(CSE:IMCX), (OTC:IMIMF), (FRA:3MX) ("Interra" or the "Company") is pleased to announce that, further to its press release dated December 2, 2022, the Company has entered into a definitive business combination agreement dated March 8, 2023 (the "Definitive Agreement") with Alto Verde Copper Inc. ("Alto Verde") and 1000465623 Ontario Inc. ("Interra Subco"), a wholly-owned subsidiary of the Company, pursuant to which the Company will acquire all of the issued and outstanding shares in the capital of Alto Verde (the "Transaction").

We look forward to completing the transaction in the coming weeks."

About Alto Verde

Alto Verde Copper Inc. is a private mining company focused on its portfolio of highly prospective exploration assets located in the Central Volcanic Zone, within the prolific Chilean Copper belt.

Alto Verde's portfolio includes three copper exploration projects: Tres Marias and Zenaida in Antofagasta Region, and Pitbull in Tarapaca Region. The Company now holds a significant land package covering an area of 19,850 hectares with the projects situated amongst several of the world's largest mines owned by the largest global mining companies including Glencore, Anglo American, Teck Resources and BHP, among others.

Alto Verde's leadership team is comprised of senior mining industry executives who have a wealth of technical and capital markets experience and a strong track record of discovering, financing, developing, and operating mining projects on a global scale. Alto Verde is committed to sustainable and responsible business activities in line with industry best practices, supportive of all stakeholders, including the local communities in which it operates.

Tres Marías, Pitbull and Zenaida

All three of the Alto Verde copper projects are located in northern Chile within the Central Volcanic Zone (CVZ), home to a majority of the country's production of copper, with much coming from porphyry-style deposits that are rich in copper, molybdenum, gold and silver by-products. Notable copper miners in the region include Antofagasta Minerals, BHP Billiton, Glencore and Freeport-McMoRan Inc. ("FCX") among others. With its well-developed sector, Chile is also known as a highly favourable mining jurisdiction within South America, with a long history of strong mining laws support for foreign direct investment.

Tres Marías is a prospective mid-stage exploration group of concessions covering an area of 16,050 ha and is located within the Paleocene-Lower Eocene Central Metallogenic Belt at a 1,600 m elevation with year-round access in the Region of Antofagasta (the "Property"). There is visible hydrothermal alteration in the outcrops that, based on geological mapping, corresponds to continental clastic sedimentary rocks of the Jurassic Quehuita Formation. FCX completed 2,800 m of drilling in 2015 and 2018, performed in the eastern portion of the Property, including 6 diamond drill holes (DDH) and 1,000 m in 2 reverse circulation (RC) holes, and there remains much to be followed up on. Highlights from these historical drill holes include TMD-15-02 with 2.4 m of 3.10% Cu and 19 ppm Ag, and TMRC-18-01 with 4.0 m of 4.50% Cu and 121.5 ppm Ag. Drilling also indicated anomalous polymetallic zinc, silver, and lead. The central and western-most part of the Property have not been fully assessed despite hosting second priority geophysical targets, suggesting good potential for copper porphyry discovery. Reprocessing and 3D inversion of historical ZTEM airborne geophysical survey, recent completion of a UAV (Drone) MAG survey, and surface IP survey has highlighted three notable targets across the Property. The data from these studies has formed the basis for the upcoming drilling campaign.

Pitbull is an early-stage exploration group of concessions comprising 2,000 ha and located about 25 km north of Anglo American & Glencore's Collahuasi mine ("Pitbull"), which in 2019 produced more than 565 kt of fine copper with revenues of US$ 3.1 Billion. The group of concessions lies within the Upper Eocene-Lower Oligocene (Mid-Tertiary) Metallogenic Belt, a similar geological zone to that of Collahuasi. Initial plans at the property include a high resolution UAV magnetometry survey over 14 km2, an Induced Polarization and Resistivity GSDAS (3D) over 32 linear km, a photogrammetric Survey, and MagnetoVariotional (MVT) Aquisition and 3D Resistivity Inversion study. Data from these studies will determine the drill hole collar locations for a follow-on drilling campaign.

Zenaida is an early-stage exploration group of concessions comprising 1,800 ha, and is also located on the Upper Eocene-Lower Oligocene (Mid-Tertiary) Metallogenic Belt, sharing some similarities to the geology in the Collahuasi region ("Zenaida"). Historical geophysical results indicate the potential for mineralization and warrant further analysis and follow-up by the Company.

As at December 31, 2021, Alto Verde had $377,139 in cash and no liabilities on an audited basis. As Alto Verde is mineral exploration stage, there are no significant sources of revenue or profits.

Transaction Structure

In accordance with the terms of the Definitive Agreement, the Transaction will be effected by way of a "three-cornered" amalgamation, in which: (a) Interra Subco will amalgamate with Alto Verde to form an amalgamated company ("Amalco"); (b) all issued and outstanding common shares of Alto Verde will be exchanged for the Company's common shares ("Common Shares") on a 1:0.2512 basis; (c) all outstanding convertible securities to purchase Alto Verde common shares will be exchanged, on a 1:0.2512 basis, for equivalent securities; and (d) Amalco will become a wholly-owned subsidiary of the Company.
