Background

Rainy River Resources is focused on exploring and developing a newly discovered gold resource in the southwest corner of northern Ontario. The company’s key asset is its large 100%-owned advanced exploration stage Rainy River gold project.

TBT Engineering’s Role

TBT Engineering was commissioned by Rainy River Resources Limited to provide a Feasibility Study for the construction of a proposed realignment for an existing transportation route. The current route traverses through a mineral exploration area being developed by the company and is located near a community, which has raised safety concerns.
