FIRST QUARTER PRODUCTION REPORT

FOR THE THREE MONTHS ENDED 31 MARCH 2022

Octavio Alvídrez, Chief Executive Officer, said:

"We are reporting a solid first quarter's production, in line with expectations. We have taken proactive steps to manage the impact of the Mexico labour reforms, and though we continue to see some covid-related absenteeism at our mine sites, this declined during the quarter and we are currently seeing a limited covid impact. Like other industry sectors, the labour market remains very tight, and we have also seen some delays to equipment deliveries given the global supply constraints. That said, we remain committed to delivering on our targets for the year, completing the labour reform process, ramping up new Juanicipio production rapidly once connection to the electricity grid is enabled by mid-2022, capitalising on the considerable opportunities presented by our highly prospective exploration programme, while never losing focus on our people, their well-being and their safety. Our full year guidance is unchanged."

HIGHLIGHTS

Silver

Quarterly attributable silver production of 13.3 moz (including Silverstream), up 2.8% vs. 4Q21 mainly driven by a higher contribution of ore from Juanicipio and a higher volume of ore processed and ore grade at Fresnillo, partly offset by the anticipated lower volume of ore processed at Saucito.

Quarterly attributable silver production increased 5.1% vs. 1Q21 primarily due to a higher contribution of ore from Juanicipio, offset by the anticipated lower volume of ore processed at Saucito.

Gold

Quarterly attributable gold production of 149.8 koz, flat vs. 4Q21 mainly due to a lower volume of ore processed at Noche Buena and to a lesser extent, a lower volume of ore processed at Saucito and San Julian Veins, mitigated by a higher ore grade and recovery rate at Herradura.

Quarterly attributable gold production decreased 34.4% vs. 1Q21 primarily due to an expected lower volume of ore processed and ore grade at Herradura.

Silver Equivalent Basis[1]

Attributable silver equivalent ounces of 25.3 moz in 1Q22 (1Q21: 30.9 moz).

OPERATING ENVIRONMENT

As previously reported, the labour reform in Mexico which restricts subcontracting of labour came into effect from 1st September 2021 resulting in the requirement to internalise a high proportion of our contractor workforce. The actions we announced to address this short term challenge will continue, including recruitment campaigns, training and investment in new equipment. These initiatives are on-going and have been effective, and we expect to complete the staffing process in the Fresnillo District, San Julián and Ciénega in the third quarter of this year, while our open pit mines, which saw a lesser impact, are now fully staffed. However, challenges remain: in common with other industry sectors, the labour market remains very tight, with considerable competition for talent. We are also experiencing some delays to new equipment deliveries due to global supply bottlenecks.

COVID-19 UPDATE

As reported in 4Q21, a fourth wave of Covid-19 reached Mexico. We began to see the impact of this increase in terms of staff absenteeism due mainly to self-isolation at the end of last year and this accelerated throughout January and into February. Covid-related absenteeism has since dropped off in March. Though we remain alert to any future waves and have the protocols in place to manage this, we are currently seeing limited impact of the pandemic on our operations.

By-Products

•     Quarterly attributable by-product lead production increased 3.4% vs. 4Q21 due to a higher contribution of development ore from Juanicipio, partially offset by a lower ore grade at San Julián DOB.

•     Quarterly attributable by-product zinc production increased 3.6% vs. 4Q21 due to a higher contribution of development ore from Juanicipio and a higher ore grade and recovery rate at Saucito, offset by a lower ore grade at Fresnillo.

•     Quarterly attributable by-product lead and zinc production decreased 20.2% and 8.3% vs. 1Q21 respectively, driven primarily by lower ore grades and decreased volumes of ore processed at Saucito.

DEVELOPMENT PROJECTS

The construction of the Juanicipio plant was delivered on schedule during 4Q21. We remain focused on complying with the requirements from the state-owned electricity company and the energy regulator to complete the tie-in to the national power grid, expected in mid-2022.

Once the required permits have been granted, we expect to ramp up operations to 85%-90% capacity by the end of the year.

