Two kilometers southeast and parallel to the Bellekeno-Keno Summit trend, the Homestake trend shows several similar features that are recognized between the two distinct mineralized trends, including the continuation of the Keno Hill Quartzites and Triassic Greenstones known to host mineralization across the district. This mineralized trend is primarily controlled by Metallic Minerals and is defined by several highly-prospective areas, namely the Homestake, Divide, Faith, Segworth and Beauvette mineralized showings. Two prominent target areas in the Homestake trend are discussed below. Three additional parallel trends are identified further east of the Homestake trend as defined by the Cobalt, Gram, Gustavus and McMillan showings.
Homestake Target Area
The Homestake target area represents one of the primary exploration targets on the Keno Silver Project. The Homestake prospective area, originally staked in 1920, is underlain by Keno Hill Quartzite and phyllitic schists of the Earn group, and locally intruded by greenstone sills. Significant grades have been returned from each of the four Homestake veins, known separately as the Homestake #1, 2, 2a veins and the Shaft vein. Between 1928 and 1931, the area was explored by a 26.8 m shaft and 38.4 m of drifting, from which a few tons of high-grade direct shipping ore were sent to a smelter. Open-pit excavation and trenching on the showing were conducted through the 1960s and ‘70s. Previous trenching at the Homestake No.1 vein (trench H-TR4) intersected 2,844 g/t Ag, 0.30 g/t Au, 25.9% Pb and 6.1% Zn across 4m. Highlighted samples are not necessarily representative of all mineralization hosted in the area. See Technical Report on the Keno-Lightning Project dated July 31, 2010 available under the Company’s profile at Sedar.com for detailed exploration data.
The Homestake Area was an area of focus for more recent work in 2007 and 2011 including trenching, soil grid sampling, structural mapping and drilling. This work returned encouraging results with Keno style mineralization encountered from drilling in 2011 with grades of 1,696 g/t Ag over 1.4 m, 1,787 g/t Ag over 0.5 m and 1,183 g/t Ag over 1.6 m in three different holes. In total, 9 holes from the 2011 drilling campaign at Homestake returned grades of over 300 g/t Ag.
The predominate mineralization style at Homestake is typical of the Keno Hill district but with significantly higher gold content in some areas including the Homestake #2 vein. Trench sampling of the Homestake #2 vein in 2011 returned channel samples up to 11.5 g/t Au over 0.35 m. Surface sampling in 2016 also returned grades of 10.62 g/t gold, 370 g/t Ag, 12.13% lead and 0.062% Zn. Selective surface sampling along the Homestake #1 vein during the fall of 2016, returned the following positive results:

Divide and Faith Target Areas
The Divide and Faith target areas show at least four veins and cover the projected southern extensions of the Caribou and Avenue Veins. The presence of multiple veins that intersect each other and are offset by faults, sets up favourable conditions for Keno Hill oreshoots. The Divide and Faith targets have received little modern exploration outside of prospecting and soil sampling and have more cover than other targets areas on the property.
A soil geochemical survey over the area in 2011 returned an 800 x 900 m gold, silver and pathfinder element anomaly. The area is a priority for further soil sampling, detailed geological mapping and trenching.
Avenue and Beauvette Target Areas
Beauvette Hill, the location of the Avenue and Beauvette targets (see Figures 3 and 4), has seen little historic work but is directly on-trend with several productive mineralized structures from the Keno Summit area and appears to be underlain by what may be a significant array of greenstone bodies. In addition to the Keno Hill deposit, the Sadie Ladue mine, which produced 12.7 Moz of silver, is an example of a greenstone hosted deposit in a similar structural setting located on the north side of the Keno Summit area2.
Avenue is an area of quartzite and greenstones that is intermittently exposed over a strike length of 1.2 kilometres which has a coincident lead, zinc and silver soil anomaly in areas typified by shallow cover. The Avenue target is on-trend with several highly-mineralized veins where they continue into what is believed to be an array of significant parallel greenstone bodies, masked under shallow cover.
Surface sampling in 2016 at Beauvette Hill area resulted in the discovery of a new sulphide-rich vein showing at a quartzite and greenstone contact.
