Monarch Mining Files a Technical Report for Its Beaufor Mine Project

• The Beaufor Mine technical report shows an estimated Measured Mineral Resource of 328,500 tonnes grading at 5.7 g/t Au for a total of 59,900 ounces of gold and an estimated Indicated Mineral Resource of 956,400 tonnes grading at 5.2 g/t Au for a total of 159,300 ounces, a significant increase compared to the previous mineral resource estimate (see press release dated January 28, 2021).
• Inferred resource estimated at 818,900 tonnes grading 4.7 g/t Au for a total of 122,500 ounces, a 307% increase (+92,400 ounces) versus the resource estimate announced in January 2021.
• Mineral resource estimate (MRE) developed for an underground scenario using 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.
• The new MRE includes 166 mineralized zones with a minimum true thickness of 2.4 m.
• Compared to the previous MRE, the new MRE incorporates a part of the 2020?EUR'2021 drill results (+ 5,066.6 m of drilling in 22 surface diamond drillholes (DDH), and + 12,729.3 m in 131 underground DDH) and uses a block modelling methodology with the interpretation and 3D modelling of 166 mineralized zones. In the previous MRE, the mineral resource was estimated using the polygonal methodology in 2D with a total of 63 mineralized zones.
• Approximately 24,700 metres of the ongoing 42,500-metre diamond drilling program are not included in the current MRE.
