Golden Arrow Resources Corporation (TSX-V: GRG, FSE: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company") is pleased to announce the second set of results from the Phase 1 drill program at its 100% owned Chinchillas Silver Project, in Jujuy, Argentina. In this release, Golden Arrow reports results from the Socavon del Diablo target where the highlight hole CGA-21 averaged 77 meters(m) grading 155 grams per tonne (g/t) silver equivalent* (AgEQ) from 2 m to 79 m, including 13 m grading 275 g/t AgEQ*.
Golden Arrow has now completed 2600 m in 21 holes of a planned 3000 m drill program. Analyses of the first 11 drill holes have been received and verified (CGA-17 to CGA-27). All holes have intersected significant silver-zinc-lead mineralization. The first four holes targeted the Silver Mantos area and were recently reported (see press release June 14, 2012). The following seven holes were drilled in the Socavon del Diablo target (CGA-21 to CGA-27) and are the subject of this press release. Highlights from the Socavon del Diablo drilling are shown below. More complete results are on the next page.

Socavon del Diablo
Historical drilling at Socavon del Diablo by previous operators defined a mineralized zone around an area of previous surface excavations. Golden Arrow's drilling has confirmed the continuity of this mineralization and expanded the target to an area approximately 250 m by 150 m. Mineralization includes manto-style within favorable shallow dipping volcanic tuff horizons and crosscutting feeder structures and hydrothermal breccias. All seven drill holes intersected significant near surface mineralization, with thicknesses between 3 m and 77 m. Within the zone there are typically four mineralized layers, each averaging approximately 12 m thick. Grades for silver and zinc are relatively consistent with the average of the mineralized intercepts approximately 58 g/t silver and 2% zinc. Lead is somewhat less consistent but contributes significant value. High grade intervals occur, with individual one meter samples grading up to 485 g/t Ag, 11.1% Pb and 8.5% Zn. The Socavon del Diablo target is open to expansion and future drilling will concentrate on extending this favorable area and targeting feeder zones.

* Values below 20 g/t for Ag and 0.5% for Zn and Pb are not shown. The current results are thought to approximate true width. Silver Equivalents (AgEQ) were calculated using US$28/oz. for silver, US$0.85/lb. for lead and US$0.85/lb. for zinc. Metallurgical recoveries and net smelter returns for the purpose of this calculation are assumed to be 100%.
At the completion of the Socavon del Diablo drilling, the drill rig was moved to test exploratory targets around the margins of the Chinchillas basin. Six diamond drill holes have been completed on six new targets, including Charge N, Charge S, Chinchillas, Deep 240, South Contact and Labour 4. Results are pending. The rig is currently drilling additional infill and expansion holes at Silver Mantos and is planned to return and drill further holes at Socavon del Diablo before the current Phase 1 drill program ends.
The Chinchillas project is located in the prolific Bolivian silver--zinc-tin belt which extends into northern Argentina. The Company believes that Chinchillas has the potential to host a large silver-zinc-lead deposit. Chinchillas is a Tertiary aged maar diatreme volcanic center that has intruded the Paleozoic basement schists. The resulting depression, filled with volcanic breccias and tuffs is approximately 1.5 km in diameter. Mineralization occurs within the basin, hosted in favorable volcanic tuff units, hydrothermal breccias and along faults and structural zones as well as on the margins of the basin within footwall schists and across the schist volcanic contacts. The mineralization occurs mostly as disseminations, veinlets and matrix filling. The Chinchillas project geology is most similar to the San Cristobal Mine in Bolivia where low grade Ag-Zn-Pb mineralization is mined from an open pit within a similar diatreme breccia environment. San Cristobal mine has estimated reserves (June 30, 2011) of 285 million tonnes (Mt), grading 1.41% Zn, 0.48% Pb, and 53.0 g/t Ag or 484 million ounces of silver, 4Mt zinc and 1.3 Mt lead1.
The technical information contained in this release has been prepared by Bruce Smith, Chartered Professional MAusIMM Geologist and Golden Arrow's Exploration Manager and has been reviewed by Dr. Gerald G. Carlson, Ph.D., P.Eng., Head of Exploration for Golden Arrow, both Qualified Persons as defined in National Instrument 43-101.
Analyses of the drill core were performed by Alex Stewart Assayers, in Mendoza, Argentina, an internationally recognized assay service provider. 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.
