Brightstar Resources Pursues Aurumin Acquisition to Consolidate Sandstone Assets
Brightstar Resources is set to acquire Aurumin, creating a 2.4 million ounce resource from their combined assets.

Brightstar Resources (ASX:BTR) has entered into a scheme implementation deed with Aurumin (ASX:AUN) under which Brighstar will acquire 100 percent of Aurumin’s issued capital.
The companies agreed on arrangement terms in June, underlining how the transaction will consolidate their tenement holdings in the Central Sandstone region in Western Australia.
Brightstar owns the Sandstone gold project, while Aurumin owns the Central Sandstone gold project.
According to Brightstar, the combined assets would lead to a pro-forma total mineral resource estimate of approximately 2.4 million ounces at 1.5 grams per tonne (g/t) gold.
“We believe that combining Aurumin and Brightstar represents a unique opportunity to build a Western Australian gold business of genuine scale with demonstrable upside that also de-risks future development activities and operations at Sandstone,” commented Brightstar Managing Director Alex Rovira in a Monday (July 21) release.
The transaction amounts to approximately AU$0.12 per Aurumin share, with Aurumin shareholders set to receive one Brightstar share for every four shares held on the scheme’s date. Existing Brightstar shareholders will hold 82 percent of the combined group, while Aurumin shareholders will have the remaining 18 percent.
“(This merger) will underpin the mining future of the Sandstone region. Given our adjacent mineral resources, this transaction makes good commercial sense for us and it’s fantastic that we have now been able to agree terms to make this consolidation a reality,” said Aurumin Managing Director Daniel Raihani.
In December 2024, Brighstar reported drilling results from its expanded portfolio at Sandstone and Jasper Hills, including 21 metres at 2.86 g/t gold, including 1 metre at 26.4 g/t from 146 metres.
For Central Sandstone, Aurumin said its resource is currently 19 million tonnes at 1.5 g/t for 885,000 ounces gold. The project also contains iron, with assays returning grades of up to 67 percent iron.
Subject to court approval and other customary conditions, the transaction is expected to be implemented in October.
Shares of Brightstar rose 1.03 percent a day after the announcement, closing at AU$0.49 on Tuesday (July 22).
