Callinex Announces Follow-up on Silver Discoveries at the Nash Creek Project in Bathurst Mining District, New Brunswick

Highlights:

• Work underway to complete soil sampling campaign along 18 km fault to identify anomalous silver, zinc, lead and copper between two recently announced near surface silver discoveries;
• Drill hole NC20-313 intersected 28.6m of 57 g/t silver including 16.5m of 94 g/t silver and NC19-306, located 6.8 km to the south, intersected 19m of 36.53 g/t silver, 0.52% lead and 0.38% zinc; and
• A robust drilling campaign to step-out from the two silver discoveries is planned to be completed immediately once soil sampling results are received and interpreted.

VANCOUVER, July 23, 2020 - Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTC: CLLXF) is pleased to announce it plans to commence a soil sampling campaign (the "Campaign") at its 100% owned Nash Creek Project (the "Project") located within the Bathurst Mining District of New Brunswick (See Figure 1).

The Campaign will focus on covering a large portion of the 18 km Black Point Arleau Brook Fault (the "Fault") that is spatially associated with two previously announced silver discoveries located 6.8 km apart along that same fault trend (See Figure 2 and Figure 3). Drill hole NC20-313 intersected 28.6m of 57 g/t silver at a vertical depth of 120m including 16.5m of 94 g/t silver and NC19-306 which intersected 19m of 36.53 g/t silver, 0.52% lead and 0.38% zinc at a starting depth of 34.0m (See News Releases dated June 15, 2020 and June 4, 2020).

Max Porterfield, President and CEO, stated, "We are eager to get back to work in the field as we advance the two widely spaced, near surface silver intercepts at our Nash Creek Project." Mr. Porterfield continued, "The silver discoveries at Nash Creek have come at a favorable time for the Company and its shareholders. The wind is behind our sails as a number of macroeconomic factors have propelled silver prices to multi-year highs that I believe are here to stay for the foreseeable future."

The Company plans to collect approximately 1,680 soil samples for analysis of base and precious metals at a 25 metre sample spacing along section lines spaced at 100 metre intervals over the 11 km trend that encompasses both silver discoveries (See Figure 2 and Figure 3). This type of sampling method will assist the Company in vectoring towards additional high grade near surface mineralization along the controlling fault structure associated with the silver mineralization discovered in drill holes NC20-313 and NC19-306.

Limited historic regional silver, lead and zinc soil sampling has been completed by previous explorers at the Nash Creek Project. This historic data along with the newly acquired Induced Polarization survey results were utilized to target the two recently announced silver discoveries. Systematically covering the wide area between both silver intercepts will provide a wealth of information and aid in a follow-up drilling campaign.

A follow-up drilling campaign will be planned to step-out from both silver intercepts as well as test any anomalous areas of interest identified by the new soil sampling campaign.
