Blackheath Resources Inc. announced that further exploration is underway on its tungsten projects in northern Portugal. Work includes diamond drill programs on the Borralha and Covas projects. At Borralha, Portugal's past-producing tungsten mine, two drill holes are underway to provide further confirmation of the extent of tungsten (wolframite) near-surface mineralisation in the area of the Santa Helena Breccia, a historic open pit. Past drilling by the Company provided encouraging results including a 118 metre intersection in Hole BO 8A assaying 0.29% WO 3 (57m to 175m). The price of tungsten is currently approximately USD 280 per metric tonne unit (MTU) (10kg) of contained tungsten trioxide (WO3) equivalent to USD 28 per kilogram. Internal studies of the Borralha project have given encouragement to carry out further assessment drilling, initial scoping studies and preliminary environmental work before proceeding with any resource estimate. 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. Blackheath completed successful diamond drilling programmes in the Santa Helena Breccia in 2014 and 2015. At the Covas project, which is a past-producing open pit and shallow underground mine, the Company has previously announced an independent maiden resource estimate compliant with NI 43-101. The estimate is based on the results of 326 drill holes on the property. Current work is focussed on the hypothesis of a previously untested bulk tonnage tungsten target possibly indicated by coincident geophysical and geochemical anomalies where deeper drilling is presently underway.
