Tyhee reports additional Ormsby and Bruce Lake Zone diamond drill results, highlights include 6.5 metres of 7.250 gpt gold and 6.0 metres of 5.480 gpt gold

                   TSX Venture: TDC

                   VANCOUVER, Jan. 29 /CNW/ - Tyhee Development Corp. (TSX Venture, TDC)

(the "Company") today announced results from an additional 27 diamond

drillholes on the Ormsby Zone. Highlights include 7.250 grams per tonne (gpt)

gold over 6.5 metres (m) in NDM504 and 5.48 gpt over 6.0 m from NDM496.

                   Dave Webb, Tyhee's president and CEO said "These drillholes are part of

the 2007 program to extend the Ormsby resource both to the north and to the

south of the main body, with some infill drilling where gaps had been

identified in the previous resource blocks. Additional drill holes targeted

portions of the Bruce Lake Zone. The results include numerous intersections

between 1 and 2 metres wide, several with high gold grades, and some broader

intervals greater than 3 metres wide.

                   Much of the diamond drilling on the Ormsby Zone focused on shallow

targets in anticipation of expanding the resource potential for a conceptual

open pit. For example, NDM496 the northern-most drillhole reported here on the

Ormsby Zone intersected 6.0 m grading 5.48 gpt gold starting 32 m down hole.

This has encouraging implications in expanding our gold resource into this

area.

                   Further drilling continues on site with one drill operating on the Ormsby

Zone, and three drills active on the BigSky Property. The company is currently

revising its Nicholas Lake Zone resource to evaluate its bulk-minable resource

potential."

                   The Company's principal focus is the development of its Yellowknife Gold

Project. The Yellowknife Gold Project consists of 6,625 hectares

(15,481 acres) of mining leases located 90 km (56 miles) north of Yellowknife.

The property hosts several areas of gold mineralization, including the

partially developed Nicholas Lake Zone, the Ormsby Zone and the Bruce Lake

Zone. A 1.2 million ounce measured and indicated gold resource plus a 353,000

ounce inferred gold resource has been identified on the property as reported

June 20, 2007 (News Release S.8 R.11). Additional exploration properties

within the Yellowknife Gold Belt, including the Goodwin Lake, Clan Lake, and

BigSky Properties have been acquired. Preliminary exploration has confirmed

gold mineralization on these exploration properties.

                   Sample Analysis and QA/QC Program

                   Tyhee completed fire assays on drill core samples using 30 gram aliquots

with ICP-ES finish for gold analyses, prepared at Acme Analytical Laboratories

Ltd. in Yellowknife, and finished at Acme Analytical Laboratories Ltd in

Vancouver. Tyhee conducts a rigorous QA/QC program of inserting blanks and

duplicates in the field and standards in the laboratory. The laboratory also

conducted their own independent QA/QC program including inserting their own

standards and rerunning samples from pulped material and reject material.

These results were provided to Tyhee. All standards, duplicates, blanks and

check assays returned acceptable results. Dr. D.R. Webb, PhD, P.Geol., the

designated QP within the meaning of NI 43-101, has reviewed this release and

approves of its content.
