Copperstone Resources: Svartliden is most likely part of a large hydrothermal
alteration system

Copperstone Resources AB (the Company or Copperstone) is publishing an
operational update for Svartliden. During the last months, an international
team of geologists have been evaluating a hydrothermal alteration halo that has
been identified at Svartliden and is central to the working hypothesis that
Svartliden/Eva is prospective for discovery of possible copper-gold
porphyry-style mineralization. These observations are significant and
constitute necessary, but not sufficient evidence to find blind porphyry-type
deposits with depth. 

During the period the following tasks have been carried out for the Svartliden

  -- Approximately 7000m of drill core at Svartliden has been re-mapped.
  -- Compilation of a comprehensive database for the entire project area. 
  -- 2D and 3D analysis of the geology and alteration types.
  -- Discussions with another international geological expert, Dr Chris Carlon
     has been carried out.
  -- Mineralogical study of core samples, including x-ray diffraction
  -- Design of drill holes that will interrogate the potential for discovery.
  -- Work is ongoing and is expected to be concluded this year.

Preliminary mapping and modelling work indicates that the Svartliden area is
indeed underlain by a NE-SW trending boundary between propyllitic and more
intensively brecciated phyllic alteration styles.  This trend is coincident
with the general strike of the sulphide vein swarms found at shallow depth
(10-200m) around Svartliden.  Mapping of phreato-magmatic breccia bodies also
indicates a similar trend and dip.  Vector analysis of the modelling suggests
that the causative stock is located at depth below the southern area of the
Svartliden concession. 

It is believed that the Svartliden base metal mineralization is leakage from
within a large hydrothermal alteration halo developed around a blind magmatic
emplacement.  This halo effect is also envisaged to include the more gold-rich
mineralization at Eva. 

“It is very satisfying that more and more pieces come together. So far,
everything points to Svartliden/Eva being a hydrothermal alteration system. The
structured work that has been carried out has led to a re-evaluation of the
geological model – which in itself is ground breaking – and can now
convincingly explain the potential ore forming process of the Copperstone area
specifically around Svartliden/Eva. We also want to highlight the innovative
nature of the developing work the Company has been carrying out over the past
few years. Thanks to our financial backers, the Company has been able to engage
international geological competence, use unique OPTV-techniques and use
international competence formineralogical studies. Through this, Copperstone
has reached the highest point in the Company’s history and is ready for a
successful exploration this winter.” Says Copperstone CEO Per Storm
