CARBO DRILL CORE DISPLAYS ABUNDANT REE MINERALS
Canadian International Mineral Inc. and Commerce Resources Corp. have provided an update on the current and continuing diamond drill program on the Carbo rare earth
element (REE) property. CIN is earning a 75-per-cent interest in the property
from Commerce Resources Corp., and is meeting all conditions of
the agreement to earn the interest. Drilling is currently on the
eighth diamond drill hole. Total core as of late Nov. 6 was
1,226 metres. Drilling will continue until weather dictates the end of
safe and cost-effective working conditions.
Core is flown out daily to a staging area about one kilometre from the drill site
and trucked to a secure core processing and storage facility in Prince
George. There it is logged and sawn by Mackevoy Geosciences Ltd.
personnel and shipped to ALS Chemex via DHL. Samples are pulverized,
split and analyzed using gold fire assay ICP-AES finish, whole
rock ICP-AES and 38-element fusion ICP-MS (includes all REEs). They were also analyzed using trace
lead and zinc packages. No assays have been received, and first results
are anticipated in two weeks.
The Carbo property comprises seven claims totalling an area of 2,778.63
hectares and is accessible by all-weather gravel roads. It is located
in the emerging Wicheeda REE carbonatite camp approximately 80 km northeast of Prince George on the western margin of the Rocky
Mountain trench, a major continental geologic feature which is now
recognized as the locus of numerous potentially economic concentrations
of rare metals. Much of this terrain has seen very little exploration
incorporating current models and modern technology. It is adjacent to
and contiguous with Spectrum Mining's Wicheeda rare metals discovery,
as described in BCGS assessment report No. 30873. The Carbo drill
targets are within 900 metres of Spectrum's 2009 drilling.
The region has garnered significant attention due to the discovery of
significant REE mineralization associated with the Wicheeda
carbonatite-syenite complex. The Carbo property covers in excess of six km strike length of the complex, which is manifested as an elongate,
northwest-to-southeast-trending geophysical anomaly.
A geological synopsis has been provided by Allison Brand, MSc, Mackevoy
Geoscience Ltd., as follows.
The area currently undergoing diamond drilling corresponds to a distinct
airborne geophysical anomaly and coincident soil sample assays from several locations with
anomalous rare earth elements and pathfinders. Diamond drill core from the initial five
holes has been examined, and all holes intersect sections of carbonatite, associated alkaline
dikes and metasomatic alteration. Assays are expected shortly from all drill core in the first two drill
holes.
Carbonatite intersections can be thin to several tens of metres in
thickness, and are generally planar and parallel to host rock (siltstone/phyllite) fabric, which is
consistently subvertical. Occasionally the carbonatite is transitional to some of the alteration
styles or occurs as crosscutting dikes or veins. Interfingered layering and breccia matrix infill of
fine-grained, carbonatite material occurs near or at carbonatite contacts. Carbonatite is typically a
combination of crystalline calcite, dolomite, and/or ankerite, accompanied by a variety of rare element
accessory minerals. The host rocks around the intrusive are altered in a variety of modes to varying
degrees. The alteration variably consists of bleaching, hornfelsing, pyritization,
Na-K-carbonate metasomatic halo and flooding of grey-blue feldspar-feldspathoid proximal to carbonatite. In
addition, carbonate-bearing alkaline dikes that crosscut the host rocks are sulphide-rich
(sphalerite, pyrite, pyrrhotite and galena).
Several research samples were chosen to elucidate the composition and
identities of accessory minerals in carbonatite and its associated alteration zones. These
samples were investigated via scanning electron microscopy (SEM) by Prof. Lee Groat, Dr. Jim Evans
and Dr. Leo Millonig of the University of British Columbia's mineralogical research group. Most
significantly, REE-carbonate phases were identified in carbonatite and likely correspond to a
combination of bastnae-sitesynchysite-parisite. Where concentrations of this mineral assemblage were reported,
they were noted to be up to 50 per cent of the interval by mode. Sphalerite, strontianite
(strontium carbonate), an unknown Ni-Fe-Cr oxide, barite, columbite and Nb-rich rutile
were also identified. Significant sulphide is also present in deeper carbonatite intervals. Phases identified in core include phalerite, galena, pyrite, pyrrhotite and chalcopyrite. The SEM
investigation also confirmed the presence of feldspathoid and feldspar phases in alteration zones.
The style of mineralization thus far observed is consistent with known
occurrences of REE mineralization within the region. As previously
stated, all core from the first two holes is currently being assayed.
CIN and CCE are proud to be sponsors of the upcoming International
Workshop on the Geology of Rare Metals in Victoria on Nov. 9 and 10,
organized by the British Columbia Geological Survey, Geological Survey
of Canada and the Pacific Section of the Geological Association of
Canada. The companies are also honoured that five of their consultants or members of
CIN's advisory board are presenting or authored papers for the workshop.
They are Prof. Groat and David Turner, MSc
(University of B.C., Mackevoy Geoscience Ltd.); Prof. Anton
Chakhouradian, PhD, and Ryan Kressell, MSc (University of Manitoba);
and Prof. Roger Mitchell, PhD, (Lakehead University).
Select sections of core from the current drilling program at Carbo are
being sent out for further study, and pictures of mineralized core are
available for viewing on the company's website.
