Cerro de Pasco Resources has won a public auction run by Peru's state-owned AMSAC for the Quiulacocha tailings, which it plans to reprocess for their metal content. The award still needs definitive agreements, expected within days.
At a glance
- The win would give the company both the mineral and surface rights over the tailings.
- Together with its El Metalurgista concession, it would consolidate the rights needed for the project.
- The company is working towards a first mineral resource estimate and feasibility-level studies.
Background
Tailings are the ground-up rock left after metals are extracted. Older tailings often still contain valuable metals that modern processing can recover. Cerro de Pasco in central Peru has been mined for more than a century, leaving large tailings deposits. AMSAC is the Peruvian state company that cleans up legacy mining sites.
What happened
Cerro de Pasco Resources said AMSAC's sale committee awarded Public Auction No. 001-2026-AMSAC to its Peruvian subsidiary on October 12. The auction covered the tailings in the Quiulacocha Tailings Storage Facility, in the Simón Bolívar district of Pasco, together with the surface rights needed to reprocess them.
The award is subject to definitive agreements with AMSAC, which the company expects to sign in the coming days.
Why it matters
Once the agreements are signed, the company expects to hold both the mineral and surface rights over Quiulacocha. Combined with its wholly owned El Metalurgista concession, that would consolidate all the rights it needs for the Quiulacocha Tailings Reprocessing Project.
The company said the tailings host a polymetallic mineral inventory including several critical minerals. Reprocessing them is expected to add to metal supply while dealing with one of Peru's large legacy mining liabilities.
What comes next
Cerro de Pasco Resources is running a technical programme at Quiulacocha towards a maiden mineral resource estimate and feasibility-level studies. Its El Metalurgista concession hosts silver-rich tailings and stockpiles from more than a century of mining.
Our read
Outlook: neutral. The project is at an early stage and will not add metal supply for years.
What to watch
- Signing of the definitive agreements with AMSAC.
- A maiden mineral resource estimate for Quiulacocha.
- Feasibility-level studies on reprocessing.

Detailed analysis
Timeline
- 2026-10-12: AMSAC awards the Quiulacocha tailings auction to Cerro de Pasco Resources.
Supply Drivers
Reprocessing old tailings could add silver and other metals without opening a new mine.
Government Policies
Peru allows AMSAC to transfer old tailings to private companies for economic use.
What could lift prices
- The award consolidates the rights the project needs.
- Reprocessing also cleans up a legacy environmental liability.
What could weigh on prices
- There is no resource estimate or feasibility study yet.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Peru | Medium | A large legacy tailings site could be reprocessed and cleaned up. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Mining | Positive | Old tailings become a source of metal supply. |
Who gains, who loses
- Cerro de Pasco Resources: It gains the rights it needs for its tailings project.
Other ways this could play out
- If the agreements are signed and studies are positive, reprocessing could move towards production.
- If studies show low recoveries, the project may not be economic.
Price risks
- Metal prices affect whether reprocessing pays.
- Permitting and community issues could slow the project.
Technical view
Price is trading below both its 20-period and 50-period moving averages, a bearish alignment.
