TSX Venture: TDC

VANCOUVER, April 29 /CNW/ - Tyhee Development Corp. (TSX Venture, TDC) (the "Company") today announced that 6 out of 9 drillholes into the WK shear zone have intersected gold values over a zone which extends in excess of 250 metres in strike length and to a depth of 60 metres (open).

"We have identified a gold-bearing shear zone over a significant strike-length, with gold values up to 8.69 gpt over 0.7 metres and 5.87 gpt over 1.2 metres," said Dr. D.R. Webb, President & CEO of Tyhee. "Additional shear zones will be evaluated in the current drill program before further definition drilling is continued on this shear zone as well as other structures that have demonstrated gold-bearing potential. Upon identification of additional gold-bearing shear zones, the largest and highest grade structures will be selected for further work."

(1) drillholes previously reported
Drillholes B007, 9 and 10 did not intersect significant gold values in
WK Shear. Drillholes B011, 12, and 15 to 19 and 23 tested a different
shear zone as did B022, 26, and 27, none of which intersected significant
gold values.

Diamond drilling is continuing with two drills currently active on the Ormsby Zone during break-up. The drill on BigSky has been temporarily shutdown and will restart again in May. Additional targets on Clan Lake, Goodwin Lake and at Nicholas Lake will be drilled as the three drills on our properties become available.
