MONARCH MINING INTERSECTS SIGNIFICANT GOLD MINERALIZATION 1 KM SOUTH OF THE MCKENZIE BREAK DEPOSIT
Monarch Mining Corp. has intersected significant gold mineralization in several diamond drill holes approximately one kilometre south of the McKenzie Break deposit, located 25 kilometres north of the corporation’s wholly owned 750-tonne-per-day Beacon mill. This drilling is part of Monarch’s regional exploration program to test targets on the larger McKenzie Break property, outside the limits of the known deposit.
« This new discovery has the potential to become a game changer for the development of the McKenzie Break property, as it has similar geological characteristics and follows a clear high MAG trendline over a 1-kilometre stretch from the deposit, » said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. « The next steps will include testing the discovery at depth and along the proposed trendline to confirm its continuity. »
Monarch has tested the current target area, located 1 km south of the mineral resource envelope, with seven drill holes totalling 1,419 metres. Full assay results are available for the three completed holes and partial results for the remaining four holes. A list of significant assay results is presented in Table 1. Best assays include 3.93 g/t Au over 2.83 metres, followed by a second zone 85 metres further down the hole that returned 3.93 g/t Au over 5.45 metres, including 11.58 g/t Au over 1.30 metres (MK-21-281). A second hole, located 125 metres to the north, intersected 1.52 g/t Au over 8.80 metres (MK-21-287). All the remaining holes in the target area for which assay results are available have intersected anomalous gold mineralization; additional assay results for these holes are pending.
The holes were drilled to test shallow targets, typically less than 100 metres below surface, along the same intrusive/volcanic contact that hosts the McKenzie Break deposit. The property covers 9 km of this favourable contact, which is clearly defined in a recent high-resolution helicopter airborne magnetic survey completed by the Corporation (see Figure 1 and Figure 2). Follow-up drilling is warranted along the contact between the current resource and the recent results, as well as to the south.
Monarch will continue exploration drilling on the property to the end of 2021, with one drill rig drilling holes every 50 metres to extending the limits of the current McKenzie Break deposit, and also testing additional regional exploration targets.

About McKenzie Break
Gold mineralization occurs in an elongated diorite unit or lens within a shallow embayment of the Pascalis Batholith. Monarch continues to have drilling success beyond the limits of the recent resource update provided by Geologica and GoldMinds (see Table 3 and press release dated February 8, 2021). The mineralized envelope currently measures 800 metres by 650 metres and has been tested down to a vertical depth of 400 metres. The Corporation will continue drill testing the limits of the defined mineralized envelope as well as other priority targets on the property, including targets on the newly-staked claims to the south (see press release dated March 8, 2021), with its 20,000-metre drilling program, with approximately 15,765 metres drilled to date, in 45 holes. Drilling has been ongoing since April 2021, with one or two drill rigs, and is expected to continue into 2022.

Notes:
Mineral resources which are not mineral reserves do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to a Measured and Indicated Mineral Resource and must not be converted to a Mineral Reserve. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, market or other relevant issues. The quantity and grade of reported inferred resources are uncertain in nature and there has not been sufficient work to define these inferred resources as indicated or measured resources. The database used for this mineral estimate includes drill results obtained from historical records and up to the recent 2018-2020 drill program. Mineral resources are reported at a cut-off grade of 0.50 g/t Au for the pit-constrained and underground mineral resources are reported at a cut-off grade of 2.38 g/t Au within reasonably mineable volumes. These cut-offs were calculated at a gold price of C$1,980 ounce. The pit-constrained resources were based on the following parameters: mining cost $3.5/t, processing, transportation + G&A costs $27/t, Au recovery 95%, pit slopes 15 degrees for overburden and 50 degrees for rock. The underground reasonably mineable volumes were based on the following parameters: mining cost $98/t, processing, transportation + G&A costs $27/t, Au recovery 95%, dilution of 15% at 0 g/t Au with a minimum stope dimension of 10m x 10m x 5m. The geological interpretation of the deposits was based on lithologies and the typical mineralized interval mainly composed by diorite hosted shear zones. The mineral resource presented here was estimated with a block size of 5m x 5m x 5m for the pit-constrained and for underground. The blocks were interpolated from equal length composites calculated from the mineralized intervals. Prior to compositing, high-grade gold assays were capped to 60 g/t Au applied on 0.6-metre composites. The mineral estimation was completed using the inverse distance squared methodology utilizing two passes. For each pass, search ellipsoids followed the geological interpretation trends were used. Tonnage estimates are based on rock specific gravity of 2.77 tonnes per cubic metre for all the zones. Results are presented undiluted and in situ. Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348). This mineral resource estimate is dated February 1, 2021, and the effective date for the drillhole database used to produce this updated mineral resource estimate is September 28, 2020. No economic evaluation of the resources has been produced.
The resource estimate was prepared by Merouane Rachidi, P.Geo., Ph.D., and Claude Duplessis, P.Eng., of GoldMinds Geoservices Inc., both qualified persons under National Instrument 43-101.
Sampling consists of sawing the NQ-size core into equal halves along its main axis and shipping one of the halves to AGAT Laboratories in Mississauga, Ontario, for assaying. The samples are crushed, pulverized and assayed by fire assay, with atomic absorption finish. Results exceeding 3.0 g/t Au are re-assayed using the gravity method, and samples containing visible gold grains are assayed using the metallic screen method. Monarch uses a comprehensive QA/QC protocol, including the insertion of standards and blanks.
The technical and scientific content of this press release has been reviewed and approved by Louis Martin, P.Geo., the Corporation’s qualified person under National Instrument 43-101.
