Golden Arrow Resources Corporation (TSX-V: GRG, FRA: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company) is pleased to announce the results of 14 additional drill holes from the Phase II program at the Chinchillas silver project in Jujuy, Argentina, thirty kilometres northeast of Silver Standard's Pirquitas silver mine and eighty-five kilometres north of Glencore's Aguilar silver-lead-zinc mine.
"Our results continue to expand the near-surface mineralized zones at Chinchillas in most directions, which will impact our upcoming resource estimate. Furthermore, we are starting to define Pirquitas-style feeder zones beneath the Silver Mantos and Socavon del Diablo mineralization, indicating the potential to further expand the project" stated Brian McEwen, VP Exploration and Development.
The Company's Phase II drill program at Chinchillas has successfully concluded, having exceeded the planned 6500 metres of drilling with a total of 7286 metres completed. Results from the program will be combined with results from the previous 43 drill holes, for a total of over 13,500 metres of drill data. This data will be used to define a NI 43-101 compliant silver-lead-zinc resource and technical report in the coming months. Results are pending for 19 remaining holes from the Phase II program.
The latest drill results highlight the definition of large feeder zones beneath the Silver Mantos and Socavon zones and the expansion of the Silver Mantos Zone onto the north side of the Chinchillas basin. This area is concealed by cover and until recently was not known to host mineralization.
At Silver Mantos, drill hole CGA-60, stepped out 50 metres west and cut through the typical near surface disseminated manto mineralization hosted within volcanics filling the basin, and continued into older basement schists. Within the basement schist CGA-60 cut three well mineralized zones with a combined width of 74 metres, including 20 metres at 141 g/t silver, 35 metres at 104 g/t silver and 19 metres at 86 g/t silver. At Silver Standard's nearby Pirquitas deposit mineralization is hosted entirely within the basement schists. The high grade flat lying near-surface volcanic hosted mineralized mantos does not exist at Pirquitas, as at Chinchillas.
CGA-62 was drilled under cover 200 metres north of the Silver Mantos on the north basin slope. Strong mineralized intercepts including, 4 metres at 197 g/t silver and 2 metres at 368 g/t silver demonstrate the potential to greatly expand the Silver Mantos zone north under the cover rocks.
At Socavon del Diablo, CGA-71 was drilled 175 metres east of the main zone and targeted deeper feeder zones in the basement schists. CGA-71 successfully intercepted 32 metres at 112 g/t silver, 1.1% lead and 0.9% zinc of feeder zone mineralization.

About the Chinchillas Project
The Chinchillas project is located in the prolific Bolivian silver--zinc-tin belt which extends into northern Argentina. Golden Arrow has the option to earn a 100% interest in the Chinchillas project (details in GRG News Release dated August 3rd, 2011). The Company believes that Chinchillas has the potential to host a large silver-zinc-lead deposit. Chinchillas is a Tertiary aged maar diatreme volcanic complex that has erupted through the Paleozoic basement schists. The resulting depression or basin, filled with volcanic breccias and tuffs is at least 1.5km in diameter.
The Silver Mantos zone is situated in the western third of the basin. Shallow disseminated silver mineralization occurs within the volcanic breccias and tuffs. This is concentrated in two and locally three mineralized layers or "mantos" ranging between 2 and 48 metres thick, averaging 12 metres in thickness. In this Phase II drill program, a second style of mineralization has been identified in, and at the contact with, the Ordivician basement pelites and sandstones. This "Pirquitas-style" is characterized by silver, lead and zinc in structures and breccias within the basement schists, occurring beneath the volcanic hosts, as seen at Silver Standard's Pirquitas silver deposit located 30 kilometres southwest of Chinchillas (www.silverstandard.com).
The Socavon del Diablo zone is situated in the eastern third of the basin and mineralization was previously defined by drilling over an area of 3.5 hectares (250 m by 150 m). Mineralization includes mantos style within favourable shallow dipping volcanic tuff horizons and crosscutting feeder structures and hydrothermal breccias.

Methodology and QA/QC
Analyses of the drill core were performed by Alex Stewart Assayers, in Mendoza, Argentina, an internationally recognized assay service provider. All samples were analyzed by method ICP-MA-39 that consists of a four acid digestion followed by ICP-OES detection. Silver results >200 Ag g/t were re-analyzed by fire assay with a gravimetric finish on 50-gram samples. Lead and zinc results >10,000 ppm were re-analyzed by a 3 acids and ICP-OES detection. The Company followed industry standard procedures for the work carried out on the Chinchillas Project, with a quality assurance/quality control (QA/QC) program. Blank, duplicate and international standard samples were inserted into the drill core sample sequence sent to the laboratory for analysis. Golden Arrow detected no significant QA/QC issues during review of the data.
