Dec 07, 2005 (A Wilson) - The mineralization is primarily hosted in a set of thin slightly chlorite altered pink granitic bodies. These are interbanded with chloritic, schistose mafic metavolcanics. The schistosity in the chloritic mafic metavolcanics is discordant to the lithological banding. The schistosity trends 170.

May 06, 2009 (D Draper) - In addition to significant gold values, two of the samples collected by Troup and Otten also returned assays of 374 ppm and 571 ppm cobalt. Union Gold sample 348562 returned 789 ppb Au and 431 ppm Co from a 1 m chip sample across a porphyry-volcanic contact (T-5271)
Dec 07, 2005 (A Wilson) - Grab samples collected by Hammerstrom and Koski in 1946 returned values of 4.1 g/t Au. Sampling conducted by Troup and Otton in 1990 returned values up to 2.9 g/t Au. A number of low grade gold values (0.8 - 1.7 g/t Au) were obtained from the sampling conducted by Lorac in 1992. Mineralization is associated with disseminated pyrite which forms the greatest concentrations in the granitic rocks.
