Critical Metals Corp. (Nasdaq: CRML) a leading critical minerals mining company, today announced that it has received the final assay results from the 2025 drilling program at Area B and the Fjord Deposit at the Tanbreez Rare Earths Project in Greenland.

Key Highlights

Area B – Extent of mineralization:

Broad-spaced drilling results successfully demonstrate significant and extensive mineralisation potential across Area B, located immediately adjacent to the eastern margin of the Hill Zone Deposit (refer to ASX announcements dated 16 December 2025 and 15 January 2026, Figure 2).

Fjord Deposit – Extent of mineralization:

The Fjord area remains open along strike, with mineralization consistently confirmed near surface and demonstrating strong lateral and vertical continuity (refer to ASX announcements dated 16 December 2025 and 15 January 2026, Figure 2).

Resource growth potential:

The 2025 Fjord and Upper Fjord drilling results provide a strong indication of potential for resource growth and extension drilling for 2026 currently being planned.

Grade profile:

Total Rare Earth Oxide (TREO+Y) grades from the 2025 diamond drilling range from 0.40% to 0.47%, with heavy rare earth oxides (HREO) comprising approximately 26–27% of TREO+Y

Tony Sage, Chief Executive Officer of Critical Metals Corp., commented:

“I am very encouraged by the 2025 deep diamond drilling results, which continue to demonstrate meaningful extensions to our known Mineral Resource and confirm consistent rare earth mineralisation across the Fjord, Upper Fjord, Hill and now, Area B zone. These results enhance our confidence in the broader REE potential of the Tanbreez Deposit.

Importantly, the new assay data is expected to add further mineralised tonnage to the existing Hill and Fjord Deposits, supporting a potential uplift in scale and continuity across a significantly larger project footprint. This reinforces Tanbreez as a strategic, long‑life rare earth asset.

Our team is now progressing extension and infill drilling programs for the 2026 field season, focused on optimising future pit designs and advancing Mineral Resource studies. These next steps are aimed at de‑risking the project and positioning Tanbreez for future development milestones.”

New results are as follows.

Area B – Geological context and exploration results

Area B is located to the east-northeast of the Hill Deposit and spans an approximately 1,750 metre corridor of highly prospective geology. All drilling completed in 2025 within this area has returned broad intervals of rare earth mineralization, with TREO+Y grades typically ranging from ~0.35% to ~0.77%.

Drill holes 25-D17, 25-D13, 25-D10 and 25-D09 formed part of a reconnaissance drilling program designed to assess the prospectivity within this eastern extension of the Hill Deposit.

While the current drilling pattern remains widely spaced, results to date indicate strong geological and grade continuity across the corridor. This continuity highlights significant laterally extensive mineralization potential within Area B, which is positioned immediately adjacent to the eastern margin of the Hill Zone Deposit.

In addition, results have now been returned for the final 2025 drillhole at the Fjord deposit.

Fjord Deposit – Final 2025 drill results

Hole 25-D14

16.5m @ 0.4003 TREOY (25.02% HREO), 96 ppm Ga2O5, 274ppm HfO2, 1485ppm CeO2, 1125ppm Nb2O5 from 0.5m

38.0m @ 0.3801 TREOY (26.59% HREO), 84 ppm Ga2O5, 311ppm HfO2, 1381ppm CeO2, 1259ppm Nb2O5 from 21.0m

Hole 25-D15

55.5m @ 0.406 TREOY (26.02% HREO), 95 ppm Ga2O5, 325ppm HfO2, 1491ppm CeO2, 1307ppm Nb2O5 from 2.0m

Holes 25‑D14 and 25‑D15 are located at the northeastern end of the Fjord Deposit and confirm that mineralization remains open along strike. The assay results are consistent with previously reported drilling in this area and are expected to support preparation of a revised Mineral Resource Estimate, as well as the advancement of subsequent mine planning studies (refer to Table 1).

The assay results continue to demonstrate consistent rare earth grades and highlight the presence of strategic metals, including gallium, hafnium, cerium, and yttrium. These outcomes further reinforce Tanbreez’s status as a globally significant peralkaline-hosted rare earth system with scale potential and exposure to multiple strategic metals exposure.

Details of the 2025 drilling program are provided in Table 1 (collar information), with mineralized greater than >0.3% TREO+Y listed in Appendix 2, individual assay results provided in Appendix 3, and supporting geological interpretations presented in Figures 3, 4, and 5.

Area B and Hill Zone Deposit Tie-in Zone

Drill holes 25‑D17, 25‑D13, 25‑D10 and 25‑D09 formed part of a reconnaissance program designed to assess the prospectivity east‑northeast of the Hill Deposit. Although the drill spacing remains broad, results clearly indicate significant laterally extensive mineralization potential across Area B, whis is located immediately adjacent to the eastern margin of the Hill Zone Deposit.

Based on the results reported in this announcement, additional drilling across Area B and the Upper Fjord area is considered warranted to further define mineralized scale, continuity and potential resource growth.

Results from Area B, together with the broader 2024 and 2025 drilling programs, demonstrate TREO+Y grades ranging from approximately 0.35% to 0.77%, with an average heavy rare earth oxide (HREO) content of approximately 25.7%.

Grade Summary – Area B 2025 Drilling

• Total Rare Earth Oxide + Yttrium (TREO+Y): ranges between approximately 0.35%–0.61%.
• Heavy Rare Earth Oxide (HREO) proportion: ranges between approximately 21–27% of TREO+Y.
• Strategic and associated elements: Gallium oxide (~99 ppm), hafnium oxide (~292 ppm), yttrium oxide (~690 ppm), and cerium oxide (~1,646 ppm) are consistently present, together with zirconium oxide (0.9%–2.4%), niobium (~1,154ppm), and tantalum (~85ppm).

Reporting and Methodology Notes

• TREO+Y represents the sum of La₂O₃, CeO₂, Pr₂O₃, Nd₂O₃, Sm₂O₃, Eu₂O₃, Gd₂O₃, Tb₄O₇, Dy₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Yb₂O₃, Lu₂O₃, and Y₂O₃.
• A minimum downhole intercept width of 2m has been applied.
• No economic weighting has been applied to the reported results.
• A grade cut-off of 3,000ppm for TREO+Y has been applied with no metal equivalence calculation.
• All drilling and assay results, including both higher and lower grade intervals, are reported to ensure balanced and transparent disclosure.

Next Steps

The Company is undertaking a detailed review of several optimization strategies, which will be integrated with the advanced planning currently underway for the 2026 field season.
