King River Launches 11,000-metre Phase-Two Drilling Campaign at Mindoolah
By Drooid · · How we work
Core Event
King River Resources, an ASX-listed explorer, began an 11,082-metre reverse-circulation (RC) drilling program at its Mindoolah gold project in Western Australia’s Murchison region on October 12, 2026. The campaign targets eight priority zones — the Excelsior, Excelsior Repeat and Demagnetised Targets, plus several structural and intrusive prospects — and marks a shift from early reconnaissance to systematic testing of corridors believed to host significant gold mineralisation.
Project History and Prior Results
Phase-one drilling earlier this year achieved a 79 % hit rate, confirming shallow, high-grade mineralisation. Highlights include a 1 m intercept grading 13.59 g/t gold from 43 m at the Bertram’s prospect and a 3 m section at Le Soleil returning 4.7 g/t gold from 38 m, with a 1 m slice at 10.7 g/t. Official mining records list 38,589 tonnes extracted from the historic open pit in the 1980s, but King River’s calculations suggest the pit void contains about 1.08 million tonnes, implying additional ore may remain.
Data & Statistics
- Total RC length: 11,082 m
- Excelsior target: 3,252 m drilling, depths up to 354 m; previous drill intersected 4 m at 9.3 g/t.
- Excelsior Repeat: 1,710 m, a structural analogue with no prior mining.
- Demagnetised Target: 3,150 m, a magnetic depletion zone west of Le Soleil.
- Additional targets: 780 m at Mindoolah Main Reef (mafic dyke, 1.15 g/t surface sample), 630 m at Cundy fold hinge, 360 m at Double Barrel/More Pork (8.11 g/t surface sample).
- Financial position: $3.67 million cash as of end-June; retains 77 million Tivan Limited shares valued at $13.5 million.
Official Statements & Responses
He noted that phase-one delivered the subsurface data needed to build a robust geological model and that the company is entering a “catalyst-rich period.” Gadsby also indicated that a high-resolution aeromagnetic survey will launch alongside drilling, with results to be integrated with mapping, geochemistry and the new drill data.
Verbatim Quotes
- “Commencing this 11,082m Phase-two RC campaign marks a major milestone for Mindoolah, representing our largest targeted drilling program to date at Mindoolah. Phase-one achieved its core objective, confirming shallow gold mineralisation beneath historical workings while providing the subsurface data required to build a robust geological model.” — Graham Gadsby, resources managing director
