St. Juliens Copper

St. Juliens Copper Exploration Project

The St. Julien’s Project is located on the eastern shores of the Great Northern Peninsula in Newfoundland, south of the community of St. Anthony. The claims were originally optioned in 2008 and since that time the ground position has been increased. To date the ground position consists of greater than 570 claims covering 14,250 hectares. The entire project area is near tidewater.

Phase 1 of exploration consisted of prospecting and trenching on the original St. Julien’s copper showing, named “Copper Cod” and was carried out during 2008. The original showing was an old shaft from the turn of the century into a copper bearing quartz vein. Channel samples from the shaft area revealed assays up to 15.8% copper (Cu). Numerous surface copper showings in quartz veins have been discovered in the field.

To date more than 40 quartz veins has been uncovered. Channel samples of the copper-bearing quartz veins on the property have revealed numerous high grade assays with the highest values being 22.5% Cu. Veins had widths up to 2.5 metres and lengths up to 140 metres. All mineralization is associated with hydrothermal activity. A NI 43-101 compliant technical report has been completed for the Phase 1 work at the St, Julien's Project.

A Phase 2 program consisted of a geophysical airborne VTEM survey flown by Geotech Inc. during November of 2008. This work generated electro-magnetic maps and magnetic maps for a portion of the St. Julien’s Project.  see geophysical maps

The airborne geophysics has been further interpreted by an independent consultant. This report suggested several anomalous targets at the Copper Cod and Fischot Island areas. The targets were ground truthed during the Phase 3 program.

The Phase 3 program of exploration on the St. Julien’s project consisted of an 11 person geological and prospecting team mapping, geochemically sampling and prospecting 55 square kilometers of the project. At present the maps and reports for this work is being completed. This phase of exploration allowed for a better understanding of the geology of the property as well as defined possible drill targets. The exploration work was able to extend copper mineralization 2500 metres north of the original Copper Cod Showing (old shaft), make  a new zinc and silver showing in the marble pit area and resulted the new copper discoveries at Fichot Island.

Fischot Island is a group of islands that are geologically represented as a mafic volcanic suite of rocks with several large gabbros intrusions. The volcanic rocks to the north contain a large stockwork system of quartz veining. The quartz veins are generally brecciated and carry pebble to cobble size chalcopyrite pieces. The mafic volcanic rocks are highly altered with chlorite, epidote and lesser amounts of carbonate. The northern island, Northwest Island, contains the bulk of the copper mineralization, as well as Frommy Island. The present work has indentified two zones of copper sulphide mineralization. Copper mineralization is generally situated in the quartz veins but is also found in associated shear zones and to a lesser extent in the host rock.

The main zone of copper mineralization covers an area of 1400 metres by 700 metres on surface and has a general ovoid shape. Copper mineralization is generally associated with the brecciated stockwork quartz veins and associated shear zones. Veins have been noted up to 15 metres in width but average around 10 centimetres. Strike lengths are commonly over 100 metres. Associated shear zones are generally 10 metres wide and contain disseminated chalcopyrite and pyrite. Surface sampling has returned copper values in the range of 0.6% to 5%. Several samples outside of the main zone of mineralization assayed 0.1% to 0.5% copper and forms a lower grade narrow envelope of mineralization.

The northern zone of mineralization is located in the northern portion of the island chain. This zone is a linear trend that extends for 2100 metres with a width of 100 to 125 metres. Copper mineralization is predominantly hosted in the brecciated quartz veins as pebbles and cobbles of chalcopyrite but also as disseminated sulphides in shear zones. Assays ranged from 0.6% to 2% copper. This zone of mineralization has a lower grade copper halo of mineralization with widths of 20 to 30 metres on either side of the trend. The lower grade copper assayed between 0.13% and 0.5% copper.

Phase 4 of exploration will be a diamond drill program to be carried out during the winter of 2009. Numerous drill targets have been identified. A proposal has been planned for a 4000 meter program.
