habe ich auch auf der Watchlist.
Immerhin musste der Chart erst einmal eine Verzwanzigfachung verdauen.
Der andere Grund dürfte in der noch immer fehlenden Ressourcenschätzung liegen.
Aus dem letzten Technical Report:
19 MINERAL RESOURCE AND RESERVE ESTIMATES A mineral
resource estimate meeting current Brazilian standards was
submitted to DNPM as part of the Mining Plan and
accepted. However, for the same reason that the VALE
mineral resource estimates (see discussion below) did not
meet the NI 43-101 standard, this resource does not meet
NI 43-101 requirements and cannot be published here.
Mineral deposits that contain pods of exceptionally high-
grade material are always difficult to assess.
Geostatistical modelling by independent consultants Mining
Associates Pty Ltd indicates that although the Serra
Pelada mineralization is not nuggety, and therefore on a
broad scale the variances are acceptable, in the high-
grade areas the variance is largely due to extreme short
scale geometric and spatial variability. A consequence of
this short scale geometric and grade variability is the
significant uncertainty with reporting of these
extremely high-grade resources. The block sizes in these
zones must be reduced, probably to 7-10m blocks. The
drilling by VALE was on 50m spaced lines. Colossus has to
date substantially closed the drill hole line spacing to
25m; however this is still too widely- spaced to allow a
resource estimate in a category better than inferred to
be calculated. Given the depth below surface, drill
intersections spaced close enough to allow definition of
block sizes of 10m or less can only be achieved by
accessing the mineralization from underground. This would
also facilitate drilling the flat to very shallow angle
holes necessary to determine true thicknesses in the
steep to vertically dipping high-grade zone in the fold
hinge. Any mineral resource estimate will need to
include the 40,000m of drilling carried out by VALE.
Colossus have re-assayed in excess of 2,000m of this core,
and re-logged all 40,000m, in order to assign a level of
to this historical work. The results suggest that the VALE
work was done to a high standard and that the analytical
results are reliable. The personnel responsible for
VALEs work were fully qualified under Brazilian law and
recognised by the Brazilian professional body. However,
Brazil is not represented on the Committee for Mineral
Reserves International Reporting Standards (CRIRSCO)
that sets the minimum standards being adopted in national
reporting codes worldwide with recommendations and
interpretive guidelines for the Public Reporting of
Exploration Results, Mineral Resources and Mineral
. Hence because the Brazilian personnel did not belong to
a professional association recognized by NI 43-101, there
could be some debate whether their work can be included
in a resource estimate, even if that estimate was done by
persons qualified under NI43-101. In Vidoros opinion,
Colossus has carried out sufficient work to verify that the
VALE results are reliable, and they should be included in
a resource assessment. However the decision as to how
this inclusion of historical data may qualify resource
categories under NI 43-101 would be made by the
independent Qualified Person responsible for resource
modelling. The drilling by VALE, supplemented by an
additional 11,000m in 40 cored hole
Damit wird für den Moment auch eine Bewertung schwierig,
die notwendigen Bohrungen können erst dann ökonomisch
durchgeführt werden, wenn der unterirdische Zugang zum
Deposit fertig ist. Ein anderes kritisches Problem ist das
Wasser, weswegen die ursprüngliche wilde Pit sich auch
selbst schloss. Wäre schade, wenn wie bei Cigar lake hier
der Stollen vollläuft. Aber gut, diese Unsicherheiten
bietet auch eine schöne Investitionsgelegenheit. Immerhin
will man 2013 produzieren, bis dahin müsste es also Schlag
auf Schlag gehen
Ach ja, CSI hat ca 80 Millionen Cash, das ist auch nicht schlecht.
