Copperstone Resources AB (below ”Copperstone” or ”the Company”) has the pleasure to announce the discovery of a copper-gold porphyry-style mineralisation of the southern part of the Copperstone project at Svartliden/Eva.

The drill programme includes three steeply dipping boreholes each to approximately 800 m length. Drilling of the first borehole commenced on 3rd February 2017 and is currently at a depth of 810m.

 Copperstone Resources is pleased to announce that an extensive quartz vein stockwork that appears to contain chalcopyrite, sphalerite, pyrrhotite, bornite and arsenopyrite mineralisation has been intercepted sporadically over an interval of approximately 85m between 725m and 810m, including thin post-mineralization dykes (vertical depth from approximately 650m onwards). From the top of rock, the drill hole encountered extensive phyllic-style alteration, including well developed pyrite halos. Sulphide mineralisation is still present at the current depth of the drill hole. Pyrite is largely absent in the zone of mineralisation.

At this stage true width of the mineralization is unknown. Sampling will start immedia1tely and first results will be available roughly within a month, depending on the laboratory turnaround time. Favourable results are anticipated based on the abundance of Cu-bearing sulphides.

Additional information will be provided early next week.
