Off this shore lay Silver Islet, once a barren rock about eighty feet in diameter, where Thomas Macfarlane discovered silver in 1868. In 1870, a company headed by A.H. Sibley purchased the claim, and partner W.B. Frue became mine captain. Frue fought a constant battle against the lake, which undermined the extensive crib work that supported the limited working space. Even with that problem and the challenges of housing miners and transporting supplies in the isolated region, the mine produced $3,250,000 worth of silver ore before closing in 1884.
