Golden Pursuit Resources Announces Completion of the 2025 Exploration Program at Gordon Lake Project, NWT

18.09.2025  |  Newsfile

Vancouver, September 18, 2025 - Golden Pursuit Resources Ltd. (TSXV: GDP) is pleased to announce the completion of work on its 2025 exploration program at its Myrt Lake property located in the high-grade Gordon Lake gold mining district of Canada's Northwest Territories.

This news release announces the results submitted with the 2025 Myrt Lake Assessment Report, which fulfill the mandatory requirements for maintaining our Myrt Lake federal claim and extending the claims until 2033.

The historical mineral resource estimate reported for the Myrt Lake property is considered relevant; however, it was prepared prior to the implementation of current Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards and without the application of modern quality assurance/quality control (QA/QC) protocols. The Company has not completed sufficient work to verify the historical data underlying the estimate, and the estimate should not be relied upon as a current mineral resource. In order to upgrade and verify the historical estimate, the Company anticipates that a program of data validation and confirmatory exploration will be required, including the compilation and review of historical drill hole data, verification of collar locations and surveys, re-logging and re-sampling of available core, implementation of a modern QA/QC program, and the completion of confirmatory drilling. Additional metallurgical test work may also be necessary to demonstrate reasonable prospects for eventual economic extraction. A new mineral resource estimate prepared in accordance with NI 43-101 and CIM standards would be required before the historical estimate can be considered current.

Highlights

• New high-grade results indicate a new mineralized zone: Gold assay results from samples D6-2 (25.2 g/t Au) and D10 (22.7 g/t Au) indicate the discovery of a new mineralized zone. This discovered area lies approximately 2 km west of the historic mine workings, with the samples aligning in a NW/SE orientation and taken from gossanous outcropping rocks approximately 900 meters apart. Further work, including geophysics and drilling, is planned.

• Additional high-grade confirmation includes a 41.7 g/t (ML-10) sample collected from a well-mineralized quartz vein over 20 meters of width and at least 100 meters of length. The mineralized vein is hosted within siltstone near former mine workings, and contains significant galena, black sphalerite, silver and pyrrhotite in addition to gold. It exhibits a distinctive blebby texture-where small, rounded blebs or inclusions of these minerals are distributed throughout the vein material.

2025 Myrt Lake Exploration Program

• Litho-Structural Mapping and Sampling: Detailed litho-structural mapping and additional rock sampling were carried out at the Myrt Lake property. Detailed geological mapping data, structural measurements and rock sampling were conducted to identify new exploration targets and to increase the extent of near-surface high-grade mineralization surrounding known workings and mineralization showings (Figure 1).

• Assay and Multi-Element Geochemical Analyses: Rock samples were submitted to the ALS laboratory in Yellowknife for assay and geochemical analyses (Figure 2). Additional sampling results from other claim groups owned by the company are expected by the end of September.

The Myrt Lake claims have been subject to several drilling campaigns and underground development work. In 1974, exploration initiated with an underground development program including a decline of 466 feet, and 405 feet of drifting and crosscutting along the #1 vein. In 1977, additional 3,650 feet of underground drilling were completed in 15 drillholes. A total of 3,000 tons of ore grading 0.11oz/t was mined and stockpiled (Clarke, 1985). Ore reserves were estimated to be 25,275 tons grading 0.22 oz/t Au down to 125 feet. In 1984, Ryan Energy completed 5,585 feet (1,702 m) of drilling across 10 drillholes, verifying the continuity of Zones No. 1 and No. 3 to the northwest at depths exceeding 500 feet (152 m). In 1989, the decline was rehabilitated, and 2,152 tonnes of the stockpile material were sent to the Giant Mine for processing in 1992. From this material, 730 ounces of gold grading 0.36 oz/t at a recovery rate of 86% were produced. Knutsen (1987) calculated a minable resource to a depth of 110' of 17,510 tons grading 0.35 oz Au/ton, containing 6,132 oz Au. No work has been carried out since the completion of this bulk sampling. *Reported resources presented here are historical, non-compliant with NI-43 guidelines, and are not being used as current (Knutsen, 1987).

The 2025 exploration program on the Myrt Lake Project was designed to build on historical high-grade results and mine operations, where sampling and drilling intersected significant gold mineralization. Detailed litho-structural mapping and rock sampling helped to better understand the structural-geochemical relationships associated with gold mineralization. Recent targeted exploration efforts have focused on delineating targets, refining the geological model, and planning drillholes.

The new results reported below (Table 1) reinforce the high-grade potential of the Gordon Lake gold mining district. These results highlight the mineralization potential at the Myrt Lake area and confirm the presence of very high-grade gold content near historic workings. Ten samples out of a total of twenty-four showed gold grade results above a 0.2 g/t cutoff.

About the Gordon Lake Project

The Gordon Lake Project, about 80-90 km northeast of Yellowknife, NWT, covers 6,850 hectares and includes 18 territorial claims, 13 federal claims, and five historic mining leases-all fully owned by Golden Pursuit. The site features multiple gold showings with a history of exploration and mining dating back to 1937 and continuing into the late 1980s. Located in the Slave Structural Province of the Canadian Shield's Archean granite-greenstone craton, the property hosts gold-bearing quartz veins and breccia zones primarily in Burwash Formation metaturbidite rocks of the Yellowknife Supergroup.
