Monarch Mining Reports A Significant Resource Increase At Its Mckenzie Break Property

• 44% increase in the Indicated resource to 145,982 ounces of gold and nearly 300% increase in the Inferred category to 250,593 ounces of gold
• Monarch now has 588,482 ounces of combined measured and indicated resources and 329,393 ounces of combined inferred resources from its four gold deposits in Abitibi, Québec (see Table 2 at the end of the release)
  

Montréal, Québec, Canada, February 8, 2021 – MONARCH MINING CORPORATION (“Monarch” or the “Corporation”) (TSX: GBAR) is pleased to announce an updated mineral resource estimate dated February 1, 2021, for its wholly-owned McKenzie Break project, 25 kilometres north of Val-d’Or, Québec.

Monarch acquired the McKenzie Break property from Agnico Eagle Mines Limited in 2017 and expanded the property in 2020 through additional purchase agreements with local prospectors and map staking to now stand at 133 claims covering a total area of ​​5,130.4 hectares. Located 20 kilometres north of the Beacon mill and 10 kilometres south of the municipality of Barraute, Québec, the property is accessible year-round via Route 397 and a gravel road and includes a portal and 700-metre ramp excavated in 2009.

Geologically, the property straddles the Manneville Tectonic Zone, interpreted to be the eastern extension of the Destor-Porcupine Break. Gold mineralization occurs in an elongated diorite unit or lens within a shallow embayment of the Pascalis Batholith.

The 2021 updated resource estimate follows the 2018-2020 diamond drilling programs completed by Monarch that included 75 drill holes totalling 20,037.9 metres. The 2018-2020 programs were focused on better defining and expanding the mineralization within the previously proposed pitshell and the deeper known mineralization. This new diamond drilling focused on the mineralization covering an area measuring 1,300 metres along strike by 900 metres and to a vertical depth of 455 metres.

Monarch mandated Geologica Groupe-Conseil Inc. of Val-d’Or and GoldMinds Geoservices of Québec to prepare and update the July 12, 2018, NI 43-101 Technical Evaluation Report and Resource Estimate prepared by Geologica and GeoPointCom. The 2021 updated resource estimate was calculated to present resources with both constrained pit and underground potential. The current resource estimate for Monarch indicates that:

• The resource estimate is confined to 30 parallel and stacked mineralized zones / vein structures that have been identified on the property.
• The estimated resources are reported for combined constrained pit and underground scenarios.
• The total Indicated resource stands at 1,829,097 t at 2.48 g/t Au for 145,982 ounces of gold.
• The total Inferred resource stands at 3,327,065 t at 2.34 g/t Au for 250,593 ounces of gold.
• Many of the high-grade intersections outside of the pit shell are open. It is likely that additional diamond drilling would increase the Inferred tonnage and allow some of the Inferred resources to be upgraded to the Indicated category.

The estimate is based on a database of 333 drill holes, 57,789 metres of drilling and 34,026 assays. A total of 30 mineralized envelopes were modelled and validated. Capping was applied to raw assays before compositing, with grades capped at 60 g/t Au for the mineralized zones. The independent and qualified persons for the mineral resource estimate, as defined by NI 43101, are Merouane Rachidi, P.Geo., and Claude Duplessis, Eng., of GoldMinds Geoservices.

Table 1 presents the combined resources (in-pit and underground) by category for the McKenzie Break deposit at the selected cut-off grades.

Notes:

1. 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.
2. The database used for this mineral estimate includes drill results obtained from historical records and up to the recent 2018-2020 drill program.
3. 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.
4. These cut-offs were calculated at a gold price of C$1,980 ounce.
5. 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.
6. 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.
7. The geological interpretation of the deposits was based on lithologies and the typical mineralized interval mainly composed by diorite hosted shear zones.
8. The mineral resource presented here was estimated with a block size of 5m X 5m X 5m for the pit-constrained and for underground.
9. 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.
10. 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.
11. 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.
12. Estimates use metric units (metres, tonnes and g/t). Metal contents are presented in troy ounces (metric tonne x grade / 31.10348).
13. 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.
14. No economic evaluation of the resources has been produced.

This updated mineral resource results in 44% more gold in the Indicated category and 291% more gold in the Inferred category compared to the 2018 resource estimate (Geologica, 2018). The resource in the area of the proposed pit shell was expanded due to increase drilling below and at the outer edges the proposed pit shell. The underground resource increased significantly due to the new zones discovered at depth and exploration drilling completed at 50-m centres in an attempt to define the limits on the mineralized zone.

Some of the better intersections from this recent exploration step-out drilling incorporated into the resource estimate included 32.30 g/t Au over 7.1 m in hole MK-18-205ext (see press release dated February 26, 2020) and 13.95 g/t Au over 14.35 m in hole MK-20-255 (see press release dated July 23, 2020).

The mineralized envelope has yet to be closed off and Monarch continues to drill it off at 50-m centres. Monarch has planned a 38-hole, 14,500 metre follow-up drilling program to continue to expand the limits of the known mineralization. This follow-up drilling is in progress, with results pending.  

“We are very pleased with the updated resource estimate,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “Our 2018-2020 drilling programs have allowed us to significantly expand the known mineralized envelope, which lies at a relatively shallow depth. These programs totalling 20,037.9 metres of drilling managed to add 44,401 ounces of indicated material and 186,566 ounces of inferred material, which translate to an additional 2.2 ounces of indicated resource and 9.3 ounces of inferred resource for every metre we drilled. We believe that McKenzie Break continues to hold significant exploration potential, as shown by these latest results, and we intend to develop that potential through efficient drilling programs.”

The resource estimate was prepared by Merouane Rachidi, P.Geo., Ph.D., and Claude Duplessis, P.Eng., of GoldMinds Geoservices Inc., both qualified persons in accordance with National Instrument 43-101 standards. 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.
