To make informed decisions about
Economic impacts
Resource development and management
Impacts on water supplies
Impacts on land use
Environmental impacts (including potential sources of AD [acid drainage] or other MIW [mine influenced waters])
Physical hazard assessment and remediation
Adit, Jicarilla Mountains, Lincoln County

FUNDING SOURCES NMBGMR
NM State Land Office (Mineral Resource Assessment of Luna County, NMBGMR OF-459)
EPA (Uranium database, NMBGMR OF-461)
ACofE (Mines database of Sierra and Otero Counties, USGS OF)

AVAILABLE DATA
The New Mexico Bureau of Geology and Mineral Resources (NMBGMR) has been collecting data on mining districts since it was created in 1927
The task is to convert these data into electronic form and import into ArcGIS
-
Databases Coal fields and Mining districts
Coal mines and reserve data
Mines and mills
Geochemistry
Photographs (both recent and historic)
Bibliography
Mine maps
Mine production
Mine reserves
Drill data (Petroleum records)
Well logs (Coal library and Petroleum records)
-
Coal Fields and Mining Districts 273 coal fields and mining districts
in NM ~30 districts have had zero
production
Each district is classified by predominant commodity
Each district can have more than 1 commodity type
28 coal fields
40 industrial minerals districts
173 metals districts
32 uranium districts
Chino copper mine
San Juan coal mine
-
Coal mines,Raton Basin, Colfax County
-
Mines and Mills Data
Organize, catalog and scan the mining archives
Create a database of mines in New Mexico based on the NM Mine File Catalog (>16,000 mines) with links to more detailed location by section, township range files (>6000 file cards)
More than 2000 mine plats scanned and cataloged
Scan and catalog thousands of reports, both published and unpublished, accompanying mine maps, newspaper articles, assay reports, and historical mine photographs

Mining Archives
-
New Mexico Mines DatabaseRelational database in ACCESS that will
ultimately be put on line with GIS capabilities
ACCESS is commercial software and this design is compatible with other formats
Metadata (supporting definitions of specific fields) can be inserted into the database
ACCESS is flexible and data can be easily added to the design
Easily imported into ArcGIS
-
The term mine is defined here as any mine, prospect,
mineralized outcrop, altered area, mill, smelter, or other
mining-related facility, including mineral wells, but excluding geothermal wells,
petroleum wells.
-
Mine_id in some cases refers to one mine feature (adit, pit, shaft,
etc.) and in other cases to several mine features. If a mine
occurs in 2 quadrangles or 2 counties, then it receives 2 separate Mine_id numbers.
Large mines receive one Mine_idand as many mine_feature id
numbers as needed.
-
Mines Each mine is classified by
predominant commodity
Each mine can have more than 1 commodity type
8200 mines in the database that include active, inactive, abandoned, and exploration sites
Not all mines have workings
Some mines have multiple workings
Questa mine, Taos County
-
Industrial Minerals
Any rock, mineral, or other naturally occurring material of economic value, excluding metals, energy minerals, and gemstones
One of the nonmetallics
Includes aggregates
White Mesa gypsum mine
M.I.C.A. mica mine (closed)
-

UNRESOLVED ISSUES
How to provide the data to the public
Some mines are not in districts
How to combine databases from different states, federal agencies, etc.
How to include mine maps, mine plans in the database
How to maintain quality control of the data
How to continue funding this effort
