VANCOUVER, Dec. 23 /CNW/ - Tyhee Development Corp. (TSX Venture, TDC) (the "Company") has filed an NI 43-101 compliant report entitled "Report on the Resource Estimate of the Yellowknife Gold Project" by V. Pratico, December 23, 2009.

The report discloses a total Measured and Indicated Resource for the wholly owned Yellowknife Gold Project of 1.95 million ounces of gold in 17.5 million tonnes grading 3.47 gpt and an Inferred Resource of 269,000 ounces of gold in 2.5 million tonnes grading 3.29 gpt.

This represents a 100,000 ounce increase in resources on the Clan Lake Zone which was developed with less than $500,000 in expenditures. Dave Webb, President & CEO, stated "We are very pleased with the results from our summer and fall exploration program on Clan Lake. The development of 100,000 ounces at a cost of less than $5 per ounce supports our belief in and commitment to the Clan Lake Zone and the development of the Yellowknife Gold Project". Only one half of the known strike length has been drilled to date and the Company is scheduled to restart the three diamond drills on the property in January with proceeds from their recent financing.

Progress is continuing to being made on the Preliminary Feasibility Study and the results should be available within six months. Permitting work is progressing with completion of our Developer's Assessment Report to be completed within six months.
