High-Grade Gold-Bearing Vein Discovered On North Brenda Property

 A recently completed program of excavator trenching on Bitterroot Resources Ltd.'s (BTT, TSX-V) 100 percent-owned North Brenda property has discovered a high-grade gold-bearing vein within a previously unexplored structural zone. The trenches tested gold-in-soil anomalies with several metres or more of glacial sediment cover.

Trench 09-01A (see attached map) cut a 25 centimetre-wide shear zone containing fragments of broken quartz veins and disseminated pyrite. The initial 10 cm sample across this zone assayed 71.4 g/t gold and 24.4 g/t silver. Stripping along trend exposed the vein for a length of 25 metres (Trench 09-01X). Five of the channel samples collected across the vein returned greater than 19 g/t gold over true widths ranging from 9 to 25 cm, with a high value of 57.6 g/t gold and 9.3 g/t silver over 11 cm (see attached table). Cross trenches have cut this mineralized vein along a strike length of 100 metres and have also intersected parallel mineralized quartz veins.

The presence of a strong hydrothermal alteration envelope around the veins and untested gold-in-soil anomalies along trend, all within a coincident magnetic low suggest the presence of an unexplored gold-bearing system on the road-accessible North Brenda property. The geological setting and style of gold mineralization are similar to the 650,000-ounce Elk gold deposit, located 20 km southwest of North Brenda.

A program of soil sampling and magnetometer surveying encompassing approximately 12 square km was undertaken in October to evaluate other prospective areas of the property. Several new gold/silver-in-soil anomalies were defined, as were two prominent copper/molybdenum-in-soil anomalies. Exploration of these targets will continue in 2010.

Mr. Charles Greig, P.Geo is the Qualified Person responsible for the design and implementation of exploration programs on the North Brenda project.
