Our geological consultancy office has been founded at the end of 1978 by Adrian Baumer after 21 years of experience as staff geologist with hydropower plants in Switzerland and Australia, with a large mining project in Papua New Guinea and over three years as an economic geologist evaluating various mining prospects in the Western Hemisphere for a large US company.

As from 1.1.1996 our group operates as a public share company (Dr. Baumer SA, Geologi Consulenti).

The following list of recent reference projects refers to the more important of our activities essentially during the past 2-3 years, including some projects initiated previously:
