Davenport Resources Ltd. defined a potash exploration target for its Ohmgebirge project, part of its South Harz property in Germany.
The company said June 18 that it used a historical resource estimate to define the exploration target, which is 183 million to 271 million tonnes of ore grading between 10.82% and 17.0% potassium oxide, or K2O, for 20 million to 46 million tonnes of K2O.
The historical resource estimate comprises 149.1 million tonnes grading an average 13.5% K2O, representing 20.1 million tonnes of K2O. The analysis covers three areas and incorporates data from 13 drillholes completed as of 1984.
"These areas were scheduled for production as extensions of the nearby GDR state potash mines, which were closed after German reunification in the early 1990s," Managing Director Chris Gilchrist said in a statement.
Davenport also said mineralization primarily comprises sylvinite, with an additional lower-classification historical resource of 9.42 million tonnes of K2O associated with carnallitite mineralization. Sylvinite is a mixture of sylvite and halite, while carnallitite is a mixture of carnallite and halite.
The company is prioritizing areas of its property in Germany ahead of further evaluation and potential drill testing.
