VANCOUVER, BC, July 10, 2024 /PRNewswire/ - Metalla Royalty & Streaming Ltd. ("Metalla") (NYSE American: MTA) (TSXV: MTA) is pleased to report that G Mining Ventures Corp. ("G Mining") (TSX: GMIN) has announced by press release¹ the first gold pour at the Tocantinzinho ("TZ") gold project in the State of Pará, Brazil, where Metalla holds a 0.75% Gross Value Royalty ("GVR").

Brett Heath, President & CEO of Metalla commented, "We would like to congratulate the G Mining team for bringing TZ into production on time and on budget less than two years after the formal construction decision. TZ will become Brazil's third-largest primary gold mine with a 10+ year mine life and significant potential to grow the resource base. Once at full production, TZ will be one of our largest revenue contributors, underpinning our portfolio of high-quality growth and cash flowing royalties."

TOCANTINZINHO

Metalla acquired the 0.75% GVR on TZ in March 2021 for $9.0 million in cash from a third party. The royalty property covers the full extent of the TZ deposit with 28,275 hectares of the land package surrounding the deposit, which includes the Castor and Santa Patricia targets.

G Mining stated in their press release¹ that construction of TZ commenced in September 2022, following the completion of a Definitive Feasibility Study ("DFS") dated February 09, 2022 (filed under G Mining's profile on Sedar+, entitled "Feasibility Study – NI 43-101 Technical Report, Tocantinzinho Gold Project"). The DFS contemplates a 10.5-year mine life with an average annual gold production of 175,000 ounces.

G Mining also stated in their press release¹ that since the start of hot commissioning on June 11, 2024, approximately 77 thousand tonnes of ore had been processed through the TZ process plant, with all circuits operating as expected. The first pour yielded approximately 440 ounces of gold, and the TZ project remains on time and budget for commercial production in the second half of 2024.

Technical and Third-Party Information

Metalla has limited, if any, access to the properties on which Metalla holds a royalty, stream or other interest. Metalla is dependent on (i) the operators of the mines or properties and their qualified persons to provide technical or other information to Metalla, or (ii) publicly available information to prepare disclosure pertaining to properties and operations on the mines or properties on which Metalla holds a royalty, stream or other interest, and generally has limited or no ability to independently verify such information. Although Metalla does not have any knowledge that such information may not be accurate, there can be no assurance that such third-party information is complete or accurate. Some information publicly reported by operators may relate to a larger property than the area covered by Metalla's royalty, stream or other interests. Metalla's royalty, stream or other interests can cover less than 100% and sometimes only a portion of the publicly reported mineral reserves, resources and production of a property.

‎"Inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to ‎their ‎economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ‎ever be ‎upgraded to a higher category. Historical results or feasibility models presented herein are not guarantees ‎or expectations of ‎future performance.‎
