The Treasure of El Bagre

Last week I returned from my visit to the Colombian community of El Bagre, in the Department of Antioquia, where they depend almost entirely on gold mining for their subsistence income.

The hamlet of San Antonio is 2.5 hours from El Bagre, beyond the village of Zaragoza on a rocky, rutted road that becomes thick, orange muck when it rains, and it does so frequently.

As Zaragoza fell into the distance and jungle predominated once again, we stopped to speak with a woman knee-deep in a stream, mining for gold with her portable wooden sluice, a kind that many in Antioquia use. It was perhaps 10 AM and she told us it was the 5th location she had already worked that day.

Maria Eloisa Garcia has been mining this way for most all of her “62 or 63” years and her children and her children’s children are all miners as well. “It’s the only way we can make a living in Zaragoza”, she said.

Maria Eloisa’s husband sat on the bank while their dog barked at us and she lifted shovels full of sand and gravels from the bottom of the stream and dumped them into the top of her sluice. She scooped water from the stream with a sturdy home-made plastic bucket and poured it onto the gravel, working it by hand over the worn-smooth bottom of her inclined sluice. She watched carefully for any visible gold nuggets, then washed the minerals down onto the expanded steel mesh with carpet underneath to catch and hold any tiny gold flakes.

When she empties her sluice of the heavier minerals left in the carpet, she’ll carefully wash the fine gold out of the fabric into her batea (traditional South American carved wooden gold mining pan). Usually she’ll then add mercury to the concentrated mineral in her batea and begin to work the toxic liquid metal and the mineral sand together, rubbing, massaging, round and round, kneading the gold and mercury into a putty-like mass with her bare hands.

Maria Eloisa said she’s going blind and her husband appears to already be blind, both afflictions a likely result of having worked with mercury their entire lives. There is no insurance or health safety-net for artisanal miners. A 5oz vial of mercury was visible resting in her batea on the bank but she didn’t use the mercury while we were with her as many artisanal miners have become shy about acknowledging their use of it, knowing mercury will become illegal when the Minamata Convention on Mercury agreement goes into effect in Colombia in 2018.

Our visit to San Antonio had been pre-arranged by Lina Ospina, who works with an Alliance for Responsible Mining (ARM) project team there and when we arrived the community had assembled and were eagerly awaiting us.  The President of the mining community, Señora Dayanira, was the first to greet us and she immediately hugged me warmly, joyously. I had an overwhelming experience of having arrived home!!

Perhaps 50 people had gathered in an open-sided community hall, clearly excited that we had come to learn from them, to share about our project to discover a safe, affordable and highly effective replacement for mercury in their mining process and to find out if they would consider being a trial community to test the proposed solutions that arise from our Mercury Free Mining Challenge.

Their eyes brightened and they were clearly excited by the prospect of a clean, effective means of capturing gold, and while hopeful of a solution, they seemed most touched by the fact that someone from the more developed world was finally taking an authentic interest in what they care about.

The mid-day temperature was the typical high 90s, with humidity also above 90%, but the warmth of the people far outshined the thermal reading… jubilantly welcoming, excited and hopeful; many wanted to have their pictures taken with me and pleaded for my frequent return to their village.                   

Following the gathering, steaming dishes began magically appearing in the community hall from their nearby homes and hearts, feeding everyone a delicious and for me, a most memorable meal.

We then walked to the school to meet the children who took a break to gather and greet us.

Complete joy!!   The next time I feel discouraged about life, these children’s bright, expectant faces will be my beacon, reminding me that life is wonderful and it’s all possible!!

Some in the community said they feel all but abandoned by the government, except for rare police visits to enforce the mining regulations and check for guerilla activity. They feel resigned about ever having ready-access medical care, passable roads for transporting their crops to market, a sewer system or reliable internet access.

Both villages I visited, San Antonio and Puerto Claver, subsist on what gold the artisanal miners can collect from reworking the tailings (mine waste) of large-scale illegal mining activities of 5~ 20 years ago. The illegally mined land is a shockingly barren moonscape… massive mountains of bare, eroding orange soil linked to one another by a chain of stagnant red-brown to neon-green mine waste ponds, in ugly contrast to the surrounding verdant, bio-diverse and life-giving jungle.

The community of Puerto Claver is committed to mining responsibly and, with the support of ARM, has undertaken a project of reshaping and restoring the travesty left by the illegal large-scale mining operations. The Community Leader of Mining Operations there, Señor Aramis said they are returning their land to its original jungle contours, adding topsoil, fertilizer and planting trees, revitalizing the ugliness to its verdant beauty and diversity.  

The Mercury Free Mining Challenge (MFMC) is offering a $1 million prize to attract the world’s brightest innovators to discover a mercury replacement, solving one of the world’s most pernicious problems… mercury pollution. Challenges, incentivized by cash prizes are creating extraordinary breakthroughs and solving some of the most stubborn problems that humanity faces.

Artisanal subsistence miners are aware that mercury is deadly and they’d prefer to not use it, but mercury is the only known method available for them to capture fine gold particles somewhat efficiently. Mercury is estimated to be between 30 ~ 60% effective.

Both the Zaragoza communities I visited said they would be honored to be a test community for our mercury replacement trials when the discoveries are made.

We have an exquisite opportunity in the next 5~10 years to help transform the quality of life for the 100 million people globally whose lives depend on the artisanal gold miners.

We have the tools, the resources and the will to discover a safe and highly effective method for artisanal miners to capture gold, ending the annual release of 1,400 tons of toxic mercury and causing a breakthrough for humanity.

MFMC is raising awareness of the tragic circumstances artisanal and small-scale gold miners endure every day and through understanding, the global will to transform this intolerable condition will arise.
