Callinex Commences 2023 Exploration Campaign at the Pine Bay Project Located in the Flin Flon Mining District of Manitoba

Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTCQX: CLLXF) is pleased to announce that it has commenced its 2023 drilling campaign (the "Campaign") at its Pine Bay Project (the "Project") located 16km from Flin Flon, MB (District Overview Map). Phase one of the fully funded campaign is budgeted for up to 10,000 meters of drilling that will focus on testing the Rainbow Deposit (the "Rainbow") at depth as well as follow-up on the Alchemist discovery, the Odin target area and test other recently identified exploration targets ( See news release dated January 30, 2023 ).

Two rigs have commenced drilling to test Rainbow at depth at the Project. One drill is testing the potential for the Orange and Yellow zones to continue at depth beyond the known deposit area ( Rainbow Long Section ) . A second drill rig is testing the source of a conductive borehole pulse electromagnetic anomaly off of Rainbow discovery hole PBM-111 that indicates the Orange and Yellow zones may continue to the south and vertically above.

Upon completion of initial drilling at Rainbow, two holes will be drilled to step-out vertically above and below the Alchemist deposit with the assumption that Alchemist is a steeply dipping/plunging system as similarly defined at the Rainbow, as the current geology suggests. Additionally, drilling will be completed to test target area Odin based on refined targeting provided by recently received BPEM survey data and lithogeochemical results.

The first phase of the 2023 exploration campaign is anticipated to take 3.5 months followed by processing and assaying of drill core. Upon completion of phase one of the 2023 exploration campaign, a fully funded 10,000m phase two will commence this fall based upon results.

The Company has also granted 280,000 stock options exercisable at a price of $3.15 per share to its directors, officers, employees and consultants. The options are exercisable for a period of five years and are subject to standard vesting provisions.

J.J. O'Donnell, P.Geo, a qualified person under National Instrument 43-101 and Exploration Manager for Callinex, has reviewed and approved the technical information in this news release.
