Santa Gertrudis

Santa Gertrudis is a past-producing mine located in Northern Sonora, Mexico. Historically, Santa Gertrudis produced over 550 koz of gold in the 1990s at an average head-grade of 2.13 g/t gold. Recent exploration success has led to the discovery of two new high-grade deposits, called Amelia and Espiritu Santo.

Agnico is evaluating a potential heap leach operation for the open pit lower grade ore and a small mill facility to process the higher-grade ore. Agnico believes that Santa Gertrudis has the potential to be a similar size operation to the La India mine.

Metalla holds a 2.0% NSR royalty on the property, subject to a 1.0% buy back for US$7.5 million.
