Uranium Explorers Advance High-Grade Athabasca Uranium as Nuclear Demand Surges

Source: Streetwise Reports 08/20/2026

With electricity surging from artificial intelligence data centers, the case for new nuclear generation is lifting interest in uranium. Read about the special business model two explorers share as they search for the element in the Athabasca Basin.

Surging electricity demand from artificial intelligence data centers is strengthening the case for new nuclear generation and lifting interest in uranium projects such as NexGen Energy Ltd.’s (NXE:TSX; NXE:NYSE) Rook I in Saskatchewan, where mining major BHP Group Ltd. (BHP:NYSE; BHPLF:OTCPK) is in active dialogue with the developer, according to an August 17 report by Divya Rajagopal and Melanie Burton for Reuters.

The rapid growth of AI and power-hungry data centers is pushing utilities and governments to seek more reliable generation, while countries also look to diversify energy supplies following the Iran war, the report said.

NexGen Chief Executive Officer Leigh Curyer told Reuters the company is exchanging information and “talking regularly” with BHP about Rook I when asked whether the miner could take an equity position. NexGen began construction of what it expects to be one of the world’s largest uranium mines recently and plans to secure about US$1 billion of capital over the next nine months. Curyer pointed to BHP’s acquisition of a large land package near Rook I in the Athabasca Basin as a sign of its growing presence in the region.

The AI buildout is pushing the technology industry toward a new approach to securing power, with nuclear emerging as a critical source of around-the-clock generation, noted a June 2 report on the website Informed Clearly. Direct nuclear power-purchase agreements between major tech companies and reactor operators are reshaping how hyperscalers plan and finance energy, as data center electricity demand is expected to double by 2027, with AI workloads driving more than 60% of that increase, the article said.

Microsoft Corp. (MSFT:NASDAQ), Amazon.com Inc. (AMZN:NASDAQ) and Google and its parent Alphabet Inc. Class A (GOOGL:NASDAQ) are increasingly turning to long-term direct contracts, reactor restarts and small modular reactor developers as grid-connection delays and higher costs make conventional utility arrangements harder.

The U.S. grid faces an interconnection backlog exceeding 2,600 GW, with average connection waits nearing five years and project-withdrawal rates approaching 80%, the report said. The International Energy Agency estimates grid congestion puts 20% of planned data center projects worldwide at risk. In the PJM market — the largest U.S. regional transmission organization, covering the Mid-Atlantic and parts of the Midwest — delays in bringing new generation online reportedly cost consumers about US$7 billion in a single capacity auction, and each US$1 billion in postponed transmission investment could cost consumers US$150 million to US$370 million a year. Nearly half of the AI data centers planned in the U.S. for 2026 are reportedly delayed, leaving a 7 GW shortfall that threatens roughly US$650 billion in planned hyperscaler capital spending.

Large Tech Cos. Moving to Nuclear to Power Their AIs

Microsoft has moved aggressively, working with Constellation Energy Corp. (CEG:NASDAQ) to restore the former Three Mile Island Unit 1 reactor — now the Crane Clean Energy Center, according to the Informed Clearly piece. The US$1.6 billion refurbishment is expected to return the 835 MW plant to service in 2027 under a 20-year PPA covering its entire output to Microsoft.

Amazon has taken a similar tack, purchasing a Pennsylvania data-center campus directly powered by nuclear energy from the adjacent Susquehanna Steam Electric Station, while securing a long-term power arrangement tied to the facility. It is also working with Energy Northwest and X-energy Inc. (XE:NASDAQ) to develop four advanced SMRs with an initial capacity of 320 MW, expandable to 960 MW, with operations expected in the early 2030s. Amazon Web Services has said nuclear will be important to its 2040 net-zero goal while powering AI facilities that can each need 300 MW to 500 MW — roughly a mid-sized city’s consumption.

Google entered the corporate SMR market in 2025, agreeing to buy power from Kairos Power with a target of 500 MW by 2030. Rather than a single reactor, the deal uses an “order book” approach, committing Google to buy electricity from multiple SMRs as they come online — giving Kairos greater revenue visibility to help secure financing and approvals, and potentially setting a template for other tech buyers.

Meta has outlined as much as 6.6 GW of nuclear capacity through deals with Vistra Corp. (VST:NYSE), Oklo Inc. (OKLO:NYSE) and TerraPower, reflecting expectations that about a third of data centers could run independently of the traditional grid by 2030; its plan includes siting data centers next to nuclear plants with dedicated transmission links.

