A study led by Elizabeth Holley, associate professor of mining engineering, is the focus of this article. Holley's study, originally published in the journal Science, focused on the critical minerals that exist in the waste streams of U.S. mining operations.

Maxwell Brown, assistant teaching professor in economics and business, and Angeline Letourneau, visiting teaching assistant professor in humanities, arts and social sciences, are interviewed about Xcel Energy's plans and how they could impact the utility's customers' bills.

Morgan Bazilian, director of the Payne Institute for Public Policy, co-authors this column looking at the role critical minerals play in the defense arena.

Angel Abbud-Madrid, professor of practice in mechanical engineering and the director of the Center for Space Resources, discusses the university's involvement with the development of a moon rover. The rover has been tested in a lab at Mines that contains simulated moon dirt, called lunar regolith.

Morgan Bazilian, director of the Payne Institute for Public Policy, notes a significant shortage of skilled workers in the energy, infrastructure, construction, manufacturing, advanced technology, and mining sectors could slow growth.

Elizabeth Holley, associate professor of mining engineering, is quoted about her study, published in the journal Science. The study examined the critical minerals that exist in mine waste being generated by mining operations in the U.S.

Freshmen and new graduate students to Mines carried on the tradition of bringing 10-pound rocks from their homes and placing them in the "M" that resides on Mount Zion. Stefani Tompkins, new Mines provost, is interviewed about the significance of the three-mile hike up to the mountain that happens at the beginning of every fall semester.

Elizabeth Holley, associate professor of mining engineering, led a study looking at obtaining critical minerals from currently-generated mine waste. With just a few exceptions, the study concluded the U.S. could obtain all the critical minerals it needs through the processing of its mine waste.

Elizabeth Holley, associate professor of mining engineering, led a study that looked at the potential of harvesting critical minerals from the waste streams at current U.S. mining operations. The study found that the U.S. could get most of the critical minerals in requires through this strategy.

A new study, published by the journal Science and led by Elizabeth Holley, associate professor of mining engineering, concluded that the U.S. could get most of the critical minerals it needs by processing the waste streams at current U.S. mining operations.
