Spark Highlights Yttrium at Depth in Arapaima's Rare Earth System: 28 m at 200 ppm Y2O3 and 1,614 ppm Y2O3 in a Granite Grab Sample

Spark reports strong yttrium grades at Arapaima but remains early-stage and unfunded.

What the company is saying

Spark Energy Minerals Inc. is emphasizing the presence and distribution of yttrium across its 100%-owned Arapaima Project in Minas Gerais, Brazil, highlighting both previously published drill and road-cut results and newly disclosed yttrium assays from 914 surface samples. The company frames yttrium as a critical, supply-constrained element essential for semiconductors and aerospace, referencing China's dominance and recent export restrictions. Dr. Fernando Tallarico, Chairman and CEO, positions Arapaima as a potential non-Chinese source, citing high yttrium values in both clay and weathered granite zones and stating that moving from discovery to resource and economic study is the next priority, subject to capital. The announcement stresses technical detail, with specific intervals, grades, and sample counts, but does not mention any resource estimate, economic study, or offtake agreement. The tone is confident about geological potential but candid that all next steps depend on securing financing and regulatory approvals. Applications to the EU and U.S. agencies for critical minerals support are pending, with no decisions or funding yet.

What the data suggests

The disclosed data show multiple high-grade yttrium intervals, including 28 m at 200 ppm Y₂O₃ from 62 to 90 m in ARA-RC-003 at Cruzeta, and 201 ppm Y₂O₃ over the final 24 m of the same hole, which ended in mineralization. Twelve composites exceed 100 ppm Y₂O₃ in 10 of 28 Cruzeta holes, with top values of 460 ppm and 455 ppm Y₂O₃. The Cruzeta road cut returned 22 m at 188 ppm Y₂O₃, and a grab sample from the base yielded 1,614 ppm Y₂O₃ and over 2.00% TREO, with yttrium up to 8% of rare earth oxides. Of 843 primary drill samples, 150 (18%) grade 50 ppm or more and 57 grade 100 ppm or more; all 951 primary drill samples detected Y₂O₃. Surface sampling across 1,038 samples found 48 at 100 ppm Y₂O₃ or more, with highs of 507 ppm in soil and 349 ppm in stream sediment. Yttrium correlates strongly with dysprosium (0.96) and terbium (0.91), and its share of TREO is stable (median 3.9%, range 2.8–6.1%). The project is pre-resource, with no economic assessment or resource estimate initiated. All next steps, including further drilling and metallurgical work, are contingent on financing. Global market context is provided: Chinese exports of yttrium compounds fell from about 3,100 tonnes in 2024 to 1,600 tonnes in 2025, with U.S. imports dropping to zero in May–June 2026; yttrium oxide (99.999%) sells for about US$8/kg in China and US$420–1,175/kg outside China in 2026.

Analysis

The announcement provides detailed and credible technical data on yttrium and rare earth assays from the Arapaima Project, including specific intervals, grades, and sample counts. However, the narrative emphasizes the project's potential and market context (e.g., global supply, price trends) without any resource estimate, economic study, or evidence of near-term monetization. Key forward-looking statements—such as plans for further drilling, metallurgical work, and regulatory applications—are all subject to financing and external approvals, with no timeline for completion or funding secured. The company explicitly states that moving from discovery to resource and economic study depends on capital, highlighting capital intensity with no immediate earnings or resource impact. While the technical disclosure is strong for an exploration-stage company, the tone is optimistic relative to the actual stage of progress, as no resource, offtake, or partnership is in place and all next steps are contingent.

Risk flags

• ●The project is at an early exploration stage with no mineral resource estimate or economic study started, meaning there is no basis for assessing potential scale, recoverability, or economic viability. This limits the ability to value the asset or benchmark it against peers.
• ●All planned drilling and metallurgical work are explicitly subject to securing additional financing, introducing significant funding risk. Without new capital, the company cannot advance to resource definition or economic assessment.
• ●Regulatory and funding applications to the European Union and U.S. Trade and Development Agency remain undecided, so there is no external validation or support for the project yet. The absence of approvals or grants delays potential de-risking or acceleration.
• ●The company has no offtake, partnership, or processing agreement in place, and is 100% owner of the project. This means all technical and financial risk is retained, and there is no external party to share costs or validate the project's marketability.
• ●Yttrium market prices are volatile and highly dependent on Chinese policy, with recent export restrictions causing sharp price differentials between China (US$8/kg) and the rest of the world (US$420–1,175/kg). There is no evidence Spark can access these premium markets without significant further development and qualification.