The shift is also reshaping power markets and climate strategies. Wholesale electricity prices around hyperscale data centers have reportedly risen 267% since 2020, while AI data centers now consume more than 500 TWh a year — more than France’s total, the report said.

“Electricity supply, not chip supply, has become AI’s binding constraint,” said Benjamin Rossi, an energy analyst at the Global Energy Institute, according to the report. “The interconnection queue crisis means that even if you have the capital and the GPUs, you cannot power them without a direct line to a baseload plant. Nuclear is the only option that scales to 500 MW per facility with 90%+ uptime.”

A Strong Year for the Element

Uranium is trading firmly, in the high-US$80s per pound in late August 2026. Spot U3O8 was quoted around US$88 on August 20, up modestly on the day and near the top of its recent range, according to market tracker CarbonCredits.com. That caps a strong year: spot jumped roughly 25% in January 2026 and briefly topped US$100 — its first time in about two years — before easing back into the high-US$80s, as buyers moved to lock up physical supply against a widely expected structural deficit, the site said. Long-term contract prices have climbed toward the mid-US$80s too, a sign utilities are contracting rather than waiting.

Turning a new uranium deposit into a producing mine typically takes well over a decade — often 10 to 15 years or more from discovery to first production, according to the World Nuclear Association. Many explorers are rushing to fill the gap, but two stand out for sharing a project generator model: acquiring a portfolio of properties, then optioning them to partners who fund exploration in exchange for an ownership stake — letting the generator test more ground while limiting its own capital outlay and dilution and keeping upside through carried interests and royalties. They are Skyharbour Resources Ltd. and CanAlaska Uranium Ltd., both applying the approach across their holdings in Saskatchewan’s Athabasca Basin.

CanAlaska Uranium Ltd.

CanAlaska Uranium Ltd. (CVV:TSX.V; CVVUF:OTCBB; DH7:FSE) is a Saskatoon-based uranium exploration company and one of the largest landholders in Saskatchewan’s Athabasca Basin, the world’s premier high-grade uranium district and source of the richest uranium deposits ever mined. [OWNERSHIP_CHART-1733]

Founded in 1985, the company holds interests in roughly 500,000 hectares (about 1.24 million acres) across the basin, along with select ground prospective for nickel, copper, gold and diamonds. Its strategic land position has long attracted major partners — it is currently working with Cameco Corp. (CCO:TSX; CCJ:NYSE) and Denison Mines Corp. (DML:TSX; DNN:NYSE.MKT) in the eastern basin. The company is led by Chief Executive Officer Cory Belyk, a former senior Cameco manager.

As part of its project generator model, rather than funding every project on its own balance sheet, it stakes and advances a large inventory of prospective ground, then brings in partners who pay to explore it — through option and joint-venture agreements — in exchange for an ownership interest. That structure lets CanAlaska keep drilling across the basin and advance discoveries while limiting the share dilution a single-asset explorer would face, preserving meaningful upside even on projects it no longer fully funds. At the same time, the company directly operates and advances its highest-priority assets, using partner capital and periodic project deals to help underwrite its own exploration.

That approach is on clearest display at CanAlaska’s flagship West McArthur project, an 89%-owned joint venture with Cameco located about 15 kilometers from the giant McArthur River mine in the eastern Athabasca Basin. Its ultra-high-grade Pike Zone discovery now spans about 500 meters of strike and remains open, with earlier drilling highlighted by an 8.6-meter interval grading 34.59% U3O8. Recent 2026 winter assays have extended the mineralized system along the C10S corridor.

Beyond the flagship, CanAlaska wholly owns the large Cree East project in the southeastern basin, which it regained fully unencumbered after terminating its option agreement with Nexus Uranium Corp. (NEXU:CSE; NEXUF:OTCQB; JA7:FRA) in September 2025, and it continues to advance a broader pipeline of uranium properties across the Athabasca Basin under its partner-funded model.

In an August 17 release, CanAlaska reported geochemical assay results from its 2026 winter drill program at the West McArthur Project in the Athabasca Basin, confirming uranium mineralization along the C10S corridor and supporting the potential for additional high-grade zones beyond the Pike Zone.

During the winter campaign, CanAlaska tested areas extending southwest and northeast of the existing high-grade Pike Zone footprint. Drilling reached 350 meters in both directions and encountered persistent alteration, structural features, graphitic host rocks and uranium mineralization associated with both the unconformity and basement. The assay results corroborate previously released radiometric equivalent uranium results and indicate that the hydrothermal system continues along the C10S corridor in both directions, suggesting additional high-grade mineralized pods could occur along the trend.

