disciplined capital allocation, and strategic guidance as Hercules continues to advance the

Leviathan porphyry copper discovery and evaluate long-term growth opportunities.

appointment as Chairman significantly strengthens Hercules’ board at a critical stage in the

capital markets expertise, and disciplined governance. His direct involvement in advancing

large-scale copper projects and securing strategic financing adds meaningful value as we

continue to advance Leviathan and position the Company for long-term growth.”

Mr. Bos added, “I am pleased to join Hercules as Chairman at an important point in the

Company’s development. “Hercules has assembled control over a significant new copper

district in Idaho. Hercules’ discovery has led to the largest North American staking rush in

30 years and has attracted the attention of every major mining company. The clear strategic

vision to develop this newly discovered copper belt into a tier one mining district, at a time

when the United States is actively encouraging new copper mine developments, is

supported by a strong technical team on the ground. I look forward to working closely with

the board and management to support disciplined decision -making, and value creation for

shareholders.”
