Aura Minerals Inc. is pleased to announce that the Ernesto open pit mine (“Ernesto mine”), part of the Ernesto/Pau-a-Pique mine complex (“EPP”), located in the southwest of Mato Grosso state, near Pontes e Lacerda in Brazil, has declared commercial production effective October 1, 2020. In October 2020 production achieved 2,507 ounces of gold in the Ernesto mine alone.
Thanks to the contribution from the Ernesto mine, in October 2020 EPP achieved its highest production since the 2016 start-up, with 8,233 of ounces of gold produced.
At Ernesto, the Company expects an increase in production in the fourth quarter of 2020. Following this, the Company plans a push back in the mine in order to access high grade ore by Q4 2021, which the Company then expects to be able to access through to the end of 2022.
Rodrigo Barbosa, the Company’s President and CEO noted, “In January 2019 we started to develop the Ernesto mine (pre-stripping). We are glad to see the higher grades into production for the coming quarter and we look-forward to reaching the ore body again during the second semester of next year. The Ernesto mine is expected to provide approximately 125,000 Oz at 3.0 g/ton average grade during the life of the mine”

Technical Information Relating to the Project
EPP is comprised of multiple operating open pits (Lavrinha, Ernesto and Japones), an open pit mine under development (Nosde), and one underground mine (Pau-Pique) located in the southwest of Mato Grosso state, near Pontes e Lacerda in Brazil.
Aura has filed a technical report dated January 13, 2017, with an effective date of July 31, 2016, and entitled “Feasibility Study and Technical Report on the EPP Project, Mato Grosso, Brazil” prepared for Aura by a group of third-party consultants, including P&E Mining Consultants Inc., MCB Brazil and Knight Piesold Ltd. with respect to EPP (the “Feasibility Study”). The results of the Feasibility Study were announced in a press release in November 2016. Aura resumed commercial production from the Lavrinha open pit and Pau-Pique underground mine in 2017 and Japones open pit mine in 2018.
Pre-stripping development started at Ernesto in early 2019 with waste stripping, which continued into August 2020 to reach the ore body (Lower Tarp), which was delineated at the time of Feasibility Study. Ernesto has contributed to production from EPP since August 2020.
As of December 31, 2019, Ernesto is estimated to have measured and indicated resources of 923,990 tonnes @ 4.58g/t Au containing 136,100 ounces of gold, and inferred resources of 1,215,550 tonnes @ 2.46 g/t containing 96,140 ounces of gold. The total proven and probable reserves is 1,047,300 tonnes @ 3.41 g/t Au containing 114,820 ounces of gold. Mineral resources are inclusive of mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The main part of the inferred resource disclosed herein is not amenable to open pit mining. Readers are encouraged to reference the annual information form of the Company dated March 30, 2020 for the year ended December 31, 2019 filed under the Company’s SEDAR profile at www.sedar.com for further information, including important assumptions and qualifications, with respect to the resource and reserve estimates disclosed herein for Ernesto.
