Hycroft is one of the largest gold and silver deposits in the world

With the current resource representing only 15% of our land position, there is significant opportunity to increase this world-class deposit as the mineralization remains open in all directions and at depth. In the past, there was no systematic exploration effort to understand the genesis of this unique asset, including exploring for potential feeder systems.

Notes

Mineral resources based on metal prices of $3,100/oz Au and $36.00/oz Ag.
Cutoffs are Income less Refining Cost, being NSR.
Gold equivalent for heap leach = cyanide gold + 0.0019 x total silver assay.
Gold equivalent for mill plus pressure oxidation = fire gold + 0.0107 x total silver assay.
Numbers may not sum exactly due to rounding.
Mineral resources are contained within a computer-generated optimised pit. Total material in that pit is 4.92 billion tonnes.
All units are metric. Ktonnes means 1,000 tonnes. Gold and silver grades are in grams per tonne.
Mineral resources are not mineral reserves, and detailed economic considerations have not been applied.
Modifying factors for mine and process design have not been applied.
