Ltd., a wholly owned subsidiary of Tigris, in respect of a proposed reverse takeover that is to be conducted in accordance with the policies of the TSX Venture Exchange.

Tigris has now received TSX-V conditional acceptance for the transaction and a filing statement dated April 29, 2013, regarding the transaction has been filed under the Tigris profile on SEDAR.

Pursuant to the transaction, Tigris has also filed on SEDAR the following two National Instrument 43-101 (NI 43-101) technical reports:

About Wolfpack Gold

Wolfpack's mandate is to advance low-cost heap-leach and high-grade underground gold projects toward production in the Western United States. Wolfpack owns a significant portfolio of gold properties located in Nevada and surrounding states, and has options to acquire certain properties, including the Castle Black Rock and Adelaide properties located in Nevada. Wolfpack's portfolio has seen little to no activity since gold prices were below $400 (U.S.) per ounce. Both Adelaide and Castle Black Rock have previous operating histories as open-pit heap-leach operations during the late 1980s, when they were closed due to low gold prices.

Technical information in this press release relating to Wolfpack has been reviewed and approved by Mark J. Abrams, MSc, PG, RG, a qualified person as defined in National Instrument 43-101.
