Alain Lambert

More than 35 years of experience in the field of mining exploration, mainly in exploration geochemistry
.
Activities in several continents, especially in Latin America (8 countries), Africa (12) and Asia (5), as mission header or geochemist expert.

Types of intervention:
• All phases of geochemical exploration: definition of methodology according to the context, programming, follow-up, interpretation of results and integration in SIG via databases for multicriteria treatments. According to the cases, the objectives were 1) regional mineral inventories, 2) stream-sediment and/or soil sampling, 3) assistance to geological mapping.
• Training of local teams on the theoretical and practical level in French, English and Spanish;
• Follow-up surveys;
• Geological cartography;


Principal substances: gold, base metals, bauxite, uranium.

Mines put in exploitation after intervention: Léro (Guinea, gold).
Mines-extension exploration: Ariab (Sudan, gold); Ity (Ivory Coast, gold).

Geochemical exploration at regional or detailed scales:

Gabon (SYSMIN project, 2006-2008), Mali (area of Nioro of the Sahel, 2006, inventory), Sudan (Red Sea Hills, 2001, gold), Saudi Arabia (Barah, 1999, gold -BM), Argentina (Cordoba, 2000, inventory), Bolivia (Escala, 1999, gold -BM), Ivory Coast (Ity and Toulepleu, 1994-96, gold; Katiola; Niofoin; Bondoukou…), Chile (V and Xème region, 1992-95, inventory), Kolar (India, 1993, gold), Ghana (Bui, 1991, gold -BM), Malaysia (Betis, 1990, BM), Yemen (project NW, 1984, inventory), Uruguay (1981-82, uranium), Colombia (several areas, 1980-81, U), Costa Rica (Talamanca, 1973-76, BM) .........
Work performed most generally: analyzes for gold and multielements, treatment and interpretation of the results, selection of targets, report, synthesis.

Explored deposits in follow up (soils survey, trench, drillings): Ity mine
extensions (Ivory Coast, gold), Dorlin (Guyana Fr, gold), Migori (Kenya, BM), Ayé Koyé (Guinea Conakry, bauxite), Irian Jaya (gold, BM), Zalim (S. Arabia, gold).

Geochemical interpretation without intervention in the field: Italy (Peloritano, inventory), 12 1:50 000 scale maps in France (National mining Inventory, 1985-90), data from many strategic and tactic prospection, harmonization of data, various synthesis (France, Gabon, French Guyana …).

Other interventions in the field “geochemistry”:
- creation of databases, (mining inventory France - >300 000 samples, idem Guyana - >60000 samples, Mali: >220000 soil samples, Gabon…) ;
- harmonization of geochemical results for synthesis maps;
- integration in SIGs;
- integration of geochemical data in Web sites for diffusion
( http://gisguyane.brgm.fr ; http://sigminesfrance.brgm.fr ).

Written/spoken languages/: French, Spanish (fluent), English (good), Portuguese (basic).

Software used: ArcGis (constantly), GDM, Access, Excel, MapInfo.

School: University of Paris 11 (Orsay): doctorate, thesis of petrography and volcanology (Cantal, 1969).
Baccalaureat: Mathelem (1962).

Organizations:
1983-2008: BRGM
1980-1983: Cogema
1972-1980: Alusuisse Mines
1970-1972: Ministerio de Minas de Costa Rica.
