CROINER GOLD PROJECT

Advanced project at the prefeasibility stage

Monarch holds a 100% interest in the Croinor Gold property, which consists of one mining lease for a total of 337 claims over a 151.88 km² area. The property is located approximately 55 km east of Val-d'Or (75 km by road) and 27 km east of Louvicourt, the nearest town.

Prefeasibility Study Highlights (January 2018)

• Based on US$1,280 gold price and CA$1.28/US$1 exchange rate
• Pre-tax IRR of 47.5%
• Proven and probable reserves: 602,994 tonnes @ 6.66 g/t
• Total production: 125,889 ounces of gold
• Total cost per ounce: US$902
• Mine life: 3.6 years (including preproduction)
• Study does not include drilling results after November 2015
• Excellent results from the 2018 26,580-metre drilling program, which may considerably improve the project’s potential

Geology

The Croinor Gold property is located in the eastern part of the Archean Abitibi Greenstone Belt in the southern Superior Province of the Canadian Shield.The Abitibi Greenstone Belt is one of the most extensive continuous expanses of low metamorphic grade Archean volcanic and sedimentary rocks in the world.

The Croinor Gold property is underlain by two major lithological packages—the dominantly volcanic Assup Domain in the north and the dominantly sedimentary Garden Island Domain in the south. The Assup Domain is further divided into the mafic volcanic Aurora Group in the south and the mafic to intermediate volcanic Assup Group in the north (dominantly mafic). The Pershing Batholith overlaps the southwest end of the property. The Croinor Gold property is transected by the Garden Island Deformation Corridor in a northwest-southeast direction, which overprints and partially follows the contact between the Assup and Garden Island domains.

Mineralization

The Croinor Gold deposit is hosted by the synvolcanic Croinor Sill. This dioritic sill is from 60 to 120 m thick and hosted within volcanic rocks of the Assup Domain. The deposit is characterized by gold-rich lenses consisting of quartz-carbonate-tourmaline-pyrite veins, altered pyritic host rock material, and/or tectonic breccia (pyritic host fragments within a quartz-carbonate-tourmaline-pyrite vein).

The mineralized lenses range from 60 to 120 m long. The lenses can generally be followed from one section to another (10 m sections) over lateral distances varying from several tens of m up to 600 m. To date, about 40 gold-rich lenses have been identified.

Other Showings

Many other showings have been explored to a degree ranging from trenching to drilling. In most cases, gold mineralization is found in vein systems within or associated with dyke, sill or pluton intrusives within the volcanics.

The known showings are Gold Bug, Croinor-Trench 2, Bug Lake, Pershon, Rocheleau-3, Rocheleau-5, T13, Kenda Pershing, Ansley, Onyx-Tavernier, Jolin and Brett-Tretheway.
