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.

Olympia was chosen as the temporary seat of government, and Governor Stevens at once set to work to extinguish the Indian titles to land and to survey a route for a railway, which was later to become the Northern Pacific.
