Rare Earth Results From Playfair South Block

Playfair Mining Ltd. (TSX VENTURE:PLY) is pleased to announce that Rare Earth
Metals (TSX VENTURE:RA) has completed preliminary sampling of the 2010 airborne
geophysical anomalies on the Playfair South claim block. 


Rare Earth Metals can earn a 51 percent interest in Playfair's 313 claim unit
property as described in Playfair's February 17th, 2010 news release. 


Playfair Mining's assets include the Seal Lake copper-silver camp, where the
company is targeting sizable Kupferschiefer-style Cu-Ag mineralization. Playfair
also owns four advanced stage tungsten deposits in Canada. While the Seal Lake
copper-silver project is the company's current exploration focus, the tungsten
and the rare earth assets give the company unique exposure to a portfolio of
strategic mineral exploration properties poised to benefit from supply and
demand imbalances being created by China. 


The Playfair South Block is located in the southwest portion of the historical
Letitia Lake - Red Wine rare earth metals exploration camp; encompassing 15
airborne geophysical anomaly clusters that have strike extents ranging from 200
meters to 1000 meters. Prospecting and geological mapping completed to date by
RA have resulted in 3 previously unreported mineralized showings on the
PLY-S-02, PLY-S-05 and PLY-S-10 radiometric anomalies. The rare earth metal
mineralization is hosted by predominantly peralkaline intrusive rocks and is
generally characterized by an abundance of Eudialyte mineralization and is
dominated by heavy rare earth oxides and Zirconium (ZrO2). Geochemical analyses
of prospect samples from three of the new discoveries follow:


PLY-S-02 - (800 metre long radiometric anomaly) Prospect samples ranged from
0.11% to 1.38% TREO and 0.02% to 3.01% ZrO2. The TREO (total rare earth oxides)
values ranged from 37% to 43% HREO (heavy rare earth oxides). 


PLY-S-05 - (1000 metre long radiometric anomaly) Results here include the
discovery of a 5 to 13 meter wide actinolite chlorite schist zone exposed for a
strike length of 110 meters. Traces of eudialyte have been reported and
geochemical analysis of prospect samples returned values that ranged from 0.51%
to 2.41% TREO and 0.09% to 0.48% ZrO2. The TREO values ranged from 5% to 20%
HREO.


PLY-S-10 (CD Zone) - Located 2 kilometres southwest of the PLY-S-05 anomaly,
this mineralization is described as a minimum 3 meter wide pegmatitic gossan
zone with rare metal values ranging from 0.19% to 5.37% TREO and 0.05% to 2.56%
ZrO2. The TREO values ranged from 26% to 85% HREO. 


These zones are scheduled for channel sampling. Additionally, a number of other
disseminated eudialyte zones have been located, however, analyses from prospect
samples collected from these areas are pending.


Don Moore, Playfair's Chairman stated, "We are pleased that the 2010 exploration
work at Red Wine is beginning to show promise. In addition to the known
historical showings on the PLY South Block, Rare Earth Metals has discovered
three new REE zones so far. We look forward to the results of the detailed
follow-up work." 


About Letitia Lake - Red Wine Exploration, Labrador Canada 

The historic Letitia Lake - Red Wine exploration camp hosts numerous showings
containing rare metals (beryllium, zirconium, yttrium and niobium) and rare
earth elements (REE). This camp has many regional-scale lithological and
geochemical similarities to the Strange Lake REE-Zr-Y-Nb-beryllium exploration
camp, located 260 kilometres to the northwest. Like Strange Lake the Red Wine
area is underlain by middle mesoproterozoic peralkaline rocks which are enriched
in rare earth elements and other uncommon metals. The Red Wine REE district is
located 120 km northeast of Churchill Falls, Labrador and is within 40
kilometres of an existing resource road originating at Churchill Falls. The
estimated centre of the Red Wine REE camp is only 10 kilometres southwest of the
western extent of Playfair's Seal Lake Copper-Silver exploration property. 


China produces more than 90% of the world's REE and has recently taken steps to
hoard its own production creating well founded supply concerns for the worlds
developed countries. Rare earth metals and elements are used in a variety of
critical ways, such as in the production of magnets/engines/batteries in hybrid
cars, consumable electronics, (Blackberries, iPhones, flat screen televisions),
miscellaneous green energy technologies and military applications.
