North Bay Resources, Inc. issued the status of the South Terrace at the Ruby Mine in Sierra County, California. At the start of the shift on September 22, 2014, the raise being constructed at drillhole C2 was discovered to have encountered fast raveling serpentine below the targeted South Terrace gravels. Following the usual four-foot raise round that had been set off at the end of the previous shift, this serpentine caved up to the gravel layer above, filling the raise ore chute with broken rock and spilling over into the manway.

Prior to that date it was estimated that another 15 feet of bedrock remained between the raise and the terrace, which expected would take one more week of blasting and timbering to hole through. A new raise is now being built 100 feet downstream from the C2 raise at drill hole C0 where the ground is much more stable. The raise will be built in such a way that will be able to access the South Terrace from above rather than below.

Construction of the C0 raise began this week, and will continue until it is completed and the terrace can be safely accessed for mining. Once the C0 Raise is completed, expect that will still be able to use the ore chute at the C2 Raise for production purposes once mining in the South Terrace begins.
