Vancouver, BC / TNW-Accesswire / April 15, 2015 / Golden Arrow Resources Corporation (TSX-V: GRG, FRA: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company") is pleased to announce the results from eight additional drill holes in the Phase IV drilling campaign at the Chinchillas silver-lead-zinc deposit in Jujuy Province, Argentina. All holes encountered mineralization, and of particular note is a 107 metre (353 ft) intersection of silver, lead and zinc averaging 89 g/t silver equivalent which, together with previous drill results, may indicate a significant extension to the Socavon Basement zone on the eastern side of the deposit.
"We are very pleased with these results, in particular hole 166, which along with our previously released hole 160, appears to be delineating an extension to the Socavon Basement zone that could increase the size of the deposit." commented Golden Arrow VP Exploration and Development, Brian McEwen. "We have drilled several more holes in this area and anticipate those results will further expand this zone".
In regard to the planned Phase IV 16,000 metre drill program, approximately 11,000 metres have been completed. The deposit remains open in many directions and the Company is awaiting assay results in order to evaluate the best targets with which to complete the program. The program goals include: testing the limits of the deposit in all directions, including at depth; in-filling drill hole-spacing to facilitate the upgrade of the resource categories to Measured and Indicated, and; drilling for infrastructure and geotechnical studies.
Table 1 below includes the results of 1,183.5 metres of drilling from eight holes. A map of the drill hole locations will be posted to the Chinchillas map page on the Golden Arrow website at: http://www.goldenarrowresources.com/assets/news/2015-04-15_NRM.jpg. Interactive 3-D models of the drill holes are also available on the Golden Arrow website and at www.corebox.net.
Drill Hole Details
Mineralized intercepts are reported in Table 1. The western portion of the Chinchillas deposit includes the upper Silver Mantos zone and lower Mantos Basement zone. The eastern portion of the deposit includes the upper Socavon del Diablo ("Socavon") zone, and the lower Socavon Basement zone. The zones are all part of a volcanic vent system in which explosive volcanic activity produced diatreme breccias and tuffs in the central part of the vent (Silver Mantos and Socavon zones) and brecciated the underlying Ordovician basement schists (Mantos Basement and Socavon Basement zones). Silver-lead-zinc mineralization in the upper zones is disseminated within thick mantos (layers), and in the lower zone is mainly within the fractures of the breccias. The zones are described in detail in the most recent NI 43-101 Technical Report, filed on SEDAR on February 15th, 2015. Drill core from these holes was subject to visual inspection and qualitative analysis using a hand-held X-ray fluorescence (XRF) spectrometer for silver, lead and zinc. Based on these results, intervals deemed to have low or no mineralization had pulps composited by the laboratory prior to analysis, using equal masses, with the resulting composite samples representing 2 to 6 metre intervals.
Hole CGA-168 was drilled to test the southwest limit of the Socavon zone. Limited zinc mineralization was found close to surface and the resource is not expected to expand in this direction.
Socavon Basement Targets
Hole CGA-166 was collared 56 metres southeast of hole CGA-160, (reported April 1st, 2015) which was in turn 100 metres south of the Socavon Basement zone. At 164 metres depth hole CGA-166 intersected six metres averaging 189 g/t silver, 1.5% lead and 0.6% zinc. From 210 metres to the end of the hole at 317 metres, there is continuous mineralization averaging 41 g/t silver, 0.4% lead and 1.1% zinc. Mineralized zones are brecciated or include veinlets filled with galena-sphalerite-siderite. Both holes (CGA-160 and CGA-166) confirmed the presence of a thick subhorizontal zone of brecciated basement rocks with silver-lead-zinc mineralization of more than 100 metres thick. Additional holes were drilled in this new zone and assays are expected next month. It is anticipated that this area will extend the Socavon Basement zone and significantly increase resources.
Hole CGA-167 was collared 30 metres southeast of holes CGA-145 and CGA-157, which both encountered high grade mineralization (see news releases dated January 19th, 2015 and April 1st 2015). This hole encountered zinc mineralization in both tuffs and basement rocks, and from 46 to 155 metres averaged 0.6% zinc, with individual intercepts shown in Table 1.
North Slope Targets
The North Slope of the basin offers several targets to expand the known resources. Previous drilling north of the known resource identified mineralization in basement rocks just below or at the contact with the upper tuffs and close to dacite dikes.
Hole CGA-169 was collared in the same location as hole CGA-107 (reported May 22, 2014) but dipping -55° to the northeast (N20°E). Assays confirmed silver mineralization in the tuff unit close to surface with a best intercept of 11 metres averaging 94 g/t silver and 0.6% lead starting at 52 metres deep. Additionally, the basement rocks below the tuffs had some high grade intervals including two metres averaging 136 g/t silver and 1% lead. These results together with hole CGA-161 are expected to contribute to an expansion of the resource.
Four holes were collared on the eastern side of the North Slope, approximately 175 metres north/northwest of the drill hole CGA-157 (reported April 1, 2015) and the Socavon Basement area. Previous chip channel sampling in this area targeted a stockwork zone of iron oxide-galena-silver veinlets in an area of 50 by 50 metres, which returned values of up to 236 g/t silver in a one metre sample. Holes CGA-162, CGA-163 and CGA-164 were collared in the same location but drilled in different directions with a final depth of close to 100 metres for each. All the three holes encountered several one metre intervals with silver-lead mineralization starting at surface as shown in Table 1. Mineralization is related to the outcropping stockwork. Hole CGA-165 was located 62 metres to the southwest and showed similar values as the previous three holes. Further drilling is required in this area to connect this mineralization with the existing resources.

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 follows industry standard procedures for the work carried out on the Chinchillas Project, with a quality assurance/quality control (QA/QC) program. Blank, duplicate and 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.
