Highvista Gold Inc. Reports on 2011 Drill Program at Its Canasta Dorada Gold Project
12.01.2012 | Marketwire
TORONTO, Jan. 12, 2012 - Highvista Gold Inc. ("Highvista" or the "Company") (TSX VENTURE:HVV) is pleased to report on the results of its 2011 drill program at its 100% owned Canasta Dorada Gold Project, located within the Sonoran Gold Belt, in Sonora State, Mexico.This phase of drilling included fourteen reverse circulation drill holes totaling 2,055 meters. Drilling was focused on three priority targets; Big Pit, La Republicana, and Las Quintas. Drilling commenced in early October and was completed in late November.
"We are excited with the results from our 2011 drill program at Canasta Dorada." said Rick Adams, President and CEO of Highvista. "We drilled three targets along a 12 kilometre strike of the major, low-angle Carnero Fault and intersected gold mineralization in all three targets. The grades of gold mineralization intersected are typical of the active gold heap-leach operations in the Sonoran Gold Belt. The information gained in this phase of drilling clearly shows that a major mineralizing system was active in the area, which is typical of systems elsewhere in the Sonoran Gold Belt that have generated large discoveries."
Big Pit Area
The Big Pit Area has been the subject of much of the prior exploration work conducted by High Desert Gold Corp. ("High Desert"), the previous owner of the Canasta Dorada Project. Prior to this current round of drilling, Highvista and High Desert had drilled 52 drill holes, at approximately 50 metre centres, that intersected the mineralized structure in the Big Pit Area. This drilling indicated that the mineralized structure was approximately 1,000 metres long (southwest to northeast), 250 metres wide (northwest to southeast), with thickness ranging from 2 metres to 40 metres and averaging approximately 10.5 metres (the true width of the intersections has not yet been estimated). Average drilled grade for the fifty two holes was approximately 0.52 g/t Au. The mineralized structure dips to the southwest and outcrops to the northeast.
Two reverse circulation holes totaling 90 metres were completed during this phase of drilling at the Big Pit Area. The drill holes were sited to test the western and southern extensions of the mineralized structure. The first hole, CD-11-76, was drilled approximately 40 metres west of the most westerly hole previously drilled by Highvista. The second hole, CD-11-77, was drilled to test the potential for a down-dip extension of the mineralized structure to the south. Assay results for the two holes are presented in Table 1.

Gold and silver mineralization at the Big Pit Area is hosted by a low-angle structural zone that underlies the area and occurs at the contact between siltstone/phyllites and overlying sandstone and intrusive rocks. "We are delighted with the results from this round of drilling at the Big Pit Area." notes Rick Adams, President and CEO of Highvista. "The mineralized structure appears to remain open to the west, and gold and silver grades drilled to date are typical of the active gold heap-leach operations in the Sonoran Gold Belt." Highvista intends to complete a ground-based geophysical survey during the first quarter of 2012 to test the potential for a southeastern extension of the Big Pit mineralization. This will be followed by a step-out drill program during the second quarter of 2012 to test further extensions of the mineralized structure to the west and south.
La Republicana Target
The La Republicana target, located approximately 4 kilometres north-west of the Big Pit, was identified through a surface mapping and sampling program conducted during 2011. To date, anomalous gold and silver has been identified over a surface area measuring approximately 2,000 metres by 1,000 metres.
Six reverse circulation holes totaling 766 metres were completed during this first phase of drilling at La Republicana. The holes were drilled over a surface area measuring approximately 700 metres by 700 metres. The deepest hole, CD-11-71, was drilled to a depth of 157 metres. Significant assay results are presented in Table 2.

Gold and silver mineralization at La Republicana is associated with quartz veinlets within a diorite/granodiorite intrusion. "We are pleased with the initial drill results at La Republicana." said Rick Adams, President and CEO of Highvista. "It appears as though we have discovered a second zone of gold mineralization at Canasta Dorada. The host for the gold and silver mineralization at La Republicana is a diorite intrusion, and we have identified this intrusion in drill holes CD-11-71 and CD-11-74, which are spaced approximately 650 metres apart. This represents an attractively sized target for a low-grade, bulk-tonnage gold deposit." Highvista intends to continue surface mapping and sampling the La Republicana target during the first quarter of 2012, and to complete a Phase 2 drill program in the second quarter of 2012.
Las Quintas Target
The Las Quintas target, located approximately 6 kilometres south-east of the Big Pit, lies atop a strong magnetic high zone measuring approximately 7 kilometres in length by 3 kilometres in width, trending to the north-east. Surface mapping and sampling to date has identified anomalous gold and silver over a 2,000 metre by 1,500 metre area.
Six reverse circulation holes totaling 1,199 metres were completed during this first phase of drilling at Las Quintas. The holes were drilled over a surface area of approximately 1,000 metres by 1,000 metres. The deepest hole, CD-11-64, was drilled to a depth of 230 metres. Assay results for the six holes are presented in Table 3.

Gold and silver mineralization is hosted within a sequence of conglomerate rocks characterized by the presence of epidote and disseminated magnetite. Preliminary mineralogical examination by SGS Minerals Services of a sample collected near the collar of drill hole CD-11-64 indicates that gold grains are interstitial to iron oxides/hydroxides. Highvista management believes the Las Quintas target exhibits many of the characteristics of a gold-magnetite skarn deposit. "We are encouraged with the results at Las Quintas to date" notes Rick Adams. "All drill holes intersected gold mineralization, and we have only tested one square kilometer of a twenty-one square kilometer target." Highvista intends to continue mapping and sampling the Las Quintas target and to complete a Phase 2 drill program in the second quarter of 2012.
