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. (See

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. (See
drill hole location map for Castelo.)

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.
