PLC Resources Uncovers New Gold Target Corridor at Rochefort via High-Resolution Airborne Survey, Reports Promising Drilling Results

Encouraging Gold Anomalism Detected in Rochefort RC Drilling within Fractionated Dolerite Host Rock

PLC Resources' initial reconnaissance reverse circulation (RC) drilling at the Rochefort Gold Prospect has yielded results supporting the presence of a potential gold mineralised system near the drill area. Five RC holes (26ANRC001 to 26ANRC005) totaling 1,020 metres intersected sedimentary and mafic units, including highly fractionated dolerite identified previously by surface rock chip sampling. Three holes returned anomalous gold values up to 0.4 g/t Au, marking the first drilling at Rochefort within the Abbotts North Gold Project in Western Australia.

The geological context is significant, with dolerites in holes 26ANRC001, 26ANRC002, and 26ANRC005 showing strong fractionation consistent with dolerite units associated with major gold deposits in the Eastern Goldfields and Yilgarn region. Gold anomalism at Rochefort correlates with the super-fractionated unit near the bottom of hole 26ANRC005, confirming the prospective host rock. This supports the company's interpretation of a potentially larger gold system northwest of the current drilling area.

Pathfinder Geochemistry and Alteration Indicate Concealed Gold Mineralisation Northwest of Drilling

Multi-element geochemical analysis from Rochefort drill samples identified features indicative of proximity to a gold mineralising system. Increasing sodic (albite) alteration combined with magnesium depletion was observed in the northern drill area across holes 26ANRC001, 26ANRC002, and 26ANRC005. Weak but consistent sulphide development, interpreted as pyrrhotite, was also noted. These processes commonly associate with gold deposition in dolerite-hosted systems, reinforcing the interpretation of a nearby mineralised system.

Pathfinder element trends further support targeting, with sulphur increasing alongside gold while arsenic and antimony decrease, consistent with proximity to a gold source rather than distal geochemical signatures. Spatial analysis shows gold grades, though low with a peak of 0.4 g/t Au, systematically increase northwest and at depth in holes 26ANRC001, 26ANRC002, and 26ANRC003 within the most fractionated dolerite. These geochemical and spatial trends have prompted plans for follow-up RC drilling to test the strengthening trend and potential for a more substantial gold system northwest and deeper than current drilling.

Expanded Multi-Element Assays Planned to Enhance Targeting and System Understanding

The company is evaluating additional multi-element assays on a broader range of Rochefort drill samples to better understand the mineralisation system and strengthen confidence in the proximity interpretation. The timeline and specific elements targeted remain undisclosed.

Drill planning for follow-up RC drilling at Rochefort is underway and can proceed immediately under existing environmental and heritage approvals. This pre-approval enables PLC Resources to promptly initiate the next drilling phase once planning concludes. The combination of ongoing geochemical interpretation and advanced drill planning underscores Rochefort as a near-term exploration priority within the Abbotts North Gold Project.

High-Resolution Airborne Survey Discovers Major New Structural Gold Target on Eastern Abbotts Greenstone Belt Margin

Separately, PLC Resources' high-resolution airborne magnetic and radiometric survey uncovered a major new, entirely untested structural gold target corridor that has fundamentally altered the company's understanding of the Abbotts Greenstone Belt. The survey revealed a large syncline fold structure along the belt's eastern margin absent from existing Geological Survey of Western Australia (GSWA) regional maps. This new structural feature significantly enhances the company's exploration model for Abbotts North, providing a regional-scale target corridor framework.

The structural setting includes the syncline hinge intersecting a deep-seated east-west crustal feature linked to a younger Proterozoic dyke. This intersection is recognized across the Yilgarn Craton as a key control on high-grade orogenic gold mineralisation. The new regional target corridor lies along strike from New Murchison Gold (ASX:NMG) prospects such as Youngs and Lydia, and the Crown Prince deposit containing 2.2 million tonnes at 3.3 g/t Au for 228,400 ounces of gold.

Cross-Cutting Structural Corridor Extends Toward Historical Gold Prospects and Triple Junction

The survey also identified a cross-cutting structural corridor extending toward historical gold prospects within New Murchison Gold's tenements, offering a second regional target for PLC Resources' exploration. Programs of Work have been approved for regional aircore drilling targeting this corridor, with planning underway.

The Triple Junction Prospect, adjacent to the primary structural target, has exploration significance due to a previous high-grade gold rock chip sample of 6.7 g/t Au. This historical evidence, combined with the new structural data and proximity to major regional gold deposits, positions the eastern margin corridor as a substantial regional exploration opportunity.

Funding and Approvals Enable Swift Exploration Program Execution

Executive Director Simon Phillips confirmed PLC Resources is fully funded for follow-up drilling at Rochefort and the newly discovered regional syncline structure. Secured heritage and environmental approvals allow immediate commencement of drilling activities without typical regulatory delays. Programs of Work for regional aircore drilling targeting the cross-cutting corridor are also approved, with planning in progress.

This combination of full funding, regulatory approvals, and advanced drill planning equips Abbotts North with near-term exploration optionality. Mr. Phillips emphasized the clear discovery opportunities through Rochefort follow-up drilling and a growing pipeline of regional targets as geological interpretations evolve. The company is positioned to execute its exploration plans without additional capital requirements or extended regulatory wait times.

Strategic Location of Abbotts North Gold Project within the Yilgarn Craton

The Abbotts North Gold Project lies within the Yilgarn Craton, a premier global gold-bearing province hosting numerous major deposits and mining operations. Geological features identified at Abbotts North—highly fractionated dolerite hosts, albite alteration, sulphidation, and syncline structures—are directly associated with significant gold deposits in the Eastern Goldfields. These findings, combined with the airborne survey's structural framework, support the presence of material gold mineralisation near the project area.

Regionally, Abbotts North benefits from proximity to New Murchison Gold's prospects and the Crown Prince deposit, which hosts 2.2 million tonnes at 3.3 g/t Au for 228,400 ounces. Exploration success at Abbotts North would occur within a proven mineral resource development region with strong exploration precedent.

Exploration Risks and Uncertainties at Rochefort and Regional Targets

Current gold grades at Rochefort remain below economic thresholds, with a maximum of 0.4 g/t Au from reconnaissance drilling. The interpretation of a larger mineralised system relies on indirect evidence such as pathfinder geochemistry, alteration, and spatial trends rather than direct high-grade intersections. Follow-up drilling carries exploration risk that the mineralised system may be absent, deeper than planned, or economically unviable.

The newly identified regional target corridor, though structurally compelling, remains untested by drilling. Airborne survey data do not confirm gold mineralisation presence. The planned regional aircore drilling will be the first direct test, carrying inherent risks regarding mineralisation presence and economic significance. Exploration and development remain subject to permitting changes, heritage considerations, commodity price fluctuations, and geological uncertainties.

Technical and Operational Roadmap for Abbotts North Exploration

PLC Resources' exploration strategy includes near-term follow-up RC drilling at Rochefort to test northwest and down-dip extensions of the interpreted mineralised system. Pending additional multi-element assays will refine targeting and support drill planning. Medium-term plans involve regional aircore drilling targeting the syncline fold and cross-cutting structural corridors, with Programs of Work approved.

Integration of reconnaissance drilling results and high-resolution airborne data has expanded the company's geological model from Rochefort to a broader regional framework with multiple target corridors along strike from major gold deposits. Full funding and secured approvals establish a strong foundation for executing upcoming exploration phases. The company has outlined a clear, structured exploration pathway with defined near-term and regional drilling programs to test identified targets from current and historical work.
