Miami, FL – April 28, 2025 – NatGold Digital Ltd. (“NatGold” or the “Company”) is pleased to announce the filing of two additional provisional patent applications with the United States Patent and Trademark Office (USPTO), further strengthening its leadership position in the emerging digital gold mining industry.

With these latest filings, NatGold’s intellectual property portfolio now encompasses 11 provisional patent filings, covering the full lifecycle of digital gold mining—from resource verification and valuation to token issuance and trading. This milestone marks the completion of its IP development phase, establishing a robust foundation that safeguards its innovations across the digital gold ecosystem.

The first filing, the Digital Cutoff Grade (DCG) patent application, introduces a standardized methodology for evaluating unmined gold resources for digital tokenization. In traditional mining, a cutoff grade defines the minimum concentration of gold in a deposit considered economically extractable, based on fluctuating gold prices and production costs. This threshold determines how much of a deposit’s gold mineralization is officially classified as a resource, and it can shift dramatically as economic conditions change—introducing inconsistency into traditional resource reporting.

In contrast to traditional models, the DCG framework is designed for a system that permanently leaves gold in nature’s vault. It establishes three distinct approaches—Pure Digital, Hybrid Risk-Adjusted, and Conversion Methodologies—each ensuring that the geological certainty and risk-adjusted valuation of Certified NatGold Resources is standardized throughout the NatGold Token minting process.

The second filing applies DGC methodology within NatGold’s digital mining model, using Geological Confidence Factors (0.8 for Measured, 0.4 for Indicated, and 0.2 for Inferred resources) to determine appropriate resource discounting. Smart contracts encode these calculations into the blockchain, ensuring transparency and consistency. Hybrid models can further adjust for factors such as accessibility, geopolitical risks, and sustainability–creating a trustworthy resource valuation framework for investors.

Anthony Wile, Founder and CEO of NatGold Digital, commented, “Today’s filings mark the final critical step in the development of our patent portfolio. The introduction of a standardized Digital Cutoff Grade fundamentally differentiates NatGold’s digital mining process from traditional extraction models dependent on fluctuating economic conditions. By defining a consistent weight-value transfer system, we ensure that every NatGold Token minted is fungible, verifiable, and reliably backed by Certified NatGold Resources—regardless of where on the planet the gold is located.

“With 11 patents now pending, we have built a comprehensive, flexible intellectual property foundation that covers the entire NatGold ecosystem from end to end. We believe this positions NatGold Tokens as the ultimate safe haven digital asset—uniquely combining the intrinsic value of gold with the advantages of blockchain technology to offer a superior monetary alternative for the digital age.

“I would also like to thank Mark Stignani and the Barnes & Thornburg LLP legal team for their outstanding work and dedication throughout this critical phase. Their expertise has been instrumental in helping us build a truly formidable IP portfolio.”

NatGold’s expanding intellectual property portfolio covers critical innovations, including digital mining validation systems, blockchain-based token issuance platforms, resource authentication methods, dynamic cost analysis indices, and now, standardized digital cutoff grade frameworks.

As NatGold continues to build its global ecosystem, these patents serve to protect its leadership position while enabling a new, sustainable way to capture gold’s timeless value.

Anthony Wile further commented, “By completing this comprehensive intellectual property framework, NatGold Digital has created the foundation for NatGold Tokens to emerge as the ultimate digital store of wealth—combining gold’s intrinsic stability with the efficiency and transferability of blockchain technology.

“Unlike traditional gold-backed tokens or cryptocurrencies, NatGold Tokens provide a sustainably produced, non-dilutive, and fungible monetary alternative, uniquely positioned to meet the growing demand for sound money in the digital age.”
