| | Key
The Key project is prospective for both precious metals and volcanogenic massive sulphide (VMS) discoveries. The property straddles an apparent graben developed in a volcano-sedimentary sequence and covers an area with anomalous lake sediment geochemistry and locally anomalous gold-lead-arsenic-silver-zinc in soils. The anomalous metal suite and geological setting is characteristic of the gold- and silver-rich Eskay Creek deposit in northwest British Columbia. The area surrounding the Key project is the focus of significant precious metals exploration and claim staking spurred by exploration results on the Blackwater project (Richfield Ventures Corp.), and the Capoose and 3T's projects (Silver Quest Resources Ltd.). At Blackwater, disseminated gold-silver mineralization and high-grade gold in shear-hosted veins is hosted in Jurassic aged Hazelton Group rhyolites. The 3T's is described as a bonanza-style, epithermal gold-silver camp also hosted by Hazelton Group rhyolites. The Capoose silver-gold-lead-zinc deposit, located 27 kilometres to the northwest, is associated with younger Cretaceous-aged rhyolitic sills that have intruded the Hazelton rocks. Current and historical resources are reported for the three properties. VTEM Survey A 165 line-kilometre helicopter-borne VTEM survey by GEOTECH Ltd. was completed over the central portion of the Key property in August 2008. The survey clearly delineated major north-trending fault systems that cut the property and may be related to the gold and silver mineralization currently being explored by Richfield on the Blackwater property. Four priority EM targets were identified that are considered potential structurally-controlled sulphide-alteration zones. The survey also identified a number of intrusions which may have associated gold-silver mineralization. The Key project contains rocks of similar age and type to those hosting gold mineralization on the Blackwater property, and have never been explored for gold-silver mineralization.
2010 Exploration Program Exploration crews mobilized to the Key property in mid-May 2010 to commence reconnaissance prospecting and sampling of several target areas. Outcrop exposure on the property is limited; however,five areas with coincident gold-silver-zinc mineralization and locally tungsten have been identified. Maps showing the distribution of gold, silver, zinc and tungsten in prospecting samples are presented below.
The anomalous values are typically associated with pyrite and sphalerite +/- arsenopyrite mineralization in sericite, silica, chlorite and locally garnet altered host rocks. Historic showings on the property have been located and appear to be structurally controlled. A preliminary investigation of a broad geochemical trend of anomalous zinc, copper, lead, arsenic and silver values through the central part of the property also points toward a relation to major northerly-trending structures. Magnetite veins, garnet and potassic feldspar and epidote alteration occur in the area of a buried intrusive, interpreted from geophysics, in the southeast corner of the VTEM survey area. The alteration may be indicative of alkali porphyry-style gold-copper mineralization.
Outcrop exposure on the property is limited. Troymet initiated a program of line cutting, induced polarization (IP) and soil sampling over selective grid areas in October 2010. The program was suspended in mid-November with onset of winter conditions, to be recommenced as soon as conditions permitted. Results from the soil sampling and initial IP coverage in conjunction with earlier prospecting results have identified coincident gold-silver in rock samples, gold in soils, and chargeability/resistivity anomalies. The soil analyses also indicate elevated to anomalous gold and silver values over the eastern (Scarp and Butte) grids. The elevated to anomalous values coincide well with the gold and silver in rock samples, and structures believed to control the mineralization. Digitalization and integration of historical soil sampling data with the 2010 data has also been completed; the results of which further augment the delineation of multiple anomalous target areas. 2011 Exploration Program
Approximately 12.6 kilometres of induced polarization ("IP") survey were also completed in the area of Good News Lake. The IP survey identified a large anomaly over 1.2 kilometres in length that is coincident with the gold-in-soil anomalies along the GN Fault. IP anomalies were also identified along the East Fault. Highly anomalous porphyry style mineralization was intersected in five widely-spaced holes in the area of Good News Lake. Individual holes carry copper or molybdenum +/- zinc, and locally weak to moderate silver and elevated to anomalous gold. The mineralization occurs in altered volcanics capping a multi-phase intrusive that is postulated to extend over a 4- to 5-km areal extent. The magnetic signature includes a 1-km diameter magnetic low that appears to be the focus of the porphyry mineralization. Further drilling is required to determine if a viable copper-molybdenum deposit is present. Further details are provided in the Company's May 9, 2011 News Release. The first phase of the 2011 soil sampling program conducted in May-June targeted the eastern side of the property, along the East Fault, and within and along a prominent aeromagnetic feature which appears to extend as far as the adjacent Blackwater gold deposit. The second phase of soil sampling completed in September-October expanded areas covered in the first phase and covered principal target areas adjacent to the Blackwater property. As part of the Phase II program, access routes were identified to a number of drill targets in the area of Tsacha Mt. which were inaccessible during the winter 2011 drill program due to terrain and weather. These, and newly identified targets, will be tested when drilling resumes. Soil sampling in the southwest corner of the Key property has been postponed to 2012 following planned logging of the area. This will result in a more comprehensive and cost effective exploration program in an otherwise difficult to access area. The southwest corner is adjacent to the 3Ts gold-silver deposit where Silver Quest has reported an NI 43-101 compliant resource estimate of 942,600 tonnes grading 4.89 g/t gold and 77 g/t silver. Troymet believes the Key project has significant discovery potential. Exploration on the Key project is at a very early stage - to date less than a third of the property has been explored in any detail and expenditures are small in comparison to other flanking projects where significant discoveries have been made.
