The Exchange property is at 1600 metres elevation on the ridge southwest of Dayton Creek, 3 kilometres due east of Slocan. Access to the property is from a switchback mountain road that joins the Springer Creek road just east of the Slocan highway.

A quartz vein in Nelson granite has been explored by three adits, a shaft and a 30-metre winze sunk from the lowest adit. The vein is 1.5 metres wide, banded with clear and milky white quartz and pyrite accompanied by some galena, sphalerite and ancillary silver-bearing minerals.

Production from this property in 1896 amounted to 4.5 tonnes averaging 41 grams per tonne gold and 5100 grams per tonne silver. In 1940, 12 tonnes produced 25,784 grams of silver and 156 grams of gold. Total production is estimated to be more than 50 tonnes, although records are incomplete.
