The San Albino deposit is an orogenic gold occurrence hosted by a low-angle thrust that is the site of a new open-pit mine in northern Nicaragua. Quartz vein-hosted gold was discovered in 1790 in the San Albino area by the Spaniards. Mining, mainly from 1885 through 1926, yielded an estimated 18,200 oz of gold with an average grade of 16 g/t. drilling programs defined a measured plus indicated resource of 541,500 metric tonnes (t) for 178,000 oz Au at 10.2 g/t and 304,000 oz Ag at 17.4 g/t, plus an additional inferred resource of 421,600 t for 101,000 oz Au at 7.4 g/t and 170,000 oz Ag at 12.6 g/t.
