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.

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.

The Reeves Tin Pit is located 5.1 km west on the Dalhousie
Road (Forties Road) from the village of New Ross, Lunenburg
County. The prospect is found within the community of Forties
and 0.5 km south of road on the Reeves farm. Reeves is a common
name in the New Ross area. The prospect may be reached by going
80 metres south along a woods road that starts at a small man-made
pond behind the barn on the Reeve's farm. At that point turn
west from the woods road onto a foot path and walk southwest
for 120 m to a cleared area. The prospect is located in this
cleared area and in 1982 consisted of a water-filled pit, outcrops
and overburden dumps (O'Reilly et al., 1982). Since 1982 the
pit has been filled in by the land owner but dump material can
be found laying about.

Mineralization: Flecks of fluorite and blue-turquoise
fluorapatite are common in the pegmatite and associated leucogranite
that accompanies the pegmatite. The mineral assemblage that
is reported to occur in the central zone of the pegmatite is
impressive and includes: cassiterite, amblygonite, lepidolite,
fluorite, topaz, tourmaline, beryl, wolframite, scheelite, columbite,
durangite, metatorbenite, tapiolite and monazite. A Department
of Mines and Energy field check reported in 1982 indicates that
most of these minerals are not obvious and only fluorite, lepidolite
and fluorapatite were noted (O'Reilly, et al., 1982).
Faribault (1908) reported that a pit was dug in 1903, uncovering
cassiterite- and fluorite-bearing quartz boulders. Consequently,
digging continued and a shaft was sunk into bedrock with work
continuing for the next few years. A pit was sunk (7.5 m deep,
3.6 m long and 3 m wide) on a pegmatitic segregation within
light grey leucogranite. The site has been visited by numerous
persons since Faribault's time but the dyke was apparently not
visible due to the water level in the pit and the fact that
much of the outcrop had since been covered over by dump material.
