Description:
“Index of Mining Properties in Pima County, Arizona”
is the second of the planned series covering the counties
of the State. The first, on Cochise County, was published
in 1973 as Arizona Bureau of Mines Bulletin 187. The total
mineral output from Arizona for over one hundred years
has come from many mines, ranging from major operations
to small mines and prospects. The record of those opera
tions are scattered in numerous publications of Federal and
State agencies, in articles in various technical journals,
in public and private reports, and in newspaper clippings.
Many such sources are not readily available to persons
seeking such information. Thus these indices are designed
to provide, in a concise form, as much information on min
ing properties as may be found.
No attempt has been made to name and describe every
mining property that may have been located. The selection
has been made by the compiler on the basis of production
records, special geologic or mineralogic character, or
importance in relation to known or possibly hidden mineral
resources. The identification of areas of high probability
for mineral that might become economic to mine is impor
tant not only from the standpoint of a future national re
source but also in planning the best use for the land involved.
