The validity of this locality and/or its minerals is very questionable. An early reference to it is by Hitchcock (1823), essentially quoting Cleaveland (1822), where he writes:
104. Native Antimony. At Harwinton, Litchfield County, in broad plates. (Silliman.)
105. Sulphuret of Antimony. At Harwinton.* (Silliman.)
* 104 and 105 need confirmation - Editor.
105. Sulphuret of Antimony. At Harwinton.* (Silliman.)
* 104 and 105 need confirmation - Editor.
The editor at that time was Benjamin Silliman. Apparently he never confirmed it as a search for "Harwinton" in all the 19th century AJS did not reveal any additional references to the town.
Robinson (1825) and Januzzi (1976) offer no new information and merely parrot some variation of the language in Hitchcock (1823). The locality is conspicuously absent in every major early reference on Connecticut mineralogy including the very comprehensive Shepard (1837). Considering the many 19th century American Journal of Science articles written about mineral finds from tiny places in Connecticut, such as the various "Lane's Mines", the absence of any more about this locality is telling. Chipman (1860), alluding to the descriptions of "blocks of massive size", implies that it sounds too extreme to be true. The Yale Peabody Museum on-line mineral collection catalog contains no antimony or stibnite from Connecticut.
Schooner (1961) writes that the locality was the "old lead mine", which lent its name to a brook in town, but this is not borne out by the original references. He states that these minerals were "apparently never substantiated". Many old "lead" mines turned out to be actually "black lead" or graphite and the rocks in the area are graphite rich. Another strong possibility is ilmenite, which is common in western Connecticut and was not described until 1827.
The exact locality is unknown. Coordinates are for the intersection of state Route 4 and North/South Roads at the center of town.
