Bridgeport Ventures Inc. Announces Assay Results for Rosario, Chile

TORONTO, ONTARIO--(Marketwire - March 17, 2011) - Bridgeport Ventures Inc. (TSX:BPV) ("Bridgeport" or "the Company") is announcing the assay results from three drillholes recently completed on the Rosario Property in Chile. The diamond drill program, which commenced on January 6th, 2011, is testing a number of geological and geophysical targets identified during the 2010 drill campaign and during the 2011 ground Induced Polarization and Magnetic Survey.

Four holes have been completed in the program thus far with assays received for drillholes RDDH-013, RDDH-014, and RDDH-015. The best result was obtained in drillhole RDDH-015 which returned 0.62% copper and 0.015 g/t gold over 24m. All significant results, defined as at least 6m with greater than 0.2% copper or 0.5% lead, are summarized in Table 1.

Table 1: Drillhole results for three holes drilled on the Rosario Property.

Drillhole Depth
RDDH-013 351.0 No significant intercepts
RDDH-014 349.0 102.0 108.0 6.0 0.26 0.004 0.001
RDDH-014   246.0 282.0 36.0 0.02 0.002 0.502
RDDH-015 313.3* 14.0 20.0 6.0 0.73 0.006 0.003
RDDH-015   112.0 136.0 24.0 0.62 0.015 0.001
RDDH-015 Including 116.0 126.0 10.0 1.00 0.024 0.001

Complete results from the drill program are posted on Bridgeport's website,

Bridgeport's President and CEO, Ms. Shastri Ramnath said, "We are encouraged by the latest drill results on the Trilladore and Tamara properties. The drill program is expected to continue to the end of April at which time we will re-evaluate the geology in combination with the geophysical surveys and assay results."

The above program was carried out by Bridgeport geologists under the supervision of Matthew D. Gray, Ph.D., C.P.G. #10688, the Qualified Person for Bridgeport under National Instrument 43-101. Control samples comprised of blanks, standards and duplicates were included in the sample stream as part of a QA/QC protocol. Drill core recovery exceeded 95%. Dr. Gray reviewed the control sample data and concluded the drillhole data is reliable, that samples collected are representative of the features being drill tested and that the drillhole database meets industry standards for data quality.

Dr. Gray verified the technical information contained in this press release. Potential quantity and grade is conceptual in nature. There has been insufficient exploration to define a mineral resource on the Rosario project to date and it is uncertain if further exploration will result in such target being delineated as a resource.

For further information on the Rosario project, please refer to the technical report dated November 27, 2009 as amended December 4, 2009, entitled "Summary Report on the Rosario Copper-Gold Project, Region III, Atacama, Chile" prepared for the Company by Dr. Matthew Gray, available on SEDAR at

In January 2011, the Company exercised the option agreement to acquire the Trillador property through the payment of a $25,000 option fee, and drilling operations commenced on the property in February. Due to disappointing results from drilling on the Simonetta property in January, the Company elected to terminate its rights to the property, and wrote off $544,473 of costs associated with the property in the Quarter.
