Work History
Staked in Aug/74 as OZ cl 1-81 (Y89931) by Dynasty Explorations Limited, which conducted mapping and soil and rock geochem sampling later in the year.
In 1975, the OZ group was transferred to Cyprus Anvil Mining Corp, which drilled 3 holes totalling 379.5 m and completed grid soil sampling, mapping and hand trenching
Restaked as Harp cl 1-24 (YA64908) in Feb/82 by Enterprise Exploration Limited and transferred to U. Schmidt & E. Jensen, who prepared a topographic map in 1985. In Mar/91, the claims were transferred to U. Schmidt, who staked Harp cl 11-42 (YB40149). In Jul/95 the remaining surviving Harp claims (YA64908) were transferred to Jensen.
1 km to the north the following year Schmidt completed a property site map showing the location of claim posts, trenches and old drill hole locations. Schmidt also completed grid soil sampling, a radiometric survey and prospecting program. In Dec/96 the Corn claims were optioned to Atna Resources Ltd.
In Jun/96, High Sense Geophysics Ltd. under contract to Equity Engineering Limited flew a regional, helicopter borne, magnetic and radiometric survey over most of the Coal Creek Inlier, but no new claims were staked.
Capsule Geology
This occurrence is underlain by Middle Proterozoic Pinguicula Group siliceous carbonate rocks, Middle Proterozoic Wernecke breccias and mafic intrusive rocks (Hart River ?); and Lower Proterozoic Gillespie Lake orange weathering silty carbonates and shales (Thorkelson, 2000).
The area is noted to host two types of mineralization. The first reported as lead-zinc mineralization in stratabound sulphides occuring in a 1.5 to 15 m thick bed of black shale, argillite and chert containing bands and disseminated grains of galena and minor sphalerite with occasional barite. This type of mineralization is thought to reflect a sedimentary origin although best grades (up to 30% Pb + Zn with 102.9 g/t Ag) were found in brecciated zones related to faulting. The best assay from the 1975 drilling, which tested the central of three showings, was 2.2% Pb + Zn over 1.5 m. Also, dolomite breccias in adjacent rocks contain fracture fillings of calcite, barite and red-brown-yellow sphalerite with minor galena. These appear to be related to faulting.
The second type of mineralization reports lead-zinc-copper mineralization suspected to originate from the Wernecke Breccia unit. During Schmidt¿s 1996 program a ¿heart-shaped¿ breccia pipe was confirmed from local float with chalcopyrite mineralization and alteration similar to Wernecke breccias. Anomalous soils over the area assayed as high as 1181 ppm Pb, 1704 ppm Zn, 1.8m ppm Ag, and 127 ppm Cu.
The regional airborne geophysical survey outlined numerous northeast trending features which were interpreted to be faults..
