Trevali Mining Corporation

At Trevali, we are asking ourselves some big questions about what it means to be a global mining company in today’s world.

We know that modern society needs mineral resources and the products that mining helps create.

As times change, society’s expectations of us change too.

Expectations about environmental responsibility.

Around what it means to be a good corporate citizen.

About being a company that is sustainable for the long-term.

And one that benefits its employees, its communities and its shareholders.

At Trevali, we are excited by these evolving expectations. They inspire innovative ideas and create new opportunities for us to enhance how our business operates.

Motivated by the potential that these questions present, we are focused on constant, incremental improvements in our business. Bringing creativity, agility and innovation into the very heart of the company. Operating efficiently and with the highest of safety standards. We are working to make ongoing improvements that contribute to achieving larger long-term goals.

By asking, and answering, these questions, we will create a different kind of mining company, and a new Trevali.

We embark on this journey with the key ingredients for success: strong assets, potential for resource expansion, a great balance sheet, and an engaged team of professionals.

As a reflection of our new vision, we are also launching a new corporate identity.

We are just getting started. Watch this space.

Restigouche Project

Formerly producing zinc-lead-silver mine located approximately 27-km west-southwest of Trevali’s Caribou mine in the Bathurst Mining Camp of New Brunswick. Restigouche was intermittently mined using an open pit mining method by two different past operators, Breakwater Resources and Blue Note Mining, with the material being trucked to and processed at the Caribou mill, in total approximately 756,000 tonnes were mined historically.

(1)Based on a Mine Plan Reopening Report dated March 2009 and prepared by CSI Mining and Engineering, for Blue Note Metals Inc. Historic resource estimate is based on 236 diamond drill holes and past open pit production, using a 7% lead+zinc cut-off grade. Gold was not estimated. These resources should be viewed as historic and neither the Canadian Provincial Securities Commissions nor the US Securities and Exchange Commission recognize the reporting of historic resources, they are considered conceptual in nature. It cannot be assumed that all or any part of historic geological resources will ever be upgraded to a higher category.

Geology and Mineralization

High-grade sulphide mineralization outcrops at surface and dips gently to the north-northwest. The Restigouche sulphide body has a strike length of approximately 120 metres and continues down dip for 460 metres. Thickness varies between 1-to-plus-30 metres, with an average thickness of approximately 20 metres.

Development Plans

A mining method trade-off study and conceptual mine design is in progress by Mining Plus. In parallel to mine design, additional diamond drilling was undertaken in H1-2018 to obtain geotechnical data, samples for metallurgical test work and to produce a NI43-101 compliant resource estimate. Following receipt of Approval to Operate, development of the mine portal will commence along with refurbishment and installation of site infrastructure: generators, maintenance shop, offices and site security, partly utilizing mobile infrastructure from Trevali’s Halfmile mine site. It is anticipated that initial production from Restigouche to supplement feed to the Caribou mill will be in Q1-2019.
