South Harz Potash Limited announced the assay results from the recently completed drill hole OHM-02 located within the Ohmgebirge Mining Licence ("Ohmgebirge") area of its South Harz Potash Project. Drill hole OHM-02 was completed to a depth of 721.32m to fully penetrate the known Staßfurt Potash Horizon (z2KSt) and was designed to twin and validate the results of the historic drill hole Kal Wr 6 Liese, which was drilled in 1906. The historic drillhole recorded potash within the Staßfurt Potash Horizon from a depth of 651.70m to 657.20m (5.5m thick) with an historic reported grade of 15.72% K2O.

(ASX announcement 23rd December 2019[1]). The recently drilled confirmatory drill hole, OHM-02, located 148m west of the historic drillhole, intercepted the top of the potash horizon from 651.53m down to a depth of 662.51m, a total apparent thickness of 10.98m and an interpreted true (vertical) thickness of 7.51m. A comprehensive assay suite comprising wet ICP and XRD analyses has identified three distinct mineralized potash horizons comprising a Kieseritic Hartsalz, Anhydritic Hartsalz and Carnallitic Sylvinite Hartsalz, which is a common potash zonation found in the adjacent historical mines of the South Harz Potash district.

Work is progressing well on the company's second drillhole OHM-01, where the objective is to fully penetrate the known potash horizon in the area down to a depth of 813m. The drillhole is designed to twin the historical drillhole, Kal Ktf 5/83, which recorded a potash intercept from 785.2m to 788.2m (3.0 m thick) with an historic reported grade of 12.4% K2O. The target for completion of this drillhole has been extended to the 2nd week of May (previously end-April) due to some early technical issues in the upper limestone horizons which have now been overcome.

The expected timing for the Mineral Resource Estimate update is now early third quarter of 2022. Drilling and assay of core from these two confirmatory drillholes is intended to allow South Harz to upgrade a substantial proportion of the current Ohmgebirge JORC (2012) Inferred Mineral Resource estimate to the Indicated category. Subject to concurrent and satisfactory advancement of all modifying factors, this is expected to allow the release of a comprehensive Scoping Study (a preliminary technical and economic assessment) for Ohmgebirge.
