Vladimirite is a rare calcium arsenate mineral with a formula of Ca5(HAsO4)2(AsO4)2·5H2O. It is named after the Vladimirovskoye deposit in Russia, where it was discovered in the 1950s.
The Michigan Smelter was a copper smelter located at Cole's Creek on the Keweenaw Waterway north-west of Houghton, Michigan near the old Atlantic mill. The smelter was created in 1903-4 as a joint effort between the Copper Range Company and Stanton group of mines. An Atlantic dam on the site was reused by the smelter as a water source. In 1905, the smelter broke a world record by casting 292,000 pounds of fine copper in seven hours with a single furnace and only ten men. The smelter operated through World War II and stopped all operations in 1948.
Paramelaconite is a rare, black-colored copper(I,II) oxide mineral with formula CuI
2CuII
2O3 (or Cu4O3). It was discovered in the Copper Queen Mine in Bisbee, Arizona, about 1890. It was described in 1892 and more fully in 1941. Its name is derived from the Greek word for "near" and the similar mineral melaconite, now known as tenorite.
Mohawkite is a rare rock consisting of mixtures of arsenic, silver, nickel, skutterudite and copper, with the formula Cu3As up to Cu6As, and the most desirable material was usually found in white quartz matrix. It has a hardness of 3–3.5 and a metallic luster. It is named after the Mohawk Mine, where it was originally found. Colors range from brassy-yellow to metallic gray, and sometimes will have a blue or greenish surface tarnish. These colors come from its two main ingredients, the arsenic-rich copper minerals algodonite and domeykite. Its color may resemble pyrrhotite, but unlike pyrrhotite, mohawkite is not magnetic.
The Mohawk Mining Company was a major copper mining company, based in the Keweenaw Peninsula of Michigan, that was established in November 1898 and lasted until 1932.

The Mohawk mine operated until 1932; in 1934 it was purchased by the Copper Range Company.
