GreenTech Metals Limited has released a JORC Code report outlining exploration and sampling techniques on its Whundo, Ayshia, and Yannery projects. The document details drilling methods, sample preparation, quality control, and data verification, and notes upcoming further drilling, metallurgical tests, and a conceptual mine study for near‐term production.

GreenTech Metals Limited has released an extensive technical report prepared in line with the 2012 JORC Code framework. The document details the company’s rigorous approach to exploration in the Whundo–Ayshia region. It covers the sampling techniques, drilling approaches and assay procedures applied during the exploratory campaign. The report explains how both reverse circulation (RC) and diamond drilling were deployed, with modern core handling methods and use of high‐grade quality control measures to ensure representative sampling. The company outlines the use of specialized equipment—including rig‐mounted cyclones, static cone splitters, and core orientation tools—and emphasizes that recent drill holes were logged, processed, and analyzed through established laboratory techniques. The report describes the methods used for sub-sampling and preparation, indicating that the mineralised sections from diamond drilled core were sawn and quartered appropriately, while RC drill samples were collected at one-metre intervals. Laboratory work at a well-regarded facility included 50-gram fire assays for gold and multi-element analysis using four acid digestion with ICP techniques. These procedures, coupled with duplicates, blanks, and certified reference samples, are presented as evidence of the company’s commitment to robust quality assurance and quality control protocols. In addition to technical sampling and processing details, the announcement reviews ancillary exploration data. It provides information on the tenement status, noting that drilling is conducted on mining licences in an area with a long history of exploration and small-scale mining. The regional geology is described as hosting volcanogenic massive sulphide (VMS) style copper–zinc–cobalt deposits hosted within Archaean greenstones—a setting that reinforces the company’s focus and supports its future resource estimates. Looking ahead, the company is advancing plans for a conceptual mine study and further drilling programs. These future activities include testing the lateral continuity of mineralisation between known areas, evaluating additional targets such as the shallow high-grade oxide mineralisation at Yannery, and obtaining material for metallurgical tests. GreenTech Metals Limited also intends to assess processing options at nearby facilities and has initiated the mining permit application process. From a market sentiment perspective, the report is bullish in that it demonstrates a comprehensive, cautiously optimistic approach toward de-risking its exploration potential. The detailed description of modern sampling, drilling, and laboratory protocols supports confidence in the company’s technical rigor. However, there is also a degree of bearish caution as much of the reported data comes from exploratory drill holes that have not yet been fully validated for resource estimation, and some historic data records are less comprehensive. Overall, while the initiative signifies a strong technical foundation for future resource development, significant further exploration is required before the full economic potential of the deposit can be confirmed.
