Opus One Gold Completes 2026 Drill Program at Noyell, Extending Zone 1 Gold Mineralization From Surface to Approximately 750 Metres and Remaining Open at Depth

Opus One Gold Corporation (OOR) released a final wrap-up of its 2026 drill program for the Noyell gold property, clarifying that the announcement does not constitute a new single discovery hole. The report reiterates that Zone 1 extends from the surface to approximately 750 metres in vertical depth and remains open at depth, a finding based on data previously disclosed. Key hole NO-26-21a was released on 2026-06-17, and results for the Zone West holes were made public on 2026-09-02.

The new assay information provided in this release is limited. Hole NO-26-08, designed to test the western extension of Zone 1 at approximately 300 metres vertical depth, returned marginal gold values for both Zone 1 and Zone 2. Hole NO-26-18 tested an interpreted west-dipping trend in Zone 1, returning marginal gold in that zone, while Zone 2 returned 2.34 g/t Au over 9.34 m. This Zone 2 intercept is described as unusually broad, though no true width was stated. Holes NO-26-14a, NO-26-19, and NO-26-23b tested the vertical continuation of Zone 1, intersecting the zone at anticipated positions without highlighting significant assays beyond those used to refine geological interpretation.

The release also repeats Zone West results previously disclosed on 2026-09-02, noting that five shallow holes intersected gold over approximately 800 metres of strike. Intercepts in this area mostly ranged between 0.50 g/t Au over 10.41 m and 1.34 g/t Au over 8.29 m, alongside a narrow zone of 3.48 g/t Au over 1.19 m.

Key previously reported intercepts repeated in this release include:

• NO-26-21a: 4.92 g/t Au over 11.37 m, true width 9.08 m, at about 700 m vertical depth.
• NO-26-07: 8.22 g/t Au over 8.5 m, true width 7.16 m, including 49.1 g/t Au over 1.34 m.
• NO-26-18 Zone 2: 2.34 g/t Au over 9.34 m, newly reported, no true width disclosed.

Opus One Gold Corporation (OOR) released final assay results for its drilling program, marking a routine update for the pre-resource explorer. The release did not introduce a new discovery hole, a major step-out, a resource estimate, or an economic milestone. The most significant facts were already known from prior releases in May, June, and September 2026.

The new final assays were broadly neutral to mildly weak. Key results included:

• NO-26-08 and the Zone 1 portion of NO-26-18 were marginal.
• Three other final holes hit the zone but produced no highlighted significant intercept.
• The main new positive is a 2.34 g/t Au over 9.34 m Zone 2 interval.

The stock has round-tripped from about C$0.06 in late 2025 to a high of C$0.10 in January 2026 and back to C$0.05 before this release. This movement indicates the market has not been paying a premium for the repeated 2026 depth-extension story. The release provides no new grade or scale data strong enough to alter the stock's valuation.

The quantitative unmet edge is that the company has not yet repeated the scale of the pre-2026 high-grade intercepts shown in the investor presentation. The 2026 best holes are good but materially lower in grade-by-width substance than the prior 287 g x m anchor. Because the anchor was not embedded in the current sub-C$0.06 share price, the results do not constitute a negative surprise. The expected share-price impact is likely muted, with no sustained 15% move anticipated based on the new information.
