摘要
矿业公司的成功取决于资源数据库的完整性。只有在实施了适当的采样和分析方案后，才能保证分析数据的质量，从而保证数据库的有效性。有必要使投资者和项目出资人相信，已经收集了适当的样本，分析是有效的。监测实验室数据提高了公司对矿石储量、钻探目标选择和管理的信心。这项工作考察了取样、分析和质量保证因素对项目成功的影响，并分析了金星资源(Prestea/Bogoso)有限公司的样品。它描述了Fire assay和Screen Fire assay，这是一种“高科技”的黄金分析方法。研究表明，筛火法是一种比火法更适合和可靠的分析粗粒金矿石的方法。因此，建议将筛火试验方法作为金矿勘探的一般模式，特别是对于含粗金问题的矿石。
Assessment of Quality of Assay Data on Drill Samples from Golden Star Resources (Prestea/Bogoso)Ltd
The success of a mining company is dependent on the integrity of the resource database. The quality of assay data and thus the validity of the database can only be guaranteed when appropriate sampling and assaying protocols have been implemented. It is necessary to convince investors and project financiers that appropriate samples have been collected and that analyses are valid. Monitoring laboratory data improves confidence in ore reserves, drill target selection and management of the company. This work examines how the key sampling, analytical and quality assurance factors impact on project success and assaying samples from Golden Star Resources (Prestea/Bogoso) Limited. It describes Fire assay and Screen Fire Assay, a ‘high tech’ method for gold analysis. The study has shown that Screen Fire Assay is a more suitable and reliable analytical method for ores with coarse gold particles than fire assay. It is therefore recommended that the Screen Fire Assay method be used as a model for gold exploration in general and for ores with coarse gold problems in particular.
