The Shae occurrence is located on the south side of Little Cedar River about 45 kilometres northwest of Terrace.

The Shae showing was discovered 1.5 kilometres east of the Macex (103I 021) occurrence on the LCR property in 2004. A partly unroofed body of Cretaceous quartz monzonite underlies the claims in the Shae zone and is emplaced within sedimentary rocks of the Middle Jurassic to Late Cretaceous Bowser Lake Group.

At the Shae occurrence, sulphides are developed in fractured hornfels greywacke and at the contact with quartz biotite porphyry and in the intrusive rock. Mineralization consists of disseminated pyrite, pyrrhotite and chalcopyrite and is concentrated in a 20-centimetre thick hydrothermal breccia zone. Massive replacement-style mineralization, like that in angular float, is also noted in the host rocks and is attributed to emplacement of the mineralized intrusion.

The Kai (KA!) zone is located approximately 400 meters to the south west at an elevation of approximately 600 metres and comprises a 1.5 metres wide fault zone hosted by a graphitic rich lithic arenite containing semi-massive pyrite and pyrrhotite with minor chalcopyrite associated with quartz stockworking. The fault zone strikes 298 degrees and dips north easterly at 65 degrees.

See Macex (1031 021) for further details of the property.

In 2004, an extensive exploration program was conducted by Eagle Plains Resources Ltd. and included a 545.9 line-kilometre VTEM geophysical survey conducted in March, plus a later geochemical survey totalling 707 soil samples, 110 silt samples and 110 rock samples. A 3-hole diamond drill program (483 metres) was drilled as well. Geologic mapping identified the potential for a high-level epithermal system overlying the copper-molybdenum porphyry system. It also resulted in the discovery of the Shae copper-molybdenum porphyry/copper-replacement showing (103I 229). The airborne geophysical survey delineated intrusive bodies whose contacts often are associated with mineralization. The soil geochemical sampling program was the most useful tool in the project. The Elsiar soil geochemical sample grid outlined a prominent copper-molybdenum anomaly over an 800 by 800 metres area which is open to the north and east. The three exploration holes successfully tested the subsurface extent of the mineralized quartz-carbonate stockwork at the LCR showing.

The 2005 Eagle Plains Resources exploration program consisted of three main components: reconnaissance geochemical and prospecting work to the south and east of the main focus area; detailed geologic mapping and infill geochemistry within the main focus area; and diamond drilling (20 holes totalling 2556 metres) of major targets defined during the 2004 and 2005 field work seasons. Sampling of a 10-metre long trench on the Shae occurrence yielded values up to 0.57 per cent copper, while grab samples from the Kai zone yielded from 0.5 to 2.08 per cent copper (Sharp, R.J. (2008-01-22): 2008 Exploration And Geological Report for the Elsiar Cu-Mo Porphyry Property). Three diamond drill holes (LC05001 to LC05003) were also completed on the Shae occurrence yielded intercepts of up to 0.100 per cent copper and 1.0 gram per tonne gold over 1.0 metre in hole LC05003 (Sharp, R.J. (2008-01-22): 2008 Exploration And Geological Report for the Elsiar Cu-Mo Porphyry Property).

The 2008 exploration by Eagle Plains Resources on the Elsiar property was carried out in two phases. The first phase of exploration was a geochemical survey (soil and silt sampling) between June 30 and July 21, and the second phase, from September 8 to September 14, consisted of geological mapping, and additional geochemical sampling of soils and stream sediments. Field work consisted of detailed geological mapping, following up known geochemical anomalies, stream sediment and contour soil geochemical sampling. TerraLogic Exploration Inc. conducted the program on behalf of Sandstorm Resources.

The 2010 exploration by Eagle Plains Resources was to follow up geochemical anomalies in float rock, stream-silt and soil samples determined during previous 2005-2008 field programs. Areas proximal to these anomalies and new areas of interest with insufficient previous sampling were prospected and/or geologically mapped, with some additional silt, soil or rock sampling.

In 2011, on behalf of Eagle Plains Resources Ltd., a ground-based induced polarization and magnetic geophysical survey over 9.1 line-kilometres was completed in the central zone of the Elsiar property.
