DIOS AU33 WEST AURIFEROUS TONALITE SAMPLES STRONGLY AFFECTED BY
HYDROTHERMAL POTASSIC ALTERATION
MONTREAL, QUEBEC, CANADA - DIOS EXPLORATION just received results
from a summary
petrographic examination of five auriferous samples from the Au33 West project.
The replacement textures described below as well as the abundance of matrix
microcline, in association with biotite and the quartz-microcline veins
indicate that the AU33 auriferous tonalite samples were strongly affected by
potassic alteration. This type of alteration further enhances the
porphyry gold type model looked for by DIOS (such potassic alteration is
typical of other gold deposits in the Abitibi area).
The
examined samples of this recent gold discovery with a petrographic microscope
show that they consist in a medium-grained (less than 4
mm) intrusive rock of tonalitic to granodioritic
composition that underwent major re-crystallization associated with a
pronounced potassic (K) replacement.
Some
of the samples show well-preserved primary textures, while others are injected
by quartz +/- microcline +/- carbonate veins. All samples show evidences of
multiple microcline replacements.
Biotite
is present within all samples, in fine-grained and of greenish (kaki)
colour. Observations suggest that biotite is partly associated with
potassic alteration that is mainly highlighted by the microcline abundance and
textures. It forms uniformly distributed granular aggregates that may
suggest replacement of primary ferromagnesian minerals. We also observed it in
inclusions within the feldspars, as well as locally associated to microcline at
the contact between quartz and feldspar-rich matrix.
The
Au33 gold diamond project, is located in the Opinaca area, James
Bay, Quebec, some 40
kilometers south of the world class
multi-million ounces Eleonore gold deposit. The whole report with
detailed photos will be available on our website.
