Mapping and sampling over the Prainelas area, approximately 1.5 square kilometres in size, has so far located at least 12 waste dumps from previous workings and at least 30 tungsten-bearing quartz veins over a distance of 900 metres.
A single grab sample taken from one of the tungsten-bearing veins assayed 6.60% WO3or 66 kg/tonne. Six grab samples were taken from six of the waste dumps and averaged 0.68% WO3 (tungsten trioxide) or 6.8 kg/tonne, ranging from 1.43% to 0.18% WO3 with additional tin values averaging 0.11% Sn. (These must be considered to be preliminary selected samples, and as such, may not be representative of average values for each area.)
"We are delighted with the early encouraging results from our reconnaissance work at Vale das Gatas," said James Robertson, P.Eng., President & CEO of Blackheath Resources. "This mine is the second-largest past producer of tungsten in Portugal after closing in 1986 because of depressed tungsten prices. Tungsten price is now around $38/kg and we look forward to carrying out further work including diamond drilling at Vale das Gatas in early 2014."
The Company also reports the resignation of Marshall Farris from the board of directors of Blackheath. Mr. Farris was a founding director of the Company and leaves to pursue other business interests. We wish him every success in his future activities.
