GRavity survey initiated, high-resolution airborne magnetic

and radiometric survey to follow

  

Tonopah, Nevada / September 16, 2025 – TheNewswire - A2Gold Corp. (“A2Gold” or the “Company”) (AUAU: TSX-V) (AUXXF: OTCQX) is pleased to announce that it has commenced a comprehensive two-phase geophysical program at its highly prospective, flagship Eastside Gold-Silver Project in the Walker Lane Gold trend near the town of Tonopah, NV.  Less than 18% of the 92 km2 project area has been explored to date.  This program is designed to significantly advance the Company’s understanding of the property-scale geologic framework and to refine drill targeting ahead of a major upcoming 18,000-metre reverse circulation (RC) drill campaign.  As recently announced, a 2,000-metre diamond core drill program is already underway at the McIntosh zone testing a significant high-grade discovery in that area.

 

The 2025 Geophysical Exploration Program will extend through to the end of September and will consist of multiple surveys designed to provide both property-scale and zone-specific insights.

 

Peter Gianulis, CEO, commented, "The scale of this geophysics program underscores our commitment to systematically unlocking the district-scale potential at Eastside. With the gravity survey underway and the airborne magnetic and radiometric survey set to begin, we are building a comprehensive exploration model to guide the next phase of drilling. We believe these surveys will be instrumental in identifying new targets and expanding zones of mineralization, setting the stage for the most aggressive drill program in A2Gold’s history.”

 

PROGRAM OBJECTIVES

The two-fold objectives of the geophysical program are:

1. Identify exploration and expansion targets to support A2Gold’s fully funded 18,000-metre RC drill program, scheduled to commence later this year. 

2. Enhance the evolving property-wide exploration model while integrating structural, lithological, and geophysical datasets to better understand the distribution of mineralization. 

 

GRAVITY SURVEY

The Company has commenced a ground gravity survey at Eastside utilizing 800 stations on a 300-metre grid across the claim block. The survey, conducted by Zonge International Inc. of Reno, Nevada, is designed to map pre-Tertiary basement structures that may have controlled volcanic dome emplacement and associated mineralization.

 

AIRBORNE MAGNETIC AND RADIOMETRIC SURVEY

The next phase of the program will consist of a high-resolution helicopter-borne magnetic and radiometric survey to be conducted by Precision GeoSurveys. This survey is scheduled to commence this month.

• Survey Parameters: flown at a nominal flight height of 35-metres above ground using a nose stinger magnetic sensor configuration 

• Coverage: approximately 66.9 km² at 50-metre line spacings, for a total of 1,469 line-km of data 

• Objective: extend coverage southward from a previous drone magnetic survey that successfully defined structural and alteration trends within the volcanic rocks 

 

Results from both surveys are expected within 1–2 months and will directly guide the selection and prioritization of drill targets across Eastside, including the McIntosh and Castle Zones.

ABOUT EASTSIDE

The Eastside Gold-Silver Project is located in Esmeralda County, Nevada, approximately 20+ miles northwest of Tonopah, within the prolific Walker Lane Trend. The project hosts a current inferred resource of 1.4 million ounces of gold and 8.8 million ounces of silver, with mineralization open in all directions. Eastside covers a 92 km² land package that includes multiple high-priority zones such as McIntosh, Castle, and other exploration targets yet to be named.

  

ABOUT A2GOLD CORP

A2Gold Corp. owns three highly prospective gold projects in the United States all of which are in the mining-friendly jurisdiction of Nevada. A2Gold’s flagship, district-scale Eastside Gold-Silver Project hosts a large and expanding gold and silver resource and is in an area of excellent infrastructure. Preliminary metallurgical testing indicates that both oxide and sulphide gold mineralization at Eastside is amenable to heap leaching.
