Hackberry Silver Project – Drilling Update

Bitterroot Resources Ltd. (BTT, TSX -V) has commenced the Phase 2 drilling program at the

Hackberry silver project in Mohave County, AZ. The drilling program has been modified and will

now test four targets. These targets include the Silver King North, Silver King South and CMH

targets, which are located between 0.4 and 2.0 kilometres northwest of the Main Hackberry mine

site. The fourth target area is located west of the Main Hackberry mine area, where drilling will

test the projected mineralized zone approximately 90 metres down-dip of the mineralized intercept

in drill hole HB-17-06, which intersected 4.87 metres grading 259 grams Ag/tonne (estimated true

thickness 3.56 metres), including 1.65 metres grading 667 grams Ag/tonne (estimated true

thickness 1.21 metres).

The first hole of the Phase 2 program tested the Silver King South target 91 metres down-dip from

the surface expression of the underground workings. This hole intersected a n unexpected void at

a depth of 111.40 metres. The void is likely to be in the mined-out mineralized zone, based on the

presence of 3.80 metres of moderate clay alteration and mineralized veinlets in the immediate

hanging wall of the void. This indicates that the historical underground workings extend at least

50 metres further down-dip than reported in historical records . The drill rig has been moved 0.5

km northwest to test the Silver King North target.

Underground workings were excavated over 100 years ago on silver-bearing veins at the Silver

King North and Silver King South targets. The CMH target is a geophysical target which presents

as a very strong magnetic low on the Hackberry mineralized trend, 400 metres northwest of the

Main Hackberry mine. Descriptions of these targets are presented in the NI 43-101 compliant-

report titled “Hackberry Silver Property” and in geophysical survey maps available on the

Company’s website (www.bitterrootresources.com).

release is consulting geologist Glen W. Adams, PG, M.Sc.
