Williams Creek Explorations Limited (TSX VENTURE:WCX) ("Williams Creek", "WCX",
or "the Company") is pleased to announce that it has subscribed to 10,000,000
newly issued common shares in the Tyhee Development Corporation ("Tyhee"), a
publicly-traded company (TSX VENTURE:TDC) engaged in the exploration and
development of mineral properties. Tyhee's principal project is the Yellowknife
Project in the Northwest Territories, Canada. The total cost of the shares is
$1,000,000 (CAD).


"I am especially encouraged by the size, quality and extent of the measured,
indicated and inferred gold resources of Tyhee's Yellowknife project," said
Michael Sonnenreich, Chairman and CEO of Williams Creek. "Tyhee has discovered
substantial amounts of gold which can be economically mined in an accessible and
geopolitically stable location (Tyhee NR, July 22, 2010)."


Tyhee reports 1.95 million ounces of gold in Measured and Indicated Resource
categories, which are in part inclusive of 811,200 ounces of gold in the Proven
and Probable Reserve categories. There are also 269,000 ounces of inferred gold
(Tyhee NR, July 22, 2010). The resources occur in five gold zones which are all
open to depth, two of which are also open along strike. Two new gold zones have
been discovered this year (Tyhee NR, August 11, 2010). The Yellowknife gold camp
has produced over 14.5 million ounces of gold in the past.


"Williams Creek's rationale in helping to capitalize Tyhee is to facilitate
Tyhee's continuing exploration and development of its Yellowknife project,"
added Sonnenreich. "As well, we intend for the capital to be used for Tyhee to
proceed with its ongoing demonstration of the economic viability of that
project."


The shares are accompanied by an additional 5,000,000 warrants entitling
Williams Creek to purchase a further 5,000,0000 newly issued shares in the Tyhee
Development Corporation at a price of $0.125 CAD per share within the next 24
months.


"As I have often said, Williams Creek has a three part strategy: a) to explore
its existing holdings, b) to participate in equity and joint venture agreements,
and c) to engage in royalty and finance agreements," said Sonnenreich. "The
purchase of this equity interest, as well as the accompanying warrants, is a
good example of the second part of Williams Creek's mandate, namely
participation in equity and joint venture agreements."


Williams Creek is investing side-by-side with Interinvest, an asset management
company with offices in Boston and Montreal, which acts as the non-discretionary
investment advisor to WCX. Interinvest is purchasing an additional 20,000,000
units offered in the same private placement. Mr. Sonnenreich and Dr. Hans P.
Black, chairman of Interinvest, are participating directly in the Interinvest
portion of the private placement as individuals.


"Tyhee is very pleased to have Williams Creek as a shareholder," said Dave Webb,
CEO of Tyhee. "We look forward to a constructive relationship."
