澳洲上市公司萨里托干石墨公司（Sarytogan Graphite）在哈萨克斯坦中部Ilksan矿点的首批钻探中取得重大发现，一口钻孔贯穿整个229米长的铜矿脉，全孔品位达0.14%铜 [1]。该项目位于该公司Baynazar铜矿勘探区内，距其石墨矿床仅25公里 [1]。
钻芯测试揭示了脉体内的高品位区间 [1]。在33.8米处发现了11.6米长、品位0.26%铜的矿化段；159.7米处则存在16.2米长的富集段，铜品位达0.36%，同时伴生0.12克/吨金和1.4克/吨银 [1]。公司管理总监Sean Gregory表示，"金刚石钻芯和分析结果表明存在富铜斑岩系统" [1]。距该钻孔仅10米处的两口苏联时代遗留浅孔总深度达320米 [1]，另外两口新完成的钻孔样品已送检，公司预计数周内获得检测结果 [1]。
Australian-listed Sarytogan Graphite has confirmed a significant porphyry copper system at its Ilksan prospect in central Kazakhstan, with initial drilling returning a full-hole copper intersection of 229 meters grading 0.14% copper [1]. The discovery, located within the company's Baynazar copper exploration project approximately 25 kilometers from its graphite deposit, demonstrates the presence of a substantial mineralized system [1].
The drill core revealed multiple high-grade zones within the broader intercept [1]. A 11.6-meter section at 33.8 meters depth returned 0.26% copper, while a more substantial 16.2-meter interval starting at 159.7 meters depth assayed 0.36% copper along with 0.12 grams per tonne gold and 1.4 grams per tonne silver [1]. Sean Gregory, the company's managing director, stated that "diamond core drilling and assay results indicate the presence of a rich copper porphyry system" [1]. Two additional boreholes positioned approximately 10 meters from the Ilksan hole have been drilled and samples have been submitted for analysis, with results expected within weeks [1].
