9 Open-pit mining is a method used to mine ore that is lying close to the surface. The soil and rock that covers the ore body, or overburden, is first removed. Explosives are used to break up the rock that contains the ore. Heavy machinery is used to remove the ore. Trucks haul the ore up out of the pit to the crushing and grinding area.

23 • In BC, generates over $3 billion in revenue and $89 million in
Quick Facts • In BC, generates over $3 billion in revenue and $89 million in government taxes per year • A leading employer in BC with substantial potential to do more • 10,000 direct jobs & 20,000 indirect jobs • Pays highest wages and benefits of any industry - $81,100 per year • An environmentally and socially responsible industry • Less than 28,000 Hectares currently being used by mining which is less than 0.03% of BC's land base and mining lands are reclaimed • Annual amount of road/trail building for mineral exploration in 1993 = 103 km. Source

24 • Total hectares used by mineral exploration in 1993 - 157 hectare
Quick Facts • Total hectares used by mineral exploration in hectare • Total hectares harvested by forestry in ,599 hectares • 2001 Exploration expenditures totalled $10 Million or less than 10% of 1990 levels • In past 10 years, 2 mines closed for every 1 opened • At end of mine life, land can be put to other uses: The mining of an ore body represents the highest value use to which a hectare of land can be put: Mining - $150,000 per hectare Forestry - $5,700 per hectare Agriculture - $1,400 per hectare Parks - $42 per hectare Source
