MINEROS REPORTS STRONG Q2 2026 SALES OF 61,849 GOLD EQUIVALENT OUNCES;

REVISES FULL-YEAR GUIDANCE TO 220,000 - 240,000 OUNCES

MEDELLÍN, COLOMBIA – July 7, 2026 – Mineros S.A. (TSX:MSA, OTCQX:MNSAF, BVC:MINEROS) (“Mineros”

or the “Company”) is pleased to report its gold sold for the three months ended June 30, 2026 (“Q2 2026”)

and revised guidance for 2026.

Daniel Henao, President and CEO of Mineros, commented: “The second quarter results demonstrate the

strength and consistency of our operations across both jurisdictions. In Nicaragua, production increased

and reflects the sustained success of our metallurgical optimization program and the significant by-

product value embedded in our operations. These are not isolated gains; they are the product of

deliberate and disciplined investment in our plant and our people. In Colombia, gold sold of 22,482

ounces represented an 8% year-over-year increase, reflecting encouraging operational improvements.

With 122,634 gold equivalent ounces sold in the first half of 2026, we have strong confidence in our full-

year trajectory, and we are pleased to raise the top end of our 2026 consolidated production guidance to

240,000 ounces. The fundamentals of our business — disciplined operations, a growing and increasingly

productive asset base, and a robust gold price environment — position Mineros well to continue

delivering value for our shareholders.”

Q2 2026 Highlights

● Strong quarterly gold sold: 59,639 ounces of gold, an 11% increase over the 53,906 ounces sold in

Q2 2025, driven by continued operational optimizations in Nicaragua and Colombia.

● Record silver sold: 150,680 ounces of silver, more than double the 70,732 ounces sold in Q2 2025, a

113% year-over-year increase driven by sustained improvements in metallurgical recovery at the

Hemco processing plant.

● Solid gold equivalent output: AuEq¹ sold of 61,849 ounces, a 13% increase over the 54,629 AuEq

ounces delivered in Q2 2025.

● Hemco outperformance: The Hemco Property in Nicaragua continued to set the pace with 37,157

ounces of gold, a 12% year-over-year increase, and silver sold of 148,565 ounces — more than

double the prior-year period. Processing capacity continued to advance toward the targeted 2,500

tonnes per day by year-end.

● Guidance upgrade: With 122,634 AuEq ounces sold in the first half of 2026, a 12% increase over the

same period last year, the Company is raising the top end of its full-year 2026 consolidated gold

production guidance to 240,000 ounces.

Operational Review

Mineros delivered a strong second quarter, with consolidated gold sold of 59,639 ounces, an 11% year-over-

year increase. Plant optimization at Hemco, mine ramp -up and operational improvements at Nechí drove

another quarter of production growth. Combined with a 113% increase in silver sold to 150,680 ounces, the

quarter underscores the Company’s ability to extract growing value from its existing asset base. Safety and

environmental performance remained central to the Company’s operational philosophy throughout the

period.

At the Hemco Property (Nicaragua), the Company’s principal growth engine delivered another strong quarter.

Gold sold reached 37,157 ounces, a 12% increase over Q2 2025, driven by higher throughput, improved

metallurgical recoveries, and strong ore feed from Bonanza Mining Partners and the Company-operated mines.

Silver sold of 148,565 ounces — more than double the prior- year period — reflects the sustained success of

the Company’s metallurgical optimization program. Processing throughput continued to advance toward the

2,500 tpd target set for year-end, building the foundation for continued production growth in the second half.

At the Nechí Property (Colombia) , the operation delivered 22,482 ounces of gold, a n 8% increase over Q2

2025, demonstrating a solid recovery trajectory and continued operational momentum. The Company is

advancing continuous improvements to production rate and metallurgical recovery across its operations, while

expanding contributions from partner operational units. The Nechí Property continues to generate reliable

cash flows underpinned by a disciplined AISC framework.

¹ Gold equivalent (“AuEq”) is calculated using silver production for the quarter multiplied by the average realized silver price per ounce sold,

divided by the average realized gold price per ounce sold for the respective period. Silver is treated as a by-product and represents a minor

portion of consolidated output; silver production guidance is not provided. Figures may not sum due to rounding.

Updated 2026 Production Guidance

On the strength of its first -half operating performance, Mineros is raising its full- year 2026 consolidated gold

production guidance to 220 ,000 to 240,000 ounces — an increase of 7,000 ounces at the top end relative to

the original guidance of 213,000 to 233,000 ounces issued on February 6, 2026. The revision reflects sustained

metallurgical outperformance and continued throughput gains at the Hemco Property and demonstrates the

Company’s ability to convert operational momentum into growth.

When compared with guidance, first-half gold sold was 117,489 ounces (122,634 AuEq). Guidance for the Nechí

Property (Colombia) remains unchanged at 83,000 to 93,000 ounces, underpinned by a stable operating plan.

The upper end of the Hemco Property (Nicaragua) guidance is revised to 13 7,000–147,000 ounces (from the

130,000–140,000 range previously indicated), reflecting the performance delivered through the first half of the

year.

Note to Guidance: The gold price assumed was USD $4,405 per ounce. The revised guidance for the Hemco

Property reflects continued plant -capacity expansion and improved metallurgical recoveries. The Company

continues to optimize silver recovery at the Hemco processing plant; any silver recovered is reported as gold

equivalent (AuEq) sold using the then-prevailing average realized price per ounce sold of each metal. Silver is

not currently classified as a Mineral Reserve or Mineral Resource.
