Turnstone Resources Ltd (ASX:TSR) Share Price & Analysis

Turnstone Resources Ltd (ASX: TSR), formerly known as South Harz Potash Ltd, is an Australian mineral exploration and development company headquartered in West Perth, Western Australia. The company is primarily focused on the discovery and advancement of essential mineral resources required for global food security and the green energy transition. Following a strategic rebranding in early 2026, the entity transitioned to its current name and ticker symbol to reflect a broader focus on European critical minerals.

The company's flagship asset is the South Harz Potash Project located in the Thuringia region of Germany, which represents one of the world's largest undeveloped potash basins. In addition to its potash interests, Turnstone Resources has expanded its operational footprint into Sweden, where it is actively exploring for copper and gold at the Glava-Klinten and Torsby West projects. These diversified assets provide the company with exposure to both the agricultural fertilizer market and the growing demand for metals essential to electrification.

Turnstone Resources employs a strategic growth model centered on leveraging its established presence in Tier 1 European mining jurisdictions to supply local markets. By positioning itself as a regional supplier of potash and critical minerals, the company aims to reduce supply chain risks for European industrial and agricultural consumers. Its value proposition is built on the combination of large-scale brownfield potash resources and high-potential greenfield exploration targets within stable, well-regulated mining environments.
