Mother Lode: Gold deposits are generally classified as lode, placer, massive, or disseminated types.Gold lode deposits are almost always associated with acidic igneous intrusives in rocks of the Precambrian to late Tertiary periods.
Lode or Vein Mining. Conventional mining techniques are used in mining lode or vein deposits. The method chosen for a given gold area depends on the form and nature of the deposit; however, it almost always involves the sinking of a shaft to follow the deposit.
