Opus One Gold Corp has secured 11.37 meters grading 4.92 g/t gold in the Noyell area

Highlights:

Hole #26-21A has been returned 11.37 m grading 4.92 g/t gold.
Hole NO-26-21a confirms that high-grade gold mineralization in Zone 1 is continuous from the surface to the 700 m level (vertical).
This quality shot remains very strong and open at depth.
This interval is located on the same cross section but 200 meters below previously fired hole 26-07 which returned 8.22 g/t gold at an altitude of 8.5 metres (Actual width: 7.16 m).
Very few results have been received so far from drilling operations in the Western Region.

Opus One Gold Company (TSX-V: more) (“The Company” or “Opus One”) is pleased to publish further test results from the winter drilling program on its 100% owned Noyell property located in the northern part of the Abitibi greenstone belt near Matagamie, Quebec, Canada.

Hole No. 26-21A, The deepest hole drilled to date is in Area 1He came back 11.37 m grading 4.92 g/t gold (actual width 9.08 m). This hole confirms high-grade gold mineralization in Zone 1 Continuous from the surface to a level of 700 meters (vertically)This high-quality shot, along the eastern part of Zone 1, remains very strong and open at depth. This interval is located on the same cross section but 200 meters below previously fired hole 26-07 which returned 8.22 g/t gold at an altitude of 8.5 metres (Actual width: 7.16 m). Zone 2 in this hole has not been identified.

Hole NO-26-12 was drilled approximately 150 meters to the west of NO-26-21a, in the central part of Zone 1. Zone 1, intersecting 600 meters vertically, returned 4.43 g/t gold over 1.88 meters (true width: 1.68 metres). This is a better result than expected as this part of Area 1 was previously interpreted as potentially arid.

Hole NO-26-15 was drilled approximately 350 meters west of NO-26-21a and at approximately the same depth. This hole is part of a series of holes intended to test the potential vertical extension of Area 1 in its western part. Assay results confirm that Zone 1 is weak along the westerly trend returning 0.84 g/t Au over 1 m (true width: 0.74 m) between 725 and 726 metres.

Examination results

To date, no results have been released for the Western Area as very few results have been received so far for this sector of the property, with 5 holes completed this winter.

Louis Morin, CEO of Opus One, commented: Our efforts and perseverance are being rewarded as more exciting results come from the gold-bearing structure in Zone 1 at Noyell. High-grade gold transport has now been confirmed from the surface to at least 700 meters vertically, as mineralization remains open at depth in this sector. Sustainability is good, tone is good, and thickness is good too. It sounds very encouraging for future programs that we will be planning to check for possible continuity.

Sample preparation, analysis, QA and quality assurance programme

All recovered cores are of NQ size. All samples were characterized, labeled, cut (diamond saw) and packaged at Technominex’s facilities in Rouyn-Noranda. Samples are then shipped to an AGAT accredited laboratory in Val D’or for preparation. The pulp samples are then shipped to various AGAT laboratories in Canada for analysis. Samples are screened for gold using Fire Assay – Trace Au, ICP-OES Finish (50 gram charge). All samples equal to or greater than 10 g/t gold are submitted to the ore gravimetric finishing grade. Multi-element analysis is performed using Aqua Regia Digest – Metals Package, ICP-OES finish.

Opus One’s QAQC program consists of one control sample entered into the Technominex facility, following 9 normal samples. Control samples consist of certified blanks and various certified gold grades.
