The Sawmill Creek Project is part of the Caledonia Highlands of southeastern New Brunswick that forms the Avalon Terrane of the transcontinental Appalachian orogenic system. The lithology, age, geochemistry, alteration, and geochronology of the Caledonia Highlands are strikingly similar to the geology of the mineralized Carolina Slate Belt and Burin Peninsula of Newfoundland. The Avalon Zone contains Late Neoproterozoic to Cambrian (570–545 Ma) bimodal volcanic rocks, (rhyolite and basalt), associated with co-magmatic intrusions (granite, diorite, and gabbro). Most lithologies are either metaigneous or metasedimentary. This is another historical, overlooked gold discovery located west of Moncton, New Brunswick, being investigated by Geosearcher Inc. It is part of the Fundy Shear Zone, a regional, deep-rooted, sparsely-explored Appalachian fault system that is becoming New Brunswick's newest emerging Gold District. The Funday Shear Zone stretches along the coast of New Brunswick from St. Stephen, N.B. to Moncton, N.B.
New discoveries along this trend by Robert Murray of Geosearcher Inc. include significant gold, silver, and copper mineralization. Particularly 67 g/t Au at Little Lepreau and 70 g/t Menzies Lake that enhance the gold mineral potential along this trend of the Caledonia Highlands. These new discoveries, coupled with historical ones, provide insight into a well-established, past producing copper-gold-silver district. Prospective mineral deposit systems include primary porphyry, primary IOCG systems, secondary IOCG overprints, and orogenic lode gold (+ copper + silver) systems. The Sawmill Creek Project is a highly perspective lode gold system.
The limited historical record for Sawmill Creek shows that there have been minor, yet noteworthy, discoveries. Selwyn (1892) reported abundant pyrite and minor gold in a "felsite schist"; however, the location along Sawmill Creek is not known. In 1933, Flaherty reported specularite in quartz stringers cutting an aplite dyke somewhere along the same creek. Then again in 1947, Bichan reported minor gold in a pyritic zone contained in a rhyolite tuff, near its contact with a pillowed lava. Again, the exact locations of these previous discoveries remain a mystery yet indicate that gold was hosted by the felsic volcanic rocks of the Neoproterozoic Broad River Group outcropping along Sawmill Creek.
Geosearcher Inc. has selected this claim area as the most likely source of the gold mineralization due to the presence of a significant magnetic high (yellow lines) and a gravity high (red lines) along a geological contact of a known rhyolitic and mafic unit that has abundant pyrite (Map 3). Given that this location has these noteworthy similarities not only to the historical record but to other known mineral deposits along this trend, this contact is a primary exploration target.
