Grid Metals Advances Toward Maiden Cesium Resource at Manitoba’s Falcon West

• Cesium is exceptionally scarce with only three pollucite deposits have ever reached production anywhere in the world.
• Grid Metals has commissioned a maiden NI 43-101 mineral resource estimate for cesium and lithium at the Lucy South pegmatite with results expected in fall 2026.
• Avenir Minerals, a wholly-owned subsidiary of Agnico Eagle Mines Limited, holds a 15% interest in Falcon West following a C$3.75 million cash investment, with further options tied to the resource, PEA, and mine-plan milestones.
• The proposed processing method requires no tailings facility and no water using only crushing and X-ray ore sorting, with total project capex estimated under $10 million.
• Grid's broader Manitoba portfolio, including partner-funded projects with Teck Resources and Boliden, provides diversified exposure beyond the cesium story.

Grid Metals Corp. is closing in on a milestone few junior explorers ever reach: a maiden resource for a mineral almost nobody mines. The Manitoba-focused developer has commissioned SGS Canada Inc. to prepare a National Instrument 43-101 (NI 43-101) compliant mineral resource estimate (MRE) for the Lucy South pegmatite at its Falcon West property, with results expected this fall. It is a rare moment in a genuinely rare corner of the critical minerals market. Only three deposits of pollucite have ever gone into production worldwide, and the company now counts Avenir Minerals, a wholly-owned subsidiary of Agnico Eagle Mines Limited, as a joint-venture partner and shareholder.

President and CEO Robin Dunbar laid out why the company believes the cesium opportunity at Falcon West stands apart from the multi-commodity exploration Grid is better known for in southeastern Manitoba.

Project Overview: Like Running a Quarry

The Lucy South pegmatite sits within Falcon West, 130 km east of Winnipeg and directly off the Trans-Canada Highway. Mineralisation is shallow, ranging from under 2 metres to 40 metres below surface, and the cesium-rich core zone has been delineated over an area of 120 by 50 metres following completion of a 67-hole, 3,075-metre Phase 2 drill programme. Notable intercepts from the final Phase 2 assays include 2.75 m grading 5.44% Cs2O and 1.52% Li2O at hole LU26-60 (including 1.55 m at 8.49% Cs2O), and 0.88 m of 2.53% Cs2O at LU26-57.

Dunbar described the extraction process in strikingly simple terms: 

"There's no water used in the process. It's like running a quarry because if you find pollucite, you can put it through an ore sorter and you get a pile of material that you crush the rock, and a pile of rock gets spit out which is a saleable concentrate." 

No flotation circuit, no tailings facility, and an estimated total project capex under $10 million, a figure Dunbar benchmarked against Power Metals Corp's comparably scaled Case Lake operation in Ontario.

The Avenir Joint Venture

The deal structure underpinning Falcon West's near-term funding is arguably as important to the investment case as the geology. Avenir acquired an initial 15% interest in the Falcon West property for C$3,750,000 in cash with TSX Venture Exchange approval confirmed. Grid retains an 85% interest and operatorship.

The agreement grants Avenir the option to subscribe for up to 19.99% of Grid's issued and outstanding common shares, at a 10% premium to the 30-day volume-weighted average price, exercisable once the Lucy South MRE is published, meaning the forthcoming resource announcement doubles as a funding trigger. A separate Phase Two Option allows Avenir to acquire an additional 15% interest (30% total) in the property upon completion of a Preliminary Economic Assessment (PEA) or adoption of a mine plan, priced at 40% of the project's net present value at an 8% discount rate (NPV8%), calculated on a 100% project basis and applied to the 15% tranche.

Dunbar framed the partnership as validation as much as capital: 

"To bring them in are two things: one is funding but the other is a validation of the project. It validates our team because we're going to be running the project."

Cesium Market Dynamics

Cesium's investment case rests on scarcity that is difficult to overstate. Industry estimates cited in Grid's own market materials put the number of known pollucite deposits at roughly six, with only three (Tanco in Manitoba, Bikita in Zimbabwe, and Sinclair in Western Australia) having ever produced cesium ore. Sinomine's Tanco mine, Grid's neighbour in southeastern Manitoba, is believed to be the only cesium concentrate operation currently running.

Pricing is notably opaque. Grid's clearest data point comes from prior discussions with Tanco, which indicated a floor price of 300 per tonne for every 1% cesium content in ore, a benchmark Dunbar called conservative relative to the broader chemical market. Cesium carbonate itself trades at roughly $250,000 per tonne, up around 100% since summer 2025 and approximately ten times the price of lithium carbonate. Global annual demand is estimated at 15,000 tonnes of 20% Cs₂O concentrate, a market Albemarle moved to secure supply for in December 2025 by taking all offtake from Power Metals' Case Lake cesium project.

