TSX-V: ALR explores for copper and gold in Nicaragua, focusing on its Rosita project which hosts the past-producing Santa Rita and R-13 copper mines. Highlights of the Rosita project include a large land package with existing infrastructure, numerous high-priority targets identified through soil and geophysical surveys, and plans for an aggressive exploration program in 2012 including trenching, drilling, and metallurgical studies. The company aims to outline initial resources from mine dumps and advance exploration of porphyry and skarn targets to add value from this underexplored historic mining district.

mining costs and other factors that are set out in the scoping study. Production estimates are based on mine plans and production schedules,
which have been developed by the Company’s personnel and independent consultants. Forward-looking statements are subject to known and
unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of the Company to
