All currencies expressed as United States dollars unless otherwise stated

i-80 Gold Corp. (TSX: IAU) (OTCQX: IAUCF) ("i-80", or the "Company") is very pleased to announce that it has entered into definitive agreements to create a comprehensive Nevada mining complex through an asset exchange agreement to acquire certain processing infrastructure, including an autoclave, and the Lone Tree and Buffalo Mountain gold deposits from Nevada Gold Mines LLC ("NGM") via an asset exchange in consideration for: (i) the Company's 40% ownership in the South Arturo Property which will consolidate 100% ownership of South Arturo in NGM,  providing NGM with flexibility to pursue potential operational synergies with NGM's other Nevada properties; (ii) assignment of i-80's option to acquire the adjacent Rodeo Creek exploration property; (iii) contingent consideration of up to $50 million based on production from the Lone Tree property; and (iv) arrangement of substitute bonding (and release of NGM bonds) in respect of the Lone Tree and Buffalo Mountain reclamation obligations at closing. The Company has also entered into an acquisition agreement to acquire the Ruby Hill Mine from affiliates of Waterton Global Resource Management ("Waterton") . Additionally, i-80 has entered into a private placement commitment with NGM whereby, conditional on the asset exchange transaction being completed[1], NGM will acquire from i-80 up to 9.9% interest in new i-80 treasury common shares for aggregate proceeds not to exceed $50 million and a non-binding term sheet with Orion Mine Finance ("Orion") for up to $240 million in acquisition and development financing. Equinox Gold Corp ("Equinox") has also indicated that it will participate in the equity private placement through the exercise of a portion of its anti-dilute rights.

Highlights of the transactions are as follows:

• i-80 increases overall Inferred gold Mineral Resource more than three and a half times and more than doubles i-80's overall gold Measured + Indicated Mineral Resources ¹
• Ruby Hill deposits host more than 100 million ounces of indicated silver mineral resources and more than 70 million ounces of inferred silver mineral resources ¹
• Secures for i-80, the ability to process all types of gold bearing mineralization at the centrally located Lone Tree processing facility situated on Interstate 80 once the necessary refurbishment of the facility is completed. The Lone Tree facility includes an autoclave, carbon–in-leach (CIL) mill, Floatation Plant, and heap leach facility
• i-80 will produce gold from the Ruby Hill open pit and residual leaching at Lone Tree
• NGM will provide i-80 with interim processing capacity at its autoclave facilities until the earlier of the three-year anniversary of the asset exchange closing and such time that the Lone Tree facility is operational and also at its roaster facilities for a period of 10-years, subject in each case to extension by mutual agreement
• The Company is pursuing financing arrangements that complement the Company's strong cash position ( $70.1 million as at June 30, 2021 ) including:
• Concurrent with the closing of the asset exchange, NGM will subscribe for new i-80 treasury common shares representing up to a 9.9% interest in i-80 through a private placement for proceeds not to exceed $50 million
• The Company has entered into a non-binding term sheet with Orion for up to $140 million of acquisition financing, with an additional $100 million potentially available via an accordion feature, at the election of i-80
• At the closing of the asset exchange, NGM will reimburse i-80 an amount of approximately $7.3 million for certain expenditures previously advanced in relation to the South Arturo Property ²
• Equinox Gold Corp., the Company's largest shareholder, is expected to participate in the private placement financing through the exercise of its anti-dilution rights

i-80 has entered into a definitive exchange agreement (the " Exchange Agreement ") to acquire the Lone Tree and Buffalo Mountain gold deposits from Nevada Gold Mines LLC ("NGM") , including certain processing infrastructure, via an asset exchange in consideration for: (i) the Company's 40% ownership in the South Arturo Property; (ii) assignment of i-80's option to acquire the adjacent Rodeo Creek exploration property; (iii) contingent consideration of up to $50 million based on production from the Lone Tree property; and (iv) arrangement of substitute bonding (and release of NGM bonds) in respect of the Lone Tree and Buffalo Mountain reclamation obligations at closing. The Company has separately entered into a definitive membership interest purchase agreement (the " Ruby Hill Agreement ") to acquire the Ruby Hill Mine, which includes multiple deposits that collectively, have the potential to represent one of Nevada's largest gold, silver and base metal endowments, from affiliates of Waterton Global Resource Management   ("Waterton") . These two transactions are designed to position i-80 Gold as a prominent, stand alone, gold producer in the state of Nevada. Closing of each of the transactions with NGM, Waterton, Orion and the private placement are subject to the satisfaction of a number of conditions precedent detailed further below, including regulatory approvals and, in the case of Orion, completion of due diligence and the negotiation and execution of mutually satisfactory definitive documentation.

