Summarize your company business and current projects you are involved in.

We are an Innovation provider & have Innovated a “TRAP” to eliminate Mercury (Hg) used in ASG gold (Au) miner’s ore processing & eliminate cyanide (CN) used to process tailings to recover more Au safely & sustainably. We are raising Impact Capital to fund the implementation of our “TRAP” to prototype the world’s 1st Hg-free ore processing CN-free tailings remediation minerals reclamation pilot plant in Zaruma Ecuador, 1,200 meters high in the Andes & site of deadly ongoing Hg discharge.

What is the TRAP you have Innovated?

I’ll preface my answer by quoting a statement from an article,

“A review of the failed attempts to curb mercury use at artisanal gold mines and a proposed solution” wherein which the authors wrote, “Governments, international agencies, NGOs, and academics focus their projects’ objectives on monitoring mercury pollution in Artisanal Gold Mining (AGM)”.

“Rarely do these monitoring projects propose solutions to eliminate the use of mercury in AGM. Rather, they focus on the assessment of associated health or environmental impacts, demonstrations of cleaner techniques to extract gold and legal actions to formalize artisanal miners”.

“Those approaches have not resulted in mercury reduction or elimination.”

Marcello M. Veiga, Ph.D., Professor Emeritus Norman B. Keevil Institute of Mining Engineering, University of British Columbia (UBC), co-Author of the article, and a world-renowned global authority on artisanal and small-scale gold mining (ASGM) has graciously provided us with a wealth of information and knowledge derived from his 40+ years of intensive research and field projects across 35 countries.

Marcello detailed an Innovative process to leach gold (Au) safely and sustainably from ore and from tailings waste using the cassava plants free cyanide (CN) extract as a lixiviant finalizing our Ecuador TRAP (Tailings Remediation Action Plan) Innovation.

The TRAP combines the use of cassava extract as a lixiviant, an idea developed by Marcello who along with Pariya Torkaman conceived and coordinated the experiments, with conventional mechanical processes using gravity and centrifugal force to capture fine Au concentrate after milling or from tailings ponds waste.

This data was detailed in their Publication “Leaching gold with cassava: An option to eliminate mercury use in artisanal gold mining”.

The use of cassava is proven and scientifically documented to recover more Au safely and sustainably than cyanidation or Hg-amalgamation.

Bitter cassava, a cyanogenic plant is common in many Latin America ASG mining areas and is used to manufacture flour “manipueira” and make tapioca which in Brazil, is used to make beer.

“Bitter cassava has been sustaining millions of people in the world who produce flour. The symbiosis of artisanal flour producers with artisanal gold miners can be a win-win solution to reduce pollution from both sides.”

According to P. Torkaman et al, when crushed “the cassava plant liquid extract “contains hydrogen cyanide (HCN) generated from the hydrolysis of non-toxic cyanogenic glycosides” which are substances intrinsically. These plants do not contain cyanide, but they generate it as a defense mechanism to intruders.

The free CN expelled liquid from the bitter cassava plant represents 30 – 40% of the root weight. The indigenous name for this fluid is “manipueira” in Brazil.

When used in the leaching process, the gold particles in the ore are exposed to the free cyanide from the cassava liquid. In an oxidizing environment, created by intense agitation, gold forms a soluble complex with cyanide.

Published Au recoveries in 24 hrs. were 70% for 10 gms. of ore + 25 mL. of “manipueira” (30% solids/liquid (S/L)), and 85.7% with S/L = 20%. A 10% reduction in the S/L with the addition of more manipueira contributed to a 10% increase in Au recovery.

Using “a high concentration of cyanide 5000 mg free CN/L, the gold extraction reached more than 95% in 24 hr.”

Bitter cassava has been sustaining millions of people in the world who produce flour. The symbiosis of artisanal flour producers with artisanal gold miners can be a win-win solution to reduce pollution from both sides.

Cyanide Concentrations in Selected Plants

It has been estimated that 16 million artisanal miners produce between 380 and 450 tonnes/annum. of Au in more than 70 countries which represents 10–15% of the total world Au production collectively discharging to the waters and vaporizing to our biosphere 2,000 tonnes of Hg per annum.

The TRAP Innovation is application ready to implement to prototype the world’s 1st Hg-free ore processing tailings remediation minerals reclamation pilot plant in the Portovelo-Zaruma mining district Ecuador using the cassava plant extract as a lixiviant proven to recover more Au than using either cyanidation or Hg-amalgamation, and conventional mechanical processes concentrating Au for direct smelting.

