Rogers Mine, Huntingdon Township, Madoc Area, Hastings Co., Ontario, Canada
In vein in dolomitic marble.
"The deposit was discovered in 1909 by Donald Henderson and Chesley Pitt of Madoc. Between 1910 and 1914 it was mined from an open pit. In 1914 a shaft was sunk but the mine remained inactive unti 1943 when Reliance Fluorspar Mining Syndicate Limited took over operations until 1951. This was the mine's most productive period and four shafts (37.5, 26.5, 36.5, and 73 m deep) were sunk. Some 39,000 t of ore were produced during this period making this the leading fluorite producer in the Madoc area. Some of the old buildings remain on the site. There are large dumps near the shafts."
This mine is the source of the wonderful "Madoc" fluorites. Specimens are typically pale sea green optical quality fluorite crystals of cubic habit with minor octahedral faces. Many were recovered on a white to tan fine grained barite matrix. The Town of Madoc is nearby in Madoc Township. Many specimens were recovered during surface excavations in the early to mid 1970s. All mines in the area have since been recovered and are now inaccessable.
