New Pacific Metals Corp. updated the preliminary economic assessment for its Silver Fox deposit in Bolivia on July 17, 2026. The revised study shows a substantial improvement in the project's projected net present value, which increased 29% to $1.28 billion. The after-tax internal rate of return rose to 20.4%. The update incorporates optimized mine planning and higher recoveries for silver and gold, reinforcing the project's potential scale within the global silver development pipeline.
Context — Why this matters now
The updated PEA arrives during a period of structural tightness in the global silver market. Silver supply from primary mines has been stagnant for several years, with production growth lagging behind industrial demand from the solar photovoltaic and electronics sectors. The Silver Fox project is positioned as a potential large-scale, long-life asset that could help alleviate future supply deficits.
Major mining companies have shown renewed interest in high-quality silver development assets since 2024. In May 2025, SSR Mining acquired the Puna Operations in Argentina for $525 million, highlighting the premium for long-life silver exposure. Pan American Silver also expanded its portfolio through the acquisition of Yamana Gold's assets in 2023 for $4.8 billion. This consolidation trend creates a favorable backdrop for well-advanced projects like Silver Fox.
The catalyst for the PEA update was the completion of 30,000 meters of infill drilling in late 2025. That drilling campaign successfully converted a significant portion of inferred resources to the higher-confidence indicated category. This resource upgrade provided the geological confidence needed for more detailed and aggressive mine plan optimization in the new study.
Data — What the numbers show
The 2026 PEA presents materially stronger economics compared to the prior 2024 study. The after-tax net present value, using an 8% discount rate, increased from $996 million to $1.28 billion. The internal rate of return improved from 17.9% to 20.4%. The study uses a base case silver price of $26.50 per ounce and a gold price of $1,850 per ounce.
Initial capital expenditure is estimated at $798 million, a slight increase from the previous $752 million estimate. However, the payback period on that capital improved significantly, dropping from 4.2 years to 3.5 years. Life-of-mine all-in sustaining costs are projected at $13.85 per silver equivalent ounce, an improvement from the previous $14.20 estimate.
| Metric | 2024 PEA | 2026 PEA | Change |
|---|
| After-Tax NPV (8%) | $996M | $1.28B | +$284M |
| After-Tax IRR | 17.9% | 20.4% | +2.5 pts |
| Payback Period | 4.2 years | 3.5 years | -0.7 years |
Average annual silver production over the first 10 years is estimated at 21 million ounces, positioning Silver Fox among the largest undeveloped primary silver projects globally. This compares to the current annual output of 25-30 million ounces from the world's largest primary silver mine, Fresnillo's Saucito operation in Mexico.
Analysis — What it means for markets / sectors / tickers
The improved economics directly benefit New Pacific Metals [NUAG.TO] and its primary shareholder, Silvercorp Metals Inc. [SVM.TO]. Silvercorp owns approximately 28% of New Pacific and provides technical management, meaning its expertise is validated by the study's success. A successful development of Silver Fox could significantly increase Silvercorp's net asset value and production profile beyond its current Chinese operations.
Silver streaming and royalty companies represent a secondary beneficiary group. Firms like Wheaton Precious Metals [WPM] and Franco-Nevada [FNV] may view Silver Fox as a future candidate for a streaming agreement to provide development capital. A positive feasibility study could attract a streaming deal worth several hundred million dollars, a common funding mechanism for large-scale precious metals projects.
A key risk acknowledged in the analysis is Bolivia's evolving mining investment climate. While the government has expressed support for foreign investment in the sector, the country's history of resource nationalism and complex community relations presents execution risk. The project's success is contingent on maintaining a stable fiscal and regulatory framework through a multi-year construction period.
Positioning data shows institutional interest growing in mid-tier development silver stocks. Exchange-traded fund flows into the Global X Silver Miners ETF [SIL] turned positive in Q2 2026, with a net inflow of $47 million. Hedge funds have been accumulating shares in developers with strong economics, anticipating a wave of merger and acquisition activity as majors seek to replen reserves.
Outlook — What to watch next
The next major catalyst is the commencement of the definitive feasibility study, expected to be announced before the end of 2026. The DFS will require an additional 50,000 meters of drilling and more detailed engineering, taking approximately 18-24 months to complete. Its results will determine the final project design and capital cost accuracy, moving Silver Fox closer to a construction decision.
Investors should monitor the quarterly results of Silvercorp Metals for commentary on the Silver Fox project's progress and any updates on exploration drilling at nearby targets. The next earnings call is scheduled for early August 2026. Key levels to watch for New Pacific's share price are the CAD $4.20 support level, established after the PEA release, and the CAD $5.80 resistance level from its 2025 high.
The long-term outlook hinges on the silver price. The project's economics are highly sensitive to metal prices, with the PEA showing the NPV could exceed $2.0 billion at a $30 per ounce silver price. The quarterly World Silver Survey from the Silver Institute, next due in October 2026, will provide critical data on supply-demand fundamentals. A confirmation of sustained industrial deficits would further improve the investment case for new mine development.
Frequently Asked Questions
What is a PEA and why is it important for mining stocks?
A Preliminary Economic Assessment is an early-stage technical study that evaluates the potential economic viability of a mineral project. It uses inferred mineral resources and provides initial estimates on capital costs, operating costs, and projected financial returns like NPV and IRR. For mining stocks like New Pacific, a positive PEA de-risks the project, attracts investor interest, and provides a benchmark for valuation. It is a required step before committing to the more expensive and detailed Feasibility Study.
