One of four small mines worked by the Lane family from the mid-19th century and famous for native bismuth. The other three mines are Lane’s Copper Mine (Fan Hill Road - also in Monroe) (http://www.mindat.org/loc-234050.html), Lanes' (Lead and Silver) Mine (Elm Street - also in Monroe) http://www.mindat.org/loc-14012.html, and Lane’s Mine of Trumbull (http://www.mindat.org/loc-23342.html).
Coffey (1974) states:
"'In October, 1849, Ephraim Lane leased from Arnold Hurd eight acres of land off Barn Hill Road across from the Gray-Hurd homestead (20 Barn Hill Rd.) for “the coal ores, fossils, minerals and rocks containing mineral substances…together with the right of digging, boring, blasting, mining and excavating.'
This mine was reopened in the 1890’s and was again in operation in the 1920’s. It most often was called Booth-Hurd’s Bismuth Mine. Bismuth was found to occur there in a free state in quantities, as was barylium [sic]."

|Devonian - Silurian|
358.9 - 443.8 Ma
|The Straits Schist (Goshen Formation of Massachusetts)|
Age: Paleozoic (358.9 - 443.8 Ma)
Description: Silvery to gray, non-rusty, coarse- to very coarse grained, generally poorly layered schist, composed of quartz, muscovite, biotite, oligoclase, garnet, and commonly with staurolite and kyanite or sillimanite; graphitic almost throughout. Distinctive sequence of metamorphic strata overlying the Collinsville Formation in the Bristol quad., is here correlated with the Straits Schist of Fritts (1963) in the Southington quad. Consists mainly of rusty-weathering, medium- to coarse-grained, commonly crenulated, garnet-bearing, graphitic, muscovite-rich, plagioclase-quartz schist with graded bedding. Unit is called The Straits Schist following the original usage of Rodgers and others (1959). In the southern part of the Bristol quad., unit includes the Southington Mountain Member (here reduced in rank) in its upper part. Age of The Straits is inferred to be Silurian or Devonian. Unit is tentatively correlated with the Goshen Formation based on lithologic similarities and a possible unconformity at the base (Simpson, 1990).
Comments: Part of Central Lowlands; Iapetus (Oceanic) Terrane - Connecticut Valley Synclinorium; Hartland Belt Secondary unit description per CT008.
