North Bay Resources Announces Operation of New Gravity Circuit at Bishop Gold Mill, California
North Bay Resources (NBRI) has announced the successful installation and operation of new gravity separation and gold recovery equipment at its Bishop Gold Mill in California. The company is processing ore from its Fran Gold Project, with microscopic analysis showing significant gold recovery using a Knudsen Bowl concentrator.
Recent metallurgical studies from the Fran Gold Project demonstrated over 97% recovery rates, combining 67% by gravity and 29% by flotation. The head grade of 0.91 ounces per ton gold was upgraded to 8.54 ounces per ton through gravity separation, with additional flotation achieving 2.69 ounces per ton, resulting in a total concentrate of 11.23 ounces per ton.
The Fran Gold Project spans 34,360 acres and features a gold deposit extending 3,700 feet in length, up to 120 feet in width, and over 700 feet in depth. The property contains 3-4 parallel gold veins grading up to 2.6 troy ounces of gold per ton, with approximately 5,000 tons of surface material ready for shipment.

BISHOP, Calif., Jan. 10, 2025 (GLOBE NEWSWIRE) -- North Bay Resources Inc. (the “Company” or “North Bay”) (OTC: NBRI) is pleased to announce the Company has acquired, installed and began processing ore from its Fran Gold Project using new gravity separation and gold recovery equipment at its Bishop Gold Mill. Microscopic analysis of the concentrate has shown significant recovery of gold (see Picture 1). Samples have been shipped to the Company’s Metallurgy Laboratory for assay and further analyses, prior to shipment to its gold refinery partner. The processing of gold continues. The concentrate was produced using centrifugal gravity recovery in a Knudsen Bowl. The Company is also adding a Gemini Table for further gravity concentrate and concentrate upgrading purposes as part of a switch to gravity primary operation with scavenger recovery by flotation. Commissioning of the flotation circuit is underway with the arrival of reagents earlier this week and one final reagent expected within 10 days.
