VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2012) - Tyhee Gold Corp. (News - Market indicators) ("Tyhee" or the "Company") is pleased to report the positive initial results from its joint venture partner, Williams Creek Gold Ltd's (TSX VENTURE:WCX) ("Williams Creek") geological reconnaissance and sampling program on the Big Sky joint venture, near Yellowknife, Northwest Territories, Canada. Williams Creek is earning in on 50% of the Big Sky Property from Tyhee (see Tyhee news release dated March 29, 2012.)

The rock samples are reconnaissance grab samples and were initially assayed for gold by Acme Labs in Vancouver using fire assay method 3B01 with an ICP-ES finish and additional 46 element analysis using 1EX ICP-MS. All samples containing values greater than 10,000 parts per billion (ppb) gold were re-assayed using two M150 G6.ME assays, one for the fine fraction and one for the coarse fraction of the samples, to offset the 'nugget effect'. The coarse and fine values were then combined by Acme Labs to arrive at the total grams per tonne (gm/t) reported for the samples.

The results reported here are for samples returning greater than 500ppb. These are initial results from a helicopter supported geologic mapping and sampling program involving a senior geologist and a two-man prospecting team with long experience in the Yellowknife district. The Big Sky property is located to the north along strike from, and in similar host rocks to, the prolific Yellowknife gold district. The samples were collected from both previously known and newly identified mineralized shear zones. Additional sample results are pending. A summary report on the 2012 geological investigation is expected in early October and will be used to plan follow up programs, particularly targeting highly anomalous gold values.

The following table lists the sample description, the Fire Assay ICP-ES parts per billion (ppb) gold and the combined total gold M150 G6.ME assays in grams per tonne.

These initial results are located at just seven of the mineralized zones within the Big Sky Property. Mineralized vertical shears are commonly north south trending features with variable widths and quartz vein/sulfide content. Additional assays are pending and will be released upon receipt.

Tyhee has been advised that a complete map of the 2012 sample returns will be available once all assays have been released.

Twenty samples occur at the northern portion of the Oro Lake Main Shear Zone, a 10-25m wide 2.8km long shear in mafic volcanics similar to the Giant Mine at Yellowknife, NT (samples 996286, 996292, 996293, 996294, 996296, 996298 to 996300, 996414, 996419, 996420, 996422, 996423, 996425, 996427, 996437, 996440, 996451, 996461, 996462 and 996466).

Two samples are associated with a previously unrecorded showing east of the Main Oro Shear in <25cm Arsenopyrite in quartz veins occuring on the contacts of <2m wide <12m long silicified felsic dikes (samples 996407 and 996408).

Ten samples are located within Arsenopyrite in quartz veins along the 2-8 m wide by 1.8k m long WK Zone, a previously explored mafic shear in gneiss (samples 996011, 996023, 996047, 996048, 996049, 996150, 996164, 996201, 996202 and 996349).

Five samples occur in a newly discovered 100 by 100m Soggy Bottom Zone where Arsenopyrite in thin <20 cm quartz veins is hosted by sheared gneiss (samples 996193, 996195 to 996200, 996254 and 996257).

Five of the samples are associated with the 25m wide and 100m long newly discovered Dewar's Knob showing which hosts <25cm wide, <2m long semi-massive Arsenopyrite lenses within a sheared gneiss (samples 996036, 996245, 996388, 996389 and 996390).

Eight samples occur at the historically explored Havoc Zone which hosts multiple 2-8m wide and 500m long mafic shear zones with Arsenopyrite in quartz veining (samples 996243, 996382, 996383, 996387, 996393 to 996399, 996403 and 996405).

Two of the samples occur at the Lost Drill showing in <30cm by 100m Arsenopyrite in quartz veins that are sub-parallel to local bedding in metasediments (samples 996232 and 996233).

Brian K. Briggs, President and CEO of Tyhee Gold Corp., noted, "We are pleased to have a joint venture partner like Williams Creek Gold that is willing to develop the Big Sky Property while we are focused on the nearer term development of our Yellowknife Gold Project, beginning with the nearby Ormsby and Nicolas Lake gold properties. With their help and investment, Tyhee is able to ensure that Big Sky receives the attention we are confident it merits."

About Tyhee:

Tyhee Gold Corp. ("Tyhee" or "the Company") (News - Market indicators) is focused on developing the first gold mine on its flagship Yellowknife Gold Project ("YPG") in Canada's Northwest Territories. The project is located in the same prolific Archaen Greenstone Belt as the renowned world class "Con-Giant" deposit, which produced a combined 14 million ounces of gold. Tyhee is led by a veteran, project-driven, management team committed to aggressively advancing a permitting and development path targeted to enable mine construction to begin in 2014.

An independent Feasibility Study ("FS")* has been completed (August 2012), which estimated that, at a base-case gold price of US$1,400 per ounce and a projected 4,000 tonnes-per-day processing plant comprised of a conventional gravity-flotation-cyanide process and incorporating open-pit and underground mining methods on the Ormsby, Bruce Lake, Clan Lake and Nicholas Lake deposits, the YGP is estimated to return a pre-tax net present value (NPV) at a 5% discount rate of approximately $216 million and an internal rate of return of 20% based on initial estimated capital cost of $193 million (including a 10% contingency.) At current gold prices of approximately US$1,600 per oz., the YGP would have an NPV of $375 million, an IRR of 28% and a payback period of 30 months.

The study also estimated Proven and Probable mineral reserves⁽¹⁾ for the YGP at 20,433,000 tonnes at an average grade of 2.03 grams per tonne ("g/t") gold, containing 1,334,000 ounces of gold, resulting in a mine-life of approximately 15 years. Tyhee's technical team has identified six separate gold deposits in the YGP, including Ormsby, Bruce Lake, Clan Lake, Nicholas Lake and Goodwin Lake. These areas have a combined Measured and Indicated resource⁽²⁾ estimated to total 1,715,000 ounces of gold contained in 27,115,000 tonnes at an average grade of 1.97 g/t, and Inferred resources of 487,000 ounces of gold contained in 5,774,000 tonnes at 2.62 g/t.

* The FS has been prepared based on technical and economic input by a team of consultants consisting of SRK Consulting (U.S.), Inc., (SRK), Lyntek Incorporated (Lyntek) and Knight Piésold and Co. (KP) and EBA (collectively referred to as the Consultants). National Instrument 43-101 compliant.

⁽¹⁾ The mineral reserve estimate for the YGP is shown below and was calculated by Bret C Swanson BE (Min), Principal Consultant, of SRK Consulting (U.S.), Inc. Effective Date of July 1, 2012. Reserves are inclusive of mineral resources.

⁽²⁾ The mineral resource for the YGP shown above was estimated by Jeff Volk, P. Geo. of SRK Consulting (U.S.), Inc. Effective Date of July 1, 2012.
