Property Location Map
The 8,178-hectare Golden Eagle project is located in northwestern British Columbia, just south of the BC-Yukon border. The South Klondike Highway runs through the centre of the property, providing excellent access from Whitehorse, Yukon, 90 kilometres to the north. Troymet controls a 100% interest in the property through a mix of 100% owned claims and optioned claims.

Tintina Gold Belt

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

Geology & Target Zones
Exploration on the property from 2005 to 2008 focused on the Middle Ridge/Tannis area, where high-grade gold-silver mineralization is hosted in pyrite and arsenopyrite bearing quartz veins/structures within rhyolitic intrusive, granitic intrusive and to a lesser extent in flanking metavolcanics. The first drill testing of the zone was undertaken in 2005, when three holes (TAN05-01 to 03) targeted the depth extension of two mineralized structures exposed in trenches on the north flank of Middle Ridge. The program was highly successful, tracing mineralization over a 100-metre strike length and to 50 metres depth. Follow-up diamond drilling in 2006 allowed for the completion of one hole (TAN06-04) before winter conditions prevented further drilling in the area. This hole targeted 50 metres down dip of the intersection in TAN05-01 and intersected quartz-arsenopyrite-pyrite mineralization over 6 metres core length (Table 1).

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

North Prospect Location Map
Results of the 2008 program indicate the presence of large intrusion-related gold system spanning the ~12-kilometre strike length of the northern half of the Golden Eagle property. At Tannis, the mineralization is hosted in rhyolitic intrusive, in granitic intrusive at depth beneath the rhyolite, and to a lesser extent in the flanking mafic volcanics. Further to the north, the rhyolitic and granitic intrusives are capped by sediments and mafic volcanics of variable thickness. Multiple zones of gold-silver-arsenic-antimony mineralization (e.g. Plateau, Skarn, West Gully, Cowboy, and West Draw zones) and gold-in-soil anomalies occur in this ~5 x 5 kilometre area, known as the North prospect. These zones have previously been investigated in isolation and not considered as underlying vectors toward a related bulk-tonnage gold deposit(s).

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.

North Prospect - Apparent Resistivity


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.

Model of Potential Gold Traps
The style and areal extent of mineralization at Golden Eagle strongly suggest a reduced intrusion-related gold system (RIRGS). RIRGS are characterized by widespread arrays of sheeted auriferous quartz veins, forming bulk-tonnage, low-grade gold deposits at the top of small plutons. Well known examples include the Fort Knox (Alaska) and Dublin Gulch (Yukon) deposits of the Tintina Gold Belt. RIRGS also include a wide range of intrusion-related mineral deposit styles including skarns, replacements and distal veins that form within the region of hydrothermal influence surrounding the causative pluton. All of these characteristics are well represented over the 25-kilometre span of the Golden Eagle property.

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 Table 1 below.

The Company is pleased with the results, which 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.

Troymet believes the North prospect may host one or more bulk-tonnage gold deposits. As a result of data compilation and exploration that commenced in 2009, Troymet has identified three primary targets for future diamond drilling:

In addition, numerous new stream sediment gold anomalies remain to be followed up (see News Release of December 21, 2009).

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.

The west Gully target comprises a granitic intrusive with structurally hosted gold mineralization. Several chargeability targets were identified including anomalies that occur along strike of 2009 drill hole N0901 (0.11 g/t gold over 86.84 metres including 0.33 g/t over 15.24 metres; February 17, 2010 News Release.

Three drill holes tested chargeability targets over a distance of approximately 500 metres along strike of hole N0901. The chargeability targets are partly aligned along a drainage with anomalous gold-in-silt values. A fourth hole drilled at 180 degrees to N0901 was lost in a cave associated with old workings, with the result that the depth extension of the mineralization in N0901 was not tested. The fifth hole tested a chargeability target along the northeast faulted contact of the intrusive. Drainages rising in this area contain anomalous gold-in-silt values. The sixth hole was drilled in the Skarn zone before weather conditions forced the termination of the program.

A more extensive helicopter supported drill program had been planned for 2011 but due to adverse weather conditions this program has now been deferred to 2012.

Drill core samples are being analyzed by ALS Chemex Labs Ltd.; results will be reported once received, interpreted and validated.
