What Is: Mining?
Mining is defined as the extraction of valuable minerals or other geological materials from the earth. The history of mining in Portland, and its prospectors is a story of adventure, discovery and dreams. Minerals found in Portland were quickly recognised as precious resources which promised huge financial gains. Inhabitants of Portland were driven by determination and they dreamed of better lives. Modern mining processes practiced in Portland involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials and finally reclamation of the land to prepare it for other uses once the mine is closed.
