**[Fresnillo PLC](https://www.directorstalkinterviews.com/ftse-company/fresnillo-plc/fres.l)**(
LON:FRES) has announced its first quarter production report for the three months
ended 31 March 2024.

> **Octavio Alvídrez, Chief Executive Officer, said:**
> “We have started the year with our performance in line with our expectations. 
> Silver production was slightly up over the same quarter last year, driven by the
> contribution of Juanicipio, higher grades at San Julián Veins and a stronger performance
> at Saucito. Gold production was slightly lower as expected, due mainly to the 
> lower output from the Noche Buena mine as it approaches its end of life and the
> lower grade at Herradura in line with the mine plan. We continue to prioritise
> safety across all our operations in 2024, while also focusing on reducing costs,
> improving efficiencies at all mine sites, and with our newest Juanicipio mine 
> now fully ramped up, on the advancement of our growth pipeline. Our guidance for
> the full year is unchanged.”

**HIGHLIGHTS**

**Silver**

·    Quarterly attributable silver production of 13.5 moz (including Silverstream)
decreased 4.6% vs. 4Q23 due to the lower ore grade and, to a lesser extent, decreased
volume of ore processed at San Julián (DOB), and lower ore grade at Saucito and 
Fresnillo, mitigated by the higher ore grade at San Julián Veins.

·    Quarterly attributable silver production (including Silverstream) increased
2.7% vs. 1Q23, primarily due to the increased contribution from Juanicipio, the 
higher ore grade at San Julián Veins and increased volume of ore processed at Saucito,
partly offset by the lower ore grade and volume of ore processed at Fresnillo and
San Julián (DOB).

**Gold**

·    Quarterly attributable gold production of 140.8 koz, down 7.7% vs. 4Q23, mainly
driven by the lower ore grade at Herradura in line with the mine plan, and the mine
closure plan at Noche Buena, partly mitigated by the higher ore grade at Saucito.

·    Quarterly attributable gold production down 18.6% vs. 1Q23 primarily due to
the lower volume of ore processed at Herradura and the mine closure plan at Noche
Buena, partly mitigated by the increased contribution from Juanicipio.

**By-Products**

•     Quarterly attributable by-product lead production down 6.1% vs. 4Q23 primarily
due to the lower ore grade at Saucito and lower ore grade, decreased volume of ore
processed and lower recovery rate at San Julián (DOB), partly mitigated by the higher
ore grade and recovery rate at Fresnillo.

•     Quarterly attributable by-product lead production up 11.6% vs. 1Q23 due to
the increased contribution from Juanicipio and the higher volume of ore processed
at Saucito, partly offset by the lower ore grade, volume of ore processed and recovery
rate at San Julián (DOB).

•     Quarterly attributable by-product zinc production down 9.3% vs. 4Q23 mainly
due to the lower ore grade at Saucito, partly mitigated by the higher ore grade 
at Fresnillo.

•     Quarterly attributable by-product zinc production up 8.5% vs. 1Q23 due to 
the increased contribution from Juanicipio and the higher volume of ore processed
at Saucito, partly offset by the lower ore grade and volume of ore processed at 
San Julián (DOB) and decreased volume of ore processed at Fresnillo.

|  | **1Q24** | **4Q23** | **% Change** | **1Q23** | **% Change** | 
| Silver (koz) | 13,117 | 13,548 | (3.2) | 12,337 | 6.3 | 
| Silverstream (koz) | 397 | 612 | (35.1) | 821 | (51.6) | 
| Total Silver (koz) | 13,513 | 14,161 | (4.6) | 13,158 | 2.7 | 
| Gold (oz) | 140,847 | 152,605 | (7.7) | 173,034 | (18.6) | 
| Lead (t) | 14,924 | 15,895 | (6.1) | 13,368 | 11.6 | 
| Zinc (t) | 26,157 | 28,844 | (9.3) | 24,118 | 8.5 |

**SAFETY PERFORMANCE**

As already reported in the Preliminary Results, we were deeply saddened to confirm
a fatal accident at the Fresnillo mine in January. A thorough investigation of the
incident was carried out, together with the authorities, to identify the root cause
and implement corrective actions. The safety of our people, and the installation
of a true safety culture across all our operations for both employees and contractors,
remains the absolute priority for the Group.  

