Graystone Company
Anno
unces Copper Campaign #2 Update
Las Vegas, Nevada. August 12, 2014
--
The
Graystone Company
(OTC
: GYST)
announced today that its wholly owned subsidiary, Grupo Mineral Inca, SAC (GMI)
has
compiled approximately 130 tons of high grade copper ore so far for its Copper
Campaign #2. The company
has started shipping the ore to its processing
plant in
Nazca, Peru. T
he company conducted an aggregate test sampling of the 130 tons of
ore and the percentage of copper in the ore is currently testing
at
an estimated 20
-
22
%
increase compared to the fina
l results from
profitable c
ampaign #1.
In addition, the lab results also indicate a recoverable amount of
gold, which
the
company’s
metal ore engineer will
also
recover
with the copper as a concentrate
via
froth flotation.
The process of froth flotation e
ntails crushing and grinding the ore to a fine size. This
fine grinding separates the individual mineral particles from the waste rock and other
junk
mineral particles. The grinding is done in water with the resultant slurry called the
pulp. The pulp is pr
ocessed in the flotation cells, which agitate the mixture and introduce
air as small bubbles. The ability of a mineral to float depends upon its surface properties.
Chemical modification of these properties enables the mineral particles to attach to an
air
bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to
the surface of the froth or foam that is present on the flotation cell. Even though the air
bubbles often break at this point, the mineral remains on the surface of
the froth. The
mineral is physically separated from the remaining pulp material and is removed for
further processing.

during campaign #
1 are located on
the company’s y

As in campaign #1, the company intends on selling it’s processed concentrate to its
Chinese concentrate buyers.
Because of the higher quality ore and our repeat business, the
processing plant has
reduced GMI
’s
minimum quota f
r
om 200 tons of ore to 150 tons.
GMI is also in the final stages of negotiating a 45 ton bulk ore purchase
that, if
completed this week, would enable the company to
start processing its ore as early as
next week.
As a reminder,
The company
’s campaign #1
pr
oduced 203 tons of copper ore at a total cost
of $108.37
per ton
and took over 90 days to complete.
The company sold its copper concentrate
e
qualing $184.72 per ton of ore.
Because of
the
expected
gold recovery
that
was not
present in campaign #1
and
the
increased
copper
purity
,
The
Company
anticipates
seeing a
n
increase in
its net profit for
campaign #2.
