FILLOWITE

Na2Ca(Mn,Fe++)7(PO4)6


Brazil Lake Li, Ta, Sn Pegmatite, Yarmouth County
UTM (NAD27)
Zone 20
 Northing 4874957
 Easting 260061
Details:

 Travel northeast from Yarmouth along Highway 340 towards the community of Carleton, Yarmouth County. Approximately 0.5 km south of where the Pleasant Valley Road intersects the highway, turn left (north) onto the gravel Holly Road. Travel northwest along Holly Road for 2.2 km. At that point you will note a skid road leading north from the Holly Road. This skid road was constructed for the Nova Scotia Department of Natural Resources diamond-drilling of the prospect. The pegmatite outcrops that comprise the prospect are located in the woods on both sides of the Holly Road. The diamond-drill skid road leads north for a couple of hundred metres and ends immediately west of one of the pegmatite outcrops. At a point about halfway between this outcrop and the Holly Road is a second outcrop of pegmatite.

Further Info:

 The Brazil Lake Pegmatite is characterized by the presence of very large spodumene crystals (<60cm), and an accessory mineral assemblage which includes; tourmaline, apatite, cassiterite, wolframite, zircon, columbite/tantalite, epidote and very minor lithiophilite (Li(Mn,Fe)PO4), fillowite, amblygonite/montebrasite and cookeite (Hughes, 1995). Although small, dark green beryl crystals were reported to occur within the pegmatite (Hutchinson, 1982), no beryl was identified by Corey (1995) or Hughes (1995) during their investigations. However, abundant dark green tourmaline crystals do occur and may have been mistaken for beryl.
