ASX-listed Intermin Resources and Focus Minerals have extended an exclusivity deed over the 2.1-million-ounce Coolgardie gold project, in Western Australia, by a further three months. The two companies in February announced a potential A$40-million asset sale agreement over the Coolgardie project, which includes the 1.2-million-tonne-a-year Three Mile Hill processing plant, which is currently on care and maintenance.
