Turnstone Resources Ltd. has launched a review of its German potash portfolio as it accelerates its expansion into critical minerals across Europe.
The board is evaluating options to unlock value from the legacy fertiliser assets, including the flagship Ohmgebirge project.
Potential pathways under consideration include demerging the potash business into a separate listed or unlisted corporate entity, executing a trade sale, or introducing a joint venture partner directly into the holding subsidiary.
The review follows Turnstone’s pivot toward the critical minerals sector. Initiated in mid-2025, the transition led to the company’s rebrand from South Harz Potash Ltd in March.
Central to its new focus is the acquisition of a prospective copper-gold portfolio in Sweden’s Värmland district. Turnstone recently exercised its option to acquire the Glava 100 exploration licence from McKnight Resources AB and secured six additional surrounding licences.
Collectively covering 100 square kilometres, the Swedish tenure transfer remains subject to regulatory clearance from the Mining Inspectorate of Sweden and shareholder approval, scheduled for a vote on September 14. Turnstone expects to receive final regulatory approvals early in the December quarter.
Moving forward, the company intends to evaluate further asset additions against strict criteria, targeting critical minerals driven by the clean energy transition, defence, and electronics in Tier-1 jurisdictions with stable legislative backing.
Turnstone Resources CEO Len Jubber said: “The acquisition of the Swedish copper-gold portfolio and our exploration to date has anchored our Critical Minerals Strategy and created the exciting opportunity to pursue a complementary asset.
“The initiation of the strategic review to consider additional critical minerals opportunities and the options to unlock the value of our German potash assets is an important next step in positioning Turnstone to maximise shareholder value.”
Turnstone confirmed no decision has been made regarding the structure or timing of any potential potash transaction.
The company acknowledged its long-term shareholder base that supported the initial development of Ohmgebirge, noting that any corporate action will aim to preserve upside exposure for existing investors.