"These transformational acquisitions result in a significant increase in the Company's mineral resource base, and position i-80 to become one of the largest gold producers in the State of Nevada with the capacity to process refractory and oxide mineralization", stated Ewan Downie , Chief Executive Officer of i-80 Gold. "Importantly, i-80 gains a strategic advantage becoming one of only three companies in Nevada with infrastructure to process refractory mineral resources once the Lone Tree facility has been retrofitted to suit the Company's deposits. We believe that this will allow i-80 to overcome a crucial barrier to entry that most of our peers face. In the interim, Nevada Gold Mines has agreed to provide processing capacity for i-80 mineral resources from the McCoy Cove, Granite Creek and Ruby Hill mines at its autoclave facilities until the earlier of three years from closing of the asset exchange and the date the Lone Tree facility becomes operational and will also provide i-80 with processing capacity for ore produced from the McCoy Cove mine at its roaster facilities for 10 years, in each case, subject to extension by mutual agreement, allowing i-80 to commence development of its assets on an expedited basis".

The Lone Tree Property is being acquired from NGM, a joint-venture between the world's two largest gold producers, Barrick Gold Corporation and Newmont Corporation . Lone Tree is a strategically located facility on Interstate 80, the primary highway through northern Nevada, and proximal to the northern Nevada railway, midway between i-80's Granite Creek and McCoy-Cove projects (See Figure 1). The transaction with NGM will provide i-80 with important processing infrastructure including an autoclave, CIL mill, and a heap leach facility complete with assay lab and gold refinery, and also includes interim processing arrangements. NGM has further agreed to acquire up to a 9.9% interest in i-80 through a private placement at the Issue Price (as defined below) for proceeds not to exceed $50 million .

The producing Ruby Hill Mine is host to multiple deposits that collectively have the potential to represent one of the largest gold and silver resource endowments in the State of Nevada . Refractory mineralization from Ruby Hill is expected to be trucked to the Lone Tree Complex for processing following its refurbishment.

"The Lone Tree and Ruby Hill acquisitions will provide i-80 with substantial gold and silver resources and an opportunity to build a mid-tier gold producing company entirely within in the State of Nevada ", stated Matthew Gili , President and Chief Operating Officer of i-80 Gold. "Ruby Hill is host to multiple gold, silver, and poly-metallic deposits that remain wide open for expansion and is expected to be a major contributor to our goal of becoming the second largest producer in Nevada ".

Lone Tree Acquisition

Lone Tree represents a strategic acquisition for i-80, providing the Company with important infrastructure that, following successful refurbishment efforts, will allow it to process refractory and oxide mineralization. Currently on care and maintenance, the property hosts existing infrastructure that includes a whole ore autoclave with capacity of 1M tonnes/year, a flotation circuit with capacity of 1.8M tonnes/year, a CIC circuit & leach pad with 6.5M tonnes of remaining capacity, a tailings dam with 1.5M tonnes of remaining constructed capacity and an additional 10M tonnes of permitted capacity, a waste dump, along with several buildings useful for the development of all i-80's projects including a warehouse, maintenance shop, admin building, and assay lab. The property is also host to substantial gold mineral resources ¹ and offers excellent exploration potential. All deposits at Lone Tree (Lone Tree, Second Chanse and Lynn) remain open for expansion.

• Substantial open pit gold resources contained proximal to the Lone Tree open pit ¹
• 410,000 ounces of gold indicated mineral resources within 7.2M tonnes grading 1.77 g/t Au
• 2,764,000 ounces of gold inferred mineral resources within 50.7M tonnes grading 1.69 g/t Au
• Resource expansion potential exists down-plunge of the main Lone Tree deposit and in the unmined Sequoia zone discovery where previous drilling returned multiple wide, high-grade, intercepts (50% estimated true width) including:
• 9.3 g/t Au across 45.7 m , 11.7 g/t Au across 16.8 m and 9.3 g/t Au across 15.2 m
• Buffalo Mountain is a near-term development opportunity, located approximately 10 km southwest of Lone Tree, that has both open pit and underground potential. Previous drilling by NGM has outlined mineralization in two zones, with highlight intercepts (60-80% estimated true width) of:
• 5.6 g/t Au across 15.2 m , 7.9 g/t Au across 10.7 m and 1.4 g/t Au across 35.1 m in Second Chance deposit (open pit)
• 10.3 g/t Au across 9.1 m and 16.8 g/t Au across 6.1 m in the nearby Lynn Zone that warrants additional drilling

