The Bug Lake Gold Trend (“BLT”) is a north-northwest trend of gold mineralization located within the south-central part of the Martiniere Property. The BLT marks the location of a significant fault structure which sits between the east-west trending, regional scale Sunday Lake deformation zone and the recently identified Lac du Doigt deformation zone which parallels the Sunday Lake approximately two kilometres to the north.
The BLT is located along the site of an early and frequently re-activated north-south striking, steeply to moderately east-dipping fault zone (the Bug Lake Fault). This fault zone separates a gabbro dominated domain to the west (host to the Company’s Martiniere West gold deposit) from a mafic volcanic dominated domain to the east.
The Bug Lake fault system is cored by a fine-grained, quartz porphyry unit. This porphyry, is flanked by zones of strong brecciation and local shearing, moderate to intense silica flooding and sericite alteration. Gold mineralization, typically in association with fine-grained pyrite, occurs throughout the silica flooded alteration zones surrounding the porphyry and in sub-parallel structures and vein zones developed in the hanging wall and footwall to the Bug Lake Fault system.
High-grade gold mineralization (> 3 g/t gold) is associated within zones of increased pyrite mineralization, quartz veining and minor gold mineralization within the most intensely altered and deformed portions of the Trend. Broad lower grade halos typically surrounding the higher grade gold mineralization over metres to tens of metres.
To date drilling has traced the gold mineralized system along the BLT for over 1,800 metres and to vertical depths of over 700 metres and the system remains open to depth. Gold mineralization occurs in several discrete zones which collectively span widths of 30 to over 120 metres centered around the Bug Lake fault system.
One of the unique aspects of the Bug deposit is the high angle at which the mineralized structure cuts through the local stratigraphy. The two meet at 75-85 degree angles. The steep dip of the Bug Lake fault and moderate (approx.. 60 degree south) local dip of the stratigraphy combine to set up southeasterly plunge lines for each of the main zones within the Bug deposit. In addition gold mineralization shows a tendency to “bleed out” along zones of competency contrast within the stratigraphy.
An initial resource estimate for the Bug Deposit, derived from its four principal zones and near surface satellite deposits, outlined potential for a near surface open pit some 1,000 metres long followed by potential underground develop with grades consistent with producing deposit located throughout the Abitibi region.
