Eminence Minerals Launches Major Drilling at Campo Grande Rare Earths Project

Drilling Campaign Marks New Exploration Phase

Eminence Minerals (ASX:EMA) has commenced a pivotal drilling program at its wholly owned Campo Grande Rare Earth Project in Bahia, Brazil. The campaign involves up to 72 auger drill holes spanning approximately 2,000 meters across three carefully selected priority corridors. This marks a significant escalation from previous surface sampling efforts, providing the first opportunity to test the subsurface extent and continuity of rare earth mineralisation on the property.

The project’s strategic positioning next to Brazilian Rare Earths’ (ASX:BRE) Sulista Project; an area that has yielded impressive drill results with grades up to 45.7% total rare earth oxides (TREO); adds a compelling regional context to Eminence’s exploration efforts. While proximity offers a favourable geological framework, Eminence cautions that mineralisation on adjacent tenements does not guarantee similar grades or continuity within its own tenure.

Broader Exploration Scope Beyond Priority Targets

Alongside the main drilling campaign, Eminence plans to test six additional regional scout targets identified through recent geological reinterpretations. These targets focus on newly interpreted clay alteration zones and rare earth element anomalies beyond the primary corridors. Concurrent surface sampling programs aim to expand geochemical coverage and refine future drill targeting across the broader Campo Grande area.

Drilling operations are being conducted by Eco Sondagem, a seasoned Brazilian contractor with a solid track record supporting mineral exploration projects nationwide. The company’s engagement of Eco Sondagem follows a recent contract award for the 2,000-meter campaign, underscoring Eminence’s commitment to executing a thorough and systematic exploration program.

CEO Highlights Project Potential in Emerging District

CEO Anthony Hills described the drilling commencement as a “significant milestone” for Eminence, signalling the start of an exciting new exploration phase. Hills emphasised that extensive geological interpretation had defined multiple high-priority targets warranting drill testing, with this maiden program providing the first subsurface assessment of these targets’ scale and continuity.

He also highlighted Campo Grande’s location within the rapidly developing Bahia rare earth district as a key factor underpinning the project’s prospectivity. Previous reconnaissance sampling by Eminence has returned assays up to 17,346 parts per million TREO (approximately 20% middle rare earth oxides), reinforcing the potential for meaningful discoveries.

Next Steps and Market Implications

With drilling now underway, the market will be watching for initial assay results and geological data releases that could validate the presence of significant rare earth mineralisation. The campaign’s outcomes will be critical in shaping Eminence’s resource definition and future development plans within this emerging rare earth district.

Given the strategic adjacency to Brazilian Rare Earths’ Sulista Project and the broader sector interest in rare earth elements amid global supply chain shifts, Campo Grande’s exploration progress could influence Eminence’s valuation and investor sentiment. However, as the company notes, the success of exploration remains uncertain until drilling results confirm mineralisation characteristics.
