Drilling Milestone at Rochefort
PLC Resources has finished an eight-hole, 1,896-metre reverse-circulation (RC) drilling program at its Rochefort gold prospect in Western Australia’s Murchison region. The campaign was designed to step out from a maiden five-hole program earlier in the year and to intersect the “fractionated dolerite” target that the company believes hosts gold-bearing sulphidation zones. Early geological logging confirmed the drill bits passed through sheared sulphide-bearing intervals and magnetite-bearing layers that match the firm’s exploration model, which draws on the sulphidation processes that underpin major Yilgarn deposits such as the Golden Mile Dolerite of the Kalgoorlie Super Pit. All core samples have been sent to a laboratory, with assay results expected within four to six weeks.
Exploration Model and Regional Context
PLC’s model posits that mineralising fluids altered primary sulphides (e.g., pyrrhotite) into pyrite within iron-rich dolerite, potentially precipitating gold. The recent airborne magnetic survey over the broader Abbotts Greenstone Belt revealed a 14-kilometre-long fold structure along its eastern margin. Management describes the feature as a crustal-level corridor that extends into ground held by New Murchison Gold, a $750 million market-capped peer that recently generated over $50 million in cash flow from high-grade discoveries and toll-treatment operations. PLC plans geological reconnaissance next month to ground-truth the newly identified structural corridors before launching a regional air-core drilling campaign on untested targets.
Official Statements & Responses
He emphasized that while the visual results are encouraging, definitive conclusions await the forthcoming assay data.
Key Data
- Drilling: 8 holes, 1,896 m total depth
- Target: fractionated dolerite with sulphidation potential
- Survey: high-resolution magnetic data, 14 km fold structure
- Nearby peer: New Murchison Gold, $750 million market cap, $50 million Q3 cash flow
Potential Impact
If assays confirm gold mineralisation, Rochefort could represent a new virgin gold system. Coupled with the larger structural corridor shared with a profitable neighbour, PLC Resources may have two independent pathways to uncover additional gold deposits, potentially strengthening its position in the emerging Murchison gold district.
Verbatim Quotes
- “We’ve now completed our follow-up drilling at Rochefort, and the logging shows the geology we set out to find: sheared, sulphide-bearing zones within the fractionated dolerite. That’s encouraging, but the assay results are required to determine whether the system is mineralised with gold. We expect those results within the next four to six weeks.” — Simon Phillips, PLC resources executive
