North Bay Resources Inc (NBRI): Ruby Gold Project Update

SKIPPACK, PA -- (Marketwire) -- 07/23/12 -- North Bay Resources Inc. (OTCBB: NBRI) ("North Bay" or the "Company") has issued the following shareholder update on the status of current operations at the Ruby Gold Project.

As a result of safety inspections at the Ruby Mine on July 17, 2012 conducted by the federal Mine Safety and Health Administration (MSHA), the Company was found to be in non-compliance of several regulations that caused MSHA to issue a stop work order. These orders relate to the requirement to have an MSHA-approved mine rescue team on standby within a reasonable distance from the mine, insufficient documentation of MSHA-approved safety training of some of the miners, and the lack of an MSHA-approved personnel transportation rail car designated specifically for that purpose. As a result, work at the Ruby Tunnel project has been temporarily halted to allow time for the Company to comply with these issues and bring the Ruby project into full compliance with current MSHA regulations.

Prior to the work stoppage, the Ruby Tunnel rehab project continued to make steady progress, and the crew was advancing towards the 4900 Vein and the entrance to the Black Channel. This section of the tunnel, from the Ruby Portal to the 4900 Vein, is on the west side of the Melones Fault, the primary controlling structure that defines the Motherlode system of Northern California. The geological lithology of this western section is characterized by long stretches of serpentinite, which is a brittle rock structure prone to fracturing. To help insure that mining operations are not interrupted from falling rock from the serpentinite roof, we have been taking a great deal of care to retimber this stretch of tunnel as much as is deemed prudent, and in some areas installing new timbering to further reinforce the roof and ribs of the tunnel. This has been a slow and tedious process, and there remains another 600 feet or so of serpentinite to retimber before reaching the 4900 Vein.

Upon reaching the 4900 vein, we will cross over to the eastern side of the Melones Fault and into the approach to the Black Channel. It is worth noting that much of the gold produced from vein deposits of the Motherlode has been mined from the eastern side of the Melones Fault. The geological lithology of the eastern side of the Melones Fault is characterized as a slate structure, which has an inherent stability that is more self-supporting, and will not likely require nearly as much timbering. We therefore expect the work to proceed at a faster pace once we reach that section of the tunnel. By the time we reach the 4900 Vein, we will have installed over 60,000 board feet of timber, and almost 5,000 feet of new ventilation duct.

We will make an announcement when work resumes, and as always, we will continue to keep shareholders informed of our operational progress as we proceed forward towards completion of the tunnel rehab project and the start of production.
