Trident Intersects High-Grade Gold Over Significant Widths 220.00 Metres Below Historical Mine Workings at Contact Lake, Grading 8.69 g/t Gold Over 11.97m, Including 31.98 g/t Au Over 3.16m

Vancouver, BC, Sept. 17, 2026 (GLOBE NEWSWIRE) — Trident Resources Corp. (TSXV: ROCK ) (OTCQB: TRDTF ) (Frankfurt: 6BP0 ) (“Trident” or the “Company”) is pleased to provide the analytical results from the first three drillholes of the 2026 summer drill program at the Contact Lake Project in Northern Saskatchewan’s La Ronge Gold Belt (“LRGB”). Drillhole CL26050 intersected multiple parallel shear zones including a high-grade zone between 613.03m to 625.00m downhole depth consisting of 8.69 g/t Au over 11.97m, which is located 220.00 vertical metres below the lowest mine workings in the Main Zone (BK1). This high-grade intercept was from Trident’s first deep test below the Main Zone of the 2026 summer drill program and illustrates the excellent potential for further discovery well below the historical mined depths.

Drillholes CL26049 and CL26051 tested the shallower Buffer Zone, an area with low drill density located between the BK1 and BK3 zones where the Bakos Shear Zone intersects a separate north-trending shear structure. The results from these two holes demonstrate the potential for the Buffer Zone to host significant gold mineralization in an area previously assumed to be poorly mineralized.

Jon Wiesblatt, CEO of Trident Resources, commented: “These results reinforce our vision for Contact Lake and the significant opportunity that exists beyond the historical mine workings. As one of the first few deeper holes we have drilled at the Contact Lake Deposit area, CL26050 represents a breakthrough in our exploration progress. As the program advances, we see tremendous potential to add economic ounces to a future resource and continue building value across the Contact Lake Project. ”

The high-grade intersection in hole CL26050 was encountered 220.00 metres below the lowest historical mine workings in the Main Zone. The result provides important evidence that the Contact Lake mineralized system continues well below the areas mined by former operator Cameco, which reached a depth of only 340.00 metres before the operation closed in 1998 due to low gold prices. As drilling advances deeper below the Main Zone as well as along strike to the southwest and northeast, Trident continues to intersect thick, high-grade gold mineralization in areas that were not tested by historical operators.
