Aris Mining Corporation (TSX: ARIS, NYSE American: ARMN) has formally ended its long-standing investment dispute with the Republic of Colombia through a groundbreaking Settlement and Termination Agreement. The legal case, registered as ICSID Case No. ARB/18/23, originated in 2018 under Gran Colombia Gold Corp., which later merged with Aris Gold to form Aris Mining in 2022. Rather than continuing the litigation process through the International Centre for Settlement of Investment Disputes, Aris Mining opted to negotiate a non-financial, performance-based settlement with Colombian authorities. The result is a ten-year cooperation pact centered on mining formalization, security enhancement, and environmental compliance.
The agreement marks a historic first for Colombia. It is the only instance of an investor-state arbitration being resolved without financial compensation, signaling a shift toward more constructive mechanisms for dispute resolution in the mining sector. Aris Mining and Colombia’s National Agency for Legal Defense of the State, known as ANDJE, reached this consensus after months of negotiations intended to reinforce the long-term viability of gold production in Marmato and Segovia.
According to Aris Mining Chief Executive Officer Neil Woodyer, the settlement reflects a shared commitment between the Canadian gold miner and the Colombian government to support sustainable development in mining communities, ensure legal enforcement around operations, and align industry practices with formal regulatory standards.
What are the key terms and governance framework embedded in the settlement agreement?
The settlement completely terminates the ICSID arbitration process and nullifies all claims originally filed by Gran Colombia Gold Corp. in 2018. No financial damages will be paid by either party. Instead, the agreement is based on mutual performance obligations that commit Aris Mining and relevant Colombian institutions to specific initiatives that align with national mining policy, environmental enforcement, and territorial security.
Three formal agreements, referred to as the “Pillar Agreements,” underpin this structure. Each of these was jointly developed by Aris Mining and the Colombian government. The first agreement addresses mining formalization and sustainable territorial development in the Marmato area. It involves close coordination with the Ministry of Mines and Energy and the National Mining Agency to integrate informal mining activity into the legal economy.
The second Pillar Agreement focuses on operational security and cooperation with the National Police. Its goal is to protect Aris Mining’s workforce and infrastructure in territories historically affected by illegal mining and security threats. The third agreement is with the Ministry of Defense and reinforces broader institutional support for lawful mining operations across the company’s Colombian portfolio.
To oversee the implementation of these obligations, a Joint Representatives Committee will be established, comprising members from Aris Mining and ANDJE. This body will monitor compliance, address disputes, and facilitate ongoing dialogue over the ten-year term of the agreement. Each party will bear its own costs associated with the arbitration and the administration of the settlement.
How will environmental enforcement and regulatory compliance be handled under the new framework?
In addition to national-level commitments, regional enforcement will be a core focus of the new arrangement. CORPOCALDAS, the regional environmental authority for the department of Caldas, has agreed to enforce mining and environmental regulations at Aris Mining’s Cerro El Burro site, part of the larger Marmato Complex. CORPOCALDAS will actively monitor compliance, issue sanctions when necessary, and retain authority to impose precautionary measures to ensure responsible resource extraction.
The inclusion of environmental oversight within the structure of a post-arbitration settlement is considered notable. It aligns with broader efforts in Colombia to integrate sustainable development goals into mining governance. Analysts familiar with Latin American mining policy say this model could serve as a precedent for other firms facing similar investor-state disputes.
The Attorney General’s Office will also be engaged under the new framework to support ongoing legal and enforcement processes, specifically those that safeguard Aris Mining’s operations and deter illegal activities. This inclusion elevates the agreement beyond the typical boundaries of arbitration settlements and into the realm of proactive governance.
How does the settlement position Aris Mining within Colombia’s evolving gold sector?
With the arbitration overhang now removed, Aris Mining appears well-positioned to scale up production and execute on a broader expansion roadmap across Colombia and Guyana. In 2024, Aris Mining’s operations at the Segovia Operations and Marmato Complex delivered a combined 210,955 ounces of gold. The company has set its sights on surpassing 500,000 ounces of annual production through operational upgrades and new infrastructure.
A major component of this plan is the commissioning of a second mill at Segovia, completed in June 2025 and currently ramping up. At Marmato, the development of the Bulk Mining Zone is expected to bring the first gold output in the second half of 2026. With these assets scaling simultaneously, the company could more than double its production base within two years, assuming smooth construction and regulatory timelines.
In Guyana, Aris Mining controls the Toroparu gold project, which is progressing through a Prefeasibility Study after completion of a new Preliminary Economic Assessment. The Toroparu asset offers significant growth potential, and once the PFS is finalized, the project will be ready for consideration of construction financing and execution.
Aris Mining also holds a 51 percent interest in the Soto Norte joint venture, one of the highest-grade gold projects in Colombia. A Prefeasibility Study has already confirmed the project’s strong economics and environmental design. Final environmental studies are expected to be submitted in the first half of 2026 to initiate the licensing process.
What are investors and institutional analysts saying about the implications of this legal settlement?
Market participants tracking Aris Mining believe the settlement improves the company’s regulatory standing and reduces political risk in Colombia, a country where community tensions and illegal mining have often posed challenges to foreign operators. Analysts say the absence of financial damages under the settlement signals disciplined legal strategy and may enhance Aris Mining’s credibility among stakeholders concerned with environmental, social, and governance (ESG) metrics.
Sentiment among institutional investors appears cautiously optimistic. With the arbitration now closed, analysts expect investor focus to return to near-term production milestones and permitting timelines for the Toroparu and Soto Norte projects. The company’s dual listing on the Toronto Stock Exchange and the NYSE American offers visibility into both North and South American markets.
While the stock price remained stable in immediate trading following the announcement, some analysts note that the removal of legal uncertainty could reduce perceived sovereign risk and improve financing conditions for upcoming project developments. No material financial impact from the arbitration was recorded on Aris Mining’s balance sheet, and future capex plans remain fully funded through internal cash flows and existing credit facilities.
What comes next for Aris Mining as it transitions from legal resolution to growth execution?
Following the execution of the Pillar Agreements, the spotlight will now shift to the governance and performance of the Joint Representatives Committee tasked with oversight. Investors will also be monitoring Aris Mining’s ability to meet its formalization goals in the Marmato area and ensure continued community engagement under the new framework.
On the operational front, key deliverables include the full ramp-up of the Segovia mill during the second half of 2025, initial construction milestones at the Marmato Bulk Mining Zone, and the completion of environmental and feasibility work at both Toroparu and Soto Norte. With gold prices remaining favorable and ESG scrutiny at an all-time high, Aris Mining is under pressure to demonstrate that this legal resolution can translate into durable shareholder value and local impact.
Analysts believe that the model of resolving investor-state disputes through long-term cooperation agreements could gain traction in other Latin American jurisdictions, especially if Aris Mining’s execution within this framework proves successful. For now, the company has turned a contentious chapter into a potentially stabilizing force for its future operations.
