Dynasty Gold Discovers up to 50% Pyrite in South Pelham and Commences 5,000-Meter Drilling at Thundercloud in Ontario

Rhea-AI Summary

Dynasty Gold (TSXV: DYG) has made a significant discovery at its Thundercloud project in Ontario, identifying surface showings containing up to 50% pyrite with other sulphides in the South Pelham area, located 1.2 kilometers south of the Pelham Zone. The company has also initiated a 5,000-meter drilling program that will continue into fall 2025.

The first drill hole, TC-25-01, targets the northeastern extension of mineralization discovered in 2024, testing a substantial IP chargeability anomaly measuring approximately 500 x 500 meters. The technical team has exposed an outcrop area of 2.7m by 1.7m with up to 50% sulphide minerals, with several exposures occurring approximately 60 meters apart along a NE-SW strike direction.

Positive

• None.

Negative

• Limited rock exposure due to heavy forest and overburden cover
• Assay results from collected samples still pending

Vancouver, British Columbia--(Newsfile Corp. - September 3, 2025) - Dynasty Gold Corp. (TSXV: DYG) (FSE: D5G1) ("Dynasty" or the "Company") is pleased to announce that geologic mapping by the company has led to the discovery of several surface showings carrying up to 50% pyrite with other sulphides (see Figure 1), along the relatively unevaluated South Pelham ("SP") area, located approximately 1.2 kilometers south of the Pelham Zone. The Pelham Zone hosts a historical NI 43-101 Mineral Resource Estimate completed in 2021. Thundercloud project is situated within the Archean Manitou-Stormy Lakes Greenstone Belt, approximately 47 kilometers southeast of the town of Dryden in northwestern Ontario. Abundant pyrite and other sulphide mineral phases are the most common minerals associated with gold in the area.

The Company's drilling program has commenced. The current drill hole, TC-25-01, was positioned to test both the projected northeastward extension of the new mineralization discovered in 2024 by Hole TC24-06, which tested a strong IP chargeability anomaly of approximately 500 x 500 meters based on Teck's data that was re-modeled by Dynasty. The 5,000-meter drilling is expected to continue into the fall.

Ivy Chong, Dynasty's President and CEO, stated: "The discovery of up to 50% pyrite in surface rock exposures gives a strong indication that gold mineralization is present in this area. Pyrite is the most common sulphide associated with gold mineralization at Thundercloud. Additional drilling is required to test these targets to expand mineralization to its full extents. This initial work has increased the chances of finding other zones similar to the Pelham Zone on the Property."

The technical team is conducting detailed geologic mapping at several sites along the South Pelham trend where Teck's work in 2007 and 2008 exposed significant gold mineralization and identified several strong Induced Polarization ("IP") chargeability anomalies. Within one of the larger IP anomalies, the Dynasty team has exposed an outcrop area of 2.7m by 1.7m, with up to 50% sulphide minerals. The sulphide showing areas have limited rock exposure due to heavy forest and overburden cover on this part of the property. Several other exposures occur approximately 60 meters apart along a NE-SW strike direction and are within Teck IP anomaly zones. Samples were collected from these sites for assay.
