en.Wedoany.com Reported - Australian-listed exploration company PTR Minerals Limited (ASX: PTR) announced on June 23, 2026, its first Mineral Resource Estimate for the Rosewood Titanium Project, located in the northern Gawler Craton of South Australia. This resource positions it among the world's highest-grade heavy mineral sand deposits.

Reported in accordance with the JORC Code (2012 Edition), the Rosewood Project has a total resource of 463 million tonnes, with an average heavy minerals (HM) grade of 8.8%, containing 40.6 million tonnes of heavy minerals at a cut-off grade of 3% HM. At a higher cut-off grade (8% HM), the resource still stands at 208 million tonnes with a grade of 13.5% HM, highlighting a high-grade core within the deposit.

The Rosewood East deposit within the project is considered a key area for initial development. This zone has a resource of 294 million tonnes at a grade of 9.7% HM, containing 28.5 million tonnes of heavy minerals. Over 95% of this resource is classified as Indicated under the JORC Code. Using a 5.5% HM cut-off grade consistent with metallurgical testing, the Rosewood East deposit has a resource of 208 million tonnes at a grade of 12.1% HM.

Company CEO Peter Reid stated that the resource confirms Rosewood as a globally significant titanium discovery. Its near-surface, continuous, and high-grade mineralisation provides a foundation for potentially long-life, high-efficiency mining operations.

Metallurgical testing shows the ore is amenable to conventional processing, with screening, scrubbing, desliming, and spiral gravity separation recovering 91.3% of heavy minerals from a bulk sample, yielding a concentrate grading 90.8% HM. Valuable heavy minerals account for 93% of total heavy minerals, with high-quality leucoxene comprising 75%.

Located approximately 650 kilometres northwest of Adelaide, the project benefits from transport advantages. The company has commissioned Australian Mining Consultants to conduct open-pit optimisation and mine scheduling studies.

This resource announcement marks a significant milestone for PTR Minerals, achieved in less than 18 months since the project's discovery in early 2025. The company believes significant exploration potential remains within the area and the broader Muckanippie project zone.