**2024 OUTLOOK**

Our 2024 outlook is in line with previous expectations:

·    Attributable silver production expected to be in the range of 55.0 to 62.0 
moz (including Silverstream)

·    Attributable gold production expected to be in the range of 580 to 630 koz.

Expressed in silver equivalent ounces^([1]), total production is expected to be 
101-112 million ounces.

| **Ore Grades** |  |  |  |  |  | 
| Silver (g/t) | 151 | 160 | (5.6) | 184 | (17.9) | 
| Gold (g/t) | 0.66 | 0.59 | 11.9 | 0.57 | 15.8 |

| Zinc (%) | 2.58 | 2.42 | 6.6 | 2.42 | 6.6 |

Quarterly silver production decreased 3.8% when compared to 4Q23, mainly driven 
by the higher proportion of volumes extracted from the western areas of the mine
with lower silver ore grade but higher gold and base metal contents, the temporary
operating constraints in the eastern areas, including ground conditions and delays
in mine infrastructure and, to a lesser extent, variations with the geological model.
This was partly mitigated by the increased volume of ore processed from these areas.

Quarterly silver production decreased 24.8% vs. 1Q23, mainly due to the lower ore
grade as explained above and lower volume of ore processed in accordance with the
mine plan. 

Mine development rates remained stable at an average of 3,027m per month in 1Q24(
4Q23: 3,038m per month).

Quarterly by-product gold production increased 20.8% and 12.5% vs. 4Q23 and 1Q23,
respectively driven by the higher ore grade and increased recovery rate.

Silver ore grade in 2024 has been reviewed and is expected to be in the range of
160 to 180 g/t, while the gold ore grade is estimated to be between 0.60 to 0.70
g/t.

**SAUCITO MINE PRODUCTION**

| Lead (%) | 1.00 | 1.27 | (21.3) | 1.07 | (6.5) | 
| Zinc (%) | 1.52 | 2.29 | (33.6) | 1.68 | (9.5) |

Quarterly silver production decreased 4.9% vs. 4Q23 mainly driven by the lower ore
grade which resulted from: i) additional ground support required in some areas with
higher silver ore grade, and ii) a slight increase in dilution, primarily in stopes
mined through the long hole drilling method. Both factors were addressed in early
March by increasing ground support and adjusting the drilling and blasting patterns,
which will improve the silver grade going forward.

Quarterly silver production increased 15.3% vs. 1Q23 primarily due to the higher
volume of ore processed as a result of the improved productivity and increased equipment
availability. This more than compensated for the lower ore grade driven by the previously
mentioned factors.

Quarterly by-product gold production increased 12.1% vs. 4Q23 mainly driven by the
higher ore grade.

Quarterly by-product gold production decreased 9.5% vs. 1Q23 driven by the lower
ore grade as a result of higher dilution and to a lesser extent lower recovery rate,
partly mitigated by the higher volumes of ore processed due to previously mentioned
factors.

Mine development rates remained stable quarter on quarter at 2,840m per month in
1Q24 (4Q23: 2,810m per month), in accordance with the plan.

The silver ore grade for 2024 is expected to be in the range of 200-220 g/t, while
the gold grade is estimated to be between 1.10-1.30 g/t.

| Zinc (%) | 0.59 | 0.47 | 25.5 | 0.77 | (23.4) |

Quarterly gold production increased 16.3% vs. 4Q23 mainly due to the higher ore 
grade from the Virginia stope. This was partly offset by the lower volume of ore
processed due to power outages in March.

