Minto Metals Corp operates the underground copper-gold-silver mine located in central Yukon, approximately 240 kilometres north of the capital Whitehorse along the Klondike Highway. In excess of US$350 million of capital expenditure has been invested into Minto operations since site construction began in 2006. The Minto mine was in continuous production between 2017 and 2018, when the mine was placed onto temporary care and maintenance. Pembridge acquired Minto from Capstone Mining Corporation in June 2019 and recommenced operations in October 2019.  On 29 November 2021, Minto Metal Corp listed in its own right in Toronto on the TSX Venture Exchange (“TSXV”) under the symbol “MNTO”.

Minto Explorations Ltd. was incorporated in 1993 and acquired the Minto Project from a syndicate consisting of ASARCO LLC and Falconbridge Ltd., in the early 2000s. Sherwood Copper Corporation later acquired Minto Explorations Ltd. in 2005 and financed the development of the project into an operating mine. The first copper concentrate was shipped in the summer of 2007, and just over 12 months later in November 2008 Capstone acquired Sherwood Copper Corporation.

The Minto Mine started out as an open-pit operation, supported by concurrent underground operation from 2014. The open pit operations were then permanently closed in Q2 2018 with ore now being exclusively mined from underground. In October 2018, the operations were placed on temporary care and maintenance. In June 2019, Pembridge Resources completed the acquisition of Minto and 4 months later, in October 2019, recommenced operations.
