MONARCH MINING CORPORATION (TSX: GBAR) (OTCQX: GBARF) is pleased to report that it has received more high-grade results from the 2021-2022 drilling program on its wholly-owned Swanson gold project. Comprising a contiguous group of 127 map-designated claims and one mining lease covering an area of 5,125.8 ha, the Swanson property lies 65 kilometres northeast of Val-d’Or, Quebec, and just 50 kilometres north of Monarch’s wholly owned 750-tonne per day Beacon mill.
The 2021-2022 program is the first drilling done on the property since Monarch Gold acquired it from Agnico-Eagle Mines in 2017. Earlier results of the program, which included 27.79 g/t Au over 10.18 m and 0.92 g/t Au over 225.0 m, were reported in press releases dated March 30, 2022 and July 19, 2022. The positive results received to date have encouraged Monarch to continue testing the extensions of the gold mineralization along strike and at depth.
The most recent results are for hole SW-22-023, which tested the down-plunge continuity of the Swanson deposit to a vertical depth of 360 m. The hole intersected three of the interpreted mineralized lenses, all beyond the current limits of the interpreted wireframes used in the 2021 mineral resource estimate. The mineralized intersections included 7.21 g/t Au over 1.0 m, 2.5 g/t Au over 7.65 m and 117.91 g/t Au over 2.0 m, with the lower two zones contained within a 13.5 m intersection grading an average of 18.18 g/t Au (see Figure 1 and Figure 2).
The mineralization is hosted in altered and brecciated basalts interlayered with a syenite intrusion and is bordered on a larger scale by ultramafic rocks in the hangingwall and footwall. The mineralization remains open to the east and down plunge to the northeast. The 2021-2022 program was completed on August 29, at a total of 11,277 metres in 31 holes. Final assay results are still pending for 14 of the holes.
“We have now managed to define the plunge-trend of the Swanson gold deposit and are continuing to intersect significant high-grade gold mineralization beyond the currently defined mineral resource envelope,” said Jean-Marc Lacoste, President and Chief Executive Officer of Monarch. “We are confident that the remaining drill holes will also yield positive results.”
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, for assaying. The samples are crushed, pulverized and assayed by fire assay, with an atomic absorption finish. Samples exceeding 3 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 the Swanson property
Monarch holds a 100% interest in the Swanson property, which consists of one mining lease and 127 claims covering over 51.26 km2. A NI 43-101 mineral resource estimate for the Swanson property was prepared for Monarch by InnovExplo in January 2021. The estimate is based on a database of 209 drill holes (146 surface holes and 63 underground holes) and approximately 10,000 assays. The mineral resource was estimated using a minimum cut-off grade for two combined potential extraction scenarios: constrained pit and underground. Cut-off grades of 0.75 g/t Au for constrained pit and 2.40 g/t Au for underground were defined based on a gold price of CA$2,160 and an exchange rate of 1.34 USD/CAD. The independent and qualified persons for the mineral resource estimate, as defined by NI 43-101, are Christine Beausoleil, P.Geo., and Alain Carrier, P.Geo., of InnovExplo. The technical report summarizing the results of the mineral resource estimate can be viewed on Monarch’s website.
The Swanson deposit is interpreted as an intrusive-associated disseminated gold deposit located along a major regional structure. The gold mineralization is typical of other structurally controlled gold deposits associated with felsic intrusions. The deposit measures approximately 350 m along strike by 150 m wide and has currently been tested to a depth of 360 m.

|Area (cut-off grade)||Indicated resource||Inferred resource|
|In-pit (0.75 g/t Au)||1,864,000||1.76||105,400||29,000||2.46||2,300|
|Underground (2.40 g/t Au)||91,000||2.86||8,400||87,000||2.87||8,000|

Monarch Mining Corporation is a fully integrated mining company that owns four projects, including the Beaufor Mine, which has produced more than 1 million ounces of gold over the last 30 years. Other assets include the Croinor Gold, McKenzie Break and Swanson properties, all located near Monarch’s wholly owned 750 tpd Beacon Mill. Monarch owns 29,504 hectares (295 km2) of mining assets in the prolific Abitibi mining camp that host a combined measured and indicated gold resource of 666,882 ounces and a combined inferred resource of 423,193 ounces.
