BUNKER HILL ANNOUNCES APPOINTMENT OF MARK CHILD TO BOARD OF DIRECTORS

Bunker Hill Mining Corp. has appointed Mark Child as an independent non-executive director to the company's board of directors, effective May 6, 2026.

"I am delighted to welcome Mark Child to the Bunker Hill board and as a member of its corporate governance and nomination, audit, and compensation committees," said Richard Williams, executive chairman. "His diverse capital markets and mining experience, plus his proven ability to create shareholder value in complex circumstances, will add much to our team and our governance system as we transition the Bunker Hill critical metals project from commissioning into sustainable, profitable operations."

Mr. Child added: "Bunker Hill represents a unique opportunity to participate in a historic U.S. mining operation, which is expected to restart production next month with a 1,800 tpd processing plant producing critical minerals. The medium-term objective is to target production comprising approximately 50 per cent silver and 50 per cent zinc and lead, supported by a large and significantly underexplored land package. I look forward to working with the board and management team to support the company's next phase of growth as the company expands to a 2,500 tpd processing plant and reviews other growth opportunities."

Mr. Child brings more than 25 years of board-level and executive leadership experience across Alternative Investment Market-, Toronto Stock Exchange- and HKSE-listed mining companies, with a record of advancing mining projects from exploration through feasibility studies, land acquisition, development, permitting and value realization. His expertise spans equity capital markets, corporate finance, corporate governance and international transactions, supported by a global network built over more than three decades in financial markets and the mining sector.

Mr. Child is best known for his leadership at Condor Gold PLC, where he served as chairman from 2006, and later as chairman and chief executive officer. During his tenure, he led the development of the La India gold project in Nicaragua from initial exploration through feasibility and permitting, growing the project to a 2.4-million-ounce gold mineral resource and reserve. He also led the successful sale of Condor Gold to Metals Exploration PLC in 2025 for total consideration of up to $120-million (U.S.), delivering a significant premium to shareholders.

Over the course of his career, Mr. Child has raised more than 50 million pounds sterling in equity financing, secured a strategic investment from the International Finance Corp., and managed complex stakeholder relationships across jurisdictions. His prior experience includes senior roles in corporate finance and institutional equity markets, including executive director and head of corporate finance at Regent Pacific Group Ltd., as well as advisory roles through his own firm, Axial Associates Ltd.

Mr. Child began his career as a commissioned officer in the 2nd King Edward's Own Gurkha Rifles and is a graduate of the Royal Military Academy, Sandhurst. He holds a diploma in company strategy from the Institute of Directors and has completed stock exchange and fund management examinations.
