April 20, 2020 News Release Release #08- 2020

Monument Announces Trial Mining Results

at Peranggih Gold Prospect in Malaysia

Vancouver, B.C. Monument Mining Limited (TSX -V: MMY and FSE: D7Q1) (“Monument” or the “Compan y”) is

pleased to announce the results from the trial mining program at Peranggih Gold Prospect (“Peranggih”), 14km

north of Selinsing Gold Mine in Pahang State, Malaysia.

Peranggih is a new oxide exploration target. Gold mineralization is structurally controlled and similar to Selinsing

and Buffalo Reef mineralization in terms of both the regional geological and structural setting, hosted in a regional

shearing and faulted zone. At Peranggih Central (trial mining site), the mineralization is regionally trending NNW-

SSE at about 340-350 north azimuth.

The trial mining was carried out from February 22 to March 3, 2020, under which the bulk sample was extracted

from the higher mineralized area at Peranggih (Figure 1) and fed into the Selinsing gold processing plant to confirm

the average grade, quantify the presence of coarse gold, and test the metallurgical performance at plant scale.

Highlight of Results from Trial Mining Program

 Material mined in the stage one pit was 15,677 tonnes at an average grade of 1.22g/t, slightly lower but still

in line with 17,309 tonnes from a block model at 1.19g/t, and 17,060 tonnes from the 2018 grade control at

1.36g/t.

 Out of 15,677 tonnes of material mined, 13,047 tonnes of material was processed at a reconciled head grade

of 1.17g/t with actual recovery of 89.8% from reconciliation of opening and closing of gold in circuit based on

gold loaded onto activated carbon, physical gold recovered by electrowinning and gold in tailings, as

compared to an average assayed grade gold of 1.22g/t with recovery of 90.2% from plant sampling of mill

feed and tailings. Both gravity and leach responses were very encouraging.

Bulk Sample Drilling and Mining

The bulk samples for the trial mining were selected from the exposed mineralization in the historic mining area at

Central Peranggih, which combined easy access, favorable topography and a low stripping ratio, where a 5m x 5m

close spaced RAB grade control drilling program was completed in November 28, 2017. The drill program

successfully delineated a zone of higher grade gold material at Peranggih Central by testing an area of 150m strike

length by 80m width and 20m depth, known to contain a significant amount of coarse gold in a hydrotherm al

breccia system.

Mining of the Peranggih bulk sample material was controlled by the revised pit design developed from the block

model and the grade control drilling. Mining was conducted in 2m benches, and the bulk sample materials hauled

to the Pantos Interim Stockpile 7km south of Peranggih, and then to Selinsing plant ROM pad another 7km to the

south via the newly constructed access road. The bulk sample material mined was all free-digging with no drilling

and blasting carried out during the trial mining. The mining results are presented below in Table 1.

Volume m3 7,126 7,901 7,581 90% 94%

Grade g/t Au 1.22 1.19 1.36 102% 90%

Ounces oz. 612 664 745 92% 82%

A total of 15,677 tonnes of bulk sample material was mined at an average grade of 1.22 g/t Au. The tonnage of

bulk samples mined was 8% lower than the grade control tonnage due to a combination of topographical and

density variance. The bulk sample mined grade was 10% lower than grade control due to waste dilution in the

mined bulk sample blocks and the wider spacing of the GC drill samples.

The block model was redesigned with a shallower batter slope angle of 45 degrees compared to the original block

model with a slope angle of 70 degrees due to a heavy rain caused the high wall to collapse when striping work

commenced. The original Peranggih trial pit design planned for a total of 8,934 tonnes at 1.87g/t Au for 537

ounces.

Plant Scale Testwork

Analytical results for the calculated gold grade were based on processing the individual composited bulk samples

through Selinsing’s gold processing plant. The process plant incorporated crushing and ball milling where the

cyclone overflow reported to the leach circuit, from which carbon was taken through the elution column and gold

solution to the electrowinning cells; cyclone underflow reported to the Knelson Concentrator and concentrates

were sent to the Acacia reactor, then to electrowinning cells for final gold recovery.

Prior to the commencement of bulk sample processing, the crushed bulk sample stockpile was levelled and

surveyed; gold in circuit surveys were conducted before and after the processing campaign.

