It was derived and extensively updated from a previous release by McFaul and others, 2000. The original and unedited dataset is CO_MAS.xls. Only fields that are commonly populated and therefore may be of interest in analyzing mineral trends are included in this file; for instance, comment fields are not included in the GIS dataset. Purpose: To spatially show locations and relationships between known mineral occurrences in Colorado. Supplemental_Information: This dataset was excerpted from the McFaul and others, 2000 data release for North America. The data were intially compiled by or for the former U.S. Bureau of Mines over a span of many years. Few updates have been made to the Colorado data in about 10 years. Upon the closure of the USBM in 1996, custody of the database was transferred to the USGS.

This digital map is not to be construed as a legal representation of any locality, nor is the data within any field considered reliable. In most cases, the data should not be used at scales larger than 1:500,000, although many localities are accurately located certainly at 1:24,000 scale. It is not possible to determine the accuracy from the database and any field suggesting that the accuracy is known, is unreliable. Any hardcopies utilizing this data set shall clearly indicate this source. If the user has modified the data in any way, (s)he is obligated to describe the types of modifications performed on the hardcopy map. User specifically agrees not to misrepresent this dataset, nor imply that changes were approved by the USGS.

In hundreds of cases, the mine may belong in a different county, quadrangle, or even state, from where its latitude and longitude locate it. In dozens of cases, the county code is clearly erroneous. In general, the location data are accurate at 1:500,000, though in many cases locations are accurate at 1:24,000. The accuracy can not be determined from this database. Completeness_Report: Only mines and prospects that have been recorded by the former USBM or were included in former databases are included. In many cases, the data have not been revised in many years. Most mineral localities discovered or documented in the last dozen or so years are completely missing.

Queries of the data against other spatial data layers confirmed many of the numerous errors and pointed out others. Comparison with other local datasets (i.e. Wilson and LaRock, 1992, for Summit County, and Wilson and others, 2001, for Gunnison, Uncompahgre, and Grand Mesa National Forests) pointed out several hundred more problems. Each of the records in the McFaul and others, 2000 dataset has been retained or, if deleted (either because it is unverifiable or duplicates another record) it has been given to those who maintain the master MAS/MILS database, if it is ever updated.

Overview_Description: Entity_and_Attribute_Overview: Most of the above fields were directly imported from an as yet unreleased revision to the master MAS/MILS database released by McFaul and others, 2000. Dozens of fields for hundreds of records were revised for the CO_MAS file in this report although the original data are in the .xls database included in this report. LAT and LONG are not accurate. The grossest errors have been changed to make the locality reasonable but not accurate. QUAD24K, QUAD100K, and QUAD250K have all been extensively revised. GEOLSURVEY was filled in if the lead author could reasonably ascertain that a record in the CO_MAS file directly corresponded to a CO_MRDS record. Entity_and_Attribute_Detail_Citation: Anna B.
