January 22, 2009 For immediate release Release: Series 10 Release 2 TSX Venture: TDC TYHEE INCREASES YELLOWKNIFE GOLD PROJECT INDICATED GOLD RESOURCE BY 254,000 OUNCES AND INFERRED GOLD RESOURCE BY 91,000 OUNCES VANCOUVER, British Columbia (January 22, 2009)-- Tyhee Development Corp. (TSX Venture, TDC) today announced the discovery of significant gold resources on its Clan Lake and Goodwin Lake properties and the addition of these resources to the Yellowknife Gold Project. Diamond drilling completed in 2008 has identified 254,000 ounces of indicated gold resource on the Clan Lake property, and 91,000 ounces of inferred gold resource on the Goodwin Lake Property. This represents a 16% increase in the measured and indicated gold resource, as well as a 51% increase in its inferred gold resource on Tyhee’s wholly-owned Yellowknife Gold Project. Details of additions to gold resource Indicated tonnes
gold grade (gpt) ounces of gold Clan Main Zone 2,527,000 3.12 254,000 Inferred GL Vad Zone 971,000 2.91 91,000 “The substantial increase to the gold resource on our Yellowknife Gold Project represents the most significant new discovery of gold mineralization in the Yellowknife area since the mid 1980’s,” said Dr. Webb, President & CEO of Tyhee. “While this is the first resource estimate conducted on the Goodwin Lake and Clan Lake properties, it is the largest NI 43-101 resource increase ever reported by Tyhee. In addition, our technical group has extended the gold zones at Clan Lake to 6.5 km in strike with some surface grab samples from newly discovered zones returning assays over 100 gpt gold.” The Clan Lake resource was developed from 43 new diamond drillholes. Mineralization at Clan Lake is largely constrained to a 6.5 kilometre long, 900 m wide north-northeast striking domain (open in strike). Mapping and prospecting has identified significant gold mineralization throughout this zone including the 330, Pond, Main, Cranberry, Morel, Iceberg, and Cub Zones. Mineralization consists of altered, silicified, and sulphidized rocks that generally strike to the northwest and individually may exceed 100 m in width. Diamond drillhole records and drill core from previous diamond drill programs on the Clan Lake Property have been obtained. Logging and sampling of these cores has commenced and together with data that has previously been reviewed, Tyhee anticipates that additional resources will be developed. The Goodwin Lake Vad Zone (GL Vad) resource was developed from 28 diamond drillholes over a 400 m long portion of a mafic intrusion. Mineralization occurs in shallow-plunging prolate domains of silicification, and potassium and sulphide enrichment. Sulphide enrichment is minor - 2 - 2754003.1 and consists primarily of pyrrhotite, sphalerite and galena. Arsenopyrite is rare to absent. The zone is open along strike and to depth.

A search ellipsoid of 90 x 60 x 30 m was employed for Ormsby and Bruce Lake. A search ellipsoid of 60 x 25 x 25 m - 3 - 2754003.1 was employed for the Clan Lake Main Zone, and a search ellipsoid of 60 x 40 x 20 m was employed for the GL Vad Zone. All assays are composited into 1.5 m lengths, and composites for Ormsby, Nicholas Lake and Bruce Lake have a top-cut of 100 gpt gold. The Nicholas Lake resource was calculated using inverse squared estimations of 1.5 x 5 x 5 m blocks located in two domains. A search ellipsoid of 50 x 34 x 5 m at elevations above 100 m and 60 x 40 x 5 m below this elevation was employed. 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. A semi-quantitative multi-element analysis is run on 0.5 gm aliquot samples leached in a hot aqua regia solution and measured using ICP-ES techniques. 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. ll standards, duplicates,
blanks and check assays returned acceptable results. Mr. V. Pratico, P.Geol., the designated QP within the meaning of NI 43-101, has reviewed this release and approves of its content. An NI 43-101 report will be filed within 45 days of this release.
