ABSTRACT:Copperstone Resources AB (Nasdaq First North “COPP B”) (“Copperstone” or the “Company”) is pleased to announce assay results from three (3) deep drill holes totaling 2,611m that have now been completed on the 100% owned Svartliden-Eva exploration target in Norrbotten county, Sweden. Drilling work commenced 1st February 2017 and was completed on 23rd May 2017, followed by a period for final laboratory analyses. The objective of the three drill holes was to test for deeper mineralization of hydrothermal origin below the existing large drill hole data sets around Svartliden and Eva (106 inclined collars, 14,830m, maximum 300m drilled length), and to gain insights into the style, possible continuity and origins of significant shallow intercepts of copper-gold-zinc mineralization at this location. The geological information at greater depth allows better understanding of the broader genetic model, and supports future deep geophysical modelling and drill targeting. A single drill site location was chosen central to the two areas, with COS17353 (hole 1) collared at -70 degrees dip to the NNE to 1166m, COS17354 (hole 2) collared at -70 degrees to the SSW to 572m, and COS17355 (hole 3) collared near vertical to 872.55m. “Our first deep drilling campaign has proven that high grade vein-style sulphide-hosted Cu-Zn mineralization does indeed extend well below both the Svartliden and Eva areas. We have found veins with high grade zinc and even deeper copper-rich veins. In addition, shallow low grade gold mineralization is hosted in intensely silicified rock, with some decent higher grade zones.” comments Chris McKnight, Chief Geologist and Director of Copperstone.
