Trevali Reports 2019 Sustainability Performance

VANCOUVER, May 28, 2020 - Trevali Mining Corp. (“Trevali” or the “Company”) (TSX: TV, BVL: TV) announced today that it has issued its 2019 Sustainability Report, covering new performance targets and disclosures.

“Our second annual Sustainability Report marks another great milestone bringing us one step closer to fulfilling our purpose to become the world’s most sustainable underground mining company,” said Ricus Grimbeek, President and CEO. “We were able to make significant progress in sustainability in 2019, while simultaneously achieving record metal production. We will continue to develop and adopt innovative practices, utilizing technology, which achieves net-positive outcomes for society and the natural environment, while delivering value to our shareholders.”

Trevali believes that metals critical for the world’s transition to a low carbon world need to be mined responsibly. Zinc, lead, and silver are used in low carbon technologies, which enable the transition to electric vehicles and renewable energy. The Company mines these metals in a socially and environmentally responsible way, which mitigates risks and therefore protects the value of the business for shareholders over the long-term.

“In 2019, the HSEC Committee and the management team worked to revise the Company’s Standards for Community, Environment, Safety, Health, Security, Dams and Risk, to align them with the “Towards Sustainable Mining” Protocols set by the Mining Association of Canada. The timely adoption of these Standards and practices have helped the company to ensure that its workforce and local communities are able to sustainably manage the ongoing risks posed by COVID-19,” said Richard Williams, Chair of Trevali’s Health, Safety, Environment and Community Committee.

2019 SUSTAINABILITY PERFORMANCE INCLUDED:
