General Mining to kick off drilling at Uvs potash project in Mongolia

Perth-based General Mining (ASX: GNM) is to commence drilling in September at its fully owned Uvs Basin potash project in Mongolia, once all necessary approvals are received.



The project comprises 5 granted exploration licences covering more than 2,000 km2 within the Uvs Nuur Basin that is considered prospective for bedded and domal (salt diapir) potash deposits as well as for lithium and potassium brines.



Some rock salt, soda ash & gypsum deposits and base metal occurrences have been discovered within the Uvs Basin and limited drilling at the northern periphery of the basin in the 1950-60s intersected shallow potash mineralisation in up to 600 m thick Devonian evaporates.



These drilling results from the Russian part of the Uvs Nuur Basin confirm the prospectivity for solid potash and/or potassium brine deposits.



The company’s exploration team, working together with German consulting firm ERCOSPLAN Ingenieurgesellschaft Geotechnik und Bergbau mbH, carried out field reconnaissance at the Uvs project.



This program was designed to follow up on ERCOSPLAN’s desktop overview study and the Company’s in-house remote sensing research.



The exploration team carried out surface mapping of some remote sensing circular features within the Company’s exploration ground that were interpreted as possible salt diapir structures.



The company has commissioned a drilling contractor to commence structural drilling of a series of drill holes at these circular features to a depth of about 150 m and totaling 1,200 line metres.



If confirmed by this structural drilling, salt diapir structures could become a priority target for subsequent specialised exploratory drilling aiming at the domal type of potash deposits.



The company also plans to use the availability of a drilling rig at the Uvs project to test areas of previously unexplored alluvial placer potential within the company’s exploration licences.
