Corporate Updates

PRESS RELEASE

Cerro de Pasco Resources Inc. Announces Execution of Settlement

Agreement with Trevali Monitor

Montréal, Québec, Canada – December 12, 2025 – Cerro de Pasco Resources Inc. (“CDPR” or

the “Company”) announces that it has entered into a settlement agreement (the “Settlement

Agreement”) with FTI Consulting Canada Inc., in its capacity as court -appointed monitor of

Trevali Mining Corporation (the “Monitor”), and with Trevali Mining Corporation (“Trevali”),

resolving all claims and counterclaims in the arbitration relating to the Share P urchase

Agreement for Trevali Peru S.A.C. and the Santander Mine (the “Settlement”).

The Settlement is subject to court approval , as Trevali remains in creditor protection under the

Companies’ Creditors Arrangement Act. The Monitor is bringing an application in the Supreme

Court of British Columbia set to be heard December 16, 2025 for approval of the Settlement.

Background

As disclosed in the Company’s financial statements, CDPR recorded a purchase price payable

and a contingent consideration payable associated with the 2021 acquisition of the Santander

Mine. These amounts have been the subject of a dispute between CDPR and Trevali, as previously

disclosed. In December 2024 , the Monitor commenced arbitration proceedings related to this

dispute. CDPR responded to the claim in February 2025 and brought a counterclaim seeking to

set off any amounts found to be due and owing to T revali against losses incurred by CDPR in

relation to the Santander Mine acquisition.

Settlement Summary

Under the terms of the signed Settlement:

• Following court approval, the parties will jointly instruct the arbitrator to terminate the

arbitration and release the CAD 700,000 security for costs back to the Monitor.

• CDPR will pay CAD 2,000,000 in full and final settlement of all claims brought by Trevali

and the Monitor, within 10 days of the issuance of the arbitrator’s termination order.

• All claims and counterclaims between the parties will be mutually released.

• Each party will bear its own legal costs and both will share equally any remaining

arbitrator fees.

The Company believes this resolution is an important step in advancing its strategic objectives

and focusing fully on its core operations and development initiatives.

Strengthening CDPR’s Financial Position

After court approval, CDPR will eliminate all Trevali -related liabilities recorded on its balance

sheet, including a purchase price payable of USD 1,584,164 and a contingent consideration

payable of USD 2,500,000 as disclosed in the Company’s financial sta tements. The removal of

these items represents a total reduction of USD 4,084,164 and is expected to result in a material

gain on settlement when reflected in CDPR’s financial reporting.
