When we talk about the clean energy transition, lithium, nickel, and rare earths steal the headlines. But tucked deep inside the supply chain of EVs and advanced manufacturing is a critical mineral you might not have heard of—fluorspar.
The thematic for commodity investing has recently been:
- Commodity in high demand for new technology applications
- Supply squeeze and lack of new developments
- Price action reflecting the supply shock.
As Western economies scramble to secure independent supply chains, fluorspar has quietly earned "critical mineral" status and falls into the sovereign ownership and supply shock narrative.
Here are the fast facts on fluorspar, and why stocks with large fluorspar resources such as Mont Royal Resources (ASX: MRZ) should be on your watchlist.
The Fast Facts: What is Fluorspar?
Fluorspar (or fluorite) is a colourful industrial mineral composed of calcium and fluorine (CaF2).
It is sold in two main grades, and both are essential to modern industry:
- Acid Grade (Acidspar): This is the premium, high-purity stuff, containing 97% or more CaF2. Acidspar dominates the market, accounting for roughly 70% of total global usage. It is the essential precursor for producing hydrofluoric acid.
- The EV Connection: Acidspar is a critical, non-replaceable ingredient used to manufacture lithium hexafluorophosphate (LiPF6)—the core electrolyte that makes lithium-ion batteries work.
- Metallurgical Grade (Metspar): This grade contains between 60% and 85% CaF2. It is heavily relied upon by the steel and cement industries. Metspar acts as a crucial flux to lower melting points and easily strip out impurities like sulfur during smelting.
The Opportunity
The fluorspar market is expanding rapidly, but the global supply chain is flashing warning signs.
- Booming Demand: The global fluorspar market was valued at US$3.67 billion in 2023 and is forecasted to hit US$4.91 billion by 2030.
- China's Stranglehold: China currently controls over 60% of the world's fluorspar production.
- The Squeeze: As China’s domestic EV and advanced tech sectors expand, they are consuming more of their own supply.
- Rising Prices: Because of this tightening global supply, fluorspar prices have been experiencing a steady upward trend since 2021.
Western economies desperately need to decouple from Chinese dominance and secure their own Tier-1 fluorspar assets.
Mont Royal Resources
Following a strategic merger with Commerce Resources in late 2025, Mont Royal controls the world-class Ashram Rare Earths & Fluorspar Project in Nunavik, Québec.
Ashram is already famous for its massive rare earth element (REE) footprint , but it is the project's fluorspar potential that makes MRZ a unique investment proposition.
Here is why MRZ stands out:
- Ashram is a dual commodity narrative of TREO and Fluorspar, The massive deposit features a consolidated Indicated resource of 73.2Mt at 1.89% TREO and a significant 6.6% calcium fluoride, alongside an Inferred resource of 131.1Mt at 4.0% calcium fluoride.
- Mont Royal is evaluating a dedicated fluorspar processing circuit. By extracting fluorspar alongside rare earths, the company is unlocking a dual revenue streams; which increases the NPV of the project.
- The metallurgy has already been de-risked. Test work proves the fluorspar at Ashram can be upgraded to an impressive 98.0% CaF2 concentrate, clearing the 97% hurdle required to sell into the premium, EV-driven acidspar market.
- The project is located in Québec, a Tier-1 mining jurisdiction. Crucially, Québec’s massive aluminium smelting industry consumes up to 200,000 tonnes of calcium fluoride annually. This gives MRZ a massive, hungry domestic buyer right on its doorstep, bypassing complex global shipping logistics.
The Bottom Line
Mont Royal Resources offers a rare "two-for-one" value proposition.
Whether you are a rare earths bull looking for the next major NdPr producer, or a strategic investor hunting for the emerging supply squeeze in the fluorspar market, MRZ covers both base via a massive, large scale project in a tier-1 jurisdiction.
Treating fluorspar as a high-margin co-product structurally de-risks the operation and boosts overall profitability.
For small cap investors, MRZ represents a unique opportunity to gain exposure to two critical clean-energy supply chains from a single, globally significant asset.
