The miners and prospectors did not, however, exceed a few hundred for several years.
Although in 1880 numerous prospectors discovered extensive deposits of alluvial gold, its exploitation was not generally successful, and farms took the place of mines.
But towards the close of 1870 stones were found at Jagersfontein and at Dutoitspan, far from the Vaal river, and led to a second great rush of prospectors, especially to Dutoitspan, and in 1871 to what is now the Kimberley mine in the neighbourhood of the latter.
Later on, in 1887, both Boers and gold prospectors of all nationalities were overrunning his country, and Umbandine asked for a British resident.
He permitted many members of his regiment who had been prospectors in California to prospect the territory, with the result that mines were located at Stockton, Bingham Canyon, Little Cottonwood and elsewhere; but attempts to smelt lead-silver ore near Stockton about 1866 were not successful, and the mining of precious metals did not become an established industry in the Territory until about 1870.