“Confirmation of uranium mineralization in geochemical assays is an important step in showing the potential for the C10S corridor to host additional zones of high-grade mineralization,” CEO Belyk said. “As the summer program progresses, the CanAlaska team is very focused on following the alteration and uranium mineralization along the host fault structure looking for the start of that next ‘pearl’ of high-grade uranium. CanAlaska remains well funded for the summer drilling program with over $25 million in the treasury.”

The winter program included 24 unconformity-targeted holes, with 10 intersecting uranium mineralization. CanAlaska said the drilling has now traced the hydrothermal system across approximately 1.3 kilometers of strike along the C10S corridor, with uranium mineralization extending across more than 1 kilometer, including the 140-meter high-grade core of the Pike Zone. Drilling also helped identify structural controls and alteration patterns associated with mineralization on multiple fences northeast and southwest of Pike, reinforcing the potential for additional mineralized pods. Assays from WMA101-02 and WMA100-02 further confirmed high-grade uranium away from the existing Pike Zone in both directions along the C10S trend.

Among the reported intersections, WMA100-02 returned 0.5 meter grading 2.89% U3O8, while WMA101-02 returned 5.4 meters averaging 1.48% U3O8, including 0.5 meter at 8.42%, 0.5 meter at 3.97% and 0.4 meter at 10.5% U3O8. Other holes also encountered uranium mineralization, including WMA101-01, which returned 0.5 meter at 0.95% U3O8, and WMA098-04, WMA100-03, WMA101, WMA101-03, WMA101-06, WMA104 and WMA105, which recorded additional mineralized intervals.

The reported intersections use drill-hole depths and do not represent true thicknesses, which have not yet been established. CanAlaska calculated certain intervals using cutoffs of 0.1% U3O8, 2.0% U3O8 or 0.1% eU3O8, depending on the reported interval, with radiometric equivalent grades derived from a calibrated downhole gamma probe.

The West McArthur Project is operated by CanAlaska under a joint venture with Cameco, with CanAlaska holding an 88.89% interest. Cameco and CanAlaska are jointly funding the 2026 exploration program.

Leede Financial Inc. flagged CanAlaska’s update in its Daily Insights note on August 17. According to Leede, the results were encouraging on both fronts. The company “successfully stepped out 350 meters southwest and 350 meters northeast from previous drilling, intersecting continued strong alteration, structure, graphitic host stratigraphy,” along with multiple drill fences carrying unconformity-associated and basement-hosted uranium mineralization. The assays confirmed the previously reported eU3O8 results and tied the mineralization to hydrothermal alteration and structural disruption along strike in both directions.

Leede noted that the continuation of the hydrothermal system and uranium mineralization on trend from the high-grade Pike Zone underscores the potential for additional high-grade pods and the need for continued systematic evaluation along the C10S corridor in both directions.

Analyst sentiment on CanAlaska skews positive. In its most recent note, dated January 19, 2026, Canaccord Genuity set a CA$1.35 price target with a Moderate Buy rating — implying about 62.65% upside from the share price on the day of the report, according to MarketBeat data. Two earlier calls also landed in bullish territory: Desjardins’ B. Adams upgraded the stock to Moderate Buy on April 3, 2025, and Cormark’s N. Dion upgraded it to Moderate Buy on January 7, 2025.

¹About 4% of the company is held by insiders and management and about 33% by institutions. The rest is retail.

Its market cap is CA$75.75 million with 220.99 million shares outstanding. It trades in a 52-week range of CA$0.32 and CA$1.26.

Skyharbour Resources Ltd.

Skyharbour Resources Ltd. (SYH:TSX.V; SYHBF:OTCQX; SC1P:FSE) is a Vancouver-based uranium explorer and prospect generator focused on Saskatchewan’s Athabasca Basin, the world’s premier high-grade uranium district. The company has assembled one of the largest exploration footprints in the basin — more than 682,000 hectares across upwards of 40 projects, following staking that pushed its portfolio past that mark in July 2026. Its co-flagship assets are the Moore Lake and Russell Lake projects in the eastern basin, which it advances directly, while a deep bench of secondary properties is farmed out to partners. The company is led by President and CEO Jordan Trimble.[OWNERSHIP_CHART-6026]

Like CanAlaska, Skyharbour runs a prospect generator model: it brings in partner companies to acquire interests in its non-core projects by funding exploration and making cash and share payments to Skyharbour over time, letting the company concentrate its own capital on its co-flagships. The approach lets Skyharbour mitigate share dilution while retaining upside through minority interests, royalties and equity stakes in its partners, and it generates steady news flow across a diversified base of projects run by numerous operators. In aggregate, Skyharbour says its signed earn-in option agreements could deliver more than CA$79 million in partner-funded exploration and over CA$52 million in cash and share payments to the company, assuming partners complete their earn-ins.

