Assay Results Extend Swell Zone at Mavis Lake – Starting from Surface and Extending over 1km in Strike

Lithium exploration and project developer Critical Resources Limited (ASX:CRR) (“Critical Resources” or “the Company”) is pleased to report further outstanding assay results from the Mavis Lake Lithium Project in Ontario, Canada.


Highlights

  • Latest assay results from recent drilling at Mavis Lake have demonstrated continuity with previous, thick high-grade intercepts.
  • The high-grade mineralisation within the Swell Zone starts from surface and extends over 1 kilometer in strike from east to west.
  • Standout new assay results include:
    • Drill-hole MF23-226 with a Swell Zone intercept of 31.55m @ 1.06% Li2O from 205.6m down-hole, and an additional ‘Lower Zone’ high-grade intercept of 20.7m @ 1.44% Li2O from at 339.3m down-hole.
    • Multiple intercepts in drill-hole MF23-228, including:
      • 16.8m @ 1.18% Li2O from 177.05m down-hole,
      • 12.85m @ 1.39% Li2O from 208.1m down-hole, and
      • 14.85m @ 1.25% Li2O from 333.25m down-hole.
  • Multiple Project development workstreams continue including baseline environmental studies, metallurgical test work, mining studies and project economic analysis.
  • Results pending from Main Zone drilling at Mavis Lake and drill-target generation field work at the Project’s northern prospects.

The latest assays have confirmed and extended the recently discovered Swell Zone and, when integrated with previous drilling results, show a thick, high-grade mineralised structure, starting from surface and extending over 1km in strike, sitting oblique to the current Mineral Resource Estimate (MRE).

1km Strike Length of Swell Zone

Recent drilling has established an important connection between previous drilling results, validating the Swell Zone discovery and demonstrating substantial Resource upside.

Current assays confirm a significant, 1km strike of high-grade mineralisation, starting at surface (refer to Figure 2) in the east and plunging gently to the west. Significant assays are shown in Table 1 and full exploration results are provided in Appendix 1.

The results confirm substantial thicknesses of high-grade lithium spodumene mineralisation. Importantly, when incorporating historical drilling the Company has now achieved tight drill spacing (approximately 50m spacing). The thickness and continuity of the Swell Zone, commencing from surface, is expected to contribute to positive future mining economics.

Much of the Swell Zone mineralisation sits outside the current Inferred MRE for Mavis Lake and presents as an immediate opportunity for immediate Resource growth.

Lower Zone Identified

Drill Holes MF23-226, MF23-227, MF23-228 and MF23-229 have all continued to intersect a “Lower Zone” of high-grade mineralisation, with a standout intercept of MF23-226 of 20.7 metres at 1.44% Li2O.

This Lower Zone was not identified in the Maiden Mineral Resource Estimate and presents as another immediate opportunity for Resource growth.

The Lower Zone can be seen in context relative to the Mavis Lake Main Zone intercepts in Figure 3.

European Metals Receives US$36 Million Grant for Cinovec Lithium-Tin Project

European Metals Holdings (ASX:EMH,LSE:EMH,OTCQX:EMHXY) confirmed the approval of a US$36 million Just Transition Fund (JTF) grant for its Cinovec lithium-tin project on Monday (April 28).

The JTF is run by the European Commission, supporting projects that align with the economic diversification and reconversion of concerned territories such as Bulgaria, the Czech Republic and Hungary.

JTF states on its website that the number of supported projects varies annually, depending on the proposals. The grant also forms part of the European Union’s efforts to transition to clean energy and achieve climate goals.

Cinovec was chosen as it was designated as a strategic project under the Critical Raw Minerals Act in March, underlining its importance in Europe’s journey toward securing stable supply of critical raw minerals. It was also declared a strategic deposit by the Czech government, a designation that accelerates certain permitting processes.

"The grant funding will be utilised to fast track a number of critical path items with regards to the Cinovec Project,” commented European Metals Executive Chair Keith Coughlan in a press release. “This confirmation builds on recent project momentum and is another clear indicator of the support the European Union and the Czech government is willing to provide to assist in getting Cinovec into production in the timeliest manner possible."

Atlantic Appeals for Fiscal Re-evaluation for Ewoyaa Lithium Project

Atlantic Lithium (ASX:A11,LSE:AAL,OTCQX:ALLIF) is appealing to the Ghanaian government to re-evaluate fiscal terms regarding its flagship Ewoyaa lithium project, which is located in the country.

The company’s board of directors acknowledged media reports on the situation in a press release late last week, saying it wants to ensure the successful development of the asset.

Atlantic notes that lithium prices have significantly declined since the mining lease for Ewoyaa was granted in October 2023, and is urging officials to adjust fiscal terms based on current price levels. Lithium prices remained low in 2024, and the downtrend has continued in 2025, with some price segments falling to four year lows.

Adam Webb, head of battery raw materials at Benchmark Mineral Intelligence, said at the Benchmark Summit in March that lithium carbonate prices are expected to remain about where they are, at US$10,400 per metric ton.

“But if we look further ahead, from 2026 onwards, that market is switching into the deficit, albeit quite small to start with, and that will end up being supportive of prices,” he explained at the Toronto-based event.

Australian spot spodumene concentrate prices have also declined.

Starting the year at the US$990 per metric ton level, values contracted through the first quarter of 2025 and are now sitting at the US$765 level, a 23.5 percent drop from January 2024's price of US$1,000.

7 Biggest Lithium-mining Companies in 2025

For a long time, most of the world's lithium was produced by an oligopoly of US-listed producers. However, the sector has transformed significantly in recent years.

Interested investors should cast a wider net to look at global companies — in particular those listed in Australia and China, as companies in both countries have become major players in the industry.

While Australia has long been a top-producing country when it comes to lithium, China has risen quickly to become not only the top lithium processor and refiner, but also a major miner of the commodity. In fact, China was the third largest lithium-producing country in 2024 in terms of mine production, behind Australia and Chile.

Chinese companies are mining in other countries as well, including top producer Australia, where a few are part of major lithium joint ventures. For example, Australia’s largest lithium mine, Greenbushes, is owned and operated by Talison Lithium, which is 51 percent controlled by Tianqi Lithium Energy Australia, a joint venture between China’s Tianqi Lithium (SZSE:002466,HKEX:9696) and Australia’s IGO (ASX:IGO,OTC Pink:IPDGF). The remaining 49 percent stake in Talison is owned by Albemarle (NYSE:ALB). Joint ventures can offer investors different ways to get exposure to mines and jurisdictions.
