Abandoned Ontario Mine – Croft Mine

My purpose for visiting the Croft Mine had been was to photograph the fabled head frame – Ralph Schroetter, my guide at Coe Hill had said that it was one of the last such relics in the area. I soon came to realize that finding the abandoned structure would be no easy task. The forest was so thick that I could barely see twenty feet ahead.

I attempted to piece together the most likely location for a mining structure from the location of the dumps, adit, and the many overgrown tracks. Along one old bramble covered path I found a shelf system that had held the drill cores, along another track I found a collection of rusty old barrels. I spent some brief amount of time on the dumps looking for traces of the garnet bearing pegmatite. Mysterious, moss-covered beams were strewn everywhere. Might one of these heaps be the head frame that Ralph had spoken of?

Climbing the hill above the adit, I hoped to sight my goal, but I soon realized that I was out of luck. A yellow carpet stretched off bewilderingly in every direction. Breaking through the canopy was impossible. It was like I was drowning in an endless rain of sticky wet leaves. If it were not for the contour of the hillside, a factor that helped maintain my orientation, I doubt that I would have found my way back to the access track.

The water in the adit was knee-deep and crystal clear. I could see corrugations in the sand from big knobby tires. It seemed that somebody had driven an ATV into tunnel. Touching the wall I got an immediate whiff of the earth – it was that mouldering fungus smell you get when you dig in rotting leaves. Unlike the Richardson adit, there is no air movement here; it is absolutely still – like a mausoleum. Knowing the dangers of such an exploration I only stood in the entrance and though I had to fight my curiosity, I turned back for the fresher air of the forest outside.

Check out this rare earth mine near Bancroft – the shaft drops down to a depth of over 400 feet …. Here We found it in the bush by following the surface clues – a mine dump and old beams and tin.

Finding the Croft Uranium Mine – Ontario

Between 1953 and 1955 Croft Uranium Mines worked the area for radioactive minerals. They found betafite, uranite, uranothorite, allanite and pyrochlore. Their appearance is flagged in the pegmatite by a dark red color and quartz that has darkened to a grayish-black. There are also said to be small pink garnets in the gneiss and larger specimens in the pegmatite – some reaching up to 3 centimeters in diameter.

A couple of hundred meters along the mine road I got Maggie to pull over in a little clearing and I continued on foot, leaving her there with the understanding that I would be back as soon as I had found the mine and explored the dumps. She had Shaka with her for company and I had my whistle that I tooted on intermittently so as not to walk unexpectedly into a hunter’s ambush. The whistle also served the dual purpose of letting bears know of my presence as the bush was thick and close to the path and I had no wish to meet the “mother of all bears” in a circumstance of mutual surprise.

The road dropped steeply down into a valley and I soon realized that leaving the car above was a wise move. There was nowhere to turn around, the ruts got deeper, and the track was soon entirely underwater. Beavers had built a stick and mud palisade that held back a stinking organic tidal wave that would one day inundate the swamp below. As for the road, forget it. I climbed across on logs and waded knee-deep in mud, thinking what it might be like during bug season (What looks like a stream in front of the beaver dam is actually the mine road).

On the other side of the beaver dam the track began a slow and steady climb upward. I noticed the appearance of crushed granite where I walked and of course the telltale patches of eastern hemlock. These trees tend to grow in clusters wherever the natural forest has been disturbed. They tell you where to look for hidden human habitation.

I soon discovered the mine dumps on my left and in a marshy gully I unexpectedly found the adit.
