Chinn Mine is an abandoned calcite mine turned tourist attraction, restaurant, and gasoline station located across the mouth of Shawnee Run along the Kentucky River in Brooklyn, Kentucky.
The mine was part of the Central Kentucky Mineral District consists of more than 200 vertically dipping vein deposits, including barite, calcite, fluorite, galena, and sphalerite. 3 Mining along the Kentucky River began circa 1900, with significant mines operating at Mundys Landing, Gratz and elsewhere.
The Chinn Mine was begun by Colonel Jack Chinn of the Chinn Mining Company and consisted of a nearly vertical fissure vein approximately six- to 16-feet-wide that was traceable for at least one mile to the south. 5 6 7 A mill was built on the river at the mouth of the mine, which had a capacity of 60 tons of calcite per day. Ccryptograined limestone, 2 baryte, fluorite and sphalerite was also discovered within the fissure. 5 6 7 The mill pulverised calcite which was then shipped to High Bridge on a barge where it was loaded into railroad cars along the Cincinnati Southern. 1
Chinn also operated at nearby Mundy’s Landing. 1 Mining in the area ceased not long after World War I concluded. 3
After the Chinn Mine was abandoned, it became home to Chinn’s Cave House, a tourist attraction, restaurant, and gasoline station along US 68. 4 It was operated by Col. George M. Chinn, a graduate of the Millersburg Military Institute and Centre College. Chinn became a Colonel in the United States Marine Corps and a co-inventor of the Mark 19 40mm automatic grenade launcher.
