Mineral exploration company, Mount Ridley Mines has upped the ante in its rare earth element hunt at its Mount Ridley project near Esperance in Western Australia where re-assayed historical drill data is now defining a relatively shallow mineralised zone that stretches across more than 25 kilometres of strike. Curiously, the results have shown continuity of mineralisation between Winston’s and the Lake prospect which now combine for a serious mineralised area covering more than 10km in length and 1km in width.
The 100 per cent owned Mount Ridley tenure takes in a vast 3,400 square kilometres across eight granted exploration licences and another licence currently under application.
Rare earths mineralisation at the project occurs as horizontal, sheet-like lenses to a maximum depth of 89m, interpreted by the company to be hosted in a saprolite clay horizon with other lower grade zones occurring within transported cover. Mt Ridley has now launched a geological and litho-geochemical study to better understand the relationship between the rare earths mineralisation and its host structures.
The company is also considering core drilling to verify mineralisation from historical air-core holes and to acquire core for metallurgical and geotechnical testing. Management believes the rare earths grades encountered at Mount Ridley to date are comparable to the Makuutu resource in Uganda, operated by ASX-listed Ionic Rare Earths.
