Besra Gold Inc. Announces A Revised JORC Compliant Mineral Resource Estimate (MRE) for the Jugan Gold Project
Besra Gold Project announced that Completion of a revised, independent Mineral Resource Estimate (MRE) of the Jugan Project marks a significant step forward in the project's feasibility development. The revised MRE totals 13.5 million tonnes @ 1.7 g/t Au for 721k oz comprising: Measured: 209k oz. It is imperative that proposal recognises that both community expectations and physical conditions have changed considerably since the 2012 feasibility study was completed. That study adopted a large-scale open pit and adjacent wet tailings facility, which by today's standards is considered inappropriate land usage of strategic portions of the Sarawak River floodplain and adjoining catchment area. With the revised Jugan MRE completed, the next steps will include the completion of geo-technical drilling (expected by June 2025), the appointment of a Bankable Feasibility Study Manager, BSF level metallurgical test work with samples already enroute to a Perth laboratory and mobilisation of an RC rig to Jugan for hydrogeological test work. Widenbar considers the database used represents an accurate record of the drilling undertaken at the project. Drill hole location plots have been used to ensure that local drill spacing conforms to the minimum expected for the relevant resource classification. Historic data was stored in various databases and has been transferred to the Besra database and validated., Drill hole data was provided to Widenbar in CSV format and imported into Micromine 2025 software., All drill hole data was validated in Micromine 2025 after import, including: Checks for duplicate collars, Checks for missing samples, Checks for down hole from-to interval consistency, Checks for overlapping samples, Checks for samples beyond hole depth, Site visits, Comment on any site visits undertaken by the Competent Person and the outcome of those visits., If no site visits have been undertaken indicate why this is the case., The Competent Person has not made a site visit., Besra Gold staff who have acted as Competent person for previous Resource Estimates have conducted site visits on multiple occasions and provided Widenbar with: Multiple geological reports, Previous supporting MREs, Besra Gold Project - Feasibility Report, 2013, Core photos from the 2021-2022 drill campaign, Aerial photography of the Jugan deposit, Site photos showing drilling and trenching activities, Associated quality assurance and quality control (QAQC) reporting from the 2021-2024 drill campaign., Competent Person does not identify any risks as result of not undertaking a site visit., Geological interpretation, Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit., Nature of the data used and of any assumptions made., The effect, if any, of alternative interpretations on Mineral Resource estimation., The use of geology in guiding and controlling Mineral Resource estimation., The factors affecting continuity both of grade and geology., The Jugan deposit is a mature discovery, first discovered in the 1900s and worked for alluvial gold.athering surfaces are soft boundaries., The estimation process uses dynamic anisotropy to orient the search ellipse according to the varying dip and strike of the mineralised domain, Criteria, JORC Code explanation, commentary, Discussion of basis for using or not using grade cutting or capping., The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available., The estimation process was validated by comparing global block grades with the average composite grades, visual checks comparing block grades with raw assay data and swathe plots. All methods showed good correlation between drill data and block model., Moisture, Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content., All tonnages are estimated on an dry basis and moisture content is not considered in the resource estimate., Cut-off parameters, The basis of the adopted cut-off grade(s) or quality parameters applied., Current costs and prices for open pit and underground mining provided by Besra, and used to determine cutoffs. Where this is the metallurgical assumptions made., Historical metallurgical testwork and studies that focus on the Jugan deposit have been compiled in six previous metallurgical reports: Historical metallurgical reports: Historical meetallurgical testwork and studies.
