VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 21, 2007) - Bayfield Ventures Corp. (TSX VENTURE:BYV) (FRANKFURT:B4N) and Range Metals Inc. announce a 2007 program of line cutting, geophysics, reverse circulation overburden drilling, and diamond drilling has now been completed on their 50/50 joint venture Block "A" Claims property.

The Block "A" Claims property covers 132 hectares and is located in Tait township in the Rainy River District of Northwestern Ontario. The property is underlain by archean volcanic and sedimentary rocks and is 3 kilometres southwest of the #17 Zone being explored for gold by Rainy River Resources Ltd.

A total of 29 line kilometres of grid was cut with a line spacing of 50 metres. This grid covered the entire property. Horizontal loop and magnetometer surveys were carried out over 27.2 kilometres of cross lines in February 2007. A program of reverse circulation overburden drilling was carried out in February 2007. A total of 170 metres were drilled in 5 holes. Overburden ranged from 29 to 47.7 metres in thickness. Nine till samples were obtained from these 5 holes.

Diamond drilling was carried out to test conductive geophysical responses and interpreted structures in the area up ice from sites with elevated pristine gold grain counts from the overburden drilling. A total of 1299.4 metres of BQ diamond drilling in 6 drill holes was completed on the property between August 29th and September 23, 2007. All core has been sampled and analyzed. Core containing sulfide mineralization, alteration or veining was cut in half with one half sent for analysis. Indications of structure were encountered in all holes. Bedded sulfides (barren) and graphite were encountered in 3 of the 6 holes testing conductive features associated with structures on the property.

The stratigraphy and structures hosting gold mineralization on the adjoining Rainy River Resources property are believed to dip to the southwest onto Block "A" Claims. These structures could occur at an unknown depth on the property and were not targeted during the recent drill program. Structures encountered in the phase 1 drill program had no indications of near surface gold in bedrock.

The Phase 1 drill program was intended to test conductive geophysical responses and interpreted structures in the area up ice from sites with elevated pristine gold grain counts from the overburden drilling. Bayfield Ventures and Range Metals will compile and evaluate all data from the property and adjoining area to determine future work programs.
