Allegiant Receives BLM Approval for Exploration at Castle Zone Within Eastside Gold Project Plan of Operation Significantly Expands the Project Area

(TheNewswire)

Tonopah, Nevada August 20, 2025 TheNewswire - Allegiant Gold Ltd. ("Allegiant" or the "Company") (AUAU: TSX-V) (AUXXF: OTCQX) is pleased to announce that it has received formal approval from the Bureau of Land Management (BLM) and the Nevada Division of Environmental Protection (NDEP) for its Environmental Assessment (EA) and Plan of Operations for the Castle Project, located in Esmeralda County, Nevada, approximately 22 miles west of Tonopah.

The approval allows Allegiant to proceed with an extensive multi-year exploration program, including up to 50 acres of surface disturbance, multiple drill phases, and the ability to construct roads, drill pads, sumps, staging areas, and conduct trenching over a highly prospective gold-bearing area; leading to more comprehensive large-scale exploration.

CASTLE PROJECT PLAN HIGHLIGHTS:

  • Approved for up to 145 drill pads in Phase I, with flexibility for additional drilling phases

  • Up to 50 acres of permitted disturbance within a 1,658-acre project boundary

  • Located adjacent to the historic Boss Mine, Castle has an inferred resource of 314,000 ounces of gold

  • Significant infrastructure advantages with direct highway access via US Routes 6 and 95

Peter Gianulis, CEO of Allegiant Gold , commented: ""The approval of the Castle Plan of Operations is a significant milestone for Allegiant. This permit provides the scale and flexibility we need to aggressively test a large and highly prospective gold system at Eastside and in the heart of Nevada's Walker Lane trend. We believe the Castle Project has the potential to deliver new discoveries at Eastside and grow into a substantial exploration asset, especially given its proximity to historic production, favorable logistics, and extensive past data."

1 The updated resource estimate ("Updated Resource Estimate and NI 43-101 Technical Report, Eastside and Castle Gold-Silver Project Technical Report, Esmeralda County, Nevada") conducted by Mine Development Associates ("MDA") of Reno, Nevada, with an effective date of July 30, 2021, contained a pit-constrained Inferred Resources (cut-off grade of 0.15 g/t Au) of  61,730,000 tonnes grading 0.55 g/t Au and  4.4 g/t Ag at the Original Pit Zone (1,090,000 ounces gold and 8,700,000 ounces silver) and  19,986,000 tonnes grading 0.49 g/t Au at the Castle Area (314,000 ounces gold).
