The Cote Gold Project is an open pit gold mine located in the Chester and Neville Townships, District of Sudbury, in Northeastern Ontario. It is approximately 20 km southwest of Gogama, 130 km southwest of Timmins, and 200 km northwest of Sudbury, roughly 5 km west of Highway 144.
Exploration activities have been ongoing in the area since the early 1900s by various company and government agencies. More concentrated mineral exploration efforts were conducted in the early 1940s and from the early 1970s to about 1990. Since 2009, Trelawney Mining and Exploration Inc. had carried out exploration activities at the site. In 2010, the mine was discovered and extensive diamond drilling activities were undertaken to delineate the Cote Gold deposit. IAMGOLD acquired Trelawney Mining and Exploration Inc. in 2012.
TULLOCH Engineering was retained by IAMGOLD to prepare detailed design for 9 km of the Chester Road (the main access off the Sultan Industrial Road) reconstruction including 30 water crossings. The scope of work included drainage and hydrology studies, quantity calculations and applications to the Ministry of Natural Resources and Forestry for work permits. A close liaison had to be maintained with the Spanish Forest Sustainable Forest License Holder, EACOM Timber Corporation, to ensure all work was completed to the Ontario Forest Management Guidelines.
TULLOCH was retained again in 2012 for road design and water crossing drainage and hydrology for two additional access roads: Cote Lake and Three Duck Lake Roads. These two roads combined for approximately 8 km of road and 12 water crossings.
TULLOCH also completed an existing conditions survey and drawings of the Jerome Mine site, as well as general arrangement drawings for the installation of an all steel modular bridge over Ramsey Creek. The new 18.3 m permanent bridge structure would replace an existing temporary crossing providing full highway loading capability with improved lines of sight, resulting in a safer transportation route.