“We propose to use a solution extracted from plants, bitter cassava, as a gold leaching lixiviant for the first time in the history of the mining industry.” Marcello M. Veiga, Ph.D.

How do you prototype the world’s 1st Hg-free organic CN processing pilot plant?

We intend to Acquire/Joint Venture one of the 65 APROPLASMIN Members 87 whole-ore Hg-amalgamation cyanidation Chilean processing centers located in the Portovelo-Zaruma mining district.

We intend to install low-cost Icon 150 (i150) gravimetric concentrators (centrifuge) with an operating capacity of 2 tons/hr. to concentrate the collected Au in the milled ore slurry.

The (i150) will replace the Chileans mills inefficient and cumbersome pair of balleta (wool carpets) lined sluices, and toxic Peter plate sluices; stacked copper (Cu) plates hand covered in Hg both used to concentrate Au will be removed from the center.

The i150 uses enhanced gravity up to 200 G’s to concentrate the ‘free’ heavy minerals recovering fine Au down to 400 mesh (37 microns) from tailings and milled ore.

The i150 is also known as a centrifugal concentrator because of the centrifugal action of the spinning bowl. The process uses only water and an electric motor to concentrate the precious heavy minerals from a slurry.

A Chilean mill processes hand shoveled ore at an operating capacity of ½ ton per hr. 

We intend to couple 3 Chilean mills to each i150 to increase the processing volume.

We intend to install renowned Gemeni tables known to generate a bullion grade Au product from low-grade concentrates at high recoveries.

Gemini tables have a unique table design which allows for the production of an Au concentrate that can be directly smelted to bullion which will be used to process the i150 Au concentrate to remove the free Au.

We intend to replace the use of Hg in whole-ore Hg-amalgamation Chancha barrel processing with cassava extract which will recover more Au safely and sustainably mitigating any further human health threats and environmental damage.

Hg used in whole-ore Hg-amalgamation Chancha barrel processing discharge to the rivers is one of our planet’s deadliest source of Hg pollution.

ASG miner’s Hg vaporization of Hg to our biosphere is our planet’s 2nd deadliest source of Hg pollution.

We intend to install 4’x 8’ shaker tables with an operating capacity of 2,000 – 2,500 lbs./hr. to remediate existing unmanageable tailings ponds to reclaim unprocessed silver (Ag) for profit after cassava processing to recover Au as ASG miner’s consider Ag a contaminant.

Shaker tables are proven to recover up to 95%+ of the tailings spent Hg safely and sustainably for safe and proper disposal mitigating any further human health threats and biodiversity destruction.

5 years ago, your company had a JV in the Bella Rica mining district Ecuador. Why did you switch from underground hard rock mining to processing tailings?

June 30, 2015, Bruce & Alexandra Cosgrove incorporated Alchemy Mining Group, Inc. (“AMGI”), a for profit benefit corporation with a mandate to provide Innovative green gold mining solutions to the Hg-dependent ASGM sector. 

During March 2017, we coordinated and executed a Joint Venture Agreement by and between AMGI and Alquimia y Explotación Minera San Juan Alquiexmi S.A., a newly  incorporated Ecuadorian Jr. mining company having granted mineral rights on 2 concessions in in the Bella Rica mining district Ponce Enríquez Ecuador, one of which concessions had been artisanally mined producing Au buttons since 2012.

During 2018, we discovered about the decades of ongoing human and developing children in utero health threats, and biodiversity destruction caused by ASG miner’s ore processing in the Portovelo-Zaruma mining district since the 15th century where the ore from our concession would be processed hence, we pivoted our focus.

Continuing on researching green Au mining solutions, we discovered that in the Portovelo-Zaruma mining district 1,200 meters high up in the Amazon Andes was responsible for the annual discharge of millions of tonnes of toxic tailings wastes from 87 whole-ore Hg-amalgamation Chilean processing centers operating in 2020 (110 in 2010) lined up along one sq. mile on the Calera and Amarillo Amazon River banks ultimately emptying into the Pacific Ocean.

In 2019, we embarked on a mission to acquire or JV one of the 65 APROPLASMIN Members 87 Chilean processing centers and convert it to the world’s 1st Hg-free ore and tailings processing center using the cassava plant extract, gravity, and mechanical equipment all combined in a single.

The ongoing discharge and vaporization of deadly neurotoxin Hg by ASG miner’s all largely having undiagnosed Hg poisoning has killed all their local biota life, contaminated their drinking water, polluted their soil destroyed their crops, and polluted  their biosphere.

