The mine project planned by Canadian company Highland Copper has hit a snag. At a special meeting on Tuesday, Highland requested a $50 million performance-based Strategic Site Readiness Program grant from the Michigan Economic Development Corporation. Some of the board members of the MEDC expressed concerns about the project’s financing and referred the grant request back to the Finance and Investment Subcommittee for further examination. The main concern was whether outside financing would dilute ownership of the project. The mine project, if it goes through, is expected to bring in almost 400 jobs and $15 million a year in revenue.
