The Fox property is located approximately 70 kilometres northeast of 100 Mile House in the south Cariboo region of British Columbia, Canada. With seven mineralized zones in a 10 km by 3 km mineral system and high tungsten grades in outcrops and drill core, the Fox property is thought to represent an important new tungsten prospect in the western world. The Company has taken the project from a very early stage to where resource expansion drilling and engineering studies are being conducted.

January 26 2017 NI43-101 Resource update
The mineral system is overall 10 km by 3 km in dimension, centred around a granite intrusive. The Nightcrawler-Discovery and South Grid areas occur on the south side of the granite, and on Deception mountain, from south to north respectively, five outcropping zones (708, BN, RC, BK and North zones) occur over a three kilometre distance. These zones all have positive tungsten values in outcrop and/or drill core, and all zones are open in extent.
Scheelite (Calcium tungstate) mineral fluorescence is bluish-white under Ultra Violet light.
1997 - 1999: Prospecting of new logging roads identified favorable intrusive and calc-silicate rocks. Molybdenum first identified at Discovery zone followed by positive tungsten in assays.
2000 - 2004: Privately funded prospecting, soils, silts, UV lamping. High grade boulders (moly and tungsten) found at the Discovery zone then to the east at the Nightcrawler zone. Similar geological setting and positive stream sediments located on Deception Mountain 4 km to the north.
2005 - 2010: Happy Creek acquires property and conducts larger scale prospecting, geochemistry and geology. Trenching and wide-spaced drilling at Nightcrawler zone gives positive results in an area 1.5 km X 500 metres in dimension. Trenching on Deception Mountain returns 2 metres of 5.0% W03 (Ridley Creek (RC)), 7.25m of 1.25% W03 (BK), and 1.0m of 4.66% W03 metres (BN) in three zones over 2.0 km.
2011 - 2013: In 2011, drilling at RC zone intersected 5.2metres of 0.91% W03, 4.7m of 1.02% W03, and 12.4m of 0.74% W03, which are considered the “Discovery” point for the project. Under increasingly difficult market conditions, globally top-tier results include 26m of 1.2% W03 at RC and 14.8m of 4.0% W03 at BN. With limited funding available, only the RC zone was selected for additional drilling. A LiDAR topographic survey and additional geology was completed.
2014 - 2015: Airborne geophysics, geological mapping, sampling. Geochemical survey identifies large South Grid target. The North zone was better defined at surface and addition zones of tungsten located. In 2015, drilling at the Nightcrawler Creek zone returns 5m of 1.0% W03 and the favorable geology containing tungsten values extended another 450 metres further east. More detailed deposit modelling, metallurgy studies undertaken.
2016: Drilling and updated resources for Ridley creek zone, and first resource for BN zone. Drilling increases information at BK zone and returns 6.0 m of 0.67% WO3. Trench and chip sampling at Ridley creek and BK zone. A conceptual process flow sheet and metallurgical studies return positive results.
The Fox property is underlain by a tungsten-molybdenum porphyry type system similar in age to the nearby Boss mountain molybdenum mine. However, on the Fox property the porphyry system is thought to have developed in an anticline of metasediment and limestone units that have been converted to hornfels, calc silicate and skarn. With a large scale "porphyry-driven" mineral system and focussed hydrothermal flow into carbonate units, this favorable geological setting is 10 km by 3 km in dimension.
Snowshoe Group rocks are cut by the Deception Stock that occupies a four kilometre by five kilometre sub-circular area exposed in the central part of the property, in proximity to the fold axis of the regional anticline. An U-Pb zircon age of the Deception stock is 106.4+/-0.2 Ma (million years). A similar age (98-105 Ma) is reported for the Boss Mountain stock located approximately 25 kilometres to the west that is associated with the Boss Mountain molybdenum mine, a significant past producer (See the Company's Silverboss Property). The Deception stock varies in composition from fine to medium grained quartz monzonite to muscovite-biotite granite and locally biotite-hornblende granite. Phases include leucocratic granite or alaskite, pegmatite, aplite and quartz. Numerous felsic dykes, vein-dikes and sills cut the metasediment and stock. Individual dykes are less than one to over five metres in thickness, and comprise quartz monzonite to fine grained leucocratic, quartz and k-feldspar rich granitioid phases, alaskite and aplite. Some dykes and phases of the stock contain disseminations of fine grained, pink-red almandine garnet that suggest a per-aluminous composition. Ring and radial dykes or sills occur around the southern flank of the stock, and a swarm of subparallel dykes and sills extend north of the stock for several kilometres, in proximity to the axis of the regional anticline and roof of the intrusive carapace.
Around the Deception stock, the Snowshoe Group metasediment is hornfelsed and contains pyrite-pyrrhotite for over two kilometres beyond the Deception stock. Zones of tungsten-bearing calc-silicate and skarn occur in proximity to the Deception Stock and related dykes or sills. Multiple stacked skarn or calc-silicate beds that are individually from several centimetres to around 30 metres in thickness together form a package approximately 100-150 metres in thickness within the quartz-biotite-muscovite schist. All rocks are cut by quartz veins and lenses, varying in thickness and attitude. Quartz veins are fine to coarse crystalline, milky white, clear to grey and locally vuggy. Quartz occurs as metamorphic "sweats" that are subparallel foliation of schist, and occur as multiple generations of cross cutting veins with variable textures and contents that are locally associated with k-feldspar and quartz-sericite alteration.
The Fox property is underlain primarily by deformed Snowshoe Group metasedimentary rocks, Upper Proterozoic to Lower Paleozoic (Cambrian?) in age, that include fine to medium grained muscovite-biotite schist, micaceous quartzite, feldspathic and calcareous schist, calc-silicate schist and marble. The marble typically occurs as multiple beds, less than 0.5 metres to around 25 metres in thickness and together with other calcareous, calc-silicate units form several units of between 25 and 100 metres or more in thickness. This unit is termed the Favorable Geology, which hosts the tungsten skarn zones of economic interest.
Calc-silicate and skarn consists of pale orange to dark red or brown colored garnet, pale to dark green colored pyroxene, diopside, amphibole and quartz. Scheelite (calcium tungstate) is the tungsten mineral present. The calc silicate, skarn and fracture fillings within metasediment and intrusive rocks also contain pyrrhotite and pyrite. Other sulphides visible are molybdenite and sphalerite. Although molybdenite occurs in spatial proximity with tungsten, the two metals are thought to be part of separate phases of the mineral system. Molybdenite generally occurs peripheral to tungsten skarn, and very minor powellite (calcium molybdate) is observed locally under ultra violet light at the Discovery zone: more on molybdenum further below. Trace elements (parts per billion or parts per million) include molybdenum, copper, zinc, fluorine, bismuth, cadmium, antimony, indium, lead, gold and silver Scheelite occurs as pale white to grey, fine to medium grained (2-4 mm) crystal disseminations, medium grained bands within pyroxene-garnet skarn and calc-silicate, quartz veins and in quartz-rich zones within the calc-silicate, or in quartz veins and veinlets that cut granite, monzogranite, alaskite and dykes and sills. Coarse grained crystals up to 10 mm occur with intense calc-silicate/skarn zones that are thought to reflect in part, a late stage remobilization. Scheelite locally forms up to 15% of the rock volume in select areas.
