John Lee bringt es auf den Punkt: ...
die
vorläufigen Ergebnisse der Bohrungen und wirtschaftlichen Studien
im Jahr 2012 helfen das Risiko zu vermindern und den Ausbau des
Wellgreen-Projektes Richtung Machbarkeit voranzutreiben.

Prophecy Platinum Corporation announced the results of its
preliminary metallurgical tests for its Wellgreen Ni, Cu and PGE
project located in the southwest of Canada's Yukon Territory.
This Phase I of an extensive metallurgical program focuses on
producing a bulk Ni-Cu-PGE-Au concentrate from disseminated
sulphide, ultramafic mineralized rocks that comprise the majority
of Wellgreen's National Instrument 43-101 resource:
To date, a total of 41 rougher and cleaner tests and 4 locked cycle
flotation tests have been conducted and completed at SGS
Laboratories in Vancouver, British Columbia. Results indicate that
a bulk concentrate of 5.6% nickel, 6.0% copper, 3.5 gram per tonne
platinum, 6.3 gram per tonne palladium and 0.5 gram per tonne gold
can be produced.
A150 kilogram composite blend of the prevalent host mineralized
rocks was crushed to a 10 mesh size and used as the sample for
testing. A calculated head feed grade of 0.45% nickel, 0.35%
copper, 0.42 gram per tonne platinum and 0.46 gram per tonne
palladium was tested. Conventional flotation conditions were used
to produce a concentrate with emphasis on base metal recoveries
from locked cycle testing.
While this preliminary phase focused on metal recovery from
Wellgreen's mineralization of typical representative grade, an
additional test was conducted using material with a higher
calculated head feed grade of 0.83% nickel, 0.55% copper, 0.57 gram
per tonne platinum, 0.57 gram per tonne palladium and 0.08 gram per
tonne Au. LCT-4 produced a concentrate containing 8.2% nickel, 6.5%
copper, 2.9 gram per tonne platinum, 5.6 gram per tonne palladium
and 0.6 gram per tonne gold. These results represent recoveries of
73% nickel, 88% copper, 38% platinum, 73% palladium and 62%
gold.
The 41 batch tests were designed to test different flowsheet and
reagent combinations. Conditions for the reported test LCT-3
include Xanthate, CMC, guar gum and CuSO4. Test conditions for
LCT-4 utilized the same reagents as LCT-3 except for the exclusion
of CuSO4. LCT-3 and LCT-4 demonstrate that metals can be recovered
from varied Wellgreen mineralization through substantially
identical flowsheets and common reagents.
Mr John Lee chairman of Prophecy said that "We
are delighted with these preliminary results. The follow-up met
studies along with our infill drilling, expansion drilling, and
preliminary economic studies in 2012 will continue to de risk our
100% owned Wellgreen project and advance this highly unique asset
towards feasibility."
