North Shore Uranium

Investor Insight

With a focused and cost-efficient exploration strategy, North Shore Uranium is building a dual-jurisdiction uranium portfolio in two of North America’s most prolific uranium districts: Saskatchewan’s Athabasca Basin and New Mexico’s Grants Uranium District.

Overview

North Shore Uranium (TSXV:NSU) is a North America-focused uranium exploration company advancing a dual-track strategy, targeting high-impact discoveries in two of the world’s most prolific uranium jurisdictions: the eastern Athabasca Basin region in Saskatchewan, Canada, and the Grants Uranium District in New Mexico, USA. With a lean capital structure, fully permitted drill targets in Saskatchewan, and strong insider ownership, the company is well-positioned to deliver value through cost-effective exploration and resource definition in a rising uranium price environment.

Rio Puerco project in New Mexico’s Grants District, is a historically productive uranium belt responsible for over 340 million pounds of past U3O8 production. Using data from approximately 800 historical drill holes a JORC-compliant inferred resource estimate of 11.4 million pounds U₃O₈ 1 was completed in 2009. Early evaluations suggest potential for in-situ recovery (ISR) mining – one of the lowest-cost extraction methods in the industry.

At Falcon in the Athabasca Basin, North Shore’s maiden 2024 drill program confirmed near-surface uranium mineralization in previously untested zones, highlighting the project’s potential for new discoveries. The company has identified a 7-kilometre conductive corridor with high-priority drill targets named the South Priority Area, and is planning prospecting and follow-up drill programs.

Rio Puerco project area

Strategically, North Shore stands out among junior explorers by offering exposure to two of the most politically stable and uranium-endowed regions in the world.

With macro tailwinds, including spot uranium prices surpassing US$100/lb in 2024 and recent US policies aiming to triple nuclear energy capacity by 2050, the company is positioned to benefit from growing demand and supportive permitting regimes in both Canada and the United States.

Key Projects

Rio Puerco Uranium Project

On June 23, 2025, North Shore signed a binding term sheet with Resurrection Mining LLC for a transaction that would allow North Shore to acquire up to an 87.5 percent interest in Rio Puerco. Closing of the transaction by August 31, 2025 is subject to final due diligence, execution of a definitive agreement, completion of a minimum $750,000 financing by North Shore and approval by the TSX Venture Exchange. Rio Puerco is located 60 km northwest of Albuquerque in the prolific Grants Uranium District. The Grants District has historically produced over 340 million lbs of U₃O₈, making it the most productive uranium region in the United States. Rio Puerco consists of 37 Bureau of Land Management claims and benefits from existing access infrastructure.

Rio Puerco is surrounded by advanced uranium exploration/development projects.

The Rio Puerco deposit is hosted in the Westwater Canyon Member of the Jurassic Morrison Formation – a well-known host for peneconcordant sandstone-hosted uranium mineralization. Kerr-McGee drilled over 1,000 holes on the property and surrounding area in the 1970s and initiated development of a room-and-pillar underground mine. Mining operations were suspended in 1980 due to collapsing uranium prices. A 2009 resource estimate by Monaro Mining outlined a JORC-compliant historical inferred resource of 6 million tonnes grading 0.09 percent eU₃O₈ for 11.4 million lbs of contained U₃O₈.1 This estimate was validated by a 2011 technical report commissioned by Australian-American Mining Corporation.

The deposit is believed to have potential for ISR mining – a low-cost, environmentally friendlier method used in many US uranium projects. After completion of the Rio Puerco transaction, North Shore’s near-term plan is to validate historical data through a 20- to 40-hole drill program, including both rotary and diamond core holes, and evaluate the ISR potential through hydrogeological, geochemical and metallurgical testing.

Rio Puerco represents a near-term opportunity to define a modern resource in a supportive permitting and policy environment. Recent executive orders by the US government aim to accelerate nuclear permitting timelines. The project lies entirely on BLM land and is situated near advanced-stage uranium projects such as Marquez-Juan Tafoya (Anfield Energy) and Cebolleta (Premier American Uranium), enhancing the district-scale relevance of the asset.

Falcon Property

Falcon is located along the Wollaston Domain at the eastern margin of Saskatchewan’s Athabasca Basin, the property spans 55,503 hectares across 15 mineral claims. North Shore owns 100 percent of four claims totalling 12,800 hectares and holds an option to earn up to a 100 percent interest in the remaining 11 claims from Skyharbour Resources by October 2027. The project benefits from excellent infrastructure, including proximity to the active Key Lake uranium mill (30 km west) and a powerline traversing the property’s eastern boundary.

The Falcon area has similarities to the base of the nearby Key Lake deposit, where uranium is associated with fault zones just below the unconformity between overlying sandstone and basement rocks. At Falcon, the sandstone cover has been eroded, exposing basement rocks, making it an ideal target for basement-hosted mineralization. Historical work from the 1960s to early 2000s identified numerous uranium occurrences at Falcon, including “radioactive boulders”, uranium showings as well as strong EM conductors. High-resolution airborne geophysical surveys were flown in 2006, 2007, 2013 and 2022. These datasets, combined with new and historical drill results, and new geophysical modeling, have allowed North Shore to define and prioritize 36 exploration targets, including 11 high-priority targets across three priority zones.

In March 2024, North Shore completed its maiden drill program at Falcon, targeting three previously undrilled EM conductor anomalies (P03, P08, P12). At P08 and PO3 , drilling intersected three near-surface, uranium-bearing fault zones. The most notable interval at PO8 at a depth of 45 metres returned 4.7 metres at 316 parts per million (ppm) U₃O₈, with a one sample returning 572 ppm U₃O₈1. These zones are associated with brittle faulting, strong bleaching, hematite and chlorite alteration, and clay-rich shearing – classic indicators of uranium-bearing structures in the Athabasca context.

Target FA025, near mapped location of the D Zone showing

Current exploration at Falcon is primarily focused on the South Priority Area, a 7 km EM conductor trend that includes the P03 and P08 discoveries and high-priority targets such as FA002, FA003, F004 and F005. In target zone 3, FA025 hosts the historical D Zone showing (1.26 percent uranium and 0.8 percent molybdenum in a mineralized vein). Only three shallow holes totaling 350 m have been drilled at FA025. The project is fully permitted for drilling and North Shore inked an exploration agreement with the English River First Nation in March 2025.

West Bear Property

Located approximately 90 km north of the Falcon property, the West Bear Property comprises five claims totaling 4,511 hectares and is located at the eastern edge of the Athabasca Basin. It is adjacent to a known uranium and cobalt-nickel resources held by Uranium Energy Corp., including a Co-Ni resource of 3.8 million lbs of cobalt and 3.2 million lbs of nickel, as well as a probable uranium reserve of 1.4 million lbs U₃O₈. The proximity to these advanced-stage assets provides geological validation of the regional prospectivity.
