Opus One Gold Corp (TSX-V: OOR)  is pleased to announce that drill hole NO-25-06 from the winter drilling program on its 100% owned Noyell project near the town of Matagami, Abitibi, Québec, Canada, returned 5.57g/t Au over 8.4 m from 232.2 to 240.6 m. The mineralized interval represents a true width of approximately 6.6 m within the Zone 1 structure.

NO-25-06 is an in-fill drill hole which intersected Zone 1 at an approximate vertical depth of 200 m in the center of the known mineralized structure. This interval is located just about 90 m below the previously reported interval of 4.12 g/t Au over 7.3 m in hole NO-25-01. There appears to exist an excellent continuity between these two holes.

Hole NO-25-05 was drilled to test the continuity of Zone 1 at a vertical depth of 500 m in the eastern portion of the structure. Although Zone 1 was clearly intersected and identified, it only returned a marginal interval grading 1.14 g/t Au over 1.0 m (true width of 0.8m). Opus One interprets that an area of weak mineralization is present in that sector of Zone 1. This is the first of a series of holes drilled to test the depth extension of Zone 1.

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: Diamond drilling in the upper portion of Zone continues to deliver significant mineralized intervals. Grades are good, true thicknesses are good and continuity is good as well. Those results observed redefine our previous interpretation for our Noyell project. Thanks to easy accessibility and its proximity to services, our Noyell project is gradually taking shape to a totally new perspective.

Sample preparation, analysis and QAQC program

Drill core 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.
