The Blue Diggings mine tapped into the Blue Diggings vein via major shafts including the Fairview, Blue Diggings and Last Chance shafts. The deepest was the Fairview shaft at 800 feet. Drifts and stoping were carried out extensively alng the vein.
The Blue Diggings vein lies 900 feet west of a generally parallel to the Rosiclare vein. Unlike most veins in the district, this one dips 65 degrees eastward. It is rather narrow, averaging less than 3 feet in width, with occasional swells to 8 feet. Significant fluorite deposits were found at depths of nearly 750 feet. Major drifts were made at the 300, 400, 500, 650 and 750-foot levels. The 800-foot level was for the most part barren of fluorite. The deeper levels of ore were found in the 1940's by extensive diamond drilling. [A. Goldstein, Min. Rec. 27:1, 1997, p. 7.]
