Highlights
- Bulk sample from Rosewood East set for metallurgical testing
- Phase-two drilling completed across expanded area
- Stake in EL6715 increased to 70% under JV terms
Petratherm (ASX:PTR) continues to make significant progress at its Muckanippie Project in South Australia, targeting the recovery of heavy minerals through focused exploration and processing efforts. The company recently collected a one-tonne bulk sample from mineralised zones within the Rosewood East discovery area to inform future mineral recovery methods.
This bulk sample is now being prepared for metallurgical testing in Brisbane, where it will undergo processing through a wet concentrator plant, followed by magnetic and electrostatic separation techniques. The objective is to generate initial heavy mineral concentrates that will help define optimal separation methods and shape the final mineral product.
Alongside this, Petratherm has completed its phase-two extension drilling program at the Rosewood Titanium Discovery and other nearby prospects within the broader Muckanippie area. This recent program included 128 drill holes covering 4,486 metres and was designed to test for potential extensions of heavy mineralisation approximately 1.6 kilometres north of the currently defined mineralised boundary.
The company confirmed that further exploration drilling is scheduled to commence later this quarter. This next phase will be supported by a heritage survey previously conducted, enabling Petratherm to expand drilling efforts several kilometres further in multiple directions – north, east, and west – from current operations.
In addition to the technical progress, Petratherm has advanced its strategic position within the Muckanippie Project by earning a majority stake in Exploration Licence EL6715. Under the terms of a farm-in and joint venture agreement with Narryer Metals (ASX:NYM), Petratherm has completed the stage-one commitment and secured a 51% interest in the tenement. The company has opted to increase its stake to 70% by committing an additional $300,000 in expenditure over the next two years.
These developments align with Petratherm’s broader focus as a copper and critical minerals explorer, aiming to uncover new opportunities in both frontier and established mineral regions across Australia. The combination of ongoing exploration, targeted metallurgical testing, and strategic project ownership continues to shape the company’s growth trajectory within the critical minerals sector.
