COPPERSTONE RESOURCES: Copper-gold porphyry-style mineralization at Svartliden.

Copperstone Resources AB (below ”Copperstone” or ”the Company”) announced the
discovery of a copper-gold porphyry-style mineralsation of the southern part of
the Copperstone project at Svartliden/Eva on March 17th. This is an update of
that announcement. 

Based on a predictive hypothesis for targeting blind porphyry-style Cu-Au
mineralization at Svartliden, the Company is very excited to announce that the
first deep drill hole has indeed encountered a significant intercept of
chalcopyrite-arsenopyrite-bornite mineralization over a 90m length from
720-810m downhole. The true with of the mineralization is not known at present.
Prior to the intercept, the drill hole has also encountered thick phyllic
alteration with stronger pyrite halos with depth, thus complimenting the large
alteration model identified in recent studies. The drill hole is at 887m and
continues to encounter veinlets of copper mineralization within a possible
causative felsic stock. A more detailed description including pictures can be
found in the appendix and on www.copperstone.se. 

All indications are that the main column of mineralization may lie to the west
of this drill hole trace. Beyond the mineralized zone (MMZ in the appendix),
obvious quartz-feldspar porphyry has been found, and this may be the causative
stock. 

"In my opinion, this is the most exciting exploration play of my career. The
geological architecture of this geographical region suggests good prospectivity
for discovery of new porphyry-style cu-au hydrothermal systems. Our model
works, it was a big ask, and no doubt we have discovered something very
exciting. New insights and shear determination have yielded the beginnings of a
new chapter in the history of mineral exploration in Sweden. There is little
else on this scale for greenfield exploration in the region." Says lead project
geologist Chris McKnight. 

“This is very satisfying and most likely a historic even in Swedish
exploration. We have with perseverance and extensive support from shareholders
and stakeholders achieved something remarkable: to discover what we believe is
a new geological system in the vicinity of the Skellefte field which, in time,
can result in a new big mining area. Now continued drilling, assaying of
valuable metals such a copper, zinc, silver and gold, evaluation and further
planning of upcoming work will follow. As we have verified the hypothesis at
Svartliden, the northern part of the project, Granliden, which is based on
available information from a large amount of drill holes and which shows the
same characteristica, will be investigated from the same angle. Based on all
available information, we are considering postponing the application work for
an exploitation concession and Granliden in favour of investigating the area
further We will return with more information as soon as we have verified
further information.” says Copperstone CEO Per Storm in a comment.