Due to the minimal amount of hard rock , the crushing plant was configured with just the jaw crusher and

secondary cone crusher in operation and the product screen was decked out with 22mm panels. The bulk sample

was crushed at an average rate of 126 tph. Feed rates of up to 149 tph were achieve d with relatively dry feed

though throughput was reduced when crushing clay-rich feed that became wet and sticky after rain causing chute

blockages. Size analyses on the crushed bulk sample materials/mill feed gave an average P80 of 9.1 mm.

A total of 13,047 dry tonnes of Peranggih bulk sample was processed over seven days at an average feed rate of

80 tph. The primary and secondary ball mills were operating with both Knelson concentrators online. The

Peranggih bulk sample was found to be relatively soft an d the average grind size P 80 was 39 microns. The mill

power consumed during the Peranggih campaign indicated a work index of a relatively low 11.8 kWh/tonne.

Knelson concentrates were harvested every 45 -60 minutes and accumulated over 12 hours before inten sive

leaching in the Acacia reactor. Caustic soda, sodium cyanide and leach accelerant was added to the Acacia strip

solution and the intensive leach cycle was completed within 12 hours. Intensive leach recovery was high, with two

test results given an average 99.3% recovery. The mass yield of gravity concentrate from Peranggih bulk sample

was not excessive and intensive leaching reverted to a daily cycle, with Knelson concentrates accumulated over

24 hours. Pregnant Acacia solution was sent to the electrowinning cells for final gold recovery. Reconciled gravity

gold recovery by the Knelson concentrators and Acacia reactor was 19.9%.

Cyclone overflow reported to the leach circuit with two leach and six CIL tanks operating for a total of 36 hours

retention time. Sodium cyanide concentration was targeted at 220 ppm in the first leach tank; hydrated lime was

added to control the slurry at pH 10.3, slightly lower than the usual pH 10.5 in order to control the higher than

normal viscosity of the Peranggih bulk samples. Leach kinetics were excellent with sampling of the leach circuit

indicating up to 78.5% gold in solution after the first leach tank, equivalent to 6 hours retention time; unit leach/CIL

recovery was 83.8% and reconciled overall leach/CIL rec overy was 69.9% (Figure 2 . Peranggih Trial Mining

Campaign – Leach Kinetics). Sodium cyanide and lime consumptions were 0.9 and 3.1 kg/tonne respectively and

considered fairly normal relative to the oxide ores extracted from Selinsing and Buffalo Reef.

Grade Reconciliation and Gold Recovery

Total gold recovery from the Peranggih bulk sample was a very encouraging 89.8% from a reconciled mill feed of

1.17 g/t Au. Check assays were carried out on samples of ball mill feed and cyclone overflow. The assayed gold in

mill feed gave an average 1.22 g/t Au and cyclone overflow (gravity tailings) was 0.96 g/t Au, indicating a gravity

recovery of 21.4%, slightly more than the reconciled recovery of 19.9%.

Assay leach/CIL recovery was calculated as 68.8%, comparing favorably with the reconciled recovery of 69.9%.

Overall total recovery was 90.2%, compared to the reconciled recovery of 89.8%. The reconciled mill feed grade

was 4.0% less than the assayed mill feed grade; for the relatively short campaign the reconciled and assa y

recoveries and grades were in reasonable agreement.

Both gravity and leach responses were very encouraging. No serious material handling problems were

encountered with the Peranggih bulk sample. Future campaigns will benefit from blending with more competent

ore from the Selinsing pits to help both materials being handled in the crushing plant and slurry characteristics in

the leach circuit.

A new grade control program is currently in the planning stage with 5,000 metres of drilling. In addition, a further

exploration drilling program has been proposed to define the extensions of the known mineralization along strike

to the Northeast and Southwest. Further mineralized materials might be fed into the mill from time to time once

the results of grade control are satisfactory.

Risk Factors

There is currently no NI 43-101 mineral resource estimate established anywhere on the Peranggih Gold Prospect.

All of the bulk sample material was removed from a single location known as Pit 1 (see Figure 1). Pit 1 was selected

because it was considered to have representative grade, and was ideally located for easy extraction. There is no

assurance that mining or bulk sampling in another location at Peranggih would result in similar gold content or

recovery.

During the sample test process through Selinsing processing plant, it is possible that preexisting gold contained in

the circuit was flushed out while processing the bulk sample. Similarly, the bulk sample could have deposit gold

residue in the circuit. It is unknown to what extent this may have contributed to inaccuracies in the results. There

is no certification as to the precision of the results and readers should use caution in their use and interpretation.
