Terra Clean Energy (CSE:TCEC,OTCQB:TCEFF,FSE:C9O0) is advancing its 100 percent-owned South Falcon East Project, strategically located in the southeastern Athabasca Basin, Saskatchewan — one of the world’s premier uranium districts. The project stands out among uranium juniors for its shallow mineralization, strong discovery potential, and proximity to established infrastructure.
Anchored by a historical resource of nearly 7 million pounds (Mlbs) U₃O₈ at the Fraser Lakes Zone B, the project also hosts multiple zones of confirmed mineralization and structural alteration. Terra is advancing toward a NI 43-101-compliant resource update in 2025, with the goal of materially expanding its resource base. Situated along the highly prospective Way Lake Conductor — a folded, uranium-enriched corridor — the project offers significant upside for new discoveries beyond the existing resource.
South Falcon East, Terra Clean Energy’s flagship project, spans 12,234 hectares on the southeastern margin of the Athabasca Basin, Saskatchewan, just 55 km east of the historic Key Lake uranium mill. The project hosts the Fraser Lakes Zone B deposit, with a historical inferred resource of 6.96 Mlbs U₃O₈ at 0.03% and 5.34 Mlbs ThO₂ at 0.023 percent, contained within 10.35 Mt using a 0.01 percent U₃O₈ cutoff. While not yet classified under NI 43-101, Terra considers the resource data reliable and a strong foundation for future exploration and growth.

With a clear, discovery-focused strategy, Terra Clean Energy is advancing one of the most unique near-surface uranium opportunities in the Athabasca Basin, targeting rapid resource growth and re-rating potential through continuous exploration, aggressive drilling, and disciplined capital deployment.
With a historical uranium resource of nearly 7 million lbs (Mlbs) U₃O₈ at Fraser Lakes Zone B, and multiple zones of confirmed mineralization and structural alteration, Terra is targeting an updated NI 43-101 resource in 2025, aiming to significantly grow its asset base. The project’s location along the Way Lake Conductor – a folded, fertile corridor – offers blue-sky potential for additional discoveries.
As global demand for uranium surges due to energy security concerns and the electrification boom (AI, EVs, nuclear baseload), Terra offers investors a rare combination of historical resource foundation, shallow mineralization, and transformational growth potential at a micro-cap valuation.
Located in the southeastern margin of the Athabasca Basin, Saskatchewan, South Falcon East is Terra Clean Energy’s flagship project, covering approximately 12,234 hectares of prospective uranium ground. The property lies 55 km east of the historic Key Lake uranium mill and hosts the Fraser Lakes B deposit, which hosts an inferred historical resource of 6.96 Mlb U₃O₈ at 0.03 percent and 5.34 Mlb thorium dioxide (ThO₂) at 0.023 percent, within 10.35 Mt of material using a 0.01 percent U₃O₈ cutoff grade. While this resource is not currently classified under NI 43-101, Terra believes the data is reliable and serves as a robust foundation for continued exploration.
The mineralization is hosted in fractured and altered pegmatites and graphitic pelitic paragneiss, with the uranium accompanied by thorium and elevated concentrations of copper, nickel, vanadium, zinc, bismuth, molybdenum, lead and cobalt. Alteration assemblages include illite, dickite, kaolinite, chlorite, fluorite and hematite; these are classic markers of basement-hosted unconformity uranium systems. This setting, along with widespread clay alteration and structural disruption, mirrors some of the most prolific uranium systems in the basin, including Eagle Point, Millennium and Roughrider.
Fraser Lakes B sits on the central limb of the Way Lake Conductor, a folded EM corridor extending more than 25 km across the project area. This conductor hosts three major fold limbs (West, Central, and East), but only the central limb, where Fraser Lakes B is located, has been materially drilled. The deposit currently exhibits a strike length of approximately 1,400 meters, dipping northwest, and remains open in all directions. A north-northeast-trending fault, known as the T-Bone Lineament, intersects the deposit’s eastern margin, suggesting additional structural complexity and potential uranium conduits along strike.
