Dr. Osvaldo R. Arce Burgoa


Osvaldo R. Arce-Burgoa, Geo. Engr. (UMSA, Bol.); Dr. of Eng. (Tohoku Univ., Japan); Fellow SEG, EE.UU.  

Geological consultant with more than 27 years’ experience on mineral exploration, mining geology and mining project evaluation in Bolivia and in several countries in South America, North America and Asia-Pacific. He visited projects and mines in more than 40 countries and has crossed both polar circles.  
Osvaldo Arce has a formation that includes studies such as: Doctorate of Engineering from the Tohoku University, Japan; Geological Engineering from San Andres University (UMSA) and Post-degree studies on International Management of Development Projects (IDB); Financial Analysis and Investment Operations Risks (Word Bank Institute, Queen's University), Management of Public Policies (JICA, Japan International Cooperation Agency); and other mineral exploration and Metallogeny courses in the US, Canada, Australia, Japan, Chile, Peru among others.
Early in his career (1984), he worked in COMSUR (Milluni mine) as a Mine Geologist, later in 1986 he joined the Japanese Cooperation Agency (JICA) as an assistant-researcher on mineral deposits. From 1992-1999 he worked first as Junior and then as Senior Geologist at EMUSA-ORVANA Joint venture (JV), being co-responsible for the discovery of the largest primary gold deposit in Bolivia (Pederson with 2.5 Moz Au). In 2000 he became the Exploration Manager of Sajama Bolivia -Peñoles JV; in 2001 he was Exploration Manager of Mitsui Mining & Smelting Corporation of Japan. In 2002 he was invited to take the position of National Director of the Geological Survey of Bolivia (SERGEOMIN). In early 2003 he was advisor to the Mining Corporation of Bolivia (COMIBOL). Between mid 2003 and late 2009 he returned to EMUSA as Exploration Manager and he leaded a geological team discovered more than 5 mineral systems (2 of them world class); later between 2010-2012 he was the Country Manager of Castillian Corp. Can.; between 2013 and 2015 he became the Executive Vice President of Feishang Corp. (E.M. Jacha Uru) with exploration and mine evaluations in Bolivia, Chile, Peru and Colombia. Currently, he is partner of Mining Company Antis SRL and technical advisor of the Canadian Eloro Res. Company based in Lima, Peru. Additionally, during his career he worked as a geological consultant for several international companies such as BHP, Newmont Corp., Placer Dome, Barrick Gold, GoldGroup, Dowa Mining, among others.
In the academic field he was an invited lecturer of Mining Geology at the Universidad Mayor de San Andrés; and also he taught Economic Geology and Geochemistry at the Technical University of Oruro; he authored the Mining and Metallurgy Engineering career at the Private University of Bolivia UPB and he was a speaker and instructor in several geoscience-mining national and international forums, mainly on promoting the geological-mining potential and Metallogeny of Bolivia. 
Between 2010 and 2017 he was elected President of the Geological Association of Bolivia (re-elected two times). During his presidency, three successful geological congresses were held and more than 40 training courses for professionals and students, inviting over 20 international instructors. Moreover, during his terms, the association acquired its first owned headquarters that have all the facilities including the Auditorium “Friedrich Ahlfeld” of 70 people in capacity.
Dr. Osvaldo Arce is Fellow of the Society of Economic Geologists (SEG); member of the Prospectors and Developers association of Canada (PDAC); Society for Geology Applied to Mineral Deposits (SGA); of the Geological Society of America (GSA); of of the Advisory Committee of “Geology in the Public Interest”; of the Colegio de Geologos de Bolivia; of the Sociedad de Ingenieros de Bolivia and member of the Academia Nacional de Ciencias de Bolivia. 
He wrote two books related to the geology and metalliferous ore deposits of Bolivia, referred to the last 40 years of geological-mining activity in the country and the second edition in English Language namely “Metalliferous Ore deposits of Bolivia” that summarizes the geology of Bolivia, a new classification of the ore deposit types in the country; descriptions and data of mineral resources of the more relevant deposits of Bolivia. Finally, he authored more than 40 technical articles published
