Insights

Mining Analyst

Critical Metals Corp's latest drilling results represent a significant positive development for the Tanbreez Rare Earth Project in Greenland. The historical deep drilling data reveals consistent high-grade rare earth mineralization extending to depths of 338m and 243m, far beyond the average 35m depth of previous drilling that formed the basis of their current resource estimate.

The drill results revealed 0.42-0.44% TREO (Total Rare Earth Oxides) with remarkably high heavy rare earth oxide content of 24-28% - this is particularly noteworthy as heavy rare earths typically command premium prices due to their applications in high-tech industries and global supply. The consistent mineralization across substantial distances (1,549m length with 372m width) strongly suggests the potential for significant resource expansion.

Beyond rare earths, the drilling confirmed economically interesting levels of gallium oxide (102-103ppm), a critical element for semiconductors, as well as zirconium, tantalum, niobium, and hafnium - all strategic metals with industrial applications. The lateral and depth continuity demonstrated by these results substantially de-risks the geological model and provides strong justification for the company's planned development activities.

The pending Preliminary Economic Assessment (Q2 2025) will be the next major catalyst, providing the first comprehensive economic framework for the project. With Critical Metals positioning to increase its stake to 92.5% (from current 42.5%) through a $10 million investment plus share issuance, the company is strategically aligning itself as a potential Western supplier of these critical materials - particularly significant given current global supply chain concerns around rare earth elements.

Financial Analyst

These drill results substantiate Critical Metals Corp's fundamental investment case by confirming significant resource expansion potential at Tanbreez. The consistency of high-grade mineralization across wide distances and to depths nearly 10 times greater than previously modeled suggests the current 45 million tonne resource (announced in March 2025) may represent just a fraction of the total deposit potential.

The exceptional 24-28% heavy rare earth content is particularly value-enhancing, as heavy rare earths like dysprosium and terbium can sell for multiples of the price of light rare earths. Additionally, the confirmed presence of economically significant concentrations of gallium oxide adds another valuable revenue stream - gallium being essential for semiconductor manufacturing and in increasingly short supply globally.

Critical Metals' staged acquisition structure ($10 million investment to increase ownership from 42.5% to 92.5%, plus $116 million in share issuance) provides a clear pathway to majority control while managing near-term capital requirements. The upcoming Preliminary Economic Assessment in Q2 2025 will be important for valuing this asset, as it will provide the first comprehensive financial framework including capital requirements, operating costs, and potential returns.

The strategic value of Western-controlled rare earth deposits cannot be overstated in the current geopolitical climate. With China dominating global rare earth processing and supply, projects like Tanbreez represent critical diversification opportunities for supply chains serving electrification, defense, and high-tech manufacturing. The deposit's scale, grade, and multi-element composition position it as a potentially world-class asset in Critical Metals' portfolio.

The announcement results for historical deep diamond drill holes DDH 7-14 drilled in 2007, and DX-01 drilled in 2010 were drilled by Rimbal P/L, which was the sole owner of the Tanbreez REE Project at that time.

Critical Metals Corp acquired a 42.5% interest in the Tanbreez Project in 2024 (which is expected to increase to 92.5% after Critical Metals Corp invests $US10m in the Tanbreez Project to further its development, and upon the issuance of an additional $116 million worth of newly issued shares of Critical Metals Corp to Rimbal) from the privately owned Australian Company Rimbal P/L (which had no obligation to publish or disclose drill results). The Company is now announcing for the first time historical drill hole data and assay results to further unlock the true potential of the Tanbreez project.

Critical Metals Corp recently announced its maiden SK1300 report for the Tanbreez Project of 45MT (consisting of 19.5 million metric tonnes of inferred resource and 25.4 million metric tonnes of indicated resource) containing 0.38% TREO including 27% contained HREO plus rare metal oxides.

Critical Metals Corp is still awaiting assay results from the September-November 2024 confirmation drilling program comprised of sixteen holes, with the first hole A1-24 reported January 2025, and expects to publish the remaining 15 diamond drill hole assay results when they become available.

The drilling results from A1-24 drilled 2024 confirmed a significant 40m deep intersection from outcropping surface mineralization of high-grade rare-earth oxide averaging:

• 4,722.51ppm (0.47%TREO) (including 26.96% averaged heavy rare earth (”HREO”),
• 1.82% ZrO₂ “zircon oxide”,
• 130.92ppm Ta₂O “tantalum pentoxide”,
• 1852.22ppm Nb₂O₅ “niobium pentoxide”,
• 393.68ppm HfO₂ “hafnium oxide”,
• 101.67ppm Ga₂O₃ “gallium oxide”.
  

