Jun 26, 2013 (G Seim) - Echo Bay DDh 96-303 was drilled on an azimuth of 344 degreeswith an inclination of -60 degrees. The hole collared through 27.7 m of overburden in a talc-chlorite schist. From 77 m to 80 m the rock graded from talc-chlorite schist to a stongly fuchsitic carbonate rock. This unit contained many quartz-carbonated veins and less than 1% disseminated pyrite. It yeilded anomalous to occurrence-grade gold values upon assay. The carbonate rock continued to a depth of 121 m after which the rock graded back to talc-chlorite schist. The interval from 122 m to 147 m was talc-clhorite schist, however, portions were carbonate/albite altered. This unit also returned anomalous to occurrence-grade gold values upon assay. The interval from 147 m to 156.2 m is described as mixed carbonate rock with chlorite and talc. This interval yielded the highest gold value in the hole, 4938 ppb au over 1.0 m. From 156.2 m to the end of the hole at 201.00 m, the hole cut talc-chlorite schist exhibiting some remnant spinifex texture.

Jun 26, 2013 (G Seim) - A 1 m section of fuchsitic carbonate rock between 81 and 82 m assayed 990 ppb Au. A 1 m section of mixed mafic metavolcanics assayed 4938 ppb Au between 147 and 148 m.
Jun 26, 2013 (G Seim) - The carbonate rock is described as iron carbonate with minor grey brown carbonate, fine- to medium-grained, bright to pale green patchy carbonate alt., massive anastomosing carbonate veins and quartz carbonate veins, good sound rock, non magnetic.
