Golden Eagle is situated at the southern end of the Tintina Gold Belt, which contains many intrusion-related gold deposits such as Pogo (Alaska), Fort Knox (Alaska), Dublin Gulch (Yukon) and the recent discovery at Underworld Resources' White Gold property near Dawson City (Yukon).
The property has the potential to host several deposit types, including bulk tonnage intrusion related deposits with associated skarn deposits, high-grade gold-silver vein-hosted deposits and volcanogenic massive sulphide (VMS) deposits. Thirteen separate mineralized zones have been identified to date over the property's 25-km long extent.
2005-2008 Exploration Programs
In 2008, 12 diamond drill holes totalling 2,406 metres were completed on the Tannis zone over a 250-metre strike length. Arsenopyrite (+pyrite) as disseminated, replacement-type and stringer mineralization within quartz veins was encountered in all eleven of the holes that reached target depth. The mineralized vein system was intersected in rhyolitic intrusive as well as in mafic volcanics of the Boundary Ranges Metamorphic Suite, and in granitic intrusive rocks at depth beneath the rhyolite. The presence of granitic intrusive at depth indicates a composite, volatile-rich intrusive system in this locale, which to-date has only been tested by shallow drilling.
Drill intersections indicate the highly variable nature of the quartz-sulphide veins both in terms of metal content and continuity along strike and at depth (Table 1). The best intersections returned 5.09 metres @ 7.93 g/t Au and 23.8 g/t Ag and 4.3 metres @ 2.05 g/t Au and 43.8 g/t Ag. The mineralized system is demonstrated to continue along a strike length of nearly 150 metres and to greater than 200 metres down dip in both the rhyolitic and granitic intrusions.
To date, only a limited portion of the Tannis zone has been drill tested as an intrusive-hosted gold target, with drilling largely confined to the younger rhyolitic intrusive. The possible roots of the vein system in the larger underlying granitic phase have not been targeted by any previous drill programs and deeper drilling in this area is required.
Tannis Zone 2005-2008 Significant Drill Results
During the 2008 program, mapping and prospecting in the vicinity of the Tannis zone further defined the quartz-sulphide vein system along a northwest trend nearly five kilometres in length. Taking into account similar mineral occurrences in other parts of the property, this length is extended to upwards of eight kilometres. In addition, a new drill target was identified on South Mountain, ~1.5 kilometres southeast of Tannis, where a cluster of nine gold and silver bearing veins were discovered within a ~100 x100 metre area. Highlights of the prospecting (124 rock samples collected) are presented in the Company's February 24, 2009 News Release.
Discussion and Deposit Model
The mineralization and the anomalies on the North prospect are related to two major structures, the Ben Fault and the Paddy Fault, and to an underlying granite-related gold system. The Ben Fault is a minimum of 3.6 kilometres in length and has never been drilled. The Paddy Fault is a minimum of 4.6 kilometres in length and has not been drilled apart from limited drilling (~250 metres) on the Skarn zone. This drilling intercepted significant gold mineralization but it did not test the underlying granite contact. Both faults both are possible splays of the Llewellyn fault zone, a regionally significant structure that cuts through the project area and has a strong correlation with the majority of mineral occurrences in the region.
A detailed high-resolution helicopter-borne magnetic, electromagnetic and radiometric survey was flown over the Golden Eagle project in 2004. This data was integrated with a recently completed compilation and reinterpretation of the technical data for the North prospect. Four geophysical maps are presented; for a brief explanation of each geophysical presentation, click here.
This northern portion of the Golden Eagle property is shown by the British Columbia Geological Survey's stream sediment sampling to contain exceptionally anomalous values in gold (to 1080 ppb), gold indicator metals (arsenic, antimony and mercury) and base metals (BCGS Bulletin 105). In file GF2003-9, the BCGS noted the volcano-sedimentary setting is analogous to that at Eskay Creek. Notably, the northwest trend of the quartz-sulphide vein occurrences on the property mirrors the trend of the Llewellyn fault zone.
2009 Exploration Program
In 2009, a reinterpretation of the technical data for the North prospect identified a number of new drill targets. A program of stream sediment sampling and prospecting followed, which helped to better define those targets and identify additional anomalous areas. A five-hole (506-metre) drill program commenced in October 2009 and successfully tested four previously un-drilled and widely spaced targets over an area of approximately 3.5 km². Results of the drilling are presented in the Company's February 17, 2010 News Release and in the following table.
North Prospect - 2009 Significant Drill Results
The results show the West Gully zone emerging as a large (2.5 km²), greenfield, gold target with potential for shallow mineralization. In addition, holes N0902/N0903/N0905 also appear to have identified a new, highly prospective, major gold bearing structure. As a result of data compilation and exploration that commenced in 2009, Troymet identified three primary targets for future diamond drilling:
2011 Exploration Program
The fall 2011 program conducted at the North prospect area included a 10.5 km pole-dipole induced polarization survey over the West Gully grid and the drilling of 6 holes totalling 867.2 metres. Drilling on the Skarn zone has identified a new bulk tonnage gold target. Results are presented in the Company's February 16, 2012 News Release and in the following table:
North Prospect - 2011 Significant Drill Results
Hole N11-06 was drilled on the Skarn zone to test an area of historic drilling from which no drill core exists. The hole intersected 36.45 metres grading 1.27 g/t gold in felsic volcanics. The upper portion of this gold intersection was also anomalous in silver, grading 4.05 g/t silver over 15.45 metres. The mineralization is associated with strong potassic alteration, carbonate alteration and silicification developed along the Paddy Fault. The mineralized zone is open southwards along the Paddy Fault towards the Catfish zone (~2.5 kilometres) and at depth. The potential for a wide zone(s) of gold mineralization was not recognized in the past. Troymet is modelling the new data and historical data in 3D to identify additional drill targets.
On-site supervision of the diamond drill program was provided by Aurora Geosciences Ltd. of Whitehorse, Yukon and drill core samples were analyzed by ALS Chemex Labs Ltd. in Vancouver, BC.
