Mineralization within the New York Canyon property consists principally of contact metasomatic copper skarn deposits, porphyry-type copper-molybdenum mineralization, and a combination or transition of these two types of mineralization. The property's copper skarns may be almost entirely oxidized, as at Longshot Ridge, or consist of both oxide and sulphide skarns as at the Champion prospect, located midway between the Longshot Ridge and Copper Queen prospects. At Copper Queen, the mineralization consists of copper sulphide skarn and porphyry copper-molybdenum sulphide.
Contact metasomatic skarn (also known as tactite) typically occurs in carbonate sedimentary rocks adjacent to small to moderate sized intrusive rock bodies of intermediate composition, such as monzonite and granodiorite. Heat and fluids from the intrusion recrystallize and alter the carbonate rocks, converting limestone and limy sediments to higher temperature calc-silicate minerals such as garnet, epidote, diopside, tremolite and calcite (Lindgren, 1913; Titley, 1995). A variety of metalliferous deposits can be formed, including those that are copper-rich, iron-rich or tungsten-rich.
