This mine was already operational and also successfull, when Solomon Spiro built an adit. He was a German Jewish emigrant who came to Park City in 1894. Working at his uncle's mercantile store, he saved some money and invested it in local mines. He planned an adit to drain water and facilitate the movement of ore out of the mines. But the project was ill-fated and so he sold the tunnel to the nearby Silver King Mine. Soon after the purchase, the new owner discovered a silver lode in this adit, yielding three million dollars worth of high grade silver.
The Silver King Mine became the premier mine in this area, and Solomon Spiro's name became known as synonym for a fortune missed. The owners of Silver King, the partners Thomas Kearns, David Keith, James Ivers, and A.B. Emery accumulated an enormous amount of wealth.
