TVZ Zone

On April 23, 2026, Discovery Silver Corp. (“Discovery”) announced drilling at the TVZ project included 17 holes for 5,803 m to confirm and expand the TVZ Zone. Results from the program were positive and included multiple significant assays from the TVZ1 and TVZ2 zones, which mark the north and south limits of the zone. Discovery stated that drilling at TVZ is ongoing with two drills operating on the 1210 level and one drill on the 1410 level. Drilling on the 1210 level is primarily focused on infilling and extending mineralization proximal to historic drilling, while drilling on the 1410 level continues to test the projected down plunge extension of the TVZ Zone. The current work program is designed to infill and expand the TVZ Zone, with drilling ongoing from historic drill platforms, in preparation for an initial NI 43-101 mineral resource in late 2026. Metalla holds a 2.0% NSR royalty on the TVZ Zone.
