MIRARCO Secures Grant Money to Complete Pilot Testing BacTech

Environmental Bioleaching IP for Nickel-Cobalt Recovery from Tailings

TORONTO, ON, August 14, 2023 – BacTech Environmental Corporation (CSE: BAC, OTC:

BCCEF, FSE: 0BT1 ) (“BacTech” or the “Company”), a commercially proven environmental

technology company delivering eco -friendly bioleaching and remediation solutions for precious

metal and critical mineral recovery, is pleased to announce industry partner MIRARCO Mining

Innovation will receive $280,000 in grant money through the Mining Innovation

Commercialization Accelerator (MICA) Network, a program focused on developing initiatives for

the commercialization of mining technology to increase productivity and sustainability within the

mining sector.

The funding will be used to help develop and complete pilot testing of BacTech’s novel

bioleaching process relevant to the treatment of pyrrhotite to advance the recovery of Nickel and

Cobalt battery metals. Pyrrhotite is a very volatile sulphide mineral containing nickel and cobalt

values that oxidizes rapidly and produces large amounts of Iron and Sulphur components as by-

products which are typically considered as wastes. Pyrrhotite tailings used in testing will be

provided to MIRARCO by industry partner Vale.

Dr. Nadia Mykytczuk, a leader in biomining technology, member of BacTech’s advisory board

and President and CEO of MIRARCO Mining Innovation, is leading the development and building

of a bioleach pilot plant to be located in Sudbury, Canada. Working closely with BacTech’s

scientific team, the plant is for the testing of various bioleac hing processes like the Company’s

proposed approach for pyrrhotite treatment.

“Focusing on ‘Made in Canada’ scientific solutions for waste mine management makes sense, and

bioleaching is well positioned to complement modern mining practices and help extr act critical

minerals from waste,” said Dr. Nadia Mykytczuk. “Partnerships with industry are important in

accelerating the scale-up and commercialization of these types of technologies and the MICA grant

will help deliver on these goals.”

About BacTech Environmental Corporation

BacTech Environmental Corporation is a company that specializes in environmental technology.

We use a process called bioleaching to recover metals like gold, silver, cobalt, nickel, and copper,

while also safely removing harmful contaminants like arsenic. This process is eco- friendly and

uses naturally occurring bacteria that are safe for both humans and the environment. By using our

proprietary method of bioleaching, we are able to neutralize toxic concentrates and tailings while

also creating profitable opportunities. The company is publicly traded on several stock exchanges,

including the CSE, OTCQB, and Frankfurt Stock Exchange.

About the Tenguel – Ponce Enriquez Bioleaching Project

BacTech is planning to build a new owner-operated bioleaching facility in Tenguel, Ecuador, in a

region where arsenic is associated with sulphide 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 feed of 1.75 ounces of gold per tonne, similar to feeds available to the Company from

local miners, would produce approximately 31,000 ounces per year. Plant designs are modular and

can be expanded without affecting 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. BacTech has signed an agreement with the government to

build a Phase 2 plant that would see the addition of 150-200 tpd of capacity capable of producing

in excess of 100,000 ounces per annum.

Key economic highlights, assuming a base gold price @ $1,600 per ounce:

• Pre-tax NPV (Net Present Value with 5% discount rate) of $60.7M

• Pre-tax IRR (Internal Rate of Return) of 57.9%

• Annual Gold Production of 30, 900 ounces

• Capital Cost of $17.0M

• Bioleach Operating Cost of $212 per tonne

• Pre-tax Earnings Prior to Employee Bonus – $10.9M annually

• Estimated local employee bonus pool – $1.64M

In total, there are over 100 small mines operating in the area. BacTech continues to investigate the

prospects of establishing additional modern bioleaching facil ities 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 and ensure that they meet t he Company’s high expectations not only for

environmental standards, but also for the highest standards in all ESG considerations.
