Challenger Exploration Limited announced that Mr. Sergio Rotondo, current CEL COO, will join the Board of the Company. Importantly, Sergio is also the founder of Golden Mining SA, which originally consolidated 100% of the Hualilan Gold Project, and will now become CEL's 100% owned operating subsidiary as part of CEL's move to acquire 100% of the Project. Sergio will continue to bring his broad business experience including government relations, logistics, and OHS, which he has done at the Hualilan and El Guayabo Projects since the Company was listed.
