              MONTREAL, July  29, 2025  (GLOBE NEWSWIRE) -- Opus One Gold Corp (TSX-V: OOR) (the “Company” or “Opus One”)  is pleased to announce that drill hole NO-25-21 from the winter  drilling program on its 100% owned Noyell project near the town of  Matagami, Abitibi, Québec, Canada, returned 1.98 g/t Au over 11.9 m from 474.8 to 486.7 m. The mineralized interval represents a true width of approximately 10.6 m within the Zone 1 structure.
              Hole  NO-25-21 was drilled at an intermediate depth of 400 m in the eastern  portion of Zone 1. This wide interval confirms the steep eastern plunge  on Zone 1 which culminates with the excellent results obtained in hole  NO-25-13, one of the deepest holes of the campaign so far (released in  June). This hole was initially planned to intersect Zone 1 approximately  50 m deeper than it did but, strong deviation flattened the trajectory  of the hole in an unusual fashion and the depth target was not attained.  Nevertheless, this hole confirms the continuity of the mineralization  in a key area of Zone 1.
              Both holes  NO-25-20 and NO-25-22 explored the eastern extension of Zone 1 at depths  of 300 and 500 m. Both holes intersected Zone 1 but returned only  marginal results.
              These results were the last ones from the winter drilling program of 2025 on Noyell.
              2025 Drill hole location and parameters are as follows:
              
  
              2025 WINTER FINAL DRILLING RESULTS
              
  
              Louis Morin, Opus One CEO commented: "All  results of the 2025 winter drilling program on Noyell have now been  released. The program has been a real success and a game changer for  Opus One. We have discovered a significant area of strong gold  mineralization near surface and we have demonstrated that the  mineralization extends from surface, below 20 m of overburden, down to  at least 500 m vertical. In the weeks to come, we will finalize our  review of the results and propose a new interpretation for Zone 1."
              Sample preparation, analysis and QAQC program
              All  core recovered is NQ size. All samples are described, labelled, cut  (diamond saw) and bagged at Technominex’ facilities in Rouyn-Noranda.  Samples are then shipped to AGAT certified Laboratory in Val-d’Or for  preparation. Sample pulps are then shipped to various AGAT laboratories  in Canada for analysis. Samples are assayed for gold using by Fire Assay  (50g), with ICP-OES Finish. All samples equal or above 10 g/t Au are  submitted to ore grade gravimetric finish.
              Opus  One’s QAQC program consists of one control sample inserted, at  Technominex’ facility, after 9 regular samples. Control samples consist  of a certified blank and various gold grades certified material.
