New Murchison Gold Extends High-Grade Gold Mineralisation at Crown Prince East Pit

High-Grade Gold Confirmed at Satellite Crown Prince East Pit

New Murchison Gold Limited (ASX:NMG) has revealed robust results from its latest reverse circulation (RC) drilling at the Crown Prince East Pit, a satellite deposit located just 300 metres east of the active Crown Prince West Pit within its Garden Gully Gold Project in Western Australia. The drilling has delineated significant high-grade gold mineralisation within the pit's designed outline, with standout intersections including 18 metres at 10.3 grams per tonne (g/t) gold from 54 metres depth, featuring a 6-metre segment at an exceptional 29.3 g/t Au.

Drilling Campaign and Geological Insights

The recent program comprised 49 RC holes and two diamond core holes totaling 5,365 metres, aimed at testing subparallel southerly dipping lodes hosted in a mafic unit of foliated basalt and dolerite. These lodes contain gold mineralisation in quartz carbonate veins. The diamond holes provided structural data, confirming two distinct orientations of mineralisation: an east-northeast striking, southerly dipping set of lodes at approximately 50 degrees, and a steeper, discrete north-south striking zone. The intersection of these orientations corresponds to zones of particularly strong gold mineralisation.

This geological complexity adds nuance to the resource potential, with the high-grade shoots likely representing steep plunging ore shoots. The program's comprehensive assay data, including intervals such as 12 metres at 10.3 g/t Au and 9 metres at 5.3 g/t Au, reinforce the prospectivity of the Crown Prince East area as a valuable extension to the existing operation.

Advancing Towards Mining and Resource Integration

Importantly, Crown Prince East is already included within the Crown Prince Mining Approval, smoothing the pathway for rapid development. New Murchison plans to update its mineralisation modelling and integrate these new results into a JORC-compliant resource model, followed by a redesign of the pit outline to reflect the expanded mineral footprint. Preparations for mining commencement are underway, including potential sourcing of additional mining equipment.

These developments build on New Murchison's recent operational momentum, following a strong production quarter at Crown Prince Gold Mine earlier this year, where the company delivered 22,766 ounces of gold and maintained a solid cash position of $92 million. The new drilling results at Crown Prince East complement earlier high-grade discoveries at the nearby Lydia Prospect, underscoring the growing resource base within the Garden Gully tenure package and the company's advancing production profile.

Technical Rigor and Balanced Reporting

The drilling and sampling methodology adheres to industry best practice, with RC samples collected at one-metre intervals and analysed via 50g fire assay at certified laboratories. Quality control measures include duplicate sampling, certified reference materials, and blanks, with no evidence of sampling bias reported. Drill hole locations were surveyed with differential GPS and gyro tools, ensuring precise spatial control. While true widths of mineralisation are not yet fully defined, the downhole intercepts provide a reliable indication of high-grade zones warranting further delineation.

New Murchison's transparent and comprehensive reporting aligns with JORC Code standards, with all significant intercepts disclosed and supporting geological data made available. The company continues to plan infill RC drilling to test extensions of high-grade mineralisation and systematic grade control drilling to refine resource models.
