Red Mountain’s Solo: where the earth is heavy, rare and magnificent

Red Mountain is enjoying a magnificent start to 2022 with assays showing heavy rare earths dominate the make-up of mineralisation at the Solo prospect in Mt Mansbridge.

Drilling at the prospect returned a top result of 5m grading 0.316% total rare earth oxide (TREO) with valuable heavy rare earths making up 66.62% of the rare earths content in hole MMRC002.

Red Mountain Mining (ASX:RMX) is pretty excited over the large distribution of yttrium as well – because the dominance of elements such as dysprosium (5.65%) and terbium (0.97%) suggests the intersected mineralisation is xenotime, a major source of rare earths.

Mineralisation is associated with a silica altered structure, hosted within a broader package of quartz and quartz mica greywackes and occasional finer grained pelites.

Assays from the remainder of hole MMRC002 as well as from holes MMRC001 and 003 from the prospect will be returned and reported upon in February 2022.

Didn’t we already do this one: Drilling at Déjà vu

The company also drilled hole MMRC004 at the Déjà vu prospect to a depth of 75m.

Assays returned a consistent interval of 16m grading 112.8 parts per million cobalt with gradually increasing values of magnesium and nickel, which alludes to a zone of increased fertility deeper in the intrusive system.

However, further drilling is required as the hole finished short of the target zone.

Upcoming activity

Red Mountain had completed four of the planned holes at the project before the onset of the wet season within Western Australia’s Kimberley region that made access untenable.

With substantial access tracks now established at Mt Mansbridge and heritage clearance achieved, the company is planning to resume the drill program once the site is accessible again in early 2022.
