为32%。这意味着该矿石有望通过加工生产出含铁量约70%的优质磁铁矿精矿,为延长项目寿命和扩大生产规模提供了可能性。
公司董事总经理兼首席执行官Peter Jones表示,这一成果是勘探项目取得的激动人心的进展,Byro South有望成为Byro磁铁矿项目规模扩张的重要机遇。 Byro South项目计划采用传统的露天开采(Open pit mining)方式进行资源开采,选矿流程将包括破碎、研磨和磁选。
公司下一步将致力于将资源量的置信度提升至控制资源量(Indicated Resources, 地质置信度高于推断资源量)或更高级别,并启动范围研究(Scoping Study, 评估项目经济可行性的初步研究)以指导未来的资源钻探和开发决策。此外,Athena还将继续探索该区域其他三个探矿区的资源增长潜力。
