Name of the Project
McIlvenna Bay underground copper/zinc project.

Location
East-central Saskatchewan, in Canada.

Project Owner/s
Foran Mining.

Project Description
McIlvenna Bay hosts one of the biggest undeveloped volcanogenic massive sulphide deposits in the region, with indicated resources of 39-million tonnes grading 1.2% copper, 2.16% zinc, 0.41 g/t gold and 14 g/t silver.

A feasibility study published in 2022 outlines that current mineral reserves would potentially support an 18-year underground mine operation capable of producing an average of 65-million pounds a year of copper equivalent.

Phase 1 entails the development of a decline/shaft underground mining operation using typical longhole mining methods for ore extraction with cemented paste fill replacement. 

Ore is expected to be processed through a conventional single-stage crushing circuit with a semiautogenous grinding mill and ball mill design. Grinding is planned to be followed by a flotation circuit to produce a copper and zinc concentrate for transportation from site to the Flin Flon area for shipment by rail for further refinement. A pyrite concentrate will be produced and introduced within the cemented paste fill for storage underground. The project is targeting an ore stockpile of about 275 000 t to support commissioning.

Foran is laying the groundwork for potential future Phase 2 expansion, which will leverage recent exploration discoveries at the Tesla and Bridge zones.
