Adams Mine

Posted on: Mon, 02/03/2020 - 08:00 By: Mike

Opened in 1963 and closed in 1990, this iron mine stretched over 4,000 acres of land, and featured six open pits. The deepest of these pits was 600 ft. The largest pit was almost a mile in length.

This site was also the centre of heated debate when it was suggested that Toronto send its garbage as landfill in these excavated pits. Plans for this were already being drawn up as early as 1989, before the mine had even closed.

Osceola Mine 13

Copper mining began on this site as early as 1873.

On September 7, 1895, a fire broke out on the 27th level of Shaft 3 and was intensified by the timbers used to support the mine. At the time, over 200 people were underground. Of those, 30 people were killed, including 4 boys. All of them appeared to have died of smoke inhalation, and all bodies were eventually recovered.

Quincy Stamp Mill

The original stamp mill was located close to Houghton, on Portage Lake. Runoff silt from the mill went into the lake, however, and threatened navigation in this important channel. The government threatened heavy fines and so the mill was moved.

An underground copper mine consisting of 7 incline shafts near the community of Centennial, just north of Calumet.

The Schoolcraft Mining Co. was organized in 1863 and worked the Calumet Conglomerate in a small scale operation until it went bankrupt in 1873.

Quincy Mine

The Quincy Mining Company was formed in 1846 as the result of a clerical error. During the great mining rush of the area, the same piece of land was inadvertently sold to two different parties. After discussions between the directors of the two interests, it was decided they should merge their interests and proceed.

Silver was first discovered in this area in 1908. Very shortly afterwards, this mine began operation. It is not known what quantities were produced during this phase of its operation, but it is known that it produced substantial quantities of both silver and cobalt.

Capitol Mine

I first saw this location late last year, but I was in search of a head-frame as listed in the AMIS database. Instead, at the coordinates listed, I found only a clearing made by the lumber company working this area. I went back this spring to have a closer look around and started with the old mill.

I decided that, rickety as it looked, I should climb the remains of the mill to get a closer look at what might remain inside. It was a slow, careful climb, but definitely worthwhile.

Geneva Lake Mine

My best information to date indicates that exploration began here in 1927. During the winter of 1929-30, equipment was being brought in by horse and sleigh. By 1933, a mine and several support buildings had been constructed to produce primarily zinc, but initial production was very low due to the market situation.

Bristol Mine

Iron Mining began in this Quebec community as early as 1872. This specific open-pit operation began in 1956, under Hilton Mines. It featured one of the first ore-pelletizing plants in Canada. Production apparently ended, for the most part, in 1976.