The Lone Tree and Buffalo Mountain Properties are being acquired by i-80's wholly owned subsidiaries Goldcorp Dee LLC ("Goldcorp Dee") and Au-Reka Gold LLC ("AuReka") by way of asset exchange pursuant to the Exchange Agreement, in for (i) Goldcorp Dee's 40% ownership in the South Arturo Property, (ii) assignment AuReka's option to acquire the adjacent Rodeo Creek exploration property, (iii) contingent consideration of up to $50 million based on production from the Lone Tree property, and (iv) arrangement of substitute bonding (and release of NGM bonds) in respect of the Lone Tree and Buffalo Mountain reclamation obligations at closing. Conditional on closing of the asset exchange, NGM has also agreed to complete a private placement for up to a 9.9% interest in i-80 for proceeds not to exceed $50 million , described further under "Acquisition Financing" below. At the closing of the asset exchange, NGM will also reimburse i-80 approximately $7.3 million for amounts previously advanced by i-80 for the autonomous truck haulage test work completed at South Arturo and for funds advanced by i-80 that have not been used for reclamation activities.

In the event i-80 restarts the processing of ore at Lone Tree, NGM will be entitled to receive the following contingent payments of up to $50 million subject to the terms and conditions of the contingent consideration agreement:

i-80 considers the Lone Tree infrastructure to be a strategically located processing facility in Nevada , located on Interstate 80 with the Nevada Railway less than two kilometres to the north, and will be the platform from which i-80 intends to grow its business (see Figure 1 below).

The Lone Tree Deposit ¹ is host to a substantial gold resource that includes 410,000 ounces of gold (Indicated) at a grade of 1.77 g/t Au and 2,764,000 ounces (Inferred) at a grade of 1.69 g/t Au and offers substantial resource expansion potential at depth, down plunge (see Figure 2 below), and in the adjacent Sequoia zone (see Figure 3 below).

The Buffalo Mountain   Property is located approximately 10 km to the West of Lone Tree (see Figure 4 below) and is host to multiple gold zones that have returned multiple significant intercepts including 10.3 g/t Au across 9.1 m and 16.8 g/t Au across 6.1 m at the Lynn zone and 5.6 g/t Au across 15.2 m and 7.9 g/t Au across 10.7 m in the Second Chanse zone (60-80% estimated true width). NGM has initiated the permitting of Buffalo Mountain for development and i-80 expects to continue this effort to commence mining Buffalo Mountain and processing material on the heap leach pad at Lone Tree. The Company expects to complete a mineral resource estimate for Buffalo Mountain in the future.

Closing of the transactions contemplated by the Exchange Agreement is subject to the satisfaction of a number of conditions precedent, including clearance under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended (the "HSR Act"), arrangement of substitute sureties (and release of existing NGM bonds) in respect of the Lone Tree and Buffalo Mountain reclamation obligations, and the approval of the Toronto Stock Exchange ("TSX"), among other customary conditions to closing. The NGM equity private placement (described under "Equity Financing" below) is expected to close concurrently with, and subject to, the closing of the transactions under the Exchange Agreement. The transactions contemplated under the Exchange Agreement and the Ruby Hill Agreement are not inter-conditional or conditional on the completion of the Orion financing transaction. The Orion financing is conditional upon, among other things, the completion of the transactions under the Exchange Agreement and the Ruby Hill Agreement.

Ruby Hill Acquisition

Ruby Hill represents one of Nevada's premier mining projects with existing production from the Archimedes open pit, and a large property that is host to multiple gold, gold/silver, and polymetallic gold deposits, making it one of the largest and highest-grade, permitted, gold deposits in Nevada.

