Integra Announces Option Agreement With GreenLight Metals for Cerro Colorado Copper Porphyry Target in Arizona

Vancouver, British Columbia – Integra Resources Corp. (“Integra” or the “Company”) (TSXV: ITR; NYSE American: ITRG) is pleased to announce that Millennial Silver Nevada Inc. (“MSN”), a wholly-owned subsidiary of Integra, has entered into an option agreement (the “Agreement”) dated June 11, 2024 with GreenLight Metals USA Corporation, a wholly-owned subsidiary of Green Light Metals Inc. (“GreenLight”), regarding the Cerro Colorado Property (“Cerro Colorado”). Cerro Colorado is located within the Pima Mining District, 70 kilometers (“km”) (~43 miles) southwest of Tucson, Arizona.

MSN currently owns 100% of the membership interests (the “Interests”) in Millennial Arizona LLC (“Millennial Arizona”) which, pursuant to a mining lease and option to purchase agreement, holds the right to acquire Cerro Colorado. As part of the Agreement, MSN has granted GreenLight an exclusive option for a period of 12 months to purchase the Interests in Millennial Arizona. GreenLight is a private company focused on critical minerals exploration in the United States. GreenLight intends to complete a listing on the TSX Venture Exchange (“TSX-V”) in the near future.

Jason Kosec, President, CEO and Director of Integra commented: “We are pleased to enter into this agreement with GreenLight for the Cerro Colorado property. Cerro Colorado was brought into the Integra portfolio through the merger with Millennial Precious Metals Corp. in 2023 and while the property is currently non-core to Integra, our team has always been excited about the geologic potential of the project as it is situated on the prolific Laramide porphyry copper belt in Arizona. Due to the challenging market conditions in recent years, minimal work has been completed on the project, however with the recent strength in the copper market, we believe GreenLight is the right team to partner with to unlock the value of Cerro Colorado. We look forward to working with the team at GreenLight as the company intends to complete a TSX-V listing later this year and advance its critical minerals portfolio in the United States.”

Key Terms of Agreement

Pursuant to the terms of the Agreement, MSN granted to GreenLight an exclusive option to purchase the Interests as set forth in a membership interest purchase agreement for a period of 12 months. In consideration for the grant of the option, GreenLight has agreed to deliver common shares of the company (the “Shares”) valued at no less than C$500,000 to Integra. The Shares will be paid in two tranches: (i) the first tranche of Shares, valued at no less than C$250,000, will be delivered within five days of the execution of the Agreement; and (ii) the second tranche of Shares, valued at no less than C$250,000, will be delivered at the earlier of: 1) the time of a go-public event, or 2) December 31, 2024. In order to exercise the option and acquire the Interests in Millennial Arizona, GreenLight will pay Integra in cash or common shares of GreenLight, an amount equal to the total 2024 Cerro Colorado holding costs (other than exploration expenditures) incurred by Integra under the preexisting option through the closing date.

Cerro Colorado Property Overview

Cerro Colorado is located within a historic silver mining district, 70 km southwest of Tucson, Arizona, along the Laramide porphyry copper belt. The property is located 26 km southwest of the historical Pima Mining District, which contains several active porphyry copper and skarn mining operations. Seven distinct areas of interest comprise the combined 10,097-acre land package, consisting of 229 unpatented claims on lands administered by the U.S Bureau of Land Management and 14 Arizona State Land Department mineral leases situated on State of Arizona Lands. Cerro Colorado hosts numerous historical mining operations that exploited silver-gold-copper bearing veins hosted by Jurassic and early Laramide volcanic rocks. District-scale and local alteration patterns indicate potential for porphyry copper mineralization within intrusive units beneath the volcanic host rocks. Limited historical drilling in intrusive units adjacent to Integra’s areas completed by Phelps Dodge Corporation (now Freeport-McMoRan, Inc.) and Minefinders Corporation Ltd. reported weakly mineralized porphyry copper intrusions. Recent academic work in the area suggests a lack of Cenozoic extension and dismemberment in the district, preserving the silver-gold veins and associated deeper porphyry copper systems upright and intact below older volcanic rocks.

About Green Light Metals

GreenLight’s mission is to expand known mineral resources and make new discoveries on one of North America’s most prolific yet underexplored volcanogenic massive sulfide (“VMS”) greenstone belts - the Penokean Volcanic Belt (the “Belt”) in Wisconsin, USA. The Belt’s deposits are rich in the clean energy metals copper and zinc, as well as gold, that are required to power the imminent green, low carbon economy. The company’s strategy is to capitalize on its first mover advantage to consolidate, secure, and drill dominant land positions. GreenLight is committed to operating in a responsible and sustainable manner that benefits local communities, bolsters national security, and assists in building and securing crucial U.S. supply chains, all while protecting the environment. GreenLight has established an Environment, Sustainability, and Communities Committee and is fully committed to transparency, accountability, environmental stewardship, safety and community engagement. The company’s key assets on the Belt are the Reef gold-copper and Bend copper-gold properties, each of which contains known historical resources with the potential for expansion. In addition, with the closing of the amalgamation with Can-America Minerals Inc. on July 25, 2022, the company controls two additional prospective properties in Wisconsin - Lobo and Lobo East. GreenLight has also secured rights to the high-priority Swede anomaly located on the Southern Greenstone Belt. Outside of Wisconsin, the company controls rights to the Kalium Canyon property, an exciting epithermal gold prospect located in the Walker Lane district of Nevada.
