Panoro Minerals Receives Payment #2 for Antilla Project Transaction

VANCOUVER, March 11, 2024 - Panoro Minerals Ltd. (TSXV: PML) (Lima: PML) (Frankfurt: PZM) ("Panoro", the "Company") announces that it has received approximately CA $2.7M ($US 2.0M) from Calisto Cobre Resources Corp. ("Calisto") as per terms of the Company's sale in December 2021 of 90% of the shares of Antilla Copper S.A., a former wholly owned subsidiary of Panoro, to Calisto.

As disclosed in its August 8, 2023 news release, the Company received Payment #1 of $CA 10.0M ($US 7.3M) on closing in December 2021 and in August 2023 agreed to amendments to the share purchase agreement and shareholders' agreement (the "Amended Agreements") with Calisto that extended the timeline for receipt of the next payment, $CA 2.8M ($US 2.1M) (the "Second Payment"), to March 31, 2024. Pursuant to the Amended Agreements, the Company received an immediate payment of $CA 300,000 ($US 226,380) made towards the Second Payment.

On March 4, 2024, Calisto paid a total of $CA 2.7M ($US 2.0M) to Panoro consisting of $CA 2.5M ($US 1.8M), the balance of the Second Payment and accrued interest at a rate of 6.7% of approximately $CA 230,000 ($US 170,370).

"Panoro is pleased to have received Payment #2 in advance of the March 31, 2024 timeline per the Amended Agreement. The cash injection will be used in updating the PEA for the Cotabambas Project to reflect the many enhancements to the project resulting from the updated mineral resource estimate announced in January 2024. The enhancements envisioned for Cotabambas include the addition of a high grade starter pit, potential reduction in initial capex with a reduced throughput start-up focused on the high grade starter pit, increased metallurgical recoveries, concentrate trucking route alternatives, reduced footprint for tailings and wasterock storage in addition to others. The updated PEA will be a snapshot for the ongoing prefeasibility studies (PFS) where several trade-off studies are already complete. The updated PEA and subsequent PFS will incorporate a new mine plan incorporating the results of the updated mineral resource estimate. These combined factors should greatly enhance the permitting and financing trajectories for the Cotabambas Project and de-risk the project development. Calisto Cobre is making steady progress at the Antilla Project, providing Panoro confidence in the timelines for the receipt of Payments #3 and #4 in 2025 and 2026."

Payment #3 of $CA 7.0M ($US 5.2M) from Calisto is payable within 12 months of Calisto obtaining drilling permits and completing land access agreements at the Antilla Project. Payment #4 will be due after Calisto completes a study of the Antilla Project with Panoro receiving 13% of the estimated Net Present Value, less the $CA 20M ($US 14.8M) total of Payments #1, #2 and #3. In addition, Panoro will retain a 10% interest in the Antilla Project plus a 2% NSR royalty and whereby if Panoro's interest in Antilla is diluted to below 5%, Panoro's interest will convert to an additional 1% NSR royalty for a total of 3% NSR royalty, subject to certain NSR buyback provisions.
