FCM Completes Zigzag Earn-In and Secures 80% Interest in Strategic Critical Minerals Project
First Class Metals PLC the UK listed company focused on the discovery of economic metal deposits across its exploration properties in Ontario, Canada, is pleased to announce that it has completed all obligations under the Zigzag Option Agreement originally entered into with Nuinsco Resources Limited (“Nuinsco”) in March 2023.
Completion of the final option requirements results in FCM earning an 80% interest in the Zigzag Lithium-Critical Minerals Project (“Zigzag” or “Zigzag Project”) located within the highly prospective Seymour-Falcon pegmatite corridor of northwestern Ontario. As provided for under the terms of the agreement, Zigzag will now transition into a Joint Venture between FCM (80%) and Nuinsco (20%).
Highlights
• FCM has completed all cash, share and exploration expenditure commitments required under the Zigzag earn-in agreement.
• FCM has earned an 80% interest in the Zigzag Project and now assumes control of the asset.
• Project ownership now transitions into an 80:20 Joint Venture between FCM and Nuinsco.
• Zigzag hosts drill-confirmed lithium mineralisation with intersections including:
· 4.3m @ 1.65% Li₂O
· 5.0m @ 1.50% Li₂O
· 6.5m @ 1.09% Li₂O
and remains open along strike and at depth.
• Drilling has also confirmed the presence of significant multiple critical minerals including tantalum, rubidium, caesium and gallium.
• FCM is now evaluating a bulk sampling programme and metallurgical test work to better define potential recoveries.
• The project is situated approximately 10km from Green Technology Metals’ Seymour Project (ASX-GT1) and proposed lithium processing infrastructure.
• Improving lithium market fundamentals continue to support renewed interest in quality hard-rock lithium assets.
Strategic Importance of Zigzag
Since acquiring the option in March 2023, FCM has systematically advanced the Zigzag Project through surface sampling, channel sampling, geochemical surveys and its inaugural drilling programme.
The results confirmed significant spodumene-bearing pegmatite mineralisation, validated historic exploration data and demonstrated the potential for additional discoveries along strike and within parallel structures identified through geochemical surveys.
Importantly, Zigzag is not solely a lithium project. Drilling confirmed elevated levels of tantalum, rubidium, caesium and gallium, all recognised critical minerals with strategic importance to advanced technologies, energy storage systems and defence applications. These minerals have the potential to provide meaningful by-product value in any future development scenario.
The project is located within one of Canada’s emerging hard-rock lithium districts and benefits from proximity to Green Technology Metals’ Seymour Project, where development activities continue to advance. The Board believes this regional development significantly enhances the strategic value of the Zigzag Project through the potential future availability of shared infrastructure, processing solutions and regional expertise.
Next Steps
With the earn-in phase now complete and operational control established, FCM intends to focus on metallurgical test work on a large representative sample to better understand lithium and critical metal recovery characteristics
The objective of this work programme will be to better understand lithium recoveries, evaluate the contribution of associated critical minerals and assess potential development pathways for the project.
The Board believes the combination of confirmed lithium mineralisation, multiple critical metal credits, strategic location and improving lithium market conditions provide a compelling platform from which to unlock additional value at Zigzag.
James Knowles, Executive Chairman of First Class Metals, commented:
“”The completion of the Zigzag earn-in secures FCM’s 80% interest and operational control of a strategically located lithium and critical minerals asset. With drill-confirmed lithium mineralisation, valuable critical metal credits, improving lithium market fundamentals and proximity to planned regional processing infrastructure, we believe Zigzag has significant untapped potential. Our immediate focus is advancing metallurgical test work on a large representative sample to better understand lithium and critical metal recovery characteristics and further evaluate the opportunity at Zigzag.”
