Hamelin Gold (ASX:HMG) has completed an expanded phase two reverse circulation (RC) drilling program at its Day Dawn Gold Project in Western Australia’s Paterson Province.
The company expanded the program from a planned 3,000m to 4,000m across 35 holes, targeting near-surface extensions to the Aurora and Altus gold lodes and down-plunge extensions of the Aurora lodes.
The program also tested for additional parallel lode positions adjacent to the existing mineralisation corridor.
Hamelin has submitted more than 4,000 samples for analysis, with assay results expected in October 2026. The company has completed RC pre-collars for diamond drilling to test further down plunge where the Aurora lodes remain open.
Managing Director Peter Bewick says geological observations from the program support the view that the Aurora and Altus lodes may represent the upper position of a “potentially significant, depth-extensive mineral system”.
“The completion of a series of RC pre-collars has positioned Hamelin to commence its maiden diamond drilling campaign at Day Dawn, marking another important step in unlocking the broader potential of the project,” Bewick says.
The diamond drilling program will commence within four weeks and comprises diamond tails extending selected RC pre-collars, together with dedicated large-diameter core holes through the upper portions of the Aurora and Altus lodes.
The shallow diamond core holes will provide material for preliminary metallurgical test work and generate structural data to refine geological interpretations.
Preliminary structural interpretation has advanced through downhole televiewer surveys completed in selected RC drill holes, providing insights into the orientation and geometry of both lode and reef-style mineralisation.
The Day Dawn Gold Project covers approximately 20km2 and is located 10km northwest of the Telfer gold-copper mine in the Paterson Province.
Initial drilling has defined the Aurora-Altus system as a series of steeply dipping, parallel gold lodes within a primary mineralisation corridor that remains open down plunge.
Hamelin Gold is an Australian explorer whose flagship West Tanami Project covers roughly 2,500km2 in Western Australia’s Tanami region.
