SANTO DOMINGO, Dominican Republic, April 25, 2013 -- Santo Mining Corporation (OTCQB:SANP), (the "Company"), is pleased to announce positive results from a geochemical reconnaissance survey of its "CHARLES" exploration application (the "Charles Claim") located in the Dominican Republic "Tireo Formation". Rock samples collected by the Company exploration team yielded a series of results up to 10.79 g/t Silver and +1.0% Copper. The Charles Claim borders Goldquest's (TSX VENTURE:GQC) renowned La Escandalosa claim.

In 2012 Goldquest reported three bonanza drill intercepts just 2.5 km from the Charles claim which was reported as being the largest gold discovery in the Dominican Republic in 20 years.

The 278 hectare Charles Claim is located in the gold, silver and copper rich Tireo Formation and lies on the eastern border of Goldquest's La Escandalosa. In March 2013 the Company's exploration team, led by Elpidio Moronta, conducted a preliminary reconnaissance and surface geochemical survey of the entire claim. Stream sediment samples were collected from the Rio Guayabo, Rio Piedra Blanca and its tributaries. Grab and outcrop rock samples were collected and several samples from the Rio Piedra Blanca to the North side of the "Loma Del Gajo Pelon" mountain along a 600 meter long by 2 meter wide mineralized vein. These rock samples were dispatched to Acme Labs in Vancouver for multi-element and fire-assay analysis and returned the following positive grades for Silver and Copper:

- 10.79 g/t Silver and >1% Copper
- 10.57 g/t Silver and >1% Copper
- 03.18 g/t Silver and >7,160 g/t Copper
- 02.27 g/t Silver and >6,832 g/t Copper

The Tireo Formation consists of an Upper Cretaceous package of sedimentary and volcanic rocks including andersite, dacite, mineralized quartz veins, volcanic breccias, diorite and volcaniclastic silicification striking a NW/SE diagonal swath in west Dominican Republic.

Ten years ago, Goldquest, in a joint venture with Goldfields Ltd, carried out a regional geochemical and prospecting program that identified several new areas of mineralization. Later, Goldquest discovered several gold and copper mineralized areas in a long 35 km group of concessions called Romero, La Escandalosa, Jenjibre, Los Comios and Loma Viejo Pedro. Just 2.5 km NW of Charles are four bonanza drill intercepts which are reported on Goldquest's website as follows:

- Hole 90: 231m grading 2.41 g/t Gold and 0.44% Copper
- Hole 92: 159m grading 4.45 g/t Gold and 0.95% Copper
- Hole 93: 258m grading 4.50 g/t Gold and 1.30% Copper
- and most recently 235m grading 7.88 g/t Gold and 1.43% Copper

According to Company President, Al French, "The Acme Lab results confirm a highly prospective area for Silver, Copper and potential Gold mineralization. Today the exploration team will return to Charles just north of San Juan and conduct a detailed sampling in the prospective zones. Meanwhile, back in Santo Domingo we are negotiating to purchase up to four more claims clustered immediately around Goldquest's bonanza claims. Funding for the exploration will potentially come from the recent $16 million commitment from Hanover Holdings I, LLC (NY).
