The Dieu Merci mine is a historical and currently active mining site located in the commune of Saint-Élie in central French Guiana. It has a long tradition dating back to the gold rush era of the 19th century. Today, the mine is operated by the company Auplata and is known for implementing modern extraction technologies, including cyanidation processes to maximize gold recovery. The area is characterized by its isolated location deep within the rainforest, making the transport of equipment and personnel a significant logistical challenge. Dieu Merci produces gold from both primary quartz veins and alluvial deposits in surrounding riverbeds. In recent years, substantial investments have been made in infrastructure to increase efficiency while improving ecological standards. The mine is a key employer in the region and contributes significantly to the total gold production of the territory.

Where to view it

From the nearby hills or along the bank of the Cours d’Eau stream, one can gain an impression of the scale of the open-pit mining. A high point along the access road also provides a good perspective of the area.

Local products

In the region, one can occasionally buy handicrafts or jewelry made from local gold, as gold is the mine's main product. There are no direct sales points on site, but in larger towns like Cayenne, goldsmith works are sometimes available.

📆

Active season

The mine operates year-round, with activity potentially more intense during the dry season (August to November). During the rainy season, work is often restricted as roads and trails become difficult to traverse.

Nearby

A visit to the mine can be combined with a hike in the adjacent rainforest of the Guiana Amazonian Park. The nearby town of Saint-Élie also has a cultural contrast with its colonial buildings and local museum.
