Oro Mining plans to begin gold production at its Trinidad Property in Mexico, where Eldorado Gold previously mined. Oro has discovered gold below Eldorado's mining zone using sonic drilling techniques. Assay results from sonic drilling show better grades than previous RC drilling. Oro's president expresses confidence that further drilling will increase the deposit's known resources. The company aims to produce 40,000 to 60,000 ounces of gold annually after completing a preliminary economic assessment in 2012 and starting construction in 2013.
