North Bay Resources Delivers Gold Shipment and Optimizes Production

Exciting Advancements at North Bay Resources
North Bay Resources, Inc. (OTC: NBRI) is thrilled to share the successful delivery of 344 pounds of gold concentrate to its refinery partner, Just Refiners, located in Reno, Nevada. This shipment is part of efforts stemming from the Company’s Fran Gold Project, where ore has been processed at the Bishop Gold Mill. The concentrate derived from this effort represents approximately 15 tons of gross ore processed, showcasing North Bay's commitment to efficient and effective mining operations.
Recent Improvements and Repairs
As part of its ongoing commitment to optimizing production, North Bay has implemented necessary repairs to the Raker/Classifier and changed out the balls in the ball mill. These updates are aimed at producing a finer grind targeting minus 150 mesh, an optimal particle size for recovery processes. The concentrate generated from the gravity-only circuit is now under close observation, as the flotation circuit undergoes refinement and testing.
Enhancements in the Flotation Circuit
The Company is dedicated to testing and perfecting the flotation circuit at the Bishop Gold Mill. Recent evaluations of the Clarkson-Feeders — which titrate the five reagents essential to the flotation process — have been completed, marking an important step towards boosting efficiency. Currently, the strategy for the staged implementation of reagents, along with conditioning and residence time, is being refined based on previous metallurgy assessments and the equipment at hand.
Optimization Strategies
The flotation chemistry involves a series of elements: conditioner, gold promoter, sulphide promoter, activator, and frother. The team at North Bay is determining whether better results could be achieved through a staggered addition of these components, starting with the conditioner and promoters, followed by the activator and frother, or if a combined approach in the existing conditioning tank would be more effective. Previous designs utilized various entry points for initial reagents, but modifications in procedure now necessitate all reagents to be introduced post-gravity recovery, refining the overall process. A decision regarding the use of a single or dual conditioning tank is expected shortly, paving the way for full-scale implementation of the optimized flotation circuit.
Updates on the Fran Gold Project
The Fran Gold Project continues to advance, as data re-compilation from the 104 drill holes is actively ongoing. With the addition of Leapfrog 3D modeling and resource estimation software, including innovative pit-shell designs, the project is set for an updated resource estimation. Notably, a recent discovery of a bulk tonnage gold deposit, featuring 149 meters of gold that averages 0.9 grams per tonne, has intensified the focus on re-evaluating the Fran deposit.
Exploration and Development Insights
Past efforts at the Fran Gold site, encompassing over 18,000 meters of diamond drilling, have revealed substantial intercepts of mixed vein and disseminated gold. The identified deposit area spans more than 1000 meters in length, 100 meters in width, and descends up to 300 meters, with a known strike length of around 1700 meters. The Fran Gold Project's proximity to key mines, including Centerra Gold’s Mt. Milligan Project and Artemis Gold’s Blackwater Mine, solidifies its strategic significance. Both sites represent some of the largest new copper and gold mining operations in North America, further highlighting the potential of the Fran project.
In conclusion, North Bay Resources is not only progressing with its current projects but also meticulously planning for the future. With ongoing advancements in production techniques and resource estimation technologies, the Company is positioning itself for long-term success in the mining sector.
