Eco Atlantic respectfully announces the passing of Colin Kinley

It is with the greatest sadness that we announce the sudden passing of Colin Kinley, a board member and Chief Operating Officer of Eco Atlantic. The Board and Company express their sincere condolences to Karen, Cooper and Claire, and their extended family and friends.

Colin had a distinguished career over more than 45 years in the mining and oil and gas frontier exploration industries. In addition to his co-founding role with Eco, and the wealth of knowledge and experience he has brought to the Company over the years, he has served as a valued director and senior executive of a number of publicly quoted companies, including Coro Mining, Marimaca Copper Corp. and Gunnison Copper, as well as leading his own teams as CEO and President at Kinley Exploration LLC and Jet Mining Pty LLC.

Effective immediately Gil Holzman and Alice Carroll will assume all responsibilities over Eco's operational and technical teams and the company's country managers will report directly to the CEO.

Gil Holzman, President and CEO of Eco Atlantic, commented:

"Colin's broad experience across both the oil & gas and mining sectors, as well as his unique personality and entrepreneurial spirit, made him a special asset to the natural resources industry. Above all and first and foremost, he was a dear friend of mine, who will be sorely missed by the entire Eco Atlantic Group."
