Medaro Mining Sharpens Bastnäs Picture as Drone Data and Drill Targeting Take Shape

Medaro Mining detailed rare earth grades up to 32.99% TREO at Sweden's Bastnäs project, with Phase 2 work planned for 2027.

Medaro Mining used a fresh geological briefing this Tuesday to add context to rare earth findings at its Bastnäs project in central Sweden — a move that sent the explorer's thinly traded shares sharply higher even though the underlying assay numbers were already a month old.

The Canadian-listed company, which trades on the Canadian exchange under the ticker MEDA, confirmed that nine of the 218 rock samples collected during its surface program returned grades above 10% total rare earth oxides (TREO). The standout was sample BS39b, taken from historical waste material at the Cerite Shaft, which graded 32.99% TREO. That sample also carried 4.93% neodymium oxide (Nd?O?) and 1.56% praseodymium oxide (Pr?O??).

Eight further samples from the Old Bastnäs and Stålklockan areas landed between 11.68% and 19.53% TREO. Within the high-grade group, combined neodymium and praseodymium (NdPr) accounted for 19% to 24.9% of total TREO, while light rare earth elements (LREE) made up more than 99% of the distribution.

No New Assays, but a Clearer Read on the Rocks

Management was explicit that the release contains no fresh laboratory results, describing it instead as a deepening of the structural understanding of the property. For an early-stage explorer, that kind of interpretation work is a routine but important step: it helps sharpen where future exploration programs should be aimed.

To pin down which host minerals actually carry the elements, Medaro is now commissioning follow-up mineralogical tests. Chief among the open questions is whether bastnäsite — the mineral that gives the project its name — is genuinely present in the samples, something that has yet to be conclusively confirmed.

Magnetic Survey Sets Up Phase 2

The geological review builds on earlier technical work at the Swedish site. On October 8, Medaro released results from a drone-borne magnetic survey over Bastnäs, in which the exploration team identified several distinct magnetic target zones pointing to possible mineralized structures below surface.

Those measurements form the backbone of the next operational steps. A Phase 2 work program is slated for 2027, by which time the magnetic anomalies and geological datasets are expected to be merged to narrow down targets for potential future drilling. The company also plans to combine the geochemical findings with the drone magnetics and historical mine records to select viable drill sites.

Insider Buying and a €2.45 Million Valuation

Alongside the project updates, media reports flagged a purchase by a company executive. Mark Carruthers, a senior officer at Medaro Mining, acquired a block of 10,000 shares.

Following the latest share price move, Medaro's market capitalization stands at EUR 2.45 million. The stock climbed 29% to EUR 0.2020 in today's trading, extending a run that has kept the explorer firmly in the high-risk microcap corner of the resources sector.

Exploration Data Come With Caveats

Medaro is careful to stress the exploratory nature of the data gathered so far. Selective rock and waste-pile samples do not demonstrate spatial continuity, thickness, or an economically recoverable mineralisation. Until a first drill campaign is completed, the true extent of the Swedish deposit remains an open question — leaving the stock's direction tied to how the next phases of work unfold.
