CALVISTA INTERSECTS 17.15 g/t GOLD OVER 4.00 METRES AND 11.34 g/t GOLD 
OVER 7.00 METRES AT ITS BUENAVISTA PROSPECT 

Calvista Gold Corporation (TSX: CVZ 

http://www.stockwatch.com/Quote/Detail.aspx?action=go&symbol=CVZ&region=C&lookup=symbol&snapshot=default 

) is pleased to announce that recent drilling at its Buenavista 
prospect, along strike from AUX Canada Acquisition Inc. Aserradero 
mineralized zones, has returned high grade gold intersections. 

Highlights from the recent Phase II drilling program at the Buenavista 
prospect include: 

DDH-44 3.00 metres @ 7.80 g/t gold, and 5.00 metres @ 3.87 g/t gold 

DDH-45 5.15 metres @ 2.56 g/t gold 

DDH-47 4.00 metres @ 5.34 g/t gold, and 7.00 metres @ 11.34 g/t gold 

DDH-48 4.00 metres @ 17.15 g/t gold, and 4.00 metres @ 4.20 g/t gold 

The Company's Chief Executive Officer, Mr. Mark Haywood, stated that 
"the number of high grade gold intersections returned from the 2,500 
metre drilling program at the Buenavista prospect are very encouraging. 
Based upon the Phase II drilling program results, the Company expects to 
publish an updated NI 43-101 mineral resource by end of this quarter."

The Phase II program at the Buenavista prospect targeted mineralized 
zones identified in our Phase I drilling program, plus along strike 
extensions from the Aseradero mineralized zones (being developed by AUX 
Canada Acquisition Inc.). 

The number of high grade intersections observed by Calvista suggests a 
porphyritic environment with disseminated gold-silver mineralization and 
associated copper. 

Selected drill hole results from our Buenavista prospect, using a 
cut-off grade of 1.0 g/t of gold, are provided in Figure 1. Selected 
results from the entire Phase II drill program are also provided in the 
Appendices. 

A 10,000 metre phase III diamond drilling program is currently being 
prepared, and is expected to commence in the last quarter of this year.
