Manipueira Gold Recovery Technology, Inc.
(f.k.a.) Alchemy Mining Group, Inc. 

An innovation provider with a plant-based technology designed to replace mercury and recover more gold from ore sustainably using manipueira as a lixiviant.

Partner: The United Nations Environment Programme (UNEP) Global Mercury Partnership in Artisanal and small-scale gold mining (ASGM) and mercury waste management sectors.

Member: International Commission on Occupational Health (ICOH); a Scientific Committee on Mining Occupational Safety and Health (MinOSH).

Artisanal and small-scale gold (ASG) miner's ore processing is the Planet’s largest anthropogenic source of deadly mercury pollution documented in 2021 by the University of Oxford earth scientist to stay airborne up to one year.


We propose to prototype a 80 tonnes per day (t.p.d.) mercury free ore and tailings leaching center 1,200 meters high up in the Amazon Andes in the Portovelo-Zaruma mining district Ecuador.


"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.” Dr. Marcello M. Veiga, P. Eng., Professor Emeritus.

According to Adriana Gonçalves et al 2015 publication, there are 240 (two hundred-forty) gold mines and 87 (eighty-seven) whole-ore mercury amalgamation Chilean processing centers operating in the Portovelo-Zaruma mining district Ecuador today.


Sixty-five APROPLASMIN* Members ("Members") process ore and tailings and/or rent their facilities/equipment to the ~10,000 local ASG miners and the ~40,000 neighboring miners all largely having undiagnosed mercury poisoning who transport their ore and tailings for processing. 

These processing centers are lined up along one-square mile on the Calera and Amarillo riverbanks.


Collectively they are responsible for the annual discharge of 1.9 million tonnes of deadly toxic tailings surface sludge waste directly into the Calera and Amarillo rivers polluting Peru’s Puyango-Tumbes river basin.


This deadly toxic pollutant is fluvially dispersed zigzagging throughout the Amazon polluting the rivers and shores while providing mobility for mercury and facilitating the anaerobic production of the deadliest neurotoxin Methylmercury, and with unknown biomagnification effects all to empty into the Pacific Ocean.

A survey** accomplished by the Swedish Environmental System estimated discharges of mercury 40 Kg per year in the River Siete and 160 Kg per year in the River Calera.  

We propose to convert one of APROPLASMIN Members sixty-five whole ore mercury-amalgamation Chilean processing centers  using a plant-based extract to sustainably leach gold from ore and unmanageable toxic tailings ponds for profit.


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

The project is a win - win for the community, environmentalists, cassava plant processors, and our  climate action utility token holders.


Support our Call for Action for impact investment capital to eliminate 1 of the 87 Chilean processing centers monthly use of 2 tonnes of cyanide and 2.4 kg of mercury thereby mitigating further human health threats and biodiversity destruction from that center, one center at a time.


We are allocating 3% of Net Proceeds from operations to develop a mercury detoxification program and facility for all the Portovelo-Zaruma mining district residents.

"Tumbes River basin in mortal danger from consuming water contaminated with metals and toxic minerals.


The presence of metals in the water of the Tumbes River can cause brain diseases, carcinogens and other diseases in the circulatory and reproductive system.


Contamination is from tailings from mining companies in Ecuador."
