Among the glaciers and turquoise fjords of southwestern Greenland, a mining company is betting rock similar to the one the Apollo missions brought back from the moon can address some of Earth¡¯s climate change problems.

¡°This rock was created in the early days in the formation of our planet,¡± says geologist Anders Norby-Lie, who began exploring anorthosite at the remote mountain landscape in Greenland nine years ago.

More recently, it has excited mining companies and investors hoping to sell it as a relatively sustainable source of aluminum as well as an ingredient to make fibreglass.
