Blackheath Reports 62m of 0.18% WO3 at Borralha Tungsten Project
July 23, 2014 (Source: Marketwired) — Blackheath Resources Inc. (TSX VENTURE: BHR) (FRANKFURT: 04B) (“Blackheath”) is pleased to report results from the first drill hole to intersect the Santa Helena Breccia at the Borralha Tungsten Project in northern Portugal. The current drill program is designed to test the size, geological structures and continuity of the tungsten-bearing quartz veins and to further gauge the grade of the tungsten-bearing breccia body.
Assay intervals for the diamond drill hole BO-05/14 are:
- 0.18% WO3 over 62 metres (from 55m to 117m) including
- 0.24% WO3 over 29 metres (from 88m to 117m)
Five diamond drill holes have now been completed and one of the drill holes, located near the centre and designed to test the depth of the Santa Helena Breccia, was stopped at 200 metres. The full 200 metres started and ended within the mineralized breccia body but as yet assays have not been received. Two holes were drilled to the south of the Santa Helena Breccia and encountered a tonalitic granite zone with narrow intervals of wolframite that appear to be sub-economic.
“We are encouraged and excited about the first drill result from the Santa Helena Breccia at Borralha,” said James Robertson, CEO of Blackheath Resources. “Tungsten mineralization is extensively evident over the breccia zone on surface and this initial drill result confirms it continues at depth. We look forward to further results at Borralha.”
Blackheath holds the rights to a 100% interest in the Borralha Tungsten Project, which is the largest past-producing tungsten mine in Portugal. The mine closed in 1985 as a result of world wide low tungsten prices. Tungsten price is now significantly higher at around US$37 per kilogram of WO3 (tungsten trioxide). The Santa Helena Breccia zone has not been previously drilled and is over 500 metres in length, 200 metres wide at the south end and open to an unknown depth.
Trenching results from within the northern section of the Santa Helena Breccia

Two trenches were excavated across the northern portion of the surface of the Santa Helena Breccia with results including 45 metres at 0.216% WO3 as shown:
|Sample||From (m)||To (m)||Width (m.)||WO3 %*|
|Trench T8 (all samples)||0||100||100||0.114|
|Trench T9 (all samples)||0||80||80||0.036|
Results were encouraging and consistent with the previous trenching done in the southern portion of the breccia. Results from the previous trenching campaign included 20 metres with a grade of 0.33 % WO3 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.
