rGO Gold

rGO Gold Recovery System

Exclusive Technology. Revolutionary Efficiency. Sustainable Gold.

Asia Broadband Inc. is redefining the future of precious-metal recovery through its exclusive acquisition and licensing rights to a revolutionary reduced graphene oxide (rGO) gold recovery system — a next-generation technology that blends nanoscience, clean chemistry, and scalable engineering to extract gold with unprecedented efficiency and minimal environmental impact.

The rGO system marks a transformative leap in AABB’s production capabilities, enabling the recovery of gold from ore, tailings, and complex leach solutions that conventional methods cannot efficiently process.

Exclusive Rights and Global Licensing

In July 2025, AABB completed a $23.5 million share-based acquisition of the rGO technology and now holds full exclusive rights to its application in gold recovery and extraction.
Under this agreement, AABB not only controls the proprietary process and intellectual property but also serves as the sole licensing authority worldwide — granting AABB the power to manage, distribute, and monetize rGO system deployments across the global mining industry.

This strategic position establishes AABB as both an operator and a technology licensor, opening new revenue streams through royalty-based partnerships, technology-sharing agreements, and joint ventures with other precious-metal producers.

How the rGO System Works

Leach Input
The system processes gold-bearing solutions — whether derived from traditional cyanide-free leaching, flotation concentrate, or tailings reclamation — feeding them through rGO contact membranes.
Selective Adsorption and Reduction
The rGO (reduced graphene oxide) substrate attracts and converts Au³? ions to metallic gold (Au?) through an electrochemical reduction on its surface.
This reaction is self-reducing and selective, favoring gold over base metals such as copper or iron.
Gold Deposition and Collection
Gold nanoparticles bond to the rGO surface, forming a visible metallic coating that can be mechanically separated or desorbed for refining.
Desorption and Regeneration
Using mild, non-toxic reagents, the deposited gold is released and refined into a pure product while the rGO substrate is regenerated and reused in subsequent cycles — maintaining efficiency over multiple runs.

Feature	Advantage
Exclusive Global Rights	AABB holds 100 % exclusive ownership and licensing control of the rGO technology.
High Recovery Rates	Proven recovery efficiency exceeding 95 % of gold ions, even from ultra-low-grade solutions.
Eco-Friendly Process	Operates without cyanide, mercury, or heavy chemical residues, minimizing environmental impact.
Tailings and Waste Recovery	Extracts residual gold from tailings and refractory ores once considered uneconomical.
Low Operating Costs	Minimal reagent consumption and reusable rGO membranes reduce cost per ounce.
Scalable Design	Modular 50-ton-per-day pilot units can expand to industrial-scale installations.
New Revenue Stream	AABB will license rGO systems globally, collecting royalties and technology-use fees.

Integration with AABB’s Processing Facilities

The rGO system will first be deployed at the Etzatlán Processing Plant as part of a 50 TPD pilot line in Phase 3 of the facility’s expansion.
This integration allows AABB to recover additional gold from both new production and historical tailings, significantly increasing total yield from existing operations.

Once validated at Etzatlán, the company will expand the rGO units to its other sites, including La Paz and Tequila, and pursue international licensing with third-party operators.

Strategic and Financial Impact

Enhances Profit Margins – Converts residual material into measurable revenue.
Licensing Revenue Potential – Exclusive global rights position AABB as a technology provider to the entire industry.
Strengthens ESG Profile – Supports sustainable mining through clean chemistry and waste reduction.
Long-Term Asset Value – The intellectual property and licensing rights form a perpetual intangible asset with growing royalty potential.

A New Era of Gold Recovery

The integration of rGO nanotechnology represents AABB’s transition from traditional miner to next-generation resource innovator — a company that not only extracts gold but also leads the innovation that defines how the industry evolves.

Through exclusive rights, scalable deployment, and sustainable efficiency, AABB’s rGO Gold Recovery System sets a new global standard for clean, intelligent, and profitable precious-metal production.
