LONGUEUIL, QC

Nov. 22, 2021

/CNW Telbec/ -

Azimut Exploration Inc.

("Azimut" or the

"Company") (TSXV: AZM) is pleased to report excellent preliminary metallurgical tests from two

representative samples from the Patwon Gold Zone on the Company's

100% owned Elmer

Property

(the "Property") in the

James Bay

region of

Quebec

.

The test program conducted by SGS Canada Inc. included chemical and metallurgical

characterization, comminution, and metallurgical testing. The objective was to obtain baseline

grindability and recovery data for a gravity separation and gravity tailings cyanidation flowsheet.

Azimut has undertaken a 20,000-metre core drilling program to expand the Patwon Zone and

prepare for a maiden NI 43-101 compliant resource estimate (

see press release of October

18, 2021

). The Patwon mineralized body presents a remarkably thick and continuous geometry

currently defined over a strike length of 500 metres and to a minimum depth of 450 metres with an

estimated true width averaging 35 metres. The core zone of this envelope, defined thus far by 25

drill hole intercepts, displays an average true width of 45 metres at an average grade of

2.86 g/t Au. The true width of the core zone can reach up to 82 metres (

see press release of

November 4, 2021

).

HIGHLIGHTS

The preliminary metallurgical tests for the Patwon Gold Zone indicate non-refractory

free-milling gold mineralization that is potentially easily recoverable by a combination of

gravity circuit and conventional cyanide leaching.

Combined gold recoveries

for

gravity and cyanidation

reached

94%

and

93%

for two

samples grading 3.92 g/t Au (sample MET-1) and 2.95 g/t Au (MET-2), respectively.

Gravity tests

resulted in a

gold recovery of 27%

fo MET-1 and

37%

for MET-2. These

excellent recoveries indicate the potential to include a gravity circuit in a process flowsheet.

Whole-gold extractions from

cyanide leaching

range from

88% to 93%

for MET-1 and from

91% to 95%

for MET-2. Gold recovery rates are very fast for the first 2 hours. The particle size

in the range studied (between 50 and 81 µm) does not appear to have a significant impact on

the speed of gold extraction.

Very low graphitic carbon values

(below the assay detection limit of 0.05%) suggest that a

carbon-in-pulp process might be preferable to carbon-in-leach for downstream gold recovery.

Comminution tests

(ball mill grindability) returned average Bond Work Index (BWI) values that

categorize MET-1 as

medium

and MET-2 as

moderately soft

.

More testwork will be undertaken to improve the 24- to 48-hour gold recoveries and optimize the

leach residence time. Improvements are expected with these tests. Cyanide and lime consumptions

are reasonable but could likely be reduced with further optimization.

Testwork Summary

SGS Canada Inc. conducted the tests in

Quebec City

using two representative composite drill core

samples corresponding to the following holes:

ELM20-031: 13.3 kg

(sample from 172.5 m to 188.6 m along core)

ELM20-51A: 17.2 kg

(sample from 198.15 m to 220.5 m along core)

Each composite was stage-crushed to P

100

of 6 mesh (3.35 mm), blended, and submitted for a

Bond ball mill grindability test (closing screen size of 150 µm). The remaining material from each

composite was stage-crushed to P

100

passing 10 mesh (2 mm), blended, and riffled into charges for

metallurgical testwork.

Semiquantitative ICP Scan Analysis

Representative 75-micron pulverized samples were submitted for an ICP scan analysis. The two

samples (MET-1, MET-2) were found to contain mostly silica (71.2%, 61.0%) and sulphur (0.92%,

1.41%) with negligible graphitic carbon (<0.05%).

Screened Metallics Protocol

The gold and silver head grades for the two composites were determined by screened metallics

tests conducted at 106 µm. The gold head grades obtained are 3.92 g/t Au for MET-1 and 2.95 g/t

Au for MET-2. The silver content is <0.5 g/t for both samples.

Mineralogy

Based on the QEMSCAN results, pyrite is the major sulphide mineral. Pyrite is well liberated (>90%)

and the remaining pyrite is mainly associated with silicates. The gangue is mainly composed of

quartz, feldspar, chlorite and mica.

Comminution

The hardness of the mineralized samples is measured through grindability testing. This step is very

important as it might affect the mining process plant design. Comminution testing performed in this

program included a single Bond ball mill grindability test on each sample to provide initial baseline

information on the Patwon Zone. The grindability test was completed at a closing screen size of

150 µm. Referring to the SGS database, the grindability of the two samples can be categorized as

medium for MET-1 with a BWI of 13.8 kWh/t, and moderately soft for MET-2with a BWI of 13.3

kWh/t.

Metallurgical Testing: Gravity Separation

The two samples were submitted to standard gravity separation for the recovery of free gold. The

tests were performed at a target grind size P

80

of 125 microns. The gravity separation was

performed using a Knelson concentrator and a Mozley mineral separator. Gold recovery reached

27% for MET-1, yielding a gold concentrate grade of 532 g/t, and 37% for MET-2, for a grade of

643 g/t.

Summary of Cyanidation Test Results

The results from the cyanidation tests from the whole mineralized samples, ground to different

particle sizes show gold extractions ranging from 88% to 93% for MET-1 (tests CN-1 to CN-3) and

from 91% to 95% for MET-2 (tests CN-5 to CN-7). These results show that the particle size in the

range studied (between 50 and 81 µm) does not have a significant impact on gold extraction.

The final gold extractions for the gravity tailing cyanidation tests on MET-1 and MET-2 yielded 91%

and 89%, respectively. Based on the high amount of gold recovered by gravity (>25%),

incorporating gravity separation into the flowsheet would reduce the size and cost of a plant.

The cyanidation kinetic tests indicate very fast gold leaching rates. Between 63% and 73% of the

gold was leached from MET-1 after only 2 hours and between 58% and 68% from MET-2 during the

same time.