Quarterly gold and silver production increased 14.9% and 22.6% vs. 1Q23 respectively,
due to the increased volume of ore processed as a result of the timely preparation
of stopes at the Taspana and Veta Nueva areas, and the higher ore grade from new
stopes at the Jessica, Gota and Gotita areas.

Quarterly silver production slightly decreased vs. 4Q23 driven by the lower volume
of ore processed as mentioned above, partly offset by the higher ore grade.

The gold and silver ore grades for 2024 are estimated to be in the ranges of 1.1-
1.3 g/t and 160-180 g/t respectively.

**SAN JULIÁN VEINS**

Quarterly silver production increased 18.6% vs. 4Q23 and 55.4% vs. 1Q23, mainly 
due to the higher ore grade at San Antonio, La Dura and Eliza veins and increased
volumes of development ore with high ore grade.

Quarterly gold production increased 18.3% vs. 4Q23 mainly driven by the higher ore
grade due to the aforementioned factors.

Quarterly gold production increased 7.5% vs. 1Q23 mainly due to the higher ore grade
and, to a lesser extent, the increased volume of ore processed driven by the optimisation
of the maintenance programme.

We expect the 2024 silver and gold ore grades to be in the ranges of 160-180 g/t
and 1.00-1.20 g/t, respectively.

**SAN JULIÁN DISSEMINATED ORE BODY (DOB)**

Quarterly silver production decreased vs. 4Q23 and 1Q23 mainly as a result of lower
ore grade in the periphery of the ore body and the decrease in volumes of ore processed
as the mine approaches the end of its life.

The mine plan of the disseminated ore body was reviewed due to ground instability
in some of the remaining production areas. As a result, some changes to the mine
plan have been made, which will have an impact on the average silver ore grade for
2024, which is now expected to be around 70g/t. Mining activities are expected to
conclude in 3Q24. The impact on production at San Julián DOB has been partly offset
by a better performance in San Julián Veins, as previously described.-

| Silver (g/t) | 1.32 | 1.69 | (21.9) | 1.72 | (23.3) |

Quarterly gold production decreased 16.5% vs. 4Q23 mainly driven by the lower ore
grade, in accordance with the mine plan. This was partly offset by the increase 
in volume of ore processed driven by better performance at the dynamic leaching 
plants in 1Q24, which had been impacted by the previously reported electrical fault
in the third and fourth quarters of 2023.

Quarterly gold production decreased 26.9% vs. 1Q23 primarily due to the lower volume
of ore processed as a result of heavy rain in March, which required additional pumping
at the bottom of the pit, and consequently disrupted mining activities. Additionally,
the lower ore grade also contributed to the decreased gold production.

The gold ore grade in 2024 is expected to be in the range of 0.60-0.70 g/t.

**NOCHE BUENA**

4,144 ounces of gold were recovered from the leaching pads at Noche Buena during
the quarter. As previously reported, mining activities concluded in May 2023, and
the closure plan is ongoing at this mine.

plant and ore processed at the Fresnillo and Saucito beneficiation plants.

Attributable quarterly silver production decreased vs. 4Q23 primarily driven by 
the lower volume of ore processed due to a minor maintenance stoppage of four days,
originally planned for two, in March. This was partly offset by the higher ore grade
and increased recovery rates.

Attributable quarterly silver and gold production increased significantly vs. 1Q23
as commissioning of the flotation plant concluded in 1Q23.

Attributable quarterly gold production decreased 6.3% vs. 4Q23 mainly due to the
lower volume of ore processed.

The silver ore grade for 2024 is expected to be in the range of 380-420 g/t.

**SILVERSTREAM**

Quarterly silverstream production decreased 35.1% and 51.6% vs. 4Q23 and 1Q23 mainly
due to the decrease in volumes of ore processed driven by a technical stoppage of
the flotation plant, and a lower ore grade. The maintenance programme was concluded
in April.

Silver production in 2024 is estimated to be in the range of 2.5-3.0 moz.