Catalysts and Resource Timeline

Grid's near-term calendar is dense. The maiden cesium and lithium MRE for Lucy South is targeted for this fall, to be followed by network engineering and mine-planning work, with permitting discussions running alongside. Dunbar was direct about the ambition: 

"We hope by this time next year, we have an economic study and if we don't have a permit, we're close to getting one for the mining." 

He attributed the compressed timeline to the absence of a water-intensive process and major fixed infrastructure requirements, comparing the permitting profile favourably to a quarry operation rather than a conventional mine.

Portfolio Optionality

Cesium is the headline story, but Falcon West sits within a considerably larger Manitoba land package. The Makwa nickel project is subject to an option and joint-venture agreement with Teck Resources Limited, under which Teck can earn up to a 70% interest by funding cumulative expenditures of C$15.7 million and cash payments of C$1.6 million. The Mayville copper project, 100%-owned by Grid, hosts a measured-and-indicated open-pit resource of 32 million tonnes grading 0.61% copper-equivalent. The Donner lithium project, 75%-owned, carries an inferred resource of 6.8 million tonnes grading 1.39% Li2O, with a toll-milling memorandum of understanding in place with the nearby Tanco plant. Thompson East, a Ni-Cu-PGM (nickel-copper-platinum group metals) target adjacent to the Thompson Nickel Belt, is optioned to Boliden, the Swedish multinational miner, which can earn an 80% interest by funding at least C$9.6 million in expenditures over four years.

Dunbar described the logic behind spreading exposure across commodities: 

"It's good to have multi-commodities when one commodity will go down and you're not orphaned immediately. However we're not a prospect generator, we always want to have one project where the majority of our resources and time are going."

Investment Thesis for Grid Metals

• Grid Metals is advancing one of a small handful of pollucite-hosted cesium discoveries globally, in a market where only three deposits have ever reached production.
• A maiden NI 43-101 resource for the Lucy South pegmatite, expected fall 2026, is a binary near-term catalyst that also triggers Avenir's option to increase its equity stake in Grid.
• Avenir Minerals, a subsidiary of Agnico Eagle, has committed C$3.75 million for an initial 15% project interest and can fund the project toward production through staged options tied to the resource, PEA, and mine-plan milestones.
• Processing economics are unusually simple for mining: crushing and ore sorting only, no tailings facility and no water use, with total project capex estimated under $10 million.
• Cesium carbonate pricing has roughly doubled since summer 2025, and Albemarle's December 2025 move to lock up Power Metals' Case Lake offtake signals active buyer-side competition for new supply.
• Monitor the fall 2026 MRE publication date closely, as it is the trigger for Avenir's equity subscription option and a likely re-rating catalyst given Grid's current $31 million market capitalisation.
• Portfolio optionality at Makwa (Teck), Mayville, Donner, and Thompson East (Boliden) provides diversified, partner-funded exposure to nickel, copper, and lithium alongside the cesium story.

Macro Thematic Analysis

Cesium occupies an unusual position in the critical minerals landscape: designated a critical mineral by both the United States and Canada, yet too small and too concentrated a market to attract the exploration capital flowing into lithium, copper, or rare earths. That scarcity of both the metal and the capital chasing it is precisely what Grid Metals is positioning against. With Sinomine controlling the vast majority of current processing capacity and only two major global buyers, Sinomine and Albemarle, a Western-jurisdiction, near-surface deposit backed by an Agnico Eagle subsidiary carries strategic weight beyond its modest scale. As Dunbar put it, describing the broader logic behind entering the market at all: 

"There is no new cesium concentrate on the world market and there's a real supply shortage currently. With the small amounts like we have at Falcon West, we believe will be snapped up very, very quickly in the market at a good price." 

Perovskite solar cells represent the most-cited emerging demand driver, alongside established uses in medical imaging, defence electronics, and atomic clocks. For a company sized at roughly $31 million, the combination of a binary resource catalyst, a well-capitalised partner, and a structurally undersupplied end market is the kind of setup that has historically preceded sharp re-ratings in the junior resource space, though it remains contingent on the resource itself delivering the grade and continuity the Phase 2 drilling has suggested.

TL;DR

Grid Metals has commissioned a maiden NI 43-101 resource for the Lucy South cesium-lithium pegmatite at Falcon West, Manitoba, expected fall 2026. Avenir Minerals, an Agnico Eagle subsidiary, holds 15% of the project after a C$3.75 million cash investment and can fund toward production through staged options tied to the resource, a PEA, and a mine plan. Cesium is exceptionally rare, only three deposits have ever produced ore, and pricing has roughly doubled since mid-2025. Processing requires no tailings and an estimated sub-$10 million capex, positioning Grid for potential near-term cash flow against a $31 million market cap.
