Playfair Mining Ltd.: Seal Lake Copper Silver Acquisition
January 27 2010 - 7:30AM
Marketwired
Playfair Mining Ltd. (TSX VENTURE: PLY) is pleased to announce that
it has acquired, by staking, a 100% interest in 673 claims covering
16,825 hectares in the Seal Lake area of Central Labrador. The
property covers some 136 copper and copper-silver occurrences
including 16 copper-silver showings and 9 copper silver prospects,
all discovered mainly via prospecting in the 1950's. Almost all the
showings and prospects occur within a consistent and laterally
extensive stratigraphic interval - the basal gray shale of the
Upper Adeline Island Formation. The copper-silver enriched Adeline
Island Formation is believed to form a canoe shape, with the rock
unit outcropping over an estimated area measuring about 33km long
by 4.4km wide. Playfair's Seal Lake Copper Silver Project covers
the entire mapped extent of the favourable sedimentary unit and its
probable subsurface continuation.
The Seal Lake Basin has been explored intermittently for copper
since 1950 by a number of senior companies, including Frobisher,
Kenneco (a Kennecott subsidiary), Brinex, Beth-Canada (a subsidiary
of Bethlehem Steel) and Noranda Exploration. Historical work was
conducted at a time when copper prices were low and infrastructure
was not as advanced as it is today. Now, with copper trading at
much higher prices, the Trans-Labrador Highway 110km to the south
and the Churchill Falls Hydro dam 180km to the southwest, the
preliminary results obtained by this group of companies suggest
that Seal Lake is a large, target-rich area with potentially
economically significant mineralization. The project area is
located 140km northwest of Goose Bay and importantly a hydro
project access road is only 50km west of the western limit of the
property.
Mineralization at Seal Lake has been recognized since the 1970's
as a reduced facies sediment-hosted copper-silver mineralization of
Kuperschiefer-type. It is most closely analogous to the White Pine
deposit in Michigan, USA that is reported by the USGS to contain
688 million tonnes grading 1.2% copper and 40 gpt silver.
Europe's Kupferschiefer (medieval miners term for "copper
shale") Basin is host to one of the biggest sediment-hosted copper
districts of the world, second only to the Central African
Copperbelt. The earliest traces of mining in the Kupferschiefer
date back to prehistoric times with the main mineralized regions in
Germany and Poland being mined systematically since medieval times.
Several major mines are currently operating in Poland where the
deposit at Lubin is reported by the USGS to contain 2,600 million
tonnes containing 2% copper and 30 gpt silver. Table 2 below
illustrates the impressive size and grade of such sedimentary
deposits found around the world.
Don Moore, Playfair's Chairman stated, "Playfair is changing
focus to concentrate in the near term on the new copper silver
opportunity in the Seal Lake basin with its attention grabbing
district scale. Kupferschiefer type mineralization often stretches
over great distances - in Europe, they run from southern Germany
through Poland; which is currently Europe's largest copper and
silver producer. Seal Lake is a major opportunity for Playfair. The
mineralization and geology of this new project is similar to the
Kupferschiefer type copper-silver deposits that are the focus of
ongoing work at Hana Mining's Ghanzi property."
"Playfair continues to believe that there is a strong case for
an upcoming global Tungsten shortage. With four high-grade Tungsten
deposits Playfair remains well positioned to take advantage of the
expected upcoming global Tungsten shortage and associated Tungsten
price increase."
Previous work at Seal Lake has seen some very interesting
results reported by major mining companies. Playfair believes this
data is relevant and reliable, but notes that these historic data
have not been verified. Chip sample results reported by Noranda in
1991 show that "Mineralization in the area of interest consists of
disseminated chalcocite with lesser bornite and chalcopyrite in
grey-green reduced shales. The Whiskey Lake No. 150 showing had the
best results. This was 2.94% Cu and 45.85 g/t Ag over 11.0 m which
includes 5.1% Cu and 72.67g/t Ag over 4.0m". Table 1 below shows

Copper-Silver Camp.

Playfair is currently completing a digital compilation of
historical exploration and government geoscientific data for the
region. On completion of this data compilation, Playfair will
detail work for the 2010 season, which may include more detailed
lake sediment-till sampling, prospecting, geological mapping, an
airborne radiometric-magnetic geophysical survey and possibly
diamond drill testing.
