Overview

Aris Mining Corp. is a mid-tier gold producer headquartered in Vancouver, Canada, operating primarily in South America. The company's portfolio consists of 4 projects, comprising 2 operating mines, 1 development, and 1 advanced exploration project. Key assets include Marmato, Segovia, and Soto Norte. The company's business model integrates its own mining activities with a partnership program for small-scale miners, providing them with technical, operational, and safety expertise, as well as working capital financing. This collaborative approach formalizes smaller operations, enabling them to establish formal companies and gain access to legal markets and government benefits. Processing capabilities include the production of doré and the operation of a polymetallic plant that processes tailings to extract additional saleable concentrates, which serves to reduce environmental impact while generating supplementary revenue. The organization is not dependent on a single purchaser for its principal products due to the deep and liquid nature of the global market. A key competitive aspect is the ability to select and acquire suitable producing properties or prospects for development. The business is subject to mineral price cycles, with marketability affected by worldwide economic conditions and macroeconomic factors beyond the entity's control.

Strategy

Strategic focus centers on blending cash flow from current operations with transformational growth driven by expansions, exploration, and development projects. The enterprise intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification. A core objective is the continual addition to its mineral base through a combination of acquisitions, exploration, and development. Capital allocation is prioritized to advance high-return growth opportunities within the company's portfolio. The organization's approach involves managing a portfolio of assets at different stages, from production and construction to permitting and exploration, to create a sustainable growth pipeline. This includes advancing studies for new, smaller-scale development plans for certain projects and optimizing the development strategy for others. The company also aims to increase the production contribution from its contract mining partners by implementing strategies to support their growth.

Management

Executive leadership is headed by CEO Neil Woodyer, an experienced executive with a track record in the mining industry, including roles at Endeavour Mining and Leagold Mining. The Board is led by Chair Ian Telfer, an inductee of both the Canadian Mining Hall of Fame and the Canadian Business Hall of Fame, with previous experience as Chair of Goldcorp Inc. The 8-member Board of Directors includes a technical consultant and oversees corporate strategy through several committees, including Audit, Sustainability, Compensation, and Corporate Governance & Nominating. The 3 members of the Audit Committee are independent and financially literate. Governance practices are structured to manage conflicts of interest, requiring directors and officers to disclose any material conflicts and abstain from voting on related resolutions, in accordance with the Business Corporations Act (British Columbia). In appropriate cases, a special committee of independent directors is established to review matters where conflicts may exist.

Sustainability

The organization's sustainability framework is guided by policies covering environmental and corporate social responsibility, business ethics, anti-corruption, diversity, and human rights. A key environmental initiative involves a polymetallic plant that reprocesses tailings to extract additional metals, reducing environmental impact. The company rehabilitated a former tailings facility into a 9,200 m² public ecopark featuring cultural and sports amenities, serving as a model for sustainable tailings management. In partnership with regional authorities, the enterprise is implementing 'fast-track' initiatives that include constructing a state-of-the-art industrial water treatment plant. Social programs focus on formalizing small-scale miners through contracts that provide access to social security, training, and legal markets. The social investment framework is built on 5 pillars, funding over 90 projects in 2024 related to infrastructure, education, economic development, and healthcare, benefiting thousands of community members.

Structure

A significant structural change occurred in 2022 when the company acquired all outstanding shares of Aris Gold Corporation, which became a wholly-owned subsidiary and resulted in the appointment of the Aris Gold management team and board to the parent company. In 2024, the enterprise increased its ownership interest in the Soto Norte Project to 51% and became the operator under an amended and restated joint venture agreement with its partner, Mubadala. This transaction replaced a previous option agreement and established Mubadala as a significant shareholder, holding approximately 9.16% of the company's common shares, which are subject to a 12-month contractual hold period expiring in June 2025. The company's operations are conducted through several material subsidiaries, including Aris Mining Holdings Corp., AM Segovia, Aris Mining Marmato S.A.S., and ETK, Inc. The company has a right-of-first-offer should its joint venture partner choose to exit the Soto Norte Project.
