    New Pacific’s Carangas NPV uplift: capex, returns and risk notes for mine planners

    New Pacific’s Carangas NPV uplift: capex, returns and risk notes for mine planners

    First reported on MINING.com

    30 Second Briefing

    New Pacific Metals has lifted the Carangas silver-gold project’s after-tax NPV to US$2.65 billion in an updated PEA by Ausenco, outlining average annual output of nearly 18 million oz silver-equivalent over a 19-year mine life at projected all-in sustaining costs of US$19.16/oz. The study, based on US$45/oz silver and US$3,400/oz gold, delivers a 35.9% after-tax IRR, 2.4-year payback on US$644.5 million initial capex, and total production of 339 million silver-equivalent oz including 1.1 million oz gold. New Pacific plans a 30,000-metre infill drill programme while navigating Bolivia’s fuel, FX and permitting constraints.

    Technical Brief

    • Life-of-mine payable production totals 195 Moz silver, 1.1 Moz gold, 1.45 Blb zinc and 0.94 Blb lead.
    • New Pacific plans 30,000 m of infill drilling to upgrade inferred resources to indicated for future studies.
    • Conversion of current exploration licences into “administrative mining contracts” is a precondition for full development and long-term tenure.
    • Environmental approvals hinge on initiating and completing a formal environmental impact assessment process under Bolivian regulations.
    • BMO Capital Markets lifted its Carangas net asset value estimate by 13% on the back of higher throughput and added gold.
    • Analyst commentary flags permitting risk and resource classification upgrades as the next key de-risking steps for the project.
    • Country-level constraints include fuel shortages, foreign exchange controls, regulatory uncertainty and slow permitting, all affecting project execution planning.

    Our Take

    Ausenco’s role at Carangas aligns with its recent mandates on gold and copper projects like DeLamar (Idaho) and Hillside (South Australia), signalling that New Pacific Metals is tapping a contractor with a current track record of taking complex precious-metal projects through detailed engineering and EPCM stages.

    With an after-tax IRR of 35.9% and a 2.4-year payback on US$644.5 million of initial capital, Carangas screens as a relatively high-return, mid-capex Latin American silver-gold project in our database, which is likely to appeal to lenders and stream/royalty financiers even in a higher-cost environment.

    The polymetallic mix at Carangas (silver, gold, zinc, lead) contrasts with the lithium focus of Sigma Lithium also mentioned here, underlining how Bolivia’s project pipeline in our coverage is diversifying beyond brine lithium towards large-scale precious and base metal developments.

    Yellowhead copper project consent deal: assessment and cost lens for mine planners

    British Columbia and the Simpcw First Nation have signed a consent-based agreement to govern the environmental assessment of Trekor Metals’ Yellowhead copper project in Simpcwul’ecw Territory, the first time Simpcw has applied its Indigenous-led consent process to a major mine. Trekor has submitted a Detailed Project Description to the BC Environmental Assessment Office after early engagement and additional technical work, alongside an economic impact study for construction and operations. The proposed open pit is scoped as a 90,000 t/d operation over 25 years, targeting 178 million lb/y copper at US$1.90/lb cash costs, rising to 206 million lb/y at US$1.62/lb in the first five years.

    Mining M&A wave: project quality, timelines and value signals for engineers

    Mining’s next two years will be dominated by mergers and acquisitions as producers with strengthened balance sheets but thin project pipelines move to buy reserves after a decade of underinvestment, veteran investor Rick Rule told The Northern Miner at the 2026 Rule Symposium in Boca Raton. Rule expects intensified takeover interest in copper, uranium and gold developers holding permitted or near-build assets, as long mine discovery-to-production timelines collide with tightening supply. Projects with genuine scale, robust economics and proven management teams are likely to command premium valuations.

    China gold demand at decade low: WGC signals price and project risks for miners

    China’s physical gold demand stayed near decade lows in June, with Shanghai Gold Exchange withdrawals at 87 tonnes, up 36% on May but still 27% below the 10-year average for H1 2026 as total withdrawals reached 598 tonnes. Jewellery demand weakness is keeping manufacturers from rebuilding inventories even as the gold price holds around $4,013/oz, roughly 8% lower year-to-date. In contrast, the People’s Bank of China added 15 tonnes in June, lifting reserves to 2,346 tonnes, while domestic gold ETFs saw record monthly outflows of RMB 15 billion and a 17-tonne holdings drop to 277 tonnes.
