The purpose of this report is to summarize the progress in use of digital image analysis techniques in developing a conceptual model for assessing porphyry copper mineral potential. The study area consists of approximately the southern one-half of the 1? by 3? Nabesna quadrangle in east-central Alaska. The digital geologic data base consists of data compiled under the Alaskan Mineral Resource.

The Copper Mountain (Morenci) mining district is located approximately miles northeast of Tucson, Arizona (Figure 1). It lies along the southern boundary of the Transitional physiographic province, a rugged mountainous region that separates the Colorado Plateau from the Basin and Range province.
Copper, its occurrence, and use. What is copper. Copper is a chemical element in the periodic table with the symbol Cu (from the Latin word cuprum, meaning ‘metal of Cyprus,’ where it was mined during the Roman era).Copper has an atomic number of 29 and atomic weight of grams per mole.
It is an element in Group 11 of the periodic table, sharing many properties with silver and gold. The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the introduction of steam shovels, the construction of railroads, and a surge in market demand near the start of the 20th century.
Some mines exploit porphyry deposits that contain sufficient gold or molybdenum, but little or no copper. ic / comparative porphyry copper mining and processing costs – alaska and arizona, pb, $ 20 ic / the mine map repository – a source of mine map data, pb, $ 2 ic / methane emission from u.

Copper mining has been a major industry in the United States since the rise of the northern Michigan copper district in the s. Indomestic mine production in the United States was valued.
Porphyry copper deposits result from the complex interactions and feedbacks of many processes. Owing to the complexity, a succinct definition that includes the essential attributes of this deposit class is elusive.
Consequently, this descriptive model uses a working definition of a porphyry copper deposit. The mining industry is vital to the Australian economy, accounting for around 32% of annual exports.
