Aura Silver Reports High Grade Gold / Silver Assays At Greyhound -- Up To 28.2 G/T Gold And 5.38 Kilograms /T Silver
|Aura Silver Resources Inc. (TSX-V:AUU) ("Aura Silver" or the "Company") has received assays from a surface sampling program conducted during its summer exploration program on its Greyhound property in Nunavut, Canada. Gold grades are as high as 28.2 grams per tonne (g/t) while silver assays are up to 5,380 g/t. These samples were taken as part of a brief mapping and sampling program in the western part of the Greyhound property. In a previous press release (Aura Silver Extends Gold Corridor And Discovers New Base Metal Target, August 20, 2010), the Company reported preliminary results of the first phase of its drill program, which was primarily oriented to test VTEM conductors, as part of the VMS-oriented program. Assays are pending from the second phase of this program. |
The Company's Greyhound property comprises 25,333 hectares located approximately 40 kilometers north of the community of Baker Lake and 46 kilometers south of Agnico-Eagle's Meadowbank mine. The Meadowbank mine contains proven and probable reserves of 3.7 million ounces of gold at an average grade of 3.5 g/t (www.agnico-eagle.com). Infrastructure is excellent; the all-weather road from Baker Lake to the Meadowbank mine crosses through the Greyhound property, within one kilometer of this gold/silver zone discovery.
The surface geology program involved re-examining several prospects, both historic and those previously identified by Aura Silver, to determine more about the extent and geological relationships of the mineralized areas (see table below). Many of the historic prospects to the west of Whitehills Lake were re-evaluated, as well as the silver prospect to the west of Aura Lake (West Aura) and the gold prospect at the southeast corner of Aura Lake (SE Aura).
The sampling southeast of Aura Lake enabled the Company to extend the gold-rich occurrence previously identified in the 2008 sampling for about 100 meters to the south. Most surprising was that three out of the four samples taken here contain high-grade gold (0.35 to 0.93 troy oz/tonne) and 20-69 g/t silver; the fourth sample contains 171 troy oz/tonne of silver with anomalous gold. A sample taken in 2008, 500 meters SSW of the South
Aura Lake showing was previously analyzed for major elements only (no Au, only Ag) and contains 30g/t Ag, indicating that the Au-Ag zone extends at least that far. The sample taken from the original silver-lead-zinc showing to the west of Aura Lake not only confirmed its presence, but it also contains distinctly anomalous gold. Combining the evidence from the west and SE Aura occurrences, the Company now realizes that the spatially related gold and silver showings are possibly also genetically related. The possibility of a single gold-silver system enlarges both the economic prospectivity and metallurgical robustness of the Aura Lake precious metal targets. Similar sulfide-rich material was discovered up to 500 meters to the north of the SE Aura occurrence (assays pending). Furthermore, extensive silicification and quartz sulfide veining was noted during soil sampling up to 3 kilometers south of this prospect. Here the system has intersected strongly carbonatized, sulfidic and silicified iron formation, and the adjacent ultramafic rocks are intensely carbonatized and pyritized.
The Dingo showing, which is 5 kilometers NNE of the South Aura lake area, is an extensive (200m+) quartz-vein system spatially associated with the margin of the major subvolcanic intrusion that underpins all of the west Greyhound property. Although mineralization is sparse relative to that of Southeast and West Aura in this system, our samples demonstrate further the association of gold and silver.
To assess the gold potential of the identified 4 kilometer long corridor Aura Silver conducted a soil survey collecting till, soil and gossanous material for analysis. Results are pending. It is anticipated that an I.P. (induced polarization) survey will follow up this work in September. Additional geochemical work will also be carried out to expand the search area.
Robert Boaz, CEO of Aura Silver stated "These samples are of significant importance to the potential of Greyhound to host an ore deposit, particularly given that the property is hosted by strata that are very similar to those at Agnico-Eagle's Meadowbank gold mine. Further, these results prove that Aura Silver now has two highly prospective and extensive land packages; Greyhound in Nunavut and also our Taviche properties in Mexico, two mining friendly jurisdictions".
Dr. James Franklin states that these results have caused us to re-evaluate our geological model for the Aura Lake area. The potential for an extensive structurally related gold-silver system is further supported by the presence of the assay data presented herein, quartz-feldspar porphyry dykes, extensively carbonatized ultramafic rocks ("green carbonate") and intensively altered, sulfidic iron formation. All of these extend continuously from South Aura Lake for at least 3 kilometers to the south. In addition, the newly discovered VMS target approximately 2 kilometers east of Aura Lake requires follow-up geophysical work. The next phase of our program will focus on the 10 km2 area that comprises the western "core" of our Greyhound property.
