Tyhee Provides Update On Yellowknife Gold Project, NWT Canada
TSX Venture: TDC
1. Installation of the 2010 winter road has commenced 2. Diamond drilling at the Ormsby Zone has commenced 3. Initial metallurgical results from Clan Lake are positive
Construction of the winter road to Tyhee's Camp commenced last week due to generally cold winter conditions. It is expected that the road will be passable for light trucks within a week to ten days and will be used to resupply the camp and provide logistical support for the drills at Clan Lake. Increasingly heavy vehicles will be permitted as the ice thickness increases.
Diamond drilling at the Ormsby Zone was initiated last week to complete the geotechnical holes required for the preliminary feasibility study. The work is focused on testing sites for building foundations and other infrastructure. In addition, two combined exploration/geotechnical holes are planned to assess the geotechnical conditions of the proposed pit walls and will commence near the end of the month.
The initial results of the current metallurgical program (which is ongoing) match earlier test work to show high overall gold recoveries ranging from 90% to 97% for all zones. This test work uses conventional crush and grind, followed by three sequential recovery techniques, gravity, flotation, and cyanidation. Gravity recoverable gold for the Ormsby Deposit showed a range of 39 to 71% and 27 to 59% for Clan Lake with flotation and cyanidation raising overall recoveries into the mid to upper ninety percent range. The Clan Lake Main Zone appears to be metallurgically similar to the Ormsby Zone.

This news release contains forward-looking statements, which address future events and conditions, which are subject to various risks and uncertainties. The Company's actual results, programs and financial position could differ materially from those anticipated in such forward-looking statements as a result of numerous factors, some of which may be beyond the Company's control. These factors include: the availability of funds; the timing and content of work programs; results of exploration activities and development of mineral properties, the interpretation of drilling results and other geological data, the uncertainties of resource and reserve estimations, receipt and security of mineral property titles; project cost overruns or unanticipated costs and expenses, fluctuations in metal prices; currency fluctuations; and general market and industry conditions. Forward-looking statements are based on the expectations and opinions of the Company's management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, undue reliance should not be placed on forward-looking statements.

The resource estimates are based on geological models for which the nature and orientation of the mineralization is derived from observation of underground and surface exposures and diamond drill core. The inclusion of geological data results in a more robust resource estimate. The resource estimates conform to National Instrument 43-101 policies. The cut-off grades utilized are reported without economic implications. Cut-off grades are supported by the report prepared for Tyhee Development Corp entitled "NI 43-101 Technical Report on the Preliminary Assessment of the Yellowknife Gold Project" dated
No economic viability is implied by the cut-off grades or the mineral resource estimates. Only Mineral Reserves as defined by National Instrument 43-101 have demonstrated economic viability. The mineral resource estimates will be affected by environmental, permitting, taxation, socio-economic, marketing, political, mining, metallurgical and infrastructure issues.
