Location Method: Data Compilation
1945: McBuck Red Lake Mining Limited completed mapping, drilling and trenching focused on finding extensions of the McFinley Mine mineralization. 1946: Marshall Red Lake Gold Mines completed a mag survey and drilled three holes. 1952: Bright Red Lake Gold Mines drilled 3 holes, without releasing the results. 1981: Placer Dome Canada Ltd. staked 16 claims based on results from a government airborne geophysical survey. They followed up with ground geophysics and diamond drilling which led to staking 37 additional claims. Little work was recorded on the ground until a 1986 diamond drill program which returned 3.1 g/t Au over 0.5 m. During the early 1990s Placer completed ground magnetic, IP and EM surveys and additional diamond drilling. In 1992, a drill hole intersected 15.15 g/t Au over 0.61 m associated with a interesting geology and alteration package. Follow-up drilling returned anomalous results in 5 of the 6 drill holes. This work and subsequent work targeted Campbell Mine style mineralization at the contact of the mafic volcanic rocks and the East Bay serpentinite, particularly in the East Bay Deformation (Shear) Zone. In 2003, Placer Dome and Wolfden entered into a 50:50 joint venture agreement for further exploration and development of the property. An inferred resource estimate was released by Placer Dome in 2005 comprising 1,399,105 tonnes, with an average grade of 8.00 g/t, for a total resource of 326,407 contained ounces of Au. Subsequent diamond drilling in 2003-2005 on 25 m centres was used to calculate a new resource estimate which has yet to be made public (Feb 2007). To the end of 2005, 165 diamond drill holes have been drilled on the East Bay property, for a total of 59,546 m.

Feb 11, 2014 (Syed Ali) - Assay: 2013 DDH program •115.46 g/t Au across 0.6 m (3.37 oz/ton across 2.0 ft) in FW2 Zone in hole EBJV13202. This hole is drilled down-dip of previously drilled holes EBJV12196 that intersected 58.36 g/t Au across 1.0 m (1.70 oz/ton across 3.3 ft) and EBJV12198 that intersected 69.23 g/t Au across 0.9 m (2.02 oz/ton across 3.0 ft). - 10.26 g/t Au across 3.0 m (0.30 oz/ton across 9.8 ft) in a new area approximately 1 km north of the main Footwall Zone.
