Golden Arrow Reports Substantial Increase in Resources Following Recent 9,000 m Drill Program at the Chinchillas Silver Project
Vancouver, BC / TNW-Accesswire / August 29, 2014 / Golden Arrow Resources Corporation (TSX-V: GRG, FRA: GAC (WKN: A0B6XQ), "Golden Arrow" or the "Company") is pleased to announce an updated NI 43-101 compliant resource estimate for the Chinchillas silver-lead-zinc project in Jujuy, Argentina. This updated resource incorporates additional drill results from the recently completed 37 hole 9,000 metre core drilling program.
Highlights of the Resource Estimate
"With an approximate 60% increase in resources, Chinchillas is proving to be a deposit of significant size, and we believe it has a future as an important mining project," stated Brian McEwen, VP Exploration and Development. "The upcoming PEA will benefit from this increased resource and give us a better understanding of the mining potential. Furthermore, the deposit remains open in most directions and I am confident that our feasibility drill program will continue to expand the resource base."
- Indicated Resources of 95.9 million ounces silver equivalent (Ag Eq) at 121.1g/t Ag Eq grade (24.6 million tonnes grading 91.3 g/t silver, 0.65% lead and 0.31% zinc at a 40g/t Ag Eq cut-off)
- Represents nearly a three-fold increase in indicated resources
- Inferred Resource of 68.7 million ounces Ag Eq at 97.1 g/t Ag Eq grade (22.0 million tonnes grading 56.9 g/t Ag, 0.61% Pb and 0.68% Zn at a 40g/t Ag Eq cut-off).
- Deposit still remains open to expansion
- New resources expected to positively impact the updated Preliminary Economic Assessment, underway
A NI 43-101 Technical Report supporting disclosure of this mineral resource will be filed by Golden Arrow on SEDAR within 45 days of this press release. In addition, Golden Arrow is now working to update the Preliminary Economic Assessment (PEA) for the Chinchillas Project based on the new resources. This study is expected to be completed in the next sixty days and a corresponding NI 43-101 Technical Report including that information will then be filed by the end of the year.
Management is confident that the updated PEA will outline a compelling economic scenario to move the project forward. As such, the updated PEA will be followed by an infill drilling program to upgrade the resource categories and drill the deposit to its limits, and lead into a feasibility study.
The Chinchillas properties retain considerable promise for additional resources, particularly in the Chinchillas South area where recent drilling outlined a significant target potential. (See news release dated July 22, 2014.) A further 70% of the property areas have yet to see detailed exploration. Exploration will be conducted on these areas but will be secondary in focus to the advancement of the project towards production.
Chinchillas Geology Overview
The Chinchillas project is located in the prolific Bolivian silver--zinc-tin belt which extends into northern Argentina. Golden Arrow is earning a 100% interest in the project (details in GRG News Release dated August 3rd, 2011). Chinchillas is a Tertiary aged volcanic complex that has erupted through the Paleozoic basement schists. The resulting depression or basin, filled with volcanic tuffs and tuff breccias. Shallow disseminated silver, lead and zinc mineralization occurs in layers or "mantos" within the tuffs and breccias. A second style of silver, lead and zinc mineralization occurs in the structures and breccias in the Ordivician basement pelite and sandstone schists beneath.
Silver-lead-zinc mineralization included within the resource model occurs in four units which are differentiated based on host rock and geometry. The Silver Mantos and Socavon del Diablo zones are the upper tuff units in the western and eastern halves of the deposit respectively, with the Mantos Basement and Socavon Basement being the units hosted by the basement schists that lie generally beneath their respective tuff units.

|Total Indicated Resources

|Total Inferred Resources
- The AgEq formula used is (Pb x 39.187) + (Zn x 39.187) + (Ag x 1).
- Totals may not add correctly due to rounding
- A resource constraining shell was developed based on metal prices of US$35.00/ounce silver, US$2.00/pound zinc and US$2.00/pound lead. Within that shell, the resource has been reported using a cutoff grade of 40 g/t Ag Eq. The cutoff was determined using operating costs of US$16.00/tonne for processing, US$9.00/tonne for G&A (US$25.00/t total) with metal prices of US$22.00/oz silver, US$1.00/pound zinc and US$1.00/pound lead, and a process recovery of 90%, based on the 2014 Preliminary Economic Assessment. (See reported filed on SEDAR dated January 20th, 2014 for details.) The pit slope used for the resource shell is 45 degrees.
- Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues.
- The quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to classify these inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured category.

Methodology and QA/QC
The resource estimation was based on data from 114 drill holes comprising a total length of 19,487 metres of drilling completed by the Company to the end of July 2014, as well as 7 holes comprising a total length of 2,220 metres of drilling completed by previous operators of the project.
The samples were collected and analyzed in accordance with industry standard practice. Analyses of the drill core were performed by Alex Stewart Assayers, in Mendoza, Argentina, an ISO 9001:2008 and ISO14001: 2004 certified laboratory. All samples were analyzed by method ICP-MA-39 that consists of a four acid digestion followed by ICP-OES detection. Silver results greater than 200 Ag g/t were re-analyzed by fire assay with a gravimetric finish on 50-gram samples. Lead and zinc results greater than 10,000 ppm were re-analyzed by a 3 acid digestion and ICP-OES detection. A quality assurance/quality control (QA/QC) program following industry standard practices was incorporated with the assay program. It consisted of blank, duplicate and standard samples inserted into the drill core sample sequence sent to the laboratory for analysis.
The August 28th, 2014 mineral resource estimate for the Chinchillas Project was prepared by Kyle Howie, MAIG, in consultation with Bruce Davis, FAusIMM of BD Resource Consulting Inc and Bruce Smith, MAusIMM. The mineral resource estimate uses drill hole sample assay results and the interpretation of a geologic model that relates to the spatial distribution of silver in the deposit. Interpolation characteristics were defined based on the geology, drill hole spacing and geostatistical analysis of the data. Block grade estimates were done using Ordinary Kriging (OK) with a block size measuring 5 metres long, 5 metres wide and 5 metres high. Resources are classified initially based on geological interpretation, then further according to their proximity to sample data locations and are reported, as required under NI 43-101, according to the CIM Definition Standards for Mineral Resources and Mineral Reserves. Mineral resources, which are not mineral reserves, do not have demonstrated economic viability. The quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to classify these inferred resources as Indicated or Measured, and it is uncertain if further exploration will result in upgrading them to an Indicated or Measured category.
A NI 43-101 Technical Report supporting disclosure of this mineral resource will be filed by Golden Arrow on SEDAR within 45 days of this press release.
