Monument Announces Completion of Upscaled Phase 1 Drilling

in the Field at the Murchison Gold Project

Vancouver, B.C., September 20, 2021, Monument Mining Limited (TSX -V: MMY and FSE: D7Q1) “Monument” or the

“Company” is pleased to announce the successful completion of an upscaled Phase 1 18,000 metre air core (“AC”) and reverse

circulation (“RC”) drill program at its Murchison Gold Project in Western Australia.

Highlights

• Completion of 46 RC holes for 3,465 metres targeting the Munro Bore Extension target as well as the FLC2 and

FLC3 prospects, within the Burnakura Project Area . Hole depths ranged from 40 to 160 metres and were located

outside of the current resource areas.

• A total of 349 AC holes were completed for 10,484 metres focus ing on high quality structural targets defined from

geophysical surveys in areas of shallow cover.

• The Munro Bore mineralized structure has an extension into Monument’s tenement (“Munro Bore Extension”).

• Geological mapping and interpretation of the completed drilling is in progress, and subject to results obtained, follow

up drill programs will be planned.

• All of the samples generated from the drilling have been delivered to ALS Geochemistry, Perth, and results are

expected to be received between October and November 2021.

• A drill program consisting of over 5,500 metres of combined RC and diamond drilling (“DD”) targeting beneath

open pits along the high -grade North of Alliance (“NOA”) structure is at an advanced planning stage and selection

of a drill contractor is in progress.

Monument commenced its Phase 1 AC and RC drill program on July 3rd 2021 (as announced on July 20th 2021) and completed

it by August 21st 2021 (Figure 1).

This first phase of drilling was designed to test new high quality structural targets beneath c over for potential mineralization

that may lead to the identification of shallow stand alone or satellite gold deposits to supplement the current resource base. In

addition, the drilling tested the strike continuation at Munro Bore Extension that is adjacent to Munro Bore (not owned by

Monument). Munro Bore has estimated historical resources of 266,000t at 1.6g/t Au (reported in “ Technical Project Review

and Independent Valuation Report (Short Form) ” prepared by Giralia Resources NL and reviewed by Ravensgate Mining

Industry Consultants in January 2011).

A total of 46 RC holes for 3,465m were completed against a plan of 12 holes for 1,260m, comprised of 1,301m for the planned

Munro Bore Extension and additional 2,164m for the FLC2 and FLC3 prospects that was originally planned in the phase two.

It was brought forward to take advantage of increased drill rig availability.

A total of 349 AC holes were completed for 10,484m at the Authaal East, Burnakura South and Junction targets against a plan

of 430 AC holes for 16,680m at Munro Bore Extension, Banderol South and Junction . The targets were tested as planned

except the eastern line of the Junction target was not drilled due to steep terrain. The depth to blade refusal was generally less

than anticipated resulting in fewer metres drilled than originally planned. Drill holes were angled at 60 degrees and generally

spaced at 25m with lines spaced at between 400m to 950m.

Drill holes generally intersected lithology consistent with available mapping and included volcanic and Banded Iron

Formation (“ BIF”) sequences which are the same litholo gies that host the Alliance Mineral R esource. In addition, the

continuation of the Munro Bore mineralization could be identified by a zone of shearing, alteration, pyrite mineralization and

quartz veining.

All samples have been dispatched from site and have been received by ALS Geochemistry, Perth. Due to the backlog for gold

assays and multi-element geochemical results which the mining industry is currently experiencing, results aren’t expected to

be received until October through to the end of November. Higher priority samples have been pri oritized with the lab.

Geological interpretation of the completed Phase 1 drilling is ongoing and follow up mapping and sampling of some of the

drill lines will be planned. Interpretations will be reviewed and refined once assays are received to improve un derstanding of

the geological controls of the mineralized zones and guide phase 2 drilling program on Burnakura, which will be announced

accordingly.

