James Smith, discoverer of Mount Bischoff tin mine, was the first European to traverse the Forth & Wilmot Rivers. Along with J. Jones and J. Johnson, he prospected along the Forth River in around 1859. Malcolm Campbell discovered the Mount Bell gold mine, near Moina, in 1892, where 100 men were at work soon after. The Shepherd and Murphy, later referred to as the S & M or Moina Tungsten-Tin mine, contributed the greatest part of the total production of tin, tungsten and bismuth from the Moina and Round Mount districts. During periods of intermittent production between 1893 and 1957, an estimated 525t Sn, 255t W03 and 71t Bi have been recovered from the underground and surface workings at this mine.
