Vancouver, British Columbia--(Newsfile Corp. - June 30, 2025) - ESGold Corp. (CSE: ESAU) (OTCQB: ESAUF) (FSE: Z7D) ("ESGold" or the "Company") is pleased to announce a significant expansion of its Montauban Project mine building to support the Company's transition into gold and silver production. Originally planned at approximately 2,000 square feet, the building is now being expanded to 4,000 square feet to accommodate enhanced operational needs and support infrastructure.

This latest development reflects the Company's continued momentum and preparation for a highly active construction and commissioning season at Montauban.

"As construction progresses and we prepare for near-term operations, we're not just building infrastructure—we're establishing the systems and capacity needed to support sustained production and long-term growth," said Paul Mastantuono, CEO of ESGold. "This expanded footprint reflects the pace of our momentum and the long-term vision we are committed to delivering at Montauban."

Expanded Capacity for Production Readiness

The enlarged facility will now include:

• Dedicated crew accommodations, including change rooms and showers to support on-site personnel
• Control rooms for monitoring the gravity separation and processing systems
• A secure lab space for ongoing gold and silver concentrate testing
• Expanded "Gold Room" storage for secure handling and safekeeping of gold and silver dore bars

The Company has also shipped railbed pre-concentrate samples for ongoing lab testing, with results expected in the near term. These results will guide final adjustments to the flow sheet and may impact future on-site processing efficiency.

What's Ahead for ESGold

• Preliminary Economic Assessment (PEA) - Imminent release of updated study outlining project economics
• Ambient Noise Tomography (ANT) Results - Final imaging and 3D model to be released shortly
• Exploration Strategy - Expansion beyond tailings into district-scale targets