Historic drilling from 2008 to 2015 by Skyharbour Resources and JNR Resources identified numerous mineralized intervals. Highlights include:
These results demonstrate multiple stacked mineralized horizons over widths up to 65 m, open to depth and laterally.
In early 2024, Terra’s Phase 1 drill program confirmed the presence of uranium-bearing pegmatites in close proximity to historical intercepts. Hole SF-0059 intersected 13.5 m of mineralization, including 0.07 percent eU₃O₈ over 1.1 m, while SF-0060 returned intervals such as 0.02 percent eU₃O₈ over 1.3 m at 142.15 m. These intercepts confirm the extension of mineralization along strike and at depth from FP-15-05 and support the hypothesis of lateral continuity and stacked mineralized bodies.
Planning for an extensive summer 2025 drill program is underway, which consists of approximately 2,500 meters. The program will test areas identified during the winter 2024 program, where it is interpreted that a north-northwest trending brittle structure, a north dipping structure with strong clay alteration, and mineralized pegmatites with hydrothermal hematite alteration hosted in graphitic pelitic gneiss all intersect.
In addition to Fraser Lakes B, the company is evaluating regional targets such as T-Bone Lake, which has returned values up to 0.055 percent U₃O₈ over 0.9 m and features promising clay alteration and structural complexity similar to known high-grade deposits.
The overarching exploration thesis is that the Way Lake Conductor may host a clustered uranium system, with multiple deposits along its folded structure. Very little drilling has been conducted outside the current Fraser Lakes B footprint, giving Terra significant discovery potential across the entire 25 km strike length.

North Shore Uranium Ltd. (TSXV:NSU)("North Shore" or the "Company") is pleased to announce that on June 23, 2025, it signed a binding term sheet (the "Term Sheet") with Resurrection Mining LLC ("Resurrection"), an arm's length party, to acquire up to 87.5% of the Rio Puerco uranium project ("Rio Puerco" or the "Project") in northwestern New Mexico (the "Transaction").
TRANSACTION AND PROJECT HIGHLIGHTS
Brooke Clements, President and CEO of North Shore stated: "The Rio Puerco project in New Mexico offers us exposure to a uranium project in the USA with excellent upside and signficant historical exploration data including a historical resource estimate. The US government has recently enacted policies designed to accelerate nuclear power and uranium mining activity in the country. In the 1970s, Kerr-McGee commenced mine construction at Rio Puerco, but activity was halted after a short trial-mining phase due to low uranium prices. The Project offers a great opportunity to confirm and expand upon previous work through drilling, modern 3-D modelling and continued assessment of the ISR potential. On completion of the Transaction with Resurrection, we will have uranium exposure in two North American jurisdictions that have seen signficant uranium production, the Grants Uranium District and the Athabasca Basin, at a time when future supply-demand fundamentals look great for the industry."
Rio Puerco is located at the eastern end of the Grants Uranium District, approximately 60 kilometres northwest of Albuquerque, New Mexico (Figure 1). Mines that operated between 1950 and 2002 contributed to make the Grants Uranium District the leading historical uranium producing district in the United States.

RIO PUERCO PROJECT SUMMARY
Rio Puerco consists of 37 Bureau of Land Management mining claims and significant historic exploration and mining data as well as the rights to a water well. Historical exploration and development work by Kerr-McGee Corporation ( "Kerr McGee" ) in the 1960s and 1970s, and geologic and resource modelling work completed by two Australian companies in 2009 and 2011 validate the potential for Rio Puerco to host a significant uranium resource.
Uranium was first discovered at Rio Puerco in 1968. The claims covering the discovery were ultimately optioned to Kerr-McGee who drilled over 1,000 holes. Based on the results of that work, they began the development of the Rio Puerco Mine in the 1970s. The uranium mineralization is hosted in sandstone of the Jurassic-aged Morrison Formation, host to almost all of the significant uranium deposits in the Grants Uranium District. The mine was intended to be a room and pillar underground mine but was never put into production. Activity ceased after a short trial mining phase likely due to low uranium prices at the time. The underground mine infrastructure included a 260m vertical shaft, ventilation shafts, mining adits and support buildings. The mining shaft remains at the site and road access to the site is excellent.
