LOCATIONS OF TURNSTONE PROJECTS

Research and contract petrography,
analytical work, field projects

Summary: petrography and other work from at least 69 countries, with 50 jurisdictions in North America
(24 US states, 12 Canadian provinces and territories, and 14 Mexican states).
Note: this list refers to contract and research work and relevant analysed samples (including 3,751 detailed descriptions in some 500 reports)
and not to the principal collection of well over 4,000 in-house reference samples. It offers a good summary, but is somewhat out-of-date (2017).

No equivalent comprehensive breakdown by commodity / purpose of investigation is available at present, partly because these categories often overlap.
A partial survey of over 2,000 thin-sectioned samples suggests the following: gold (48%); Ni-Cu-PGE (22%); VMS- sedex- porphyry- MVT- Ag (16%);
archaeology (8%); rare metals, gems and industrial minerals (3%); meteorites (2%); other geology (1%)
