A Highland Map of Lake Superior Mining

It would be instructive to lay this map, published today by Highland Copper, over the map of Mines, Mineral Exploration, and Mineral Leasing around Lake Superior published in 2013 by the Great Lakes Indian Fish and Wildlife Commission.

Having acquired all of Rio Tinto’s exploration properties in Michigan’s Upper Peninsula, Highland now dominates sulfide-mining exploration in the UP.

A multi-billion dollar mining behemoth like Rio Tinto could arguably have left these copper, zinc and gold sites idle for a rainy day. The same can’t be said about a junior like Highland. With market capitalization of $62 million, the company paid $2 million at closing, leaving its subsidiary on the hook for an additional $16 million (in the form of a non-interest bearing promissory note), to be paid in regular installments.

According to company’s own press release, “the payments…will be accelerated if Highland publicly releases a feasibility study covering any portion of the UPX properties.” So once exploration begins with test drilling in 2018, we might see efforts to expedite permitting and development for these sites.

If UPX succeeds in taking even a fraction of these sulfide-mineral deposits from exploration to development, and if these new mines are developed under the pressure of an accelerated payment schedule, the risk to the Lake Superior watershed will be significantly heightened.
