Greenridge Exploration Engages Airborne Electromagnetic Survey for the McKenzie Lake Uranium Project in Northern Saskatchewan
VANCOUVER, British Columbia, June 19, 2025 (GLOBE NEWSWIRE) -- Greenridge Exploration Inc. (“Greenridge” or the “Company”) (CSE: GXP | FRA: HW3 | OTCQB: GXPLF), is pleased to announce it has contracted Axiom Exploration Group Ltd. of Saskatoon, Saskatchewan, Canada (“Axiom”) to perform a helicopter-borne time-domain electromagnetic (“HTDEM”) survey on the McKenzie Lake Uranium Project (“McKenzie Lake”, or the “Project”). McKenzie Lake consists of five (5) mineral claims comprising a total area of 6,916 hectares (17,089 acres) located near the eastern margin of the Athabasca Basin approximately fifty-five (55) kilometres southeast of the McArthur River Uranium Mine. The high-resolution HTDEM survey is designed to delineate conductive structural corridors unknown to previous uranium explorers that could be prospective for hosting uranium mineralization.
Russell Starr, Chief Executive Officer of the Company stated, “We are pleased to launch a HTDEM survey at the McKenzie Lake Uranium Project, aimed at advancing our understanding of its mineralization potential and to continue enhancing historical data on the Project. The Company is proud to be partnering with Axiom through its proprietary Xcite™ HTDEM system, which has a proven ability to detect conductive zones up to hundreds of meters of depth. The results will be integrated with our 2021 survey data to guide further exploration.”
Highlights of the Upcoming McKenzie Lake Airborne Survey
- Axiom, in partnership with New Resolution Geophysics, will utilize its proprietary Xcite™ HTDEM system, which has proven its ability to detect conductive zones up to hundreds of metres deep (Please see Figure 1). Uranium deposits in the Athabasca Basin region are often found in association with conductive rocks composed of graphitic horizons and sulphide mineralization, which can be readily detected by a sophisticated airborne survey such as the Xcite™ system.

- The airborne work is planned to consist of 403 line-kilometres at 200 metre line spacing to provide the first deep-penetrating electromagnetic survey of the Project area in the modern era of uranium exploration.
About McKenzie Lake
McKenzie Lake is located outside of the eastern margin of the Athabasca Basin within the Wollaston Domain basement rocks, which host prolific uranium mines such as Key Lake, McArthur River, Cigar Lake and Rabbit Lake, amongst others. Recent uranium discoveries of note have been made in the McKenzie Lake area, southwest of the McKenzie Lake claims. The first is a discovery at the Gemini Project, owned by Atha Energy Corp., where strongly anomalous basement-hosted uranium mineralization was first intersected in drill hole GEM-004 in 2021. The second discovery, also made in 2021 and located in close proximity to the Gemini Project, was where Baseload Energy Corp. reported the intersection of a broad zone of anomalous radioactivity in drill holes, which led to the delineation of the Ackio Zone in subsequent drilling programs (Please see Figure 2).

McKenzie Lake 2023 Prospecting Program
In October 2023, ALX Resources Corp. (a mineral exploration company acquired by Greenridge in December 2024) reported the results of a helicopter-supported prospecting program at McKenzie Lake that was designed to follow-up on radioactive anomalies detected in a 2021 airborne magnetic and radiometric survey.3 Due to inclement weather conditions that affected flight operations, the amount of field work was limited. Boulders or outcrops of interest were sampled and measured for radioactivity with a hand-held RS-125 Super-SPEC gamma-ray spectrometer, which displays radioactivity in counts per second (“cps”) (Please see Figure 3).
Figure 3. Radioactive boulder discovered at McKenzie Lake in October 2023 (16,000 cps; RS-125)
A large, angular radioactive boulder was excavated in the 2023 program that assayed 0.101% U3O8 (Please see Figure 4). Boulder #1, from which a sample was first collected in 2021, is interpreted from the geochemical assay results to be derived from a calcareous arkose or calc-silicate rock that forms part of the Wollaston Domain metasediments. The 2023 prospecting program revisited this boulder sample and excavated the overburden cover to gain a better understanding of the nature of this occurrence. The excavation showed that it was a much larger boulder than originally discerned from the 2021 prospecting program - the boulder is approximately 0.4 by 0.6 metres in top surface area and least 30 centimetres thick.

Detailed examination of Boulder #1 also revealed that the uranium mineralization is associated with hydrothermal hematite alteration. Furthermore, it was observed that the boulder is very angular, which indicates that it has likely not been transported very far from the original bedrock source via glaciation. Greenridge believes that further discoveries of radioactive boulders of this type could eventually lead to a uranium-mineralized source.
Greenridge’s 2025 Exploration Goals at McKenzie Lake
Greenridge plans to integrate the results of the 2025 HTDEM survey with the outcomes of the 2021 high-resolution magnetic and radiometric survey to focus on detailed prospecting at the Project. The discovery by Greenridge of additional radioactive boulders and other radioactive anomalies in surficial soils and sediments could lead to an “up-ice” source for uranium mineralization, as was demonstrated by the recent Gemini Project discovery. The Company holds an exploration permit for airborne and ground geophysics and surface prospecting and sampling, valid to March 31, 2027.
