Project Overview

Aranzazu is an underground copper-gold-silver mine located in Zacatecas, Mexico, owned and operated by Aura Minerals Inc. The mine was restarted in 2018 as a 3,350 tpd operation and produced 97,558 gold-equivalent ounces in 2024. For 2026, Aura has provided guidance of 68,000 to 76,000 gold-equivalent ounces. In 2024, Aura completed construction of the molybdenum processing plant at Aranzazu, which is expected to add an additional 3,000 to 3,500 gold-equivalent ounces annually. Aura expects to complete a plant upgrade at Aranzazu to increase throughput from 1.27 Mtpa to 1.35 Mtpa in 2026.

An updated NI 43-101 technical report for Aranzazu released in 2025 confirmed a 10 year mine life and projected average annual production of 28.1 Mlbs of copper, 25.2 koz of gold and 652 koz of silver. Exploration remains active across the property, with Aura highlighting ongoing drilling in the deep Glory Hole and continued work on district targets to support mine life extension.

In 2025, Metalla received 678 Royalty GEOs from Aranzazu.
