Apr 07, 2016 (A Wilson) - The Timiskaming sediments here form a northwest-trending lens that is approximately 4 km long and several hundred metres wide, spatially associated on its southwest side with an alkaline intrusion of probable syenitic composition. Texture, composition and the spatial association of the intrusion with Timiskaming sedimentary rocks suggest that the intrusion may be part of the regional syn-Timiskaming magmatic suite. This magmatic suite is spatially associated with fault related basins, associated Timiskaming clastic sedimentary rocks, and locally coeval alkaline volcanic rocks which are interbedded with the Timiskaming sediments in basins along, and spatially associated with, the Destor-Porcupine and Cadillac-Larder Lake fault systems throughout the region. Mineralized zones occur along and adjacent to the eastern end of the Timiskaming lens, which in the area of the mineralized zones trends northerly and dips steeply to the east. Drilling suggests that east of the mafic-sedimentary contact, the stratigraphy in the mafic volcanic sequence also trends north and dips steeply east. The sequence comprises alternating massive, pillowed and variolitic mafic units, and local thin volcanosedimentary horizons. Drill core observations suggest that the sequence is generally weakly foliated, despite proximity to the intense ductile strands of the Destor-Porcupine Fault system to the north, although some lithologies including sedimentary horizons and contacts may have localized displacement, as suggested by cataclastic breccias and narrow semi-brittle shear zones associated with mineralization.

Apr 07, 2016 (A Wilson) - The mineralization observed on the Grey Fox property occurs in association with quartz-carbonate veins which are often sheeted and occur at shallow to moderate core axis angles in drill holes which are drilled with from east to west with westerly azimuths, which is the dominant drilling direction. The veins in examined drill intersections form closely spaced sets 0.2 to 10 cm thick. Veins often have a complex, polygenerational history. In the 147 Zone, veins often have thin margins of crustiform banded quartz, overgrown by crustiform a quartz matrix breccia over, and later development of cores of fine-grained, matrix-supported quartz-carbonate matrix lithified vein breccia containing fragments of earlier quartz phases. These veins also often have thin, dark green-grey breccia selvages with abundant disseminated pyrite; petrography indicates they are carbon-bearing. Visible gold was most commonly observed in these dark pyritic rims. Outer reddish selvages beyond the greenish-grey pyritic rims are locally present, and also occur surrounding some veinlets, suggesting redox changes during vein evolution which likely contributed to gold deposition. In other areas, veins form brittle networks that may anastomose but are generally subparallel and sheeted, with earlier vein generations containing grey quartz and later crosscutting carbonate dominant phases.
