Summary:

The Maverick Project occurs at the boundary of the Kisseynew and Flin Flon domains. This complex boundary zone is comprised of structurally interleaved supracrustal rocks of the Flin Flon Domain and high-grade metamorphic gneisses of the Kisseynew Domain. The Project area is underlain by strongly deformed and metamorphosed para- and orthogneisses. The protoliths of the gneisses are interpreted to be supracrustal rocks of the Amisk Group, metasedimentary rocks of the Missi and Burntwood groups, and gneissose intermediate to felsic intrusives.

Maverick Project consists of the non-contiguous PL and Nokomis Properties.

PL Deposit
Gold mineralization at the PL Deposit is concentrated along the flexure in the duplex structure and the southeastern strike-extent of the D3 shear zones over a strike length of 1,200 m. The mineralization is controlled by four main shear zones that delineate the duplex structure and are named the Sherridon, Upper, Main, and Lower Zones. The shear zones and contained mineralization subcrop, under a northwest-southeast-trending swamp (i.e., Fyre Lake), have been outlined by surface diamond drilling to a vertical depth of 500 m, approximately 1,200 m down dip. The Upper, Main, and Lower Zones occur within 50 m of the sheared tonalite contact and toward the north end of the deposit, the Lower Zone is commonly hosted within the tonalite body.

The gold-bearing shear zones generally strike 330 degree and dip moderately at ........

Summary:

The PL Deposit of the Maverick Project will initially be mined by underground mining techniques as the environmental permits for this type of mining are already in effect and valid. As the PL Deposit extends to the near surface, a number of small open pits will also be developed, but environmental permitting of these operations is required. Open pit mining at lower costs, will supplement PL's underground-sourced processing plant feed.

The open pit permitting could require up to one year. After the underground mine has started mining, production from the open pits will be considered extensions of the existing operation and not subject to a federal government environmental review. The permitting and subsequent development period for the open pits has been allowed for in the overall Project mine production schedule.

Underground production will provide processing plant feed for the first 2 years. A combination of open pit and underground production will provide feed for the processing plant, while the open pits are in operation. Following completion of open pit mining, the processing plant feed will again originate exclusively from underground mine production.

The proposed mining method is Up Dip Panel Stoping, with stopes developed and mined at the inclination of the ore zones. Mining will utilize Alimak’s and slusher’s in the stopes and mobile rubber tired mining equipment elsewhere. Underground haul trucks will haul ore directly to surface via ........

Water Supply

The PL Mine has received in September 2017 a new permit to draw up to 950 cubic decimeters of water for industrial purposes under the Water Rights Act. In addition, process water will be recycled from the Ragged TMF.

The process water supply will utilize water pumped out of the underground mine as part of the mine dewatering programme. Clean service water for uses, such as gland water for pumps, firefighting, cooling circuits, etc., will be supplied directly from sources of industrial water drawn from Jay Lake.

The main losses of water will occur from water, which is not recycled, dust suppression on site roads, and evaporation.

Water for the processing plant, offices/dry complex, and the camp will be drawn from Jay Lake and all non-processing water will be treated.

The water treatment plants for both the camp and the mill/office complex will be containerized and will include filtration for suspended solids, reduction of organic colour, disinfection of the water, and distribution of the treated water to the site. Both systems will use the same treatment process and equipment to filter and disinfect the water, and both systems will have some over capacity to support future expansion, if necessary.

The camp system will need to be installed outside, so it will be supplied in a fully insulated 40 foot sea container with 2 - 5.6 m3 (1,500 gallon) tanks inside. The mine site plant will be installed within the warehouse, so it does not require winterizing. The mine site plant will be installed in a 20 foot sea container and will have a 22 m3 (6,000 gallon) poly tank installed beside it (102 inch diameter, 182 inches tall). Both plants will have Ontario ESA approval. The camp system assumes electric heating.

The treatment process is filtration using a high performance granular media backwashing filter system with Duplex Organic Colour reduction using ion-exchange resin. Primary disinfection is a duplex Upstream UV system while secondary disinfection consists of chlorine injection into the 22 m3 potable water storage tank at the mine site and the 11 m3 potable water storage at the camp.

The systems include an automatic filtration system, self-cleaning duplex UV primary disinfection systems, reliable chlorine feed pumps, water meters for keeping track of production, VFD control of distribution pumps, full duplexing of critical components, and an alarm for system faults. Each system is designed to filter +80 m3 of water per day (20 gpm maximum production rate) and deliver water at a maximum flow of 22 m3/hr (90 gpm). A 600 VAC 20 A main service supply system includes 10 kVa stepdown transformer for low voltage circuits.
