Optimizing Drilling Spacing for Mineral Exploration: Best Practices and JORC Compliance Core drilling for dipping mineral deposits Introduction  In the field of mineral exploration, one of the critical steps towards accurately defining a mineral deposit and resource is the implementation of an efficient drilling program. The success of this program hinges on meticulous planning and adherence to industry standards such as the JORC Code (Joint Ore Reserves Committee Code). The JORC Code itself does not prescribe specific drilling spacings for different types of minerals. Instead, it provides principles and guidelines for reporting exploration results, mineral resources, and ore reserves, emphasizing transparency, materiality, and competence. However, industry practices have established typical drilling spacings for different types of minerals based on experience and geological considerations. This article highlights into best practices for drilling spacing across various minerals. ...

The Influence of Geological Structures on Gold Deposits: Faults, Shear Zones, and Folds

Image
The Influence of Geological Structures on Gold Deposits: Faults, Shear Zones, and Folds 1. Introduction Gold mineralization is a complex process influenced by a multitude of geological factors, among which structural controls play a pivotal role. This article, based on experiences of Dr. Vinay Sahay in gold exploration, presents the various structural settings that influence gold deposit formation, including fault zones, shear zones, and fold systems. By examining these structures, the mechanisms of gold transport and deposition can be better understood, providing valuable insights for exploration and mining. This article highlights key examples from Archean greenstone belts, mesothermal/orogenic gold deposits, and epithermal gold systems, illustrating the diverse structural environments that host significant gold mineralization. 2. Geological Setting Gold deposits occur in various geological settings, each characterized by specific structural features. These include orogenic...

Application of Six Sigma in the Environmental Clearance Process of Mining Projects in India

Image
Application of Six Sigma in the Environmental Clearance Process of Mining Projects in India Introduction The mining industry in India is a critical sector contributing to economic growth. However, environmental clearance (EC) processes for mining projects in India are often lengthy and complex, leading to significant project delays and increased costs. Six Sigma, a data-driven approach for process improvement, offers potential solutions to streamline these procedures, enhance compliance, and minimize environmental impact. This study led by Dr. Vinay Sahay examines how Six Sigma methodologies can be applied to optimize the EC process, making it more efficient and effective. Six Sigma Overview Six Sigma is a systematic approach to process improvement that helps to minimize defects and variability. It employs two primary methodologies: DMAIC (Define, Measure, Analyze, Improve, Control) for improving existing processes and DMADV (Define, Measure, Analyze, Design, Verify) for creati...
