Monarch has received the final assays from its 2021 surface drilling program, which include high-grade intersections of 99.7 g/t Au over 0.6 m, 33.1 g/t Au over 0.5 m, 29.9 g/t Au over 0.7 m and 28.0 g/t Au over 0.6 m.
These positive surface drilling results continue to define reserves and potentially mineable stopes near surface in the area of the W and 350 zones. These potential stope areas are located near surface, easily accessible from a surface ramp 350 metres from the main Beaufor shaft.
This marks the completion of Monarch’s initially planned 42,500-metre Beaufor exploration drill program, which was successful at testing exploration targets defined by high-grade intersections and resource blocks near current existing underground development, both from surface and underground.
Exploration and development drilling is continuing on the property with five drills underground.
MONTREAL, Jan. 20, 2022 (GLOBE NEWSWIRE) -- MONARCH MINING CORPORATION (“Monarch” or the “Corporation”) (TSX: GBAR) (OTCQX: GBARF) is pleased to report the final results from its 2021 surface drilling program on its wholly-owned Beaufor Mine gold project, located 20 kilometres east of Val-d’Or, Québec. The results show several high-grade assays such as 46.29 g/t Au over 1.3 m (including 99.7 g/t Au over 0.6 m), 9.71 g/t Au over 2.5 m (including 33.1 g/t Au over 0.5 m), 29.8 g/t Au over 0.7 m and 28.1 g/t Au over 0.5 m. Much of the surface drilling consisted of shallow holes testing the W and 350 zones within 250 metres of surface. Monarch has reported previous surface drill results in the area, including 35.87 g/t Au over 9.8 metres and 11.02 g/t Au over 5.55 m (see press release dated January 19, 2021).

The Beaufor Mine began producing in the early 1930s and over the years has yielded over 1.1 million ounces of gold. The mine is currently on care and maintenance, which has given Monarch the opportunity to access the mine area to drill-test targets. 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, 258 holes totalling 43,419 metres have been drilled during the exploration program. Given the positive results obtained, additional holes are now being drilled to allow the zones in question to be converted into reserves and included in a future mine plan. Monarch is continuing exploration definition drilling with five underground drill rigs.
Underground development and rehabilitation are ongoing in the area of the W and 350 zones, which is easily accessible from a surface ramp located 350 metres from the main Beaufor shaft. The surface ramp providing access to the W and 350 zones presently extends to a vertical depth of 180 metres below surface.
BBA Inc. completed the mineral resource estimate for the Beaufor Mine in August 2021. An additional 25,623 metres of drilling in 105 drill holes has been completed since.
“The results of this surface drilling program are very encouraging,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “We are very pleased to be able to develop new sectors of the mine where we can define and pull mineralization elsewhere than the bottom of the mine, which was the focus in the past. This work confirms our view that the project has excellent discovery potential both underground and near surface and that there is therefore a strong possibility of increased mine resources on multiple fronts.”
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.

About Beaufor
The Beaufor Mine is located within the Bourlamaque Batholith 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 August 2021 by Charlotte Athurion, P. Geo, BBA Inc. The mineral resource estimate is listed in the table below.

Mineral resource estimate notes:
The independent qualified person for the 2021 MRE, as defined by National Instrument (“NI”) 43-101 guidelines, is Charlotte Athurion, P.Geo., of BBA Inc. The effective date of this MRE is July 23, 2021.
These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
The mineral resource estimate follows CIM definitions (2014) for mineral resources.
Results are presented diluted and considered to have reasonable prospects for economic extraction. Isolated and discontinuous blocks above the stated cut-off grades are excluded from the mineral resource estimate. Must-take material, i.e. isolated blocks below cut-off grade located within a potentially mineable volume, was included in the mineral resource statement.
The resources include 166 mineralized zones with a minimum true thickness of 2.4 m using the grade of the adjacent material when assayed or a value of 0.00025 when not assayed. High-grade capping varies from 20 to 65 g/t Au (when required) and was applied to composited assay grades for interpolation using an Ordinary Kriging interpolation method (ID2 for 96_01, 96_02, 20 zones, 21_01, 140, 367 and 350 zones) based on 1.5 m composite and block size of 5 m x 5 m x 5 m, with bulk density values of 2.75 (g/cm3). A second capping was applied for the second and third passes in order to restrict high-grade impact at greater distance.
Inferred Mineral Resources were defined for blocks within the units that have been informed by a minimum of two drillholes within 50 m of a drillhole (100 m of drill spacing); Indicated Mineral Resources were defined for blocks within the units that have been informed by a minimum of three drillholes within 12.5 m of a drillhole (25 m of drill spacing); Measured Mineral Resources were defined for blocks within the units that have been informed by a minimum of three drillholes within 5 m of a drillholes (10 m of drill spacing) or 3 m around voids. Measured Mineral Resources were only defined for zones with a good reliability of the geological continuity or supported by underground workings.
The estimate is reported for potential underground scenario at cut-off grades of 2.8 g/t Au (>=45 degree dip) and 3.2 g/t Au (<45 degree dip). The cut-off grades were calculated using a gold price of US$1,550 per ounce, a USD:CAD exchange rate of 1.32 (resulting in C$1,914 per ounce gold price); mining cost C$125/t (>=45 degree dip); C$150/t (<45 degree dip); processing cost C$35/t; G&A C$16/t; metallurgical recovery of 97%; royalties of US$37.52 per ounce; and refining and transport cost of US$1.50 per ounce.
The number of metric tonnes and ounces were rounded to the nearest hundred and the metal contents are presented in troy ounces (tonne x grade/31.10348). Rounding may result in apparent summation differences between tonnes, grades and contained metals content.
BBA Inc. is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues, or any other relevant issues not reported in this Report that could materially affect the mineral resource estimate.
