The Defiance (Lot 758) is located at an elevation of 1050 metres, northeast of Greenwood and adjacent to the Strathmore claim (082ESE215).

A quartz vein occurs in granodiorite of the Jurassic-Cretaceous Greenwood Stock; it is mineralized with galena, pyrite, gold and silver. Ore extraction is difficult due to flat-lying faults. Volcaniclastics of the Triassic Brooklyn Formation lie east of the granodiorite.

The claim was Crown Granted to H.J. Cole and G.F. Steele in 1898. R. Lee developed the claim in 1924 with open cuts, shafts and cross-cuts. Production in 1893 and 1924 totalled 4 tonnes, resulting in 48,054 grams of silver, 187 grams of gold and 122 kilograms of lead.

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of soil, stream sediment and rock sampling, geological mapping and ground geophysical surveys on the area as the Overlander area of the Greenwood property.
