The Amanda showing is about 1 kilometre northeast of the confluence of Siwash and Galena creeks and 38.5 kilometres northeast of Princeton.

Silver-zinc-lead mineralization occurs at the southeast end of a stock of quartz porphyritic monzonite/granite, along the contact with granite of the Middle Jurassic Osprey Lake batholith. This stock is one of a series of small granitic bodies of early Tertiary age referred to as the Otter intrusions.

Mineralization consists of galena, sphalerite and pyrite, as small grains in fractures in the vicinity of the contact between the two intrusions. Similar mineralization occurs in the monzonite along shear zones. A sample from the contact assayed trace silver, 0.01 per cent lead and 0.02 per cent zinc (A.L. Edgeworth, 1970, certificate of assay, sample No. 2). A grab sample from a mineralized shear taken immediately north of the contact assayed 7 grams per tonne silver, 0.25 per cent lead and 4.15 per cent zinc (sample No. 3).

In 1996, diamond drilling to the south yielded intercepts of up to 25.2 grams per tonne silver, 0.138 per cent zinc and greater than 1.00 per cent copper over 0.9 metre in hole 96-3 (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

In 1997, diamond drilling on the area yielded intercepts of up to 1.35 grams per tonne gold, 2.2 grams per tonne silver, 4.27 per cent copper, 0.16 per cent lead and 0.94 per cent zinc over 1.44 metres in hole 97-1 (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

In 2001, a drill hole (01-1) yielded 0.88 gram per tonne gold and 329.5 grams per tonne silver over 0.73 metre (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

The area has been explored in conjunction with the nearby Snowstorm (MINFILE 092HNE032) occurrence and completed exploration history can be found there.
