"I am delighted to have been appointed Chief Executive Officer of Gem Resources and would like to thank the Board for the confidence it has placed in me.
Having worked extensively in South America since 2014, I have developed a strong understanding of the region's geology, mining industry, regulatory environments and the practical challenges of developing and operating mining projects.
I look forward to working closely with Louis, Bernard and the wider team as we progress GEMR's strategy, particularly the proposed acquisition of the El Yarumo gold processing operation in Colombia, which remains subject to conditions, and the identification of further opportunities across the natural resources sector.
My focus will be on applying sound technical judgement, operational experience and commercial discipline to build a sustainable, revenue-generating business and deliver long-term value for our shareholders."
