The Hendersons showing is located on the west side of the Kitsault River, 14.0 kilometres due north of Alice Arm. In 1920, two claims were described as being located along the Dolly Varden Railroad just below Spring camp, or Mile 9.

The region is underlain by Upper Triassic Stuhini Group and Lower Jurassic Hazelton Group volcanics and sediments. These are folded into a northwest trending anticline.

The showing consists of a quartz-breccia vein and a zone of pyritic quartz-calcite veinlets. The vein occurs along a dioritic dike and is 0.3 metre wide. The veinlets occur in a 15 metre wide zone and are hosted in Stuhini Group black siltstone. A sample of good grade silver ore is reported to have come from the vicinity of these showings (Minister of Mines Annual Report 1919, page 52).

In 2005, Kitsault Resources Ltd. completed a reconnaissance stream sediment survey on the area as the Kitsault Gold property.
