The aim of this seminar was to make the presentations as practical aspossible and therefore the seminar program was built around case studiesprovided by mining and exploration groups actively working in the CentralWestern NSW area. The seminar was broken into two sessions each with a specifictheme:1. The transition from project to mining - the evolving resourceestimate; and 2. Using domains to constrain resource estimates - pitfallsand windfalls. Group discussions followed the presentations of casestudies in both sessions and these discussions are reproduced in the volume.Contents include: Evolution of Resource and Reserve Estimation Methods atPasminco Broken Hill Mine Southern Underground Operations; Why feasibilityResource Estimates Under-valued the Peak Orebody; Tritton Copper ProjectResource Estimation - The Inter-relationship of Geology Structure and Kriging; Ore Reserve/Resource Estimation Methodologies at Elura Mine; Cadia Hill - FromDiscovery to a Mine - A Case Study; Resource Estimation at Northparkes MinesNSW; Grade Domains Versus Geological Domains at the Browns Creek Gold Mine NSW; How Geological Envelopes Impact on the Resource Estimate - A Case Study of Advanced Projects in the Cobar Gold Field; and Busangs Red Flags and the Canadian Response.
