Impact Minerals (ASX: IPT) has unveiled a significant 4km gold-silver structural corridor at its Commonwealth project, with a maiden drill program imminent, while also detailing progress on its Lake Hope HPA project.
The dual announcements highlight the company's advancing exploration and development efforts.
Commonwealth Gold-Silver Corridor Defined
A 4km NNW-SSE structural corridor linking Commonwealth Mine, Silica Hill, and adjacent prospects has been identified by MobileMT EM.
3D resistivity modelling shows continuous controls to depths exceeding 1km, indicating potential for mineralisation extensions.
A maiden 1,200m diamond drill program is scheduled to commence imminently to test these targets.
Impact retains a 30% free-carried interest under its JV with Kuniko, mitigating near-term funding risk for this exploration.
Lake Hope HPA Project Advances
The Pre-Feasibility Study confirms Lake Hope as a globally significant High Purity Alumina (HPA) project with robust economics (NPV10 A$1.165B, IRR 47.5%).
Progress continues with Definitive Feasibility Study (DFS) commencement, pilot plant development funded by a CRC-P grant, and ongoing off-take discussions.
Strategic acquisitions have increased ownership in Playa One (80%) and Alluminous (50%), bolstering processing technology and market access.
SOP-HCl Opportunity Identified
A new, standalone pathway to produce Sulphate of Potash (SOP) and Hydrochloric Acid (HCl) from lake clays has been identified.
Lab results show high recoveries for SOP (K2O ~94%, SO3 ~94%) and chlorine (>98%), with potential to capture HCl.
A Scoping Study is underway, with results expected in Q2 2026, to define costs and scale for this potential new revenue stream.
Broken Hill Exploration Resumes
Exploration has resumed at Broken Hill, focusing on PGMs, silver-lead-zinc, and copper mineralisation styles.
Recent drilling (PSD02) returned a high-grade intercept of 0.6m at 7.6% Cu, 7.4% Ni, plus multi-PGE/metals.
Three new channels have been identified at Plat Central/East, with ground EM planned ahead of further drilling.
Dual-pronged Strategy Fuels Upside
Impact Minerals is progressing on two significant fronts: unlocking exploration potential at Commonwealth with imminent drilling and advancing its Lake Hope HPA project through DFS and pilot plant development.
The addition of a potential standalone SOP/HCl project and ongoing exploration success at Broken Hill add further layers of potential value creation.
