MONTREAL, May 06, 2026 (GLOBE NEWSWIRE) — Opus One Gold Corp (TSX-V: OOR) (the “Company” or “Opus One”) is pleased to release more assay results from the winter drilling program on its Noyell property located in the northern portion of the Abitibi greenstone belt, Quebec, Canada.
Drill Holes NO-26-06, 11 and 13 were drilled to test a possible western extension for Zone 1 at a vertical depth ranging from 350 m to 500 m. Holes NO-26-11 and 13 suffered severe deviation and ended up close to each other. The targets were reached and identified in all three holes but overall, results indicate low to moderate gold grades along the western vector of mineralization. The best result was obtained in hole NO-26-11 which returned 2.29 g/t Au over 3.28 m (true width: 2.63 m).
Drill holes NO-26-07 and 10a are infill holes in the center and eastern portion of Zone 1. Hole 7 was drilled along the main vector of mineralization of Zone 1 at a vertical depth of 480 m. Assay results confirmed the quality of the gold bearing structure in that eastern sector of Zone 1 returning 8.22 g/t Au over 8.5 m (true width: 7.16 m). That interval includes an assay of 49.1 g/t Au over 1.34 m.
Hole NO-26-10a was drilled in the center of Zone 1, at a vertical depth of 400 m, in a sector that was interpreted to be of lesser potential than the previous hole. Nevertheless, this hole returned an interval grading 5.68 g/t Au over 1.3 m (true width of: 1.08 m).
ASSAY RESULTS
Overall, these results are consistent with Opus One’s 2025 interpretation of the deposit within the Zone 1 area. More drill results will be released in coming weeks as results are slowly being received by the company.
So far, no results have been released for the West Zone as very few results have been received to date for that sector of the property where 5 holes were completed this winter.

Louis Morin, Opus One CEO commented: The main vector of mineralization, as interpreted in 2025 after our drill program, appears to be corroborated by these partial results. Zone 1 still delivers spectacular results where they were expected. This is really good news as it shows the excellent continuity of the gold bearing structure in that sector of Zone 1. The western extension did not deliver the same level of results but the zone is still there, and it could open up again a little further west. This is the style of mineralization we have to deal with. Its typically pinch and swell and the only way to find out were its swells again is to drill.
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 Fire Assay – Trace Au, ICP-OES finish (50g charge). All samples equal or above 10 g/t Au are submitted to ore grade gravimetric finish. Multi element analysis are performed using Aqua Regia Digest – Metals Package, ICP-OES 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.
