Blackheath Reports 11.4 metres of 1.56% WO3 at Covas Tungsten Project
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/01/13 -- Blackheath Resources Inc. (TSX VENTURE: BHR)(FRANKFURT: 04B) is pleased to report further drilling results from the Covas Tungsten Project in northern Portugal. The Phase 1 drilling program is designed to confirm and test known skarn-related mineral zones and extensions as well as new targets at Covas. Initial results are available from drilling at the Lapa Grande and Castelo zones as well as additional holes at Telheira. (See plan of project area: http://media3.marketwire.com/docs/b228a.pdf)
Results from drilling to date include:
-- 1.56% WO3 over 11.40 metres at Lapa Grande including
-- 2.89% WO3 over 5.10 metres in Hole CO 13-12
-- 0.79% WO3 over 1.55 metres at Telheira in Hole CO 10-12
-- 2.11% WO3 over 7.98 metres at Telheira including
-- 4.24% WO3 over 2.55 metres in previously reported Hole CO 7-12
-- Expanded mineralization at Castelo target
The initial diamond drilling program has been completed. Fifteen holes were drilled in five target areas around the Skarn Ring and within the central Covas Dome area for a total of 1,606 metres. Results from thirteen of the holes are available and best results came from the Telheira and Lapa Grande target areas, where historic drilling had previously demonstrated the potential for high grade tungsten mineralization. In addition, step-out drilling at the Castelo target area showed potential for tungsten mineralization southeast of previously documented mineralized areas. Results of the remaining two holes drilled at Lapa Grande will be released when available. All holes are vertical drill holes and intercepts are considered to represent the true thickness or close to the true thickness of the mostly flat-lying mineralized zones.
"We are very pleased with these results from our first drilling programme at the Covas Tungsten Project," said James Robertson, President & CEO of Blackheath Resources. "We have confirmed that there are zones of high grade tungsten mineralization as well as strong potential for expansion and we look forward to planning our next campaign at Covas."
Lapa Grande
Five holes were drilled at the Lapa Grande target area. Hole CO 13-12 intercepted 11.40 metres of 1.56% WO3, including 5.10 metres of 2.89% WO3. Hole CO 14-12 intercepted 2.80 metres of 0.77% WO3. Results for the first three holes are summarized below, while results for the final two holes are still in process. Drilling at Lapa Grande validated the historic work, with high grade results, and demonstrated the potential for expansion of the size of the mineralized zone. The Lapa Grande target area is larger than the Telheira zone, as presently known, and historically has not been well-explored. The potential for further mineralization lies to the northwest, southwest, and south. (See drill hole location map for Lapa Grande)

Telheira
Five drill holes were completed at Telheira. The first two holes, CO 7-12 and CO 8-12A, were reported previously and validated previous drilling with high grade results. The next three holes, CO 9-12, CO 10-12, and CO 11-12, expanded the zone of known tungsten mineralization in the target area. There is further mineralization potential on the north, west, and south sides of the Telheira zone, as well as in the nearby Telheira north and southeast target areas.

Castelo
Re-interpretation of the historic data indicated the potential for expanding the zone of known mineralization at Castelo, as well as the potential for adding new lenses of mineralization to the southeast of the original zone. Three holes were drilled in the Castelo target area. The third hole, CO 19-13, was drilled about 250 metres southeast of the main Castelo mineralization, and intercepted 4.0 metres of 0.26% WO3, confirming the start of a new zone of tungsten mineralization. In addition, CO 18-12, drilled at the northwest extremity of known Castelo mineralization, cut mineralized skarn at surface, indicating potential for further expansion to the northwest and west in this area.

Positive results from the drilling program completed at Telheira, Lapa Grande, and Castelo suggest that there is room for further expansion of the known, close-to-surface tungsten mineralization in these zones, as well as for discovery of new mineralization. Further work, including re-logging and sampling of historic core, more detailed mapping and targeting, and continued review and re-interpretation of the historic data will assist in planning of further drill exploration and delineation of these mineral bodies in the next phase of drilling. In addition, while results from drilling the intrusion target in the central Covas Dome did not include anomalous values of tungsten or gold, preliminary geological mapping, rock-chip sampling and interpretation of geophysical data all indicate the possibility for the presence of mineralization along a pronounced east-west lineament, cutting the Covas target area. Further surface work will be undertaken in the coming field season, prior to follow-up drilling in the Dome area.
Covas is a past producing tungsten mine and remaining historic resources (indicated and inferred) on the property have been estimated at 922,900 tonnes of 0.78% WO3 by Union Carbide in 1980, based on work including 327 drill holes on the property. Mineralization is open to expansion. The price of tungsten has increased significantly in recent years and is currently approximately $33 per kilogram of contained tungsten trioxide. (These resources are historic in nature, prepared by Union Carbide Corp. in 1980 and are considered relevant. However, a qualified person has not done sufficient work to classify the historical estimates as current mineral resources and the Company is not considering the historical estimates as current mineral resources.)
The Covas property is located about 100 kilometres north of Porto, Portugal's second largest city. Blackheath holds the property under an option from Avrupa Minerals Ltd. to earn up to an 85% interest in a joint venture in the project, after incurring minimum exploration expenditures of EUR1 million in two stages to earn a 70% interest followed by completion of a prefeasibility study to earn the additional 15% interest.
