Multi Metal Development Limited (MultiMet) (formerly American CuMo Mining Corporation) is a Canadian-based mining company directed by industry experts with more than 260 years combined environmental policy, regulation, permitting, compliance, geological exploration, mine planning and sustainable development expertise. MultiMet is currently advancing two projects—the world-class CuMo Project in Idaho  and its newly-acquired Bleiberg Project in Austria. MultiMet’s commitment to responsible practices and sustainable development drives each project decision to optimization through innovative solutions.

Developing the largest un-mined molybdenum deposit in the world

MultiMet has discovered one of the largest deposits of molybdenum, copper, silver, tungsten and rhenium in North America near Boise, Idaho, USA. The CuMo Project is advancing towards feasibility with the goal of being one of the world’s largest and lowest-cost primary producers of molybdenum

MultiMet is the largest Shareholder in Idaho Copper Corporation which owns a 100% of the CuMo Project, which is not only rich in molybdenum, but also contains very significant credits of copper, silver, rhenium and potentially tungsten; in fact, enough rhenium (critical USA minerals) to make it the largest in the USA and enough silver to place it among the Top 25 silver deposits.

The CuMo Project has two distinct layers of diversification: the upper half contains higher grades of silver and copper compared to molybdenum; the lower half is rich in molybdenum, with lower grades of silver and copper. The total recoverable value of both layers is what gives the CuMo Project such excellent economic potential. An independent NI 43-101 preliminary economic analysis prepared June, 2020 shows a production life of 30 years with an average annual undiscounted after-tax cash flow of slightly over US$370 million, with substantial room for improvement as various optimization techniques are applied. The CuMo Project is in a politically stable location in an area heavily mined and logged over the past 100 years.
