Newmont and Barrick Optimise Nevada Gold Mines JV to Boost Efficiency and Margins

The Nevada Gold Mines (NGM) joint venture represents one of the most significant consolidations in the modern gold mining industry. Formed in 2019, the JV combines the Nevada assets of Barrick Mining Corporation (NYSE: GOLD, TSX: ABX) and Newmont Corporation (NYSE: NEM, TSX: NGT), creating the world’s largest gold-producing complex.

Barrick operates the JV with a 61.5% ownership stake, while Newmont holds the remaining 38.5% interest. The partnership consolidated multiple Tier 1 assets across northern Nevada into a single, integrated operating platform, enabling significant synergies across mining, processing and infrastructure. Since its formation, the JV has consistently produced between 3.0 and 3.3 million ounces of gold annually, representing roughly 15–20% of total US gold production.

The complex includes major mining districts such as Carlin, Cortez, Turquoise Ridge and Phoenix, supported by a network of processing facilities, including roasters, autoclaves and heap leach operations.

A cornerstone of the NGM portfolio is the Carlin Trend, one of the most prolific gold-producing regions globally.

The Carlin system comprises multiple underground and open pit operations feeding a centralised processing network. Ore types vary significantly, requiring a combination of processing methods including pressure oxidation (autoclaves), roasting and heap leaching. Carlin alone contributes approximately 1.6 to 1.8 million ounces of gold per year.

The scale and complexity of Carlin make it a benchmark for integrated gold mining operations. By consolidating assets under the JV, operators have been able to optimise ore routing, ensuring that material is processed through the most efficient pathway based on its metallurgical characteristics.

Since the formation of the joint venture, a key focus has been on improving operational efficiency through integration and standardisation. This includes aligning maintenance practices, consolidating procurement and optimising workforce deployment across sites.

One of the most significant improvements has been in ore blending and processing efficiency. By leveraging multiple processing facilities, the JV can adjust feedstock to maximise recovery while minimising cost. For example, refractory ores are directed to autoclaves, while oxide ores are processed via heap leach circuits.

Carlin Complex Insight:
At the Carlin complex, optimisation of autoclave throughput and improved ore blending strategies have led to measurable increases in gold recovery rates while reducing processing costs per ounce. This has been supported by enhanced data analytics and process control systems.

In parallel, underground operations have benefited from improved mine planning and scheduling, enabling more consistent ore delivery and reduced variability in plant feed.

Since inception, operational integration has delivered tangible improvements in both production consistency and cost performance.

Key verified outcomes include:

• Sustained annual production above 3 million ounces, despite declining ore grades across several deposits

• Improved gold recovery rates, particularly in refractory ores processed through autoclaves, with recovery efficiencies typically exceeding 90%

• Reduction in all-in sustaining costs (AISC) across the JV through shared infrastructure and optimised processing pathways

• Increased plant utilisation rates, with autoclave throughput improvements contributing directly to higher gold output

The Nevada Gold Mines JV is also advancing digital transformation initiatives, incorporating data analytics and predictive technologies into its operations. Real-time monitoring systems are being used to track equipment performance, optimise maintenance schedules and reduce unplanned downtime.

These systems are particularly valuable in processing operations, where small improvements in recovery or throughput can have a significant impact on overall production and profitability.

Automation is also being progressively introduced in certain areas, improving safety and operational consistency, particularly in underground environments.

The Nevada Gold Mines joint venture represents a model for large-scale asset consolidation and optimisation in the mining industry. By combining resources, infrastructure and expertise, Newmont and Barrick have created a highly efficient and resilient operation capable of delivering sustained production.

Looking ahead, the focus will remain on improving margins, extending mine life and integrating new technologies. Exploration within the broader Nevada system also continues to identify opportunities for resource expansion, supporting long-term production.

For mining executives and investors, the NGM JV highlights the value of collaboration, scale and operational integration in maximising asset performance. It also reinforces the importance of Tier 1 assets in delivering consistent returns in an increasingly competitive global market.
