VANCOUVER, BC, Dec. 6, 2023 /PRNewswire/ - Metalla Royalty & Streaming Ltd. ("Metalla" or the "Company") (TSXV: MTA) (NYSE American: MTA) is pleased to profile its post-merger core assets and provide a three-year corporate strategy and highlights near-term portfolio catalysts.

• An emerging mid-tier royalty and streaming company now with over 100 royalties and streams with several cornerstone assets including Côté-Gosselin and Taca Taca
• Six producing assets with three more scheduled to commence production in 2024
• Key production contributors for 2024/2025 are expected to be Tocantinzinho, Wharf, Aranzazu, La Encantada, Amalgamated Kirkland, and Endeavor
• Projected gold equivalent ounce ("GEO") production of over 30,000 ounces annually by 2030 from high-quality, long-life projects, expected to result in substantial growth in cash flow
• Best in class jurisdictional risk profile with royalties on assets located in established mining regions across North America, South America, and Australia
• Approximately $35 million in total liquidity available

Brett Heath, President, and CEO of Metalla commented, "After a combined 12 years of respective acquisitions of high-quality growth assets at Metalla and Nova Royalty Corp., the combination underpins a portfolio that is expected to produce over 30,000 GEOs annually by 2030. We anticipate near-term free cash flow growth to be driven by Tocantinzinho, Endeavor, and Amalgamated Kirkland for the 2024/2025 period, firmly establishing our business as a mid-tier royalty company."

Mr. Heath continued, "Over the next three years as we benefit from the many upcoming catalysts in our portfolio, we intend to focus on additional strategic transactions and the development of a capital return strategy."

• Pursue additional strategic transactions to complement best-in-class growth portfolio
• Focus on increasing shareholder value, including the development of a capital return strategy
• Reduce debt and maintain a strong balance sheet

On May 27, 2022, the Company announced that it had entered into an equity distribution agreement to establish an At-The-Market equity program (the "ATM Program"), which could be terminated at any time by the Company or the syndicate of agents. On November 30, 2023, the Board of Directors authorized the termination of the ATM Program and no further sales will take place thereunder. From inception to termination, the Company distributed 1,328,079 common shares under the ATM Program at an average price of $5.01 for gross proceeds of $6.6 million, however, there had been no sales during the five months ended November 30, 2023.

Metalla will enter 2024 with royalties on six producing assets and three new mines that are expected to commence production during the year. The portfolio hosts a commodity mix of gold, silver, and copper, creating blended leverage to monetary, strategic, and inflation resilient metals to preserve purchasing power and grow value over the long term. The portfolio is anchored by 10 core assets profiled below, representing over 50% of the consensus NAV of the portfolio.

Côté is located near Sudbury, Ontario and is poised to become Canada's third largest gold mine with IAMGOLD Corp. ("IAMGOLD") (TSX: IMG) announcing an expected annual output of 495Koz and total cash costs of US$693/oz in the first six years of operation.

Construction is ongoing at Côté and was ~92% complete as of September 30, 2023. The project remains on track to commence production in early 2024.

Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accept responsibility for the adequacy or accuracy of this release.

Metalla has included certain performance measures in this press release that do not have any standardized meaning prescribed by International Financial Reporting Standards (IFRS) including attributable gold equivalent ounces (GEOs). The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's performance and ability to generate cash flow.

Attributable GEOs are a non-IFRS financial measure that is composed of gold ounces attributable to the Company, plus an amount calculated by taking the expected revenue by the Company from payable silver ounces, copper pounds, lead pounds and zinc pounds attributable to the Company, less material costs, divided by the price of gold. The Company presents attributable GEOs as it believes that certain investors use this information to evaluate the Company's performance in comparison to other streaming and royalty companies in the precious metals mining industry who present attributable ounces on a similar basis

The presentation of these non-IFRS financial measures is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. Other companies may calculate these non-IFRS financial measures differently.
