Highvista Gold Inc. Reports on Its Phase Two Drill Program at the Republicana Target at Its Canasta Dorada Gold Project

TORONTO, ONTARIO--(Marketwire - Aug. 22, 2012) -

THIS PRESS RELEASE, REQUIRED BY APPLICABLE CANADIAN LAWS, IS NOT FOR DISTRIBUTION TO U.S. NEWS SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

Highvista Gold Inc. ("Highvista" or the "Company") (TSX VENTURE:HVV) is pleased to report on the results of its Phase Two drill program at the Republicana Target at its 100% owned Canasta Dorada Gold Project, located within the Sonoran Gold Belt, in Sonora State, Mexico.

"We are very pleased with the results from this drill program at the Republicana Target." said Rick Adams, President and CEO of Highvista. "We continue to expand the area of gold mineralization at Republicana and have drilled our thickest intersections to date. Moreover, the mineralized structure is located near-surface and the grades of gold mineralization intersected are typical of the active gold heap-leach operations in the Sonoran Gold Belt."

La Republicana Target

The La Republicana target was initially identified through a surface mapping and sampling program conducted during 2011. Anomalous gold and silver was identified over a surface area measuring approximately 2,000 metres by 1,000 metres.

This second phase of drilling included six reverse circulation drill holes totaling 490 meters. The deepest hole, CD-12-81, was drilled to a depth of 105 metres. To date, Highvista has drilled twelve reverse circulation drill holes totaling 1,256 metres at Republicana. Significant assay results from the Phase Two program are presented in Table 1.

CD-12-82		48.5		50.1		1.6		0.428		<0.2		0.428		Hole ended in mineralization

Note: Intervals shown are hole length (true width of mineralization is unknown at present). Silver/Gold ratio of 50:1 used for gold equivalent grade (metallurgical recoveries are assumed to be 100%).

Mineralization at Republicana consists of a quartz stockwork zone within a rhyolite/metarhyolite. Drilling and rock chip sampling to date indicates that the mineralized structure is approximately 1,000 metres long (southeast to northwest), 300 to 400 metres wide (northeast to southwest), with thickness ranging from 20 metres to 100 metres. The mineralized structure dips gently to southwest (30 to 40 degrees), outcrops to the northeast and remains open to the northwest, southeast and down-dip.

"We are excited with the latest drill results at Republicana." said Rick Adams, President and CEO of Highvista. "We have discovered a second zone of gold mineralization at Canasta Dorada. Republicana represents an attractively sized target for a low-grade, bulk-tonnage gold deposit. The gold grades we are encountering at Republicana are similar to the gold grades we had at our Castillo heap-leach mine in Durango, Mexico. I note that the Measured and Indicated Gold Resources as currently reported by Argonaut Gold for the Castillo Mine are 165.7 Mt grading 0.32 g/t gold." Mr. Adams was previously a founder of Castle Gold, which constructed and operated the Castillo heap-leach mine in Durango, Mexico. Castle Gold was later sold to Argonaut Gold in early 2010.

Subject to available funding, Highvista intends to complete a twenty hole (3,000 metre) Phase 3 drill program at Republicana in the fourth quarter of 2012 and, based upon the results of this drill program, prepare a maiden resource estimate.

Qualified Person

This press release was reviewed and prepared by Rick Adams, P. Eng., the President, CEO and a Director of the Company, who is recognized as a Qualified Person under the guidelines of National Instrument 43-101.

Quality Control - Sample Preparation, Analysis and Security

All samples were recorded and delivered to the ALS Chemex sample preparation lab in Hermosillo, Sonora, Mexico by trusted Company personnel or ALS Chemex employees. Pulps of each sample were prepared in Hermosillo and sent to ALS Chemex, Vancouver, Canada, an ISO 9001-2000 certified full service laboratory. Each pulp was analyzed using 30g fire assay for gold with AAS finish (ALS method Au-AA23), and a nitric aqua regia digestion using conventional ICP-AES analysis for an additional 35 elements, including silver (ALS method ME-ICP41). Over limit samples for gold were subject to 30g fire assay with gravimetric finish (ALS code Au-GRA21) and over limit samples for silver were subjected to an aqua regia (HNO₃-HCl) digestion using conventional ICP-AES analysis (ALS code Ag-OG46). Highvista implements an Analytical Quality Assurance Program to control the analytical quality of assays in its exploration work. This program includes the systematic addition of blank samples and certified standards to each batch of samples sent for analysis at commercial laboratories. Blank samples are used to check for possible contamination in laboratories while certified standards determine the analytical accuracy and precision.

Details of quality assurance/quality control procedures for sample preparation, analysis and security are reported in detail in the Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101") compliant Technical Report filed on SEDAR (www.sedar.com) on September 27, 2011 for the Canasta Dorada Property.
