Drill Results

Callinex Intersects 67m of 2.73% Copper and 20.53m of 2.58% Copper in

Step-outs at the Rainbow Deposit in the Flin Flon Mining District, MB

Highlights:

PBM-129-W2 intersected

67.0m

of 2.73% copper highlighted by

13.0m

of 8.75% copper including

2.5m

of 17.6% copper and

6.5m

of 4.71%

copper;

PBM-131 intersected

20.53m

of 3.21% copper equivalent consisting of 2.58% copper, 0.22 g/t gold, 6.63 g/t silver and 1.11% zinc; and

The two drill holes are the widest intercepts to date in the emerging Rainbow Deposit.

VANCOUVER, BC

,

June 30, 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

(

).

The Yellow and Orange zones appear to be converging in drill hole PBM-129-W2 which intersected a broad mineralized interval that returned

67.0m

of 2.89%

copper equivalent ("CuEq") consisting of 2.73% copper ("Cu"), 0.13 g/t gold ("Au"), 3.46 g/t silver ("Ag"), 0.12% zinc ("Zn"). The Orange Zone returned

13.00m

of

9.19% CuEq consisting of 8.75% Cu, 0.39 g/t Au, 11.59 g/t Ag, 0.19% Zn including a higher grade interval of

2.50m

that returned 18.23% CuEq comprised of

17.60% Cu, 0.49 g/t Au, 24.81 g/t Ag and 0.24% Zn (

). The Orange Zone was preceded by an intersection in the Yellow Zone which

returned

6.50m

of 5.04% CuEq consisting of 4.71% Cu, 0.21 Au, 4.63 Ag and 0.40% Zn. PBM-129-W2 is located

60m

along strike to the south of PBM-113-W1

and

67m

vertically above PBM-129-W1 (

).

Max Porterfield

, President and CEO, stated, "The drill results announced today represent the two widest intersections to date at the Rainbow Deposit. These

wider intersections are typical of the pinching and swelling in Volcanogenic Massive Sulphide lenses as seen in the Orange and Yellow Zones. Drilling over the

summer will continue to focus on building a high-grade copper resource at the Pine Bay Project."

PBM-131 intersected the Orange Zone with

20.53m

of 3.21% CuEq (2.58% Cu, 0.22 g/t Au, 6.63 g/t Ag and 1.11% Zn) including

7.84m

of 5.74% CuEq (5.50%

Cu, 0.21 g/t Au, 7.17 g/t Ag and 0.11% Zn) and

14.75m

of 3.64% CuEq (2.83% Cu, 0.23 g/t Au, 8.24 g/t Ag and 1.51% Zn) (

).

Drill hole PBM-131 is

62m

vertically above PBM-113-W2 and

95m

vertically below PBM-118.

There are currently two rigs operating to expand the Rainbow closer to surface and at depth. Since the Company resumed drilling in mid-February, 19 holes

(including 2 wedges) have been announced for a total of 11,323 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.

Notes:

1.

PBM-131 collar is located at the following Universal Transverse Mercator (UTM) coordinates using the North American Datum of 1983 (NAD83) within UTM Zone 14N:331402m East and 6071286mNorth and 296.0m above sea level, and started at 296Az, -81 degree dip. PBM-129-W2

was a wedge hole (440m depth) off the (PBM-129) parent which collar was is located at the 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 290Az, -87 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.

5.

Drill hole PBM-130 was abandoned @70m due to deviation.

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

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
