Vancouver, British Columbia--(Newsfile Corp. - August 20, 2026) - Pacifica Silver Corp. (CSE: PSIL) (OTCQB: PAGFF) ("Pacifica Silver" or the "Company") is pleased to announce that it has received permits for 491 additional drill pad sites at its 100%-owned Claudia Silver-Gold Project in the historic El Papantón Mining District, Durango State, Mexico. The permits, issued by SEMARNAT (the Mexican Ministry of Environment and Natural Resources), significantly enhance the Company's operational flexibility by improving surface access to multiple existing and new priority drill targets. The Company is now expanding its ongoing Phase II drill program to 30,000 metres and mobilizing a fourth diamond drill rig to site by the end of August 2026.

"Securing 491 new permitted drill pads represents a major operational milestone for Pacifica Silver and greatly expands our ability to advance resource-definition drilling," stated Todd Anthony, Chief Executive Officer of Pacifica Silver. "The newly permitted sites will provide us with improved access to existing high-priority target areas at the northern extensions of the Aguilareña and Guadalupana veins, as well as the HL vein and Santiaguera vein targets in the eastern portion of the project area."

"The imminent arrival of a fourth rig will allow us to intensify drilling on the northern Aguilareña extension, where we have already identified a robust mineralized ore shoot. We look forward to generating additional data quickly in this highly prospective area as we work towards establishing a maiden resource estimate at Claudia in 2027," concluded Mr. Anthony.

About Pacifica Silver Corp.

Pacifica Silver Corp. is a Canadian resource company led by a proven management team with decades of mining and exploration experience in Mexico. The company is focused on its 100% owned Claudia Silver-Gold Project located in Durango, Mexico. Spanning 11,876 hectares, the Project encompasses most of the historic El Papantón Mining District where at least nine small mines operated intermittently during the 20th century. Since 1990, sampling and drilling within the Project have returned high-grade silver and gold intercepts across multiple vein systems, with only 10% of over 30 kilometres of known veins having been drilled. Today, the project is a prime target for modern exploration and holds exceptional potential for new high-grade discoveries.
