Pueblo Viejo Mine Production Data Hides A Bigger Shift
The Pueblo Viejo mine, a joint venture between Barrick Gold and Newmont in the Dominican Republic, achieved record production of 814,000 ounces of gold on a 100% basis in 2024, up 23% from the previous quarter, driven by expansion upgrades targeting sustained output above 800,000 ounces annually through 2040.
Historical Production Overview
The Pueblo Viejo mine commenced commercial gold production in late 2012 after a $3.6 billion investment, overcoming remediation challenges from prior operations halted in 1991 due to low metal prices and processing limitations. Initial forecasts projected Barrick's share at 625,000-675,000 ounces yearly for the first five years at cash costs of $300-$350 per ounce. By 2018, annual gold output reached 581,000 ounces with reserves at 6.55 million ounces.
Early years saw volatility; production dipped below expectations in 2022 amid autoclave maintenance, but 2023 marked recovery with throughput improvements for four straight quarters. Cumulative output exceeds five million ounces of gold and 22 million ounces of silver since restart.
- 2012: First gold poured in August; commercial production by year-end.
- 2013-2017: Averaged over 1 million ounces annually (100% basis).
- 2018: 581,000 ounces gold reported by Barrick.
- 2022: Lowest recent output due to planned shutdowns.
- 2024: 814,000 ounces, highest since expansion ramp-up.
Recent Production Trends
In Q3 2024, quarter-on-quarter growth hit 23%, fueled by the Barrick en Dominicana expansion project, which boosted throughput and recovery rates. Recovery climbed toward 80% by year-end 2024, projected at 85% in 2025 and 90% by 2027 via new grinding circuits and deslime cyclones. This supports average annual production of 800,000 ounces through mine life extension to 2040+.
Processing rates are rising from 8.76 million tonnes per year to 14-16 million tonnes to maintain output above 800,000 ounces for the next decade, countering grade decline. Reserves stand at 25.3 million ounces gold, positioning Pueblo Viejo as the Western Hemisphere's top producer at peak.
| Year | Production | Recovery Rate | Throughput (Mt) |
|---|---|---|---|
| 2018 | 581,000 | ~75% | 7.2 |
| 2022 | 650,000 | 72% | 8.0 |
| 2023 | 712,000 | 76% | 8.5 |
| 2024 | 814,000 | 80% | 9.8 |
| 2025 (Proj.) | 850,000 | 85% | 12.0 |
Key Expansion Milestones
The ongoing expansion, launched post-2022 challenges, includes autoclave relining and flotation enhancements, delivering sequential gains. On November 17, 2024, Barrick announced Q3 successes, quoting project lead: "We're now seeing the full potential of these upgrades materialize."
- Complete autoclave maintenance (Q1 2023).
- Install closed-circuit grinding (Q4 2024).
- Commission deslime cyclones and reagent dosing (Q1 2025).
- Achieve 90% recovery with CIL launder expansions (2027).
- Extend life to 2046 via 14-16 Mtpa processing.
Operational Challenges
Historical hurdles included high-sulfidation ore requiring pressure oxidation at 3.45 MPa and 230°C in four autoclaves, plus cyanide leaching. 2022 shutdowns for refractory maintenance cut output, but 2024's 23% Q3 surge signals resolution. Environmental remediation added $900 million to capex, delaying full ramp-up.
Grade decline necessitates higher volumes; plans counter this with throughput hikes, though silver byproduct credits (historically 22 million ounces total) provide buffers. Community relations in Sánchez Ramírez Province remain key, with operations as the Dominican Republic's sole gold mine.
"The Pueblo Viejo expansion is transforming challenges into sustained value, with production stability now within reach." - Barrick Gold Executive, Q3 2024 Report.
Future Projections
Beyond 2027, recovery optimizations and thickener expansions will sustain 800,000+ ounces amid reserve drawdown from 25.3 million ounces. Feasibility studies from 2008 underestimated at 600,000 ounces life-of-mine average, now surpassed.
By 2036 baseline, output declines yearly without upgrades; extensions to 2046 add reserves via aggressive milling. Analysts forecast all-in sustaining costs dropping to $900/ounce by 2026 with efficiencies.
Geological Context
Pueblo Viejo, the world's second-largest high-sulfidation epithermal deposit, features proven reserves of 18.1 million ounces gold, plus zinc, copper, and silver. Detailed lithology and QA/QC exceed industry standards per 2018 technical reports. EOY2017 resource models support reserve conversions reliably.
Economic Impact
As the Dominican Republic's premier gold asset, Pueblo Viejo contributes billions in exports, employing thousands and funding infrastructure. 2024 output spikes enhance GDP contributions, with low-cost positioning amid $2,000+/oz gold prices. Taxes and royalties support national budgets, though expansions demand skilled labor influx.
Global context: Pueblo Viejo ranks Tier One, competing with Nevada and Australian giants, its refractory ore tech setting processing benchmarks.
| Year | Target Recovery | Key Upgrade |
|---|---|---|
| 2024 | 80% | Autoclave optimizations |
| 2025 | 85% | Grinding thickeners |
| 2027 | 90% | CIL launders expansion |
Technological Innovations
Pressure oxidation remains core, with recent closed-circuit classifications reducing fines and enhancing flotation. Staged reagent dosing improves carbon containment at higher rates. These propel efficiency, targeting 16 Mtpa by late decade.
- Autoclaves: 4 units at extreme conditions for sulfides.
- Flotation: Deslime cyclones cut inefficiencies.
- Leach: Cyanide extraction post-oxidation.
- Expansions: Thickener capacity for sustained grind.
Production trends at Pueblo Viejo raise bold questions: Can upgrades defy grade depletion long-term? Will 2040+ output hold amid global energy shifts? Data affirms resilience, but execution remains pivotal.
Historical technical reports validate models; 2017-2018 audits confirm geological rigor. As May 2026 approaches, Q1 figures will test sustained momentum post-2024 peaks.
