Vancouver, British Columbia – April 21, 2026 - TheNewswire – Lighthouse Gold Corp. (CSE: LGHT) (“Lighthouse” or the “Company”) is pleased to announce the appointment of Mr. Reshud        Mc Lennan as Exploration Manager of the Company and the commencement of its Phase I exploration program at the Aurora NW Project (“Aurora NW”) in Guyana.

Mr. Mc Lennan is an experienced Guyanese exploration geologist and a member of the discovery team at Reunion Gold’s Oko West Project, recently acquired by G Mining Ventures, and one of the most significant recent gold discoveries in the region.

He most recently served as Exploration Manager for Greenheart Gold in Guyana, where he led in-country exploration programs, managed budgets, and directed multidisciplinary teams. His experience spans drill program execution, structural interpretation, and advancing projects from early-stage exploration through resource definition.

Will Rascan, Interim CEO, commented, “This is exactly the type of technical leadership we want on the ground. Mr. Mc Lennan brings direct discovery experience in Guyana and will play a key role as we move Aurora NW from concept to drill-ready targets, in addition to working future business development opportunities in the country. Importantly, Reshud is a Guyanese national and fits our corporate philosophy of investing our future with local technical and management professionals.”

Aurora NW – Prime Location, Clear Plan

Aurora NW consists of four (4) prospecting permits totalling approximately 1,942 hectares in the Cuyuni–Mazaruni region of Guyana, within the highly prospective Cuyuni Greenstone Belt. The Property is located just 3 km from the Aurora Gold Mine concessions and 7 km from the Aurora Gold Mine, Guyana’s largest operating gold mine.

The Company cautions that mineralization on adjacent properties is not necessarily indicative of mineralization on Aurora NW.

Phase I Exploration Underway

Lighthouse is now executing a focused, cost-efficient Phase I exploration program designed to rapidly generate drill targets, including:

- Regional data compilation and reinterpretation

- Project-scale prospecting, geological mapping and structural analysis

- More detailed Rock, stream, and if needed, soil geochemistry

- Data interpretation and target definition across priority zones

The goal is to identify mineralized corridors, and drill-ready targets, with follow-up trenching and drilling anticipated later in the season.

Rascan comments, “Our priority is simple: determine whether structural controls and key lithologies from Aurora extend onto our ground and define targets we can drill this season.”

The Company has granted 100,000 stock options pursuant to its long-term incentive plan. The options are exercisable for a period of two (2) years at a price of $0.10 per share, subject to CSE policies.