In 2009, Monaro Mining NL ( "Monaro" ) commissioned an independent geological review and resource estimate for Rio Puerco using exploration data generated by Kerr-McGee in the 1960s and 1970s. The data used for the resource estimate consisted of historical maps and data from 764 drill holes including downhole gamma-ray data converted to percent equivalent U 3 O 8 (e U 3 O 8 ), geological logs and drillhole survey data. They reported a JORC 2004-compliant inferred resource of 6.0 million tonnes at an average grade of 0.09% eU 3 O 8 using a cutoff grade of 0.03% eU 3 O 8 for 11.4 million lbs. of contained U 3 O 8 1 (the " Historic Resource" ). JORC is the Australian Joint Ore Reserves Committee, a professional code of practice that sets minimum standards for public reporting of Mineral Resources.
In 2011, Australian-American Mining Corporation Ltd. commissioned a technical report on Rio Puerco. This most recent report validated and confirmed the Historic Resource 2 .
No significant exploration or development work has occurred at Rio Puerco since the 1970s.
HISTORICAL RESOURCE ESTIMATES FOR THE RIO PUERCO PROJECT
The historical resource outlined in this news release has not been verified and should not be relied upon. It is a historical estimate and not current and does not comply with Canadian NI 43-101 guidelines for the reporting of Mineral Resources. A qualified person has not verified the historical resource on behalf of the Company and North Shore has completed no work programs at Rio Puerco. Though not current, the Company views the historical resource estimates as reliable and sufficient to justify the initiation of work programs aimed at validating and potentially expanding upon the estimates. There is no guarantee that the work programs envisioned by North Shore will ultimately result in the definition of NI 43-101 compliant resources.
RIO PUERCO TERM SHEET
Completion of the Transaction is contingent on North Shore completing satisfactory due diligence, execution of a definitive agreement, completion of a minimum $750,000 financing by North Shore and approval by the TSX Venture Exchange (the "Exchange" ). A finder's fee may be payable to an arms-length third party upon completion of the Transaction. The following highlights key terms of the Term Sheet executed by North Shore and Resurrection, all currency references are in Canadian dollars:
NEXT STEPS
After completion of the Transaction, North Shore will begin working towards defining the first NI 43-101-compliant uranium resource at Rio Puerco. The Company's initial work will aim to verify historical data and determine whether a resource can be defined in accordance with NI 43-101. First, geologic models of the previously defined deposit will be prepared using drill hole summary logs containing the interpreted zones of uranium mineralization. A number of confirmation drill holes are required to confirm the historic uranium grade and uranium disequilibrium, and for metallurgical testing. For the first program, 20 to 40 holes are contemplated, a combination of diamond core holes and rotary holes where a downhole gamma ray probe is used to determine uranium content. After the results of that program are received and interpreted, a comprehensive drilling plan would be developed aimed at defining a resource. Data from the drill programs will be used to further evaluate the amenability of ISR mining.
ABOUT NORTH SHORE
The nuclear power industry is in growth mode as more nuclear power will be required to meet the world's ambitious CO 2 emission-reduction goals and the needs of new power-intensive technologies like AI. In this environment, new discoveries of economic uranium deposits will be very valuable, especially in established uranium-producing jurisdictions like Saskatchewan and New Mexico. North Shore is well-positioned to become a major force in exploration for economic uranium deposits. The Company is working to achieve this goal by exploring its Falcon and West Bear properties at the eastern margin of the Athabasca Basin in Saskatchewan, expanding its exploration efforts to include the Grants Uranium District in New Mexico and by evaluating other quality opportunities in the United States and Canada to complement its portfolio of uranium properties. North Shore summarized its exploration efforts at its Falcon property in a May 27, 2025 , news release.
