Mexivada Mining Announces New Private Placement and Expiration of Agreements with Canaccord and Buena Vista Gold

VANCOUVER, 08/29/12 - Mexivada Mining Corp (TSX VENTURE: MNV) (OTCBB: MXVDF) (FRANKFURT: M2Q) ("Mexivada" or the "Company") announces that the previously announced brokered private placement and acquisition of Buena Vista Gold Inc. have been terminated by mutual agreement among the parties. Mexivada now will focus on its flagship Goldstorm gold-silver property in Nevada and on drilling at its Roger Property near Matheson, Ontario, which is being funded with flow-through funds in Mexivada's treasury. Drilling at Roger is scheduled to commence on September 4, 2012 using flow-through funds in Mexivada's treasury.

Goldstorm Property, Nevada: Geologic work has resumed on our main, high-grade Clayton Vein gold-silver target at Goldstorm, and Mexivada would like to resume drilling on the property this fall. Goldstorm has good potential for both Midas-style and Carlin-style gold mineralization. A drillhole in 2010 at Goldstorm showed a mineralized shear zone approximately 30 metres wide with scattered highly anomalous gold values locally throughout the 62 metre core length of the shear zone, including 2 metres at 5.51 g/t Au over 2 m, including 9.29 g/t Au and 72.6 g/t Ag over 1 m.


Private Placement

Mexivada has received strong shareholder approval to consolidate the Company's common shares on a 3.5:1 basis. Mexivada is pleased to announce that it has arranged a non-brokered private placement on a best efforts basis of up to 15,000,000 units ("Units") of Mexivada (on a post-Consolidation basis) at a price of $0.10 per unit (the "Offering") to raise gross proceeds of up to $1.5 million. Each Unit will consist of one common share in the Company ("Share") and one full common share purchase warrant (a "Warrant"). Each whole Warrant will entitle the holder to purchase one common share of the Company at a price of $0.15 per common share for a period of 24 months following the closing date. Mexivada may pay a finder's fee in connection with the offering. The offering and the consolidation are subject to the approval of the TSX Venture Exchange. The Company anticipates closing of the Offering and Consolidation as soon as practicable, subject to receipt of all necessary regulatory approvals.

The net proceeds from the Offering will be used to fund Mexivada's exploration activities at the Company's Nevada properties and for general working capital.

Mr. Richard Redfern, Mexivada's CEO, stated, "This re-focusing of work on our flagship Goldstorm property starts a new period of excitement and project development for Mexivada and its shareholders. We will continue our efforts to bring all of our many projects to a high level of productivity and to capitalize on these opportunities in today's gold market. The commitment and competency of the members of our teams and the high quality of our gold properties will differentiate our company from others."
