November 17, 2025 – TheNewswire - Vancouver, Canada – Radius Gold Inc. (TSXV: RDU) ("Radius" or the "Company") is pleased to announce the appointment of Mr. Alejandro Ly as Vice President, Exploration, bringing more than 25 years of discovery-driven experience across the Americas and a proven discovery record advancing projects from early-stage prospecting to resource development and feasibility.

Mr. Ly is a dual U.S.–Peruvian exploration geologist from a multi-generational mining family and a Certified Professional Geologist (AIPG CPG 11723) with extensive leadership in precious and base-metal systems across the Americas.

Mr. Ly played a central role in the discovery and definition of the 15+ Moz Goldrush deposit in Nevada during his nine-year tenure with Barrick Gold. As Project Geologist for Goldrush, he was a key member of the team that received the 2014 Thayer Lindsley Award for International Mineral Discovery of the Year from the Prospectors & Developers Association of Canada. Mr. Ly also contributed to the resource definition and development of the 30 Moz Donlin Gold deposit in Alaska. He has since held senior project leadership and technical roles with Rio Tinto, MMG, and Nyrstar, managing exploration programs ranging from early-stage target delineation to resource modelling and feasibility.

As Vice President, Exploration, Mr. Ly will lead Radius& technical team, project evaluation, and field operations, with an immediate focus on advancing the Tierra Roja copper project and leveraging his extensive Peruvian, Mexican and U.S. connections to expand Radius& project pipeline.

Bruce Smith, President & CEO of Radius Gold, stated: “Alejandro brings world-class discovery experience and a deep understanding of the geological environments that matter most to Radius. His track record advancing projects from early exploration through development will be invaluable as we advance Tierra Roja and evaluate new opportunities across Peru, Mexico, and the broader Americas.&

Alejandro Ly commented: “Radius Gold holds a compelling portfolio with meaningful upside in both precious and base metals. Having recently visited Tierra Roja to review targets and supervise drill pad construction, I am excited to commence drilling and to apply my experience to identify and advance additional opportunities for the Company. I look forward to working with Radius& technical team to build long-term value through disciplined, discovery-focused exploration.&

Tierra Roja Project – Drilling Program Status

Radius has continued to prepare for drilling at the Tierra Roja copper-gold project, where the Company has completed extensive geological mapping, sampling, and target definition.

The Company has:

• defined initial drill targets

• constructed drill pads

• engaged drilling contractors and field staff

• secured water supply

• received the Environmental Permit (DIA)

The project area is uninhabited and located on federal land, with no community presence or occupants on site.

All required permissions to commence drilling have been obtained except for a final administrative access waiver that applies to federally managed but unoccupied land. The Company notes that this last step has taken considerably longer than anticipated, despite consistent and proactive engagement with the relevant authorities.

Radius is ready to commence drilling immediately upon receipt of this final authorization.

Mr. Smith added: “Our team in Peru has worked continuously to complete the required technical, environmental, and logistical steps. We share the frustration of our stakeholders regarding the delay in receiving the final access authorization. All field infrastructure is complete and the program is drill-ready. We look forward to initiating drilling as soon as this last permit is granted.&
