Regis Resources Limited has released an extensive update on its exploration and resource estimates across key projects, highlighting robust drilling results and improved mine planning. The announcement supports a positive long-term outlook, reinforcing the company’s growth potential and value creation for shareholders.
This announcement is a comprehensive technical report outlining exploration, sampling, data management, and resource estimation procedures at several of the company’s gold projects, prepared in accordance with JORC Code 2012 guidelines. Detailed information is provided on the sampling techniques used across different drilling methods—including air core (AC), reverse circulation (RC), and diamond drilling (DD) – with explicit procedures for sub‑sampling, sample preparation, and laboratory assay protocols. The report explains in depth how quality control is maintained by the insertion of blanks, standards, field and laboratory duplicates, and via regular assessments of sample recovery and consistency.
The document covers projects such as Duketon, Garden Well, Tropicana (including a joint venture exploration component), and Rosemont. For each project, it presents extensive data on drilling orientations, spacing, and methodology, together with strict procedures for logging, digital data capture, and validation through systems like LogChief™, Datashed, and Geobank. Drill hole information and numerous intersection results with specific gold grade values and lengths are provided to demonstrate the continuity and grade distribution, ensuring that reported grades reflect true thicknesses of the mineralised zones.
Resource estimation for both Mineral Resources and corresponding Ore Reserves is described in detail. The report outlines the use of Ordinary Kriging (OK) and specific block modelling parameters, including block dimensions, search ellipsoids, and the application of grade cuts to minimize the impact of high-grade outliers. The conversion process from Mineral Resources to Ore Reserves is supported by comprehensive mine design, stability assessments, and economic studies that factor in mining dilution, recovery rates, metallurgical test work, operating costs, and revenue assumptions such as gold price, royalties, and processing expenses.
In addition to the technical details, the report confirms robust data integrity and assurance through routine audits, field quality control reviews, and independent verifications. Project tenement and land tenure information is provided alongside details of exploration histories, stakeholder agreements, and environmental considerations. Overall, the announcement demonstrates a rigorous and transparent approach to resource estimation and ore reserve reporting, ensuring that the company’s assets are evaluated with high confidence and in compliance with internationally recognized industry standards.
