The Hector, Danira and Keystone Fraction claims are located at an elevation of approximately 760 metres on an east facing slope, approximately 850 metres northwest of Ainsworth.
Regionally, the area is underlain by hornblende schists, limestone and banded quartzite of the Upper Mississippian to Permian Milford Formation and basaltic volcanic rocks of the Carboniferous to Permian Kaslo Group. Granodioritic intrusive rocks of the Middle Jurassic Nelson Batholith are exposed to the west.
The claims cover two quartz veins that strike between 330 and 335 degrees, dip 40 to 60 degrees west and are parallel to the foliation of the enclosing rocks. These rocks are quartz mica-schist and quartzites of the Mississippian to Lower Permian Milford Group. The quartz vein on the Danira is on strike with the Highlander vein to the south. It follows the hangingwall of a lamprophyre sill and is up to 1 metre thick. It contains lenses of sphalerite, galena, pyrite and minor chalcopyrite up to approximately 30 centimetres thick. The vein on the Hector as exposed in an old trench and shaft consist of 60 to 90 centimetres of rusty quartz containing lenses of galena, sphalerite, pyrite and chalcopyrite.
There is recorded production for the Hector & Danira for 1942 and 1949 when 16 tonnes was mined. From this, 4665 grams of silver, 5761 kilograms of lead and 1027 kilograms of zinc were recovered.
Work History
The Hector claim, located in 1904, has been developed by a 366-metre adit with 30.5 metres of drifting on a shear at 174 metres from the portal. A raise was driven to the surface from the drift.
On the Danira claim, which was located in 1891, a 7.6 metre shaft was sunk on the vein. A crosscut adit, collared 55 metres south, was driven westward to intersect the vein 23 metres from the portal. A drift was driven to the north for 53 metres and from the end of this drift a raise was driven to connect with the bottom of the old shaft. Halfway along the drift a second raise was driven on the vein to the surface. In 1951 approximately 366 metres of diamond drilling in eight holes was done by the Ainsworth Syndicate on the Danira claim.
Yale Lead & Zinc Mines Ltd. acquired the Hector, Danira and Keystone Fraction claims in 1954. Some of the above-mentioned development was done by this company in 1954 to 1955. Most of the work was disappointing.
In 1979, David Minerals Ltd. conducted a program of geochemical (stream and silt) sampling on the area immediately south as the Peanut Butter claims of the Ainsworth property.
In 2010 and 2012, David Wallach prospected and sampled the area as the Ainsworth property. In 2010, three rock samples (8R269053 through 8R269055) from the area of the adit yielded values from 0.01 to 0.33 per cent copper, 0.78 to 8.19 per cent lead, 0.65 to 13.29 per cent zinc and 20 to 54 grams per tonne silver (Assessment Report 32281).
