STUDY AUTHORS: Knight Piésold

Surficial and bedrock geology, geological structure, deposit types, alteration and mineralization based on previous studies, exploration drilling programs, test pits, and aerial photographs are discussed. This information is important to understanding the mining potential and structural stability of the area. Geology and mineralization may also affect water quality, hydrology, and soils.

Elements

  • Crews at Pebble have drilled nearly 1 million feet of core, or more than 189 miles, with some holes as deep as 5,000 feet.
