Opus One Hits Deep Gold Vein, Extends Noyell Discovery to 700 Meters

MONTREAL, QC – June 17, 2026 – Opus One Gold Corp has confirmed a significant milestone in Canadian mineral exploration, announcing that its Noyell property in Quebec hosts a continuous, high-grade gold system extending to at least 700 meters below the surface. The latest results from its winter drilling program have substantially de-risked the project, validating the company's geological model and igniting investor confidence in the asset's potential.

The centerpiece of the announcement is drill hole NO-26-21a, the deepest hole drilled to date on the property's primary target, Zone 1. It returned an impressive intercept of 11.37 meters grading 4.92 grams per tonne (g/t) gold, representing a true width of 9.08 meters. This result is not just a high-grade hit; its strategic importance lies in its depth, confirming that the rich mineralization found closer to the surface persists deep underground.

De-Risking Discovery: From Surface to 700 Meters

For junior explorers, the greatest challenge—and the key to unlocking value—is proving continuity. Discovering a single pocket of high-grade gold is encouraging, but demonstrating that it is part of a large, predictable system is what transforms a prospect into a potential mine. The results from hole NO-26-21a achieve exactly that. The intercept is located a full 200 meters vertically below a previously celebrated hole, NO-26-07, which hit 8.22 g/t gold over 8.5 meters.

By connecting these two deep, high-grade data points, Opus One has confirmed a steeply dipping mineralized shoot in the eastern part of Zone 1 that is now understood to be continuous from the surface down to 700 meters. Crucially, the company reports this shoot remains “very strong and open at depth,” signaling that the system’s full extent has not yet been found.

“Our efforts and persistence are rewarded as more exciting results are coming from the Zone 1 gold bearing structure on Noyell,” commented Louis Morin, CEO of Opus One. “It is now confirmed that a high-grade gold vector is present from surface down to at least 700 m vertical as mineralization remains open at depth in that sector. Continuity is good, grade is good, thickness is good as well. It looks very encouraging for future programs we will plan to verify potential continuity.”

This confirmation of depth and continuity was met with immediate market enthusiasm, as the company’s stock (TSX-V: OOR) climbed over 18% following the news. Investors recognize that extending known mineralization by such a significant step-out reduces geological risk and dramatically increases the potential for a substantial resource estimate in the future.

Painting a Richer Picture of Zone 1

The winter drilling program, which deployed multiple rigs to drill approximately 12,000 meters, has done more than just probe the depths. The results are providing a more nuanced and complete geological portrait of the entire Zone 1 structure, which spans roughly 600 meters east-to-west.

While the eastern shoot delivered the headline result, another hole, NO-26-12, provided a pleasant surprise in the central portion of Zone 1. This area had previously been interpreted as potentially barren, but the hole returned 4.43 g/t gold over 1.88 meters at a 600-meter depth. Though narrower than the eastern intercepts, this result proves the system is more widespread than previously thought and opens up new areas for follow-up drilling.

Conversely, drilling on the western edge of Zone 1 has shown weaker mineralization. Hole NO-26-15, drilled 350 meters west of the high-grade discovery hole, returned just 0.84 g/t gold over 1 meter. This data, while not spectacular, is invaluable for the exploration team. It helps define the boundaries of the high-grade zones, allowing for more efficient and targeted future exploration focused on the most promising vectors.

The Abitibi Advantage: A World-Class Address

The Noyell property is located in the Abitibi Greenstone Belt near Matagami, Quebec—one of the most prolific and mining-friendly jurisdictions in the world. This geological belt is home to dozens of multi-million-ounce gold deposits, and its rich history provides a deep well of regional knowledge, established infrastructure, and skilled labor. For a company like Opus One, operating in the Abitibi is a significant strategic advantage that lowers logistical hurdles and accelerates development timelines.

The geology of Zone 1 appears consistent with other major Abitibi deposits. Gold mineralization is associated with sulphide minerals, primarily pyrrhotite, arsenopyrite, and pyrite. A recent study using advanced LIBS technology on core samples suggested that the gold is found in a free, finely disseminated state, which often translates to good metallurgical recovery rates during processing—a critical factor for economic viability.

Furthermore, exploration continues on other parts of the property. Five holes were completed this winter in the West Zone, located 3 kilometers from Zone 1. While assay results are still pending, initial geological observations suggest a different setting involving volcanic and intrusive rocks, hinting at the potential for an entirely separate mineralized system on the property.

Investor Confidence and the Road Ahead

The strong market reaction to the deep drill results underscores a clear narrative: Opus One is successfully executing its strategy of systematically defining a significant gold system. Despite operational headwinds common in Canadian winters, including personnel shortages and mechanical issues, the company completed the bulk of its ambitious 2026 program.

The next steps will involve integrating this wealth of new data into the geological model to refine targets for the next phase of drilling. The key question that the company and its investors now face is a thrilling one: just how deep does this high-grade system go? With the eastern shoot still wide open at depth, the logical next step will be to drill even deeper, chasing the mineralization down and testing the ultimate scale of the Noyell discovery.

As the company moves forward, the combination of high-grade intercepts, proven continuity, and a prime location in the heart of Quebec’s gold country positions the Noyell project as a key asset to watch in the junior exploration space.
