## Exhibit 99.1

**EXHIBIT 99.1**

**Ero Copper Achieves Commercial Production at the Tucumã Operation**

VANCOUVER, British Columbia, July 03, 2025 (GLOBE NEWSWIRE) -- **Ero Copper Corp. (TSX: ERO, NYSE: ERO)** ("Ero" or the "Company") is pleased to announce that the Tucumã Operation, located in Pará State, Brazil, achieved commercial production, effective July 1, 2025. During the month of June, following the completion of commissioning of the third filter press as well as modifications to the process plant, the operation achieved sustained throughput levels exceeding 75% of design capacity.

*"The achievement of commercial production at Tucumã reflects the resilience of our organization over the past several months,"* said Makko DeFilippo, President and Chief Executive Officer. *"We have worked diligently to improve performance at Tucumã, completing necessary repairs and modifications to the process plant to achieve and maintain performance targets. As we move through the balance of 2025, we are focused on delivering safe, consistent production growth, generating strong free cash flows, and investing in the future growth potential we see in the Furnas Project."*

Copper production at Tucumã totaled approximately 6,400 tonnes during the second quarter, including approximately 2,000 tonnes of copper produced during the second half of June. Metallurgical recovery rates and copper concentrate grades have continued to meet or exceed design targets. The Company expects plant throughput volumes to continue increasing through year-end, supporting sequential growth in copper production during the second half of the year.

In connection with the forward-looking statements contained in this press release and in the AIF, the Company has made certain assumptions about, among other things: favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production, development and exploration of the Company's properties and assets; future prices of copper, gold and other metal prices; the timing and results of exploration and drilling programs; the accuracy of any mineral reserve and mineral resource estimates; the geology of the Caraíba Operations, the Xavantina Operations, the Tucumã Operation and the Furnas Copper-Gold Project being as described in the respective technical report for each property; production costs; the accuracy of budgeted exploration, development and construction costs and expenditures; the price of other commodities such as fuel; future currency exchange rates, interest rates and tariff rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and effective manner; work force continuing to remain healthy in the face of prevailing epidemics, pandemics or other health risks, political and regulatory stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for existing approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and capital goods markets; availability of equipment; positive relations with local groups and the Company's ability to meet its obligations under its agreements with such groups; and satisfying the terms and conditions of the Company's current loan arrangements. Although the Company believes that the assumptions inherent in forward-looking statements are reasonable as of the date of this press release, these assumptions are subject to significant business, social, economic, political, regulatory, competitive and other risks and uncertainties, contingencies and other factors that could cause actual actions, events, conditions, results, performance or achievements to be materially different from those projected in the forward-looking statements. The Company cautions that the foregoing list of assumptions is not exhaustive. Other events or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking statements contained in this press release. There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
