R.A.F. Penrose Gold Medal
The R.A.F. Penrose Gold Medal was established in 1923 to be awarded primarily in recognition of a full career in the performance of "unusually original work in the earth sciences," which shall be broadly interpreted to encompass major contributions to (a) the science through research, (b) the profession through teaching, program administration, and development of exploration technology, and (c) the development of mineral resources through mine geology, exploration, and discovery.
The medal may be awarded annually, but no less frequently than once every three years. A nominee for this honor need not be a member of the Society. Visit the Medals and Awards page for nominating instructions.
