Location and accuracy Hedderly-Smith (1999 [Inventory]) suggests that the most likely location of the old Park View prospect is in the NE1/4 of section 18 or the SW1/4 of section 8, T. 77 S., R. 89 E. For this record, the site is at about the center of that area, about 0.5 mile north-northeast of the center of section 18. Maas and others (1991), however, suggest that the Park View may be near the Kael Pit (CR186). If so, the prospect may be a mile or more from the location used in this record.

Geologic setting

Geologic description

As originally described by Wright and Wright (1908), the Park View deposit consists of a 5-foot-thick mineralized zone parallel to the foliation of the schist host rocks. The deposit strikes about N75W and consists of lenses and stringers of quartz and calcite. Pyrite and chalcopyrite are disseminated in the lenses and stringers and also in the wallrock. The only workings were an open cut and an 8-foot-deep pit. The mineralization was considered to be low grade. The Park View prospect has not been found in recent years in spite of considerable work in the area.
The Park View prospect is within the Kael-7 Mile Trend (CR188), and probably is similar to other deposits in it. The rocks in the area consist mainly of marble with minor chlorite schist, cut by greenstone dikes and sills. The metamorphic rocks are part of the Wales Group of Late Proterozoic and Cambrian age (Eberlein and others, 1983; Brew, 1996). The mineralization is stratiform and consists of breccia veins or zones (Hedderly-Smith, 1993, 1999 [Inventory]). The clasts of the breccia vary from fresh marble to ferroan(?) dolomite to silicified marble. The matrix is mainly quartz; locally the matrix contains up to 50 percent pyrite and chalcopyrite, but it generally contains only a few percent of sulfides.

Mineral deposit model Stratiform, gold- and copper-bearing breccia zones in marble.
Age of mineralization Deposit is younger than the Late Proterozoic or Cambrian host rocks.
Alteration of deposit Not specifically noted in the old and only published description of the deposit (Wright and Wright, 1908). If the alteration is similar to that at the other deposits along the Kael-7 Mile Trend (CR188), it consists of silicification and dolomitization of the marble host rocks.

Production and reserves

Workings or exploration The only workings when it was described in 1908 were an open cut and an 8-foot-deep pit.
