Opus One Resources provides an update of its ongoing field work program

Montreal, Quebec, October 4, 2017, Opus One Resources Inc. (“Opus One” or the “Company”) (TSX-V: OOR) is pleased to announce it has completed a mechanical trenching program on the Fecteau property, located in Urban-Barry sector, as well as on the Grizzly and WinWin properties, located within Chibougamau-Chapais mining camp. Stripping sites were previously identified by prospecting, proximal to or directly above geophysical induced polarization (IP) anomalies. Trenches revealed new geological features such as mineralized shear zones and sulfides bearing quartz veins.

Detailed mapping, high resolution photo mosaics by drone, as well as systematic channel sampling for gold assaying are in progress on Fecteau, Grizzly and WinWin. The assay results are expected within a few weeks.

The CEO, Louis Morin, declared: « Since we completed the first financing, in September 2016, Opus One is very active in the field. We were able to work on several projects, including geophysical surveys completed on the Fecteau property located in Urban-Barry belt, host of the Windfall Lake deposit, as well as on the Grizzly and WinWin properties, in the Chibougamau-Chapais area. This program has allowed us to reveal several IP anomalies which are now targeted in the ongoing program. It is with a heightened interest that we continue with our trenching programs on these projects. »
