Blackheath Resources Inc. (TSXV:BHR,FWB:04B) completed a preliminary trenching program at its Borralha Tungsten Project in Portugal. The program confirmed significant amounts of tungsten at surface in the Santa Helena Breccia, both in areas that were previously mined and also in new discovery zones. Highlights include 20 metres with a grade of 0.33 % WO3 (tungsten trioxide), including 5 metres of 1.09% WO3.
As quoted in the press release:
Six trenches were excavated across the southern portion of the surface of the Santa Helena Breccia zone at Borralha. Results are encouraging and included 20 metres with a grade of 0.33 % WO3 (tungsten trioxide) including 5 metres of 1.09% WO3. Two geological test holes were also drilled into the sub-horizontal quartz-wolframite (tungsten) vein system (see Figure 1). Other work included mapping and topographic surveys, grid preparation and geochemical sampling.
Blackheath Resources Inc. President and CEO, James Robertson, said:
We are greatly encouraged by the results of this preliminary exploration program at Borralha. The potential of the Santa Helena Breccia zone, surrounding and including the partially mined historic open pits, could be demonstrated in a short time with a surface drill program. We are now at a stage that we can confidently proceed with drill target locations. The exact magnitude of Borralha will be realized over time, but we can now start to see why Borralha was such an important and prolific tungsten mine.
