The Annidale Belt in south-central New Brunswick is located near the Gander-Avalon collisional boundary and is host to several occurrences that exhibit features typical of orogenic lode gold deposits. The Devil Pike Brook gold deposit contains the highest gold grades in a set of north-trending en echelon quartz veins hosted by mafic volcanic rocks. These en echelon veins contain visible gold, chalcopyrite, and tetrahedrite in brecciated quartz within altered mineralized quartz-carbonate veins. Halos are characterized by carbonatization, silicification, chloritization, and hematitization (Lafontaine 2007). One of the best drill results was an intersection of 18.7 g/t Au over 4.35 m (Fosters Resources 1995). Gold grades at Devil Pike gold deposit ranging up to 200 g/t have been reported in grab samples from mineralized bedrock exposed in trenches (PGE Resources Corp. 1993).

The Henderson Brook Project is another overlooked historical gold and silver discovery that is being explored by Geosearcher Inc. The silver, gold, and copper mineralization are occurring in a series of quartz veins along a north-south-trending, quartz-filled shear zone. The discovery vein system is about 6 m wide and is part of a large shear zone that cross-cuts a northeast-trending, intensely altered fault zone that also parallels Henderson Brook. The mineralization is hosted in Cambrian mafic volcanics of the Lawson Brook Formation. Faulted mafic and felsic volcanic rocks along Henderson Brook are intensely altered with sericite, carbonate, and fuchsite and are hematitized; all key indicators for orogenic lode gold (+silver+copper) deposits. Both this fault and shear zone are related to a terrane-scale fault, the Taylor Brook Fault.

The historical discovery was made by PGE Resources Corp. in 1989. Their grab sample from a 10 cm wide quartz vein within a 6 m wide vein system assayed 1182.86 g/t Ag, 0.55 g/t Au, and 0.79% Cu (Mineral Report of Work 473793 – PGE Resources Corp. 1989). Noranda then optioned this area along with a significant regional-scale package (see image 3). Noranda advanced the project and recommended that the property warranted follow-up work, which was never carried out. Specifically, that the Arseno Falls Au-As-Ag area should be trenched to asses the Au potential of the quartz-carbonate system (Mineral Report of Work 474086 – Noranda Exploration Corp. 1991). Their sampling HS6202 assayed 34.50 oz/t Ag confirming the high-grade silver (image 1). Several areas of interest were outlined on the claim group. The shear zone paralleling Henderson Brook is host to several As+Au soil anomalies and highly altered (sericite, carbonate, pyrite, fuchsite) outcrop and subcrop.
