Work History

Staked as Spotted Fawn cl (5160) in Sep/01 by C. Celine, who financed trenching in 1902-03 through a private syndicate, Twelvemile Quartz Mg & Dev C. Restaked as Galena Farm cl (6837) in Oct/03 by W.J. Elliott and Jessie cl (6999) & Melville cl (7000) in Sep/04 by Elliott & W.R. Melville. These and neighboring claims were optioned by Syndicat Lyonnais du Klondike, which drove a 55 m adit on the Jessie claim in 1905-06. A total of 10 claims were surveyed in 1907 and leased as Crown Granted claims in Sep/09.
Only the Galena Farm and Melville claims are still in good standing. They were explored in 1920 by the Spotted Fawn C and purchased later by Yukon Cons Gold Corp, which performed mapping and sampling in 1962. Numerous claims have been staked around the two leases, including Ophir, London, Jupiter, etc cl (12572) in Jun/16 by D.B. Cole and associates, who performed trenching until 1946; Keno, Radium, etc cl (57668) in May/51 by The Klondike E Synd; Snow cl (79083) in 1962 by Yukon Cons Gold Corp L, Rome cl (76544) in Mar/65 by Arivaca EL; Tom cl (87390) in May/66 by W. Kaufmann, who conducted a small geochem sampling program; and Kem cl (Yl5381) in Jun/68 by Klondike EL, which explored by trenching in 1968 and 1969, drilled several short packsack holes in 1970, started a tote road to the property in 1972, hand trenched and drilled 4 holes (36.6 m) in 1974, and hand trenched in 1976.
The fringe ground was restaked as No cl (YA32507) in May/79 and as Claim cl (YA79181) in Aug/83 by G. Hakonson.

Capsule Geology

Several lensoid, northeast-striking, siderite-galena-pyrite-arsenopyrite veins cut Mississippian Keno Hill Quartzite near a large Cretacesous syenite stock. Geochemical work indicates that four or more veins may be present. Two veins have been extensively explored, one on the Galena Farm claim and the other, on which a short adit was driven, about 0.8 km to the south. The veins have been traced about 18 m along strike and seldom exceed 0.6 m in width. An average assay is about 16% Pb and 822.8 g/t Ag , with selected specimens assaying up to 4 388.5 g/t Ag. Nine tonnes were reportedly sacked for shipment in 1920 but no smelter results are available. The 1920 report also claimed that 16 different veins were exposed across 30 m on the Ophir claim and that one of these veins was 1.2 m wide and contained a 71 cm width of massive galena.
The actual position of some of the early work and mineral showings is uncertain because of a discrepancy between the claim names used in the reports and their actual positions according to the survey plan. Cockfield (1918) stated that the southerly showing was on the Ophir claims although he did not mention an adit there. Claim sketches showed the Ophir at this location, adjoining the Galena Farm cl on the downstream (southwest) side, but the survey plan shows it adjoining on the northwest side. Hester's report mentions a short adit southwest of the Galena Farm and describes galena in ferricrete but does not mention an adit upstream (northeast) of the Galena Farm, where the Jessie claim was situated. If the 1906 adit was actually driven northeast of the Galena Farm, it has been obscured by overburden and never examined since. A sample of the ferricrete assayed in 1963 returned 164.6 g/t Ag and 5.4% Pb.
