Lithology Comments

Sep 16, 2015 (A Wilson) - Apatite-bearing veins traced across lots 25, 26 and 27 for about 1.6 km. and probably continuing into North Burgess township. On lot 25, the vein is about 10 ft. wide with 3 ft. of almost pure (88 %) apatite, sea green in colour. It is probably a pyroxene-apatite skarn occurring at a marble-gneiss contact. A very large body of pink calcite is exposed upon this lot, and has been mined in a small way for the apatite crystals which occur disseminated in large quantities through it.

Mineralization Comments

Sep 16, 2015 (A Wilson) - The apatite is found associated with wollastonite, mica and zircon as well as the pyroxene and pink calcite. Apatite crystals were found up to 1 ft. or more in length and 4 inches in diameter. Small masses of white, fibrous wollastonite and a few crystals of zircon were observed in a vein with pink lamellar calcite. The veins are associated with pyroxene-apatite skarn zones hosted in white, coarse-grained orthoclase gneisses

1870	91			Only one opening has been made, upon a portion of the calcite vein which here measured 10 feet in width; over 100 tons of phosphate are reported to have been raised. All the work done on this property was performed previous to 1870.
