North Bay Resources (OTC:NBRI) unveils internal estimate for the Bullion Alley Zone at Fran Gold Project
Resource modelling integrates multi-year drill data and identifies both bulk and high-grade zones
Project located adjacent to Centerra Gold (TSX:CG) and Artemis Gold (TSX:ARTG) developments
North Bay Resources (OTC:NBRI), an exploration company in the gold sector, has released a preliminary internal resource estimate for the Bullion Alley Zone at its Fran Gold Project. The announcement aligns with an increasingly active gold exploration landscape near large-scale operations including Centerra Gold’s (TSX:CG) Mt Milligan Project and Artemis Gold’s (TSX:ARTG) Blackwater Mine—both significant sites listed on Canadian indexes and influential within broader market benchmarks such as the ASX 200.
Preliminary Modelling of Bullion Alley Resource
Using Leapfrog Geo and Edge software, North Bay Resources modeled over a decade’s worth of diamond drilling, totaling extensive meterage across more than one hundred holes. The data compilation covers historic campaigns and incorporates recent additions. A block model has been developed to assess the extent of gold mineralization, with no cut-off applied at this stage.
The modelling has led to the recognition of a substantial bulk tonnage resource complemented by high-grade mineralization zones. These preliminary insights show mineral continuity and presence of gold-bearing material through core and disseminated structures, adding value to ongoing interpretation.
Drilling and Trenching Indicate Broader Mineralization
While historical exploration had primarily focused on narrow vein systems, the re-assessment has unveiled broader mineralized zones, particularly where trenching data shows consistently elevated surface grades. Recent trenching between the Main and East Zones, as well as to the north and east, has brought to light previously underappreciated disseminated mineralization zones.
The resource remains open in multiple directions and at depth, with historical drilling halted in areas where initial high-grade targets were not encountered. These zones now reveal signs of broader disseminated mineralization and increasing copper presence, signaling areas of further interest.
Dual-Focus Development Strategy in Place
The company is currently operating a dual-pronged strategy—processing high-grade surface material through its Bishop Gold Mill in California while concurrently evaluating the bulk tonnage deposit for long-term scale development. The Bishop facility is currently fed by oxide material sourced from surface stockpiles and trench-defined zones.
North Bay Resources' current focus extends to integrating trenching and sampling data from less-explored zones to support the development of a formal NI 43-101-compliant Mineral Resource Estimate. This data will be instrumental in delineating new targets for follow-up drilling and resource expansion.
Ongoing Efforts to Enhance Project Viability
In addition to exploration efforts, North Bay Resources has recently finalized the restructuring of a demand loan, converting a significant portion into a secured debenture and issuing long-term warrants. Work has also commenced with auditors to regain SEC reporting status, a step viewed as preparatory for a future uplisting.
With a property size exceeding several tens of thousands of acres and located near two of North America's most significant modern gold developments, the Fran Gold Project's latest estimates mark a pivotal step. The renewed interest in previously overlooked mineralization zones may contribute to broader sector developments, particularly in a market where ASX 200-listed peers and North American operations are seeing increased attention for scale and longevity.
