Work History
Staked as Boundary Lode, etc cl (713) in May 1896 by W.R. Lloyd, T. Young, A.G. Blanchard and G.R. Voss. These and nearby claims (Devil's Canyon cl (736) staked in June 1896; Sunnyside cl (1205) staked in Sep/01 by C. Madsen and A. Anderson; Northern Lights cl (1209) staked in Oct/02 by J. Anderson; and Gold Flake, Joliette and Rimourski claims) were explored with shallow hand trenches in 1910-13.
Restaked as Lucky cl (78991) in Sep/61 by Klondike Lode Gold Mines Ltd; as Mary cl (YA10752) in Sep/77 by W. Yaremcio in conjunction with nearby placer mining; and as Mary cl 25-30 (YA55095) in Apr/81.
Noranda staked LGC cl 83-96 (YA87422) to the east in Dec/84 and carried out geochemical sampling in 1985. A joint venture between Rise Resources Ltd (60%) and Dawson Eldorado Mines Ltd (40%) surrounded the Mary cl with Gla cl 1-120 (YB5453) in Jun/88 and the partners carried out geological mapping and geochemical sampling in 1989.
Sixty Mile Enterprises trenched on the Mary claims in 1992 and in Sept/94 carried out an additional 3 285 m3 of machine trenching on the Mary cl 21 (YA47933).
In Aug/98 after optioning the Mary and other adjoining claims in the area (Minfile Occurrences #116C 020, 082 and 146), Kennecott Canada Exploration Inc staked Sixty cl 1-143 (YC12289) to the south. In 1999 Kennecott carried out prospecting, geochemical sampling and airborne geophysical surveying over their combined claim holdings and excavator trenching of six trenches (661 m) south of Miller Creek before dropping all of its options in the area the following year.
Capsule Geology
Minor amounts of galena and sphalerite occur in lensoid quartz veins that cut limy sections within weakly graphitic Late Devonian (?) to mid-Mississippian Nasina assemblage schist of the Yukon Tanana Terrane. A sample of the better mineralized material assayed 3.6% Pb, 4.4% Zn, 48.0 g/t Ag and trace Au. A silicified, dolomitized carbonate layer containing scorodite forms a persistent marker which extends northwesterly across the area. In the northwest corner of the Gla claims a porphyritic diorite plug of Tertiary age intrudes the Nasina assemblage rocks.
Noranda's claims were staked on geochemical anomalies obtained by Glasmacher but follow up work returned negative results except for two manganese stained boulders, one containing 44 ppm Ag and 3 860 ppm Pb and the other 720 ppb Au.
Contour soil sampling in the area of this occurrence by Kennecott returned two samples that were anomalous above the 90th percentile for gold (peak value of 105 ppb Au), based on a sample population of 1 224 samples collected from across the region. A second larger gold in soil anomaly that Kennecott named the Walker Fork anomaly was delineated 2.8 km to the northwest of this occurrence location. Samples collected within the area of the anomaly, which measures 500 x 500 m, had peak values of 800 ppb Au. Analysis of vuggy, chalcedonic quartz +/- graphite vein breccia float boulders, located 1 km north of the soil anomaly, returned a best result of 450 ppb Au.
