  矿业项目评估——SRK观点
Grant Malensek,矿业金融现状会议,2015年4月28日

摘要:矿业估值需要考虑的方面包括矿体、现场条件、采矿风险、资源国家主义、税收和运营社会许可等。
 
Fedorovo酸性岩排水金属浸出(ARDML)评价项目中矿产品返还(NSR)的运用
A. Fortygin, J. Martschuk, J. Robertson (Barrick), R. Bowell, M. Dey, 2009

关键词:酸性岩排水金属浸出(ARDML)、铂族矿物(PGM)、铜、镍、净冶炼回收率(NSR)、Fedorovo

摘要:矿山酸性岩排水(ARD)和金属浸出(ML)潜力评价的标准方法是结合蚀变和/或矿石类型评估各种岩性。这些岩性的变化是指材料类型,并进一步再划分为反应材料或惰性废料和矿石,以确定他们的处理或存储要求。然而,这些材料通常在项目早期预可行性或可行性阶段进行划分,并且在地球化学评价期间保持该划分结果。项目经济后续变化可导致需要对材料重新分类,但这通常难以在地球化学测试中将这些与样品产生联系。俄罗斯西北科拉半岛Fedorovo项目近期可行性研究将净冶炼回收率(NSR)加入到材料类型分类体系来解决这一问题。本文呈现了目前ARDML研究结果,以及如何运用NSR值确定矿山运营和闭矿期间废物管理的材料类型和可能结果。

  局部各向异性角度品位建模:一个实用性观点
David F. Machuca-Mory, Harri Rees, Oy Leuangthong, APCOM 2015

摘要:资源地质学家常常发现,对于结构复杂的矿床来说,使用空间连续性不足的单一静态模型的地质统计算法进行品位建模,是不合适的。目前,解决这一问题的较为实用的方法是坐标转换或者或局部改变空间连续性的参数。这两种方法的共同特点是,需要建立品位空间连续的局部各向先验模型。本文着重探讨了由地质线框信息建立的局部各向异性角度模型的不同实际方面。内容包括获取局部变异角度的方法,对这些角度进行预处理的动机和方法,以及用于矿产资源估算中使用的局部各向性角度模型建立的方法。本文中基于向量内积的统计数据是一种简单的工具,用于对比不同领域的局部各向异性角度。此外,位于加纳的某一地质结构良好的金矿床运用了局部各向异性角度克里格法,并评估了使用预先处理的角度和替代角度领域的影响。
 
地质的艺术和科学:资源模型——不只是将品位填入矿块
Chad Yuhasz, SRK 加拿大, CIM 2015

摘要:资源估算的5大基本点包括:1.矿床合理取样;2.数字数据库的整合;3.理解矿床地质并合理运用在资源估算的过程中;4.使用合理的估算技术;5.使用合理的分类方法。资源建模可通过计算机、软件和专业知识建立自己的概念。
 
老挝东北部Vieng Kham项目Nam Xiang断层中的金矿化带
M Greentree, M J M Cunningham, J H Liu, 2015

摘要:老挝东北部的古生代岩石对黄金探险家们有着强大的吸引力,由于其复杂的构造历史,以及缺乏历史勘探。联合矿业公司对该区域进行了勘探以探索黄金。这包括了水系沉积物和岩石芯片采样以及航空地球物理学。随着进一步更详细的勘探,发现了地球化学异常,其中包括地质填图和土壤采样。钻探表明黄金矿化赋存于平行于Nam Xiang主要断层的结构和纤维织物中。高品位黄金伴随着强碳酸盐蚀变的角砾砂岩。这表明后期结构如Nam Xiang断层主要控制着该区域的黄金矿化。
 
径向基函数和克里格——金矿案例分析
D Kentwell, 2014

摘要:采矿软件的发展实现了连续(品位)和分类(地质)数据径向基函数(RBFs),算法为内插和外插。RBFs接近某种克里格——双克里格。Stewart等人(2014)在最近的一篇文章中详细描述了RBFs和克里格理论,并比较了采用负偏态分布(近似低品位铁矿)模拟数据集的估算结果。本案例中使用Leapfrog软件,RBFs在该软件中是主要的算法。本文在理论方面没有过多的描述,倾向于从实证方面来研究RBF估算,使用了真实的金矿数据集,勘探钻孔和品位控制钻孔数据集可供使用。该金矿分布为正偏态分布,与正或负偏态分布相比,在估算过程中带来更多的困难,分布的高品位尾矿影响了估算敏感性。
