Thistle Resources uncovers stibnite in 2026 trench program at Brunswick

XRF analysis returns Antimony (Sb) values of up to 23.04%; samples submitted to ALS Global for certified analysis. Toronto, Ontario--(Newsfile Corp. - July 20, 2026) - Thistle Resources Inc. (TSXV: TRCG) (OTCQB: TRCGF) (the "Company" or "Thistle") is pleased to announce it has initiated its 2026 Antimony Trenching program at its flagship Brunswick Antimony Project in the World-Famous Bathurst Mining Camp, NB, Canada. Excavation of the trenches was conducted by Doucet Excavation, Bathurst, New Brunswick, with their locations (Figure 7) targeting the main mineralized zone and the sediment-granite contact that hosts the mineralization to determine the extent and characteristics of the system.

Ten samples have been collected along the edge of Trench area #1 at approximately UTM coordinates 288890E / 5259810N (Zone 20). The samples represent various styles of antimony mineralization including disseminations, massive blebs and quartz vein associated masses.

The XRF process included calibrating the machine and utilizing standards in the sample stream (OREAS504b, CDN-BL-10) during analysis. Each sample consisted of 1 - 6 pieces of rock chips collected at site.

As such, the samples were not homogeneous. The various pieces were analyzed in 3 separate locations and the results averaged by the Reflex XRF software. The results for Cu, Pb, Zn, As and Sb are summarized below in Table #1.

The samples have been shipped to ALS Global in Moncton for preparation and certified
