Corporate Updates

Copperhead Announces Approval of Change of Business

Vancouver, BC, January 20, 2026 –Copperhead Resources Inc. (to be renamed Deep Sea

Minerals Corp. ) (CSE: CUH) (OTCPK: CUHRF) (FSE: X45) (" Deep Sea " or the

"Company") is pleased to announce that, further to its news release of January 19, 2026, that the

Company’s change of business to focus on subsea critical mineral exploration and development (the

“Change of Business”) and name change to “Deep Sea Minerals Corp.” (the “Name Change”) have

been approved by a majority of the Company’s shareholders by written consent. The Company has

also received final approval from the Canadian Securities Exchange (the “CSE”) for the Change of

Business.

Subject to final approval from the Canadian Securities Exchange regarding the Name Change, the

Company expects the Name Change to be effective on or about January 26, 2026, at which time the

common shares in the capital of the Company (the “Shares”) are expected to trade on the Canadian

Securities Exchange under the symbol “SEAS”.

The new CUSIP will be 24378A101 and the new ISIN number will be CA24378A1012, under the

new name of the Company.

In connection with, and in anticipation of, the Name Change, the Company has completed a

corporate rebrand and launched a dedicated website at www.deepseamineralscorp.com, providing

investors and stakeholders with an overview of the Company’s strategic direction, governance

framework, and evolving focus within the deep-sea critical minerals sector.

“This is a foundational milestone for the Company, and we are incredibly excited to launch our new

branding, which will better align our operations with the Company’s long-term strategic directives,”

said James Deckelman, CEO of Deep Sea Minerals Corp. “The approval of our change of business

formally marks our entry into one of the most strategically important frontiers in the global resource

development and critical minerals sector. As governments and industries confront growing supply-

chain constraints for critical minerals essential to defense, energy transition, and advanced

technologies, the deep seabed is increasingly being evaluated as a long-term strategic resource. Our

objective is to position Deep Sea Minerals early, responsibly, and methodically within this emerging

sector.”

POLICY & STRATEGIC CONTEXT

The Company’s strategic focus aligns with recent policy actions by the United States government

emphasizing the importance of securing long- term access to critical minerals. In particular, an

Executive Order issued by President Donald J. Trump directed U.S. federal agencies to accelerate

the assessment and development of deep-sea mineral resources as part of a broader effort to reduce

reliance on foreign -controlled supply chains for materials deemed essential to national defense,

advanced manufacturing, and economic security.

This Executive Order was reinforced in a January 14, 2026 Trump Administration Proclamation

directing the U.S. Commerce Secretary to pursue negotiation of agreements to address the threatened

impairment of the national security with respect to imports of Processed Critical Minerals and

Derivative Products (PCMDPs) from any country.

These actions underscore growing recognition at the highest levels of government that seabed

mineral resources may represent a strategically important component of future critical -minerals

supply. Deep Sea Minerals believes that early, disciplined engagement in this sector —guided by

technical rigor, environmental responsibility, and regulatory coordination—positions the Company

to participate constructively in an emerging area of global resource development.

ABOUT DEEP SEA MINERALS CORP.

Deep Sea Minerals Corp. is a subsea mineral exploration and development company focused on

evaluating opportunities to support the future supply of critical minerals through the acquisition,

exploration, and development of deep-sea mineral assets.

The Company’s strategy is centered on identifying jurisdictions and geological settings with

potential exposure to polymetallic nodule systems, which are recognized for containing

combinations of metals that may be relevant to defense, industrial manufacturing, clean energy

infrastructure, advanced electronics, and artificial intelligence-related supply chains. These seabed

resources represent a largely undeveloped component of the global mineral supply base and are the

subject of increasing policy, scientific, and regulatory attention worldwide.

As part of this process, the Company has commenced early- stage engagement with select

governments and regulatory stakeholders in the Pacific Ocean region to assess potential pathways

for future exploration initiatives, subject to applicable international, national, and environmental

frameworks.
