A 22% IRR and 30-year mine life land alongside a C$1.23bn capex bill.
Mont Royal Resources (ASX:MRZ) has put a sharper number on its Ashram Rare Earths and Fluorspar Project in Québec, and the headline economics are the kind that get a development-stage rare earths name back into the conversation. The updated Preliminary Economic Assessment delivers a post-tax NPV of C$2.03 billion at an 8% discount rate, a 22% post-tax IRR, and a 30-year mine life producing an average 17,466 tonnes of rare earth oxide a year.
About 4,035 tonnes of that annual output is NdPr, the magnet rare earths used in EVs, wind turbines and defence. That product mix is what Western buyers are actually short of, and Ashram now sits as one of the largest monazite-hosted deposits in North America.

The catch is the cheque. Initial capex lands at C$1.23 billion before the access road, and total life-of-mine capital runs to C$1.6 billion. Mont Royal’s current market cap is a long way south of those numbers, which is exactly why this PEA matters more for the funding conversations it enables than for the model itself.
The economics finally clear the bar for serious strategic interest
A 22% post-tax IRR and a 3.9-year payback on a 30-year asset is a credible return profile, especially for a project sitting in Québec with access to hydropower and a Tier-1 permitting regime. Life-of-mine EBITDA margin of 62.7% reflects a low strip ratio of 0.4 to 1 and the favourable monazite mineralogy.
C1 cash costs come in at C$17.99 per kilogram of saleable REO, with AISC just above at C$18.58. Those numbers are competitive against most non-Chinese rare earth developers we track, and they leave room for the project to remain profitable even under the downside REO basket scenarios in the sensitivity tables.
Mont Royal also factors in about C$342 million in refundable Clean Technology Manufacturing Investment Tax Credits into post-tax cash flows. That credit is real and codified in Canadian tax law, which is more than most rare earth projects can lean on for non-dilutive capital.
The C$1.23bn capex question is the entire investment debate
Mont Royal flags the obvious risk in its own announcement. The capital required is materially larger than the company’s ability to raise on the equity market without significant dilution or a strategic partner taking a chunk of the project.
Management points to Canadian and Québecois critical minerals funding programs, potential offtake-linked financing, and joint venture options as the credible paths. None of these are committed. The skeptical read is that the project’s strategic merit is now well established, but the gap between PEA economics and a financed PFS-stage development plan is where most rare earths stories quietly stall.
What strengthens the case here is the geopolitical backdrop. China accounted for roughly 77% of global mine production and around 90% of separation capacity in 2025, and Western governments have been actively writing cheques for projects that look like Ashram. Mont Royal needs one of those cheques to materialise inside the next 12 to 18 months.
What the resource base and product mix actually buy investors
The base case mine plan uses only about 25% of the current global resource, with 93% of the 30-year schedule sitting in the Indicated category. That gives the project genuine expansion optionality without relying on Inferred tonnes to make the numbers work.
Optional upside includes a potential fluorspar recovery circuit, the higher-grade BD-Zone that was excluded from the current resource, and the satellite Mallard target. Each of these could lift the value envelope but none of them are needed for the current PEA to stand.
We think the more important point is the product itself. Mixed rare earth carbonate at this scale and grade is a feedstock Western separation facilities genuinely need, and Adamas price forecasts assume meaningful uplift in Tb, Dy and NdPr through 2031 to 2035.
The Investors Takeaway for Mont Royal Resources
Mont Royal has done the technical work to position Ashram as a credible long-life North American rare earths supplier. The PFS is targeted to commence in the second half of this year, and that study is what offtake partners and government funding bodies will actually scrutinise.
What we will be watching is whether named strategic partners, offtake conversations, or government funding commitments emerge before the company has to come back to equity markets at scale. The PEA gives Mont Royal something concrete to negotiate against, but the share register’s experience over the next year depends entirely on how that negotiation goes.
