Vancouver, BC / TNW-Accesswire / March 17, 2015 / Golden Arrow Resources Corporation (TSX-V: GRG, FRA: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company") is pleased to announce the results from nine additional drill holes in the Phase IV drilling campaign at the Chinchillas silver-lead-zinc deposit in Jujuy Province, Argentina. Results from four of the holes have confirmed a significant new area of deeper mineralization in the western side of the deposit that is expected to contribute to an increase in resources. The four holes stepped out approximately 100 metres to the east, west and north, and approximately 50 metres to the south of Phase III drill hole CGA-126 that first intersected this mineralization, and all four holes encountered the same new mineralized area at depths of 160 to 180 metres.
Highlight intercepts from these drill holes include:
- 227 g/t silver equivalent ("AgEq") over 11.5 metres (79 g/t silver, 2% lead, 2.6% zinc) at 162 metres depth in CGA-148
- 102 g/t AgEq over 3 metres (47g/t silver, 1.2% lead and 0.5% zinc) followed by 1.1% zinc over 27 metres at 179 metres depth in CGA-149
- Plus 181 g/t AgEq over 41 metres (81 g/t silver, 0.7% lead, 2.4% zinc) in the upper part of the hole at 14 metres depth.
- 180 g/t AgEq over 27 metres (67 g/t silver, 1.3% lead, 2.2% zinc) at 172 metres depth in CGA-152
- 113 g/t AgEq over 21 metres (74 g/t silver and 1.2% lead) at 177 metres depth in CGA-153
- Including 317 g/t AgEq over 2 metres (214 g/t silver and 3.2% lead)
The Company also wishes to report that it has been granted a third concession to be part of the Chinchillas project. Chinchilla II covers an area of 883 hectares situated immediately to the west of the Chinchilla and Chinchilla I concessions, expanding the total project area to 2,043 hectares (5,048 acres).
"We are pleased that drilling continues to expand the areas of mineralization, especially at depth. These deeper zones have the potential to expand the resources and pit configuration significantly and therefore improve the economics of Chinchillas," commented Golden Arrow VP Exploration and Development, Brian McEwen. "In addition, the increase in the concession area gives us more targets for resources and a broader area for possible project infrastructure requirements in the future."
The planned Phase IV drill program includes up to 16,000 metres of diamond drilling designed to contribute to the eventual feasibility study. Approximately 8,400 metres of the Phase IV drilling has been completed to date. 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 2,275 metres of drilling from nine 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/i/maps/2015-03-17_NR-map1.jpg.
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.
Silver Mantos Deep target
In the Phase III drill program hole CGA-126 (reported July 24th 2014) intersected mantos-style mineralization in the tuffs of the southeast part of the Silver Mantos area at a much deeper level than previously seen. The main intercept averaged 31 metres of 186 g/t silver, 2.4% lead and 2.2% zinc starting at 165 metres depth. In order to test the potential to expand resources in this area, 6 holes were drilled during this Phase IV program, roughly encircling hole CGA-126 and stepping out between 65 and 128 metres: CGA-143 (reported January 19th 2015), -148, -149, -151, -152 and -153. All holes but CGA-151 intersected the new lower target, with mineralized intercepts ranging from one to 27 metres in width. The results demonstrate horizontal continuity, with mineralization in close relationship to the contact of a dacitic body, and are expected in build resources in this area. The target remains open and further drilling is necessary to fully delineate mineralization. In addition, all six holes encountered the typical Silver Mantos mineralization in the upper levels that will infill the existing resources.
Hole CGA-148 is situated 107 metres east of CGA-126. It intercepted typical upper Silver Mantos mineralization with several one to five metre intervals of significant values starting at 25 metres depth. (The upper 50 metres is to be re-drillled and sampled due to poor core recovery). The drill hole encountered the targeted tuff-hosted deep mantos mineralization at 162 metres depth with 11.45 metres averaging 79 g/t silver, 2% lead and 2.6% zinc. The dacite below also has several one metre intervals of mineralization related to sulphides veinlets.
Hole CGA-149 is located 92 metres north-northeast of CGA-126. In the upper Silver Mantos at 14 meters depth it intersected 41 metres averaging 81 g/t silver, 0.7% lead and 2.4% zinc plus another manto at 55 metres of 12 metres thickness averaging 82 g/t silver. The deep manto target was intercepted at 179 metres depth with intersections in the tuffs of three metres averaging 47 g/t silver, 1.2% lead and 0.5% zinc plus 27 metres averaging 1.1% zinc. The dacite body was intercepted starting at 489 meters. In between the deep mantos and dacite there are several one metre intervals of mineralization, indicating that with further exploration high grade feeders might be detected. This hole ended at 539 metres and it is the deepest hole drilled in the project.
Hole CGA-151 is located 128 metres northeast of CGA-126. There were several short intercepts of mineralization in the upper Silver Mantos. The deep mantos was not intersected at the expected depth. The Mantos Basement was encountered at 166 metres.
Hole CGA-152 is located 65 metres southeast of hole CGA-126. Mineralization in the upper Silver Mantos included nine metres averaging 45 g/t silver, 0.6% lead and 1.7% zinc. The deep mantos mineralization was found in the tuffs including 27 metres averaging 67 g/t silver, 1.3% lead and 2.2% zinc starting at 172 metres depth, followed by eight metres averaging 26 g/t silver and 2% zinc.
Hole CGA-153 is located 93 metres northwest of hole CGA-126. From 22 to 102 metres depth several mineralized mantos were intercepted, as shown in Table 1. Between approximately 160 and 180 metres, the Mantos Basement was intersected, and at 177 metres depth 21 metres averaged 74 g/t silver and 1.2% lead. In this interval it was expected that deep mantos would be intersected.
Holes CGA-147 and CGA-150 were collared in the northeast part of the Silver Mantos zone to test the expansion of resources in a 50 metre eastern step. CGA-150 had one small mineralized intercept but otherwise both holes were un-mineralized.
Holes CGA-154 and CGA-155 were drilled to test the northeast expansion of the Mantos Basement zone. Hole CGA-154 stepped out 48 metres east of the previously reported hole CGA-133, which returned 32 metres averaging 191 g/t silver and 2.8% lead, plus 26 metres averaging 86 g/t silver and 1.3% lead (see news release dated January 6th, 2015). CGA-154 encountered a dacitic body from 156 metres to the end of the hole. Mineralization was found in the basement rocks just above the dacite, with the best intercept of nine metres averaging 77 g/t silver.
Hole CGA-155 was located at 93 metres northeast of hole CGA-136. It encountered only limited mineralization in the basement rocks as shown in Table 1.

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.
