Summary: petrography and other work from at least 67 countries,

and 14 Mexican states).

work and relevant analysed samples (including 3,622 detailed descriptions
in over 460 reports)
and not to the principal collection
of well over 2,500 in-house reference samples.
No equivalent comprehensive breakdown by commodity / purpose of
investigation is available at present, partly because these categories often overlap.

Ni-Cu-PGE (22%); VMS- sedex- porphyry- MVT- Ag (16%);
archaeology (8%);
