historic mining districts, is incredibly exciting. I look forward to working with the management
team and Board to support Bunker Hill's continued success."

AWARD OF ‘A’ GRADE IN DIGBEE ESG ASSESSMENT
The results of Bunker Hill’s latest independent ESG assessment of its operations and corporate
governance system , conducted by Digbee Limited (“ Digbee”), a leading technology platform
specializing in ESG disclosure and benchmarking for the mining sector, have been published.
In its fourth Digbee review — and its first conducted under the Operations Phase analysis
framework, Bunker Hill achieved an overall ESG score of “A” (range: “B” to “AAA”) as of April
2026, representing a significant improvement over the Company’s previous assessment.
The assessment reflects the positive way that the Company integrates ESG principles into all
aspects of its operations, governance, and long-term strategy. As with previous Digbee reports,
the advice provided by Digbee assists the Company in advancing and developing this approach
further, helping it to achieve the coveted AAA grade in the future.
A LANDMARK MINE RESTART IN THE UNITED STATES
The historic Bunker Hill Mine, located in Idaho’s prolific Silver Valley is advancing now towards
commercial production. The restart of this mine after 45 years of closure and remediation
represents the first mining operation to restart commercial mining within an active U.S. EPA
Superfund-designated cleanup site since the establishment of the Superfund program in 1969 .
This represents a significant milestone for both the Company, the broader U.S. mining industry,
and the community of the Silver Valley.
RESPONSIBLE REDEVELOPMENT WITH LONG-TERM COMMUNITY BENEFITS
The Bunker Hill Mine redevelopment includes:
• remediation and modernization of historic infrastructure;
• installation of modern processing and environmental systems;
• in-mine water treatment and milling infrastructure;
• filtered tailings technology; and
• placement of tailings underground to reduce long-term surface impacts.
The mine is expected to directly employ between 200 and 250 people once commercial
production is reached , with indirect employment estimated at approximately 1,000 jobs
throughout the region. Most employees and contractors are expected to be drawn from local
communities within Idaho’s Silver Valley and surrounding areas.
POSITIONED TO SUPPLY ESSENTIAL METALS FROM WITHIN THE USA
The Bunker Hill Mine produces silver, zinc, and lead concentrates from Idaho’s prolific Coeur
d’Alene Mining District — a significant historic silver-producing region in the United States and
the supplier of some of its best underground miners.
As the USA prioritizes domestic industrial capacity and secure supply chains, Bunker Hill is
positioned to play its part as an American producer of both precious and industrial metals via
the responsible restart of a historic mining operation.
COMMITMENT TO ESG LEADERSHIP
Digbee’s assessment highlighted the Company’s experienced leadership team, strengthened
governance framework, and continued enhancement of corporate policies and operational
standards.
Bunker Hill remains focused on:
• operational excellence;
• high standards of environmental stewardship;
• workforce safety;
• community engagement; and
• transparent governance practices.
As the Bunker Hill Mine advances now toward commercial production making use of modern
technology, practices and systems , it aims to maintain the highest standards of operational
excellence in all matters, including environmental management. Partnered with the community
of the Silver Valley, and alongside those other local mining companies that are investing in
operations nearby, it seeks to play an important part in offering skilled, well paid and modern
employment in a revitalising domestic United States mining industry: delivering critical metal
into the US supply chain, creating long-life, dynamic United States jobs and in ways that protect
and enhance the environment around it.

economic risks of failure which are associated wi th this production decision including, among
others, areas that are analyzed in more detail in a feasibility study, such as applying economic
analysis to resources and reserves, more detailed metallurgy and a number of specialized
studies in areas such as mining and recovery methods, market analysis, and environmental and
community impacts and, as a result, there may be an increased uncertainty of achieving any
particular level of recovery of minerals or the cost of such recovery, including increased risks
associated with developing a commercially mineable deposit, with no guarantee that production
will begin as anticipated or at all or that anticipated production costs will be achieved; failure to
