BacTech update on Sample Collection

Corporate Updates

BacTech Ships Concentrate Samples for Assay Ranging

from 20 to 60 Grams Gold per Tonne

Toronto, Canada September 22, 2020

BacTech Environmental Corporation(“BacTech or the

Company”)(OTC:BCCEF,CSE:BAC) today provided the following update on its

Ponce Enriquez, Ecuador project.

As previously reported, a total of 6, 10-kilogram (22 lbs) concentrate samples

were collected from 6 different processing plants around Ponce Enriquez. There

are over 90 different processors in the area producing anywhere from 1 to over

20 tonnes per day of concentrate that contain high gold and arsenic values. The

output is generated by both mine owners as well as small miners who deliver

mineralized material for processing.

The gold grades of the 6 concentrate samples, as stated by the processors, ranged

between 20 (.64 opt)and 60 (~2 opt) grams per tonne with arsenic values above

10% per tonne.

From the 6 collected concentrate samples, 3 arsenical refractory gold samples will

be prepared and subjected to bioleaching and cyanidation testing. Two of the

concentrate samples are Carbon-In-Pulp (“CIP”) residues and the third is a blend

of flotation concentrates that have not been previously contacted with cyanide.

Regrinding and washing of the cyanide residues will be undertaken to remove

traces of cyanates before bioleach testing and to avoid toxicity issues.

Given the presence of high levels of arsenic, the producers in Ponce Enriquez are

subjected to a heavy discount in the prices they receive for their gold. A survey

conducted by the Company would suggest that producers are paid approximately

65% of the gold value in the concentrate. The majority of the discounted high-

grade gold/arsenic concentrates are bought by Asian smelters or roasters and

shipped there for processing. For comparison, processors of oxide material in

Peru pay roughly 90% of the contained gold value.

BacTech’s plan is to build a 50 tpd bioleach plant capable of treating high

gold/arsenic material in Ponce Enriquez. A 50 tpd plant, processing 1.5 ounces of

gold per tonne of feed, would produce approximately 26,000 ounces per year.

The plants are modular and can be expanded without affecting the ongoing

production.
