The Elizabeth Mine was a copper mine located on the town line between the Town of Strafford and the Town of Thetford, in Orange County, Vermont.. The ore deposit was discovered in , but mining did not start until Open pit mining and from underground mining was conducted. The mine produced up to 8,, lbs. of copper () and was closed in Location: Strafford / Thetford, Orange County.

    ITRC – Ely Copper Mine Site, Orange County, Vermont August 2 Past mining operations at the site included cobbing, roasting, and smelting the ore. The ore mined at the site averaged % copper. The ore was fragmented, or cobbedto a product, containing approximately 7% copper. Ultimately, the ore was smelted to produce a copper matte. The abandoned Elizabeth Cu mine is near South Strafford in east-central Vermont in the Ompompanoosuc River watershed (43°49 ′ N; 72°19 ′ W) ().The mine is part of the Vermont Cu belt, which contains Besshi-type massive sulfide deposits hosted in locally calcareous siliciclastic sedimentary and basaltic rocks of Silurian to Early Devonian age (Slack, , Slack et al., Cited by:

    The Ely Copperfield Mine is near West Fairlee, Vermont. Historically the site has been part of the Orange County Copper Mining District. The Ely Copperfield Mine was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. Vermont copper belt. The Elizabeth and Ely mines worked Besshi-type massive sulfide deposits located in the Vermont copper belt in Orange County, Vermont. Bedrock includes metasedimentary and minor mafic metaigneous rock of Silurian and Early Devonian by:
