TSX Venture: TDC

VANCOUVER, June 11 /CNW/ - Tyhee Development Corp. (TSX Venture, TDC) (the "Company") has purchased a 100% interest in 5 mining leases (Oro Lake Property) covering 338 acres adjacent to its BigSky Property, from Norwest Explorers Ltd, an arms-length company.

"The opportunity to purchase the property adjoining BigSky was too good to pass up", said Tyhee's President and CEO, David Webb. "We will fully investigate Oro Lake's potential in conjunction with the work being carried out on the BigSky property. We continue to add to our position as the dominant property holder in the Yellowknife gold camp".

Tyhee paid Norwest Explorers Ltd (Norwest) $20,000 as a one time payment for a 100% interest in the leases. Tyhee will return the mining leases to Norwest if Tyhee:

a)  no longer wishes to retain the mining leases or
b)  fails to expend $100,000 on the leases within 5 years of the date of
    the agreement for the purchase of the leases.

Oro Lake Property

The Oro Lake Property was worked in the 1930's and 1940's, and drilled by Lynx Yellowknife Gold Mines in 1944, resulting in the discovery of a gold-bearing shear zone transecting Kam Group volcanic rocks. Narrow high-grade gold mineralization has been defined in several places along the shear zone from historic work including drillholes which returned values including 208.1 grams per tonne (gpt) gold over 0.6 metres (m) in ddh 19, 27.75 gpt gold over 1.8 m in ddh 23, and 9.92 gpt over 0.8 m in ddh 52 (Mason, J.D., 1975: Lynx Yellowknife Gold Mines., Oro Lake Area, NWT). These are historic assay results and cannot be verified. They are reported because the Company believes they are reliable, and identify a potential exploration target to guide additional work.

The mineralized structure extends onto Tyhee's BigSky Property, and is located 6.5 km south of our southern-most drillholes in our current drill program. Tyhee intends to confirm the nature of and to extend the previous work completed on the Oro Lake Property.
