Fireweed Zinc foresees a solid year of drilling at its Macmillan Pass project in Yukon, Canada, as it works towards completing resource and preliminary economic assessment updates in early 2023, president and CEO Brandon Mac-Donald told Mining Journal at the 2022 AME Roundup in Vancouver, Canada. MacDonald said that drilling success last year, with the discovery of a previously unknown mineral horizon above the massive sulphide Boundary West area, was leading the company to adopt a more data-driven approach to exploration.