The assay results from historical deep diamond drill holes DX-01 and D07-14 (that were drilled by Rimbal P/L in May 2007 and 2010) confirm similar average grades to drill hole A1-24.

Figure 1 Drillhole collar positions for deep diamond holes DX-O1 to 338m, D7-14 to 243m and A1-24 to 40m with the average assays results from surface. The length between drill holes is 1549 metres from A1-24 to DX-01 and 1037m from DX-01 to D7-14 with a 372m width between DX-01 and D7-14.

Figure 2: Deep Diamond Hole intersections containing high grade TREO average mineralization from surface to 338m in hole DX-0, to 243m in D7-014 and 40m in A1-24. The approximate dimensions between drillholes DX-01 and D7-14 is 1037m in length with a width of 372m. The thicker blue line annotations indicate mineralization is open at depth bellow drill holes DX-01 and D7-14 and not A1-24. The thinner blueline annotation indicates the 2025 extension drilling program target which may or may not contain economic mineralization until drilled and assayed.

The stratigraphic cross section was originally drafted in 2014 (by the previous owner Rimbal P/L) to log the stratigraphy, Kakortokite mineralogy and to estimate the potential resource at depth by outlining the thickness into the mineralized Kakortokite host rock.

The diamond drill hole DX-01 and D7-14 was sampled and logged by independent Geologists and supervised by Tanbreez Mining’s Greenland Chief Geologist, Mr. Hans Kristian Schønwandt, to JORC 2004 and 2012 QA - QC standards.

The processed core logs, core photos and core samples were shipped to Ultra Trace Laboratory in Perth Western Australia.

Historical Deep Hole Summary

The deep hole results present a compelling opportunity to extend mineralization with further deep infill drilling between both historical diamond holes and below into the existing Tanbreez Hill Zone Deposit of 22.31MT reported on 13 March 2025.

Diamond drill holes DX-01 and D7-014 were drilled for stratigraphic and mineralogical study, with assays confirming deep highly mineralized TREO averaging 0.42% with 24.5% HREE and 0.43% with 28% HREE to depths of 338m and 243m respectively contained within the Kakortokite host rock.

Both drill holes assayed similar results for the metal oxides including tantalum, niobium, zirconium, hafnium and gallium and correlate directly to the results for A1-24 of TREO 0.43% with 26.9% HREE.

Both drill holes A1-24 and DX-01 were terminated into the basal rock unit in a Tephri -Phonolite named Black Madona that contained only background mineralization.

Drillhole D7-14 was terminated in mineralization and further drilling will be required to confirm the true thickness beyond the 243m at the bottom of the drillhole D7-14.

Drill hole DX-01 was collared at surface and drilled to 338m within the Tanbreez Hill Zone Deposit containing 22.31 MT @ 0.33% TREO with 27% HREE and within a gridded area containing 49 RC holes and 46 diamond drill holes that were drilled to an average depth of 35m and used by Maynard and Associates in 2016 in reporting the MRE.

The drill results have a consistent average grade of mineralization for TREO and metal oxides of 0.43% between the three drillhole collars that span approximately 1549m length and 372m width with a higher priority placed over the area between DX-01 and D7-14 with a 1037m length and 372m width. The distance was measured from GPS coordinates between DX-01 to A1-24 m and is 1549m on a similar Northing with a width difference of 6m from the Easting.

The distance from GPS coordinates between drill holes DX-01 and D7-014 is 1037m and width of approximately 372m.

The distance from GPS coordinates between A1-24 and D7-014 is 512m and an approximate width of 372m.

The Ga203, gallium oxide for both diamond holes assayed A1-24 and DX-01, were 101.7ppm and 102.2ppm respectively and add a vital oxide credit to the TREO mixed concentrate adding to the project’s economic status. D7-014 was not assayed for gallium in 2007. The Company will submit sample pulp for assay in the coming months.

Next Steps

Critical Metals Corp is currently re-assaying historical pulps stored in Perth and Greenland from some of the existing 2007, 2010 and 2013 drill, rock chip and bulk sampling for confirmation and check assay reconciliation. The pulp will be analyzed by ALS Metallurgical Laboratory in Perth Western Australia and the results will be published when they become available.

Critical Metals Corp is currently reviewing all available data from the previous owner’s data base and will publish results upon third party and in house consultation.

Critical Metals Corp has engaged a third-party consultant who will report on the Preliminary Economic Assessment (PEA) for Tanbreez and is due for completion in the second quarter of 2025. The PEA Report is expected to cover the extensive economic and historical data on hand from the previous owner which will evaluate the economic potential for Tanbreez.