SAFETY PERFORMANCE

The safety and wellbeing of our people is our priority. Despite the sustained improvement in total and lost time injury frequency rates, we deeply regret to report a fatal incident in early 2022, as disclosed in our Preliminary announcement. The tragic loss of our colleague is unacceptable. We are firmly committed to eliminating all injuries, and especially fatalities. To this end, we have reviewed the progress of the High Potential Incident and Critical Risk Control programme. The Company is sharing the lessons learnt following every accident or high potential incident with our employees and contractors across all our operations. Management and the workforce are collaborating to identify, design, implement and verify on-site the critical controls to prevent fatal and serious injuries. We reviewed the approach and effectiveness of the "I Care, We Care" programme in fostering leadership, accountability, safety culture, risk-based management and engineering systems and lessons learnt.

2022 OUTLOOK

2022 guidance remains unchanged. Attributable silver production is expected to be in the range of 50.5 to 56.5 moz (including Silverstream) while attributable gold production is expected to be in the range of 600 to 650 koz.

MINING OPERATIONS

FRESNILLO MINE PRODUCTION

Quarterly silver production increased 13.5% vs. 4Q21 due to a higher volume of ore processed as a result of regaining access to some mining areas following the commissioning of the pumping station during the quarter. We also saw the positive impact of improved labour resource allocation and the expected higher ore grade.  

Quarterly silver production decreased 7.5% vs 1Q21 primarily due to a lower ore grade resulting from the impact of the labour reform in Mexico and operational challenges, as set out in prior quarters, restricted operational flexibility.

Mine development rates remained flat quarter-on-quarter at an average of 2,866m per month in 1Q22 (4Q21: 2,832m per month), primarily due to the covid-related absenteeism experienced in January. February and March saw development rates above 2,900m which gives us confidence that we can regain a rate of 2,900 to 3,100 m per month on average during 1H22, as previously targeted.

Following a field trial in a production zone, the tunnel boring machine (TBM) is being relocated back to a development area which has more advantageous geomechanical characteristics than those found in production areas. This relocation will occur over the course of the following quarter, and therefore we do not expect to see any contribution from the TBM towards the mine's development rate until the second half of the year.

Actions to address the impact of the labour reforms (in particular recruitment campaigns and training) are ongoing and we expect to complete that process in the third quarter.

Quarterly by-product gold production decreased 1.9% vs. 4Q21 driven by a lower ore grade, mitigated by a higher volume of ore processed.

Quarterly by-product gold production increased 1.3% vs. 1Q21 due to a higher recovery rate, offset by a lower ore grade.

The silver ore grade in 2022 is expected to remain in the range of 190-210 g/t, while the gold ore grade is expected to remain in the range of 0.55-0.70 g/t.

SAUCITO MINE PRODUCTION

Quarterly silver production decreased 8.4% vs. 4Q21 as a result of a lower volume of ore processed due to the aforementioned impact of the labour reforms and Covid-related absenteeism. As explained in the prior quarter, we expect some variability in the ore grade and reduced volumes of ore to be processed in 2022 driven by the need for additional development of the mine in order to recapture operational flexibility following high levels of localised seismicity.   

Quarterly silver production decreased 13.0% vs. 1Q21 for reasons described above, mitigated by a higher ore grade and recovery rate.

We have continued our recruitment and training campaigns at the mine with the target of gradually reducing the shortage of personnel and returning the mine to its potential capacity, once fully staffed. Through these actions, expected to take effect during the first three quarters of the year, we are targeting a return to an average development rate of more than 3,000 metres a month during 2022. However, as set out above, challenges remain. The labour market remains tight and we are also experiencing some delays to new equipment deliveries due to global supply bottlenecks.

Quarterly by-product gold production decreased 7.5% vs. 4Q21 mainly driven by a lower volume of ore processed.

Quarterly by-product gold production decreased 38.9% vs. 1Q21 due to a lower volume of ore processed and ore grade.

Full year 2022 silver ore grade is estimated to remain between 175-195 g/t, while the gold ore grade is estimated to continue to be around 1.10-1.20 g/t.

PYRITES PLANT (PHASE I)

Quarterly silver and gold production increased 24.6% and 12.2% vs. 4Q21 respectively due to higher ore grades from the Saucito flotation plant.

Quarterly silver production increased 9.9% vs. 1Q21 due to a higher ore grade from Saucito's flotation plant, and to a lesser extent, higher recovery rate, partially offset by a lower volume of pyrite concentrates processed from the Saucito flotation plant.

Quarterly gold production decreased 24.7% vs. 1Q21 due to a lower volume of pyrite concentrates processed.

In 2022, we continue to estimate silver production from the Pyrites plant at Saucito to be in the range of 700 to 750 koz while gold production is estimated to remain in the range of 1.5 to 2.5 koz.

