Module #1, Unit #2 – Resources and Ore Deposit Formation
Deposit Type | Principal Ore Mineral(s) | Secondary Ore Mineral(s) | Name An Example of a Deposit and its Location | Grade And Tonnage Characterization Description | Typical Mining Methods | Size or Dimension of the Deposit | Shape of the Deposit | Style of Mineralization | Rock Types | Formation Description |
| Cu | Au, Ag, Mo | Pebble, Alaska | Large tonnage and relatively low grades | Surface methods and underground – Block Caving | Hundreds to thousands of meters in each dimension | Oval or spherical | Stockwork Veins | Light coloured Igneous Instrusions and surrounding country rock | Derived from hydrothermal Fluids near top of cooling magma body between 1-5 km depth. Fluids fill in cracks creating a stockwork vein system. |
