Revival provided final results from the 2025 drilling program at the Mercur Gold Project in Utah.
Details

  • Several notable intercepts at South Mercur, including:
    o RMC25-031: 74.3m @ 2.75 g/t (at 91m downhole), including 12.5m @ 8.04 g/t (at 130m downhole)
    o RMC25-032: 83.9m @ 1.09 g/t (at 14m downhole)
    o RMC25-033: 82.5m @ 0.96 g/t (at 13m downhole)
  • Drilling also encountered mineralized waste rock from the historical in-pit backfill, which is currently considered waste that would
    need to be moved. This suggests some waste-to-ore conversion, lowering the overall project strip ratio. Notable intercepts include:
    o RM25-171: 38.1m @ 0.49 g/t (starting at surface)
    o RM25-172: 16.8m @ 0.39 g/t (starting at surface)
    Conclusion
  • Positive. The Mercur deposit is generally low grade (overall average grade of ore used in PEA study is 0.60 g/t), but there are
    higher-grade domains within the deposit. Mercur is a Carlin-style gold system, and these are known to generate high-grade ore
    shoots that have historically been a significant value driver for many of the gold mines in Nevada. Hole 31 of today’s press release
    (12m @ 8 g/t) is showing intact high-grade zones at South Mercur.
  • We do temper this high-grade result with the observation that the intercept had a low cyanide soluble/fire assay (AuCN/AuFA)
    ratio of 52%, suggesting this mineralization is at least partially refractory (and would likely have low to marginal recoveries on a
    heap leach). But even low recoveries of high-grade mineralization can be economic, particularly when the grade is more than an
    order-of-magnitude better than the average reserve grade.
  • Such high-grade shoots will not only benefit the current heap leach project but also point to longer-term exploration potential on
    Mercur’s large 7,200-ha property. Recall that Revival recently exercised the option to acquire a 100% interest in the Mercur
    property.
  • The high-grade intercepts are important, but the project is low grade (sub-1g/t) on average, so it is important to put the entire 2025
    drill campaign into context:
    o The weighted average 2025 Mercur intercept grade was 0.77 g/t gold (>25% above the average mineral resource grade).
    o The weighted average 2025 intercept cyanide soluble/fire assay ratio was 77% (comfortably within the range of the 75%
    recovery assumed in the PEA).
  • Data collected from drilling in 2025 and 2026 will support the company’s planned PFS targeted for release in Q1/27, a major
    milestone on the path to restarting gold production at Mercur. Revival Gold is currently mobilizing to restart exploration and
    engineering drilling at Mercur later this month with a planned program totaling 16,000m.
