Magna Terra Partner Lunex Metals Advances Exploration and Reports Results from Initial Drill Program at the Luna Roja Project in Santa Cruz, Argentina

About this update from Magna Terra Minerals Inc

Toronto, Ontario--(Newsfile Corp. - July 15, 2026) - Magna Terra Minerals Inc .  (TSXV: MTT)  (the " Company " or " Magna Terra ") is pleased to announce that partner Lunex Metals Corp. (" Lunex ") has released assay results from a recently completed diamond drilling program at the Company's Luna Roja Project ("Luna Roja" or the "Project") in Santa Cruz Province, Argentina (Figure 1) . The drill program, comprising sixteen diamond drill holes (LR_DDH09 to LR_DDH19 and LR_DDH23 to LR_DDH27) totaling 2,517.5 metres, was designed to test multiple targets, including the Cruz del Sur, Orion, and Estrella del Norte targets, along the Vía Láctea structural corridor, a major northwest-trending structure approximately 2.8 kilometres in length (Figure 2; Table 1) . These results were originally reported in Lunex news releases dated July 2 and July 8, 2026, and are summarized below, in Table 2 and Figure 3 . "We are very pleased with the work to date undertaken by the Lunex team at Luna Roja. This successful initial drill program follows up on and significantly enhances the drill success we had on the Project in 2019. The Lunex drilling campaign focused on the 2.8 km-long Vía Láctea mineralized corridor and continues to demonstrate the presence of a potentially significant epithermal system. What is most encouraging is the presence of significant widths of near surface precious metals (Au / Ag) mineralization reported in almost every hole, confirming potential strike length and identifying new zones of mineralization. While still early days, this preliminary drill program confirms that there is a potentially significant epithermal gold system present at Luna Roja, and we look very forward to Lunex's continued work 'unlocking' this potential." ~ Lew Lawrick, President and CEO, Magna Terra Minerals Inc. "We are very encouraged by the initial results from Luna Roja. The reported drill holes intersected broad zones of hydrothermal alteration, silicification, brecciation, sulphide mineralization and quartz stockwork veining along the Vía Láctea structural corridor, confirming the presence of a large-scale epithermal system. Importantly, the results obtained to date suggest that gold and silver mineralization at Cruz del Sur remains open both toward the north and at depth. This supports our interpretation that the Vía Láctea corridor is not an isolated occurrence, but a broader mineralized system with significant expansion potential. The Estrella del Norte results are particularly encouraging as they confirm the presence of a new mineralized center located more than two kilometres north of Cruz del Sur. Drilling identified mineralized intervals associated with silicification, hydrothermal alteration and structures related to the Vía Láctea corridor, demonstrating that the system extends beyond the area initially defined.
