Copperstone Resources: Technical report Svartliden and last preparations for
deep core drillings
Copperstone Resources AB (Copperstone or the Company) hereby announces the
complete technical report regarding the modelling of the alteration zones at
Svartliden. The key findings support the hypothesis that has earlier been
verified and the hypothesis is now further strengthened subsequent to
identified minerals (e.g. sericite and pyrrhotite) in drill cores that have
been verified through thin section analysis.
During the past three months, a detailed examination of 56 drill holes
(approximately 7,000m of core) from the Svartliden area has been completed by
an international team of geologists. During this period analysis of structural
geological data, phyllic alteration patterns, and the identification and
mapping of phreato-magmatic breccia bodies has been carried out. Detailed 3D
modelling work (please see the complete report attached to this press release)
has formed a number of common vectors that indicate the potential for blind
porphyry-style Cu-Au-Zn mineralization at depth.
At Svartliden, mineralization is hosted mainly in a series of
pyrrhotite-chalcopyrite veins. It is postulated that fluids (liquid/gas at
high temperatures and pressures) were trapped below a phyllic alteration cap
associated with the rise of a granite-like intrusive stock. Dynamic
brecciation resulted in development of diatreme breccia and the subsequent
dispersion of some mineralization out into the unaltered country rock. On-going
mapping and modelling from the adjacent Eva gold-zinc rich massive pyrite
mineralization bodies south of Svartliden has complimented this dynamic model.
At present it is expected, as from February, to commence a core drilling
campaign including three bore holes, each of which at approx. 800 metres. The
first hole aims at the expected broad and rich ore zone, beneath the assumed
cap rock of the phyllic zone and is planned to be drilled to the northnortheast
(NNE). The second hole is planned to be drilled from Svartliden into and
beneath EVA southsouthwest (SSW). Localization and direction of the third hole
will be decided given the experience of the initial holes. Drilling work will
be complimented with downhole optical and geophysical studies. After the
drilling at Svartliden, the Company plans similar analyses and drillings to be
executed at Granliden Hill and Granliden South, due to similar characteristics,
such as the size of mineralisation as well as high grades in drill cores at
depth.
”It is our understanding that the Copperstone project, with Svartliden/EVA
first out, is the most interesting mining exploration project currently under
way in the Nordic region. The Company has, together with its international team
of geologists, completed a significant amount of work in order to secure the
correctness of the hypothesis, in order to facilitate a discovery of a blind
copper gold porphyry mineralisation. We are, including related parties and our
investors, ready to commence exploration drillings that Norrbotten and Sweden
could benefit from during a very long period of time, and create headlines
outside the Swedish borders,” comments Copperstone CEO Per Storm.
