Latest Geological Modeling News

Catalyst Metals has converted the Cinnamon underground discovery into a maiden 232koz Ore Reserve, supporting a 7.5-year mine plan at the Plutonic Gold Belt. The deposit’s total Resource has grown 370% to 541koz, although part of the production target still relies on Inferred material.

Pursuit Minerals has started its first diamond hole at the Demasía tenement, testing whether lithium-bearing brines extend beyond the existing 1.264 million tonne LCE resource at Rio Grande Sur. Early packer tests recovered brine at shallow depths, but lithium assays are still pending.

CGN Resources has expanded its exploration footprint across gold and copper, but the annual report pairs that growth with a material going-concern uncertainty. The company ended FY2026 with $2.11 million in cash against $1.99 million of operating cash outflows.

Sunstone Metals has expanded its Bramaderos gold-equivalent resource to 3.6Moz and reported new Porotillo and Copete discoveries, but its FY2026 accounts carry a material uncertainty over going concern. A post-year-end A$9.94 million placement has improved liquidity, although further equity funding remains central to the exploration plan.

New Hope Corporation Limited (ASX:NHC) has lifted its reported coal resources to 2.96 billion tonnes, driven by major model updates at Bengalla and New Acland. The larger inventory comes with important qualifications: much of Bengalla’s addition is inferred, while a substantial portion of New Acland’s reserves still depends on future approvals.

Magnum Mining has completed more than 10,000 metres of drilling at its Piracanjuba North rare earths project in Brazil and is shifting its main effort to the 32.5km² Plateau Zone. A further 2,000-metre diamond drilling phase will run alongside independent resource, radiological and metallurgical studies, although delayed assay turnaround creates a risk to the company’s November timetable.

Forrestania Resources has reported wide, high-grade gold intersections from 15 additional reverse circulation holes at British Hill in Western Australia. A diamond rig is now being mobilised to test below current RC drilling limits as the company works towards a larger mineral resource estimate.

Maronan Metals has reported broad and high-grade silver-lead intersections from its ongoing 40,000-metre infill program, including 11 metres at 10.3% lead and 116g/t silver. More than 15,000 metres have now been completed, with results feeding a planned 2027 resource update and pre-feasibility study.

Legacy Minerals has appointed WSP to assess scandium at its 100%-owned NiCo Young project, potentially adding a third critical mineral to a 167.8Mt inferred nickel-cobalt resource. The combined JORC update is expected in October, but no scandium resource has yet been established.

Prospect Resources has expanded drilling at Nyungu Central after returning a 27-metre copper intercept outside the existing resource, while maiden drilling at Sharamba confirms a new copper discovery. The results add momentum to Mumbezhi’s growth story, but most Phase 3 assays remain outstanding and no resource update has yet been made.

Sentinel Metals has reported broad, stacked gold mineralisation at its Columbia project in Montana, including a 48-metre intercept at 1.13g/t gold. Fire assays have also confirmed the company’s earlier high-grade maiden-hole result, while a November resource update now looms as the key test.

Corazon Mining has begun a 50-hole, approximately 7,500-metre RC drilling program at its Chalice Gold Project in Western Australia. The campaign will test near-surface extensions to the existing 191,000-ounce resource, while the company cautions that its larger 830,000-ounce Exploration Target remains conceptual.
