Lithium in Alberta is dissolved in hot, salty formation water deep below the province’s oil and gas fields, not in rock at the surface. The Alberta Geological Survey has recorded up to 140 mg/L lithium in Devonian reef aquifers around Fox Creek, and the province now regulates these “brine-hosted minerals” under their own law and leases. Elsewhere in Canada, lithium comes from pegmatites, and that is where every Canada lithium mine operating today sits.

The national picture comes from Natural Resources Canada’s lithium facts. On its 2024 data, Canada held 1,336,178 tonnes of lithium in reserves, sixth in the world with 4.4% of the total, and 6.5 million tonnes of lithium in resources: 2.5 million in hard rock and 4.0 million in brines and wastewaters. Two operating mines produced 5,983 tonnes of lithium in 2024, seventh in the world. NRCan updates these figures periodically, so check the page for a newer year. For how brine and pegmatite deposits compare in general, see our guide to the main lithium deposit types.

“About 60% of Canada’s identified lithium resource is in brines, yet every operating mine is a pegmatite, on NRCan’s figures.”

Lithium in Alberta: the Devonian brines

The key public study is the Alberta Geological Survey’s Open File Report 2011-10 on lithium-rich formation water. It reports that Devonian formation waters produced with oil and gas in the Fox Creek area of west-central Alberta contain up to 140 mg/L lithium, in the Leduc Formation (Woodbend Group) and the Swan Hills Formation (Beaverhill Lake Group), at depths of roughly 2,500 to 3,900 m. For context, the average lithium in Alberta formation waters across 1,511 analyses was 10 mg/L and the median only 0.2 mg/L.

The same brines are enriched in other elements too, with potassium up to 8,000 mg/L, boron up to 270 mg/L and bromine up to 410 mg/L, which is why the survey noted industry interest in recovering several products at once. The report also mentions an earlier historical resource estimate for the Swan Hills, Leduc and Beaverhill Lake aquifers that was not prepared under NI 43-101. Treat numbers like that as background, not as a resource.

Why Alberta lithium deposits are different

Alberta lithium deposits are not salars. They are closer to the oilfield brines the USGS describes in the Smackover Formation of the US Gulf Coast: deep, warm water in carbonate reservoirs, reached by wells rather than ponds. That changes almost everything about exploration. The data come from existing oil and gas wells, the key questions are reservoir volume, permeability and how much water can be pumped and reinjected, and the lithium has to be recovered by direct extraction rather than solar evaporation. For comparison, see our guides to Argentina’s salars and the lithium triangle and to US lithium brines, clays and pegmatites.

• Where: west-central Alberta, around Fox Creek, in Devonian reef and carbonate aquifers.
• How deep: about 2,500 to 3,900 m in the areas the survey studied.
• How rich: up to 140 mg/L lithium, with potassium, boron and bromine as possible co-products.
• What it needs: reservoir data, brine chemistry, pumping and reinjection design, and a direct lithium extraction process.

A first programme for lithium in Alberta

Most work on lithium in Alberta starts at a desk, not in the field, because the brine has already been brought to surface for decades by oil and gas operators. A sensible first programme runs in this order, and each step narrows the ground before any new well is drilled.

1. Compile existing data. Produced-water analyses, well logs, core and pressure data for the target formations. The Alberta Geological Survey’s lithium dataset and reports are the public starting point.
2. Map the reservoir. Reef and carbonate buildups in the Leduc and Swan Hills formations vary in thickness and porosity. The lithium only matters where the reservoir can deliver volume.
3. Sample fresh brine. Take new samples from producing or re-entered wells, formation by formation, with a chain of custody and certified labs.
4. Test extraction. Run bench and pilot tests of direct lithium extraction on real brine, including the potassium, boron and magnesium that come with it.
5. Secure rights and approvals. Post and bid for brine-hosted mineral leases, then apply to the AER for well and facility licences.

The order matters because a strong lithium number from one old water analysis can fall apart once fresh samples are taken or once the reservoir turns out to be thin. For lithium in Alberta, the reservoir model is the project; the grade is one input to it.

Alberta and Saskatchewan compared

Both provinces host brine lithium in deep sedimentary formations, and both publish public data. The differences are in the rules and the rock. Lithium in Alberta sits mainly in Devonian reef aquifers studied by the AGS around Fox Creek, under a dedicated brine-hosted minerals regime run by the AER since 2023. In Saskatchewan, the provincial brine sampling project has focused on Ordovician to Mississippian strata including the Duperow and Torquay formations, and the province points explorers to its own Lithium Guidebook. Anyone comparing projects across the border should compare reservoir quality and permitting paths, not just the best lithium assay.

