Tungsten Mining NL’s review of historic drilling at Mt Mulgine shows promising near‐surface oxide gold intercepts that may offset pre-stripping costs and improve project economics. Infill drilling is planned to better define these targets, strengthening the resource’s potential amid a favorable commodity market.

Tungsten Mining NL has released an extensive technical report outlining its compliance with the JORC Code reporting criteria for the Mulgine Trench prospect. The document covers a detailed review of historical and recent exploration programs that span from the 1970s through 2015. Multiple companies have drilled over 1,000 reverse circulation holes, RAB holes, and diamond drillholes in the area, targeting tungsten, molybdenum, gold, silver, and copper mineralisation. The report explains the range of drilling techniques employed over the years—from diamond drilling using NQ and BQ cores to modern reverse circulation methods—and documents the evolution of sampling practices, which now include rigorous use of cone and riffle splitters, multiple composite lengths, and quality assurance measures that are benchmarked against industry standards. The announcement provides a comprehensive record of sampling techniques, including sample collection, processing, and assaying procedures. Detailed commentary is offered on quality control measures such as the insertion of field standards and duplicate samples, the use of DGPS and gyroscopic systems for drillhole collaring and downhole surveying, and extensive geological logging procedures. The report shows that older data from early exploration programmes have been incorporated, re-evaluated, and cross-checked through modern QAQC procedures. Additionally, the document highlights that all drillhole locations and assay data have been carefully converted to contemporary grid standards to ensure accurate spatial control in resource modelling. From a geological perspective, the Mulgine Trench deposit is described as a large, low-grade multi-metallic resource hosted in a complex suite of altered and metamorphosed volcanic and intrusive rocks. The report details the characteristics of several key targets within the prospect—the Trench, Black Dog, Bobby McGee, and Highland Chief deposits—each exhibiting significant supergene enriched zones that have effectively upgraded the gold mineralisation. These fronts are structurally controlled, with mineralised zones intersected at angles that have been carefully adjusted over successive drilling phases to improve representativity. Looking ahead, Tungsten Mining NL is planning further pattern drilling of the oxide gold targets and intends to complete a Mineral Resource estimate as well as a comprehensive integrated scoping study. This forward program is designed to evaluate the near-term potential of a start-up oxide gold project and its strategic alignment with the broader Mt Mulgine Tungsten Project. The comprehensive review and methodical documentation of exploration procedures carry a bullish tone for the company from a technical standpoint. The rigorous quality control, substantial historical data, and planned follow-up work suggest that management is committed to unlocking value in these complex deposits. However, beginner traders should note that while the technical foundation is strong, the development stage and the need for infill drilling in some areas might translate into timing and resource expansion risks typical of early-stage resource projects.
