Sedimentary Copper deposits
Examples of deposits in this class include Kipushi (70 Mt @ 4.8% Cu, 8.8% Zn, 0.5% Pb), Kennecott (4.4 Mt @ 12.4% Cu, 95 g/t Ag), Ruby Creek (90 Mt @ 1.2% Cu). Gross metal values can be very high in these deposits.
Individual deposits can be pipe-like to tabular and are often irregular and discordant with strong elongation in one direction. Deposits can be up to several hundred metres in size and can be associated with Zn rich lenses, pods or deposits nearby. Copper mineralization is zoned vertically in many deposits with the more copper rich phases (chalcocite, bornite) closest to surface.
The Storm copper property contains most of the large and small-scale attributes and characteristics that are typical of this class of deposit
