Arimetco, Inc. was a mining company with properties in Arizona and Nevada. The collection contains economic geologic information on a limited number of properties, notably the Zonia Mine, Yavapai County, and the Courtland-Gleeson Project in Cochise County. The collection consists of geologic reports, maps, assays, drill logs and related materials.

This collection consists of economic geologic information on Anderson Mine and Date Creek area collected from the late 1960s to the late 1970s. It contains geologic reports, maps, assays, drill logs and related materials.

Sixty-three folders in this collection contain geologic, topographic and subsurface maps of Arizona. There are a number on the Yavapai County area, in particular the Yaeger Mine and Victor-Montezuma (AKA Hull Property and Montezuma & Huron).

Mason Coggin was director of Arizona Department of Mines and Mineral Resources during the mid 1990s. These images were either shot by or collected by him. The newest photo showing a date is from 1953, but some photos were clearly taken as late as the 1970s or 1980s. Perhaps better than any other photo collection from ADMMR, this collection focuses on miners, mines, machinery and buildings. There are several images of the Bisbee and Ajo areas.

These photographs were mostly taken from the ADMMR Mining collection, records on mineral resource exploration and mining in Arizona from late 1800s to the early 2000s. Photographs principally relate to a mineral locality reported in the Arizona Mineral Industry Location System. Photographs titled "ADMMR" document the history of the Arizona Department of Mines and Mineral Resources, making up a little over 10 percent of the collection. Items were arranged alphabetically by prints and negatives, then slides and lastly Polaroids. The hyphenated number at the end of each title refers to the old numbering system employed by our dedicated volunteers and should not be confused with a mine's name.

The Arizona Geological Survey (AZGS) achieved its annual goals of inventorying the mining records previously held by the Arizona Department of Mines and Mineral Resources. Twenty-eight out of 31 collections of mining records are inventoried and will have finding aids available online at the AZGS repository by mid-August. Seven of these inventories are currently available via the AZGS Document Repository as of July 11, 2012, http://repository.azgs.az.gov/collection/1322. A librarian was hired to direct and coordinate this project in October 2011. Since then a number of cataloging efficiencies for the project have been implemented. Microsoft Access was chosen as the database to better control typographical errors and reduce data entry redundancy. This database is in use to create inventories of all the collections. Once fully completed, the inventories can be built upon to create geographic metadata for each item. Development of full geographic metadata for 10,000 records is targeted for Fiscal Year 2013. The initial inventory of ADMMR collections identified by AZGS includes:  23 Special Collections containing approximately 13,500 folders, with 836,553 pages of records  6 Photo Collections containing approximately 7,400 images  1 Theses Collection with 371 papers  1 Map Collection containing approximately 10,000 maps A state vendor specializing in comprehensive document management systems and file scanning services was retained to assist with the scanning and digitizing of mining records. The estimate to scan each report, photo, slide, and map in the mining records totaled $185,455. This past year, AZGS contracted with state vendor OSAM Inc. to scan the ADMMR Map Collection of approximately 10,000 maps. It should be noted that the OSAM work only includes scanning and does not include the metadata creation or cataloging of the files; this work remains the primary focus of the AZGS in FY13.

This collection of photos shows the Richinbar mine in the 1930s and a revisit to the mine in 1957 by the Wheeler family. Carlton Wheeler graduated from the University of Oklahoma after WWI and worked as a geologist in Texas before moving his family to Arizona and working for the Richinbar mine. Most of the photos were taken in '33, '34, and '35. The Richinbar mine stopped operations in 1937.

Edwin Noel Pennebaker received a B.S. in economic geology from University of California in 1924 and later went on to graduate studies. From the mid 1920s until the mid 1980s, he worked mainly as a consulting geologist for numerous companies around the globe. During the period 1935 to 1976, he consulted for a number of companies in Arizona. After 1985, he was Director Emeritus of Coeur d'Alene Mines Corporation, Wallace, ID. This collection of economic geologic reports focuses predominantly on Arizona.
