Greenridge Exploration Inc. Completes Extensive Exploration Program on its Nut Lake Project in the Thelon Basin, Nunavut
Greenridge Exploration Inc. announced it has completed its extensive summer exploration program on its Nut Lake Project (the ‘Nut Lake Project’ 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. 2024 Work Program On behalf of Greenridge, Dahrouge Geological Consulting Ltd. (‘DGC’ or ‘Dahrouge’) conducted an eighteen-day, large-scale exploration program (the ‘Program’) on the Company’s Nut Lake Project which included: Detailed geological mapping in previously identified, high-grade showings; Prospecting and rock sampling over priority target areas; and Scintillometer sweeps over priority areas that were lacking outcrop. The primary goal of the Program was to follow-up on historical exploration, delineate the nature of these showings and in the process, highlight high-priority areas that may be further investigated in a future drill program. DGC has applied its established targeting methodology to Greenridge’s geological data, incorporating historical and recent exploration records to highlight high-priority areas. The 2024 summer exploration Program focused on the Tundra Showing, the Heartbreak Showing, the Lakeshore Showing, the 431 Dike Swarm Showing and the 448 Anomaly Showing, highly prospective areas within the Project that have historically yielded high-grade mineralization. Other priority items for the Program included investigation of numerous uranium anomalies found in the SE region of the Project. Greenridge has confirmed promoted radioactivity across all known zones. Multiple historical trenches and drill collars were identified during the Program. Notably, a new zone, the Tayson Zone, was discovered, revealing a mineralized vein approximately 2 meters long by 2 cm. The Tayson Zone returned off-scale readings on an RS-125 Super-Spectrometer. This spectrometer, which is capable of differentiating uranium (U), potassium (K), and thorium (Th), recorded multiple highlight zones with off-scale readings, signaling potential significant mineralization. A total of 182 samples were collected, including 149 in situ from outcrop or subcrop and 33 float or boulder samples. Out of these samples, 62 samples exhibited anomalous radioactivity at >1000 counts per second (‘cps’), and 22 were measured above 5000 cps. Seventeen (17) sample locations showed readings greater than 30,000 cps, with six sample locations registering off-scale radioactivity. It is important to note that while promoted radioactivity is promising, it does not directly indicate uranium mineralization, and further assays are required to confirm the presence of uranium or other economically valuable minerals. This data provides a strong foundation for follow-up exploration work to assess the full potential of the mineralization in these zones. The Project is located approximately 55km north of the Angilak Uranium Deposit 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 promoted 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. 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 6920ft of diamond drilling completed on it. Multiple holes intersected significant uranium mineralization, with the most noteworthy being at the Tundra Showing Hole Winkie AX W-24 intersected 9ft of 0.69% U3O8 including 4.90% U3O8 over 1ft from 8ft depth. 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. 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 Project has the potential to host unconformity vein and breccia type, syngenetic and sandstone-hosted phosphatic type mineralization.