• Substantial open pit gold and silver resources ¹ within the Mineral Point Trend
• Indicated Mineral Resource of 203.2 Mt with an average grade of 0.49 g/t Au and 14.9 g/t Ag containing 3.2 million ounces of gold and 97.5 million ounces of silver
• Inferred Mineral Resource of 157.3 Mt with an average grade of 0.37 g/t Au and 14.3 g/t Ag containing 1.9 million ounces of gold and 72.4 million ounces of silver
• High-grade underground gold mineralization at the 426 Zone
• Indicated Mineral Resource of 1.2 Mt with an average grade of 5.2 g/t Au containing 0.2 million ounces of gold
• High-grade underground gold mineralization at the Ruby Deeps Zone that remains open along strike to the north
• Inferred Mineral Resource of 8.2 Mt with an average grade of 6.0 g/t Au containing 1.6 million ounces of gold
• High-grade poly-metallic mineralization has been defined within the Blackjack

i-80 is acquiring a 100% interest in the Ruby Hill mine and property for consideration of up to $150 million , including milestone payments that are subject to an early payment option that could reduce total consideration to $130 million as follows:

Up to 50% of the foregoing Milestone Payments may consist of i-80 shares, provided that the number of i–80 shares then held by Waterton after giving effect to the share issuance shall not exceed 9.99% of then issued and outstanding shares of i-80 calculated on a partially diluted basis. i-80 shall have the right to prepay the Second Milestone Payment by paying to Waterton, on or before 15 months following closing, $10 million provided that up to $7.5 million of such amount may be satisfied, at i-80's option, in common shares of the Company, priced based on the market price of i-80's shares at the time of such prepayment and i-80 shall have the right to prepay the aggregate of the Third and Fourth Milestone Payments by paying to Waterton, on or before 24 months following closing $20 million provided that up to $10 million of such amount may be satisfied, at i-80's option, in common shares of the Company, priced based on the market price of i-80's shares at the time of such prepayment, provided that the number of i-80 shares then held by Waterton after giving effect to the share issuance shall not exceed 9.99% of then issued and outstanding shares of i-80 calculated on a partially diluted basis.

Ruby Hill includes an open pit mine and related infrastructure (mill/heap leach) and is located immediately west of the town of Eureka proximal to Highway 50.

The Ruby Hill Property is host to multiple gold, silver and base metal deposits that collectively comprise one of Nevada's largest mineral endowments that offer substantial upside. Open pit oxide and transitional resources occur in the Mineral Point, Archimedes West and Archimedes East Zones. Underground sulfide Mineral resources occur in the 426, Ruby Deeps and Blackjack Zones (Figure 5)

Multiple gold and polymetallic exploration targets exist on the property and i-80 will begin an aggressive exploration program immediately following closing. The Company will begin permitting for the construction of a decline to access the high-grade Ruby Deeps deposit and the Blackjack Zone with the intent of trucking refractory mineralization for processing at Lone Tree. Completion of the current mine plan at the Ruby Hill pit will continue with processing at the heap leach facility on the property.  Ruby Hill also includes crushing and CIL processing infrastructure (see Figure 6)

Closing of the transactions contemplated by the Ruby Hill Agreement are subject to the satisfaction of a number of conditions precedent, including regulatory approvals, and the approval of the TSX. i-80 expects to close the Orion financing transaction concurrently with the transactions contemplated by the Ruby Hill Agreement.

Acquisition Financing

In connection with the transactions contemplated by the Exchange Agreement, NGM has agreed to subscribe for new common shares from treasury at a price per share equal to C$2.62 (the " Issue Price "), (being the five day volume weighted average trading price of i-80's common shares ending on the trading date prior to this announcement) in an amount equal to the lesser of $50 million and the amount that would result in NGM holding 9.9% of the issued and outstanding common shares of i-80 on a non-diluted basis, but after giving effect to the private placement (including any participation by other subscribers, including Equinox. upon exercise of its pre-emptive rights and any shares issued to Waterton on or prior to the private placement). The private placement with NGM is part of larger non-brokered private placement offering of common shares by i-80, which includes Orion, of up to $90 million at the Issue Price, not including any shares that may be issued to Equinox upon the exercise of their anti-dilute rights.

The Company has also entered into a non-binding term sheet with Orion for a comprehensive $140 million financing package, complementing the Company's existing strong balance sheet. The Orion financing is contemplated to include a mix of equity and convertible securities, warrants as well as secured instruments, and has a target size of $140 million and, at the election of i-80, an accordion feature of up to an additional $100 million . The equity, convertible securities and the warrants will be priced based on the Issue Price subject to TSX approval.

"The financing packages secured and being pursued with Nevada Gold Mines and Orion, combined with interim processing arrangements, are meant to provide i-80 with the ability to immediately begin development of its substantial portfolio of advanced stage deposits located in one of the world's most favourable jurisdictions for mining", stated Matthew Gollat , EVP Business & Corporate Development for i–80. "The financing packages were structured to limit dilution to our shareholders while providing the Company with potential capacity to aggressively grow our business."
