Aura Silver Resources Inc.: Mineral Intercepts at Second Target Zone Confirm Potential for Large Scale Silver Mineralization

OTTAWA, ONTARIO--(Marketwire - Sept. 3, 2009) - Aura Silver Resources Inc. (TSX VENTURE:AUU) ("Aura Silver" or the "Company") is pleased to report results of the latest assays from its Taviche JV Project, Oaxaca, Mexico (with Intrepid Mines; TSX:IAU). Holes HBAD06-09 to HBAD08-09 were designed to test the Santo Nino target on the Alma Delia Concession located 800 meters to the southeast of the reported drilling (press release dated August 14, 2009; holes HBET01 to HBET03) on the Mezcal structure (refer to attached Diagram). This second set of holes is part of the widespread testing of the seven kilometer long Higo Blanco jasperoid trend and is intended to confirm the large scale potential for a silver deposit.

The holes HBAD06 to HBAD08 tested near surface silver mineralization found in prior trenching and surface sampling programs. All holes at Santo Nino encountered broad zones of well developed silicified breccias with widespread pyrargyrite (containing approximately 60 wt% silver). Significant silver mineralization was encountered in both -06 and -08. Mineralization was prevalent for the first 50 meters of core in HBAD06 with a 5.5 meter interval measuring 202.4 grams per tonne (g/t) silver equivalent and a gold interval of 1.25 meters measuring 0.69 g/t at a depth of approximately 70 meters. HBAD08 encountered 1.14 kilograms/t silver equivalent over 0.95 meters at approximately 64 meters. The Higo Blanco complex clearly contains extensively developed gold (Au) and silver (Ag) mineralization along strike from the previously reported hole HBET03 to holes HBAD06 and 08 (a distance of approx. 800 meters). Much of the silver mineralization occurs in brecciated silica replacement of limestone, but a more gold-rich part of the system is associated with extensive quartz veining in the adjacent volcanic strata.

Drill holes HBET04-09 and HBET05-09 were designed to determine the location of the mineralization below HBET02 and HBET03. These holes revealed that the silver mineralization probably plunges to the southwest, and is controlled by the intersection of stratigraphic (limestone) and structural (Mezcal fault) elements. Limestone is the key reactant that caused the silver to precipitate and the prominent Mezcal structure controlled the fluid discharge. This intersection seems to be to the west and down-plunge from hole HBET03. The next phase of drilling will be designed to follow the down-plunge extension of this key intersection. The combination of stratigraphic and structural control is similar to that for the gold-rich deposits along the Carlin trend in Nevada. HBET09-09 was designed to test the eastern side of the Cerro La Mina prospect several hundred metres northeast of holes HBET01 to -05. No significant mineralization is reported in this hole. Overall, the structural and stratigraphic complexity and abundance of extensive hydro-brecciation in the Higo Blanco area point to a very large mineralized system.

Based on this preliminary assessment of the Higo Blanco property, there are two distinct and adjacent targets: a gold-enriched vein and breccia system (as observed in the holes drilled to date) to the west in the volcanic strata, and a substantial silver-rich target hosted in multistage, silicified limestone breccias hosting minor, but significant pyrargyrite and native silver (HBET02, HBET03, HBAD06, HBAD07 and HBAD08). Statistical analysis of the assay results indicates that antimony is strongly correlated with silver, and is an excellent pathfinder element for it, whereas the pathfinder for gold is arsenopyrite.

Robert Boaz, President and CEO of Aura Silver stated, "We are excited about these additional results as they confirm the large scale potential of Higo Blanco's mineralization. We are currently in the process of planning a Phase II drill program consisting of a minimum of 3,000 meters. The Phase II program will further define the geologic structure from the Piedra del Sapo prospect to Santo Nino which occurs over a five kilometer strike length."

The following table presents assay data separated into the Ag zone (silicified limestone) and Au zone (volcanic-dominated zones).

(i) Intervals shown are downhole intervals. True widths are not yet
known in the initial phase of drilling.
(ii) Silver equivalent for the purposes of this drilling program is
defined as silver grade plus 60 times gold grade. Metallurgical
recoveries and net smelter returns are assumed to be 100 per cent
for the silver equivalent value. Base metal values are not included
in the silver equivalent


Core samples collected by the Taviche JV have been analyzed by SGS Labs in Durango, Mexico for multi element geochemical analyses by ICP-OES (40 element), gold by fire assay and AAS finish (greater than 0.005 g/t) and silver by AAS (greater than 0.3 g/t). Silver values in excess of 300 g/t are re-run by fire assay. Every 10th sample, a blank is included while every 25th sample is a known standard.
