ARGYLE RESOURCES REPORTS INITIAL RESULTS FROM 2026 EXPLORATION PROGRAM AT MCKAY HILL SILVER-GOLD PROPERTY, YUKON

Argyle Resources Corp. has released initial results from its 2026 exploration program conducted on the historic McKay Hill silver gold property located approximately 90 kilometres north of Mayo, Yukon Territory.

The McKay Hill property consists of 212 contiguous claims. Work on the McKay Hill property was concentrated on previously identified zones of mineralization and historical workings. To date, mineralization is vein-type intermediate sulphidation, coupled with stratiform replacement mineralization.

Two thousand twenty-six work consisted of soil sampling, VLF geophysics, prospecting and property mapping. Building on previous and historical work, the 2026 exploration program focused on prioritizing areas of known zones, further detailing these zones to develop for drilling, while expanding beyond known boundaries of mineralization.

2026 exploration program highlights

Highlights of the 2026 work program are the discovery of 12 new veins and vein systems. The 2026 work program identified a 1.5-metre-wide quartz vein with trace galena in the valley on the west side of the White Hill zone. This vein lies nearly 2.7 kilometres west of the central zone, indicating that the regime controlling the Pb (lead) mineralization extends further west than previously known.

Possible western extension of the Nash vein in the Independence North zone was identified by a 0.75-metre-to-two-metre vein outcropping in strongly altered orange basaltic conglomerate. Mineralization identified was trace galena but displayed promising textures (boiling, prismatic and banded) akin to the Nash vein, which is located 115 m to the east (which assayed approximately 15 per cent Pb and approximately 4.5 per cent Zn (zinc)).

Identification of a greater than two m well-mineralized quartz vein on the south slopes of the main zone, below the tree line, likely represents an extension of the Blackhawk West vein system. This vein hosted up to 60-per-cent massive Galena and freibergite locally.

The above mineralized zone map shows the zones discovered to date. It has become apparent that, due to the large size of the property, a technique to focus exploration in new areas is required. A drone lidar (light detection and ranging) survey is planned as the initial work phase for the 2027 program, followed by mapping, prospecting and soil sampling. The 2027 season will also include diamond drilling to test the Pb/Ag/Au mineralization identified to date.
