Wedeene Project
Location
Logistics and other economic considerations for the Wedeene River project are excellent. An extensive network of logging roads provides access to most eastern portions of the property. The city centre for Kitimat, a tidewater port, is only 1 km from the southern portion of the property. A major rail line passes through the eastern part of the property and a hydro-electric line comes within 6 km of the present drilling.
Geology and Mineralization
Most of the claim area is underlain by steeply dipping volcanic rocks of uncertain age which, along the western margin of the claim area, are intruded by granitic rocks of the Cretaceous to Tertiary Coast Intrusions. Near the contact volcanic units are partly to completely recrystallized and cut by numerous dykes, sills and irregular masses of fine-to coarse-grained diorite.
Hydrothermal alteration consisting of sericite, chlorite and possibly clay minerals has affected the host Triassic volcanics and Jurassic diorites to varying degrees. Pyritic zones which contain 5-7% pyrite and local chalcopyrite are associated with strong local "potassic" and pervasive "phyllic" alteration zones intruded by strongly epidote altered dykes. The mineralization contains disseminations, fine veinlets and massive veins of pyrite and/or chalcopyrite. Typically, the altered rocks are bleached to a pale grey-cream colour. Silicification consisting of closely spaced veinlets or flooding occurs throughout the mineralized zones. The sulphide minerals predominantly consist of pyrite and or chalcopyrite, although pyrrhotite is present in drill core. Typically, the pyrite and chalcopyrite occur as finely disseminated grains, which are less than l mm in diameter. Sulphide minerals in this habit generally attain concentrations of 1-10% pyrite and up to 2% chalcopyrite. To the southwest of the drilling, host rocks tend to be more heavily altered to sericite and less silicified than to the northeast.
The area of the above drilling has been along the west edge of a large magnetic low outlined in an airborne EM / Magnetic survey flown by the Company earlier this year. The magnetic lows are interpreted as areas that have undergone hydrothermal alteration where the magnetite in the rocks is altered to other iron minerals, namely pyrite. Associated with the magnetic lows are numerous EM anomalies and coincident copper-gold anomalies outlined in regional government geochemical surveys. Based on the alteration and mineralization observed, the Company believes the drilling to date is at the west edge of a large porphyry copper-gold zone.
2010 Exploration Summary
Decade completed an electromagnetic geophysical survey on the property which was flown by helicopter. Using the data collected from the survey, the Company conducted an exploration program that included soil sampling,mapping and drilling.
A total of 16 holes tested an area of copper-gold mineralization near the headwaters of the Little Wedeene River. Analysis of the core shows that chalcopyrite is associated with pyritic zones in highly silicified rocks and assay data to date shows a strong correlation between copper and gold mineralization. The pyritic zones which contain 5-7% pyrite and local chalcopyrite are associated with silicification, strong local "potassic" and pervasive "phyllic" alteration zones intruded by strongly epidote altered dykes.
Assay results for some of the holes include 109 metres of 0.48% copper and 1.0 g/t gold in DDH-2010-J-1, 107 metres 0.45% copper and 0.80 g/t gold in DDH-2010-J-2 and 117 metres of 0.54% copper and 1.03 g/t gold in DDH-2010-J-7.
The Company is planning a future program consisting of MMI soil sampling, IP surveys and down hole IP to further define the limits of the copper-gold mineralized zone. The mineralization intersected on the Wedeene project is well located being only 14 kilometres from tide water at Kitimat, 6 kilometres from a major power line and 5 kilometres from a railway. Elevations at the property are low enough that exploration can occur year round.
