Key Highlights

  • Geo Spectra Pty Ltd's integrated multi-spectral, magnetic and geochemical analysis has defined priority gold targets across the Abbotts Gold Project in Western Australia's Murchison region
  • First-priority targets confirmed at Rochefort, Buttamiah, Vranizan North and Sprigg Bore based on coincident alteration, structural and geochemical vectors
  • Survey utilised EnMAP hyperspectral satellite imagery across approximately 205 km² covering four tenements, identifying alteration signatures similar to the nearby Crown Prince Gold Mine
  • Regulatory approvals are in place for aircore drill testing; field verification of first-priority targets is planned to commence during the current quarter, ahead of aircore drilling targeted for Q1 2027

PLC Resources Limited (ASX:PLC) has taken a significant step in defining the exploration priority at its Abbotts Gold Project, receiving results from a geo-spectral survey that for the first time provides a district-scale picture of gold potential across the company's ground in Western Australia's Murchison region.

The study was completed by Remote Sensing specialists Geo Spectra Pty Ltd and used EnMAP hyperspectral satellite imagery to cover approximately 205 km² across the Project's four tenements, located approximately 35 km north of Meekatharra. The programme was designed to identify alteration mineral assemblages and structural controls commonly associated with orogenic gold mineral systems throughout the Murchison region — a greenstone belt that has been a productive gold-producing environment in Western Australia for more than a century.

Results were delivered ahead of the four to six week timeframe flagged at the time of commissioning. Geo Spectra's analysis identified spectral signatures similar to those observed at NMG's producing Crown Prince Gold Mine, located approximately 5 km south of the Project. These signatures cluster predominantly within PLC's central tenement (E51/2126), near the eastern Margin of the greenstone belt along the eastern limb of the fold identified in the company's high-resolution magnetics data. A prominent cluster was also identified in the southeast corner of tenement E51/2130, coincident with historical rock-chip samples returning 651 ppb gold and 350 ppb gold.

Multi-Disciplinary Target Generation

The targeting methodology applied by Geo Spectra integrates three data streams: EnMAP hyperspectral alteration mapping, Sentinel-2A and ASTER-derived iron oxide and silica indices, and structural interpretation from magnetic survey data cross-referenced with the company's historical gold, copper and arsenic geochemistry. This multi-disciplinary approach is designed to reduce the risk of chasing single-vector anomalies that may not represent genuine mineralised systems.

Four first-priority targets have been confirmed: Rochefort, Buttamiah, Vranizan North and Sprigg Bore. All four display coincident alteration, structural and geochemical vectors — the combination that exploration geologists regard as the most reliable indicator of hydrothermal mineralisation in this style of deposit. An aircore drill-testing programme for these targets has regulatory approvals in place, with field verification planned to commence during the current quarter.

Rochefort Assays Pending

PLC also recently completed an eight-hole, 1,896-metre RC drilling programme at the Rochefort prospect, which has been the company's primary focus area. Assays from that programme remain pending and are expected in the coming weeks. Once received, these results will be integrated with the ranked geo-spectral targets to refine the drill-testing pipeline. Rochefort's significance is elevated by its proximity to the Crown Prince Gold Mine and by the alteration signatures identified in the satellite data.

Executive Director Simon Phillips described the survey as providing a defensible, ranked set of targets extending well beyond Rochefort across a string of prospects along the greenstone belt.

Sector Context

The Murchison region of Western Australia has a long history of gold production, with operating mines providing geological analogues for smaller explorers operating along the same greenstone belts. Growing use of satellite-based hyperspectral tools such as EnMAP — launched by the German Aerospace Center — has opened new efficiencies in target generation, allowing companies to survey large land packages in less time and at lower cost than ground-based programmes. PLC's approach of combining satellite alteration mapping with existing magnetics and geochemistry reflects broader industry practice among ASX-listed junior gold explorers seeking to prioritise drill targets before committing to field campaigns.

Risks

Geo-spectral surveys define vectors toward potential mineralisation; they are not confirmation of economic gold deposits. Assay results from both the pending Rochefort RC programme and future aircore drilling will be the critical test of whether the identified targets convert to genuine mineral inventory. Murchison gold projects frequently encounter structural complexity that makes geological interpretation challenging, and historical geochemical anomalies do not guarantee the presence of a continuous, drill-able deposit.

What to Watch Next

Near-term catalysts include the release of assays from the eight-hole Rochefort RC programme, which will provide the first quantitative test of the geo-spectral targeting model. Field verification of first-priority targets is planned to commence in the current quarter, followed by aircore drilling in Q1 2027. Successful results from either programme could accelerate the exploration timeline and provide a clearer picture of the scale of gold mineralisation across the Abbotts tenement package.
