GUANAJUATO SILVER REPORTS BEST EVER QUARTERLY PRODUCTION

Guanajuato Silver Company Ltd. has released consolidated production results for the three months ended March 31, 2024. Production results are generated from the company's wholly owned El Cubo mines complex, Valenciana mines complex (VMC) and San Ignacio mine in Guanajuato, Mexico, the El Horcon mine in Jalisco, Mexico, and the Topia mine in Durango, Mexico.

Q1 2024 production highlights:

• Production during the quarter of 987,312 silver equivalent ounces (AgEq) is the best quarter in the company's history since production began at the company's El Cubo mines complex in Q4 2021; production is derived from 428,279 ounces of silver; 5,384 ounces of gold; 879,242 pounds of lead; and 922,927 pounds of zinc.
• Tonnes milled increased by 20.1 per cent over the previous quarter; a total of 165,079 tonnes were processed among Guanajuato Silver's three production facilities.
• Average silver and gold recoveries increased to 88.6 per cent and 89.2 per cent, respectively, as compared with 84.5-per-cent silver recovery and 88.8-per-cent gold recovery in fourth quarter 2023.

James Anderson, chairman and chief executive officer, said: "Q1 generated our best production performance to date and continues the trend of demonstrable quarter-over-quarter increases in precious metals production. In 2023, we made significant capex investments aimed at improving efficiencies across all of our producing assets; the impact from these improvements is now being realized as evidenced by our strong start to the year. We look forward to building upon our success as we continue to grow Guanajuato Silver into a prominent producer of silver and gold."

Q1 2024 production demonstrates significant improvements over previous quarter

Total tonnes milled was up 20.1 per cent over the previous quarter; the increase in total milled tonnage was partly due to the processing of mineralized material from the company's El Horcon mine and from the processing of third party gold and silver (See Guanajuato Silver news release dated Jan. 17, 2024 -- "Guanajuato Silver Commences Processing 3rd Party Gold and Silver at El Cubo"). During the quarter, 117,043 silver equivalent ounces were generated through the processing of third party mineralized material, and 59,914 silver equivalent ounces were generated from the processing of stockpiled material at Horcon.

Gold production of 5,384 ounces in Q1 denotes a 22.5-per-cent increase from the previous quarter; this increase was primarily the result of increased tonnage over the quarter coupled with strong gold recoveries of 89.2 per cent.

Silver production of 428,279 ounces in Q1 was an 8.4-per-cent increase from the previous quarter; silver production for the quarter generated 43.3 per cent of total AgEq production.

At Topia, lead production of 879,242 pounds in Q1 was up 5 per cent over the previous quarter; zinc production declined 4 per cent to 922,297 pounds. During Q1, 2024, Topia generated 288,579 silver equivalent ounces, which represented 29.2 per cent of total production. Topia is the only polymetallic mine within Guanajuato Silver's asset portfolio; all of the company's other mines are pure precious metals producers.
