COMPANY OVERVIEW & UPDATE

Any successes or challenges you’d like to share?

The Silvertip team maintained excellent safety and environmental performance.

Number of employees working on your project(s)?

In December 2022 there were approximately 30 employees on site at Silvertip each work rotation.

Where does the majority of your financing come from year to year? What’s the breakdown of who owns your company?

Our financing comes from our parent company, Coeur Mining, Inc., which is headquartered in Chicago and is a public company listed on the New York Stock Exchange. Coeur Silvertip is wholly owned by Coeur Mining, Inc., which in turn (being a public company) is owned by many types of shareholders, including members of the general public and institutional investors.

Tentative plans and hopes for the 2023 season?

Tentative plans for 2023 are to continue advanced underground exploration, and to continue to develop and enhance environmental management systems, and operating procedures and safety and environmental performance. We will continue to meet with the Environmental Technical Working Group, including Tahltan representatives. At these meetings we keep the Tahltan Nation up-to-date and work together on new permits required.

In February 2020, Coeur temporarily suspended mining and processing activities at Silvertip. Since then, we have been focused on three main activities: advanced exploration, environmental stewardship, and evaluating the potential restart and expansion of Silvertip. In 2022, we carried out underground and limited surface exploration programs. We continued to enhance our environmental management systems and operating procedures.

RELATIONSHIP WITH THE TCG & TAHLTAN NATION

During the 2022 season, what involvement did TCG personnel and departments have with your company? If they were not involved, why not?

Tahltan Central Government (TCG) personnel and departments were actively involved with Coeur Silvertip in 2022 in several ways:

• The Tahltan Lands Department participated in Silvertip Environmental Technical Working Group and the Silvertip Monitoring Committee meetings. These groups collaborate on Silvertip environmental and permitting matters;

• We regularly interacted with the Tahltan Employment & Business Department to discuss and share job opportunities;

• We shared procurement requests for proposals with the Tahltan Nation Development Corporation (TNDC) and TCG Director of Employment & Business;

• We shared employment opportunities with TCG’s Director of Employment & Business;

• We provided scholarship funding to the Tahltan Education & Training Department and collaborated to review scholarship applications.

• We donated to support Tahltan Youth attend Prospectors and Developers Association of Canada (PDAC) and Tahltan literacy camps; and

• We kept the Tahltan Joint Implementation Committee updated on Silvertip status.

In 2022, how many Tahltans did you employ? What positions did they hold in your company and what percentage of Tahltans did you employ compared to others?

At the end of 2022 one Coeur Silvertip employee identified as Tahltan (recently promoted to Environmental Technician, from Junior Environmental Technician). The percentage is currently unavailable.

What employment opportunities, now and in the future, are available to Tahltan members?

There are limited employment opportunities at Silvertip while operations are temporarily suspended. We continue to share employment opportunities with TCG’s Director of Employment & Business.

Why should Tahltan members want to work for you?

At Coeur, we pursue a higher standard by striving to uphold our core values:

• Protect – Our people, our place and our planet

• Develop – Quality resource, growth and plans

• Deliver – Impactful results through teamwork

We understand that we are an integral part of the fabric of the communities in which we live and operate. In addition to working for a company with a strong culture of corporate responsibility, the potential future expansion and restart of Silvertip would offer a great chance to build a long-term career with opportunities for internal advancement.

Do you have any outside contractors working for you? If so, who are they? Who were the primary contractors you utilized? Do they offer employment opportunities to Tahltan members?

Our contractors often share employment opportunities with Coeur Silvertip who shares these with TCG’s Director of Employment & Business.

Anything else you would like to share with the Tahltan Nation?

It has been a privilege to work with Tahltan representatives.
