Rosewood Drilling Hits 33m at 15.7% Heavy Minerals, PTR Targets Q2 Resource

Strongest Drilling Results to Date

PTR Minerals Ltd (ASX, PTR) has announced its best drill assay results yet from the Rosewood Titanium Project in South Australia's northern Gawler Craton. The latest batch of assays, derived from 71 air core drill holes in the Rosewood East area, revealed thick and high-grade heavy mineral (HM) intercepts, including a standout 33-metre interval grading 15.7% HM starting at just 10 metres depth. These results build on previous drilling successes and underscore the project's potential scale and grade.

Project and Drilling Overview

The Rosewood Titanium Project comprises two main areas, Rosewood East, wholly owned by PTR, and Rosewood West, a joint venture with Narryer Metals (ASX, NYM). The recent drilling program completed 446 air core holes totaling 9,388 metres, covering approximately 40 square kilometres. The drilling targeted flat-lying heavy mineral sands, with vertical holes providing reliable thickness and grade data. The mineralisation is characterised by titanium-rich heavy minerals, which are valuable for various industrial applications.

Implications for Resource Estimation

PTR is progressing towards its maiden JORC Mineral Resource Estimate (MRE), scheduled for release in the second quarter of 2026. The consistent high-grade intercepts starting near surface provide strong confidence in the continuity and quality of the mineralised system. The company is conducting extensive metallurgical testing, including mineral assemblage analysis and gravity spiral processing trials, to optimise recovery and product quality. These efforts aim to underpin a robust resource model and support future development plans.

Strategic Position and Next Steps

With titanium demand rising globally, PTR’s Rosewood Project could become a significant new source of high-quality heavy mineral sands. The coarse-grained nature of the deposit suggests favourable processing characteristics, potentially enabling efficient extraction. PTR’s CEO, Peter Reid, highlighted the exceptional nature of the latest results and reaffirmed the company’s commitment to delivering the maiden resource estimate on schedule. Further assay results and metallurgical data are expected in the coming months, which will provide greater clarity on the project’s economic potential.

Broader Exploration Portfolio

Beyond Rosewood, PTR Minerals holds promising copper, gold, and rare earth projects in South Australia’s Olympic Copper-Gold Province and other regions. These include the Woomera and Mabel Creek copper-gold projects and the Comet rare earths project. The company’s diversified portfolio positions it well to capitalise on multiple critical mineral opportunities in the region.
