  • Some mines produced proximately 250 000 pounds of
    metal per day.

History of Mining in Newfoundland
  • After 1900 the mining industry dropped.
  • In 1905, the first discovery of iron ore is
    Buchans River.
  • In 1916, the government financed an electric
    smelting plant in St. Johns.

5
Different Mining Methods
  • Surface mining Methods
  • Placer mining
  • Dredging
  • Open-pit mining
  • Strip mining
  • Quarrying
  • Underground Mining Methods
  • Level and Shaft mining
  • Room and Pillar mining

6
Different Mines in Newfoundland
  • Wabana was an open-pit mine which mined
    iron-ore. It closed in June 30, 1966.
  • North Star Cement Limited is in Corner Brook and
    is an open-pit mine. It produced shale and gypsum
    and will exist as long as cement is needed.
  • Daniels Harbour zinc mine was an open-pit mine
    which produced zinc. It closed in 1985.

7
Different Mines of Newfoundland

  • There is now diamond drilling at Buchans.
  • There are numerous gold and base metal deposits
    in Nfld. today.

8
Uses of Minerals in Everyday Life
  • Iron is used for cars, building materials,
    airplanes and refrigerators.
  • Copper is used for electrical wires and pipes.
  • Limestone is used for pulp and paper and cement.
