Discussions commenced with metal traders and smelters regarding offtake for Superior Lake Zinc Project

Critical Minerals & Rare Earths


  • Discussions with multiple global metal traders and smelters have commenced regarding future offtake for the zinc and copper concentrates to be produced at the Superior Lake Project 
    • Forecasted annual production of 69,819t of Zn and 5,308t of Cu concentrate per annum.
  • Both the zinc and copper concentrates are of a high quality with favorable grades and minimal deleterious elements (Table 1 and Table 2)  
  • The Project has established transportation routes to North American and international smelters, giving the Project its unique location 30km from an operating rail terminal (Image 1)  
  • The market outlook for zinc is strong, due to declining production from existing primary zinc mines, and increased forecasts on long-term demand driven by decarbonization 

May 31, 2022 (Source) – Metallum Resources Inc. (TSXV:MZN) (“Metallum” or the “Company”) is pleased to announce the commencement of discussions with multiple global metal traders regarding future offtake from the Company’s Superior Lake Zinc and Copper Project (“Project”) in Ontario, Canada.

Preliminary discussions with a number of these groups have indicated a willingness to have offtake linked to additional funding solutions. An offtake related financing is typically in the form of mezzanine debt or concentrate pre-payments.

The concentrate produced at Superior Lake can access smelters using existing rail and road infrastructure to North American smelters as well as smelters in Asia, using the Vancouver port. The Thunder Bay port, which is located 214km from the mine gate, will provide access to smelters in Europe. The Project’s unique location and access to the Canadian rail and highway network will provide access to Canadian port systems, both East and West coasts, allowing easy access to major smelters around the globe.

Both the Zinc and Copper concentrates are well understood given the Project successfully operated for a decade before closing in 1998 due to sustained low zinc prices. This historical production as well as additional metallurgical test work carried out by SGS Lakefield in Canada (Superior Zinc and Copper Project Feasibility Study N.I. 43-101 compatible, DRA – October 2021), provides detailed information and certainty to these groups. Detailed information regarding the concentrate grades and quality can be found in Table 1 below.
