Information leading to the delineation of this focus area

Basis for focus area	Lithocap alunite, Cu-Mo porphyry, Cu skarn, and replacement and vein deposits inside a 10 km buffer around the Resolution porphyry Cu-Mo-Au deposit (33.2933, -111.0568). Area encompasses the Superior East, Magma, Belmont deposits, and a few historical Mn producers.
Identified resources	Indicated resources for copper and molybdenum. Historical production of manganese.
Production	Copper, Au, and Ag as well as over 30,000 tons of ~ 29% Mn were produced from the Monarch Vein (Queen Creek) (Farnham and others, 1961). The Superior (Magma) mine was active until 1996, producing more than 23 Mt Cu with an average grade of 5% Cu, as well as small amounts of Mn.
Status	Past mining, active project advancement for the Resolution deposit.
Estimated resources	Preliminarily reports for the Resolution porphyry Cu deposit indicate a 1.25 to 1.75 billion ton deposit grading 1.25% to 1.75% Cu plus Mo. A ~ 400 m thick by ~1200 m wide zone of advanced argillic alteration containing alunite straddles the 1% Cu shell.
Geologic maps	Horton and others (2017), scale 1:500,000; Richard (2010), scale 1:100,000.
