<p>This concept paper discusses the application of blockchain technology and non-fungible tokens (NFTs) in the gold and precious metal mining industry. It emphasizes the importance of accurate mineral resource estimation in gold mining and how geostatistical methods and advanced interpolation techniques play a crucial role in this process. The document also explores the potential use and significance of blockchain technology and NFTs in certifying ownership of gold reserves and promoting transparency, traceability, and quality control throughout the gold mining value chain. The paper suggests that once gold mineral reserves are tokenized into NFTs through precise exploration, sampling, and mineral geostatistical analysis, gold reserves in-situ can be considered physical gold assets. This process involves allocating unique digital non-copy tags to individual units of gold reserves such as blocks within the mineral block-model. By linking these digital tags to the blockchain record, the gold value cycle can be traced from its mine location to extraction, then processing, to market. Blockchain technology and NFTs can be used to tokenize gold reserves, providing a transparent, secure, and traceable mechanism for certifying ownership. This approach enhances trust in ownership records increasing certainty in the gold market. The ability to certify ownership without requiring physical extraction of gold presents a significant opportunity to promote and embrace environmental practices, promoting environmental sustainability, significantly minimizing impact on local communities and the ecosystem.</p>
