The Don Mario District

The Don Mario district has three main mineral deposits of which the largest, the Don Mario Lower Mineralized Zone (“LMZ”) low-cost gold mine, was depleted in the fourth quarter of fiscal 2009 after producing more than 420,000 ounces of gold. The second, the Las Tojas open-pit gold mine, was depleted in March 2011 after producing nearly 50,000 ounces of gold. The open-pit mine on the third deposit, the copper-gold-silver Upper Mineralized Zone (“UMZ”), reached commercial production in January 2012 and was depleted in 2016.

Since Don Mario Operation suspended mining in 2019, due to depleted resources and reserves in the deposits, the only current mineral resource estimates on the Don Mario Property are the Don Mario Mine tailings (“Don Mario Tailings”) and oxide stockpiles (“Don Mario Stockpiles”).

The following table sets forth the production from the Don Mario Mine for the periods indicated together with guidance for the upcoming period.
