A scoping study into the Mt Mackenzie gold project, in Queensland, has tapped a 300 000 t/y opencut mine as the most likely development option for the project. ASX-listed Resources and Energy Group on Friday said that the scoping study estimated that for a capital cost of A$13-million, the company could develop a gold mine producing an average 43 200 oz and 242 400 oz of silver over a 43-month period.