Who regulates lithium in Alberta

Alberta rebuilt the rules around lithium in a short period. According to the province’s minerals strategy page, a new regulation modernising tenure for metallic and industrial minerals took effect on 1 January 2023, and the Mineral Resource Development Act came into force for brine-hosted minerals on 1 March 2023 and for rock-hosted minerals on 28 February 2024. The Alberta Energy Regulator became the life-cycle regulator of brine-hosted minerals on 1 March 2023 and publishes a guide to the Directive 090 application process for brine-hosted resource development.

Mineral rights are a separate step. The province’s minerals permits and leasing overview says new brine-hosted mineral leases are issued through a public offering: companies or individuals request that land be posted, bids are placed in the Electronic Transfer System (ETS), and the application fee, first year’s rent and bonus are taken from the successful bidder’s account once rights are issued. A brine-hosted minerals lease has a 10-year initial term and can continue indefinitely if producing.

Fees and rents are as published by the Government of Alberta at the time of writing and exclude GST; confirm them on the province’s page before bidding. For rock-hosted permits, the same page sets assessment spending of $7/ha in the first two-year period, $13/ha in periods two and three, and $20/ha after that.

Lithium in Saskatchewan

Lithium in Saskatchewan follows the same brine model further east. The Government of Saskatchewan’s lithium page describes a provincial brine sampling project that analysed formation brines from Ordovician to Mississippian strata in southern Saskatchewan, including wells in the Duperow and Torquay formations, and it publishes a Lithium Guidebook on the requirements for exploration and operations. Questions go to the Ministry of Energy and Resources.

Canada lithium deposits in pegmatites: Manitoba, Quebec and Ontario

Canada’s hard-rock lithium is mostly Neoarchean, in the Canadian Shield. The USGS pegmatite deposit model lists Tanco in Manitoba, several Ontario pegmatites and the Quebec Lithium Corporation pegmatite among its Neoarchean examples, and NRCan counts advanced lithium projects in Ontario, Quebec, Manitoba, Alberta, Nova Scotia and Saskatchewan.

Manitoba: Tanco

Tanco, at Bernic Lake in Manitoba, is one of the world’s classic lithium deposits. The USGS pegmatite model describes it as a sub-horizontal, lens-shaped, zoned petalite pegmatite about 1,520 m by 1,060 m by 100 m, with economic lithium, cesium and tantalum, mined underground by room-and-pillar methods, and the world’s primary source of cesium. NRCan lists the TANCO mine as producing lithium since late 2021.

Lithium in Quebec

The USGS lithium paper notes that some pegmatites in Quebec contain large reserves of lithium that have not yet been mined. NRCan lists the North American Lithium operation near Val-d’Or, which restarted in March 2023, as one of Canada’s two operating mines, and the Whabouchi mine as idle since 2019 with a planned restart. Quebec grants exploration rights as map-designated claims, formally exclusive exploration rights, through the provincial ministry’s GESTIM system.

Lithium in Ontario and the Thunder Bay district

Ontario’s best-documented lithium field is Georgia Lake in the Thunder Bay Mining District. The Ontario Mineral Inventory record for the Jackpot pegmatites places them about 140 km north-east of Thunder Bay, staked in 1955 when 32 diamond holes were drilled, and redrilled with 61 holes in 2017 and 2018. It is a good example of how many Canadian lithium deposits work: known for decades, then re-examined when prices and demand changed.

Lithium in Nova Scotia and Newfoundland

NRCan includes Nova Scotia in its list of provinces with advanced lithium projects. Lithium in Newfoundland and Labrador does not appear in NRCan’s list of advanced projects, so any claims there should be treated as early-stage exploration until drilling says otherwise.

Canadian lithium deposits in numbers

Two agencies publish Canadian lithium figures, and they differ slightly. The USGS 2026 summary estimates Canadian output at 4,820 tonnes of lithium in 2024 and 5,600 in 2025, puts reserves at 1.6 million tonnes and measured and indicated resources at 8.1 million tonnes, and counts two mineral operations in Canada among the main world sources. NRCan’s 2024 production figure is 5,983 tonnes. The gap comes from different bases and estimation dates; quote the source and year with any number you use.

