Comments on the production information

  • ORIGINALLY EXPLORED BY N.P.RAILROAD, 500 FT OF UNDERGROUND DEVELOPMENT WORK 1931-32, 400 TONS OF 31.1% P205 SHIPPED. 1943-45 INTERNATIONAL MINERALS AND CHEMICAL SHIPPED 7000 TONS OF CONS AT 31.5% P205, LEFT 6500 TONS IN STOPES IN 1958 COMINCO TOOK OVER. IN 1965 THEY DEVELOPED 3 MAIN ADITS, BUILT A FLOAT PLANT AND EXTENDED A RAIL SIDING TO THE PLANT. PLANT CAPACITY WAS 300000 TONS OF FLOTATION CON PER YEAR FROM A DAILY FEED OF 1300 TONS. PLANT COST $6 MILLION. NO. 3 ADIT ON BED 3 IS 1650 AT LONG WITH 5 SHRINKAGE STOPES. NO. 2 ADIT ON BED 2 IS 265 FT LONG. NO. 1 ADIT ON BED 1 IS 50 FT LONG.

General comments

Subject category Comment text
Deposit DEPOSIT ALSO IN SECS 30, 32; AND SEC 6 T8N R12W. TOPOGRAPHIC CONDITIONS ON ALL OUTCROPS ARE EXCELLENT FOR UNDERGROUND MINING, AND THE EXTENT OF THE BEDS ABOVE CREEK LEVEL IS VERY LARGE. SEVERAL MILLION LONG TONS OF FURNACE- GRADE PHOSPHATE MAY BE PRESENT IN THE 3 BROS, ABOVE THE LEVEL OF DOUGLAS CREEK. SAMPLE LOT 1388 FROM USGS PROF PAPER 313-F IS LOCATED HERE.
