Work History
Staked as Tart cl 1-80 (Y90229) in November, 1974 by Dynasty Exploration Ltd. as a result of anomalous silt and soil sample collected during regional reconnaissance. In 1975, the claims were transferred to Cyprus Anvil Mining Corporation which carried out prospecting, geological mapping, grid geochemical soil sampling and drilled four holes (494.7 m).
Pamicon Developments Ltd. and Equity Engineering Ltd. staked Monster cl 1-40 (YB42067) 1 km to the south (MINFILE occurrence 116B 003) in June, 1993. In June, 1996 Blackstone Resources Inc, which had acquired the Monster claims through its predecessor, carried out helicopter-borne magnetic and radiometric surveying of it claim holdings and adjacent areas. The surveying included this occurrence, although subsequent ground follow-up focused on areas to the south and east.
Regional & Property Geology
The area is situated in the southern Ogilvie Mountains and is cored by the Coal Creek Inlier, an oval shaped and east-trending window of Proterozoic clastic rocks that have been penetrated by mineralized breccias and cut by mafic sills and dikes. The Lower Proterozoic stratigraphy of the Coal Creek Inlier has been correlated by Thorkelson (2000) with that of the Wernecke Supergroup, defined by Delaney (1985), in the Wernecke Mountains located some 250 km to the east. The geological setting of the southern Ogilvie Mountains is considered highly favourable for hosting Olympic Dam type Cu-U-Au-Ag deposits.
The occurrence is underlain by Quartet and Gillespie Lake Group (Wernecke Supergroup) sedimentary rocks that have been intruded by Proterozoic hematite breccias and associated diorite intrusions.
Mineralization & Results
Anvil Mining Corporation found sphalerite with minor galena, chalcopyrite and marcasite and traces of pyrobitumen in two breccia zones cutting Middle Proterozoic dolomite. The company's best drill intersection assayed 11.2% Zn over 1.5 metres.
In 1996, the regional airborne geophysical survey outlined numerous northeast trending features in this area which were interpreted to be faults.
