Reliance on China for key minerals and metals for national security and clean
energy transition spurs governments and private industry to seek domestic
bioleaching alternatives
TORONTO, ON. January 18, 2022 – BacTech Environmental Corporation (CSE: BAC, OTC: BCCEF,
FSE: 0BT1) (“BacTech or the Company”), a commercially proven environmental technology
company delivering effective and eco -friendly biomining and remediation solutions, today
announced its intention to investigate the use of bioleaching as a tool in liberating Rare Earth
Elements (“REEs”).
Interest in the potential use of bioleaching for the metallurgical extraction of REEs has risen in
recent months, with media reports that the US is actively seeking steps to end depende ncy on
imports of key metals and minerals from China. REEs are classified as strategic elements by the
US government, and the Pentagon has issued a Request for Tender to explore bioleaching
opportunities with the goal of establishing a domestic industry and providing REE supply stability.
REEs are deemed essential for everything from US national security and energy transition delivery
plans, to maintaining supply chain continuity for medical and consumer technologies along with
many other everyday products.
“The US government has made it crystal clear that it is very uncomfortable with China controlling
90% of the global supply of REEs,” said BacTech President and CEO Ross Orr. “We are expanding
our own internal investigation of bioleaching potential in this high demand area, with the intent
to deliver adaptive technology and provide cleaner and cheaper alternatives to REE processors.
I am encouraging both public agencies and private entities in the REEs space to connect with
BacTech and provide us with representative concentrate samples to use in our investigation. This
is another example of our interest and ability to test and push the boundaries of using natural
bacteria as an environmentally-friendly catalyst to safely increase metal production.”
Conventional REE processing typically uses harsh chemical environments of concentrated acids
or alkalis at high temperatures to extract REEs from a broad variety of minerals. By comparison,
the use of bioleaching has potential advantages as the complex nature of REE minerals provides
multiple target sites for microbial activity to release metals of value including REE. Bioleaching
also represents a more natural and environmentally acceptable processing alternative to
conventional processing. Conceptual downstream treatment of REE solutions produced by
bioleaching would be similar to existing downstream operations involving separation and
purification of individual elements from the liquor. Bioleaching is therefore being proposed as
replacing only a current step of leach extraction in an REE flowsheet.
Three different groups of organisms have been promoted as possible candidates useful in
extraction of REE. These are classified as aerobic autotrophs (the current suite of microbial mix
used in BacTech’s bioleaching or bio -oxidation for commercial refractory gold treatment);
aerobic heterotrophs and anaerobic autotrophs. To date, aerobic autotrophs have demonstrated
a robust ability to breakdown a wide variety of mineral matrices and their potential application
in extractive metallurgy of complex REE minerals will be explored first. The design and
engineering of agitated aerated reactor systems suitable for application of aerobic autotrophs to
metallurgical flowsheets is well understood and has been proven over many years.
BacTech fully acknowledges that bioleach processing may not be appropriate to all REE projects
due to differences in mineralogy , but believes the momentum and interest to pursue
environmentally responsible processing alternatives warrants further exploration. As a first
objective, BacTech will source materials from REE projects with mineralogy believed to be most
amenable to bioleach processing. Positive results from such work would lead to more detailed
testing of downstream processing solutions in order to demonstrate proof of concept to specific
REE projects.
About the Ponce Enriquez Bioleaching Project
BacTech is planning to build a new owner -operated bioleaching facility near Ponce Enriquez,
Ecuador, in a region where arsenic is associated with gold ore (Arsenopyrite). The Company’s
plan is to build a 50 tpd bioleach plant capable of treating high gold/ arsenic material. A 50 tpd
plant, processing 1.75 ounces of gold per tonne of feed, similar to feeds available to the Company
from local miners, would produce approximately 26,000 ounces per year. Plant designs are
modular and can be expanded without affec ting ongoing production. The total concentrate
market in the Ponce Enriquez area is estimated to be between 200 and 250 tonnes per day,
allowing for increased throughput potential with a larger plant.
In total, there are over 90 small mines operating in the area. BacTech intends to return local
miner compensation back to previous payment levels, prior to a sweeping price reduction
imposed by Chinese buyers due to recent import levies on arsenic/gold concentrates entering
China. BacTech continues to investigate the prospects of establishing additional modern
bioleaching facilities across other areas of Ecuador, Peru, and Colombia. Where possible, the
Company will partner with national and local governments, non -governmental organizations
(NGOs), and others to assist with the funding of these projects.
About BacTech Environmental Corporation
BacTech is a proven environmental technology company, delivering effective and eco -friendly
biomining and remediation solutions to commercial operations to process and recover preferred
metals (gold, silver, cobalt, and copper) smartly and safely remove and transform harmful
contaminants like arsenic into benign EPA-approved products for landfill. Tapping into numerous
environmental and economic advantages of its proprietary method of bioleaching, BacTech uses
naturally occurring bacteria, harmless to both humans and the environment, to neutralize toxic
mining sites with high- pay potential. BacTech is publicly traded on the CSE under the symbol
“BAC”; on the OTC as “BCCEF”; and the Frankfurt Stock Exchange as “OBT1”.
