Capricorn Metals has released a detailed technical report outlining robust drilling, sampling, and estimation techniques at its Mt Gibson Gold Project. The comprehensive JORC Code Appendix supports high-confidence mineral resource estimates, strengthening the company’s exploration outlook and potential for future growth in the gold sector.

The released JORC Code document provides a detailed account of the technical procedures, quality controls, and estimation methods used to report the mineral resource at the MGGP. The report explains that all sampling—from reverse circulation (RC), diamond (DD), and aircore (AC) drilling—is conducted with industry‐accepted techniques, including the use of calibrated equipment, duplicate sampling, and the insertion of certified reference materials. For instance, RC samples are split from one‐meter drill intervals and processed using a standard fire assay method, while diamond drill core is cut and logged both visually and photographically to capture key geological features such as lithology, weathering, and mineralisation. Historical drilling data also play a role in validating the current resource model, despite some uncertainties about earlier methods. In addition, the document describes how drillhole locations are recorded with GPS and consolidated using a standard grid system to ensure high data accuracy. The technical narrative outlines how the geological observations have been used to build a robust three-dimensional model of the deposit – incorporating geological interpretations, weathering profiles and structural controls – which then guides the grade estimation process. Mineral resource estimation relies on Ordinary Kriging techniques performed in several passes with defined search parameters and block sizes optimized for the deposit’s geometry. A series of cut-off grades are applied: for example, the open pit resource is reported at cut-offs of 0.4 or 0.5 g/t Au, while a higher cut-off of 1.5 g/t is used for the underground component to ensure that only material with sufficient continuity is considered economic. The estimation process is reinforced by in-house data validation and independent cross-checks, with the overall classification of the resource reflecting the confidence based on drilling density and geological continuity. Furthermore, the report emphasizes that tonnages are estimated on a dry basis using measured bulk density values that are typical of Archean greenstone deposits. While the document covers all elements necessary to provide a transparent and balanced technical report, it also clearly states that no Ore Reserve is being reported at this stage – only the Mineral Resource estimate is included. For investors and beginner traders, this level of technical disclosure is intended to demonstrate that the project has been subject to rigorous exploration, sampling, and resource modelling in line with internationally recognised standards, thereby supporting the potential for future development while acknowledging that many aspects – such as mine planning, recovery assumptions, and future economic factors – will need to be further refined as the project advances.
