This second volume of Novel Methods and Applications for Mineral Exploration was prompted by the great success of the first issue and the sustained interest of the exploration community. It is a brief but representative cross-section of the exciting developments in our understanding and practice of mineral exploration in areas such as geophysics, computational methods (specifically artificial intelligence and computer learning), and the development of novel analytical methods. As such, it will no doubt be highly useful, interesting, and thought-provoking for both the academia-based and the practicing exploration geologist.
