The Ruby and Mable property is located on the lower section of Scorpion Creek, 2.5 kilometres northeast of Slocan. Access is from the Slocan highway via a switchback road on the west slope of Ottawa Hill.
The workings on this property, comprising a 90-metre adit and raise, explore a quartz vein in coarse grained, porphyritic Nelson granite. A total of 10 tonnes of ore was shipped from 1903 to 1904, yielding 6656 grams of silver and 31 grams of gold.
In 2011, Moose Mountain Technical Services, on the behalf of Rainbow Resources Inc., completed a program of prospecting and geochemical (rock and soil) sampling on the area as the Big Strike property.
