Evergold Minerals Limited (ASX: EG1) reported that aircore drilling at the Duchess of York Prospect within its Mt Monger Gold Project in Western Australia has defined a new shallow gold-mineralised zone about 600 metres northwest of the main Duchess of York zone, named Vanguard. The program completed 132 aircore holes for 2,480 metres between 21 July and 4 August 2026, and key Vanguard intercepts included 19 metres at 0.86 g/t Au from 28 metres including 4 metres at 2.37 g/t Au from 40 metres in MM26AC0022, 9 metres at 1.01 g/t Au from 24 metres in MM26AC0023, and 4 metres at 0.65 g/t Au from 16 metres in MM26AC0024, with additional support from MM26AC0003 returning 8 metres at 0.58 g/t Au from surface. Evergold interprets these shallow aircore results as the near-surface western extension of historical 2021 RC mineralisation, together defining an interpreted footprint of about 250 metres west to east and a further 250 metres north-northeast that remains open, with mineralisation associated with stockwork quartz veining on a porphyry-sediment contact and visible sulphides, similar to the main Duchess of York system. The company said the results are based on 4 metre composite samples and that follow-up RC drilling with 1 metre sampling is scheduled to begin in October 2026 to define grade distribution, continuity, geometry and extent at both Duchess of York and Vanguard, supporting a maiden Mineral Resource Estimate targeted for early 2027, subject to drilling success.
Key Points
Aircore drilling identified a new shallow gold-mineralised zone northwest of Duchess of York named Vanguard.
Vanguard is located about 600 metres northwest of the Duchess of York main zone at the Mt Monger Gold Project in Western Australia.
Best new aircore intercept was 19 metres at 0.86 g/t Au from 28 metres including 4 metres at 2.37 g/t Au from 40 metres in hole MM26AC0022.
Adjacent holes returned 9 metres at 1.01 g/t Au from 24 metres in MM26AC0023 and 4 metres at 0.65 g/t Au from 16 metres in MM26AC0024.
MM26AC0003 returned 8 metres at 0.58 g/t Au from surface, extending the interpreted anomaly to the north-northeast.
Evergold interprets Vanguard as a near-surface western extension of historical 2021 RC gold mineralisation.
Combined 2026 aircore and historical 2021 RC drilling define an interpreted mineralised footprint of about 250 metres west to east.
The Vanguard anomaly extends about 250 metres north-northeast and remains open to the south-west and at depth.
Mineralisation is associated with stockwork quartz veining at a porphyry-sediment contact with visible sulphides, similar to the main Duchess of York zone.
Results were based on 4 metre composite samples and require RC drilling to better define grade distribution and true widths.
A resource definition RC drilling program covering Duchess of York and Vanguard is scheduled to start in October 2026.
Evergold is targeting a maiden Mineral Resource Estimate for Duchess of York in early 2027, subject to drilling results.
