Discovered in 1886, Westward Ho mine has a recorded production of 3 765.5 tonnes which yielded 34 729.48 grams of gold bullion. 4 000 tonnes were treated at a stamp battery at the mine and tailings were later cyanided. Remaining on site is an indicated 4 900 tonnes of tailings containing 3.97 g/t Au in 3 separate stockpiles. 2 smaller stockpiles were not sampled and are not included in the estimate. Tailings also contain 1.6 g/t Ag, 845 ppm Cu, 575 ppm Pb, 470 ppm Zn and 6 510 ppm As. Cyanide leach tests on underground samples recorded poor gold extractions from 10% to 73% despite reasonably high Au content.
