Parkway Minerals granted US patent for its potassium extraction process
Parkway Minerals NL (ASX:PWN) has been granted a US Patent for its K-Max® potassium extraction process.
The K-Max process was developed to treat potassium rich minerals, including glauconite, to produce sulphate of potash (SOP).
Parkway has a major land holding over one of the world's largest known glauconite deposits, covering over 1,050 square kilometres in the greensand deposits of the Dandaragan Trough.
Large, near surface deposits with existing infrastructure
The Dandaragan Trough in Western Australia's Perth Basin contains substantial deposits of greensands, consisting principally of a mixture of quartz sand and glauconite.
Parkway managing director Patrick McManus said: "Granting of this patent, and others in key countries, confirms the potential of the K-Max® process.
"It is particularly valuable to the Dandaragan Trough, where we have very large, near surface deposits, with existing infrastructure, close to export ports in a region that imports 90% of its phosphate and potash needs."
