Jan 23, 2014 (A Wilson) - Diamond drilling intersected a sequence of pillowed to massive andesite/basalt. Both drill holes intersected sequences of tuffaceous andesite as well as sequences of leucoxene alteration. DDH-035 intersected 128.7 m of porphyry between 82.1 and 210.83 m. The porphyry is described as fresh with some light pervasive calcite alteration. The porphyry is described as containing 25-40% feldspar phenocrysts ranging in size from 3 to 8 mm in size. Subhedral feldspar phenocrysts up to 10cm in size also were observed within the unit.

Feb 27, 2008 (D Draper) - Hole 28 (az. 146, dip -47): A unit of tuffaceous andesite @ 230m downhole with quartz stringers and veinlets and mineralized with py and sp, assayed 1726 ppb Au over 1.08m and 580 ppb Au over the next 0.5m. Wire silver was also noted within the first sample location but no significant Ag results were returned. (T-3787) Hole 35 (az. 151, dip -64) was collared approx. 60m east of 28. While no elevated Au values were returned, an assay of 9761 ppm Zn and 3369 ppm Pb over 0.3m was obtained from a unit of graphitic andesite at 70m downhole. (DCL TI 4367)
