HYCROFT CONTINUES DRILLING HIGHER GRADES

Vortex Zone mineralization extends south

Brimstone Zone higher grades extend north

Gold and Silver identified in new area of Central Zone

WINNEMUCCA, Nev., Dec. 20, 2022 /PRNewswire/ -- Hycroft Mining Holding Corporation (Nasdaq: HYMC) ("Hycroft" or the "Company"), a gold and silver development company which owns the Hycroft Mine in the prolific mining region of Northern Nevada, is pleased to announce additional drill results from its 2022-2023 exploration program. 

Highlights from the recent drilling results in Table 1 are noted below. Reporting units are in grams per metric ton ("g/t"):

• H22R-5671 returned 35 meters of 2.83 g/t gold and 35.59 g/t silver
• Including 17 meters of 4.81 g/t gold and 48.53 g/t silver
  
  
  
• H22R-5671 also returned a separate intercept of 14 meters of 0.29 g/t gold and 102.92 g/t silver
  
  
  
• H22R-5670 returned 93 meters of 0.70 g/t gold and 55.94 g/t silver
• Including 29 meters of 1.57 g/t gold and 98.88 g/t silver
• Including 3 meters of 0.31 g/t gold and 163.5 g/t silver
  
  
  
• H22R-5684 returned 56 meters of 0.73 g/t gold and 19.32 g/t silver
• Including 18 meters of 1.07 g/t gold and 32.22 g/t silver

Alex Davidson, Vice President, Exploration commented, "The initial drilling campaign has focused on higher-grade opportunities primarily in the Brimstone, Vortex, and Central zones. All 20 RC drill holes reported to date have returned ore grade mineralization, of which 14 holes have outperformed the model resulting in higher grades than previously estimated or known. The results to date are very exciting as we established continuity between the higher-grade zones along structures. In addition, we continue to enhance the project economics through in-fill drilling that have demonstrated mineralization in areas previously considered to be waste." 

Hole H22R-5671 drilled in Brimstone returned very exciting results with multiple intercepts extending high-grade gold mineralization both north and up dip of the known high-grade zones. The high-grade silver Vortex zone continues to deliver positive results with Hole H22R-5670 returning two significant intercepts demonstrating mineralization continues south along the East Fault. 

Alex Davidson further stated, "Drilling in the Central zone is delivering ore grade mineralization where none was previously modeled.  The grades we are seeing in the Central zone are more than double the average resource grade and extends mineralization farther south than previously understood."

Diane R. Garrett, President & CEO commented, "We continue to be extremely pleased with the positive results from our exploration program. The second phase of the drill program will continue through the first half of 2023. Once permits are received, we will be stepping out beyond the known resource area and drilling prospective high-grade targets identified within our vast land position."

To date, the Company has successfully completed 24,000 meters of reverse circulation ("RC") drilling and 3,600 meters of core drilling in its 2022 drilling program. Additional results from the RC and core drilling program are expected in the first quarter of 2023. During November 2022, the Company began drilling targets in the Camel zone, just west of Vortex.

About the 2022-2023 exploration program
