Gold mining in Montagne d'Or, Guyane (France)

The Montagne d'Or mine is one of the largest open cast gold mine projects in the French Guiana and in the world. There is a strong dispute on this project, with President Macron in favour of it.


NO to huge industrial gold mining project in French Amazon. [2].  According to the strong social movements against gold mining in Guyane (a French territory in America), Alexei Mordashov, the Russian billionaire and owner of mining company Nordgold, remains more than ever determined to launch a most destructive gold mining project “Montagne d'or” (Gold mountain) [2].  Given the delays in the investigation and public inquiry foreseen, the authorization to operate the mine could be granted in 2020, and production could begin in January 2022.  By 2017, President Macron of Minister Nicolas Hulot of France appear to take opposite views on the issue,  Macron in favour and Hulot against it. Guyane is to all effects a French colony in Amazonian territory in America.

Project Details and Actors
Project DetailsThe 4.8 million ounce of Montagne d’Or gold deposit is located in north-west French Guiana, 180 kilometers west of the capital, Cayenne, and 80 kilometres south of the department capital, Saint-Laurent-du-Maroni. In mid-March 2017, Nordgold acquired a 55 % interest in the Montagne d’Or project. Nordgold also holds ~9% of Columbus Gold Corp, the main partner in the Montagne d’Or project. Sources state that the project is anticipated to produce 237,000 oz of gold a year in the first ten years at an average grade of 1.73g/t. The overall mine life is expected to be 12 to 15 years.[5] The Montagne d’Or mine is a part of the Paul Isnard project, which comprises eight mining concessions spanning 190km².

Columbus Gold holds a 45% interest in the Montagne d’Or mine, while Nord Gold (Nordgold) holds the remaining 55% stake.

The mineral deposits of the Guiana Gold Belt are very similar to those in other greenstone terrains such as in West Africa. According to the company, this will enable Nordgold to apply its deep knowledge of West African geology to the Project and other projects in the region. Columbus Gold, with its many years of operational experience in French Guiana and unique local knowledge will serve a strong partner in the advancement of the project, according to the company's own view. The project is now in the phase of exploration, pending a commision on inquiry. [1]

Other Comments"Ce qui occupe le cœur des débats en Guyane actuellement est encore très peu discuté en métropole : il s’agit d’un projet de mégamine d’or à échelle industrielle et à ciel ouvert, la Montagne d’or. Ce projet titanesque promu par des entreprises étrangères se situe entre deux réserves biologiques intégrales, en pleine forêt amazonienne. Cette mine est la caricature d’un projet du passé. Si elle voyait le jour, elle serait la plus grande mine d’or jamais réalisée en France. Elle met en danger la ressource en eau de l’ensemble du bassin de Guyane, elle nécessite une déforestation et une matrice énergétique génératrices de CO2, elle engendrerait des pollutions inévitables au premier rang desquelles la cyanuration".
