Key Highlights

Evergold Minerals began about 8,000 metres of Reverse Circulation Drilling at Duchess of York on 11 November 2026.
The drilling is designed to support a maiden Mineral Resource Estimate targeted for early 2027.
A gold-arsenic anomaly at Vanguard covers roughly 900 metres by 650 metres, and is being tested with follow-up drilling.
Metallurgical test results for Duchess of York are expected later in November, with first production targeted for the second half of 2027.

Evergold Minerals Limited (ASX:EG1) has started resource definition reverse circulation drilling at its Duchess of York prospect within the Mt Monger Gold Project, according to an update dated 12 November 2026. The program is about 8,000 metres in total and has been designed to support a maiden Mineral Resource Estimate targeted for early 2027. Mt Monger sits about 70 kilometres southeast of Kalgoorlie in Western Australia. The update also sets out follow-up drilling at the Vanguard and Kiaki Soaks prospects and a revised development pathway across the company's Mt Monger and Leonora projects.

Duchess of York and the path to a resource

Drilling at Duchess of York commenced on 11 November 2026, using a Red Rock Drilling rig after site preparation by Saltbush Contracting. The resource definition program is intended to test the continuity, geometry and grade distribution of mineralisation at a spacing that could support a maiden estimate. Resource definition drilling at the prospect is expected to be completed by the end of November, which would leave the resource modelling and assay work for the first months of 2027.

The previous maiden RC program, completed in July 2026, returned intercepts including 25 metres at 3.47 g/t gold from 3 metres, including 1 metre at 52.7 g/t from 9 metres. Metallurgical test work covering oxide, transitional and fresh mineralisation began in October 2026. The company says initial results are expected later in November, while the next-steps section of the update refers to results next week, an inconsistency that shareholders may want clarified as the program progresses.

Vanguard and Kiaki Soaks

Vanguard lies about 600 metres northwest of the Duchess of York main zone. Earlier shallow aircore drilling returned 19 metres at 0.86 g/t gold from 28 metres, including 4 metres at 2.37 g/t from 40 metres. The company has also delineated a gold anomaly above 0.1 g/t covering about 450 metres by 300 metres, enclosed by an arsenic anomaly above 50 ppm of roughly 900 by 650 metres. The arsenic anomaly sits largely within a low-density body that the company has interpreted as a concealed intrusion, and the company believes it may reflect a larger mineralised system.

Kiaki Soaks is a prospect where historical drilling returned 40 metres at 2.49 g/t gold from 32 metres. The company has not independently verified those historical results, and the planned drilling will be its first at the prospect. The historical data include older holes that were reported by other operators, and the company itself notes that their continuity and grade remain untested.

Timing, targets and open questions

The company is targeting first gold production from its portfolio in the second half of 2027, with a Mining Lease application for Duchess of York expected in early 2027. The highlights, however, also refer to first production by the end of 2027, a difference in timing that is worth noting. Development studies and mining approvals are planned for the second half of 2027 if the maiden estimate is delivered on schedule.

Several uncertainties remain. The arsenic and gold anomalies at Vanguard are based on single bottom-of-hole samples, the spacing of the data is not sufficient for resource estimation, and the orientation of mineralisation there is not yet known. At Leonora, the Rabbit Warren Acquisition is subject to completion, and the Inferred Mineral Resource at Leonora carries a low level of geological confidence. The company has also cautioned that forward-looking statements may differ materially from eventual results.

Final Word

Evergold has moved its Duchess of York project into a defined drilling phase, with a maiden resource estimate and a development timetable now set out for 2027. The results of the current program, the metallurgical testing and the follow-up drilling at Vanguard and Kiaki Soaks will determine whether the schedule holds. Until those results are available, the timing of a maiden estimate and first production remains dependent on drilling outcomes, assay turnaround and regulatory approvals.
