Mining and Quarrying in Maine
- Our virtual tour is a series of photos which portray some of the history and types of Maine mining and quarrying.
- Metallic Mineral Deposits of Maine (map)
- Known occurrences of metallic minerals shown on a generalized geologic map of Maine. Locations of ten "significant" deposits also shown. For more information, see Maine's Mineral Resources database.
- Maine's Mineral Resources (database and interactive map)
- Comprehensive information about metallic and non-metallic mineral resources compiled for sites in Maine, including occurrences, showings, prospects, significant deposits, and historical mines available in an interactive map and as a CSV file for download. Includes town, reported commodities, site characteristics, and source information for each locality.
- Core Repository and Mineral Exploration Data
- The Maine Geological Survey maintains a repository of rock core obtained by diamond drilling for mineral exploration projects over many years. In addition to the physical rock core that have been donated to the Maine Survey, there are associated paper records, which include such things as maps of drill core locations, technical logs of drill core, and a limited amount of geochemical and geophysical information and geologic reports.
- Maine Mining Claims (map)
- Historical mining claims locations and links to supporting Maine Mining Bureau claim maps and exploration files. These data were compiled with the assistance of a USGS Digital Data Preservation grant in 2021.
