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.

Quarterly Variability

Zinc: While production guidance has been provided on an annual basis, we expect moderate production fluctuations on a quarter-to-quarter basis due to mine scheduling. Zinc production overall is forecast to be slightly stronger in the second half of 2019, with Caribou in particular expected to deliver a weaker quarter in Q1 as the Company completes the advanced rates of development and production catches up in Q2 – Q4. Conversely, Rosh Pinah is forecast to have a stronger start to 2019, with production strongest in Q1 and declining thereafter as zinc grades decline from approximately 10% to 8%. Due to the mining sequence, lower grades are planned at Perkoa in Q2 and Q3.

Lead: Production is expected to show more quarterly variability than zinc, with consolidated lead production increasing in each successive quarter throughout 2019. Lead grades at Santander and Rosh Pinah are forecast to increase throughout the year, with Rosh Pinah expected to mine significantly higher lead grades in the second half of 2019.

Operating costs: The Company expects costs to generally be at their highest level for each mine in Q1 with consolidated costs per tonne to range from $73 - $81 per tonne during the quarter. Operating costs will be higher in Q1 compared to the yearly target due to the following:

  • Increased mining scope to build inventories and further de-risk annual production;
  • Seasonal impact of winter at Caribou Mine and reduced mined ore until planned development is in place;
  • Benefit of the HFO generating plant at Perkoa is forecast to improve costs starting in Q2;
  • Seasonal pumping requirements at Santander Mine;
  • Lower planned throughput due to planned maintenance.
