Argyle Resources completes 2026 field program at McKay Hill

Calgary, Alberta--(Newsfile Corp. - September 17, 2026) - Argyle Resources Corp. (CSE: ARGL) (OTCQB: ARLYF) (FSE: ME0) ("Argyle" or the "Company") is pleased to announce the successful completion of the 2026 exploration program on the McKay Hill Silver Gold property located about 50 kilometers north of Keno City, Yukon Territory.

After compiling historical data on the McKay Hill Silver Gold property, fieldwork consisted of prospecting, mapping, and detailed mapping in high-priority areas, as evidenced by limited rock exposures. A total of 678 soil samples were collected on a grid oriented on northing and easting to expand the known areas of mineralization. A VLF electromagnetic magnetometer was also utilized to delineate exposed veins and to extend further known veins.

A total of 45 rock samples were taken, in which the previously known zones were sampled, and newly discovered zones were also sampled. Soil geochemistry was used to potentially trace extensions to all zones identified, including newly discovered zones in the 2026 work program.

Early in 2027, a lidar survey will be conducted over the whole property to potentially display areas of structure through orthophoto interpretation, allowing for targeted prospecting, which will start off the 2027 work season.

As compilation of the 2026 field season data is ongoing, Argyle Resources will release new information as it receives it from the geologists.
