Manganese-hematite alteration
Virtual Museum ID: 19-EKM08
Specimen Summary
Hematite is an abundant mineral that is found in the shallow crust. It can be found in sedimentary, igneous, and metamorphic rocks throughout the earth. It is an iron oxide. Pure hematite has 70% iron and 30% oxygen by weight. Its luster can range from earthy to metallic and its colour ranges from red, brown to black and silver. Hematite is used to produce pigments, prepare for heavy media separation, ballast, and a lot of other products.

Advanced Geological Information
The following section provides geological data relating to the specimen or the site it was collected from, when available. Information has been obtained from various sources including private and government datasets but may not be up to date. Any geological time periods or ages listed often relate to the primary geology of the area, and may not be the actual date of an event such as mineral formation.

The Tepee copper occurrence is located on the northwest side of Tepee Creek, in its southern head waters.
The area is underlain by Proterozoic Belt–Purcell Supergroup sediments; mainly rusty weathering argillites of the Upper Aldridge Formation and clean quartzite, siltstone and argillite of the Creston Formation sediments have been intruded by gabbro-diorite Moyie sills and dikes, which are associated locally with mineralized base and precious metal veins. Structure in the area is mostly east-west trending as evidenced by veins and cleavage; bedding tends to undulate but is mostly shallow-dipping.
Locally, strata bound copper occurs as disseminated chalcopyrite and malachite staining hosted in micro-granular light brown siltstone. The mineralization is associated with carbonate, chlorite, sericite and manganese alteration. Three separate mineralized stratigraphic intervals, up to 1.0 metre thick, have been identified. The area is in a much larger argillic-manganese-carbonate alteration zone.
In 2011, two rock samples (SK11-18 and SK11-19) assayed 0.403 and 0.161 per cent copper, respectively (Assessment Report 32807).
In 1998, the area was prospected as the Dek claims. In 2006, Saint Eugene Mining completed 697 line- kilometres of airborne combined magnetic and electromagnetic surveys on the area. The same year Grandeur Resources completed a program geological mapping and rock and soil sampling on the area. During 2007 through 2013, Kootenay Gold completed a program of geological mapping, hand trenching, rock and silt sampling, a 500 line-kilometre airborne magnetic survey and a 500 line- kilometre seismic survey on the area as the KRL claims, Silver Fox property.
