This locality is a combination of two different mines that overlap, the George W. MacLeod Mine [https://www.mindat.org/loc-11346.html] and the Helen Mine. Unless you know exactly which of these two mines your sample came from, this is the place to put it.
A calcite crystals specimen on matrix is said to come from this locality (according to the label of the dealer, D. Weinrich).

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 Michipicoten gold rush of the late 1890s. 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."
Iron mines in the Wawa area [from http://www.wawa.cc/living-in-wawa/about-wawa/history/ - Link dead October 2019]
"Gold mining led to the coincidental discovery of high-quality iron ore in the area. Francis Hector Clergue and his newly formed Lake Superior Power Company began mining operations at Helen Mine and, from 1900-1918 Helen Mine was the largest producer of Iron Ore in Canada.
The Helen Mine remained an open pit operation until 1950 and in 1960 the George W. MacLeod Mine went into production next to the Helen Mine. Throughout the nineties, Algoma Ore continued to be challenged by international markets and in December of 1997, Algoma Steel announced that they could no longer support the high cost of extracting low-grade iron from Algoma Ore. Even though Wawa’s mountain of iron ore still had more to give, operations were shut down in June of 1998, 100 years after iron was first discovered in this remote corner of Northern Algoma."
