# Spark Returns 2.00% TREO in a Grab Sample at the Cruzeta Road Cut; Drilling Planned Below Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/spark-returns-2-00-treo-in-a-grab-sample-at-the-cruzeta-road-cut-drilling-planne--135230ae-999b-495f-9553-83934daca463 Original source: https://orestocks.com/company/SPRK.CN/press-releases/6067093924070771 Publisher: orestocks Original announcement: 2026-10-08T09:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-08T09:47:55.490Z Atlas analysis updated: 2026-10-08T09:47:55.490Z - Company: Spark Energy Minerals Inc. - Ticker: SPRK.CN - Exchange: Unavailable - Region: Minas Gerais, Brazil - Primary commodity: Rare earth - Secondary commodities: Gallium, Scandium, Lithium - Document categories: Drill results, Other - Extracted: 2026-10-08 09:47:56 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Spark Energy Minerals reported a high-grade grab sample from the Cruzeta Road Cut at its Arapaima Project in Brazil, returning 19,991 ppm \(2.00%\) total rare earth oxides \(TREO\), the highest assay reported by the company. This sample, taken from granite, indicates a new target style beyond the previously interpreted clay-hosted mineralization. Additionally, channel sampling yielded 22 m averaging 2,392 ppm TREO and 4 m averaging 1,725 ppm TREO, with magnet rare earth oxides accounting for at least 36.0% of TREO in the grab sample. The company plans follow-up drilling below the road cut to test this new target at depth. Reasoning: Spark Energy Minerals reported an exceptionally high-grade rare earth grab sample \(19,991 ppm TREO\), which is the highest assay to date for the company and indicates a new granite-hosted target style at its Arapaima Project. This significantly expands the exploration potential, although the results are preliminary and from surface samples. - Positive factor: Highest rare earth assay reported by the company \(19,991 ppm TREO\) from a grab sample. - Positive factor: Identification of a new granite-hosted rare earth target style, expanding exploration potential beyond the clay-hosted model. - Positive factor: High magnet rare earth oxide \(MREO\) content \(at least 36.0% of TREO\) in the high-grade grab sample. - Positive factor: Channel samples confirm significant surface mineralization \(22 m at 2,392 ppm TREO and 4 m at 1,725 ppm TREO\). - Positive factor: All five nearby drill holes previously ended in rare earth mineralization, suggesting depth potential. - Negative factor: The high-grade grab sample is selective and not representative of the overall target. - Negative factor: Over-limit analysis for praseodymium is pending, meaning the reported TREO is a minimum value. - Negative factor: Channel sample lengths are not true widths or thicknesses of mineralization. - Negative factor: No new drill results are reported in this announcement. - Negative factor: No mineralogical or leach test work has been reported, and metallurgical recovery has not been demonstrated. - Negative factor: QA/QC for channel and grab samples relied on the laboratory's internal program, with limited external reference material coverage. - Negative factor: No independent verification sampling or check assaying at a second laboratory has been undertaken. Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 4 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The grab sample ARA-CN-008-05 returned 19,991 ppm \(2.00%\) TREO, which is an exceptionally high-grade for rare earth elements and the highest reported by the company. Evidence · text > A grab sample of lightly weathered granite at the base of the road-cut face returned 19,991 ppm \(2.00%\) total rare earth oxides \(TREO\), the highest rare earth assay of any single sample the Company has reported at Arapaima. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The reported channel sample lengths for CN-008 \(4 m\) and CN-009 \(22 m\) are sampling lengths along the face and are explicitly stated as not being true widths or thicknesses of mineralization. Evidence · text > Sample lengths are sampling lengths, vertical in CN-008 and horizontal, along the road-cut face, in CN-009. They are not true widths or thicknesses of mineralization, which are not known. **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release includes a detailed 'Sampling, Analytical Procedures and QA/QC' section, mentioning laboratory certification \(ISO 9001:2015 and ISO 14001:2015\), internal QA/QC programs \(blanks, duplicates, certified reference materials\), and data verification by Qualified Persons. Evidence · text > All samples were submitted to SGS Geosol Laboratórios S.A. in Vespasiano, Minas Gerais, Brazil, a commercial laboratory that is independent of the Company and is ISO 9001:2015 and ISO 14001:2015 certified. **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The discovery of granite-hosted rare earth mineralization represents a new target style at Cruzeta, extending exploration beyond the previously interpreted ionic clay model. Evidence · text > The grab sample is granite, not clay, which opens a second target style at Cruzeta beyond our ionic clay model. ## Extracted facts Stored fact records: 4.
