| 中文摘要: |
| 刚果(金)某铜钴矿产位于著名的卢菲利安弧铜钴成矿带上,勘探资源量为铜金属量30万t,钴金属量4万t。该铜钴矿项目为国内某上市公司投资标的项目,受上市公司委托,对矿区资源量可靠度进行初步评估。研究区含矿层位主要为罗安群矿山组,矿化类型主要为氧化铜钴矿。通过对验证钻孔与原钻孔的钻孔参数、施工质量、地层岩性组合、矿层样品品位及厚度进行综合对比,结果表明,验证钻孔与原钻孔的地层岩性组合、矿层样品品位及厚度吻合度较好。该矿区原钻探施工与编录质量合格、分析数据可信,资源量是可靠的。这为矿区后续资源量估算、矿产开发、矿产投资提供了依据。 |
| 英文摘要: |
| A certain copper-cobalt mine in the Congo (DRC) is located on the famous Lufilian arc copper-cobalt metallogenic belt. The exploration resources are 300,000 tons of copper and 40,000 tons of cobalt. The copper-cobalt mine project is an investment target project of a domestic listed company. It was commissioned by the listed company to conduct a preliminary assessment of the reliability of the resources in the mining area. The ore-bearing strata in the study area is mainly R2, and the mineralization type is mainly copper oxide cobalt ore.The evaluation method is to perform partial drilling verification in the mining area, through comprehensive comparison of the drilling parameters, construction quality, formation lithology combination, mineral layer sample grade and thickness of the verified drilling and the original drilling. Through comparison, it is verified that the stratum lithology combination, grade and thickness of the ore samples of the drill hole and the original drill hole are in good agreement. The results show that the original drilling construction and cataloging quality of the mining area are qualified, the analysis data is credible, and the resources are reliable. This study provides a basis for resource estimation, mineral development, and mineral investment. |
