VANCOUVER, Jan. 29, 2008 (Canada NewsWire via COMTEX News Network) --

TSX Venture: TDC

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.
