Lode Gold Resources Inc has announced the initiation of a new Mineral Resource Estimation block model for its flagship Fremont Gold Project in Mariposa, California. The work incorporates over 7,000 historical underground channel samples recently digitized from original mine maps, data previously unavailable in digital form. This significantly increases data density within the historically mined areas of the deposit.
The updated model will reinterpret the Fremont deposit as a continuous mineralized body rather than discrete vein-only domains. It will also evaluate the resource using a lower cut-off grade, supported by updated underground mining cost assumptions from local contractors. This approach aligns with the company's strategic focus on bulk underground mining, as outlined in recent technical and economic studies.
Jonathan Hill, Director and Chair of the Technical Committee, stated the new block model represents an important evolution in interpreting the Fremont deposit. By modeling the system as a continuous body and integrating the newly digitized samples, the geological model now better reflects the scale, continuity, and mining potential for a bulk underground approach.
The Fremont Gold Mine is an advanced exploration and early development brownfield project. Historical production halted in 1942 when gold mining was prohibited during World War II. The property has been a mine since 1849, one of the first projects of the California Gold Rush. It sits on the prolific 190 km Mother Lode Belt, with seven deposits along a 4km strike. Only two of these deposits have seen exploitation to date.
According to the company, only 8% of the mineral resource from the 2025 estimate has been exploited, leaving 92% to be mined in upcoming years. The project has substantial existing infrastructure, including 42,717.3 meters drilled, 8,593 underground channel samples, 23 kilometers of underground workings, and sits on 3,351 acres of patented private land with 100% ownership of surface and mineral rights. The site has road access, electricity, and proximity to rail and airport facilities.
The new Mineral Resource Estimation is being completed in accordance with NI 43-101 standards. Further updates, including results of the revised resource estimate, will be provided once the work is finalized and reviewed by Qualified Persons. Technical reports on the company's properties are available on the Company's profile on SEDAR+ and the Company's website at https://www.lode-gold.com.
For business and technology leaders monitoring the mining sector, this development represents a significant methodological shift with potential industry implications. The integration of historical data through digitization demonstrates how legacy assets can be re-evaluated with modern analytical techniques. The move toward bulk underground mining modeling could influence how other companies approach similar brownfield projects, potentially unlocking value from previously fragmented deposits.
The strategic focus on bulk mining at Fremont suggests a shift toward more efficient, large-scale operations that could improve project economics. This approach, combined with the site's existing infrastructure and private land ownership, may reduce both capital and operational risks compared to greenfield developments. The project's location in a stable mining jurisdiction like California adds to its appeal for investors seeking geopolitical security.
The updated resource model could have broader implications for gold supply, particularly if it demonstrates that historical mining districts contain more continuous mineralization than previously recognized. This might encourage similar re-evaluations of other legacy mining properties, potentially increasing global gold resources without requiring new discoveries. The technical approach being implemented at Fremont could serve as a model for revitalizing mature mining districts through advanced geological modeling and modern mining methods.