USGS reserve estimates for Canada have moved quickly, from 930,000 tonnes in the 2024 edition to 1.2 million in 2025 and 1.6 million in 2026, as companies published new studies. Those revisions reflect work on known deposits, not new discoveries, which is one reason lithium exploration Canada programmes still target extensions of known pegmatite fields.

What the numbers mean for a claim holder

Canada mined about 2.5% of the world’s lithium in 2024 on NRCan’s count while holding 4.4% of reserves, and most of its resource is in brines that are not yet producing. For a claim holder, that gap cuts two ways. On the Shield, a new Canada lithium mine competes for capital with expansions at the operations that already exist, so a pegmatite discovery needs grade, width and simple mineralogy to stand out. In the brine provinces, the resource is large but spread thin in solution, so the winners will be the reservoirs that flow best and the extraction processes that work on real brine at scale.

Either way, the first question from a partner or buyer will be the same: what has been measured on this ground, by whom, and when. Well-organised public data, fresh samples and a clear map of targets answer it faster than any headline tonnage. That is also where early engagement with Indigenous communities and local landholders pays off, because access and consent decide whether a good target can ever be drilled.

Lithium exploration in Canada: how programmes differ

A lithium exploration Canada budget looks completely different on each side of the Shield edge. For pegmatites, the USGS model’s guidance holds: find the fertile, peraluminous granite, then search within about 10 km for the most fractionated dykes. Airborne magnetics helps separate granite phases; our guide to aeromagnetic and ground magnetic surveys explains how. Glacial cover is the main local complication, because till can hide a dyke completely.

For brines, including lithium in Alberta, the work starts with data that already exists: oil and gas wells, logs and produced-water chemistry. Sampling programmes then test concentrations formation by formation, and hydrogeological models estimate how much brine a reservoir can deliver and accept back. The lithium in Alberta story is as much about reservoir engineering as geology.

1. Pegmatite belts: compile maps and assessment files, fly or buy magnetics, map outcrops and glacial dispersal, sample soils or till, then trench and drill.
2. Brine basins: compile well and water data, sample produced water, test formations, model the reservoir, then run a pilot with direct extraction.
3. Both: engage early with Indigenous communities and landholders, and record environmental baselines before ground work starts.

Common mistakes on Canadian lithium projects

• Quoting a single old water analysis as if it were a grade for a whole reservoir. Lithium in Alberta brines varies by formation and by well.
• Ignoring reinjection. A brine project has to put the water back; capacity to do so can limit output as much as the lithium grade.
• Treating historical estimates as resources. Government reports sometimes quote older figures that were never prepared under NI 43-101.
• Drilling pegmatites without mapping the till. In glaciated ground, a soil anomaly may have moved hundreds of metres from its source.
• Assaying for lithium only in Shield pegmatites, and missing the tantalum and cesium that made Tanco valuable.

Canadian lithium terms in plain English

Brine-hosted mineral

Alberta’s legal term for minerals such as lithium dissolved in deep saline groundwater, regulated by the AER since March 2023.

Formation water

Water naturally present in a rock formation, often produced with oil and gas. It is the source of lithium in Alberta and Saskatchewan brine projects.

Direct lithium extraction

Processes that pull lithium out of brine chemically, instead of evaporating it in ponds, which is not possible in Canada’s climate.

Petalite

A lithium silicate with about 2% lithium, the main lithium mineral at Tanco.

Map designation

Quebec’s online method of acquiring an exclusive exploration right, done through GESTIM.

How satellite screening fits a Canadian lithium programme

On the Shield, satellite data helps map outcrop, structure, glacial landforms and the pattern of dyke swarms over a large claim block before crews fly in for a short season. In brine country, it is more useful for surface access, infrastructure and environmental baselines than for the reservoir itself, which sits kilometres down. Our satellite-based mineral detection analyses multispectral and hyperspectral data over your boundary to flag target zones, alteration halos, faults and fractures; the wider method is covered in our guide to remote sensing for mineral exploration.

• Input: coordinates, KML/KMZ or a polygon, plus province and target mineral.
• Output: high-potential zones, prospectivity heatmaps, estimated location and depth ranges, geological interpretation, PDF and GIS files.
• ✔ Time and cost: 5–20 business days; early-exploration timelines cut from months to days and costs lowered by up to 80–85%.
• Premium+: TargetMax™ drilling-angle recommendations and 3D subsurface models.

We have scanned 100,000+ hectares for 20+ mineral types across 25+ countries. Targets are exploration targets to test by mapping, sampling and drilling, not resources.
