Monarch Mining Corporation (“Monarch” or the “Corporation“) (TSX: GBAR) (OTCQX: GBARF) is pleased to announce additional results from its 2020â€’2021 42,500-metre exploration diamond drilling program on its wholly-owned Beaufor Mine gold project, located 20 kilometres east of Val-d’Or, QuÃ©bec. The results include several high-grade assays, including 119.0 g/t Au over 0.5 m within a wider zone of 18.93 g/t Au over 3.5 m, 56.1 g/t Au over 0.8 m within a wider zone of 29.53 g/t Au over 1.78 m and 45.6 g/t Au over 0.75 m within a wider zone of 27.60 g/t Au over 1.65 m, as Monarch continues to test for potential resources in proximity to the historical mine.
The Beaufor Mine initially began commercial production in the early 1930s and over the years has produced over 1.1 million ounces of gold. The mine is currently on care and maintenance, which has given Monarch an opportunity to drill-test targets throughout the mine area. In June 2020, the Corporation initiated a 42,500-metre diamond drilling program to test two types of targets: the areas around historical high-grade intersections near the existing underground infrastructure, and isolated resource blocks, which are typically defined by a single drill intersection. Both of these “near-mine” targets can often be tested from the existing underground workings, generally by holes less than 200 metres long. Currently, 275 holes are planned or are already being drilled at 25metre centres. If positive results are received, additional holes will be drilled to allow the zones in question to be converted into reserves and included in a future mine plan.
Assay results have been received for a total of 162 holes (19,394 m), representing roughly 46% of the planned metres of drilling. High-grade results previously reported from the program included 783 g/t Au over 0.2 m and 293 g/t Au over 0.5 m (see press release datedÂ October 1, 2020), 35.87 g/t Au over 9.8 m (see press release datedÂ January 19, 2021) and 187 g/t Au over 0.5 m and 151.5 g/t Au over 0.5 m (see press release datedÂ April 29, 2021).
Since the last reported results, the Corporation has drilled 42 additional underground exploration holes (4,928 m). The best results are shown in Table 2 below and illustrated in the attached figures. Several of the holes have multiple intersections due to the stacked nature of the mineralization. The intersection widths reported are core lengths and high-grade intersections have not been capped, as the vein interpretation and statistics have not been finalized for the zones.
Near-mine exploration drilling is ongoing, with four drill rigs underground and one on surface. The focus remains high-grade composites that are open along strike and existing resource blocks that contain sufficient room for expansion. The Corporation is also pleased to report that the exploration drift at the lower-most level of the mine is progressing well and the first drill station has been established. An underground drill has been mobilized to the first station and will start drill-testing the continuity of the mineralization below the lower-most level of the mine this month.
The BBA Inc. mineral resource estimate (MRE) for the Beaufor mine is in progress. This new resource estimate will incorporate much of the current 2020-2021 drilling program and will represent the first block model resource estimate for the Beaufor mine.
“The drill results continue to meet and even beat our expectations,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “All the pieces of the puzzle put in place since we purchased the Beaufor mine back in 2017, starting with our initial 3D modelling and targeting, followed by a significant near-mine exploration drilling program with consistent high-grade results and our upcoming block model mineral resource estimate, are starting to come together.”
Sampling consists of sawing the drill core into equal halves along its main axis and shipping one of the halves to ALS Canada in Val-d’Or, Quebec, and AGAT Laboratories in Mississauga, Ontario, for assaying. The samples are crushed, pulverized and assayed by fire assay, with atomic absorption finish. Samples exceeding 10.0 g/t Au are re-assayed using the gravity method and samples containing visible gold are assayed using the metallic screen method. Monarch uses a comprehensive QA/QC protocol, including the insertion of standards, blanks and duplicates.

The Beaufor Mine is located within the Bourlamaque Pluton at the eastern contact with the Dubuisson Formation. The Bourlamaque Batholith, a synvolcanic intrusion, is a major geological feature of the Val-d’Or mining camp. It is a quartziferous granodiorite cut by fine-grained diorite dykes. Gold mineralization occurs in veins associated with shear zones dipping moderately south. Mineralization is associated with quartz-tourmaline-pyrite veins resulting from the filling of shear and extension fractures. Gold-bearing veins show a close association with mafic dykes intruding the granodiorite. A National Instrument 43-101 resource estimate for the Beaufor Mine property was prepared for Monarch Mining in December 2020 by Carl Pelletier, P. Geo., InnovExplo Inc., and John Langton, P. Geo., JPL GeoServices Inc. The mineral resource estimate is listed in the table below.

Mineral Resource Estimate notes:
- The independent and qualified person for the 2020 MRE, as defined by NI 43-101, is Carl Pelletier, P.Geo. (InnovExplo Inc.), and the effective date is December 18, 2020.
- These mineral resources are not mineral reserves as they do not have demonstrated economic viability. The mineral resource estimates follow CIM Definition Standards and Guidelines.
- A capping of 68.5 g/t Au on assays was applied for zones 8, B, M, M1 and Q, and 34.25 g/t for all other zones. The DDH intercepts (min. 2.4 m) were capped at 16.5 g/t.
- The estimate method was polygonal on cross-sections with a minimum width of 2.4 m using a density of 2.75 t/m3 for the 63 mineralized zones.
- Measured resource polygons extend 8 m above and below development and up to 10 m laterally. Indicated resource polygons extend up to 20 m from DDH intercepts, along dip and along strike and a minimum of 2 polygons need to be in contact. Inferred resource polygons extend up to 40 m from DDH intercepts, along dip and along strike where a drill spacing ranges from 20 m to 40 m and/or in areas of isolated drill holes where mineralization is known.
- The reasonable prospect for an eventual economical extraction is met by having a reasonable minimum width for the polygons, a cut-off grade of 3.20 g/t Au, application of constraining volumes on the blocks (potential underground scenario) below a 30 m crown pillar. The cut-off grades inputs are: a gold price of USD1,612/oz, a CAD:USD exchange rate of 1.34; a mining cost of $100/t for the long hole method and $145/t for the room and pillar method; a processing cost of $50/t; and G&A and environment of $13/t and includes the royalty of 1.0% and a refinery charge of $5/t. The cut-off grades should be re-evaluated in light of future prevailing market conditions (metal prices, exchange rate, mining cost, etc.).
- Results are presented in situ. Ounce (troy) = metric tons x grade / 31.10348. The number of tonnes and ounces was rounded to the nearest hundred. Any discrepancies in the totals are due to rounding effects; rounding followed the recommendations as per NI 43-101.
- InnovExplo Inc. is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect the mineral resource estimate.
