red-bridge Mine

The Red Bridge or Ulster Mine was a relatively old and short-lived operation having been first worked in 1836. It was operated by the North American Coal & Mining Company. In 1838, the company drove an adit to intersect the vein which was sufficiently driven for drainage and the expectation of hauling a large amount of ore, should it be found. The operation included four tunnels, two shafts and open pit excavations. The vein contained galena and sphalerite.

In 1840, the mine was abandoned and little if any further development work was done thereafter. One adit remains well preserved but flooded.

The mine's more recent claim to fame has been its quartz crystals, some of which have been featured in notable mineral collections.
