VANCOUVER, BC, June 8, 2021 /PRNewswire/ - Callinex Mines Inc. (the "Company" or "Callinex") (TSXV: CNX) (OTC: CLLXF) is pleased to announce additional drill results from the ongoing 30,000m drilling campaign to expand the high-grade copper, gold, silver and zinc Rainbow Deposit (the "Rainbow"). The Rainbow is located at the 100% owned Pine Bay Project within a mineral lease, less than 250m from a high-voltage hydroelectric power-line and 550m from a historic shaft with direct road access to processing facilities in Flin Flon, MB (District Overview Map).

PBM-129-W1 intersected the Orange Zone and returned 4.87m of 15.20% copper equivalent ("CuEq") consisting of 14.94% copper ("Cu"), 0.23 g/t gold ("Au"), 5.61 g/t silver ("Ag"), 0.15% zinc ("Zn") including a higher grade interval of 2.76m that returned 21.36% CuEq comprised of 21.00% Cu, 0.32 g/t Au, 7.83 g/t Ag and 0.20% Zn. The Orange Zone was preceded by an intersection in the Yellow Zone which returned 3.00m of 2.26% Cu. PBM-129-W1 is located 90m along strike to the south of PBM-113 and 40m vertically above PBM-129 (Rainbow Deposit Long Section).  

Max Porterfield, President and CEO, stated, "We are thrilled with these exceptionally high-grade copper intersections.  As we continue to expand the footprint of the Rainbow, we have gained a stronger understanding of the potential size and continuity of the deposit.  Two drill rigs will continue to operate through the summer months as we focus on the vertical and lateral expansion of the Rainbow." Mr. Porterfield continued, "To put our exploration results in context, the global average copper grades for copper mines is just over 0.50% and to be in the top ten highest grade copper mines in the world a deposit needs to average 4% copper or more. The mineralization intersected in the Rainbow to date are indicative of the high-grade deposits that the Flin Flon District is famous for hosting."

PBM-129 intersected the Orange Zone with 8.62% CuEq over 5.50m (8.45% Cu, 0.13 g/t Au, 2.67 g/t Ag and 0.16% Zn) including 2.50m of 15.88% Cu, 0.21 g/t Au, 4.51 g/t Ag and 0.15% Zn (Rainbow Deposit Cross Section). The Yellow Zone returned 3.35m of 3.78% CuEq (3.02% Cu, 0.44 g/t Au, 8.79 g/t Ag and 1.01% Zn). Drill hole PBM-129 is a 105m step-out to the south PBM-113 and 55m vertically above and to the north of PBM-111. PBM-113 intersected the Orange Zone with 5.00m of 8.35% CuEq (8.08% Cu, 0.20 g/t Au, 10.55 g/t Ag and 0.13% Zn) including 3.00m of 12.13% Cu, 0.27 g/t Au, 15.62 g/t Ag and 0.18% Zn; and 4.00m of 2.31% CuEq (2.21% Cu, 0.09 g/t Au, 2.28 g/t Ag and 0.04% Zn) preceded by the Yellow Zone with  9.06m of 3.72% CuEq (2.37% Cu, 0.70 g/t Au, 7.00 g/t Ag and 2.10% Zn).

Drill hole PBM-128 intersected the Orange Zone with 5.20m of 3.88% CuEq consisting of 2.71% Cu, 0.63 g/t Au, 12.41 g/t Ag and 1.63% Zn. The hole is located 400m below surface and a 62m step-out to the south of PBM-121, the most recent high-grade intersection announced at the Rainbow.

PBM-122 intersected 7.50m of 1.80% CuEq consisting of 0.27% Cu, 0.36 g/t Au, 8.76 g/t Ag and 3.15% Zn including 2.50m of 3.79% CuEq. PBM-122 is a 100m step-out above PBM-121, the most recent high-grade intersection announced at the Rainbow Deposit and defines the Rainbow deposit 300m below surface (See News Release Dated April 26, 2021). 

There are currently two rigs operating to expand the Rainbow closer to surface and at depth. Since the Company resumed drilling in mid-February, 16 holes (including 1 wedge) have been announced for a total of 10,005 meters out of a fully funded 30,000 meter budgeted drill program. Callinex will continue to provide results on an ongoing basis for the duration of the 2021 drilling campaign.

QA / QC Protocols
Individual samples were labeled, placed in plastic sample bags, and sealed. Groups of samples were then placed in security sealed bags and shipped directly to SGS lab in Vancouver, BC for analysis. Samples were weighed then crushed to 75% passing 2mm and pulverized to 85% passing 75 microns in order to produce a 250g pulverized split. 35 elements including copper, zinc, lead and silver assays were determined by Aqua Regia digestion with a combination of ICP-MS and ICP-AES finish, with over limits rerun using an ore grade analysis (two acid digest ICP-AES).  Gold was analyzed by fire assay. Specific gravity (sg) measured for each sample using the pycnometer and water and air method. QA/QC included the insertion and continual monitoring of numerous standards, blanks, and duplicates
