quartz siderite chalcopyrite

Virtual Museum ID: 19-Ed12

Specimen Summary

Chalcopyrite is an important copper ore mineral found in many different types of copper deposit. It is sometimes mistaken for Gold because of its bright yellow colour; however, it is harder, more common, and chalcopyrite commonly occurs with other copper sulphide minerals such as bornite and weathers to malachite and azurite.

Quartz is the second most abundant mineral on Earth, present in many different types of rocks. Although usually clear or milky white in colour, quartz is found in a variety of colours due to impurities in the crystal structure. Pure quartz consists of silicon and oxygen only, but atoms of other elements often make their way into the quartz crystal structure, colouring the crystals. Some varieties of quartz, like purple amethyst and yellow citrine, are considered to be semi-precious gemstones and have been used since ancient times to make jewellery and decorative objects. Well-formed (euhedral) crystals of quartz have a hexagonal cross section and are highly collectible.

Site Details:

The exact location of the Edith showing is not known. It is assumed to be on the Edith claim, about 2.5 kilometres north of Kimball Lake and approximately 700 metres west of American Creek.

The area is underlain by rocks of the Lower Jurassic Betty Creek Formation (Hazelton Group (Bulletin 63). These rocks comprise green, red, purple and black volcanic breccia, conglomerate, sandstone, siltstone and tuff. They strike north-northeast and lie on the west limb of the faulted, north-northeast trending American Creek anticline.

There is no information available on the nature of the mineralization. A grab(?) sample collected in 1932 assayed 4114.3 grams per tonne silver, 19.2 per cent zinc, 12.6 per cent lead, 3.4 grams per tonne gold and 1.2 per cent copper (Minister of Mines Annual Report 1932, page 60). Mineralization is inferred to be a polymetallic quartz vein similar to the Bugnello showing (104A 112) located 950 metres south. At the Bugnello, mineralization consists of pyrite, sphalerite, galena and chalcopyrite in quartz-carbonate veins.

In 1932, K. McLeod owned the Edith claim group. The showing was discovered during intensive prospecting that year. No further work has been reported on the showing.
