Round Top Rare Earth and Critical Minerals Project

A revised preliminary economic assessment (PEA) for the project was completed in August 2019. It predicts a 16-months payback period for £269m ($350m) initial capital investment on a 7.3 million tonnes per annum (Mtpa) open-pit mining and processing operation that can produce 2,212(t) of rare earth oxide (REO) as well as 8,956t of lithium carbonate annually over a mine life of minimum 20 years.

Mining and Using Minerals

Geologists look for mineral deposits that will be profitable to mine. Ores that are close to the surface are mined by surface mining methods. Ores that are deep in Earth are mined using underground methods. Metals ores must be melted to make metals. Many gems are cut and polished to increase their beauty. Minerals are used in a variety of ways.
