The Jennings occurrence is located 80 kilometres west of Watson Lake, Yukon about 700 metres south of the British Columbia-Yukon border. In the past, the property has been accessible by 32 kilometres of two and four-wheel drive road south and east from Rancheria on the Alaska Highway. The access route utilizes the Midway-Silvertip road south from the Alaska Highway with bridges in place at the Rancheria and Tootsee River crossings. The main river crossings along with other stream crossings were washed out during flooding in the summer of 2012; therefore, there was no vehicle access during a 2012 exploration program.
Observations from previous work have determined the Jennings property is underlain predominantly by calcareous and pelitic sediments and minor limestone of the Cambrian-Ordovician Kechika Group. Kechika Group sediments are flanked to the southwest by variably calcareous quartzite, shale and graphitic argillite with minor limestone of the Silurian-Lower Devonian Ramhorn Group. Although minor folding is observed, rocks generally strike north to northwesterly and dip moderately to steeply west. A broad area of thermally metamorphosed light green calc-silicate and pelitic hornfels +/- disseminated pyrrhotite (trace-5 per cent) that is often banded with biotite hornfels, marble or dark green pyroxene skarn and cut by variably sericite altered aplite and quartz-feldspar porphyritic dikes, has been mapped and cored in the central and northwestern Jennings property area (Central Jennings zone located in Yukon). Drilling completed in 2006 on the Central Jennings zone intersected moderate to strong stockwork quartz-scheelite-molybdenite fractures and veining in variably hydrothermally altered sulphidized calc-silicate hornfels, pyroxene skarn and quartz-feldspar porphyry below 150 vertical metres.
The principal exploration target on the Jennings property on the British Columbia side is a porphyry-style tungsten-molybdenum deposit with potential for peripheral carbonate-hosted silver-lead-zinc skarns or veins. Historic diamond drilling reportedly intersected fracture and vein controlled scheelite, wolframite and molybdenite mineralization on the Yukon side of the border.
The 2012 Jennings exploration program in British Columbia consisted of three diamond-drill holes for a total of 1496 metres. Drillholes were designed to test multi-element (arsenic-molybdenum-lead) soil anomalies identified from work in 2009 and 2011. All drillholes in the 2012 exploration program intersected quartzite from surface followed by variably hydrothermally altered and fractured biotite and calc-silicate hornfels. Significant fracture and vein hosted molybdenum and tungsten mineralization encountered in historic drilling on the central and northwestern claims in the Yukon, was not identified in 2012 drilling. In British Columbia, a single molybdenum mineralized sample was returned in drillhole JSP12-001 grading 1030 parts per million (parts per million) molybdenum over 2 metres from 115 to 117 metres downhole depth (Assessment Report 33558). The sample was enveloped by 191 parts per million molybdenum over 14 metres from 107 to 121 metres and only weakly elevated tungsten. The drill core associated with this result is interbanded, dark, fine grained calcareous mudstone and pale calc-silicate hornfels, with no conspicuous variation from surrounding core.
Despite low assay values, it is encouraging that the geological units with minor chlorite-pyrrhotite-calcite fracturing encountered in the 2012 drilling are found to be spatially associated with mineralization at the Central Jennings zone. Molybdenum and associated elements were elevated in the upper 150 metres of the drillholes which may account for part of the surface soil anomalies.
In 1978, Amax of Canada Limited identified elevated concentrations of scheelite in drainages east of the property in the course of regional exploration. Anomalous scheelite was traced west to a package of steeply dipping calc-silicate hornfels in the current Jennings project area. Claims were staked in 1979 followed by line cutting, geological mapping, panning, stream and soil geochemical surveys, UV lamp prospecting, VLF-EM and magnetic surveys through 1980. Diamond drilling in late 1983 consisted of two holes in the Yukon and one hole in British Columbia for a total of 787 metres. A 1985 program consisted of 1:2000-scale geological mapping, soil and rock geochemistry, a 162 line-kilometre airborne magnetic-EM survey and construction of 11.3 kilometres of access road, drill road and drill sites.
Cumberland Resources Ltd. staked the peripheral Tooz (Yukon) and Tootz (British Columbia) claims in May-June 2005 and optioned the core Hot claims from North American Tungsten Corp. in April 2006 and completed three diamond-drill holes on the Yukon side of the property intersecting molybdenum-tungsten (Central Jennings zone) fracture controlled mineralization. In 2007, Cumberland Resources Ltd. was taken over by Agnico-Eagle Mines Ltd. and the project was renamed as the Jennings Project. Agnico-Eagle conducted soil geochemical sampling and diamond drilling programs in both the Yukon Territory and British Columbia in 2009 and 2011. In 2012, Agnico-Eagle conducted an exploration program in British Columbia consisting of three diamond-drill holes for a total of 1496 metres.
