Additional High-Grade Lode Gold Mineralization Discovered at Mexivada Mining Corp.'s Malambani Project, ROC Congo

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/21/11 -- Mexivada Mining Corp. (TSX VENTURE: MNV)(OTCBB: MXVDF)(FRANKFURT: M2Q) is pleased to announce that the project geological team has returned from work at Mayoko on our Malambani gold and diamonds concessions in the ROC Congo (Brazzaville). The team has found new, previously undiscovered, high-grade lode gold mineralization on the Malambani Permis des Recherches gold and diamond concessions area, located southwest of Mayoko in the Republic of Congo (Brazzaville). Gold values to 25 grams per tonne gold ('g/t Au') were returned from banded iron formation and greenstone samples in three gold project areas on the Malambani concessions, 'Mifoulou', 'Ngouaka', and 'Antena.' Gold values at Mifoulou included 3 metres at 9.567 g/t Au, 7 metres at 2.31 g/t Au, and 1 metre at 25 g/t Au. Gold values at Antena and Ngouaka included 2 metres at 19.4 g/t Au, 1 metre at 7.1 g/t Au, and 3 metres at 3.45 g/t Au with a select sample at 14 g/t Au. Mexivada looks forward to the team following up on these gold mineralized areas. Map updates are being posted to Mexivada's website at www.mexivada.com.

Gem alluvial diamonds up to approximately 75 carats in size, including fancy coloured blue-green gems to 1.5 carats in size, also have been found on the property, and are still being mined by artisanal miners at several different locations. The largest gem diamonds were mined prior to 1960 at the most productive alluvial gold operations southwest of Mayoko, suggesting a structural control of both gold and diamond systems in close proximity to each other that needs to be explored further. World diamond markets and diamond prices have rebounded substantially in recent months, spurred by new buying from Chinese and India consumers.

The overall ROC Congo project of Mexivada, of which Malambani comprises a part, is subject to a 70% earn-in by Zamarat Mining Ltd., of London and Paris. Zamarat must expend $4,500,000 to earn a 70% interest in the property, including a $100,000 cash payment to Mexivada before the end of 2011. Zamarat has expressed interest in starting alluvial gold mines on the large, 1000 square kilometre Malambani property.
