The Project consists of the Pick Lake Deposit and the Winston Lake Deposit.

The Project occurs in Archean rocks of the Southern Superior Province which forms the core of the Canadian Precambrian Shield. It consists of a collage of Archean greenstone belts, that coalesced between 2.72 and 2.68 Ga and were intruded by a complex system of granitoid rocks that were exhumed by approximately 2.48 Ga (Percival, 2007). The Superior Province is particularly well endowed with gold, copper-zinc and nickel deposits, as well as other commodities in lesser amounts.

The Pick Lake and Winston Lake deposits and all nearby prospects are examples of metamorphosed volcanogenic massive sulphide (VMS) deposits, that form in collisional oceanic tectonic environments in areas of localised rifting (Lodge et al., 2014).

The Pick Lake deposit belongs to the bimodal mafic volcanic sub-type, also known as Canadianshield or Noranda-type VMS deposits. The deposits of this sub-type are characterised by dominating of the mafic volcanics with the felsic volcanic rocks constituting less than 25% of the sequence.

PICK LAKE DEPOSIT
The Pick Lake deposit occurs at the extreme western edge of the Winston-Big Duck Lake sequence of volcanic rocks, approximately 35 metres above a granitic contact. Aeromagnetics within the Project area depicts a distinctive “V” shaped sequence of magnetic and non- magnetic units converging to a northern “V” apex and appears remarkably s ........

The Pick Lake deposit is a narrow-vein, Volcanogenic Massive Sulphide (VMS) polymetallic orebody, which suits narrow-vein style extraction. Mechanised narrow-vein sublevel central retreat open stoping with cemented paste fill was selected as the mining method.

Owner mining is proposed for Pick Lake, as a highly skilled workforce is available in the region with a strong mining history. This will enable cost-effective, productive and timely development, which will minimise time to first ore, and with the acquisition of the fleet on a lease basis will minimise capital outlays in the pre-production period.

Ore will be mined and hauled to surface, where it will be processed at the Winston Lake site, producing both a zinc and copper concentrate for sale.

Previous mining activity at both Pick Lake and Winston Lake revolved around shaft and winze access, hence, there is existing infrastructure in terms of capital development. Due to the levels of uncertainty around their condition, and the associated economics, two alternative methods for mine access were assessed at the design stage, noting that the previous Winston Lake plant site has been identified as the prospective process plant location and the bulk of the economic mineralisation is located at Pick Lake.

Two options for ore removal were analysed One option was for the development of a decline from the process plant directly to Pick Lake and the other option was for the refurbishment ........

The processing facilities are based upon the sequential flotation of underground ore from the Pick Lake deposit to produce separate copper and zinc concentrates.

The process plant consists of a mineral processing flotation concentrator with associated services and ancillaries. The plant has been designed to take ROM ore from the underground mine and upgradethe copper and zinc bearing minerals to produce a copper concentrate, a zinc concentrate, and a barrentail.

Haul trucks will deliver underground ROM ore via the decline to the ROM pad where it will be dumped in blending 'finger' stockpiles arranged by grade, lithology and grindability to facilitate blending. A front-end loader (FEL) will be used to reclaim and tram ore from the various stockpiles to the crushing circuit. Primary ore will be blended under the guidance of the plant metallurgist to maintain a relatively constant feed grade and grindability to the process plant.
