About this file
The file contains two technical figures illustrating the structure and relationships of a mine waste database for the Earth Mapping Resources Initiative (Earth MRI). Figure 1 is an entity relationship diagram showing the database schema, which includes tables for Points, Polygons, Resources, Geology, and References, with interconnected fields such as Site ID, Feature Name, Location Description, and Calculated Volume. Figure 2 is a schematic illustration demonstrating the relationships between a mining site and its various features, including an adit, mine dump, open pit, ore stockpile, and tailings (undifferentiated and pond).
These figures are part of the technical documentation for the Earth MRI Mine Waste Cooperative Agreements FY2025, a federal grant opportunity from the USGS Mineral Resources Program. The program will allocate approximately $5 million through competitive proposals to state geological surveys for mine waste inventory, characterization, data compilation, sampling, and mapping activities. The cooperative agreements must be obligated by September 30, 2025, and support the broader Earth MRI goals of advancing geological mapping and critical mineral resource identification across the United States.

Figure 1. Entity relation diagram showing the structure of the mine waste database.
Figure 2. Schematic illustration, not to any scale, showing the relationships between a site and mine features. The site is the cluster of features. As drawn, the site contains six features: one adit, one mine dump, one open pit, one ore stockpile, one tailings – undifferentiated, and one tailings – pond. Only the four mine waste features (i.e., one mine dump, one ore stockpile, one tailings – undifferentiated, and one tailings – pond) would be entered into the mine waste database. Each of those features would have their own point and polygon feature class records, as well as their associated records in the reference and resources tables. If the geology in the open pit and underground workings is similar, the geology records can be populated at the site level, and only one record is needed that documents the geology for all four mine waste features.