As noted in previous reports, the Pyrites plant (phase II) was completed in 4Q20 but as with Juanicipio, we are focusing on complying with the new requirements from the state-owned electrical company and the energy regulator to complete the tie-in to the national power grid. We continue to expect this by mid-2022.

CIENEGA MINE PRODUCTION

Quarterly gold production decreased 5.7% vs. 4Q21 due to a lower volume of ore processed given the continued impact of the labour reform in Mexico and covid-related absenteeism.

Quarterly silver production increased 1.1% and 9.0% vs. 4Q21 and 1Q21 respectively due to a higher ore grade, partially offset by a lower volume of ore processed for the reasons explained above.

Quarterly gold production decreased 30.1% vs. 1Q21 due to the lower ore grades year-on-year, in line with the mine sequence and lower volumes of ore processed for the reasons explained above.

The gold and silver ore grades for 2022 are estimated to remain in the ranges of 1.20-1.40 g/t and 145-155 g/t respectively.

SAN JULIÁN MINE PRODUCTION

SAN JULIÁN VEINS

Quarterly gold and silver production decreased 10.7% and 11.7% vs. 4Q21 respectively due to a lower than expected ore grade following in-situ reconciliation with the geological model and a lower volume of ore processed driven by thinner veins.

Quarterly gold production decreased 15.5% vs. 1Q21 due to a lower ore grade as a result of depletion of the mine.

Quarterly silver production increased 9.8% vs. 1Q21 due to a higher ore grade, in line with the mining sequence.

We continue to expect the 2022 silver and gold ore grades to average 120-130 g/t and 1.35-1.55 g/t, respectively.

SAN JULIÁN DISSEMINATED ORE BODY (DOB)

Quarterly silver production decreased 6.8% vs. 4Q21 due to an expected lower ore grade as the mining sequence advanced towards the periphery of the ore body.

Quarterly silver production increased 4.7% vs. 1Q21 due to a higher volume of ore processed driven by the damage to the lead circuit housing in 1Q21 as previously reported adversely impacting the volumes of ore that could be processed at the time, partially offset by an expected lower ore grade.

We continue to expect the 2022 silver ore grade to be in the range of 150-170 g/t as we continue to advance towards the lower grade areas in the periphery of the ore body.

HERRADURA TOTAL MINE PRODUCTION

Quarterly gold production increased 12.2% vs. 4Q21 mainly due to an increased rate of solution flow following the short term disruption caused in the prior quarter due to the increased silt in solution restricting filtering capacity.

Quarterly gold production decreased 48.0% vs. 1Q21 due to a lower volume of ore processed in line with the mine plan as a result of larger haulage cycles and a lower ore grade in line with expectations.

The gold ore grade in 2022 is estimated to remain in the range of 0.65-0.75 g/t.

NOCHE BUENA TOTAL MINE PRODUCTION

Quarterly gold production decreased 23.5% vs. 4Q21 due to an expected lower volume of ore processed and ore grade. This was mitigated through the recovery of inventories at the pads.

Quarterly gold production increased 49.1% vs. 1Q21 due to a higher volume of ore deposited as a result of a lower stripping ratio, decreasing the waste material moved, in addition to a higher ore grade, partially offset by a lower recovery rate due to shorter irrigation cycles as a result of the ore being deposited in smaller areas as we approach the end of mine life.

The 2022 estimated gold ore grade remains in the range of 0.40-0.50 g/t, as the mine approaches the end of its operational life.

JUANICIPIO

Development and stope ore from Juanicipio continued to be processed in the Fresnillo and Saucito flotation plants. On an attributable basis, Juanicipio produced 1,344 koz of silver and 3,269 oz of gold in 1Q22.

As previously disclosed, the construction of the Juanicipio plant was delivered on schedule during 4Q21. We remain focused on complying with the requirements from the state-owned electricity company and the energy regulator to complete the tie-in to the national power grid. We continue to expect this in mid-2022.

Once the required permits have been granted, we expect to ramp up operations to 85%-90% capacity by the end of the year.

SILVERSTREAM

Quarterly Silverstream production increased 9.4% vs. 4Q21 due to a higher ore grade.

Quarterly Silverstream production decreased 6.0% vs. 1Q21 due to a lower volume of ore processed.

Silver production in 2022 is estimated to be in the range of 2.5-3.5 moz.
