Dec 07, 2005 (A Wilson) - The quartz veins of the Sugar Zone occur in strongly foliated amphibolitized basaltic flows injected by abundant felsic sills that are either very fine-grained or contain quartz or feldspar phenocrysts. This weathered suite of sills is intruded and accompanied by narrow, pyritic quartz veins. The Sugar Zone is a zone of strong flattening and subvertical stretching.
May 26, 2020 (Sheree Hinz) - The mineralized Upper, Lower and Footwall Subzones of the Sugar Zone lie within the Sugar Deformation Zone. They occur within a highly strained assemblage consisting of variously altered mafic volcanic flows, intermediate porphyritic intrusions and boudinaged auriferous quartz veins. The three zones range in true thickness from about 1.5 to 10 m and are separated by 20 to 30 m of unmineralized metavolcanics. Each Subzone is made up of one or more porphyritic intrusions, flanked by altered basalt and hosting conformable quartz veins. Alteration within the mafic metavolcanic portions of the subzones consists primarily of silicification that occurs both as pervasive alteration and as quartz veining, diopsidation and biotization. The porphyry units of the zones exhibit biotite and silica alteration, but lack diopside alteration.

Sep 05, 2012 (A Wilson) - Grab samples collected by the OGS returned values of 1.03 and 2.15 oz/t Au. The best values from channel sampling range from 2.45 g/t Au over 0.46 m to 25.75 g/t Au over 1.41 m. The Sugar Zone is a continuous structure with upper and lower horizons approximately 15-25 m apart. The two horizons comprise multiple feldspar porphyry sills. These silicified, banded horizons contain 1-10% pyrrhotite and pyrite with quartz veins usually along the felsic porphyry-basalt contacts. Best assays from 2003 drilling returned 59.57 g/t Au over 0.32 m from Lower Zone in drill hole CH-58 and 24.10 g/t Au over 0.64 m from the Upper Zone in drill hole CH-57. Gold mineralization mostly occurs in quartz veins, stringers and quartz flooded zones predominantly associated with porphyry zones, porphyry contact zones, hydrothermally altered basalts and, rarely, weakly altered or unaltered basalt within the Upper and Lower zones. Fine to coarse grained specks and blebs of visible gold are common in the Sugar Zone quartz veins, usually occurring within marginal, laminated or refractured portions of the veins. The visible gold itself is often observed to be concentrated within thin fractures, indicating some degree of remobilization. Quartz veins and floods also contain varying amounts of pyrrhotite, pyrite, chalcopyrite, galena, sphalerite, molybdenite and arsenopyrite. The presence of galena, sphalerite and/or arsenopyrite is a strong indicator of the presence of visible gold. Pyrite, chalcopyrite and, rarely, molybdenite form a minor component of total sulphides and do notappear to be directly related to the presence of gold mineralization.

Notes: The major linear structure recognized on the Property is the Sugar Deformation Zone (SDZ) that trends northwest-southeast for approximately 3.5 km and dips southwest between 65° and 75°. The SDZ appears to be spatially related to the Strickland Pluton and is a complex system with strain intensities varying from strongly deformed-pillow mafic volcanics to undeformed massive mafic flows to anastomising linear areas. Stratigraphically-conformable porphyritic intermediate intrusions swarm through the SDZ. Both the mafic volcanics and the intermediate intrusives exhibit moderate linear fabrics along with hydrothermal alteration (i.e., silicification).
