Bridgeport Ventures Inc. Updates its Gold Exploration Activities in Nevada, USA

Wednesday, June 22, 2011

Bridgeport Ventures Inc. Updates its Gold Exploration Activities in Nevada, USA07:00 EDT Wednesday, June 22, 2011TORONTO, ONTARIO--(Marketwire - June 22, 2011) - Bridgeport Ventures Inc. (TSX:BPV) ("Bridgeport" or "the Company") today announced the completion of seven diamond drillholes of a ten hole program on its Blackrock property and three of six reverse circulation holes on its Hot Pot property. Geophysical, geochemical, and geological surveys are in progress on several of the Company's other gold properties. A third drill program is scheduled for Fri Gold and will commence following completion of the Phase 1 drilling at Blackrock.Bridgeport Ventures President and CEO, Shastri Ramnath said, "Although we had a slow start to the drill program at Blackrock due to poor weather and difficult access, we are now making excellent progress on both the Blackrock and Hot Pot properties and expect to announce assay results for each program following the completion of all planned drillholes."Blackrock PropertyDrilling on Bridgeport's Blackrock property, located 47 kilometres southeast of Reno, Nevada, began in March, 2011. The 3000 metre diamond drill program (ten drillholes) was designed to verify the historical gold results on the southern portion of the property and to test the gold mineralization on the northern, undrilled portion of the property.Bridgeport is currently drilling the eighth of ten planned drillholes at Blackrock. The first two drillholes of the program targeted the known mineralized zone at depth below the historical drilling followed by two drillholes targeting the southern extension of the vein system. The Company is currently drilling the fourth of six drillholes targeting the northern, untested portion of the system. Blackrock is an epithermal gold-silver mineralized system occurring in the Walker Lane Trend. Historical exploration identified a1300 metre long quartz vein system enveloped by an extensive alteration zone. Historical drillhole intersections indicate that the system is between 10 and 150 metres in width and is hosted by a structural zone crosscutting an intermediate volcanic unit. Based on the historic data, Bridgeport has interpreted the exposed mineralization as the upper portion of a deeper, higher grade deposit. Nearby gold deposits occurring in the Walker Lane Trend include the Comstock Mine (8.0 million ounces of gold), the Rawhide Mine (1.6 million ounces of gold), and the Mineral Ridge Mine (0.9 million ounces of gold). Hot Pot PropertyDrilling on Bridgeport's Hot Pot Property, located 35 kilometres northwest of Battle Mountain, Nevada, began in April, 2011. The 3000 metre reverse circulation (RC) drill program is testing for a buried, bulk tonnage, sediment-hosted gold deposit located on the northern end of the prolific Battle Mountain-Eureka trend and south of the Getchell-Turquoise Ridge trend. Unlike the deposits to the north and south of the Company's property, Hot Pot has no outcropping rocks at surface. As a result, the drillholes are targeting structural features identified by geophysics coincident with surface gold, silver, and arsenic soil anomalies. Bridgeport is currently drilling the fourth of six drillholes and the program is anticipated to finish in August, 2011.Other Exploration ActivitiesBridgeport is exploring four of the Company's other properties by completing geophysical, geochemical, and geological surveys to generate targets for drill testing.A 2000 metre reverse circulation drill program will commence on the Company's Fri Gold property following completion of the Blackrock drill program. Exploration on the Fri Gold property, located 50 kilometres north-northwest of Tonopah, Nevada, is focused on a gold-silver epithermal system identified by previous exploration companies.Potential quantity and grade of mineralization is conceptual in nature and there has been insufficient exploration to define a mineral resource on Bridgeport's, 100% owned and operated Nevada properties. It is uncertain if further exploration will result in any such targets being delineated as a mineral resource.All scientific and technical information contained in this press release has been prepared by or under the supervision of, and verified by Matthew D.
