<P> The gold rush transformed the Western Australian economy as gold production soared from 22,806 ounces in 1890 to 1,643,876 ounces in 1900 and this was matched by the fourfold increase in WA's population from 46,290 in 1890 to 184,124 reported in the 1901 census . </P> <P> Gold was rediscovered near Tarnagulla on 6 November 1906 (Melbourne Cup Day), when a miner who had prospected the district for years obtained seven ounces of gold from a shaft nineteen feet deep . With some fairly large nuggets being found soon after, the so - called Poseidon rush, named after the horse that had won the Melbourne Cup that year, set in with "men of all ranks and professions...trying their luck on the field". Several of the nuggets were unearthed within a few inches of the surface . The largest weighed 953 ounces (27 kg) and two others weighed 703 (20 kg) and 675 ounces (19 kg) respectively . The shallow ground was soon worked out, but operations have given satisfactory results in the deeper alluvial until 1912 . </P>
