Blackheath Commences Drill Program on Santa Helena Breccia at
Borralha
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Apr 15, 2014) -
Blackheath Resources Inc. (TSX-VENTURE:BHR) (FRANKFURT:04B)
("Blackheath) is pleased to announce the first ever diamond drill
program at the Santa Helena Breccia located within the historic
Borralha Tungsten Project, in northern Portugal. Blackheath holds
the rights to a 100% interest in the Borralha Tungsten Project,
which is the largest past-producing tungsten mine in Portugal. The
program will include up to 8 drill holes totalling up to 1,300
metres. The drill program is designed to test the size, geological
structures and continuity of tungsten-bearing quartz-veins and to
further gauge the grade of the tungsten-bearing breccia body.
This is the first stage of a potential larger drilling program
and is based on previous work on the project including 6 trenches
that confirmed significant amounts of tungsten at surface. Theses
trenches were excavated across the southern portion of the surface
of the Santa Helena Breccia. Results were encouraging and included
20 metres with a grade of 0.33 % WO3 (tungsten trioxide) including
5 metres of 1.09% WO3 within a trench of 100 metres averaging 0.13%
WO3. Mineralization of disseminated wolframite occurred in all of
the trenches and had widths and grades of potential economic
interest, subject to further work. (See news release dated
September 16, 2013 for details)

The program is designed to test the target zones and the
tungsten-bearing veins in the Santa Helena Breccia. The first drill
holes of the program will concentrate on the southern portion of
the breccia in line with the previously completed channel sampling.
The program is expected to be completed within approximately 12
weeks.

"We are pleased to commence the drilling program on the Santa
Helena Breccia at Borralha," said James Robertson, President &
CEO of Blackheath Resources. "Evidence of tungsten mineralization
disseminated in the breccia and the numerous high-grade
tungsten-bearing quartz-veins throughout the zone suggest the
opportunity for a large and significant deposit that can be rapidly
confirmed. Our exploration objective is to confirm the grade of the
tungsten-bearing breccia."
The Santa Helena Breccia zone at Borralha has been partially
mined by small, shallow open pits in areas of more extensive
tungsten-bearing quartz veins. Other tungsten veins have been
scavenged over the years, often by "apanhistas" or illegal miners,
and all mining ceased in 1985 as a result of world-wide low
tungsten prices. The breccia body is over 500 metres in length, 200
metres wide at the south end and open to an unknown depth.
The Borralha concession is located 60 km northeast of the major
northern city of Porto and covers 127.5 km2 over several past
producing zones. Tungsten occurred in numerous vertical and
sub-horizontal veins as well as two breccia bodies, of which the
Santa Helena breccia is the larger. Mining continued almost
uninterrupted from 1903 to 1985, by French, British and German
companies with two standstill periods from mid 1944 to late 1946,
imposed by law, and from 1958 to late 1962. Production ceased in
1985 when tungsten prices dropped to sub-economic levels. The total
production of wolframite and scheelite (tungsten minerals)
concentrates from 1904 until the closing of Borralha, from
underground and open pit sources, has been estimated at about
18,500 tonnes, although this number is approximate and may be
substantially less than the true value.
