Copper mine working a Besshi-type massive sulfide deposit.
Located on "Copperas Hill". First opened in 1793. Ore is pyrrhotite containing disseminated chalcopyrite. Mined for copper beginning in 1830. Closed in the Great Depression, re-opened then closed in 1958. In 1918 the mine produced 300,000 lbs. of copper and 35 oz. of silver (Weed, 1920).

According to the Town of Strafford website: The discovery of copperas and copper ore at Strafford in the 1790s led to the creation of the Elizabeth Mine Company and the Vermont Mineral Company. During the last period of its operation the Elizabeth Mine was the largest in New England... President James Monroe’s 1817 visit to Strafford’s copperas works caused a sensation locally.

Chronology (Source: HISTORIC AMERICAN ENGINEERING RECORD, National Park Service, VT-35, undated, available at Library of Congress online (link below):

1793 - Metallic sulfide ore deposit discovered on Copperas Hill
1809 - Vermont Mineral Factory Company begins surface mining and copperas (iron sulfate) production
1817 - U.S. President James Monroe visits mine on goodwill tour 1830 Underground mining begins; Isaac Tyson, Jr. smelts first copper at Furnace Flat
1854 - Intermittent copper smelting at Furnace Flat through 1867
1882 - Copperas production ends; James Tyson names mine “Elizabeth” after his wife; Tysons smelt copper at Sargent Brook to 1890
1898 - Tysons construct 1898 Adit; smelt copper on east side of Copperas Hill through 1902
1906 - Mine purchased by August Heckscher; new smelters installed but operate intermittently
1916 - First froth flotation ore milling at Elizabeth Mine 1925 American Metals Company briefly operates mine
1928 - National Copper Corporation and Frederick Foote briefly operate mine 1942 - Vermont Copper Company, Inc. organized, begins construction and reopens mine for World War II copper production
1943 - First copper concentrate shipped from Elizabeth Mine mill for smelting by Phelps Dodge Corporation at Laurel Hill, Long Island, New York
1948 - New adit and shaft dug to develop ore down to 975 foot level 1949 New crusher and equipment added for extra capacity; ore extraction begins from waste dumps, South Open Cut, and Ely Mine dumps 1950 Copper production reaches 7 million lb. 1952 Pyrrhotite extraction for sulfur for Brown Paper Company of Berlin, New Hampshire begins; Tailings Pile 2 started
1954 - Copper production exceeds 8.5 million lb.; Appalachian Sulphides, Inc. purchases Elizabeth Mine from Vermont Copper Company
1958 - Ore exhausted as mining progresses north of Ompompanoosuc River; Appalachian Sulphides closes Elizabeth Mine and shifts operations to historic Ore Knob, North Carolina copper mine

UPDATES:
2001 - EPA placed the site on the National Priorities List (NPL) in June
2003 - EPA begins cleanup of mine site, designated a Superfund site
2010 - $8 million stimulus grant jump-started cleanup efforts
