Playfair Reports Drill Results From Seal Lake

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/10/11 -- Playfair Mining Ltd. (TSX VENTURE: PLY) is pleased to provide a report on the recently completed drill program at its 100% owned copper-silver project at Seal Lake in Central Labrador. A total of 4,350.4 metres was drilled in 24 holes. All analytical results have now been received.

All but one of the twenty four drillholes intersected the favourable reduced Adeline Island Formation rocks with cumulative thicknesses ranging from 136.6 in drillhole SL11-22 to 0.7 metres in drillhole SL11-17. The cumulative thickness of 136.6 metres in hole SL11-22 comprises eight separate sections over 214.8 metres of core with the thickest single section being 64.2 metres. Potentially economic copper and silver grades were intersected in three of Playfair's previously reported drillholes. Twenty of the remaining twenty one drillholes contain anomalous amounts of copper.

These results provide support to Playfair's exploration theory that the extensive copper-silver mineralization at Seal Lake is syngenetic or diagenetic (that is formed at the same time as the host rocks or shortly afterwards) and not epigenetic (that is formed at a considerably later time than the host rocks). The implication is that the copper silver mineralization occurs throughout the Seal Lake basin and that considerable tonnage can potentially be developed. The large variation in thickness of the favourable unit also provides encouragement.

The Seal Lake project covers 16,825 hectares in Central Labrador. 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, are known on the property. Almost all the showings and prospects occur within a consistent and laterally extensive stratigraphic interval - the basal gray shale and adjacent quartzite of the Upper Adeline Island Formation. The copper-silver enriched Adeline Island Formation is believed to form a canoe shape, with the rock unit extending over an estimated area measuring about 33km long by up to 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.

Playfair believes the mineralization at Seal Lake is a reduced facies sediment-hosted copper-silver mineralization of Kuperschiefer-type. It is geologically 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. Playfair's current drill program was designed to test this geological interpretation by drilling widely spaced holes in several parts of the extensive property.

In addition to the Seal Lake copper-silver exploration opportunity, Playfair has four properties with substantial high-grade tungsten deposits. Playfair's four tungsten deposits have all had significant work completed on them. Two of the deposits (Risby and Grey River) have NI 43-101 compliant resource estimates while the other two deposits (Lened and Clea) have historical noncompliant NI43-101 resource calculations. Playfair continues to believe that there is a strong case for an impending global Tungsten shortage, as is evidenced by the continued strong rebound in the price of Tungsten.

Tungsten has recently traded to an all-time high of $455 per Metric Ton Unit of APT (or $20.64 per pound), an increase of more than 100% over the last year. Please see our website for an internet link to the spot Tungsten price.

D. Neil Briggs, Director

Core samples were collected under the supervision of James Harris, P.Geo. BTW diameter diamond core was descriptively logged on site, aligned, marked for sampling and then cut in half, longitudinally, using a rock saw. One-half of the core is preserved on site in core boxes for verification and future reference. The samples comprising the other half of the core were bagged, sealed and delivered directly to ActLabs preparation facility in Happy Valley- Goose Bay Labrador, they were dried, crushed and pulped. Sample pulps were then delivered to ActLabs in Ancaster Ontario (an ISO 17025 accredited facility). Samples were crushed to with up to 75% passing 2mm and split using a riffle splitter. An approximately 250 gram sub-sample split was pulverized using a ringmill to approximately minus 150 mesh (105 micron). A 0.5 gram split from the resulting pulp was then subjected to an aqua regia digestions and a multi-element ICP-MS analysis (code Ultratrace 1). Results with copper greater than 5,000 ppm were subjected to a sodium peroxide fusion digestion and ICP-OES analysis (code 8). Results with silver greater than 30 ppm values were subjected to an analysis by fire assay with a gravimetric finish (code 8-Ag). All coarse rejects and pulps are currently stored at Actlabs Labrador. Assay standards and blanks were inserted into sample shipments as a quality control measure in addition to the internal quality control measures applied by the laboratory.
