Vancouver, British Columbia--(Newsfile Corp. - November 3, 2025) -

Santacruz Silver Mining Ltd.

(TSXV: SCZ) (OTCQX: SCZMF) (FSE: 1SZ)

("

Santacruz

" or the "

Company

") reports its Q3 2025

production results from its Bolívar mine, Porco mine, Caballo Blanco Group of mines ("

Caballo

Blanco

") and the San Lucas Group which includes the Reserva Mina and the San Lucas feed sourcing

business ("

San Lucas

"), all located in Bolivia, and the Zimapan mine located in Mexico.

Q3 2025 Production Highlights:

Silver Equivalent Production:

3,424,817 silver equivalent ounces

Silver Production:

1,241,929 ounces

Zinc Production:

21,581 tonnes

Lead Production:

2,603 tonnes

Copper Production:

331 tonnes

Underground Development:

12,634 meters

Arturo Préstamo, Executive Chairman and CEO of Santacruz, commented, "During Q3 2025, Santacruz

maintained steady consolidated production, supported by strong operational performance from Caballo

Blanco and San Lucas, which helped offset the lower silver production at the Bolívar mine. In Mexico,

Zimapán continued to deliver stable production, reflecting consistent plant throughput and recoveries.

This quarter fully captured the impacts of the water inflow event that occurred at the Bolívar Mine in May

2025. The event resulted in restricted access to the high silver grade areas. In response, we have been

actively working on strengthening the pumping system at Bolívar, with the fourth line commissioned in

September and the installation of a fifth submersible line underway, which together will increase total

pumping capacity to 340 liters per second (l/s). These improvements are facilitating the gradual

dewatering and recovery of the affected zones in the Bolívar mine. We expect production from the high-

grade Pomabamba and Nané areas at Bolívar to resume in February 2026 and ramp up steadily through

the remainder of the year."

Bolivar is presented at 100% whereas the Company records 45% of revenues and expenses in its consolidated financial statements.

(2)

Silver Equivalent Produced (ounces) have been calculated using prices of $31.41/oz, $2,775.53/t and $2,085.90/t for silver, zinc and lead respectively

applied to the metal production divided by the silver price as stated here.

Q3 2025 vs Q2 2025

In Q3 2025, Bolívar's performance reflected the ongoing impact of the water inflow event that occurred in

mid-May 2025 and continued to restrict access to the high silver head grade Pomabamba and Nané

areas. Silver equivalent production decreased (-30%) due to lower silver head grade (-53%) and

reduced silver output (-57%). Rehabilitation and dewatering advanced steadily during the quarter, with

the fourth pumping line commissioned in September 2025, increasing total capacity to around 300 l/s

and enabling a gradual reduction in water levels. In parallel, installation of the fifth submersible pumping

line began in mid-October, targeting a combined capacity of 340 l/s to accelerate recovery efforts and

restore full access to the high silver head grade Pomabamba and Nané zones, where production is

expected to resume in February 2026. The installation schedule experienced a delay due to logistics

related to the delivery of the purchased water pumps. Additionally, drilling above Level 340 began in

October 2025 to expand resources toward the southern extension of Pomabamba.

Q3 2025 vs Q3 2024

On a year-over-year basis, Bolívar's performance remained constrained by restricted access to

Pomabamba following the May flooding event, with silver equivalent production down (-54%), silver head

grade (-62%), recoveries (-4%), and silver production (-73%) all declining. Progress on dewatering

continued, with the fifth pumping line expected to be fully operational by year-end, enabling access to the

Pomabamba South vein, which contains reserves with high silver head grades, averaging 309 g/t Ag.

Production from this area is expected to resume in February 2026, significantly improving Bolívar's

overall silver grade profile.

Porco is presented at 100% whereas the Company records 45% of revenues and expenses in its consolidated financial statements.

(2)

Silver Equivalent Produced (ounces) have been calculated using prices of $31.41/oz, $2,775.53/t and $2,085.90/t for silver, zinc and lead respectively

applied to the metal production divided by the silver price as stated here.

Q3 2025 vs Q2 2025

Porco, the Company's predominantly zinc underground mine, reported an 11% decrease in zinc

production compared to the previous quarter, mainly due to a 10% decline in zinc head grade.

Throughput remained steady and zinc recoveries were stable at 93%, supported by ongoing

metallurgical optimization and consistent plant performance. Silver output declined, as operations

continued to target zinc-rich zones consistent with Porco's production focus.

Q3 2025 vs Q3 2024

Porco recorded a 5% year-over-year decrease in zinc production, reflecting slightly lower zinc grades

and stable throughput levels. Zinc recoveries remained strong (93%), demonstrating solid process

control and operational efficiency. The mine plan during 2025 prioritized zinc-dominant zones with lower

silver content, resulting in a reduction (-47%) in silver production compared to Q3 2024. Overall, Porco

continues to perform as a reliable zinc-producing asset, maintaining stable operations and strong

metallurgical performance.

The Caballo Blanco Group consists of the Colquechaquita and Tres Amigos mines.

(1)

Silver Equivalent Produced (ounces) have been calculated using prices of $31.41/oz, $2,775.53/t and $2,085.90/t for silver, zinc and lead respectively

applied to the metal production divided by the silver price as stated here.

Q3 2025 vs Q2 2025

Caballo Blanco's production for the quarter benefited from higher milled tonnes (+8%), leading to a 3%

increase in silver equivalent and stable silver production. The silver head grade declined moderately (-

5%), resulting in a slight reduction in recoveries (-2%).

Q3 2025 vs Q3 2024

Compared with Q3 2024, Caballo Blanco's operational improvements resulted in silver equivalent

production up 9% and silver output up 18%, supported by annual silver head grade growth (+8%) and

recoveries (+3%). These improvements reflect ongoing plant and mining optimizations.

respectively applied to the metal production divided by the silver price as stated here.

Q3 2025 vs Q2 2025

San Lucas continued to play a strategic support role this quarter, with processed ore up 6%. Silver

equivalent production increased (+5%), and silver output was up (+2%). The operation's flexibility and

reliable throughput helped offset the negative impacts of reduced volumes and grades at Bolívar,

especially in the context of the ongoing rehabilitation and restricted access to silver high-grade areas.

Slight head grade improvement (+2%) and steady recoveries (-6%) contributed to overall plant efficiency

for the group.

Q3 2025 vs Q3 2024

On an annual basis, San Lucas's support was crucial for sustaining group-level throughput and mitigating

Bolívar's production losses. Silver equivalent production slipped 6%, silver output declined 8%, and

processed tonnes increased 5%. The modest drop in silver head grade (-6%) and recoveries (-6%)

continued trends from previous quarters, but operational flexibility and the crucial support to Bolívar were

key to maintaining stable results across Santacruz's Bolivian operations.

Silver Equivalent Produced (ounces) have been calculated using prices of $31.41/oz, $2,775.53/t, $,2085.90/t and $9,762.69/t for silver, zinc, lead

and copper respectively applied to the metal production divided by the silver price as stated here.

Q3 2025 vs Q2 2025

Zimapan posted a 3% increase in silver equivalent output and a 5% rise in zinc, with lead up 19% and

copper up 45% on steady throughput (+1%). Silver head grade and recoveries were stable (-1%), and

production gains were driven by higher grades in zinc.

Q3 2025 vs Q3 2024

Year-on-year, Zimapan's silver equivalent production declined (-2%), largely due to a decrease in silver

head grade (-6%) and a decline in recoveries (-7%). Despite this, zinc was up 10% strengthened on

targeted stope development and improvements in feed quality.
