Hamelin Gold (ASX:HMG) has defined two gold lodes at the Aurora prospect and identified nearby reef-style mineralisation at its Day Dawn Gold Project in Western Australia.
Assays from the company’s maiden reverse circulation (RC) drilling program outline the Upper Aurora Lode, which hosts most of the ‘high-grade’ intersections reported to date, and the sparsely drilled Lower Aurora Lode beneath it.
New Upper Aurora results include 4m @ 4.40 grams per tonne gold (Au) from 47m in hole PDR0018 and 2m @ 12.4g/t Au from 36m in PDR0020.
The Lower Aurora Lode, interpreted to remain open up and down plunge, returned 2m @ 12.4g/t Au from 149m in PDR0028 and 2m @ 4.40g/t Au from 167m in PDR0029.
At the Altus prospect, 50m southeast of Aurora, drilling intersected 1m @ 8.90g/t Au from 29m in PDR0004 and 1m @ 21.50g/t Au from 24m in PDR0005.
Hamelin interprets the Altus results as evidence of a previously unrecognised, flat-lying reef-style mineralised system. The company says it plans to complete a downhole televiewer survey to provide additional structural data for the Aurora and Altus models.
Managing Director Peter Bewick says the latest interpretation broadens the company’s understanding of the Day Dawn system.
“What initially appeared to be a pair of steeply dipping high-grade lodes is now developing into a broader mineralised corridor containing multiple gold-bearing structures,” Bewick says.
Hamelin considers the steeply dipping Aurora lodes to be potential feeder structures and says their geological setting is comparable to the upper portions of Proterozoic sediment-hosted gold systems, including the nearby Telfer Gold-Copper Mine.
The Day Dawn Project covers approximately 20km² and lies 10km northwest of Telfer, which has produced more than 20 million ounces of gold.
The company notes a follow-up 3,000m RC program is scheduled to begin within two to three weeks to test extensions and additional lodes at Aurora and Altus. Drilling is expected to finish in early September, with assays anticipated in October 2026.
An Exploration Incentive Scheme (EIS) co-funded diamond drilling program is planned to begin in the second half of September. It will test the interpreted intersection of the mineralised feeder system and prospective Telfer formation stratigraphy at depth.
Hamelin Gold is an exploration company based in Perth with landholdings in the Tanami, Paterson, and Yilgarn provinces of Western Australia. The company’s shareholders include Gold Fields (NYSE:GFI) and Vault Minerals (ASX:VAU).
