• • 6.1 meters at 739.58 g/t Ag and nil.21 g/t Au (8.79 g/t AuEq)

Alex Davidson, Vice President, Exploration commented: “I’m very excited to announce the primary result of the 2025-2026 Exploration Drill Program designed to apply up at the successes of the 2024 drill program at each Brimstone and Vortex.  The intercepts in Hollow H25D-6070 are very vital as this represents the perfect silver grades with the longest steady intercept we’ve visible in Vortex to this point.  This intercept extends high-grade mineralization ill dip to the west roughly 75 meters from the farthest hollow drilled within the 2024 program and spread out grounds of alternative to the north and south that these days haven’t any drilling.  The primary hollow finished this presen was once H25D-6068 and was once drilled 200 meters east of H25D-6070.  It was once designed to check the footwall of the Albert fault intersection of the high-grade silver development. Day the effects didn’t go back the grade of mineralization we generally see in Vortex, there’s robust mineralization over 169 meters that signifies we’re nonetheless inside an excessively notable mineralized zone, requiring additional exploration on this a part of the warehouse.  See backup main points under.

Drilling at Brimstone and Vortex

Drilling is definitely underway at the high-grade silver methods at each Brimstone and Vortex. The stream drill program started at Vortex occasion the Corporate was once finishing geophysics at Brimstone to refine drill goals.  To era, the Corporate has finished:

• 4 (4) holes totaling roughly 1,550 meters at Vortex
• Six (6) holes totaling roughly 3,320 meters at Brimstone
  • Together with two holes within the doable feeder device introduced on September 9, 2025.

Spare assays are starting to are available and the Corporate anticipates extra exploration drill ends up in the close time period.

The 2025-26 Exploration drill program has more than one goals:

• Top-grade Brimstone silver device:
  • Flow geometry is roughly 380 meters ill dip, by way of roughly 250 meters north to south, and roughly 30 meters in thickness
  • Silver to gold ratio is 3000:1
  • Checking out the down-dip and lateral extensions of Brimstone
  • Fresh geophysics at Brimstone recognized a possible feeder device and two (2) holes had been drilled in that device. Visually we’re sight mineralized veins within the goal section demonstrating we’re nonetheless noticeable at intensity. Assays for those holes are pending with effects anticipated very early within the brandnew presen.
  • Geophysics anomaly (doable feeder device) has really extensive collision area (more than 600 meters) which represents vital upside doable
• Top-grade Vortex silver device:
  • Flow geometry is roughly 1-kilometer downdip and roughly 500 meters east to west
  • Silver to gold ratio is 600:1
  • Checking out mineralized extensions ill plunge with a focal point round structural intersections and tendencies extending north, south and at intensity
• Manganese Goal (Brimstone highwall):
  • Observe-up on encouraging effects from 2024 which is a gold and silver oxide goal which may be significant in a re-start of a heap leach operation.

Directional Drilling is bettering potency and preserve prices

The Corporate may be using directional drilling at each Vortex and Brimstone.  TonaTec Exploration, LLC of Mapleton, Utah (“TonaTec”) is the operator on the second one core drill rig.  TonaTec has 40 years of mixed enjoy in directional drilling within the mining {industry}.  This era is being worn to get right of entry to more than one goals from a unmarried drill hollow at Hycroft.  This mode of drilling makes use of roughly 300 meters of drilling from floor for more than one holes.  Nearest the preliminary hollow is drilled to its goal intensity, the upcoming few holes wedge off the preliminary hollow at a intensity of roughly 300 meters and will get right of entry to backup goal grounds inside roughly 120 meters or extra.  This method will increase drilling potency by way of preserve hour because the preliminary 300 meters can tug as much as two weeks to drill, decreasing the collection of drill pads, with each advantages decreasing exploration prices.

Possible Heap Leach re-start

Because of the upper gold and silver value environments, the Corporate is comparing the possible to re-start a heap leaching operation in journey of the milling operation.  As a part of this research, the Corporate is carrying out a opposite circulate (RC) drill program to fill in gaps between recognized heap leach subject material within the Bay, Brimstone and Camel deposits.  Moreover, the Corporate plans to RC drill the Manganese goal close Brimstone which is a gold and silver oxide device and can be a significant contributor to a heap leach operation.  The research on a possible re-start of a heap leach operation will likely be finished within the first part of 2026.

Useful resource Replace and Technical Record

The Corporate will likely be updating its mineral useful resource estimate to incorporate the drilling finished in 2023 and 2024, which basically is composed of the 2 brandnew high-grade silver discoveries at each Brimstone and Vortex. This useful resource estimate will likely be finished early within the first quarter of 2026 and can incorporate a category to incorporate the heaps and grade of the high-grade silver methods at Brimstone and Vortex.  The up to date useful resource estimate will feed into the overall mine making plans for the technical document with economics which is now anticipated to be to be had overdue within the first quarter of 2026, following the useful resource estimate.

Force Oxidation (“POX”) metallurgical take a look at paintings has been finished and demonstrates that vital gold and silver healings may also be accomplished from Hycroft’s sulfide ore.  Those effects will likely be integrated within the brandnew mineral useful resource and technical document.

Hycroft continues to judge trade-off research for a hot procedure possibility which might grant a 3rd earnings current in the course of the derivative manufacturing and sale of sulfuric acid.  Ongoing hot take a look at paintings is considering figuring out optimum working parameters, together with temperature and retention instances, along with undertaking design and gear variety.   This take a look at paintings has been considerably slower than expected and is now anticipated to be finished in 2026. 

Stability Sheet

As of December 12, 2025, Hycroft had unrestricted money of roughly $175 million and extra debt sovereign.  On December 8, 2025, Hycroft’s regular book accomplished a VWAP of a minimum of $8.00 for 20-trading days out of 30-trading days, which permits the Corporate to present a required workout understand to the difference September 2, 2025, warrant holders.  The proceeds from the desired warrant workout will likely be $41.3 million along with the $0.7 million up to now gained from prior September 2, 2025, warrant workout routines.  The proceeds are anticipated to be gained in January 2026.
