Overview | Location: | Nunavut, 260 kilometres northwest of Churchill, Manitoba and 120 kilometres west of Arviat, in the Edehon Lake Area, South Kivalliq. The project lies within a basin of virtually unexplored Proterozoic rock. Access is provided by fixed-wing aircraft or helicopter. | | Highlights & Potential for Discovery: | Regionally extensive iron-formation appears to mark the boundary between basal, volcanic-dominated and upper, sedimentary dominated rock sequences. The iron formation has not yet been evaluated for its economic potential. Gold values of up to 18.7 grams per tonne, copper values of up to 1.49% and uranium values of up to 22.1 lbs of U3O8 per tonne have been obtained from grab samples of locally-derived frost-heave boulders. Regional airborne electromagnetic and magnetic surveying conducted by Tri Origin has delineated a number of important anomalies and drill targets have been prioritized in the vicinity of known metal occurrences. | | Description of Asset: | The project comprises 9 claims totalling 7,942 hectares in 4 non-contiguous groups 100% owned by Tri Origin. The claims are subject to a 2% net smelter return royalty on base and precious metal production and a 2% net production royalty on diamond production payable to BHP Billiton Plc.
| | Reason for Selection: | Proterozoic rocks of similar style and age elsewhere in the Canadian Shield host large deposits of uranium, gold, copper and nickel and on other continents, host some of the largest metal producing districts in the world. Although essentially unexplored, the “Keewatin” area was identified as having potential to host major ore deposits during initial reconnaissance of the area. Copper, gold and uranium occurrences and iron formation now identified in these rocks confirm the Company’s exploration rational and justify additional exploration. | | Planned Exploration: | At June 30, 2011, the Company had no immediate plans for exploration due to the property’s remote location and high logistical cost of mobilizing a drill to the area. A joint venture or option arrangement with another Nunavut-based explorer may be considered in the future. |
Technical information
| Project and Regional Synopsis: | The Keewatin property represents an excellent opportunity to explore for gold and base metals with drill-ready targets in a very prospective and virtually unexplored terrain. BHP Billiton Plc., the worlds largest diversified mining company, identified the potential of the area through their Canada-wide regional exploration efforts. It subsequently approached Tri Origin regarding its interest in jointly exploring for giant deposits similar to that of the Broken Hill Mining district in NSW, Australia, one of the worlds largest producers of zinc, lead and silver.
Tri Origin’s work has identified geologic “marker” units of carbonate and quartzite near the central part of the basin. Similar rock sequences elsewhere in the world host very large stratabound deposits of copper, zinc, gold and uranium. Exploration work is in its early stages however copper, gold and uranium occurrences have been identified in proximity to these marker units.
In addition, iron formation has been identified in outcrop and traced regionally using airborne magnetic data. The iron formation has not been evaluated for its economic potential. | | Results to Date: | Tri Origin completed preliminary field examinations to assess the property in 2003, 2004 and 2005. Tri Origin examined selected airborne "Megatem" electromagnetic anomaly sites for mineralization, alteration and other features indicative of large "Sedex-type" base metal deposits. In addition, Tri Origins field examination returned assay values from samples of boulders of up to 18.7 grams of gold per tonne and up to 4.87 grams of gold per tonne in grab samples from outcrop.
In April of 2005, Aeroquest Limited of Mississauga, Ontario completed an airborne electromagnetic and magnetic survey utilizing the AeroTEM II System. Aero TEM II provided important refinement of existing geophysical data and further defined locations selected for drilling. In 2006, a small, portable drill-rig was mobilized to test targets but was not successful in reaching target depths. A drill program of 5 short holes was completed in 2007. This program was also largely unsuccessful due to extensive boulder and overburden cover however did result in intersections returning anomalous values in gold, copper and uranium at 3 targets.
A large number of preliminary targets remain unexplained and further ground surveying and drilling is warranted. | | Technical Reports: | | | Links to News Releases: | |
