Spark Defines a 21 km2 Rare Earth Target at Boa Vista, Nearly Three Times the Cruzeta Footprint and Anchored by Drilling

(CSE:SPRK, FSE:8PC) Spark Energy Minerals Inc. reports the complete stream-sediment and rock-chip dataset for the Boa Vista area within its 100% owned Arapaima Project in Minas Gerais, Brazil. The company has defined a 21.3 km² target area, 13 km long, based on catchment analysis of anomalous drainages, with all five maiden RC holes located inside this target. These five RC holes returned gallium from surface and intersected the rare earth zone, with composite grades ranging from 1,188 to 1,565 ppm TREO. Hole ARA-RC-032, at the south-eastern edge, returned 34 m at 776 ppm TREO from 4 m, including 2 m at 1,054 ppm, and 12 m at 60.0 g/t Ga₂O₃ from surface. The best samples at Arapaima are within the target, including a 1.0% TREO stream sediment, a 1.54% TREO soil, and a new 4,356 ppm TREO stream sediment (ARA-SS-394, 22.1% MREO/TREO), all within 2 to 6.5 km of the maiden holes. The Boa Vista target is nearly three times the size of the Cruzeta footprint, which covers 7.8 km² with 36 mineralized holes. Of the 37 new samples reported, 25 are anomalous and eight exceed 1,000 ppm TREO; overall, 33 of 53 stream sediments exceed 500 ppm TREO. The next drilling campaign will include about 35 first-pass RC holes on 400 m centres, starting beside the maiden holes in Boa Vista South and then moving to Boa Vista North, for a total of about 1,750 m. The Boa Vista South area (13.5 km²) wraps around the plateau drilled by the maiden holes and includes several high-grade samples, such as ARA-SS-271 (10,036 ppm TREO, 22.4% MREO/TREO, 2,178 ppm NdPr) and ARA-SS-270 (2,106 ppm). The magnet share of the eleven samples in Boa Vista South is 20.1% MREO/TREO. Rock chip ARA-CR-191 in Boa Vista North returned 1,644 ppm TREO with 26.4% MREO/TREO and 68 ppm Y₂O₃, while ARA-CR-195, a grab sample of Caladão Granite, returned 967 ppm TREO with 24.9% MREO/TREO and 86 ppm Y₂O₃. The rare earth results of 81 soils collected along access routes include 40 samples exceeding 500 ppm TREO, led by ARA-SL-219 at 1.54% TREO with 35.3% MREO/TREO. The catchment analysis grouped 28 of 31 anomalous catchments into two main groups: Boa Vista South (13.5 km², 11 catchments, 4 new) and Boa Vista North (7.8 km², 17 catchments, all new), together forming the 21.3 km² Boa Vista target. The company holds 100% beneficial interest in five mineral rights processes with no royalty. The target area is defined for further exploration, with no quantity or grade implied under NI 43-101. The company notes that China mines about 60% of rare earths and refines more than 80% of magnet rare earths, and since April 2025, export licences are required for medium and heavy rare earths. Spark Energy Minerals positions itself as an option for rare earth and gallium supply from outside China, in Brazil, with infrastructure advantages including power, a federal highway, and a railhead to port. The next drilling will focus on the south-western part of the target, where the best stream sediment and soil samples are located two kilometres from the maiden holes, followed by drilling in the north-eastern part with the strongest new sample.

Spark Reports 1.54% TREO in Boa Vista Soil and 137.1 g/t Gallium Oxide in Encachoeirado Rock Sample

(CSE:SPRK, FSE:8PC) Spark Energy Minerals Inc. announced surface sampling results from the Boa Vista and Encachoeirado targets within its Arapaima Project in Minas Gerais, Brazil. At Boa Vista, soil sample ARA-SL-219, collected on strongly kaolinized Caladão Granite saprolite, returned 15,434 ppm (1.54%) TREO with 35.3% MREO/TREO and 5,171 ppm NdPr. Another sample, ARA-SL-080, a pink clayey soil, returned 3,047 ppm TREO with 29.3% MREO/TREO. Forty of the 81 Boa Vista soil samples exceeded 500 ppm TREO. Gallium results for these samples included 59 above 50 g/t Ga₂O₃, with a maximum of 134.4 g/t. Five maiden RC holes at Boa Vista intersected the rare earth zone from 20 to 32 m below surface, with composites of 1,188 to 1,565 ppm TREO and 17.3% to 23.4% MREO/TREO. At the Cruzeta road cut, channel sampling averaged 2,392 ppm TREO over 22 m, and a grab sample returned at least 2.00% TREO. At Encachoeirado, six of 65 stream-sediment samples exceeded 500 ppm TREO, with a maximum of 1,621 ppm (ARA-SS-292a) and 19.7% MREO/TREO. A pegmatite-biotitite rock chip (ARA-CR-184) returned 2,428 ppm TREO, 20.3% MREO/TREO, 637 ppm Li₂O, and 137.1 g/t Ga₂O₃. Four of 29 rock-chip series samples exceeded 500 ppm TREO, including ARA-CR-168 (1,212 ppm), ARA-CR-165 (657 ppm), and ARA-CR-186 (520 ppm). Five of 13 soils at Encachoeirado exceeded 50 g/t Ga₂O₃, with a maximum of 65.9 g/t (ARA-SL-121). None of the 13 soil samples at Encachoeirado exceeded 500 ppm TREO (maximum 481 ppm). The company plans close-spaced soil sampling and RC drilling at Boa Vista where the rare earth zone is exposed, and trenching and channel sampling at Encachoeirado, subject to financing. Dr. Fernando Tallarico, P.Geo., FSEG, Chief Executive Officer and Chairman, stated that the soil dataset at Boa Vista supports the exploration model and justifies further drilling. The company provided detailed figures and sample IDs for all significant results, including the number of samples above key thresholds for TREO and gallium. The announcement includes references to previous reporting dates for gallium and yttrium results and outlines the next steps for exploration at both targets.

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

(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.
