Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. The complaint charges Gold Resource and certain of its officers and directors with violations of the Securities Exchange Act of 1934. The Company, based in Colorado Springs, Colorado, mines, mills and produces metal concentrates that contain gold, silver, copper, lead and zinc at its El Aguila mining project in the southern state of Oaxaca, Mexico. The complaint alleges that, during the Class Period, defendants issued materially false and misleading statements regarding the Company’s operational status and financial projections. Specifically, defendants misrepresented and/or failed to disclose the following adverse facts: (a) that overly aggressive expansion of Gold Resource’s underground mining operations in the first quarter of 2012 had created operational difficulties in the mine, which were lowering mine production; (b) that Gold Resource was mining in lower grade zones of the deposit; (c) that significant operational efficiency improvements were required at the mine, including the need to upgrade electric power throughout the mine, expand ventilation and handle increased ground water the deeper the mine went, which limited the Company’s ability to mine higher grade stopes; (d) that decreases in long-hole stoping were forcing the Company to process more diluted development ore and mine from areas of the deposit with lower metal grades; (e) that as a result of the foregoing, tonnes from stoping, as a percentage of milled ore, had decreased from an estimated year-to-date high of 55% during the first quarter of 2012 to an estimated year-to-date low of 15% during the second quarter of 2012; and (f) that during the third quarter of 2012, a dispute had arisen between the Company and the buyer of its metal concentrates, with the buyer claiming net adjustments (reductions) to the Company’s provisional third quarter 2012 invoices.
