Magma Silver begins summer work at Ninobamba

Mr. Stephen Barley reports MAGMA SILVER Q3 DRILLING PREPARATION WORK PROGRAM Magma Silver Corp. has commenced a summer work program designed to evaluate and define targets for the planned fourth quarter drill program that will follow up on previous work to identify new drill site locations at the advanced Ninobamba silver-gold project in Peru. Stephen Barley, chairman and chief executive officer, stated: "We are excited to start a work program at the advanced Ninobamba 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." Third quarter work program The historical drilling by Newmont Corp. on the Jorimina and Randypata deposits consisted of 3,536 rock samples, 2,988 channel samples, ground magnetics, and 4,377 metres (Jorimina) and 3,504 metres (Randypata) of drilling and assays. Results included: hole JM1: 53.1 to 125.4 metres (72.3 metres) of 1.19 grams per tonne of gold and hole JM1: 184.75 to 209.35 m (24.6 m) of 1.07 g/t of gold. Results and discussion are provided in Newmont's internal report dated January, 2010, "Informe Tecnico y Geologic Proyecto Ninobamba 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 it 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 two-kilometre-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, PGeo, senior technical adviser. Qualified person Jeffrey Reeder, PGeo, a qualified person as defined in National Instrument 43-101 and a senior technical adviser of the company, has prepared, supervised the preparation or approved of the scientific and technical disclosure contained in this news release. Coming marketing events Management will be attending the Precious Metals Summit in Beaver Creek on Sept. 9 to Sept. 12, 2025, and the Swiss Mining Institute Conference in Zurich on Nov. 20 and Nov. 21, 2025. Magma Silver will also be participating in 121 Mining Investment Conferences in London on Nov. 17 and Nov. 18, 2025, and in Dubai on Nov. 26 and Nov. 27, 2025. Investors can expect an update on the Q4 drill program at Ninobamba, Peru. The company invites the investment community to review its updated corporate presentation and fact sheet.