Our Innovation was born from our necessity to find a solution to eliminate Hg use in ASG miner’s ore processing to mitigate further human health threats and local terrestrial species and biodiversity destruction which we have found and are application ready to  implement our TRAP Innovation to #MakeMercuryHistory in ore processing.

Why is it so important to eliminate miner’s use of Hg and CN?

Hg-dependent ASGM is the Planet’s largest Anthropogenic [man-caused] source of Hg pollution, a deadly neurotoxin primarily due to India and China’s ever growing Au demand for jewelry gold (“Au”), and consumer demand for electronics Au.

Mercury is ubiquitous, naturally occurring, and persistent exposure can cause acute and chronic intoxication at low levels of exposure.

The WHO considers Hg as one of the top ten chemicals or groups of chemicals of major public health concern on the Planet.  Most ASG miners suffer from undiagnosed Hg poisoning.

The UN Environment has classified Hg as a neuro-, nephro-, & immunotoxic, a “chemical of global concern” owing to its long-range atmospheric transportation, persistence in the environment once anthropogenically introduced, ability to bioaccumulate in ecosystems and its’ significant negative effects on human health, and our environment.

Upon skin contact and/or inhalation, mercury and Methylmercury will damage the central nervous system, kidney, spleen and penetrate the blood brain barrier causing health deterioration, ataxia along with numerous other symptoms, and the blood placenta barrier causing developing fetus deformation and retardation.

Hg is converted to MeHg principally by fluvial dispersion of contaminated mineral processing wastes throughout the Amazon continuing through Peru to the Pacific Ocean, and the recycling of Hg sublimated during the burning of the amalgam which is transported by wind currents and deposited around the world documented by the Oxford University earth scientist to stay airborne up to one year making Hg pollution a global issue.

According to the environmental-health organization IPENnew research shows “island territories around the world are drowning in Hg pollution that has leeched deep into their coastlines, and could last generations.

Women of childbearing age around world suffering toxic levels of mercury. Study finds excessive levels of the metal, which can seriously harm unborn children, in women from Alaska to Indonesia, due to gold mining, industrial pollution and fish-rich diets.”

Approximately 20 million impoverished ASG miners including ~ 4.5 million women and ~ 600,000 children under the age of 15 all largely having undiagnosed Hg poisoning directly impact 100 (one-hundred) million people in 80 (eighty) Countries from their use of deadly neurotoxin Hg in Au-ore processing.

High level exposure to Methylmercury is known as Minamata disease previously, Chisso-Minamata Disease, strange disease, sauntering disease, ominously, “dancing cat disease”.

Impoverished ASG miners produce ~ 20% of the world’s Au supply for jewelry and electronics Au for a meager pittance of several dollars per day to support a family of 4 – 6.

The BIODIVERSITY RESEARCH INSTITUTE (bri) data presented here emphasize the global distribution of marine and freshwater fish, sea turtles, seabirds and other avian species that forage in coastal areas, and marine mammals. Thresholds shown are for human health dietary purposes, except for birds which reflect reproductive harm.

Why did you pick Zaruma?

I’ll answer the question with a question.

Did you know the Tuna fish you eat caught in the Pacific Ocean is poisoning you with deadly neurotoxins Hg & methylmercury (MeHg) both of which bioaccumulate up the fish food chain caused by ASG miner’s ore processing high up in the Amazon Andes in the Portovelo-Zaruma mining district Ecuador where Au has been mined since the 15th Century?

This deadly toxic pollution comes from 65 APROPLASMIN Members 87 Chilean Hg and CN ore and tailings processing centers 1,200 meters high up in the Amazon Sandes mountains.

According to Adriana Gonçalves et al 2015 research study, there were 240 Au mine concessions and 87 Hg-amalgamation Chilean processing centers with 78 licenses lined up along one square mile of the Calera and Amarillo riverbanks in Portovelo-Zaruma area each processing ~ 1,860 tonnes of ore/month to produce a “reported” ~ 5.7 Kg of Au/month using ~ 2.4 Kg of Hg/month/center and ~ 2.05 tonnes of CN/month/center.

These centers process 10,000 local ASG miners and 40,000 neighboring miners ore and tailings representing one of the highest density of miners and processors a reason we judiciously choose Zaruma, the apex of Hg pollution.