Skyharbour’s partner roster spans both major and junior operators. It holds joint ventures with industry leaders Denison (at Russell Lake) and Orano Canada Inc. (at the Preston project), alongside a slate of earn-in option partners that includes Nexus (Mann Lake), North Shore Uranium Ltd. (NSU:TSX.V) (Falcon), UraEx Resources (South Dufferin and Bolt), Future Fuels Inc. (FTUR:TSX.V) (Highway), Mustang Energy Corp. (MEC:CSE; MECPF:OTC; 92T:FRA) (914W), Purecore Metals Inc. (PURE:CSE) (Yurchison) and Terra Clean Energy Corp. (TCEC:CSE; TCEFF:OTC; C900:FSE) (South Falcon East). Beyond its co-flagships and active partner projects, Skyharbour holds a large inventory of additional properties available for option, giving it running room to keep generating deals across the basin.

On July 30, Skyharbour announced it has entered into a definitive option agreement with Purecore Metals Inc. (PURE:CSE) that could see Purecore acquire up to a 100% interest in the Yurchison uranium property in northern Saskatchewan’s Wollaston Domain. The agreement provides Skyharbour with cash, shares and exploration spending while giving Purecore exposure to a large, underexplored uranium project in the Athabasca Basin.

Yurchison consists of 22 mineral claims spanning approximately 35,029 hectares and lies about 75 kilometers south of Cameco’s Rabbit Lake operation. The property benefits from established infrastructure and hosts Wollaston Supergroup metasedimentary gneisses, including graphitic units near Archean granitic gneisses. Historical work has included airborne and ground geophysical surveys, mapping, prospecting, sampling and drilling.

“We are very pleased to sign this new Option Agreement as we continue to execute on our dual-pronged corporate strategy by unlocking value at our Athabasca Basin project portfolio through strategic partnerships and prospect generation, as well as focused mineral exploration at our core assets of Moore and Russell,” President and CEO Trimble said. “We are looking forward to working with Purecore Metals and its capable management team as they advance the Yurchison Project over the coming years with a considerable amount of exploration planned as well as cash and share payments to Skyharbour. The project is ripe for new potential discoveries and updates will be forthcoming on exploration plans at Yurchison which will complement our ongoing 2026 drill campaigns at various other projects in our portfolio.”

Historical exploration has identified uranium grades of 0.09% to 0.30% U3O8 and molybdenum values of 2,500 to 6,400 ppm. The property also has potential for uranium-thorium-rare earth element, copper, lead and zinc mineralization. Much of the earlier exploration occurred before 2000, leaving substantial areas with limited follow-up work. More recent programs included airborne electromagnetic, magnetic and radiometric surveys in 2022 and 2023.

Under the July 29 option agreement, Purecore can earn an initial 70% interest by providing CA$350,000 in cash, CA$700,000 in shares and completing CA$3.5 million in exploration expenditures over three years. Purecore can then acquire the remaining 30% through a one-time combined cash and share payment of CA$6 million, while Skyharbour will retain a royalty interest. Closing remains subject to customary conditions, including board approvals, no material adverse changes and required regulatory clearances.

Skyharbour said historical drilling largely occurred from the 1960s through the 1980s, with additional programs during the mid-1990s and 2000s. Work near historic trenches returned uranium grades of 0.09% to 0.30% U3O8 and molybdenum values of 2,500 to 6,400 ppm in outcrop and float samples.

The western portion of Yurchison has historically focused on uranium occurrences, while exploration in the east targeted sedimentary exhalative lead-zinc mineralization associated with the nearby historic George Lake deposit. The property also contains uranium, molybdenum and thorium showings that remain prospective for basement-hosted uranium, pegmatite-hosted uranium-thorium-rare earth element mineralization and sediment-hosted copper-lead-zinc deposits. Airborne VTEM, VLF-EM, magnetic and radiometric surveys completed in 2022 and 2023 provide more recent geophysical data to guide future exploration.

Haywood Capital Markets analyst Marcus Giannini initiated coverage of Skyharbour on May 28 with a “Buy” rating and a CA$1-per-share price target, describing the company as a uranium explorer targeting unconformity-style deposits in Saskatchewan’s Athabasca Basin. He identified Moore Lake and Russell Lake as the company’s two flagship projects.

