Evergold Minerals extends its 2026 drilling success at Duchess of York with high-grade gold intercepts and broad mineralisation from surface to over 100m depth, reinforcing its exploration model at Mt Monger.
- High-grade intercepts up to 7.90 g/t Au over 2m
- Broad mineralised zones confirmed from surface to 100m+ depth
- 80% of 2026 RC assays received, more pending
- Upcoming regional aircore drilling to test geological model
- Soil survey completed at Leonora's Craig’s Rest Prospect
Duchess of York Drilling Extends Gold Mineralisation
Evergold Minerals Limited (ASX:EG1) has delivered further evidence of a substantial gold system at its Duchess of York Prospect within the Mt Monger Gold Project. The latest batch of assay results from 15 reverse circulation (RC) drill holes continues to confirm both high-grade and broad zones of gold mineralisation extending from near surface to depths beyond 100 metres.
Standout intercepts include 2 metres at 7.90 grams per tonne (g/t) gold from 43 metres in hole MM26RC0009 and 3 metres at 5.11 g/t, including a 1-metre interval at 11.46 g/t from just 3 metres depth in MM26RC0012. The 7.90 g/t intercept represents the highest grade returned so far in this drilling campaign.
Scale and Continuity Reinforce Geological Model
With assays now received for approximately 80% of the 2026 RC program, the results reinforce Evergold’s interpretation of a structurally controlled gold system associated with a felsic sanukitoid intrusive emplacement adjacent to the Gladiator Fault. This geological setting is the cornerstone of the company's exploration model across the Mt Monger camp.
Broad mineralised zones such as 19 metres at 1.48 g/t from 56 metres (including 5 metres at 2.04 g/t) and 18 metres at 1.23 g/t from 8 metres (including 5 metres at 1.80 g/t) demonstrate the system’s scale and continuity. Notably, hole MM26RC0014 ended in mineralisation at 105 metres, indicating the gold system remains open at depth.
These results build on earlier drilling success reported in June 2026, which revealed wide mineralisation extending below historical drilling, and support ongoing confidence in the prospect’s potential. Drill holes were strategically oriented perpendicular to the dominant north-south structural grain to best capture mineralisation widths, though true widths are yet to be confirmed.
Strategic Location and Project Pipeline
The Mt Monger Project is located about 70 kilometres southeast of Kalgoorlie in Western Australia’s prolific Eastern Goldfields region. Evergold controls a contiguous landholding along a major regional structural corridor known to host significant gold mineralisation. The Duchess of York Prospect is the company’s most advanced target, complemented by other prospects including Hickman’s Find, Red Dale North, Kiaki Soaks, and the newly defined Gladiator Prospect.
Importantly, the project benefits from proximity to existing processing infrastructure, notably Vault Minerals’ 1.2 million tonnes per annum Randalls Gold Mill less than 5 kilometres away, as well as additional facilities at Jubilee, St Ives, and Lakewood within 50 kilometres.
Leonora Soil Survey and Upcoming Exploration
Beyond Mt Monger, Evergold has completed a regional soil geochemical survey at the Craig’s Rest Prospect within its Leonora Goldfields Project. The survey collected 1,320 soil samples aimed at defining gold dispersion associated with priority structural targets. Assay results are expected within the next month or so.
Looking ahead, Evergold plans to commence a regional aircore drilling program at Mt Monger in roughly two weeks. This will test the repeatability of the Duchess of York geological model across the project’s broader pipeline. Phase 2 RC drilling at Duchess of York will focus on down-dip, along-strike, and offset extensions, while diamond drilling at Gladiator is set to proceed under a government co-funded Environmental Impact Statement (EIS) program.
Director Glenn Grayson emphasised the company’s ambition to leverage the Duchess of York discovery template to unlock multiple gold systems across Mt Monger, highlighting the strategic importance of the upcoming regional aircore program.
Bottom Line?
Evergold’s expanding drilling footprint at Duchess of York confirms a significant gold system, setting the stage for regional testing and resource definition in the months ahead.
Questions in the middle?
- Will the remaining assays from the maiden RC program at Gladiator confirm a similar intrusion-related gold system?
- How will phase 2 RC drilling refine the understanding of mineralisation continuity and grade at Duchess of York?
- Can the regional aircore program validate the geological model across other prospective targets at Mt Monger?
