PL Gold Mine Restart Update High Grade Gold Results, Resource Expansion Potential and Operational Readiness Update

Toronto, Ontario--(Newsfile Corp. - July 29, 2026) - Minnova Corp. (TSXV: MCI) (OTC Pink: AGRDF) (" Minnova " or the " Company "), an advanced development-stage gold company focused on the restart and the expansion of our 100% owned PL Gold Mine in central Manitoba is pleased to provide an update on the restart of the PL Gold Mine. Resource Expansion and Infill Drilling Program Between September 2025 and April 2026, the Company completed its largest-ever infill drill program on the PL Gold Mine property, with more than 13,500 metres completed in 131 holes. The program focused on resource expansion and infill drilling to support an update to the current 2017 NI 43-101 Mineral Resource Estimate (2017 MRE). Results successfully demonstrated the deposit's resource expansion potential, with 18 holes targeting the PL North target area (PLN), interpreted as the on-strike extension of the main PL Deposit (PLD). PLN was discovered in 2017 through surface prospecting and sampling and was confirmed by subsequent drilling. Drilling completed at PLN between 2018 and 2026 is not included in the 2017 MRE. Results from PLN drilling are expected to be incorporated into the upcoming 2026 MRE. The target remains open along strike to the northwest and down dip, continuing to demonstrate further expansion potential. This press release highlights high-grade results above 5 g/t Au, which continue to demonstrate the resource expansion potential of the PL Gold Mine property. While high-grade mineralization is important and will be targeted in the early years of mining, lower-grade material is also expected to play a role in the updated 2026 MRE, particularly as it relates to the planned restart as an open-pit mine. The Company expects to provide an update on lower-grade results between 1.00 g/t Au and 4.99 g/t Au in subsequent releases. Highlights of 2025-2026 PLN area drill program include: Hole M-25-004 intersected PLN upper and lower mineralized structures returning 25 g/t over 0.50 m, 10.04 g/t over 1.4 m (see Table 1 below) Hole M-25-018 targeting the down dip extension of the PLN structure intersected 7.96 g/t over 1.5 m at down hole depth of 110.4 m extending the down dip projection of the PLN by over 300 m from surface, demonstrating continued resource and exploration potential of the PL property (see Figure 1). High grade mineralization was intercepted at shallow depths amenable to open-pit mining methods: M-25-011 - 8.23 g/t over 0.5 m from 6.75 m M-25-014 - 15.67 g/t over 1.4 m from 31.1 m M-25-016 - 7.92 g/t over 1.2m from 20.5 m The PLN target area remains open along strike and down dip, with future resource expansion drilling planned for fall and winter 2026. Near-surface gold mineralization at PLN supports its inclusion in planned large open-pit development. The balance of the drill program focused on infill and close-spaced drilling at the PLD to better define mineralized structures and achieve drill density appropriate for mine planning and scheduling ahead of initial open-pit mine development and future underground mining operations. Infill drilling focused on delineating sub-cropping mineralized structures that comprise the existing PLD 2017 MRE. An area of approximately 150,000 m 2 was targeted for infill drilling, with drill-hole spacing ranging from 50 m to 12.5 m and averaging approximately 21 m. This area of the PLD is targeted for future open-pit mine development. PLD infill drilling results confirmed strong grades at shallow depths across a strike length of approximately 500 m. Shallow intercept highlights include: Hole M-26-052 intersected 46.16 g/t over 1.50 m from 18.50 m Hole M-26-048 intersected 55.12 g/t over 1.00 m from 18.30 m Hole M-26-002 intersected 43.48 g/t over 1.50 m from 41.70 m Deeper high-grade intercepts confirm down dip extension of shallow mineralization and expansion of an area of very high-grade mineralization (see Figure 1). Highlights of deeper drill results (-50m to -200m) include: Hole M-25-020 inte...
