Highland Copper Company, Inc. is rapidly approaching a crucial “go no-go” decision regarding the construction of the proposed Copperwood mine in the western Upper Peninsula of Michigan.

The mine requires between $391 million and $425 million in capital investment. As of now, none of that funding is formally committed.

So, how does a mining company find that much money? According to Highland's own assessments, they are pursuing several distinct financing options:

Commercial Bank Loans Conventional loans from banks that are experienced in the mining sector are a primary vehicle for funding mine construction, and Highland is pursuing debt financing. However, individual banks will limit their investment to no more than 40 percent of total project cost, and they will engage in vigorous due diligence before making a positive lending decision. They won’t jump in until Highland has secured other sources of funding that will get the project over the finish line.

The U.S. Export-Import Bank (EXIM) Loan The company is prospecting for a $250 million construction loan from the U.S. Export-Import (EXIM) Bank. The bank has indicated a willingness to consider this funding at favorable terms, but it comes with a major caveat: Highland must first pass a rigorous due-diligence process that includes a comprehensive environmental, technical, and financial review.

Department of Energy (DOE) and Department of Defense (DOD) Loans and Grants Highland is actively assessing loans and grants from federal agencies. Both the DOE and DOD view a domestic supply of critical minerals as a matter of national security. The DOD needs metals like copper for aerospace, munitions, and advanced electronics, while the DOE views copper as essential to modernizing the U.S. power distribution grid and hardening its energy infrastructure.

Offtake Financing and/or Royalty Streaming This involves selling future copper production or a percentage of future revenues in exchange for upfront cash. Highland has indicated it will appoint an "offtake advisor" to review the market and find partners. However, the company acknowledges that these agreements can be expected to pay only a small part of the massive $391 million to $425 million construction cost.

A Corporate Joint Venture Highland might try to partner with a well-established, deep-pockets player in the mining sector. In this scenario, a larger corporate producer would step in to manage both the physical construction of the project and the day-to-day operation of the mine.

Highland's cash on hand (approximately $20 million) will support the company's operations for 12-15 months, after which time it will need additional investment to continue as a going concern.

Here’s a recent update on the Copperwood project from Interlochen Public Radio.

Researchers are turning old maps into digital models of underground mines that were closed decades ago. The new technology could have global implications.

Here’s more on the story from Michigan Tech:

The Copperwood mine's short-term impact is undeniable: good-paying jobs and $12-15 million per year in state tax revenue, of which 65 percent would go to local units of government.

The long-term outcomes are harder to predict. Choices made in the next few years will determine whether the mine is a short-term boost or a long-term growth opportunity for the western UP.

I’m working with economic development experts to come up with a deep-dive analysis of how this might play out. This one may take a while, but stay tuned!
