Monarch Reports High-Grade Drill Results at Beaufor Confirming the Extension of the W and 140 Zones at Depth
- Monarch has received additional high-grade assays from its 2021-2022 underground drilling program that include 37.59 g/t Au over 2.5 m, 29.79 g/t Au over 2.45 m, 21.7 g/t Au over 2.87 m, 10.09 g/t Au over 3.6 m, 418.0 g/t Au over 0.63 m and 67.1 g/t Au over 1.1 m.
- These results are from the underground drilling program currently under way in the lower and upper parts of the mine and are primarily for the W and 140 zones in the upper part of the mine.
- The results also indicate the potential extension at depth of the W and 140 zones, which are part of Monarch’s near-term mining plan using the existing ramp access.
MONTREAL, July 25, 2022 (GLOBE NEWSWIRE) — MONARCH MINING CORPORATION (“Monarch” or the “Corporation”) (TSX: GBAR) (OTCQX: GBARF) is pleased to report additional results from its 2021-2022 underground drilling program at its wholly-owned Beaufor Mine gold project, located 20 kilometres east of Val-d’Or, Québec. The recently received results are from the W and 140 zones in the upper level of the Beaufor mine, and include 37.59 g/t Au over 2.5 m, 29.79 g/t Au over 2.45 m, 21.7 g/t Au over 2.87 m, 10.09 g/t Au over 3.6 m, 418.0 g/t Au over 0.63 m and 67.1 g/t Au over 1.1 m. Positive results were also received for other areas drilled in 2021 and 2022. These results have been incorporated in the new geological model, which takes into account all recent and historical data and is based on BBA’s geological interpretation as seen in their 2021 NI 43-101 compliant resource estimate. These new positive results have prompted Monarch to continue drilling the W and 140 zones. Zone 140 has only been sparsely mined in the past, and the W Zone has well-developed infrastructure that would allow near-term production.
Commercial production at the Beaufor Mine began in the early 1930s and the mine has produced over 1.1 million ounces of gold over the years. 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. However, the depth and position of newer targets has required Monarch to drill longer holes with underground electric drill rigs and, as a result, exploration drifts for diamond drilling are being developed to allow deeper drilling and optimal interception angles and reduce overall exploration costs. Since June 2020, 335 holes totalling 54,723 metres have been drilled during the exploration and definition drilling programs. Given the positive results, 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 to drill, with five drill rigs underground.
Underground development and rehabilitation are ongoing in the W and 350 zones, which are easily accessible from the surface ramp located 100 metres from the main Beaufor shaft. The ramp presently descends to a vertical depth of 180 metres.
“We are happy with the results we are seeing so far with this program, which continues to generate strong drill results,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “In particular, these latest results confirm the high-grade nature and potential depth extension of the W and 140 zones, which are currently defined near surface and are part of our plan for near-term mining using the existing ramp. We will definitely focus our additional drilling on extending these zones at depth.”
Drill results are obtained by 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, or AGAT Laboratories in Mississauga, Ontario, for assaying. The samples are crushed, pulverized and assayed by fire assay, with atomic absorption finish. Samples exceeding 10 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 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 and amended on October 13, 2021 by Charlotte Athurion, P. Geo., Pierre-Luc Richard, P. Geo., and Dario Evangelista, P. Eng., BBA Inc. The mineral resource estimate is listed in the table below.
Table 1: 2021 mineral resource estimate for the Beaufor Mine
|Category||Tonnage (t)||Grade (g/t Au)||Ounces Au (oz)|
|Total Measured and Indicated||1,284,900||5.3||219,200|
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.
