Petratherm Limited (ASX:PTR) Reports Positive Heavy Mineral Sizing Results for Rosewood Project
Heavy Mineral Sizing Analysis
Petratherm Limited (ASX: PTR) announced that 90% of the heavy mineral concentrate from the Rosewood Project exceeds 75 microns in size, with a median grain size of 279 microns. These results confirm the coarse-grained nature of the heavy minerals, making them highly amenable to excellent mineral recoveries using conventional gravity spiral processing techniques.
Future Exploration Plans
The company will commence Phase 2 exploration drilling in mid-March 2025 to extend heavy mineral mineralisation, conduct infill drilling, and obtain bulk samples for metallurgical studies. Further benchtop and small-scale heavy mineral studies, including mineral separation and processing optimisation, are also underway.
Executive Comments
CEO Peter Reid stated, “We are extremely pleased to deliver another fantastic step forward in advancing Rosewood at the Muckanippie Project. The heavy mineral particle sizing confirms that the heavy mineral concentrate is coarse grained and likely to be highly amenable to traditional processing techniques using wet spiral concentrators.
“It’s amazing to think that barely six months ago we were undertaking our first mapping project on Muckanippie and now we have advanced to the point of having demonstrated high-grade HM mineralisation over a continuous 15km² area which remains open for expansion. Concurrently we have demonstrated excellent results from first pass mineralogy and particle sizing with further testwork underway.
“We will be drilling again this month and will be rapidly pushing forward on all aspects of exploration and mineral and metallurgical analysis to continue advancing the project quickly.”
