The term COMSTOCK LOAD refers to a type of ORE deposit found in Nevada. It is composed of an ORE (3 letters), a LODE (4 letters) and an ADIT (4 letters). The ORE is typically silver or gold, and the LODE is a vein of ORE running through the rock. The ADIT is an entrance to the mine, usually dug into the side of a mountain. The Comstock Load was discovered in Nevada in the mid-1800s and was one of the most productive silver and gold mines in the United States.
