3rd Party Processing Adds over 40,000 ounces AgEq*

Vancouver, British Columbia – Guanajuato Silver Company Ltd. (TSX-V:GSVR) (OTCQX:GSVRF) is pleased to provide a production update for the month of January 2024. Production results are generated from the Company’s wholly owned El Cubo Mines Complex, Valenciana Mines Complex, and San Ignacio Mine in Guanajuato, Mexico, the Topia Mine in Durango, Mexico, and the El Horcon Mine located in Jalisco, Mexico.

January 2024 Operations Highlights

• Production during the month of 329,934 silver-equivalent ounces is the 2^ND highest level of production in the Company’s history, and is derived from 141,854 ounces of silver; 1,843 ounces of gold; 279,726 pounds of lead; and 269,276 pounds of zinc. Guanajuato Silver is primarily a precious metals producer; over 90% of silver-equivalent production for the month was derived from silver and gold.
• First month of recently announced 3^rd party processing agreement adds 40,862 AgEq* ounces, this represented 12% of total consolidated production for the month. (See Guanajuato Silver news release dated January 17^th – “Guanajuato Silver Commences Processing 3^rd Party Gold and Silver at El Cubo“).
• Total tonnes mined in January over December increased by 32% to total 56,691 tonnes. Guanajuato Silver processes mineralized material at three production facilities: El Cubo, Cata (VMC), and Topia.
• Horcon generated 10,183 AgEq* ounces for the month; to date, the El Horcon mine has produced over 37,000 AgEq* ounces since processing of stockpiled material commenced in late 2023, (See GSilver news release dated November 7, 2023 – “Guanajuato Silver Initiates Processing of Mineralized Material from El Horcon Mine”). Additional stockpiles exist in the immediate El Horcon area; moreover, the processing of mineralized material from El Horcon is providing valuable information for understanding the potential for underground mining operations.
• Dewatering of the Villalpando area of El Cubo is opening up new zones of deeper, higher-grade material; mining teams are already working in new areas of the mine that have recently become accessible. By April, dewatering of additional sections of Villalpando is projected to open-up mining blocks that have demonstrated historical grades of over 350g/t AgEq**.
• At Topia, changes to the business model are proving successful; the adding of additional mine contractors is currently underway and is expected to increase current production volumes by up to 20%. For the month of January, Topia produced 85,083 AgEq* ounces.

James Anderson, Chairman and CEO, said, “The processing of 3^rd party mineralized material is already having a substantial impact on total production output; furthermore, El Horcon is generating consistent results and was responsible for over 3% of total AgEq production for the month. These two sources of mineralized material represent a significant component of total production and have contributed to generate our highest volume of silver-equivalent production since May 2023. January’s results are further confirmation that the adjustments and efficiency upgrades implemented at our mines during the later-half of 2023 have us on-track in terms of quarter-over-quarter increases in precious metals production. In addition to maintaining a steady ramp-up at our three production facilities, we will continue to make the securing of additional 3^rd party processing agreements a focus for 2024.”

*Silver equivalents (AgEq) are calculated using an 89.51:1 (Ag/Au), 0.04:1 (Ag/Pb) and 0.05:1 (Ag/Zn) ratio.
** Historical silver equivalents calculated using 80:1 (Ag/Au).
