VANCOUVER, BC, March 21, 2022 /PRNewswire/ - Aris Gold Corporation (Aris Gold or the Company) (TSX: ARIS) (OTCQX: ALLXF) announces it has entered into a definitive agreement with MDC Industry Holding Company LLC (Mubadala), a wholly owned subsidiary of the Abu Dhabi based investment company Mubadala Investment Company PJSC, whereby Aris Gold will acquire a 20% joint venture interest in the Soto Norte gold project in Colombia, with the option to acquire a further 30% interest (the Transaction).

The Soto Norte gold project is one of the world's largest feasibility-stage projects with high-grade mineral reserves, low capital intensity, low operating costs, and district-scale potential. Aris Gold has completed a Feasibility Study technical report on the Soto Norte project, which has been privately held since 2011, which provides a complete description of the project.

Aris Gold has also strengthened its financial position by $100 million by upsizing the existing precious metals stream at the Marmato Mine by $65 million and arranging a $35 million convertible debenture.

Aris Gold will use its position as an established member of the Colombian mining industry to ensure Soto Norte is advanced using the highest international standards to create exceptional value for its shareholders and workforce, the Colombian government, and community partners, while implementing sustainable mining practices that protect the environment and the local ecosystem. Aris Gold operates the Marmato gold mine in the Department of Caldas, where a major expansion is under way and a 30-year mine license extension was received in February 2021 by agreement with the Agencia Nacional de Mineria (ANM).

Aris Gold Chair Ian Telfer stated: "Acquiring interests in large-scale deposits with low technical risk is the right move for Aris Gold. This is how successful gold mining companies are built, and I'm pleased to see Aris Gold is delivering on this responsible growth strategy."

Executive Director, Industrials at Mubadala and Chairman of Minesa, Danny Dweik, said: "We are delighted to bring in Aris Gold as our operating partner in Minesa. The Soto Norte project will benefit from their technical capabilities and Colombian experience, and we look forward to working with them and the local communities on bringing this world-class project to fruition."

Aris Gold CEO Neil Woodyer stated: "Aris Gold will build a successful operation using state-of-the-art technology that will provide long-lasting benefits to the local communities and significant social development opportunities for the region. Soto Norte dramatically increases our growth profile with its potential to produce over 450,000 ounces of gold per year. Construction of Soto Norte is expected to follow the expansion of our 100%-owned Marmato gold mine."

Director, Industrials at Mubadala and current CEO of Minesa, Mohamed Mirza, said: "The team at Aris Gold has extensive local market experience and a long track record of successfully executing complex Colombian projects. We believe they are well-positioned to support Minesa in becoming a leading gold mining company in Colombia."

Soto Norte highlights

Large, high-grade underground gold project:

Indicated mineral resources of 48.1 million tonnes at 5.47 grams per tonne (g/t) of gold, 35.8 g/t of silver, and 0.18% Cu containing 8.5 million ounces (Moz) of gold, 55.3 Moz of silver, and 193 million pounds (Mlb) of copper, inclusive of mineral reserves

Inferred mineral resources of 27.3 million tonnes at 4.06 g/t of gold, 25.9 g/t of silver, and 0.18% Cu containing 3.6 Moz of gold, 22.8 Moz of silver, and 107 Mlb of copper

The mineralized vein structures extend to surface and are open at depth and along strike, with high exploration potential to target the deep structures from underground drilling stations

Tier 1 scale and economics: Soto Norte is designed as an underground mine with 2.6 Mtpa processing capacity and an estimated $1.2 billion initial capital cost, including contingency and pre-production costs. The Feasibility Study estimates:

Average production of 450,000 ounces of gold per year

Life of mine average all in sustaining costs of $471 per ounce of gold

14-year mine life, based on Probable mineral reserves of 24.8 million tonnes at 6.22 g/t of gold, 34.4 g/t of silver, and 0.18% copper, containing 5.0 Moz of gold, 27.4 Moz of silver, and 107 Mlb of copper

After-tax project NPV5% is $1.5 billion and IRR is 20.8%, at base case gold price of $1,675 per ounce

After-tax project NPV5% is $2.0 billion and IRR is 24.4%, at gold price of $1,925 per ounce

District-scale potential: The Soto Norte project is hosted within an area of just over 10% of the mining titles held by the joint venture along the mineralized La Baja fault trend that hosts other mineralized deposits. The neighbouring Galway/Calvista concession has a historical resource estimate prepared by SRK Consulting, effective June 11, 2018, of 2.3 million tonnes in the Indicated category at 4.6 g/t of gold and 35 g/t of silver, containing 0.335 Moz of gold and 2.5 Moz of silver.2

New and informed approach to environmental permitting: Since 2015, extensive technical studies and engagement with the local communities were undertaken in preparing an initial Environment and Social Impact Assessment (ESIA). Following detailed technical feedback from the Colombian environmental regulatory authority (ANLA) in 2021, drafting of a new ESIA commenced and will include a robust Quality Assurance and Quality Control process for regulatory compliance. As operator, Aris Gold's team will contribute its knowledge and experience as well as provide a respectful, licensing process with its local stakeholders.

The Soto Norte project has been designed to minimize the surface footprint, incorporate the latest technology, and meet the highest environmental and safety standards. The processing facility will produce separate gold-rich copper and pyrite concentrates without the use of cyanide or mercury at the Soto Norte site. Dried and filtered tailings will be stored in a dry-stack tailings storage facility designed to comply with Colombian and international standards.

