Certarus Enters Agreement with McEwen Mining to Provide a Cleaner Energy Solution for Mine Air Heating

CALGARY, Nov. 24, 2021 - Certarus Ltd. ("Certarus" or the "Corporation") has entered into a long-term agreement with McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) to convert and supply the Fox Complex in Matheson, Ontario with compressed natural gas (CNG) for mine air heating in the underground ventilation system. CNG will be used to replace propane as the primary fuel for heating at both the Froome and Black Fox Mines.

CNG is a high-performance, lower carbon fuel alternative that offers cost savings and emission reduction benefits. In addition to helping to lower the mine's carbon footprint, the flexibility of Certarus' mobile decompression and storage equipment also allows for the CNG fueling system to be removed in the summer months when it is no longer required for mine air heating.

"Certarus specializes in delivering lower carbon fuel options to customers in isolated areas - and it doesn't get more remote than the bottom of an open pit mine. While the site poses a few logistical challenges, we can safely deliver clean CNG to help McEwen maintain operations, reduce emissions, and improve environmental performance at the Fox Complex. This is our first time mobilizing in a pit mine, and it serves as another great example that Certarus can deliver low carbon energy solutions to our customers, anywhere they operate," said Curtis Philippon, President & CEO of Certarus.

"At McEwen Mining, we are constantly looking for new ways to improve the environmental performance of our operations. With Certarus' mobile CNG delivery, we have a better option to heat our mines, without having to install and store permanent fuel tanks. We can lower costs, simplify fuel logistics, and reduce our carbon footprint. That's a big win for our business," said Rory Greyvensteyn, Director of Operations, McEwen Mining Canada.