A full review of all historical maps and reports is planned to be completed for the Gabanintha project. A n initial review

indicated there is a substantial amount of information that needs to be collated before regional exploration programs can be

designed. Additional pit mapping and a structural interpretation of the main Gabanintha pit area will also be comp leted to

assist in drill hole targeting underneath the existing pits.

Munro Bore Extension Target

A total of 12 holes for 1,301m of RC were drilled at the Munro Bore Extension target (Figure 2). Three lines of drilling were

completed with holes spaced between 40m and 50m to extend the tested mineralised strike length 160m, into Monument ’s

M51/178 tenement. Holes were drilled to depths from 60m to 160m.

An historical Mineral Resource at Munro Bore was reported by Giralia Resources in 2010, estimated to be 266,000t at 1.6g/t

Au. The drilling confirmed the strike continuation of this structure at a south -west orientation directly into Monument’s

M51/178 tenement. No significant drilling or evaluation of this structure within M51/178 has been previously completed.

The drilled structure is dipping to the north -east and is over 20m wide, defined by shearing , alteration, pyrite mineralization

and quartz veining. There is no indication whether economic mineralization continues along this structure into Monument’s

tenement at this stage.

FLC2 and FLC3 Prospects

The FLC2 and FLC3 targets were added to the Phase 1 drill program to take advantage of increased drill rig availability. A

total of 31 holes for 1,882m were completed at the FLC2 prospect (Figure 3) and 4 holes for 282m were completed at the

FLC3 prospect (Figure 4). Holes were drilled to depths between 40m and 95m.

The FLC2 target is located approximately 400m to the south of the Banderol pit and appears to be associated with the

southward continuation of the same structural contact that hosts the minera lization within the pit. The Banderol pit produced

an estimated 28 koz ounces of gold at 2.9g/t pre-2005 (“Updated Mineral Resource, Burnakura Project, Western Australia,

Australia NI 43-101 Technical Report” prepared by SRK, July 2018, or “July 2018 NI43-101 Technical Report”).

In addition to this main north-south trending structure, there appears to be structures orientated in a north -easterly direction,

which were also targeted by this drill program.

The FLC2 target has been previously tested with fences of RAB drilling and several shallow RC holes that identified

numerous areas of low-grade gold mineralization as well as some higher grade zones with best intersections of 10m at 3.4g/t

from hole FCPH1635 and 3m at 5.0g/t from FCPH1871. This drill program has tested beneath the higher grade intersections

into fresh rock, and will increase the understanding of the main controls on mineralization. The mineralization generally

appears to be associated with mafic and ultramafic contacts.

and completed drill hole collars at the FLC2 prospect

The FLC3 prospect is located approximately 1km to the south of the Federal City deposit and is interpreted to occur on the

southward continuation of the same structure that hosts th e mineralization there. The Federal City pit produced an estimated

1.2koz at 1.3g/t pre-2005 (July 2018 NI43 -101 Technical Report). The FLC3 prospect contains several shallo w high-grade

gold intercepts that include 10m at 10.9g/t from FCPH1526. The prospect has been previously tested with multiple lines of

RAB drilling and several shallow follow up RC holes that have not been further tested at depth . The mineralization appears

to be trending in a north -south orientation which is subparallel to litho logy and magnetic highs. The lithology consists of

ultramafic and mafics.

Figure 4: Aeromagnetic image showing the main mineralized trend and

completed drill hole collars at the FLC3 prospect

The four RC holes that were drilled were designed to test for mineralisation along strike and at depth and to confirm the

orientation of the high -grade mineralisation. The holes intersected an ultramafic sequence containing a narrow interval of

basalt that has increased deformation and alteration at some of its contacts, which may indicate the mineralization is focused

along lithological contacts.

A full listing of historical drill hole details showing intersections above 1 g/t gold for FLC2 and FLC3 and accompanying

drill collar plans are shown in Appendix 1.

Authaal East, Banderol South and Junction Targets

The Authaal East, Banderol South and Junction Targets had not been previously drilled and are high quality structural targets

defined from geophysical surveys, in areas of shallow cover.

