NEWS RELEASE

April 6, 2022 TRADING SYMBOL: TSX-V: OOR

Opus One Gold Corp to Use Windfall Geotek AI System Technology on Its Casa

Berardi Douay Cameron gold properties located near Matagami, QC.

NOT FOR DISTRIBUTION TO U.S NEWSWIRE SERVICES OR FOR

DISSEMINATION IN THE UNITED STATES

Montreal, April, 2022 Opus One Gold Corp (TSX -V: OOR) (the “Company” or “Opus

One”); Windfall Geotek (TSX -V: WIN, OTCQB: WINKF, FSE: L7C2) (Windfall), are

pleased to announce that Windfall will create two gold signature programs on Opus One

Vezza North, Vezza Extension and Noyell projects. Windfall will assist Opus One Gold

Corporation (TSX-V: OOR) (Opus One) to find new drill targets by using its AI Mineral

Exploration Targeting technology that identifies sites showing the same signatures as

known mines and deposits. Windfall Geotek is a leader in the use of Artificial Intelligence

(AI) with advanced knowledge-extraction techniques, developed since 2005 in the mining

sector.

A first regional gold signature program will include all public information available and will

cover the Noyell, Vezza north and Vezza Extension projects.

gold showings found on those claims over the years

The second gold signature program will extract more information from a new detailed high

resolution Mag Airborne survey ordered by Opus One. This recent survey covered the

entire Casa-Berardi-Douay-Cameron properties area last February and March 2022.

The survey covered the Noyell property which hosts the gold discovery called Zone 1.

The latter was drilled in 2020 and 2021 by Opus One and has now been defined over a

strike length of over 400 m and down to the 375 m level. In addition, the geophysical

survey covered the Vezza North and Vezza Extension properties. The Vezza Extension

property is interpreted to potentially host the western extension of the former Vezza Mine

mineralized horizon.

Windfall Geotek will use its AI System with this newly generated high- resolution data.

The signature process will cover a total project area of 285 claims (10860 hectares). High

priority gold exploration targets will be identified within the best similarities to find the

same geological context of the VEZZA gold mine and Noyell property Zone1.

Louis Morin, Opus One CEO c ommented: “I followed the evolution of the Windfall AI

System since 2007. The latest results from their work seem to confirm that the targets

generated by Windfall AI technology can be very accurate with 5- 50 meters overburden.

Our first objective is to te st whether our known gold targets like Noyell Zone 1 and

neighbor Vezza mine will overlap existing targets generated by the AI System.

Subsequently, we will work on targets generated by AI technology in areas with less

historical work done in our Casa-Berardi-Douay-Cameron projects portfolio. It is of great

interest for us as our projects are located close to infrastructures, manpower and mining

friendly communities.”

Dinesh Kandanchatha, Chairman of Windfall Geotek commented: “We’re incredibly

excited to work alongside Opus One on their journey to a discovery. Mr. Morin [Opus

One CEO] truly understands the value our technology brings to the table in exploration

and has a plan ready for execution. We aim to provide his team with an unbiased view

of his properties using data, starting with the known Noyell Zone 1 and the neighbouring

Vezza mine.”

prepared under the supervision of Grigor Heba, Ph.D., P.Geo., Principal Geologist and a
