His many and complementary attributes as a Canadian resident with both a technical engineering background and career across the banking and resource sectors make him an ideal fit for Coro. He joins Coro at an exciting time as we now start to focus on Marimaca and I look forward to his contributions.

"I would also like to thank Gordon for his contributions to Coro.  He has been a steady support over the last 8 years at Coro and has helped the Company through some transitioning times. He leaves the Company on a much stronger financial footing and with a clear path to value creation with Marimaca.”