A total of 30 holes for 1,172m were completed at the Authaal East target which is located approximately 500m to the east of

the Authaal pits (Figure 5). The Authaal pit has produced an estimated 13koz of gold at 5.7g/t and the Authaal North pit has

produced an estimated 7.1koz at 2.9g/t pre-2005 (July 2018 NI43-101 Technical Report). This drill target was added to the

drill plan after the July 20th 2021 press release.

The Authaal East target

The Authaal East target is located at the northern end of a north-south trending magnetic feature adjacent the Burnakura Shear

Zone (“BSZ”). Deposits including Banderol and Federal City are located on north-south trending magnetic features that have

been interpreted to be dilational subsidiary structures to the BSZ. There is also an existing line of drilling 320m t o the north-

east of the completed drilling that have 4 holes ending in assay values greater than 0.1 g/t.

and completed drill hole collars at the Authaal East target area.

Banderol South and Junction Targets

A total of 127 AC holes for 3,465m of drilling were completed at the Banderol South target. A reinterpretation of the detailed

aeromagnetic data identified a secondary north -south structural splay deviating off the regional north -east BSZ. The

orientation of this splay coincides with the structural orientation of mineralized quartz veins within the Banderol open pit and

is interpreted to be a continuation of the same structure.

A sequence dominated by felsic volcanics was intersected with minor granodiorite, mafics and ultramafics. Transported cover

was generally shallow and less than 1m thick.

A total of 192 holes for 5 ,847m of AC drilling were completed at the Junction target. The Junction target occurs at the

intersection of a known mineralized north -east structural zone with a north -south structure, where an east -west trending

magnetic high is observed. As the greenstone lithologies approach the east-west trending magnetic high to the south and

approach two granodiorite bodies, they are interpreted to be dragged and deformed potentially creating extensional dilatational

zones within the favorable host lithologies.

The drilling at the Junction target intercepted narrow intervals of amphibolite, mafic, ultramafic and possible BIF horizons

that are generally less than 100m wide, within a weak to moderately strained granite. Alluvial material covered the whole

target area to an average depth of 8m, providing potential to discover hidden mineralization.

The eastern most planned line was not drilled due to steep topography that would make drill rig access difficult. This area

will be further investigated and could potentially be tested by a soil samp ling program.

Quality Assurance/Quality Control

All drilling completed by Monument utilized the following procedures and methodologies and was carried out under the

supervision of Monument personnel. The drilling was carried out by Strike Drilling Pty Ltd under the supervision of

Monument’s personnel.

RC drilling used a 5.0-inch face sampling pneumatic hammer with samples collected into 60 litre plastic bags. Samples were

collected as 1m splits from the cyclone or as 4m composites from the 60 litre pla stic bags. Samples were kept dry by

maintaining enough air pressure to exclude groundwater inflow; however, a very small number of RC samples from this drill

program were moist or wet.

AC drilling used a 4.0 -inch blade and cuttings were collected in one m etre intervals and split between a calico bag and a

portion was placed onto the ground for spear sampling 4m composites. The 1m calico samples have been stored at the drill

site until assay results are received and validated. Composites returning greater t han 0.1g/t Au will be subsampled using the

1m calico bags.

Coarse reject samples for all mineralized samples corresponding to significant Au intervals will be retained and stored on-site

at the Company controlled core yard.

All drill samples were shipped to ALS Geochemistry laboratory in Wangara, WA for preparation. Sample analysis may take

place at some of ALS’s analysis lab oratories outside of Western Australia. All samples will undergo routine gold analysis

using a 50 -gram charge and fire assay with an atomic absorption finish. Selected samples will be dissolved by a four acid

digestion and then analyzed for a suite of 33 elements using an ICP-AES finish.

Quality control procedures included the systematic insertion of blanks (1 in 50 samples), duplicates (1 in 40 samples) and

sample standards (1 in 20 samples) into the sample stream at the drill site.

the Company, reviewed and approved by Roger Stangler, MEng, FAusIMM, MAIG, a Qualified Person as defined by NI43-

101, retained by Golder Associates Pty Ltd.
