GOLDEN ARROW INTERSECTS 61M AT 3.04 G/T GOLD AND 7.16 G/T SILVER ON PONCHA PROJECT, ARGENTINA
Golden Arrow Resources Corp. has released the assay results from the five-hole 1,553-metre reverse-circulation (RC) drill program carried out in November-December, 2007, on the Poncha gold-copper project in San Juan, Argentina. The five holes tested geochemical-geophysical targets within the two-kilometre by two-kilometre South target epithermal precious/base metal zone, completing the phase II drill program started in April-May, 2007.
Hole RCPC13, drilled in the northwest sector of the South target, intersected breccia-stockwork hosted gold-silver-copper-lead-zinc mineralization over a 266-metre interval, between 129 metres and 395 metres depth, that included numerous high-grade gold intercepts and wider mineralized zones, with highlights including:
266 metres at 1.21 grams per tonne gold and 3.30 grams per tonne silver (129 metres to 395 metres) including;
34 metres at 2.19 grams per tonne gold and 4.31 grams per tonne silver (129 metres to 163 metres) including;
nine metres at 4.88 grams per tonne gold and 8.43 grams per tonne silver (142 metres to 151 metres);
61 metres at 3.04 grams per tonne gold and 7.16 grams per tonne silver (270 metres to 331 metres) including;
four metres at 10.84 grams per tonne gold and 7.93 grams per tonne silver (281 metres to 285 metres);
eight metres at 10.91 grams per tonne gold and 24.00 grams per tonne silver (305 metres to 313 metres).
This strong zone of polymetallic mineralization is spatially related to a prominent induced polarization (IP) chargeability anomaly and geologically occurs along a northwest-striking contact between porphyry intrusive rock and volcaniclastic breccias which remains open in all directions.
A summary of highlights from the five holes reported herein are provided in the table attached. Results from the first part of phase II drilling on the South target included six metres grading 7.4 grams per tonne gold from DDHPC9, including one metre grading 35.03 grams per tonne gold (see news issued in Stockwatch dated Sept. 6, 2007).
Golden Arrow is earning up to a 100-per-cent interest in the Poncha project from Teck Cominco Ltd.'s subsidiary, Teck Cominco Argentina Ltd., by fulfilling expenditure and tenure maintenance requirements subject to Teck Cominco's option to re-earn up to a 65-per-cent interest in the Poncha property (see news issued in Stockwatch dated April 10, 2007).
The company is currently planning a drill program to systematically step-out from the RCPC13 discovery hole along the chargeability anomaly/porphyry contact in all directions to delineate the extent and tenor of the mineralized zone. This program will be executed either immediately before or after the Andean winter which usually extends from April to September.
Technical summary
The Poncha project is located in the Cordillera frontal of Argentina, San Juan province. The project hosts two mineralized zones; the copper-gold porphyry Northern target and the structural/breccia-related polymetallic epithermal South target. The two zones are separated by two kilometres of young, postmineral material (see April 10, 2007, news issued in Stockwatch). The geologic/genetic link between these targets has not been established yet.
Exploration in 2007 has been focused on the two-kilometre by two-kilometre South target where a hydrothermal-sulphide vein/breccia complex has been defined. Both carboniferous metasiliclastic sequences and unconformably overlying Tertiary-aged volcanic units show alteration and mineralization assemblages consistent with an intermediate sulphidation model (see Sept. 6, 2007, news issued in Stockwatch).
IP surveying has identified a northwest-southeast-oriented chargeability anomaly that underlies the central part of the South target. The anomaly is interpreted to reflect the concentration of sulphides (pyrite-galena-sphalerite) associated with epithermal mineralization and has been one of the primary targets of the phase II drill program. A total of 12 holes and 3,700.45 metres have been drilled to date on the South target, with collar spacing ranging from 220 metres to 350 metres, in both phases of drilling (2,147.45 metres of diamond core and 1,553 metres of RC).
The November-December, 2007, drill program resulted in the discovery of a new high-grade zone intercepted by PC13. Contiguous gold mineralization cut by PC13 starts at 129 metres below surface and extends for 266 metres to the bottom of the hole at 395 metres depth. Narrower zones of mineralization were intercepted by the other four holes completed in the November-December, 2007, program.
The table below presents highlights of the RC drill results for the South target for holes RCPC10-14.

The project operator (Golden Arrow) followed industry standard procedures for work carried out on the Poncha project. All RC chip samples were from one-metre intervals and the entire length of each hole was analyzed for a total of 1,521 samples. Blank, duplicate and standard samples were inserted into the sample sequence sent to the lab for quality assurance/quality control (QA/QC) purposes. In total, 108 quality control samples (over 7 per cent of all samples) were analyzed. Golden Arrow detected no QA/QC issues during review of the data.
Analyses of the RC samples were performed by Alex Stewart Assayers, in Mendoza, Argentina, an internationally recognized assay service provider. The drilling program being reported on in this news was carried out under the supervision of Daniel Bussandri, Golden Arrow's exploration manager. The technical information contained in this release has been reviewed by Dr. David A. Terry, PGeo, director and vice-president exploration for Golden Arrow, and a qualified person as defined in National Instrument 43-101.
Golden Arrow's management team is one of the most experienced in the field today. The company is focused in Argentina and Peru in highly prospective mining regions with continuing drilling on several properties. Golden Arrow has just over 15 million shares issued and outstanding, more than $5-million in cash on hand, and a 1-per-cent net smelter return royalty on a property being put into production this year.
