Compass Confirms High Grades and Wide Mineralized Intervals at Massala Prospect

Toronto, Ontario--(Newsfile Corp. - May 21, 2026) - Compass Gold Corp. (TSXV: CVB) (Compass or the Company) is pleased to provide results from the first drilling fence from the recently initiated resource definition diamond drilling at the Massala prospect, located on the Company's Sikasso Property in Southern Mali ( Figure 1 ). Highlights Phase 1 drilled along 340 m mineralized zone of the approximately 3 km Tarabala fault within the Massala Small Mine Permit application area Drilling has intercepted wide zones of significant mineralization, including several higher-grade zones; remains open down-dip Visible gold present (>100 g/t Au (from 34.5 m)) Widest interval of gold mineralization was 18 m at *4.99 g/t Au (from 17.3 m), including 3.8 m @ *21.94 g/t Au (from 31.5 m) Operations at Massala continue uninterrupted, with all personnel safe and the Company continuing to monitor developments in Mali. Compass CEO, Larry Phillips, said, "Our initial results on the Massala resource area are highly encouraging.

We have intercepted wide intervals of significant gold mineralization, including several intervals with much higher gold grades. The presence of coarse visible gold in drill core now confirms the presence of "nuggety" gold at Massala. As we continue to move along strike, the closely-spaced drill holes will give us additional confidence as we work to define an initial resource along the much larger mineralized Taraba Trend." Dr. Sandy Archibald, PGeo, Technical Director , added, "I am gratified to see that our resource definitional drilling at the Massala prospect has thus far been successful in identifying and tracing narrow higher-grade structures within wide mineralized zones, previously identified by trenching and earlier deeper drilling programs at Massala.

I eagerly await the results of the next drill holes as we continue the drilling program." * The overlimit assay value (>100 g/t Au) has been capped at 100 g/t Au to calculate the mineralized interva
