The mining claim density data of federal lands in Oregon are combined with the digital Oregon Public Land Survey (PLS) to create a digital map of the density of mine claims in Open-File Report 99-541. The mining claim density data of federal lands in Oregon was one of 13 western states released in Open-File Report 99-325. The database for Oregon was converted to an Arc/Info file and connected with the PLS by an Arc/Info relate. As stated in OF 99-325, "These mining claim density databases were created from data obtained in March 1997, from the Mining Claim Recordation System (MCRS) of the Bureau of Land Management. These databases provide mining claim density information in a tabular form. They quantify the status...

Unpublished mineral assessment reports of the Colville andOkanogan national forests (Chelan, Ferry, Okanogan, PendOreille, Skagit, Stevens, and Whatcom counties, WA) containdata on 3,934 samples analyzed for gold, silver, copper, lead,zinc, molybdenum, tungsten and uranium. Data presented herewere obtained by R.A. Grant (1982a,b) for an assessment ofthe mineral potential of these national forests during1979-1982 under a contract from the USDA-Forest Service.

Permits to explore for and (or) develop mineral resources onFederal lands can be used to indicate locations and types ofmineral-related activities on national forests. Permits for theseactivities require filing of a Notice of Intent to conduct mineralexploration activities and (or) a Plan of Operation, ifsignificant land disturbance results. This compilation of noticesand plans for the Colville, Kaniksu, Okanogan, and Wenatcheenational forests between 1967 and 1998 is intended for use incombination with geologic and economic information to predictfuture mineral-related activities in the region.

This report provides background information on the regionalgeochemical data provided by the US Geological Survey to the USForest Service and Bureau of Land Management Interior ColumbiaBasin Ecosystem Management Project (ICBEMP). This report is one ina series of digital maps, data files, and reports generated by theUS Geological Survey to provide geologic process and mineralresource information to the Interior Columbia Basin EcosytemManagement Project. The various digital maps and data files arebeing used in a GIS-based ecosystem assessment including ananalysis of diverse questions relating to past, present, and futureconditions within the general area of the Columbia River Basin eastof the Cascade Mountains.
This metadata describes a series of coverages that were developedby the authors as a result of reviewing all available data anddrawing boundaries that they thought included areas that mightcontain selected deposit types. (The deposit types include bothsome from the Cox and Singer classification system and somedescriptive types that have not been formally described.) Thedeposit types are:>coal (lignite),>hot springs gold-silver,>gold-silver mixed metal veins,>distal disseminated gold-silver,>antimony veins,>tungsten veins,>low-sulfide gold-quartz veins,>polymetallic layers and veins,>copper-silver polymetallic veins,>manganese layers and veins,>barite layers and veins,>porphyry copper-molybdenum,>copper skarn,>iron...

The area of this data set includes the classic geology and mineral deposits of the Keweenaw Peninsula, renowned for the occurrence of great volumes of Middle Proterozoic flood basalts and the world's largest concentration of native copper. Native copper was mined there continuously from the 1840's to the 1960's. For the earlier part of that period the Keweenawan native copper district was the principal source of copper for the United States.

Most information was obtained from MRDS (U. S. Geological SurveyMineral Resource Data System). The data was put into GSMODS (a USGSdesigned database). The data was modified by field examination by theauthors. An arc output was generated from GSMODS and a point coveragewas created.

Digital mineral databases are necessary to carry outweights-of-evidence modeling of mineral resources forepithermal gold and carbonate-hosted lead-zinc deposits innortheast Washington. This report describes four digitaldata sets (presented as separate sheets in tables.xls, anExcel97-format file) used for this modeling: 1) trainingsites for epithermal gold, 2) placer gold sites, 3) trainingsites for carbonate-hosted lead-zinc, and 4) small lead-zincmines.
