North Bay Resources Inc. (NBRI) Acquires Niobium-Tantalum-REE Property

SKIPPACK, PA--(Marketwire - January 27, 2011) - North Bay Resources Inc. (OTCBB: NBRI) ("North Bay" or the "Company") is pleased to announce that the Company has acquired a 100% undivided interest in a niobium, tantalum, and rare earth elements ("REE") resource in southeastern British Columbia known as the Crescent.

The Crescent Property covers the former Tantalizing and PEG claims, and comprises 933 contiguous acres located approximately 3 kilometres northwest of Crescent Valley, BC and 24 kilometres west of Nelson, BC. Another REE prospect approximately one mile due east of the Crescent and covering 466 acres formerly known as the JAK claim group was also staked, and is now considered to be part of the Crescent project. The local infrastructure is excellent, as the property is situated near the Slocan River, is road accessible, and close to powerlines. The property was acquired by the direct staking of claims by Company personnel and the payment of statutory registration fees to the Province of British Columbia.

Historical assessment work dating back to 1956 and on file with British Columbia has documented that the Crescent Property contains pegmatites with high grade pockets of niobium and tantalum, grading up to 25.7% niobium and 9.8% tantalum. According to BC MINFILE 082FSW272, "Two of the larger quartzose pegmatite-greisen zones, 300 metres apart, measure 20 by 30 metres and 8 by 30 metres. They consist predominantly of coarse-grained feldspar with minor quartz and muscovite and contain niobium-tantalum oxide minerals. The black radioactive minerals are likely samarskite and ilmenorutile or niobium rutile. They occur as disseminations in reddish feldspar and patches up to 5 centimetres across. A chunk of samarskite assayed 5.8% uranium, 2.5% thorium, 25.7% niobium and 9.8% tantalum (Minister of Mines Annual Report 1956, page 77). In 1967, a sample from the area assayed 2.2% niobium, 0.14% uranium and 0.32% yttrium (Metcalfe, 1967). A more recent grab sample from 1985 assayed 1.25% Nb2O5 and 0.14% Ta2O5 (Assessment Report 14652)."

In 2002, a work program was conducted to assess the presence of rare earth elements ("REE"). Eight rock geochemical samples and one silt sample were collected and analyzed by Acme Laboratories using an ultratrace ICPMS and by Actlabs using neutron activation. BC Assessment Report 26855 documents anomalous indications of almost all known REEs. The table below shows the best composite REE results from the geochemical sample analysis performed in 2002, including several minerals often associated with REE deposits.

The Company intends to seek a joint-venture partner to help develop the resource.
