Jan 13, 2015 (A Wilson) - Visible gold was observed in dump material from the inclined shaft which followed the dip of the vein. Samples collected from Keora Porcupine Mining Co. drill hole A-2 returned assays ranging from trace to an average of $17.44 over 9 ft between 76 and 88 ft. Assays from DDH A-1 returned assays ranging from trace to $33.40 Au over 24 inches from vein 3. Assays from diamond drilling completed by North Whitney Mines Ltd retuned quartz veins assaying $5.25 Au over 0.4 ft and $27.65 Au over 0.4 ft. Samples from the underground workings returned assays up to $14.00 Au over 2.5 ft at the western end of the crosscut off of the inclined shaft. Assays from the crosscut off or the 100 ft vertical shaft returned values up to $21.70 over 16 inches although most of the assays were in the $0.70 over 16 inches to $3.50 Au over 12 inches.
