Greenridge Exploration Provides Updated Technical Review of its Nut Lake Uranium Project in the Thelon Basin, Nunavut

VANCOUVER, Aug. 15, 2024 - Greenridge Exploration Inc. ("Greenridge" or the "Company") (CSE: GXP | FRA: HW3), is pleased to announce it has completed an updated technical review of the Nut Lake Uranium Project (the "Nut Lake Property" or the "Project") located in the Thelon Basin in Nunavut. The Project covers approximately 5,853 hectares near the Northern Tip of the Yathkyed Basin, a sub-basin of the Thelon Basin (please see Figure 1).

Technical Review Update

Dahrouge Geological Consulting Ltd. ("DGC"), on behalf of the Company, completed a secondary assessment of the historical data compiled for the Nut Lake Property, building on the previous technical review detailed in the Company's news release dated April 4, 2024. The second pass performed by DGC was focused on compiling and investigating historical data for the Project, including digitizing drillhole information, georeferencing maps, and pulling data from historical reports on or near the Nut Lake Property. The highlights of this secondary assessment are listed below:

About The Nut Lake Property

The Project is located approximately 55km north of the Angilak Uranium Deposit⁵ or 180Km southwest of Baker Lake, Nunavut in the Yathkyed Basin (a sub-basin of the prolific Thelon Basin) in Nunavut Territory, Canada. The Project consists of three contiguous mineral licences encompassing a total land area of approximately 4,036 hectares (~40km²).

In 1979, Pan Ocean Oil Ltd. performed an exploration program consisting of ground geophysics, geological mapping, prospecting and Winkie drilling as follow up to previous sampling with elevated uranium in dyke swarms, fractures and contacts between syenites and trachytes. The geology of the Project area consists of basal sedimentary rocks of the South Channel Formation, composed of white quartzites and pink to grey arkose and arkosic rocks. The sedimentary sequences of the lower Dubawnt Group are unconformably or disconformably overlain by volcanic rocks of the Christopher Island Formation.

The Project hosts high grade vein hosted grab samples of up to 4.36% U3O8, 53.16 oz/t Ag, 1.15% Pb and 7.0% Ni.¹

During the 1979 field season, geological mapping at a scale of 1:1,000 was completed on a major portion of the Project. This was concurrent with prospecting on, and in the immediate area of the Project. Results from prospecting were the discovery of two (41 m wide) syenite dikes and a frost heaved area of felsic gneiss with up to 3,000 cps on fracture surfaces. Two significant Uranium bearing showings were discovered, the "Lake Showing" and the "Heartbreak Showing". The most noteworthy was the Heartbreak showing which revealed 3.0" and 3.5" samples across a fracture that assayed 2.11% U3O8 and 4.36% U3O8 respectively. The results were followed up with a radon gal survey, a VLF-EM survey and an overburden sampling program. The radon survey results showed that the response is irregular with several good highs and the VLF-EM survey showed a series of northwesterly trending anomalies. It was concluded that further drilling of the Lake Showing is recommended.

The Project and surrounding proximal area have seen approximately 805ft of Winkie Drilling and 6,920ft of diamond drilling completed on it. Multiple holes intersected significant uranium mineralization, with the most noteworthy being at the "Tundra Showing" where Hole Winkie AX W-24 intersected 9ft of 0.69% U3O8 including 4.90% U3O8 over 1ft from 8ft depth.¹ Additional noteworthy holes were hole P049 which returned approximately 0.20% U3O8 over a one-foot interval and hole 068 which was drilled to intersect fracture mineralization and successfully encountered approximately 0.59% over 1 foot (Pan Ocean Oil Ltd., 1979 Assessment Report #81075).

The combination of historically defined anomalies and modern exploration techniques provides prime ingredients for the potential of discovering a high-grade uranium system within the Project area. The Nut Lake Property has the potential to host unconformity vein and breccia type, sygenentic and sandstone-hosted phosphatic type mineralization.
