BacTech update on Sample Collection
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.
