VANCOUVER, BC

,

Sept. 7, 2021

/CNW/ -

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

(

).

PBM-138 intersected the Orange Zone and returned

37.0m

of 6.00% copper ("Cu"), 0.35 g/t gold ("Au"), 6.13 g/t silver ("Ag"), 0.09% zinc ("Zn") or 6.33%

copper equivalent ("CuEq") including two high-grade one meter intervals which returned over 18% Cu (

) . PBM-138 is located

210m

vertically above and along strike to the north of PBM-129-W2 which intersected

67.0m

of 2.73% Cu and a

34m

step-out from PBM-131 which intersected

20.53m

of 2.58% Cu (

Max Porterfield, President and CEO, stated, "We continue to be impressed with assay results coming out of the Rainbow as Callinex expands the high-grade

copper deposit. The Company recently mobilized one of the two drill rigs to define how close the Rainbow deposit comes to surface. To date the Rainbow

deposit has been intersected from

300m

vertical depth down to

890m

."

Additionally, PBM-133 intersected the Orange Zone with 2.62% CuEq over

7.71m

(1.70% Cu, 0.52 g/t Au, 8.25 g/t Ag and 1.29% Zn) including

3.21m

of 3.48%

Cu, 0.70 g/t Au, 12.18 g/t Ag and 0.98% Zn (

).

Two drill holes, PBM-135 and PBM-136, were drilled to test the down plunge extent of mineralization below discovery hole PBM-111, the deepest intersection to

date at the Rainbow. Drill holes PBM-135 and PBM-136 have been interpreted to have gone above and below the plunge line. Additional drilling is required to

further delineate the deposit at depth.

One rig is currently drilling to test the up plunge extent of the Rainbow deposit above

300m

vertical depth. A second drill rig is operating to test regional

exploration targets to the north and along strike of the Rainbow Deposit, while vectoring with borehole electromagnetic surveys. Since the Company commenced

its 2021 exploration campaign, 27 holes (including 5 wedges) have been announced for a total of 18,700 meters out of a fully funded 30,000 meter budgeted drill

program. Callinex will continue to provide results for the duration of the 2021 drilling campaign.

following Universal Transverse Mercator (UTM) coordinates using the North American Datum of 1983 (NAD83) within UTM Zone 14N: 331378m East and 6071255m North and 295.0m above sea level, and started at 292Az, -80 degree dip.

2. The size of the drill core is NQ.

3.True Width calculations assumed the Rainbow Horizon to strike 032 degrees azimuth, with a 80 degree easterly dip.

4. All CuEq (copper equivalent) assay results in this news release use the following pricing: US$3.00 copper per pound ($6,720/tonne), US$1.15 zinc per pound, US$1,450/troy ounce gold ($46.62/gram), US$16.50/toy ounce silver ($0.53/gram), calculation CuEQ= Cu%+(Zn% x zinc price

per pound / copper price per pound)+(Au g/t x Au price per gram / copper price per tonne) x100 + (Ag g/t x Ag price per gram / copper price per tonne) x 100. 100% metal recoveries used, ie. no process recoveries or smelter payables were included in the calculation.

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
