Magma Silver Q3 Drilling Preparation Work Program

Vancouver, British Columbia--(Newsfile Corp. - July 30, 2025) - Magma Silver Corp. (TSXV: MGMA) (OTCQB: MAGMF) (FSE: BC21) (WKN: A411DV) (the "Company" or "Magma") is pleased to announce the commencement of a summer work program designed to evaluate and define targets for the planned Q4 drill program that will follow-up on previous work to identify new drill site locations at the advanced Niñobamba silver-gold project in Peru.

Stephen Barley, Chairman & CEO, stated, "We are excited to start a work program at the advanced Niñobamba silver-gold project focused on the Jorimina and Randypata deposits. As announced in our news release dated July 23, 2025, the Tunsulla community access agreement is in place for these two project areas, allowing the Company full access to conduct exploration activities. The work being carried out will assist in refining drill targets for our planned Q4 drill program as well as expand our overall knowledge of the deposits."

Q3 Work Program

The historical drilling by Newmont Corporation ("Newmont") on the Jorimina and Randypata deposits consisted of 3,536 rock samples, 2,988 channel samples, ground magnetics, and 4,377 meters (Jorimina) and 3,504 meters (Randypata) of drilling and assays. Results included: Hole JM1: 53.1 to 125.4 (72.3m) 1.19 g/t of gold and hole JM1: 184.75 to 209.35 (24.6 m) 1.07 g/t of gold. Results and discussion are provided in Newmont's internal report dated January 2010, "Informe Técnico y Geológic Proyecto Niñobamba Mayo - Diciembre 2009". (See news release dated July 23, 2025.)

The work conducted by Newmont mainly focused on gold. The historical drilling program conducted was widely spaced diamond drill holes. Management believes that Newmont's work should be followed up on as they may have missed significant mineralized silver and gold zones. Tighter drill space around JM-01 is required to better understand the nature and orientation of the mineralized zone. The work program will focus on refining drill targets and examine overlooked zones which contain surface silver-gold anomalies. As an example, the prospective Randypata silver zone exhibits a 2 km long silver anomaly that has never been drilled. The work program will be led by Senior Geologist, Edgar Leon (see news release dated July 16, 2025) and supervised by Jeffrey Reeder, P. Geo., Senior Technical Advisor.
