ATAC Resources Ltd. Steps Out and Discovers Oxidized Surface Zones And Higher Grade Sulphide Hosted Mineralization at its Rau Gold Property

October 19, 2009

October 19, 2009 - ATAC Resources Ltd (TSX-V:ATC) is pleased to announce assays from 19 additional diamond drill holes at the Tiger Zone and results from surface exploration elsewhere on its wholly owned Rau property in the Keno Hill District of central Yukon. The surface exploration identified 12 new zones and related soil geochemical anomalies, which will become priority targets for drilling in 2010. The following drill results are very important because they include holes, which demonstrate that sulphide-bearing material can host substantial thicknesses of good grade gold mineralization and, which open the Tiger Zone to extension toward the southeast. Drill highlights include:

  • 3.15 g/t Au over 72.32 m in hole 09-60;

  • 4.06 g/t Au over 42.70 m in hole 09-59; and

  • 3.71 g/t Au over 36.78 m in hole 09-44.
The newly discovered surface zones were mostly found by following up high values from grid and widely spaced contour soil sampling. The best zones and their related soil geochemical anomalies are in a 500 m wide belt, which lies 2 to 5 km along strike to the northwest of the Tiger Zone. Anomalous soil geochemical values stretch intermittently for about 22 km northwesterly from the Rackla pluton along a well defined structural trend that is also marked by magnetic highs and VTEM conductors. Many of the anomalous soil sites have not yet been prospected. Surface rock samples collected from talus or recessive weathering gullies within the new zones assayed between 1 and 18.5 g/t Au. The gold-bearing material is all oxidized and some samples contain more silver, lead and zinc than is typically found at the Tiger Zone.

Holes reported in this news release are scattered throughout the Tiger Zone. The attached table lists mineralized intervals in these holes, while drill results, pertinent maps and cross-sections can be viewed in the updated PowerPoint presentation at ATAC’s website.

The new drill assays are generally consistent with the evolving deposit model, which continues to show remarkable continuity. As expected, holes near the center of the zone (09-37, 09-42, 09-43, 09-45, 09-47, 09-48, 09-59 and 09-60) returned thick sections of good grade material; while holes on the up-dip edge of the zone (09-40, 09-50, 09-51, 09-55 and 09-58) were only weakly mineralized because the mineralized horizon has been wholly or partially removed by erosion. The absence of significant mineralization in holes 09-49 and 09-52 on section line 10+500 NW and hole 09-54 on section line 9+700 NW is not surprising because they were drilled before results of nearby holes were received and are now understood to be too far up-dip to have intersected the mineralized zone.

Results from hole 09-60 are particularly significant because they comprise by far the highest grade interval of gold-bearing sulphide mineralization obtained to date from the property. The interval thickness compares favourably with the best previous sulphide intercept (hole 08-05) but the grade is nearly double (3.15 g/t Au over 72.32 m vs 1.71 g/t Au over 78.54 m). Hole 09-60 lies about 50 m west of hole 08-05.

Results from holes 09-44 and 09-61, which stepped out from the eastern end of the known zone, may be even more important. Hole 09-44 intersected the zone 75 m southeast of hole 08-05 and discovered a sulphide interval that is more than twice the gold grade of the interval in hole 08-05 and, which is also mineralogically distinct, with proportionally more pyrite and much less arsenopyrite. The intercept in hole 09-61 lies another 75 m to the southeast along strike and resembles the material in hole 09-44. None of the holes drilled in 2008 or 2009 further to the southeast tested deep enough to have reached the projected extension of the mineralized trend defined by these holes.

“We are very encouraged that the Tiger Zone continues to expand and that high grade trends of oxide and sulphide mineralization are open to further expansion on both sides of the zone” states Graham Downs ATAC’s CEO. “Discovery of new surface zones along strike of the Tiger Zone is an important milestone in our goal of developing multiple deposits within our very large land package.”

Gold determinations were carried out at ALS Chemex in North Vancouver, B.C. where samples were fine crushed before a 250 gram split was pulverized to better than 85% passing 75 microns. The pulverizing circuit was cleaned with quartz sand twice between samples. Splits of the pulverized fraction were routinely dissolved in aqua regia and analyzed for 49 elements using inductively coupled plasma (ICP) together with mass spectrometry (MS) or atomic emission spectroscopy (AES). Gold analyses were by the Au-AA26 procedure that involves fire assay preparation using a 50 gram charge with an atomic absorption spectroscopy finish.

Rigorous procedures are in place regarding sample collection, chain of custody and data entry. Certified assay standards, duplicate samples and blanks are routinely inserted into the sample stream to ensure integrity of the assay process.
