Delving deeper into Pomme carbonatite reveals potential for rare earth-rich magnetic resource ‘of significant scale’ | spcilvly

  • Recent diamond drilling tests have intercepted up to 2.72% TREO, up to 32% NdPr in TREO
  • The results validate the interpretation that the Pomme carbonatite “contains a very large mineralized system”
  • More trials were pending at the time of writing.
  • Pomme has similar geology to neighboring Geomega Resources’ world-class Montviel REE carbonatite deposit.

Diamond drilling results of up to 2.27% TREO from MTM Critical Minerals’ Pomme REE-niobium project in Quebec, Canada confirm that this could be a very large mineralized system hosted in carbonatite with high percentages of magnetic rare earths.

With only around 600 of these occurrences known worldwide, carbonatites are rare deposits of high-quality hard rock that are a major source of REE and niobium.

The carbonatite intrusion in MTM Critical Metals (ASX:MTM) Pomme has similar geology to nearby Geomega Resources’ world-class Montviel deposit, which has a resource of 266Mt @ 1.45% TREO and 0.14% niobium (Nb).

MTM says Pomme increasingly has the potential to contain an “economic resource of some scale”, for magnetic rare earths and niobium, which are highly sought after for use in batteries and advanced technologies.

The company said last month that its The exploration strategy was to discover zones of ~1.5% or more TREO and the latest trials have proven this once again, surpassing the previous highest level of 1.62% TREO.

Second batch of diamond drilling further confirms extensive mineralization

The company has now achieved significant total rare earth oxide (TREO) mineralization of up to 2.72% and 32% neodymium and praseodymium (NdPr) in TREO from its ~5,700m and 13-hole diamond drilling campaign.

These impacts over wide intervals come from previously untested areas of the Pomme carbonatite complex.

Hole POM-23-04 showed 266 m @ 0.22% TREO and 0.06% niobium from 36 m, including 39.5 m @ 0.46% TREO and 0.05% niobium from 79 m, including 4, 25 m @ 0.88% TREO and 0.07% niobium.

Well POM-23-05 crossed 276 m at 0.37% TREO and 0.08% niobium, with a best interval of 3.4 m at 1.99% TREO and 0.02% niobium.

This hole tested the south central part of the carbonatite complex and intersected continuous mineralization from 225 m downhole to the end of the hole at a depth of 501 m.

MTM claims the high-value magnetic rare earth content was “particularly high”, with NdPr values ​​of up to 32% in the TREO grade.

MTM CEO Lachlan Reynolds says the latest two holes further validated the company’s interpretation that the Pomme carbonatite contains a very large mineralized system.

“These new assay results come from previously untested parts of the Pomme carbonatite complex and confirm that abundant niobium and rare earth element mineralization is widespread,” says Reynolds.

“Like previously reported results, these drill holes intersected significant zones of higher-grade rare earth mineralization and contained consistently high percentages of NdPr.

“We are starting to see how the carbonatite geology controls the distribution of mineralization and this will be an integral part of our follow-up to test priority areas.

“Pomme is considered to have geological potential to host a resource of significant scale.”
