Dec 07, 2005 (G Seim) - The Pominex Deposit is contained within a felsic feldspar porphyry dike along the contact of mafic metavolcanic rock to the south and ultramafic rocks to the north. The dike is about 60 m wide, strikes 080/70S The dike has sharp contacts and contains inclusions of pillow lava. The dike is sub parallel to the Gold Island - Aquarius fault located about 100 m to the north.

Jun 25, 2013 (G Seim) - The felsic feldspar porphyry is light-grey to green, very hard and consists of an aphanitic groundmass with scattered feldspar phenocrysts. Hydrothermal alteration locally bleaches out the phenocrysts.

Jun 25, 2013 (G Seim) - A gold-bearing felsic feldspar porphyry about 60 m wide strikes 080º and has been traced for about 2 km. Significant gold values were intersected in drilling over a length of 1600 m length of the dike centred south of Homestead Lake. The central main zone of gold mineralization ranges between 8 and 15 m in width with parallel subsidiary zones. Better gold concentrations were intersected below the 175 m level. Typically, the core of the main gold zone is silicified, white in colour, fractured and contains about 10 percent quartz stringers and 1 percent partially oxidized pyrite. The mian zone is haloed by partially silicified, less fractured, grey-green porphyry containing only traces of disseminated pyrite.
Jun 25, 2013 (A Wilson) - Typical assays ranged from 0.002 oz/t Au over 5 feet to 0.008 oz/t Au over 5 feet. Anomalous values of 1.8 oz/t Au over 1.2 ft were obtained from DAQ80-2. Assays from the 2003 diamond drilling program completed by Kinross returned values ranging from 1.05 g/t Au over 1 m to 6.62 g/t Au over 1 m in P-03-15.

Geologist: G Seim
Notes: Some drill core from the Pominex Ltd. drilling is stored at the Timmins outdoor core storage facility. The Pominex Deposit does not outcrop. Diamond drill core from hole 84-17 was examined on July 31/02. This hole was drilled from the hanging wall mafic metavolcanic rocks through the felsic feldspar porphyry and then into the footwall ultramafic rocks. Toward the contact with the porphyry, the mafic metavolcanic rocks becomes silicified and less calcitic. Pillow selvedges are noted to contain clots of pyrite, epidote, carbonate and minor purple quartz. Silicification increases toward the contact and is evidenced by - candy striping - of the drill core. The entire intersection of feldspar porphyry was split and assayed, but the assays were never filed with the drill logs. The description of porphyry as noted in the drill log is accurate, but visible gold noted in 2 sections could not be relocated. The top of the porphyry is grey-green in colour, moderately silicified, fractured and contains 1 percent fine, disseminated, euhedral pyrite. The - main zone - of gold mineralization is grey to white in colour, intensely silicified, intensely fractured, but does not contain an appreciably greater concentration of disseminated pyrite. Locally quartz veining comprises more than 50 percent or the rock over a 1.5 m interval. Below the - main zone - the porphyry becomes increasingly less altered and fractured and contains only traces of pyrite.
