Mar 11, 2014 (A Wilson) - Elevated gold values were returned from metasedimentary rocks with quartz-calcite veining. Mineralized structures were located at porphyry/volcanic contacts, along flow top contacts and interflow sedimentary units, within thin massive tholeiitic units and volcanic breccia units (mainly of the Central Formation of the Tisdale Assemblage).

Mar 11, 2014 (A Wilson) - Gold mineralization at Hollinger was associated with pyrite at the margins of quartz veins, in a wide zone of sericite-ankerite/ferroan dolomite alteration around the western edges of the Pearl Lake Porphyry. Assays from the 2010 technical drilling project returned assays ranging from 0.0025 g/t Au over 1 m to 15 g/t Au over 1 m in quartz ankeritic veins.
