It's true that the company hasn't placed much focus on zinc, or lead either. However, both are significantly abundant at what may be primarily copper mines, zinc in particular. In fact, and pound for pound, there may be as much or more zinc at Hay Mountain as there is copper.

This makes the increasing scarcity of zinc (and the consequential price rises) very worth watching, I would think.

Then, there should also be more than a few by-products from a mine at Hay Mountain that have also not received much attention. Among these we may find selenium, tellurium, and even some platinum group elements. Income from by products may not be large, comparatively speaking, but they can go a long way toward offseting operating costs.
