Dirty gold from Peru

LePictorium_0234869.jpg
In the Amazonian region of Madre de Dios in Peru, La pampa, a vast area devastated by illegal gold mining. The band follows the vein of the precious ore through the forest. Nearly 960 km2 of forest have been devastated in 30 years by the illegal exploitation of gold and contaminated with mercury. The area borders the Tambopata National Reserve where the miners broke in, destroying 7.95 km2 of forest, one of the richest in biodiversity.

In La Pampa, a forest of completely dead trees, contaminated with mercury. Illegal miners have left 30 km2 of excavations, sometimes 7 m deep, where all the organic matter in the soil has been leached and contaminated with mercury. During the rainy season, the polluted water seeps into the soil and into the many rivers, contaminating the fish consumed by the local population, especially the indigenous people who live along the rivers.

In La Pampa, in the region of Madre de Dios (Peru), illegal miners dug excavations sometimes 7 m deep, washing all the soil of its organic matter. Mercury-polluted "lakes" where nothing lives. On 100 km2 of old forest, there are now 30 km2 of new polluted lakes. During the rainy season, some of these lakes overflow. The polluted water seeps into the soil, even into the many rivers running through the region, contaminating the fish, which are very much consumed by the local populations, especially the natives living along the rivers.

On the site of La Pampa, the remains of makeshift plastic campsites. Until the beginning of 2019, 25,000 people lived on the La Pampa site, minors with women and children, in extreme conditions, without any health services. Many survived in wooden and blue plastic shacks, and moved around as the mining went on. A poor unemployed population, coming from the neighboring Andes, and completely forgotten by the central government, attracted by the prospect of finally getting out of misery with quick profits: income of 5000 soles per month (1330 €) when the minimum wage in Peru is 230 €. A whole clandestine economy - shops, hotels, bars, restaurants, brothels - generated by the mines had been set up with its cortege of nuisances: human trafficking, sexual exploitation of young minors, elementary human rights violated, alcoholism, arms trafficking, organized crime.

The entrance to one of the military bases on the outskirts of La Pampa. In February 2019, the Peruvian government dispatched 300 military, 1200 police, and 70 prosecutors for 14 days to hunt down illegal minors and regain control of the area. This operation, known as Operation Mercurio 2019, followed several smaller police and military interventions in previous years, which were unsuccessful. After recapturing the area, the government established three permanent bases at the gates of La Pampa, which are expected to remain there until 2021. Three hundred military personnel are responsible for preventing the return of the miners and dislodging those still there.

The shipment of plants leaves for the devastated part of the Tambopata National Reserve, under the watchful eye of the marines and rangers of the National Service of State Protected Natural Spaces (Sernanp).

In Mazuco, 120 km from Puerto Maldonado, capital of the Madre de Dios region, there is a nursery installed by the Centro de innovacion cientifica Amazonica (Cincia) where 14 species of trees grow. To restore the magnificent tropical forest of the Tambopata reserve, the Peruvian authorities made the crazy bet to reforest everything. These species were selected for their ability to grow in impoverished and degraded soil. The 140,000 seedlings will go to reforest the deforested lands of the Tambopata National Reserve. Experimental work began in 2016, with the financial support of the WWF (World Wildife Fund) and then the American agency USAID.

The shipment of plants leaves for the devastated part of the Tambopata National Reserve, under the watchful eye of the marines and rangers of the National Service of State Protected Natural Spaces (Sernanp). On a chaotic track, about 30,000 plants must be transported from the military entry post to the reforestation point in the Tambopata National Park . The 20 kilometers or so require 3 to 4 hours of motorcycle riding on a dirt track with rough wooden bridges. However, travel conditions have clearly improved. At the time of the occupation of La Pampa by the miners, it sometimes took a whole day to enter the heart of the area.

In the Tambopata reserve, destroyed by illegal gold panning, a reforestation program is underway, officially launched on December 5, 2019 in the presence of the President of Peru, Martin Vizcarra, and the Minister of the Environment, Fabiola Munoz. Approximately 40,000 seedlings selected and cultivated by scientists from the Centro de innovacion cientifica Amazonica (Cincia) are to be replanted in the reserve.

The soldiers are on mission in La Pampa for a month. In a few weeks, they will be called for other missions. Some of them are part of the Peruvian Army's Special Intervention Forces and are called to patrol territories controlled by drug traffickers. Another team will replace them. The Peruvian government plans to maintain this surveillance until 2021.

Departure on a reconnaissance mission at 3am. Illegal miners work a lot at night, taking advantage of the darkness to go unnoticed. Marines leave on patrol in the middle of the night to flush out miners at an operation they think they spotted a few days earlier. To locate them, the military sometimes use drones, spotting fresh motorcycle tracks or the sound of pumps used by the miners.

The military heard illegal miners fleeing on motorcycles. They are securing the area in case the minors return with weapons. However, most of the time, the miners flee, not without first hiding the motor of their pump at the bottom of the water, which they hope to retrieve once the soldiers have left. The soldiers are not supposed to arrest the miners. Their mission is to flush out the illegal operations and destroy the installation with explosives.

The Marines discovered this barge with miners working on it just before the arrival of the military. The ore, pumped from the bottom of the excavation, is washed and sieved on a mat to concentrate the gold. before being plunged into large drums containing liquid mercury that amalgamates the gold flakes. A large quantity of mercury - between 3 to 50g of mercury to obtain 1g of gold - is needed. Most of it is then disposed of in the excavation with the other mining waste. The water takes on a "chocolate" color, a sign of high mercury concentration.
