Silver Islet 1868

Off this shore lies Silver Islet, once a barren rock, measuring about eighty feet in diameter, where silver was discovered in 1868 by Thomas Macfarlane. The claim was purchased in 1870 by a company headed by A.H. Sibley, and one of the partners, W.B. Frue, was appointed mine captain. Frue waged a constant battle against the lake, which undermined extensive crib work used to bolster the restricted working spaces. Despite this problem and the difficulty of housing miners and transporting supplies in the isolated region, this famous mine produced $3,250,000 worth of silver ore before it was closed in 1884.
