Critical Metals Corp CRML NASDAQ – Announces Exceptionally High Grades of both Gallium & Rare Earth Elements Results at its Tanbreez Project in Greenland

NEW YORK, Aug. 04, 2025 (GLOBE NEWSWIRE) -- Critical Metals Corp. (Nasdaq: CRML) (“Critical Metals Corp” or the “Company”), a leading critical minerals mining company, is pleased to report outstanding assay results from recent as well as historical diamond drilling programs in southern Greenland. Commenting on the assay results, Tony Sage, CEO and Executive Chairman of the Company, said: “These exceptional results underscore the strategic value of Tanbreez as a rare earth and gallium project with scale, grade, and a high proportion of critical heavy rare earths. With China's ban on gallium exports to the United States, securing domestic sources of these critical minerals has become paramount for U.S. defense capabilities and national security. Our gallium results, combined with our rare earth grades, position Tanbreez as a strategically important asset for Western supply chains. The progress we've made, processing all 2024 drill cores, submitting 50% of samples for assay, and already completing over 1,200 meters of drilling as part of our 2025 Fjord Resource Upgrade program, puts us in a strong position to build on our significant resource base. With further assays pending and more drilling underway, we see strong potential to grow the scale and world class nature of the project's mineral inventory." TANBREEZ PROJECT DRILLING HIGHLIGHTS INCLUDE: New diamond drill assay results from ten holes: Gallium Oxide from 80 ppm to 140 ppmTREO range from 0.32% to 0.89%, with 27% HREOHoles drilled in 2010 within the Hill Deposit Mineral Resource EstimateAssays were for partially sampled holes; remaining sections planned These results add to the previously announced high-grade gallium results of up to 147 ppm Ga₂O₃ discovered at Area G, released on November 26, 2024 and available at this link. Summary of Tanbreez historic drilling results confirming High-Grade TREO 0.38% to 0.51% with 28% HREO at the Fjord Deposit and 0.42% to 0.48% with 26% HREO at the Hill DepositAll 2024 drill cores processed, with approximately 50% of samples in ALS Perth for assaying2025 Fjord Resource Upgrade Diamond Drilling program - five holes completed to date for 1,250 meters. Figure 1. View of the Tanbreez Project and the exploration Team 2025 New Assay Results from 2010 drilling at the Hill Deposit Ten diamond drill holes that were drilled in 2010 at the upper layer of the Hill Deposit were assayed for the first time by ALS Metallurgical in June 2025 for a full suite of rare earth elements and other metals including gallium. The Company notes that the assaying of historical drill cores from the Rimbal period (2007-2013) is nearing completion, and future news flow will primarily consist of current drilling results from the 2024-2025 campaigns. The collar positions and weighted average assays for each hole are shown in tables 1 and 2. Weighting was based on the sum of drill intercept length multiplied by the assay value divided by the total length. All holes are vertical and represent true thickness of the kakortokite. The drill hole samples were used for geochemical and geotechnical analysis, with selected intervals sent to the laboratory. The company will assay the remaining sections at a later stage. Refer to Table 1 and 2, and JORC Table 1, Appendix 2 and 3.

Fjord and Hill Deposits and 2025 Diamond Drilling Program Figure 3. Diamond Drill Hole DDH25-02, July 2025 Current 2025 exploration program On 20 January 2025, the Company announced the REE drilling results from the 2024 diamond drilling program conducted over the Fjord prospect at the Tanbreez Project. The drilling program consisted of 16 holes with a total cumulative length of up to 2,200 m. This confirmatory drill program was designed to optimize the resource for future production capacity and to extend the mine life of the Tanbreez Project. Additional 2024 diamond drilling core samples have been processed for assaying with 7 drill holes awaiting reporting. The results of these assays will be released once ALS Metallurgical in Perth complete the ICP Fusion analysis for REE, HREE and associated metal oxides, including gallium oxide, which is expected to occur by the middle of September. Core samples from a further 8 diamond holes are in transit from Greenland to Perth, with results expected in the middle of October. The Company recently announced a series of historical diamond drilling results on 28 March 2025, 12 May 2025, 20 May 2025 and 11 June 2025 proving a compelling high-grade TREO and HREO comparison results for deep diamond drill holes to the results for 2024 drilling, (see Tables 1 and 2 and Figure 4).

Weighted averages were calculated by length × assay / total length per interval, as stated. Diamond Drill Hole Sampling Parameters Sampling over the 10 diamond holes was taken over random intervals for the 10 diamond drill holes with reference to geotechnical and stratigraphical measurements. Collar data: All collar locations, RLs, azimuths, dips, and hole lengths have been presented in Table 1 of the report.Assay data: Table 2 in the report provides the full suite of weighted average downhole assay results for TREO, HREO, Ga₂O₃, and other elements.True widths: All drill holes are vertical (-90°) through sub-horizontal mineralized layers, so intersections are true widths.No cut-off grades or metal equivalents were applied. All assays are reported at face value.Weighted averages were calculated by length × assay / total length per interval, as stated. Figure 4. Location of the 2010 Diamond drill holes within the Hill Deposit Gallium and Outstanding TREO and HREO identified in the upper layer The reported range of gallium oxide (Ga₂O₃) of 80 ppm to 140 ppm from the ten drill holes in the Hill Deposit is notable, particularly for a bulk-tonnage alkaline intrusive system. While not typically the primary economic driver in REE deposits, gallium at this concentration exceeds average crustal abundance (~17 ppm Ga), making it anomalous and potentially significant. It is commonly recovered as a by-product of bauxite or zinc processing, but occurrences in syenitic rocks or eudialyte-hosted REE systems are less common and commercially interesting. The gallium oxide results at this concentration may justify metallurgical evaluation for potential recovery as a minor by-product from eudialyte. If gallium is hosted within eudialyte, it may report to the eudialyte concentrate and be extractable downstream. Gallium is on multiple national critical minerals lists (e.g., EU, US, Australia), enhancing the strategic appeal of Tanbreez.TREO range from 0.29% to 0.89%, with 27% HREO is significant because it represents a higher grade than previously reported for the upper zone. The drilling results for Diamond Hole A1-24 were: 0.47%TREO (including 27% averaged heavy rare earth (HREO),1.82% ZrO2 “zircon oxide”,131ppm Ta2O “tantalum pentoxide”,1,852ppm Nb2O5 “niobium pentoxide”,394ppm HfO2 “hafnium oxide”,102ppm Ga2O3 “gallium oxide”.
