Work History
Staked as Tiger & Lion cl (63523) in Sep/52 by J.R. Curry and adjoining Dale cl 9-16 (66521) in Aug/53 by S.W. Tatlock, which were hand pitted in 1953-55. Restaked as Dale cl 1-8 (72958) in Oct/56 by Dale Mountain Mines Ltd and as adjoining Ham cl 1-8 (73090) in Aug/57 by Cameron Developments Ltd who carried out EM surveying and as Ted cl 1-8, Gus cl 1-6 and Dime cl 1-8 (75324) in Oct/60 by Dakkon Inc. Dale Mountainn performed trenching and EM surveying in 1956 and drove a 180 m adit in 1958 from which 69 m were drilled. Restaked as Dymax cl (7924) in May/66 by Dymax Exploration Ltd.
P. Poggenburg restaked as L cl 1-16 (Y19983) in Sep/67, bulldozer trenched in 1968, added Lola cl 1-2 (Y42382) in Jun/70, and shipped 8.2 tonnes of hand cobbed ore in late 1968. His property was optioned to Yukon Exploration & Development Ltd in Oct/70 and transferred in Nov/70 to Ida Ore Mines Ltd, which shipped 21.3 tons of cobbed ore to East Helena the same year. It was then transferred in turn to Mineral Hill Mines Ltd and to Mark V Mines Ltd, which explored by trenching, geological mapping and grid soil sampling in 1971 and 1973, and was trenched in 1976 and 1980 by H.G. Curlett and C. Wilman.
Grant Stewart acquired the property in 1981 and explored with an EM surveying and drilled one hole (106.7 m) in 1981 and EM and magnetic surveying and drilled 5 holes (458 m) in 1982 through a private company, Loann Silver Mines Ltd. The property was acquired by Butler Mountain Minerals Ltd, which performed geological mapping, EM and geochemical surveying in 1983 and 1984 while concentrating exploration on the adjacent Lord occurrence (Minfile Occurrence #105B 001). The claims were allowed to lapse and the occurrence was restaked as Eagle cl 1-8 (YB34126) by H. Caesar in Jul/91. B. Laursen tied on Bone cl 1-2 (YB34262) to the south in Sep/91.
Fringe staking includes Snowball cl (YA11733) in Oct/76 by J. Johns, who hand trenched in 1977-78; CL cl (YA657) in Aug/76 by C. Wilman; Valley cl (YA34772) in Aug/78; and AB cl (YA46628) in Nov/79 by A. LeBlanc; X cl (YA35592) in Sep/78 by Poggenburg and A. Mercier; and Family, etc cl (YA45540) in Aug/79 by M. Sache. Wilman restaked all the fringe claims as Lola, etc cl (YA66027) in Jul/81 and transferred some of them in 1982 to G. Stewart. Butler Mountain acquired the fringe claims in 1983 and added Garrett cl (YA70074) to the east in June/83 before carrying out road construction. The adjoining Pond cl (YA68761) were transferred from Terra Nova Energy Inc to A. Black in Sep/84.
G. Lee and M. Power restaked the property as Frostbite cl 1-40 (YB46377) in Jan/94. During 1994 and 1995 Lee and Power carried out magnetic and EM surveying, excavator trenching and underground rehabilitation of the adit. In 1997 they carried out additional magnetic and EM surveying.
Capsule Geology
A strong east-trending fault zone cuts quartz diorite of the mid Cretaceous Cassiar Batholith. The shear zone is exposed in trenches over a length of 250 m. It is intruded by diabase dikes and contains pockets and stringers of galena and sphalerite in a quartz-carbonate gangue. The veins are surrounded by strong propylitic and weak argillic alteration envelopes.
The adit was collared about 200 m vertically below and 300 m east of the trenches and was driven more or less parallel to the projected strike. The underground drilling failed to intersect the mineralized structure. The 1968 shipment graded 3 531 g/t Ag and 56% Pb. The 1970 shipment averaged 2 139 g/t Ag, 49.9% Pb, 12.5% Zn, 0.3% Cu and 2.4 g/t Au. A typical specimen assayed 1 203 g/t Ag, 13.4% Pb, 12.2% Zn and 1.85 g/t Au. The 1981-82 drilling did not intersect mineralization.
Power and Lee carried out VLF-EM and total magnetic field surveys over the property in 1994. The VLF-EM survey outlined the Dale Fault while the magnetic survey outlined mafic dykes in the footwall and hanging wall of the Dale Fault. Grab samples collected from waste piles surrounding the main showing assayed up to 3 514 g/t Ag and 1.27 g/t Au. The adit was rehabilitated to allow for future exploration and/or to provide drill stations for underground drilling.
Power and Lee dug additional trenches and expanded earlier VLF-EM and total magnetic field surveys to the east in 1995. The geophysics outlined the Dale Fault and mafic dykes in the footwall and hanging wall of the fault and the corresponding occurrence of Pb-Ag mineralization. Trenching based on geophysical results uncovered additional thin discontinuous high grade Pb-Ag veins within the fault zone. The best assay, a grab sample, returned 10 131.3 g/t Ag and 1.68 g/t Au. In 1997, they extended the geophysical coverage to the east and recommended diamond drilling and trenching to further test the occurrence.
