Why Specialty Mining?

These elements and minerals are either found in small, scattered deposits that are difficult to access with traditional mining methods or they are present in ore bodies with low grades, requiring more specialized extraction methods. Specialty mining methods like borehole mining, solution mining, and in-situ recovery allow for more targeted, cost-effective extraction without significant surface disruption, especially in sensitive or remote locations.
