Correction to Press Release by Hycroft Mining

Hycroft Mining Holding Corporation (NASDAQ: HYMC), based in Winnemucca, Nevada, has announced a correction regarding a press release initially issued on April 21, 2026. The original release titled "Hycroft Engages Engineering Firm to Assess Underground Mining Options" contained inaccuracies related to the engineering firm responsible for certain key components of the project.

In the press release, it was mistakenly declared that WestLand Engineering Environmental Services, Inc. had completed the engineering work associated with the additional lifts on the tailings storage facility. However, the corrected information clarifies that the engineering work has been carried out by WSP Global Inc.. WestLand Engineering's role has been entirely focused on completing the pertinent environmental studies rather than the engineering tasks.

The completion of these engineering tasks is crucial as it allows Ausenco Engineering South USA, Inc. to finalize the Initial Assessment Technical Report with necessary economic considerations. Hycroft Mining expects this report to be completed within the second quarter of 2026, marking a significant step forward for the company's development plans.
