Opus One Gold Corp (TSX-V: OOR) is pleased to announce that drill hole NO-25-07 from the winter drilling program on its 100% owned Noyell project near the town of Matagami, Abitibi, Québec, Canada, returned 4.22g/t Au over 18.95 m from 95,75 to 114.7 m. The mineralized interval represents a true width of approximately 15 m within the Zone 1 structure.

NO-25-07 is a near surface in-fill drill hole which intersected Zone 1 at an approximate vertical depth of 80 m between hole NO-25-01 (4.12 g/t Au over 7.3 m) and hole NO-25-03 (3.79 g/t Au over 6.7 m). There appears to exist an excellent continuity between these three holes.

Hole NO-25-08a was drilled to test the continuity of Zone 1 at a vertical depth of 475 m in the central portion of the structure. Zone 1 returned an interval grading 2.34 g/t Au over 3.9 m (true width of 3.25m) from 523.9 to 527.8m. Zone 1 is not as rich as near surface intervals recently reported but it clearly shows that the gold bearing structure is still open at depth.

Hole NO-25-09 was drilled 50 m to the west of hole NO-25-07 and 50 m above NO-25-01. It returned 2.32 g/t Au over 6 m (true width of 5m) from 80.8 to 86.8m. Zone 1 is still clearly observed but it appears to be weakening towards the west, near surface. This hole also returned a value of 6.63 g/t Au over 1.2 m (true width of 1m) within Zone 2.

2025 Drill hole location and parameters to date are as follows:

2025 WINTER DRILLING RESULTS TO DATE

More assay results are expected soon.

Louis Morin, Opus One CEO commented: Hole NO-25-07 returned the best mineralized interval within Zone 1 so far on Noyell and it is close to surface. Results from NO-25-08a indicate that the structure is still open at depth and this is significant to the future of Zone 1. Thanks to easy accessibility and its proximity to services, our Noyell project is gradually taking shape to a totally new perspective.

Opus One Gold Corp. will be at The Mining Investment Event at Centre des Congres In Quebec City, June 3-5, 2025.

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.
