Cerro de Pasco Resources Announces Clarifications to its NI 43-101 Compliance Disclosure

MONTREAL, April 13, 2026 (GLOBE NEWSWIRE) -- Cerro de Pasco Resources Inc. (TSXV: CDPR) (OTCQB: GPPRF) (Frankfurt: N8HP) (BVL: CDPR) (the “Company”) announces that it has undertaken additional measures to ensure that its ongoing disclosure fully complies with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

In particular, these additional measures include references to disclosure relating to quantity, grade or metal content, which heretofore may have included elements such as projected operational or financial parameters. When presented individually, such information could be considered as having economic connotations prohibitive to NI 43-101. Moreover, the use of historical data that could be interpreted as current mineral resources and requires the support of a compliant technical report, at this time, has not been fulfilled due to insufficient drilling.

The aforenoted material has now been amended and replaced in the Company’s corporate presentation and website material and will be updated when the NI 43-101 compliant report is completed.

Accordingly, pursuant to the news release dated March 26, 2026 wherein CDPR announced the strategic collaboration with AMSAC, a Peruvian state-owned entity responsible for the remediation of legacy mining environmental liabilities, CDPR is now pleased to announce that it has obtained access across the full tailings footprint - enabling a comprehensive development approach - involving surface access, operational coordination and drilling activities complementing its existing concession rights over said tailings area.

The Company therefore expects to commence drilling activities shortly, with initial programs targeted for June 2026.

The Company is committed to full compliance with applicable scientific and technical disclosure requirements and is implementing enhanced internal processes to ensure the accuracy and compliance of its future public disclosure.
