Multi-Metal Development Limited (MultiMet) first originated as a Canadian natural resource exploration and development company called Mosquito Consolidated Gold Mines Limited (Mosquito). In 1991 management assumed control of Mosquito Creek Gold Mining Company Limited and its high potential Mosquito Creek Claim in Eastern British Columbia, hence its original name. Over the ensuing decade, Mosquito undertook a strategic program to purchase and option high-potential properties in low political risk environments in North America and Australia. In October 2012, the Company completed a management change with a newly elected board of directors and a new focus on its 100% owned CuMo Project, a massive Molybdenum, Copper and Silver deposit located in central Idaho, USA. The name of the Company was changed to American CuMo Mining Corporation to reflect this change and the importance of this world class project.

In 2021 MultiMet obtained the historic Bleiberg Mine in Austria.  Bleiberg is a former zinc, lead, germanium fluorspar deposit that has a strike length of 20 kilometers, Approximately 12 kilometers of the strike length has been mined for over the past 700 years.  MultiMet intends to focus on the remaining 8 kilometers of strike length.

In 2022 the name of the Company was changed Multi-Metal Development Ltd. to reflect the addition of Bleiberg and the wide variety of metals contained in the properties.

MultiMet is now diligently working on advancing its CuMo Project towards feasibility and developing the multi-metal Bleiberg Property in Austria, and is proud of its commitment to sustainable development together with environmental stewardship. With its open pit design and large economies of scale, the Company is confident of achieving its goal of establishing the CuMo Project as one of the largest and lowest-cost molybdenum producers in the world, as well as a significant producer of copper and silver. With a professional, dedicated team and new funding in place, management is confident that it is on the path of realizing the potential of the CuMo Project.
