COPPERSTONE RESOURCES: DISCOVERY OF PORPHYRY-STYLE Cu-Au MINERALIZATION AT
SVARTLIDEN-EVA

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
immediately 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.
