Summary

Power Minerals Limited has reported new high-grade rare earth oxide (REO) drill results from drillhole MFSR-054 at its Morro do Ferro Project in Brazil, including the deepest high-grade intersection to date of 2m at 6.88% TREO from 240m. The drilling also returned significant wide intercepts from surface, such as 50m at 9.0% TREO, extending mineralization to an impressive depth and providing crucial data for a planned maiden JORC Mineral Resource Estimate. The results confirm the continuation of high-grade REO mineralization and are supported by comprehensive QA/QC protocols.

Reasoning: The announcement reports new, high-grade rare earth oxide (REO) drill results from the Morro do Ferro Project, including the deepest high-grade intersection to date. These results extend known mineralization at depth and from surface, providing critical data for an upcoming maiden Mineral Resource Estimate. The grades are exceptional compared to industry peers, and the program is supported by robust QA/QC and JORC compliance, indicating high materiality and novelty despite the lack of true width disclosure.

Positive factors

Deepest high-grade REE intersection to date (6.88% TREO at 240m) extends mineralization at depth.
Significant wide intercepts of high-grade TREO (e.g., 50m at 9.0% TREO) from surface.
Mineralization confirmed to an impressive depth of 190m and beyond, supporting a maiden JORC MRE.
Detailed QA/QC procedures and JORC compliance enhance data credibility.
Grades are significantly higher than peer comparison averages.

Negative factors

True width not known for reported downhole lengths.
Aggregated intervals reported without explicit cut-off grades.

“The geochemical results for the drillholes were analysed using methods ICP95A and IMS95A. These analyses involved crushing and pulverising to 95% <150#, then lithium metaborate fusion followed by ICP-OES/MS to determine the whole-rock concentration of 48 major oxides and trace elements (including LOI by PHY01E). Samples with concentrations of REO and Th above the method detection limit were re-analysed using the SGS Geosol method IMS95RS. If niobium by method IMS95A is above the upper limit of 0.1% Nb, then the method ICP95A is used for Nb. Due to the doubly charged interferences between gallium and elevated LREE, SGS Geosol does not report Ga analyses by ICP-MS if Ce is over 1000ppm. The lithium borate fusion method ensures a complete breakdown of samples, even those containing the most resilient acid-resistant minerals. This technique is deemed suitable for analysing REO from the Morro do Ferro Project. The table below lists the general elements measured by the SGS methods along with their corresponding detection limits:(17.1) ICP95A Determination by Fusion with Lithium Metaborate - ICP OES Al2O3 0.01 - 75 (%) Ba 10 - 100000 (ppm) CaO 0.01 - 60 (%) Cr2O3 0.01 - 10 (%) Fe2O3 0.01 - 75 (%) K2O 0.01 - 25 (%) MgO 0.01 - 30 (%) MnO 0.01 - 10 (%) Na2O 0.01 - 30 (%) P2O5 0.01 - 25 (%) SiO2 0.01 - 90 (%) Sr 10 - 100000 (ppm) TiO2 0.01 - 25 (%) V 5 - 10000 (ppm) Zn 5 - 10000 (ppm) Zr 11 - 100000 (ppm) Determination by Fusion with Lithium Metaborate - ICP MS Ce 0.1 - 10000 (ppm) Co 0.5 - 10000 (ppm) Cs 0.05 - 1000 (ppm) Cu 5 - 10000 (ppm) Dy 0.05 - 1000 (ppm) Er 0.05 - 1000 (ppm) Eu 0.05 - 1000 (ppm) Ga 0.1 - 10000 (ppm) Gd 0.05 - 1000 (ppm) Hf 0.05 - 500 (ppm) Ho 0.05 - 1000 (ppm) La 0.1 - 10000 (ppm) Lu 0.05 - 1000 (ppm) Mo 2 - 10000 (ppm) Nb 0.05 - 1000 (ppm) Nd 0.1 - 10000 (ppm) Ni 5 - 10000 (ppm) Pr 0.5 - 10000 (ppm) Rb 0.2 - 10000 (ppm) Sm 0.1 - 10000 (ppm) Sn 0.3 - 1000 (ppm) Ta 0.5 - 10000 (ppm) Tb 0.05 - 1000 (ppm) Th 0.1 - 10000 (ppm) Ti 0.05 - 1000 (ppm) Tm 0.5 - 1000 (ppm) U 0.05 - 1000 (ppm) W 0.1 - 10000 (ppm) Y 0.05 - 10000 (ppm) Yb 0.1 - 1000 (ppm) (17.3) PHY01E LOI -45 - 100 (%) Determination of Loss on Ignition (LOI) by Gravimetric Method -1000°C Loss on ignition (LOI) - Loss on ignition by calcination of the sample at 1000°C (17.2) IMS95A The four laboratory batches included six blind blanks (three were CRM), nine blind duplicate samples and nine OREAS certified standards. There are also nine laboratory repeat or duplicate analyses by SGS Geosol. All QC results were well within acceptable limits.”

QP/CP Signedpositive · Story-specific tag

Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.

Why it applies: Steven Cooper, FAusIMM, Global Exploration Manager, is named as the Competent Person responsible for the exploration results.

Evidence · text

“Steven Cooper, FAusIMM (No. 108265), FGS (No. 1030687). Mr Cooper is the Global Exploration Manager and is a full-time employee of the Company. Mr Cooper has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activity being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Cooper consents to the inclusion in the announcement of the matters based on his information in the form and context in which it appears.”

Apparent Width Onlynegative

Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The release explicitly states that reported widths are downhole and may not represent true width.

Evidence · text

“widths are downhole and may not represent true width.”

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: The aggregated intervals are reported as weighted averages with no explicit cut-off grades stated.

Evidence · text

“Weighted averages of all samples across the reported length, with no cut-off unless stated otherwise”

Deleterious Elements Presentnegative

Penalty elements (arsenic, antimony, etc.) or refractory concerns noted in the release.

Why it applies: The release mentions potential issues with gallium interference and discusses thorium and uranium concentrations, noting the project is in a 'Medium Risk Category' for NORM activity.

Evidence · text

“Due to the doubly charged interferences between gallium and elevated LREE, SGS Geosol does not report Ga analyses by ICP-MS if Ce is over 1000ppm. ... The calculated activity value, including all decay products during the mining process, is an average of 94 Bq/g, with a peak of 377 Bq/g (conservative scenario of 2 standard deviations) applied to account for high NORM activity concentrations within the active mining zone. These calculated values by SA Radiation confirm that Morro do Ferro is within the Brazilian NNEC Medium Risk Category II (100 to 500 Bq/g), and not in the high-risk Category I (>500 Bq/g).”

Reasoning: This intercept shows exceptional grade at significant depth, which is highly positive for extending the known mineralization and supporting the maiden MRE.

Positive factors

Exceptional grade (0.60% TREO) for rare earths, well above peer average and project average.
Located at a significant depth (252m), extending mineralization.
Contributes to maiden JORC MRE.

Negative factors

Narrow intercept length (1.6m).
True width not stated.

Tags used in scoring

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: qaqc_disclosed is true

Cut-off Undisclosednegative

High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff_grade was stated

Deleterious Elements Presentnegative

Penalty elements (arsenic, antimony, etc.) or refractory concerns noted in the release.

Why it applies: deleterious_flag is true

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