Bottom line

Spark Energy Minerals has demonstrated that its Arapaima Project hosts significant yttrium mineralization, with multiple high-grade intervals and strong geochemical associations with other heavy rare earths. The technical disclosure is detailed and credible, but the project remains at a pre-resource, pre-economic study stage, with all next steps dependent on raising new capital. No resource estimate, economic assessment, offtake, or partnership is in place, and regulatory or funding applications are still pending. The company is positioning itself as a potential non-Chinese source of yttrium amid tightening global supply, but there is no clear path to monetization or near-term value realization. Investors should focus on whether Spark can secure financing to advance drilling and metallurgical work, and whether future updates deliver a compliant resource estimate or attract strategic partners. The key takeaway is that while the geological results are promising, the project is still high risk and early stage, with significant execution and funding hurdles ahead.

Announcement summary

(CSE:SPRK) (FSE:8PC) Spark Energy Minerals Inc. has released a yttrium-focused review of previously published drilling and road-cut results from its 100% owned Arapaima Project in Minas Gerais, Brazil, along with newly disclosed yttrium results for 914 surface samples. The Cruzeta rare earth zone and deeper weathered granite intervals both show significant yttrium values, with highlights including 28 m at 200 ppm Y₂O₃ from 62 to 90 m in drill hole ARA-RC-003, and 201 ppm Y₂O₃ over the final 24 m of the same hole (70 to 94 m), which ended in mineralization. Twelve composites grade 100 ppm Y₂O₃ or more in 10 of the 28 Cruzeta holes, with notable intervals such as 8 m at 226 ppm (ARA-RC-033), 4 m at 209 ppm (ARA-RC-005), 8 m at 198 ppm (ARA-RC-001), and 10 m at 150 ppm (ARA-RC-018). The two highest drill values are 460 ppm Y₂O₃ (ARA-RC-003, 70–72 m) and 455 ppm Y₂O₃ (ARA-RC-033, 42–44 m). The Cruzeta road cut (channel CN-009) returned 22 m at 188 ppm Y₂O₃, with 16 of 22 samples at 100 ppm or more and a maximum of 428 ppm. A grab sample (ARA-CN-008-05) from the base of the road cut returned 1,614 ppm Y₂O₃ and more than 2.00% TREO, with yttrium accounting for up to 8% of rare earth oxides, 333 ppm Dy₂O₃, and 68 ppm Tb₄O₇. Thirty composites at 50 ppm Y₂O₃ or more were found in 24 of 33 reported holes, including all five holes at Boa Vista, where ARA-RC-031 returned 20 m at 80 ppm Y₂O₃ from 28 m. The newly reported 914 surface samples include 507 ppm Y₂O₃ in soil sample ARA-SL-219 at Boa Vista and 349 ppm Y₂O₃ in stream-sediment sample ARA-SS-410 at Cruzeta; across the full 1,038-sample surface dataset, 48 samples returned 100 ppm Y₂O₃ or more. Of the 843 primary drill samples at Cruzeta, 150 (18%) grade 50 ppm or more and 57 grade 100 ppm or more; Y₂O₃ was detected in all 951 primary drill samples. Yttrium correlates closely with dysprosium (correlation coefficient 0.96) and terbium (0.91), and its share of TREO is stable, with a median of 3.9% and a middle range of 2.8% to 6.1%. The 28 m yttrium composite in ARA-RC-003 averages 3,535 ppm TREO, and the 8 m composite in ARA-RC-033 averages 3,014 ppm TREO. The highest previously published surface value outside the road cut is 532 ppm Y₂O₃ in stream sediment ARA-SS-207 at Cruzeta, with 6,417 ppm TREO; stream sediment ARA-SS-271 at Boa Vista returned 208 ppm Y₂O₃ with 10,016 ppm TREO. Chinese exports of yttrium compounds fell from about 3,100 tonnes in 2024 to about 1,600 tonnes in 2025, and shipments to the United States fell to zero in May and June 2026. Yttrium oxide (99.999%) sells for about US$8 per kilogram in China and has traded at US$420 to 1,175 per kilogram outside China in 2026. Arapaima is 100% owned by Spark and is not subject to any offtake or partnership agreement. The company plans to collar a drill hole at the top of the Cruzeta road cut to test the granite below, subject to financing, and will conduct mineralogical and metallurgical test work on the clay and granite mineralization. Applications under the European Union's Critical Raw Materials Act and to the U.S. Trade and Development Agency remain under evaluation, with no decision or funding awarded.
