RNS Number : 7563L
South Harz Potash Ltd
17 May 2022


17 May 2022



· Completion of twin hole confirmation drilling program on the Ohmgebirge Mining Licence

· Second drillhole (OHM-1) successfully achieved target final depth below 800m

· Identified potash intersection from OHM-01 has comparable starting depth and thickness to twinned historical drillhole

· Assays pending with expected receipt by early June.



South Harz Potash Limited (ASX:SHP) (South Harz or the Company) is pleased to announce the completion of the twin hole confirmatory drilling program on the Ohmgebirge Mining Licence (Ohmgebirge) area of its 100%-owned South Harz Potash Project in central Germany. The second drillhole in the confirmation program (OHM-01) was safely and successfully completed on Monday 16 May 2022.


Drillhole OHM-01 was designed to twin and validate the results of the historic drillhole, Kal Ktf 5/83, which intercepted the known Staßfurt Potash Horizon (z2KSt) from 784.0m to 802.4m depth (18.4m apparent thickness) and returned a potash interceptfrom 785.2m to 788.2m (3.0m apparent thickness) with a historic reported grade of 12.4% K2O (see SHP ASX release dated 23 December 2019[1]).


Confirmatory drillhole OHM-01 was drilled approximately 100m to the north of the historic drillhole to a target depth of 807.9m. It intercepted the z2KSt from 775.1m to 795.2m depth (20.1m apparent thickness), with the sylvite-rich potash horizon being visually identified from 775.1m to 778.8m (3.7m apparent thickness).


Recovered core has now been logged, photographed, cut and sampled. A total of 84 samples have been delivered to the nearby accredited laboratory of K-Utec Salt Technologies (K-Utec) for a comprehensive assay suite comprising wet ICP and XRD analyses in accordance with DIN EN ISO/EC 17025.

Comprehensive results from the two confirmatory drillholes (for OHM-02 assay results, SHP ASX announcement dated 29 April 2022) are targeted to allow South Harz to upgrade a substantial proportion of the current Ohmgebirge JORC (2012) Inferred Mineral Resource estimate to the Indicated category. This updated Mineral Resource estimate for Ohmgebirge is expected to be completed during late June 2022.


Subject to concurrent and satisfactory advancement of all modifying factors, the upgraded Mineral Resource estimate is expected to allow the announcement of a comprehensive Scoping Study (a preliminary technical and economic assessment) for Ohmgebirge.  This is scheduled for completion during July 2022.




South Harz Managing Director, Dr Chris Gilchrist, commented:

"This marks a major milestone for South Harz, with completion of the second confirmatory drillhole, OHM-01, and its initial positive outcomes, further substantiating our confidence in the accuracy of the 41 historical drillholes in the Ohmgebirge licence area, and indeed the 300 historical drillholes which we acquired as part of our broader suite of South Harz Project mining licences. We now eagerly look forward to the assay results from OHM-01, finalisation of a Mineral Resource estimate update and completion and release of the milestone Ohmgebirge Scoping Study."


On behalf of South Harz Potash Limited,

Dr Chris Gilchrist, Managing Director
