The Copper Flat porphyry copper deposit in the northern part of the Hillsboro district was discovered in 1975 (Castellano et al., 1977; Dunn, 1982, 1984), although alteration and mineralization in the area suggested to earlier geologists that a porphyry copper deposit should occur in .
Porphyry copper deposits associated with calcalkaline hostrocks are described in mineral deposit profile L04. EXPLORATION GUIDES GEOCHEMICAL SIGNATURE : Alkalic cupriferous systems do not contain economically recoverable Mo (< 100 ppm) but do contain elevated Au (> g/t) and Ag (>2 g/t).

Exploration History of the Resolution Copper Deposit, Pinal County, Arizona. ... Although evidence for a porphyry copper target had been recognized in the area under the volcanic plateau northeast of the Belmont mine as early as 1972, Magma Copper confined its exploration efforts over the next decade to the search for additional vein and ...
Exotic copper deposits, ferricretes, and manganocretes in Middle Tertiary through Holocene, alluvial sedimentary rocks are known to relate spatially to Sonoran porphyry copper deposits, but the nature of that relationship, especially for ferricretes and manganocretes, is poorly understood.

Porphyry copper deposits commonly yield molybdenum and silver as coproducts, were. The intrusive activity responsible for Arizona's porphyry copper deposits occurred about 70 million years ago, in the Earth's crust deep below the ground surface. The rich metal deposits were subsequently exposed millions of years later by faulting and erosion.
