OPUS ONE Identifies Potential for Gold Rich Base Metal VHMS Type Deposits on Fecteau and Discloses Winter Drill Results

MONTREAL, June 26, 2018 (GLOBE NEWSWIRE) -- OPUS ONE Resources Inc. (the “Company” or “OPUS ONE”) – (TSX-V:OOR), is pleased to announce that recent exploration and compilation work has convinced the company that the Fecteau property hosts significant potential for gold rich base metal VHMS (Volcanic Hosted Massive Sulphides) type deposits. The Fecteau property is located in the Urban-Barry gold district where Osisko Mining recently disclosed a new resource calculation of 0.6 Moz gold indicated and 2.3 Moz gold inferred. (See Osisko Mining Inc. May 14^th 2018 press release)

In addition to its gold potential, Fecteau hosts a well-developed and folded unit of felsic volcanics that can be followed for approximately 15 km. The summit of the felsic unit is capped by a zone of sulphides (gossans with stringers to locally massive sulphide mineralization) creating strong sub-vertical EM conductors over ten (10) kilometers along the North flank of the Fecteau syncline and five (5) additional kilometers along the South flank. Although no massive sulphide deposit has yet been discovered on the property, numerous significant base metal results have been obtained at surface or in drill intercepts on the property. Among historical base metal results we note: 1.56% Zn over 5.6 m (Drill hole # FEC-98-01- GM56272); 1.6% Zn over 1.2 m (Drill hole #87-2- GM46447); 2.5% Cu, 1.85 g/t Au (Grab sample -GM58429) and 1.9% Cu, 1.08 g/t Au (Grab sample- GM48455).

The property is known for its precious metal potential as demonstrated by the six (6) gold showings discovered to date. Most of these gold showings are actually hosted by felsic units all over the property, especially close to NNE-SSW and E-W structures.

During the last winter, ten (10) drill holes totalling 1,671 m were completed with the main objective being to follow up on the discovery of a new surface gold showing exposed during the summer of 2017 stripping program (See November 28^th 2017 press release) with 50 metre systematic step outs. Other geophysical targets were also drill tested. Results show a high gold background over several metres within a sericite altered rhyolitic unit hosting a quartz vein and stockwork with 2-3% finely disseminated pyrite in the vicinity of the surface showing and over a total horizontal length of 200 metres. Holes FEC-18-02 to FEC-18-08 returned a total of 93 assays above 0,1g/t Au. The following table lists weighted averages gold values from the best mineralized intervals obtained during the winter drill program.

All holes intersected a sequence of mafic to felsic volcanics, with local sericite or black chlorite pervasive alteration. Sulfides bearing quartz veins and stockwork zones were systematically sampled for gold assaying.

A general location map of the Fecteau property with drill hole locations and a close up map of the 2017 gold showing area with traces of 2018 diamond drill holes can be found at the link indicated at the end of the release.

During the summer months, Opus One will focus its exploration effort on Fecteau towards a till survey and detailed mapping and sampling in order to define future targets.

Mr. Louis Morin, CEO, states: "Following a recent property visit, the management of the company is very pleased with the new developments on the Fecteau property. Latest results are significant as those have provided very important information as it will help our technical team in its understanding of the incredible mineral potential of the property."

Fecteau is a gold property which consists of 90 mining claims covering an area of 5,078 hectares located in the highly prospective Urban-Barry greenstone belt, 30 kilometers east of the Osisko Mining Windfall Lake and Lynx projects. The property is easily accessible via a good network of logging roads. The area is underlain by rocks of Archean age of the Fecteau formation. The property hosts 8 historical gold and base metals (Cu and Zn) occurrences with gold grades varying from 1 g/t to up to 8 g/t. The property is surrounded by Osisko Mining claims.

Samples collected during the 2018 drill program were dispatched from Chapais to Laboratoire Expert, Rouyn-Noranda for processing. Standard and blank QA-QC samples were introduced in the sample series at regular intervals in the field. All samples were processed according to Laboratoire Expert’s internal quality control procedures. They were analyzed following standard pyro-analyses technics “Fire Assay-Atomic Absorption”. Samples which returned values equal or greater than 5.0 g/t were reanalyzed by gravimetric method.

About OPUS ONE Resources Inc.

Opus One Resources Inc. is a mining exploration company focused on discovering high quality gold and base metals deposits within strategically located properties in proven mining camps, sometimes close to existing mines in the Abitibi Greenstone Belt, north-western Quebec and north-eastern Ontario – one of the most prolific gold mining areas in the world. Opus One holds assets in Val-d’Or, Matagami and Chibougamau areas. Bachelor Extension property is adjacent to Metanor Resources Inc.- Bachelor Gold Mine, Vezza Extension and Vezza North are located few kilometers West and North of Nottaway Resources Vezza Mine. Courvillle property is located east of Val D’Or.

In addition, Opus One has also optioned three properties, all easily accessible by a network of all season roads: Fecteau property, located in the Urban-Barry greenstone belt, east of Osisko Mining’s Windfall Lake deposit, currently one of the most active exploration area in Canada; Winwin property, located directly North of Iamgold’s Monster Lake property, and the Grizzly property, located 40 kilometers north-west of the city of Chapais in a similar geological setting to Northern Superior’s Croteau East project.
