Iron formation in volcanic rocks.

"Goethite, pyrite, and siderite are the ore minerals of the Helen iron range in which these mines occur.

" The iron deposits north of Wawa lake were discovered during the Mihipicoten gold rush of the late 1890's. The first mine to come into production was the Helen Mine... in 1897... Goethite was the principal ore body until [it] exhausted in 1918. Attention then was directed to mining the siderite ore...[since] 1939 and has been continuous since that time.

" The company arranges conducted tours of the operation for groups such as schools... Requests should be made by writing to the company."
