The Dixie Hummer property is situated near the headwaters of Howson Creek at 2010 metres elevation above sea level, in the Slocan Mining Division.

The claim was Crown-granted to N. Hickey in 1902.

A small amount of digging was done years ago on the ridge crest on a breccia zone in argillite. Stripping of a limestone bed which outcrops on the steep north slope of the ridge uncovered some sulphide mineralization.

Regionally, the area lies on the western margin of the Kootenay Arc, in allochthonous rocks of the Quesnel Terrane. In the vicinity of the occurrence, the Quesnel Terrane is dominated by very fine grained clastic sedimentary rocks of the Upper Triassic Slocan Group that include locally weakly metamorphosed argillite, quartzite, limestone and some tuffaceous rocks. These sedimentary rocks are intruded by dikes, sills and stocks of varied composition and origin. Permian and/or Triassic Kaslo Group metamorphosed volcanic rocks occur to the north of the Slocan Group rocks. Middle Jurassic Nelson intrusions are immediately south of the Slocan Group and are inferred to be the source of granitic to pegmatitic sills and dikes found in the area. The Nelson intrusions comprise at least six texturally and compositionally distinct phases ranging from diorite to lamprophyre. The most dominant phase is a medium to coarse grained potassium feldspar porphyritic granite (Paper 1989-5).

The occurrence is hosted by predominantly interbedded black argillite and limestone of the Slocan Group. The sedimentary rocks have been folded, fractured, faulted and regionally metamorphosed to greenschist facies. The regional northwest trending asymmetric Slocan syncline is thought to be Middle Jurassic and is the first recognizable deformation in the sequence. Several fault structures are evident and host vein mineralization. Later stage normal and thrust faults and shearing have chopped, deformed and remobilized the veins and mineralization. Drag features are also present.

Mineralization is hosted in a breccia zone at the contact between argillite and limestone strata. Most of the mineralization appears to be as replacement of limestone and consists of quartz and coarse calcite with minor galena and sphalerite. Azurite and limonite are also present in minor amounts. The breccia vein is exposed near the top of the ridge on the Dixie Hummer Crown grant where it is about 1.5 metres wide.

Four short adits were driven in a northerly direction from the Minnesota Fractional Reverted Crown grant but all failed to intersect the mineralized zone. Several large mineralized boulders were found on the Minnesota claim below the workings. A grab sample collected from one of these boulders in 1926 assayed 5232 grams per tonne silver, 72.9 per cent lead and 1.4 per cent zinc (Minister of Mines Annual Report 1926). No production is reported for this property.