Social development opportunities: Soto Norte will be a significant project for the local and regional communities, providing employment and skills training for up to 1,800 construction contractors and up to 940 full time operations personnel, and a strategy to procure goods and services from the regional community.

Sets Aris Gold on a path to produce 400,000 ounces per year: Together with the Marmato mine, which is expected to produce 175,000 ounces of gold per year when both the Upper Mine and Lower Mine are operating, the transaction will position Aris Gold as a significant mid-tier gold producer in Colombia with aggregate attributable production exceeding 400,000 ounces of gold per year at all-in sustaining costs per ounce sold3 of approximately $650 and generating significant cash flows.
Soto Norte Joint Venture Transaction

On closing Aris Gold and Mubadala will enter into a comprehensive joint venture agreement to govern the joint venture company through which environmental licensing, project development and construction, and mine operation of Soto Norte will be undertaken. Aris Gold will be the project operator, and the joint venture partners will share project costs on a pro-rata ownership basis. Other highlights include:

Cash payments of $100 million from Aris Gold to Mubadala for a 20% interest in the joint venture company and Minesa, with closing of the Transaction expected to occur in April 2022 following satisfaction of customary closing conditions. The cash payments are structured in two tranches with $50 million at closing and $50 million within 12 months of closing.

Aris Gold has the option to acquire an additional 30% interest in the joint venture company and Minesa for a cash payment of $300 million (the Option). Aris Gold may exercise the Option at any time prior to the earlier of a) 10 weeks following receipt of the ESIA approval from ANLA for development of the Soto Norte Project or b) 42 months after closing (Option Expiry Date). The drafting, submission, and approval process for a new ESIA is expected to take approximately two years.

In the event Aris Gold does not exercise the Option prior to the Option Expiry Date, Mubadala may repurchase Aris Gold's 20% interest in the joint venture company at a price equal to the aggregate amount invested by Aris Gold up to that point (i.e., the initial cash payments and paid cash calls).

Following the start of commercial operations, the joint venture partners intend to invest in long-term strategic exploration programs designed to expand the current mineral resources, upgrade mineral resource classification to support the conversion to mineral reserves and extend the mine life.

In consideration of the exploration potential at Soto Norte, Mubadala is retaining a precious metals streaming interest on 7.35% of payable gold and 100% of payable silver. The stream will only apply to incremental production after the first 5.7 Moz gold have been produced which is expected to be achieved following depletion of the current mineral reserves and approximately 30% of the current Indicated mineral resource. Following the 5.7 Moz gold production threshold, Aris Gold's ownership in the joint venture may be decreased based on a remaining life of mine valuation formula that assigns a portion of the economic burden of the precious metals streaming to Aris Gold's joint venture interest, rather than Mubadala. Aris Gold has the option to avoid this future potential ownership dilution by paying the stream burden valuation amount to Mubadala.

Aris Gold and Mubadala will advance the Soto Norte project with consideration of the Equator Principles and the IFC's Performance Standards.
Aris Gold Corporate Finance Update

In preparation for entering the Soto Norte joint venture, Aris Gold has amended the existing $110 million precious metals stream at the Marmato mine with Wheaton Precious Metals International (WPMI) to increase the aggregate total funding amount to $175 million, with additional payments to Aris Gold of (i) $15 million upon closing of the Transaction and (ii) $50 million payable during the construction and development of the new Lower Mine.

In exchange for the increased upfront deposits, WPMI has agreed to purchase 10.5% of the gold production and 100% of the silver production from the Marmato Upper and Lower mines until 310,000 ounces of gold and 2.15 million ounces of silver have been delivered, after which the stream drops to 5.25% of the gold production and 50% of the silver production for the life of mine.

Aris Gold has also arranged to issue, through its wholly owned subsidiary Aris Gold Acquisition Corp., a $35 million convertible senior unsecured debenture to GCM Mining Corp. (TSX:GCM) due 18 months from closing of the Transaction (the Debenture). At any time after 12 months from closing, the Debenture is convertible, in whole or in part, into common shares of Aris Gold at a conversion price that will be determined in the context of the market and rules of the TSX following the issuance of this news release. The Debenture will pay interest monthly with an annualized coupon of 7.5%. The issuance of the Debenture is conditional upon closing of the Transaction and is subject to the approval of the TSX. The ability of GCM to fully execute its conversion rights under the Debenture will be subject to disinterested Aris Gold shareholder approval at the next annual meeting of shareholders.

Technical Information

Historical Resource Estimate

The historical resource estimate at Galway/Calvista has not been verified by Aris Gold and was prepared by SRK Consulting, effective June 11, 2018, prior to Aris Gold acquiring an interest in Minesa. While SRK used industry standard and reliable methods to estimate the mineral resources, categorized the estimates in accordance with CIM definition standards, and reported the resources above a NSR cut-off value of $47 per tonne to consider initial underground mining costs, processing costs, and metallurgical recoveries of 92% for gold and silver and 76% for copper, treatment and payability terms, and metal price assumptions of $1,300 per ounce of gold, $18 per ounce of silver, and $5,000 per tonne of copper, the Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources, nor is there a publicly disclosed technical report to support the disclosure of the mineral resources, and therefore Aris Gold is not treating the historical estimate as current mineral resources.
