South Harz Potash (ASX:SHP) announces that the Thuringian mining authority, Thüringer Landesamt für Umwelt, Bergbau und Naturschutz (TLUBN), has granted a 3-year extension to the Gräfentonna exploration licence (to January 2026) following submission of an application in November 2022.
The Gräfentonna exploration licence lies immediately south of the Company’s Ebeleben mining licence and would form the natural extension of any future mine at Ebeleben.
The large licence covers over 216 km-square of known potash territory. It was previously drilled during various campaigns of exploration targeting hydrocarbons up until 1985 with a significant number of these drillholes intercepting potash.

Results from these historical drilling campaigns facilitated South Harz’s estimation of an Exploration Target on the Gräfentonna licence of between 2.678 and 3.396 billion metric tonnes at a potash grade between 4.3% and 25% K2O.
The company reports the potential quantity and grade of the Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.
The Gräfentonna exploration licence has been held by the company’s wholly-owned German subsidiary, Südharz Kali GmbH, since January 2015. The Gräfentonna licence covers the eastern portion of the known potash basin in the South Harz region.
“We are delighted to again announce a multi-year licence extension”
South Harz Managing Director Luis da Silva says: “We are delighted to again announce a multi-year licence extension, this time for the Gräfentonna permit. As with the Küllstedt licence extension last month, our team in Germany has readily demonstrated its strong working relationship with the TLUBN. Our gratitude again goes to the TLUBN for their efficacy in evaluating and approving the licence extension.”
South Harz is a potash exploration and development company with its flagship project located in the South Harz Potash District region of Germany, midway between Frankfurt and Berlin.
