This report describes four digital data sets (presented as separate sheets in tables.xls, an Excel97-format file) used for this modeling: 1) training sites for epithermal gold, 2) placer gold sites, 3) training sites for carbonate-hosted lead-zinc, and 4) small lead-zinc mines. Purpose: This dataset was developed to provide mineral resource data for northeast Washington for use in future spatial analysis by a variety of users. This database is not meant to be used or displayed at any scale larger than 1:24,000 (e.g., 1:12,000 or 1:2,000). Supplemental_Information: The Excel97 file, of99-384.xls, contains five (5) sheets corresponding to the five tables listed in the Open-File Report 99-384 text. Table 1 in the text corresponds to the sheet titled 'Trainsites_epith' Table 2 in the text corresponds to the sheet titled 'Placer_gold_sites' Table 3 in the text corresponds to the sheet titled 'Trainsites_PbZn' Table 4 in the text corresponds to the sheet titled 'Small_PbZn_Mines' Table 5 in the text corresponds to the sheet titled 'Township_location' Time_Period_of_Content: Time_Period_Information: Single_Date/Time: Calendar_Date: 1998 Currentness_Reference: Date that original data was extracted from the USGS MRDS and MAS/MILS databases.

Any hardcopies utilizing these data sets shall clearly indicate their source. If the user has modified the data in any way they are obligated to describe the types of modifications they have performed on the hardcopy map/report. User specifically agrees not to misrepresent these data sets, nor to imply that changes they made were approved by the U.S. Geological Survey. Data_Set_Credit: David Boleneus compiled the data in digital format from the USGS MRDS and MAS/MILS databases. Compilation included removal of duplicate records, verifying latitude-longitude location and classifying sites as type of mineral deposit as described in the text. The accuracy of the data in the MRDS and MAS/MILS was relied upon as correct and was not field checked. Other sources were used to verify the correctness of the data to the extent possible.

Logical_Consistency_Report: Point data is given in latitude and longitude (decimal degrees). Completeness_Report: This digital dataset was produced from unpublished MRDS and MAS/MILS databases and is not considered to be a unique mineral resource dataset for the area. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The horizontal positional accuracy for the digital data was not checked. The point locations given by the MRDS and MAS/MILS databases were not modified and were compared to determine the most accurate location.