“Skyharbour is a uranium exploration company we have followed for some time and has frequently been profiled in Haywood’s Exploration Quarterly Report,” the analyst wrote. “Skyharbour is focused on the discovery of unconformity-style uranium deposits in the prolific Athabasca Basin, anchored by its co-flagship Moore Lake and Russell Lake projects.”

Giannini also emphasized Skyharbour’s prospect-generator model, which allows the company to broaden its exploration portfolio through partnerships that fund much of the work near established uranium-producing districts. He highlighted the company’s agreement with Denison Mines Corp. at Russell Lake as a key development, saying the partnership adds capital, personnel and technical capabilities from an experienced uranium producer.

“With the partnership at Russell established, a proven project in Moore, and exposure to significant exploration drilling through joint venture projects, we think the timing is right for Skyharbour to take the next step in its exploration journey,” Giannini said. “We like Skyharbour for the exposure it provides in terms of blue-sky exploration upside in a proven uranium district, while maintaining a lower risk profile relative to pure play exploration peers through its prospect generator business with minimized dilution through a partnership model.”

On July 23, 2026, The Paydirt Prospector’s Jeff Clark and Daniel Flynn reviewed Skyharbour’s recent progress and prospects. Flynn said the publication assigned the company a “Hold” rating in its summer portfolio review, primarily because Moore Lake had generated relatively few updates since drilling began.

Flynn nevertheless pointed to a substantial pipeline of potential catalysts, including results from an expanded drilling program expected to be roughly twice the size of last year’s campaign. He said assay results from Moore Lake and other properties could create additional value, while noting that Clark continues to hold an overweight position in Skyharbour.

¹Skyharbour Resources Ltd. has a market cap of CA$94.48 million, with 221.15 million shares outstanding. The company’s 52-week range is CA$0.28-CA$0.66. Institutions own 29.59% of shares, while management and insiders own 3.13%. The rest are retail.

Common Investor Questions

Why is artificial intelligence driving new interest in uranium? AI data centers consume enormous amounts of around-the-clock power, and that demand is straining the grid — utilities and tech companies are turning to nuclear as a reliable, high-uptime baseload source. Data-center electricity demand is expected to double by 2027, with AI workloads driving more than 60% of that increase, which strengthens the long-term case for the uranium that fuels reactors.

How are big tech companies securing nuclear power? Through direct, long-term power-purchase agreements, reactor restarts and small modular reactor (SMR) developers. Microsoft contracted the entire output of the restarting Three Mile Island Unit 1 (now the Crane Clean Energy Center); Amazon secured capacity from Pennsylvania’s Susquehanna plant and is backing X-energy SMRs; Google is buying SMR power from Kairos; and Meta has lined up as much as 6.6 GW through deals with Vistra, Oklo and TerraPower.

What is uranium trading at right now? Spot U3O8 was quoted around US$88 per pound on August 20, 2026, in the high-US$80s range. Prices jumped roughly 25% in January 2026 and briefly topped US$100 — the first time in about two years — before easing back, as buyers moved to lock up physical supply against an expected structural deficit. Long-term contract prices have climbed toward the mid-US$80s.

Why does the Athabasca Basin matter? Saskatchewan’s Athabasca Basin is the world’s premier high-grade uranium district and the source of the richest uranium deposits ever mined. It hosts Cameco’s giant McArthur River mine and attracts major partners like Cameco, Denison and Orano, which is why explorers concentrate their ground there.

What is the “project generator” (prospect generator) model? It’s a strategy where a company assembles a large portfolio of exploration properties, then options them to partners who fund the drilling in exchange for an ownership stake. This lets the generator test more ground while limiting its own spending and share dilution, keeping upside through carried interests, royalties and equity in partners. Both featured explorers — CanAlaska and Skyharbour — run this model.

What is CanAlaska’s flagship project? West McArthur, an ~89%-owned joint venture with Cameco in the eastern Athabasca Basin, about 15 km from the McArthur River mine. Its ultra-high-grade Pike Zone discovery now spans about 500 meters of strike and remains open; drilling has returned intercepts including 8.6 meters at 34.59% U3O8 and grades locally reaching 85.4% U3O8. Recent winter assays extended the mineralized system along the C10S corridor.

What is Skyharbour’s flagship, and what did it just announce? Its co-flagship projects are Moore Lake and Russell Lake in the eastern basin. On July 30, 2026, Skyharbour signed an option agreement letting Purecore Metals earn up to 100% of the Yurchison uranium property (about 35,029 hectares, ~75 km south of Cameco’s Rabbit Lake), giving Skyharbour cash, shares and exploration funding while it focuses capital on its core assets.
