Power Minerals (ASX:PNN) has delivered another standout rare earth result from Morro do Ferro in Brazil, with MFSR-054 returning 88m @ 6.33% TREO from surface.
That included:
- 50m @ 9.0% TREO from surface
- 20m @ 12.05% TREO from 18m
- 2.18% MREO of whole rock within that 20m interval
Below the high-grade zone, drilling added another 79m @ 1.11% TREO, creating a continuous mineralised interval of 167m.
High grade up top, mineralisation underneath
That is what makes the latest hole interesting.
The upper 88m carries the headline grades, but the system does not simply stop beneath it.
MFSR-054 continued through another 79m of rare earth mineralisation before the currently assayed section ended, while results from the deeper part of the 253.55m hole are still pending.
Power says the deposit boundary has still not been reached.

Four holes, same broad story
MFSR-054 follows a run of strong results from the maiden program.
Earlier drilling included 137m @ 4.31% TREO in MFSR-052, 108.55m @ 4.15% TREO in MFSR-053 and 116m @ 4.78% TREO in MFSR-051.
The significance now is repetition.
One big hole can get attention, several broad, high-grade holes from different orientations start building a geological case.
Maiden resource starts coming into view
Power has now begun planning for a maiden Mineral Resource Estimate at Morro do Ferro.
The company is targeting a shallow initial resource and says the near-surface geometry could lend itself to a potential open-pit development concept if future studies support mining.
That makes the current drilling about more than discovery.
It is increasingly about defining volume, continuity and geometry.
Gallium keeps tagging along
MFSR-054 also returned 1.5m @ 49.8ppm gallium from 96.15m, adding another critical-mineral angle to the system.
Power is still working with laboratories to refine the analytical method because the unusually high rare earth concentrations are complicating gallium analysis.
What’s next
Two rigs remain active in a planned ~25-hole, ~4,000m diamond program.
More assays are pending, metallurgical test work is planned and the company is continuing work toward the maiden MRE.
The first few holes proved Morro do Ferro had grade, the latest one is starting to show how much system may sit around it.
