This showing is situated immediately east of Siwash Creek, 1 kilometre north-northwest of the creek's confluence with Tepee Creek.

The Fisher Maiden occurrence consists of a number of shear zones in granite of the Middle Jurassic Osprey Lake batholith. Several dikes related to a body of granite of the early Tertiary Otter intrusions outcrop in the vicinity.

The shears are silicified and mineralized with hematite, pyrite and chalcopyrite. An area of intensely fractured granite exhibits malachite over an area of 2.8 square metres. One shear zone exposed in a 15-metres long adit contains fine-grained galena and sphalerite, with minor pyrite and chalcopyrite over a width of up to 10 centimetres and a strike length of 5 metres.

In 1989, a sample from this shear analysed 21.9 grams per tonne gold, 161 grams per tonne silver, 0.59 per cent copper, 10.56 per cent zinc and 15.97 per cent lead (Assessment Report 19472, page 21, sample 24677). A second sample from a trench 130 metres south-southeast of the adit analysed 0.09 gram per tonne gold, 8.6 grams per tonne silver, 0.059 per cent copper, greater than 1 per cent zinc and 0.0244 per cent lead (Assessment Report 18211, rock geochemistry map, sample 31).

In 1994, diamond drilling yielded up to 1.23 gram per tonne gold, 30.2 grams per tonne silver, 0.114 per cent copper and greater than 5.00 and 1.00 per cent lead and zinc, respectively, over 1.5 metres in hole 94-30 (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

In 2006, Ravencrest Resources Inc. completed a program of prospecting and geochemical (rock, stream sediment and soil) sampling on the area as the Siwash Creek property. A grab sample (06KRP402) of quartz vein material assayed 7.68 grams per tonne gold, 5.71 per cent zinc and 16.28 per cent lead (Besserer, D.J. (2007-05-27): Technical report on the precious and base metal potential of the Siwash Creek Property).

In 2011, a grab sample (11KRP101) assayed 13.5 grams per tonne gold, 102 grams per tonne silver, 0.723 per cent copper, 4.60 per cent zinc and greater than 20.0 per cent lead (Moroney, D.M. (2012-06-04): Technical Report on the Siwash Creek and River Wild Properties).

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