In 2015, these centers Collectively discharged 1.9 million tonnes/annum (1.7 million in 2013) of toxic heavy metals chemicals tailings surface sludge including 222 kg of deadly neurotoxin Hg providing mobility for Hg, and 2,033 tonnes of toxic CN, Nitric Acid, and other toxic ore-related elements including arsenic (As), cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) polluting the Calera and Amarillo rivers.

Hg is a precursor to an even deadlier deadly neurotoxin than Methylmercury (MeHg, and with unknow biomagnification effects.

Hg is converted to MeHg principally by fluvial dispersion of contaminated mineral processing wastes by anerobic microbes in a moist environment and by human sweet, touch, or inhalation.

This deadly toxic pollutant discharged from the Zaruma processing centers zig-zags throughout the Amazon rivers to Peru’s Puyango-Tumbes river basin resulting in an internationally supported law-suite against Ecuador for decades of ongoing human health threats, loss of drinking water, & terrestrial species loss, and biodiversity destruction with estimated damages at $USD 35 Billion.

The pollutant continues zig-zagging the Amazon rivers polluting soil, poisoning the rivers  to empty in and pollute the Pacific Ocean.

December 17, 2020, UK Super Rock Star @robbiewilliams reported he ‘almost died’ from mercury poisoning over seafood habit.

Vaporized Hg is transported by wind currents and deposited around the world documented by the Oxford University earth scientist to stay airborne up to one year which is then deposited in rivers, lakes, and on land.

The implementation of the TRAP will start at the pinnacle source of mercury pollution in Zaruma. It doesn’t get any higher than that.

We are allocating 3% of Net proceeds from operations to develop and implement a plan to detoxify the ~ 40,000 residents of the Portovelo-Zaruma mining district in our attempt to #MakeMercuryHistory in ore processing.

Our Innovation was born from our necessity to find a solution to eliminate Hg use in ASG miner’s ore processing to mitigate further human health threats and local terrestrial species and biodiversity destruction which we have found and are application ready to implement our TRAP Innovation to #MakeMercuryHistory in ore processing.

How are you accomplishing this undertaking, and what’s the current status?

We have assembled a Team of specialists including; Mr. Edgar Granda Aguilar the company Professional Geologist who was born and raised in Zaruma for 35 years and educated in Machala and France.

Edgar is communicating with several APROPLASMIN Members in Zaruma including APROPLASMIN’S President elect discussing the acquisition or Joint Venture with a Member to convert their Hg cyanidation Chilean processing center housing 3 tailings ponds to prototype the world’s 1st Hg-free ore processing plant based tailings remediation minerals reclamation pilot plant.

Edgar is well respected and known to all Members owning Chilean processing centers situated on the Calera riverbank.

The Members he approached all have expressed strong interest to participate.

Dr. Marcello Veiga, a globally respected Scientist and pre-eminent scholar is our company Advisor and developer of the Innovative cassava plant Au extraction lixiviant who has built a processing center in Costa Rica producing Au processed with cassava plant extract.

We are preparing to launch our AlchemyLGCoin© #ClimateAction Initial DEX Utility Token Offering (IDO) to raise Impact Investment Capital to implement the TRAP.

We are preparing our Innovation submission for the UPLINK Trillion Trees: Amazon Bioeconomy Challenge which calls for innovative bioeconomy projects in the Amazon Forest that protect and restore biodiversity and ecosystem functions.

We have structured a plan to buy ores or tailings from artisanal gold miners in the Zaruma-Portovelo-Ponce Enriquez areas. We have the resources to accomplish this.

We have developed a corporate site and numerous social media sites promoting our programme to profit proudly from sustainably reclaimed tailings Au, a globally wasted commodity.

How long will the conversion take?

We have scheduled 3 * 2 Q’s equating to 18 months to complete operations to full production including the remediation of the grounds, facility and equipment, removal of the Chilean mills sluices, installation of the requisite equipment, training, the completion of a training/teaching center, and the construction of a resting facility for the miners.

With our plan to purchase ore and tailings, these must be assayed by two certified assay centers one of which we will construct. There are 3 assay centers in the El Pache processing area nearby. The miner will have a 3rd sample for his testing.   

While the testing is being undertaken, the miners will enjoy bread, biscuits, beer all derived from the cassava plant in the plants resting room while we will be televising videos vis-vis Hg toxicity and promoting sustainable Au processing.

How are you financing the project?

To finance the implementation of the TRAP to prototype the world’s 1st Hg-free ore and tailings processing center using a plant-based extract as a lixiviant to recover Au, we are preparing to launch our AlchemyLGCoin© #ClimateAction Initial DEX Utility Token Offering (IDO).
