Exploration History

Originally opened by Angelstone Ltd (1962/3-1971/2), producing ' Temple White ' dimension stone from 2 quarries on lots 4 and 5. W. R. Barnes reopened the quarry on lot 4 in 1977 and produced decorative stone chips and calcium carbonate filler. They also built a processing plant in Perth. In 1981 the plant and quarry were purchased by Steep Rock Resources Inc. (a subsidiary of Pluess-Staufer A.G.) The quarry has been operated on a seasonal basis , producing 250,000 tonnes per year for year round operations of the mill (1992). Increased levels of production were expected in 1993 as stripping to the N and S of the present quarry was carrried out at that time. Plant capacity was increased above its previous 250, 000 tonnes limit. The Perth mill produced (1992) : high-grade calcium carbonate filler for the paper industry, decorative aggregate, terrazo chips, poultry grit, agricultural limestone, stucco mix and fine-grained filler for floor tile, wall joint compounds, paints and plastics. Diamond drilling was done by Steep Rock Resources Inc. at Lot 5, Con. 4, see assessment file #19, Darling Twp.
