Polymetallic Shales
In 2008, to advance exploration and development of near-surface, metal-enriched black shales,
Dumont Nickel Inc. acquired a wholly owned 2536 square kilometre mineral property (SBH
property), located approximately 120 kilometres north of Fort McMurray in northeast Alberta.
The SBH property encompasses six 100 to 300 square kilometres of historical subproperties
(Buckton, Buckton South, Asphalt, Eaglenest, McIvor West and North Lily) previously studied for
metals by Tintina Mines Ltd., NSR Resources Inc., Alberta Geological Survey and the
Geological Survey of Canada.
No exploration work was completed on the SBH property in 2008; however, Dumont Nickel Inc.
compiled previous work in an NI-43-101 compliant technical report. Based on publicly available
information on extensive exploration work over the past 15 years and regional oil-gas drilling
databases, the SBH property is underlain by the near surface, flat-lying Late Cretaceous shales
of the Second White Speckled and Shaftesbury formations, which are locally enriched in Mo, Ni,
V, Zn, U, Cu, Co, Ag, Au, PGE and organic carbon.
The former unit (20-40 m thick) is mainly black shale interbedded with bentonitic seams,
contains up to 20% fine-grained sulphides (mostly FeS) and 3% to 29% organic carbon, and
represents Dumont Nickel Inc.’s primary exploration target. Based on the previous regional
outcrop and drillcore sampling, the Second White Speckled Formation contains up 0.13% V,
0.09% Zn, 0.04% Mo, 0.04% Ni, 0.027% U, 0.018% Cu, 3.6 g/t Ag and 3.4 g/t Au, in addition to
enriched Co, Cd and traces of PGE. At several locations, the black shales have elevated
sulphides and metal contents, identified as sedimentary exhalative (Sedex) in nature, with a
northward increase in thickness and frequency of bentonite seams. This indicates proximity to
the hydrothermal vents and the source of volcanic debris.
Dumont indicates two potential black shale-hosted polymetallic zones: Buckton and Asphalt.
Both the Buckton and Asphalt potential deposits are open in more than one direction for an
additional few kilometres. Based on the previous, extensive surface exploration, the Buckton
south property may represent a southern extension of the Buckton zone for a distance of 6 km.
Previous reconnaissance exploration on the McIvor west property identified surface Ni-Au-Zn
anomalies, as well as circular geophysical features consistent with similarly identified
polymetallic-enrichment zones elsewhere within the SBH property. The Alberta black shales
have many similarities with other black shale-hosted polymetallic deposits worldwide (e.g., Nick,
British Columbia, Canada, Talvivaara, Finland, and southern China).
