Everyday Drill Hole Spacing Analysis - Optimal Spacing for Mineral Resource Estimation

Explore a comprehensive conference talk on Everyday Drill Hole Spacing Analysis (DHSA) presented by Jane Levett, Principal Consultant at Snowden Optiro, during the Geology Symposium 2022. Gain insights into the geostatistical processes used to assess estimation quality for drill spacing, informing drill programme requirements and supporting Mineral Resource Classification. Learn about various DHSA approaches, including estimation quality, production-linked, and simulation methods. Discover the application of DHSA to Mineral Resource classification and its limitations. Follow along as Jane demonstrates everyday DHSA using Snowden Supervisor software and presents a case study on the Wilconi Nickel Cobalt Laterite project. Enhance your understanding of this crucial tool for resource development and grade control in the mining industry.
