Miramar has completed initial aircore drilling aimed at following up on elevated rare earth elements intercepts noted in historical drilling at its Lang Well project.

Historical drilling in 2010 at the Toben Bore target returned elevated lanthanum and cerium results in several holes and a 4m intersection grading 1,500 parts per million total rare earth oxides from a down-hole depth of 28m in the only sample assayed for REEs.

No other REE analysis or follow-up was carried out at this time until Miramar Resources (ASX:M2R) secured the project in Western Australia’s Murchison region back in 2020.

The company also completed a second line of aircore holes along a north-south fence line over a coherent lanthanum-cerium anomaly in reconnaissance soil samples it collected in 2020. This is coincident with a historical samarium and gold auger anomaly.

Executive chairman Allan Kelly said there was potential for a significant amount of shallow REE mineralisation to be outlined at Lang Well as there are several large samarium auger anomalies that have yet to be analysed for any other rare earths or followed up with any systematic drilling or analysis.

Further aircore drilling is planned pending the results of the just completed program and the grant of the neighbouring exploration licence application.

From gold to rare earths

Lang Well covers a large, complexly folded greenstone belt located between the Deflector and Golden Grove operations.

Auger drilling by Jervois Mining in 2010 identified several large +5km long gold and pathfinder anomalies that have not been followed up with deeper drilling.

More recently, Miramar decided to explore for rare earths after noting the large extent of the auger REE anomalism and strongly elevated lanthanum and cerium results.
