The approval incorporates around 100 acres into the existing SUP, increasing the permitted boundary to more than 1,300 acres.

Comstock Mining CEO Corrado De Gasperis said: "These land acquisitions border our planned mine expansions on the east side of the Lucerne mine, in close proximity to where current exploration and development drilling is ongoing and also along the northern borders of our existing heap leach operation, making future heap expansions more practical and efficient."

The company has received amendment to expand permitted uses for its Lucerne Resource Area, which is said to host the company’s classified gold and silver resources.

The amendment is applicable to surface and underground mining as well as processing and milling, mine definition, exploration, development and other ancillary activities.
