Evergold Nails Highest-Grade Gold at Duchess of York, Prepares Major Aircore Program

Record Gold Grade Caps Maiden RC Program

Evergold Minerals (ASX:EG1) has delivered a standout performance from its first reverse circulation (RC) drilling campaign at the Duchess of York Prospect within the Mt Monger Gold Project, Western Australia. The final assay batch includes a staggering 1 metre intercept grading 52.74 g/t gold from just 9 metres depth, marking the highest-grade metre ever recorded at Duchess of York.

This intercept is part of a broader 25-metre zone averaging 3.47 g/t gold from 3 metres, illustrating the presence of both high-grade shoots and broad mineralised zones. Other notable results include 6 metres at 5.43 g/t gold from 29 metres and 2 metres at 4.46 g/t gold from 45 metres, confirming the system’s potential to host significant gold mineralisation.

Mineralisation Open and Structurally Complex

The gold mineralisation is structurally controlled, associated with sulphide-bearing quartz veins containing pyrite, arsenopyrite, galena, and sphalerite. The style mirrors the high-grade systems historically mined in the Mt Monger district, with mineralisation occurring in folded vein networks around fold hinges rather than confined to single structures.

Evergold’s drilling has extended known mineralisation down-dip and along strike into previously untested ground, with the system remaining open at depth. The company also notes evidence of supergene enrichment near surface, which may partly explain some of the very high grades close to the top of the system, a feature common in the Eastern Goldfields and potentially beneficial for future development scenarios.

Gladiator Prospect Confirms Gold at Depth

Beyond Duchess of York, maiden RC drilling at the Gladiator Prospect has confirmed gold mineralisation at depth, with an 8-metre intercept at 0.44 g/t gold from 43 metres and a further 1 metre at 0.80 g/t gold from 60 metres. Gladiator shares the same intrusion-related structural setting as Duchess of York, strengthening its status as a priority target within the Mt Monger portfolio.

Scaling Up with a 10,000m+ Aircore Program

Building on these encouraging results, Evergold is preparing to launch a large-scale regional aircore drilling program exceeding 10,000 metres. Scheduled to start next week at Duchess of York, this campaign will systematically test extensions, offsets, and new targets across Mt Monger, including Gladiator, Samurai, Hickman’s Find, and newly defined Crusader and Paladin prospects.

The aircore program aims to apply the intrusion-related structural model proven at Duchess of York to identify additional gold systems along the major regional structural corridor. Follow-up RC drilling will target the best aircore results to further delineate mineralisation at a spacing suitable for a maiden Mineral Resource estimate.

Strategic Location Near Processing Infrastructure

Mt Monger’s proximity to existing infrastructure is a strategic advantage. The project sits less than 5 kilometres from Vault Minerals’ Randalls Gold Mill, a 1.2 Mtpa facility, with other processing plants at Jubilee, St Ives, and Lakewood within 50 kilometres. This accessibility could streamline any future development pathway.

Evergold’s director Glenn Grayson emphasised the immediate shift to expanding the drilling footprint, highlighting the shallow nature of mineralisation that suits aircore drilling and the open potential of the broader mineralised system. The company is also preparing for co-funded diamond drilling at Gladiator and ongoing geophysical and geochemical surveys to refine targets.

While the true widths of mineralisation remain unconfirmed and some near-surface grades may reflect supergene processes, the maiden RC program provides a robust foundation for resource definition and exploration expansion at Mt Monger.
