It should be stated that, with the exception of gold and some silver,
little is mined. The deposits of coal, petroleum, copper and silver
have thus far yielded, under present methods of management, outputs
of no commercial value.

However, anthracite is found at Santa Maria Dota, Department of
Puriscal. A specimen of it, analyzed by Dr. L. J. Mátos, chief of
the laboratories of the Philadelphia Commercial Museum, gave these
results:

It is a good quality of anthracite coal and compares very favorably
with the best grades that are mined in Pennsylvania. Color, black;
slight tendency to show iridescence; fracture, conchoidal, brittle;
analysis, specific gravity, 1,343; weight per cubic foot, 83.93
pounds.
