Operations Update – Curtailed Operations

The operation in Q2 2023 average d 61,637 tonnes per month of processed ore . This is a 5.0%

improvement over Q1 2023 and 96.4% more over the same period last year . Likewise, over the same

period the operation implemented an aggressive cost -reduction-plan, successfully reduc ing operating

costs by 30.3% from January to June 2023. By the end of June 2023, the operation achieved the previously

set guidance range for this year.

From January to June 2023 the realized value for the price of zinc fell by over 28% due to inflationary

pressures and broader market volatility in the global economy. Despite this scenario, the Company has

secured two term-sheets for a total of $32.5 million in aggregate funding to execute the Santander Pipe

Project.

While the company considers the macro -economic pressures affecting zinc price to be transient, CDPR

believes the best course of action is to implement a new operations plan that contemplates temporary

curtailment of the Santander operations (the “Curtailed Operations Plan”). As part of the Curtailed

Operations Plan the Company anticipates the following:

1. Santander operation will temporarily suspend production from the Magistral area until Q4 2023

and smoothly transition to a new mining contractor as outlined in the July 18th Term-Sheet signed

with China Railway N° 10 Engineering Group CO. LTD., Sucursal del Perú (“CREC10”).

2. Continue the execution of the main project items of the Santander Pipe Project, as outlined in the

Term-Sheet signed with CREC10.

3. Complete the cost -reduction-plan by executing on a contracto r and supplier cost restructuring

program.

4. Upon restarting production from Magistral in Q4 2023, mining will be limited to stope areas a t

rates that remain profitable at a low zinc price environment.

5. During the curtailed operations period t he Santander mine will benefit from other sources of

revenue such as processing external ore at its processing facilities.

6. CDPR anticipates processing of ore from the Pipe Project to start in Q1 2024. As ore mining rates

increase from the Pipe area , the Santander Mine will gradually return to normal milling

production by the end of Q2 2024.

7. During the temporary suspension of mine production from Magistral, the Company will maintain

its operations workforc e at the Santander Mine , continue with mine dewatering and all other

safety and environmental activities. The Curtailed Operation Plan will also comply with all

applicable regulations.

8. CDPR has already sent communication to its suppliers and contractors at the Santander Mine.

Furthermore, Cerro de Pasco Resources Subsidiaria del Peru SAC., a subsidiary of CDPR, submitted

on July 21st, 2023, a letter to Peruvian authorities, Direccion General de Mineria “DGM”, informing

of the temporary suspension of Magistral related activities at the Santander Mine.

Jorge Lozano, CDPR’s COO stated: “During the quarter, zinc production from our Santander operations

improved as result of higher processed tonnes , furthermore w e have achieved steady production with

significant cost optimization. Santander is well positioned for significantly higher mill production rates as

we transition to mining ore from the Pipe area. The actions taken as part of the Curtailed Operations Plan

are key to ensuring the successful execution of the Santander Pipe Project. Our operational readiness and

proven ability to secure term-sheets demonstrates the robust economics of the Pipe Project.”
