Mining Technologies International (MTI) is one of Canada’s largest manufacturers and suppliers of mining equipment, MTI has constructed its own test tunnel on the west side of Sudbury Ontario at their Magill Street property. A natural rock outcrop provided the perfect spot to build a decline that will be extended underground to test its products in an actual working environment. The decline extends at a 15-per-cent grade. It is a 5.2-by-5.2-metre tunnel, the standard dimension of most Sudbury mines.
MTI has created a high profile project for local Mining Companies and suppliers to test and showcase their newly designed mine equipment and new technologies from various suppliers including Orica in an actual underground environment.
