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.