Source_Citation_Abbreviation: USGS MRDS Process_Step: Process_Description: The data was originally provided in two formats. The USGS MRDS was provided in an ACCESS database and was exported to EXCEL97 for purposes in this report 1998. The USBM MAS/MILS was provided in dBase format by Douglas Causey of USGS and was exported to EXCEL97 for purposes of this report in 1998. Spatial_Reference_Information: Horizontal_Coordinate_System_Definition: Geographic: Geographic_Coordinate_Units: Decimal degrees Entity_and_Attribute_Information: Overview_Description: Entity_and_Attribute_Overview: The data consists of five worksheets in the Excel97 file, "of99-384.xls". Definitions of attributes in Excel97 file, of99-384.xls: The following eight field names/items/column headers are common to Tables 1, 2, 3, 4, and 5: 1. No.-- Record number in table 2. Site name -- Name used in MRDS or MAS/MILS databases 3. MRDS ID NO. -- MRDS identifier number, 1st or 2nd digit are letters, followed by numbers 4. MAS ID NO.-- MAS identifier number, a 10-digit number 5. Latitude -- Latitude location of the site as cited in the database in decimal degrees. If the latitude was not cited, then it was calculated from the township, range and section using the Wefald script. 6. Longitude--Longitude location of the site as cited in the database in decimal degrees. If the longitue was not cited, then it was calculated from the township, range and section using the Wefald script. 7. County -- County in which site/deposit is located. 8. State -- State in which site/deposit is located. Other field names/items/column headers used in of99-384.xls: 9. Commodities present -- Elements/mineral commodities present 10. USGS Model -- Name and number of USGS mineral deposit-type model (Berger, 1992; Briskey, 1992; Mosier, Sato, Page, Singer, and Berger, 1992; Mosier, Singer, and Berger, 1992) 11. Production size -- Qualifier of quantity of ore produced 12. Development status -- Status of exploration or development at the site 13. District -- Mining district name 14. Tons produced -- Short tons of all historical ore produced (estimated from Derkey, Joseph and Lasmanis, 1990) 15. Township -- Township and direction (N=north) 16. Range -- Range and direction (E=east) 17. Section -- Section(s) 18. Table -- item in Table 5 indicating in which table (either Table 1, 2, 3, or 4) the site is described. Table 1. Training sites for epithermal gold model File name: of99-384.xls; sheet name: Trainsites_epith The training sites consist of a collection of sites (either mines, prospects or occurrences) selected from MRDS or MAS/MILS database because of their epithermal gold-like characteristics. Sites were qualified for the epithermal gold model if they met the selection criteria below for any of the USGS models for Au-Ag hot spring, 25a (Berger, 1992), Creede epithermal veins, 25b (Mosier et al., 1992), or Comstock epithermal veins, 25c (Mosier, Singer and Berger, 1992). Minimum selection criteria are a) Sites are spatially associated with Eocene volcanic or hypabyssal rocks and b) Sites contain gold in quartz veins or disseminations. Table 2. Placer gold sites File name: of99-384.xls; sheet name: Placer_gold_sites Placer gold sites -- Indicates locations of mines or prospects of placer gold exploration or development. Selection criteria for the 67 sites obtained from MRDS and MAS/MILS were a)"gold" is the primary commodity and b) "placer" was indicated by the name, deposit type, or modifier of commodity. See definition of attributes from Table 1. Table 3. Training sites for carbonate-hosted lead-zinc model File name: of99-384.xls; sheetname: Trainsites_PbZn The training sites consist of sites (mines, prospects or occurrences) selected from MRDS or MAS/MILS, because they exhibit characteristics of explored or developed carbonate-hosted lead-zinc deposits. Sites were qualified as carbonate-hosted lead-zinc deposits if they met the selection criteria below for the USGS model for carbonate-hosted lead-zinc deposits (Briskey, 1992). Minimum criteria by which the 11 mines were selected are a) lead and zinc are the primary commodities; b) the deposit is either strataform, pipe-like, or breccia in form or replacement in nature; c) the deposit occurs within strata of either the Maitlen Phyllite of Cambrian age, the Metaline Formation of Cambro-Ordovician age, or the Ledbetter Slate of Ordovician age; and d) the mine has produced more than 100,000 tons of ore. Table 4. Small lead-zinc mines and prospects File name: of99-384.xls; sheet name: Small_PbZn_Mines Smaller deposits described as carbonate-hosted lead-zinc deposits are those where no ore was produced or had total production up to 100,000 tons. These smaller deposits were selected using the selection criteria used for training sites of carbonate-hosted lead-zinc deposits (Briskey, 1992) with the exception that the deposits from this group were selected because they had no commercial production or produced 100,000 tons or less of ore. Table 5. Township and range location for sites File name: of99-384.xls; sheet name: Township_location The township-range-section and latitude-longitude locations in this table are taken from the databases. For those not available, the Wefald script was used to calculate from available data. Some sites were checked against those listed by the Washington Department of Natural Resources (Derkey, R.E., Joseph, N.L., and Lasmanis, R., 1990) Entity_and_Attribute_Detail_Citation: See Open-File Report 99-384 text, available on-line at http://wrgis.wr.usgs.gov/open-file/of99-384/ Distribution_Information: Distributor: Contact_Information: Contact_Organization_Primary: Contact_Organization: U.S. Geological Survey Information Services Contact_Address: Address_Type: mailing and physical address Address: Open-File Reports, Box 25286 City: Denver State_or_Province: CO Postal_Code: 80225 Country: USA Contact_Voice_Telephone: 1-303-202-4200 Distribution_Liability: The U.S. Geological Survey (USGS) provides these geographic data "as is."
