Q.E.D. started life as an alluvial wash or deep lead at the western edge of the goldfield. It was one of several of these areas at Kanowna including North Lead, Fitzroy, South Lead, Golden Valley and Six Mile.
Q.E.D. had an absence of ironstone, unlike the other leads, and was composed of quartz pebbles permeated with gold. The lead went north-west, then turned sharply east, before doubling back on itself in a westerly direction. At the southern end the wash was 32 feet at depth below the surface but this increased further north to 43 feet.
The lead was discovered in the beginning of 1898, and soon hundreds of men were feverishly digging shafts, piling up mullock and erected windlasses. As one example, James and Thiedes was one of the first leases pegged, and one 50 tonne crushing resulted in 334 ounces. By the end of 1898 it was all over.
The richest claims were Honber and Raymond, Swanson and party, Arthur and party.
The late 1970's, the remaining wash was extracted by a shallow pit and processed by the heap leach method by the Golden Valley joint venture.
