The Key project is prospective for both precious metals and volcanogenic massive sulphide (VMS) discoveries. The property straddles an apparent graben developed in the Jurassic-aged Hazelton Group 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.
Outcrop exposure on the Key property is sparse and limited to the peaks and ridges. As a consequence, soil geochemistry and geophysics are important exploration tools. 2008-2011 Exploration Programs 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 on the adjacent 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, and three possible diatremes/breccia pipes. The possible diatremes are overburden covered and are located within an area of low magnetic signature measuring approximately 130 hectares. Diatremes/breccia pipes are a common host for gold-silver mineralization, and have been mentioned in connection with the Blackwater gold deposit. These may be an important target on the Key project. In 2010, the Company conducted reconnaissance prospecting and sampling over the central project area, followed by induced polarization ("IP") geophysical surveys and soil sampling on selected grid areas. Five areas with coincident gold-silver-zinc mineralization and locally tungsten were identified. The anomalous values are typically associated with pyrite and sphalerite +/- arsenopyrite mineralization in sericite, silica, chlorite and locally garnet altered host rocks.
Drilling in the Good News Lake area intersected highly anomalous porphyry-style mineralization with 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 kilometre areal extent. The magnetic signature includes a one kilometre diameter magnetic low that appears to be the focus of the porphyry-style mineralization. An IP survey completed in the Good News Lake area in 2011 identified a large chargeability anomaly over 1.2 kilometres in length that is coincident with gold-in-soil anomalies along the GN Fault. The anomaly suggests the presence of a large hydrothermal system with high sulphide content. IP anomalies were also identified along the East Fault. 2012 Exploration Program
The 2012 field program included detailed infill soil sampling of previously identified gold-in-soil anomalies, prospecting, line cutting, IP surveys and drill testing of select targets within the 12 principal anomalous zones. Active logging severely restricted access for drilling with the result that only four target areas were drilled: Buzz, SGN, Blue and P1A. Access to the SGN anomaly was restricted to the northern end of the anomaly at Good News Lake -- the core of the anomaly has not been drilled. Access to the Blue anomaly was restricted to two sites. Hole RC-10 intersected bedrock gold mineralization in the Buzz B anomaly; holes RC-15 and RC-16 intersected wide zones of alteration carrying anomalous gold +/- silver at the north end of the SGN anomaly; and hole RC-01 intersected anomalous copper over a significant width in the Blue anomaly. The area continues to be actively logged and it is anticipated that there will be excellent access for drilling of all target areas and for surface exploration upon completion of the logging program. See January 14, 2013 news release for complete details of the 2012 drilling.
