ATAC RESOURCES LTD. MAKES NEW DISCOVERY OF 47.24 M OF 3.79 G/T GOLD AT THE ANUBIS CLUSTER
Atac Resources Ltd. has made a new gold discovery at the Anubis Cluster and has released diamond drill results from the Conrad zone. Both sites are located within the Nadaleen trend at the eastern end of Atac's 100-per-cent-owned, 1,700-square-kilometre Rackla gold project in central Yukon.
Highlights
- Rotary air blast (RAB) drilling conducted 300 metres west of the Anubis zone intersected 47.24 m of 3.79 grams per tonne (g/t) gold (ARB-15-026) at what is now called the Orion target;
- Gold mineralization in hole ARB-15-026 starting at 15.24 m and continuously mineralized to the bottom of the hole;
- The Orion discovery hole is the only RAB hole in the area that was drilled north into an extensive and pyritic siltstone unit;
- Diamond drilling at the Conrad zone intersects 124.96 m of 3.02 g/t gold and confirms continuity of mineralization in the Upper and Middle Conrad zones.
Anubis Cluster RAB drilling
Atac recently completed a six-week RAB drilling program at the 18-square-kilometre Anubis Cluster located 10 km west of the Osiris cluster of gold zones. The 2015 RAB drilling program achieved its objective of cost-effectively identifying bedrock sources of gold that are likely responsible for the adjacent surface geochemical anomalies. Numerous targets remain untested within the Anubis Cluster.
"The Orion discovery hole is the most significant drill intersection to date within the 18-square-kilometre Anubis Cluster of targets. This hole is particularly significant as it demonstrates the exploration potential of the 30 km long Nadaleen trend which is developing into a major North American Carlin-type district," stated Graham Downs, president and chief executive officer of Atac. "Our inaugural RAB drilling program has proven to be a very effective and low-cost exploration tool that has allowed us to make meaningful progress under challenging market conditions. The RAB drill will continue to be integral in testing new and existing exploration targets and supporting future diamond drill programs."

Orion target
The Orion target is located 300 m west of the Anubis discovery hole An-12-001 (8.51 m of 19.85 g/t gold) in an area of strongly anomalous gold-in-soil geochemical response that had not been previously drill tested. Mineralization at Orion occurs in both a debris flow-bearing fossiliferous limestone and a variably calcareous pyritic siltstone, but is most prevalent in a highly deformed and fractured structural setting in the hangingwall pyritic siltstone assemblage where a secondary crossfault intersects the Anubis fault. Five RAB holes were drilled from the same drill pad set-up as ARB-15-026, but ARB-15-026 was the only hole oriented north to test the pyritic siltstone. ARB-15-026 bottomed in gold mineralization.
Mapping and prospecting in the Anubis area suggest that the pyritic siltstone that hosts the most significant mineralization at Orion is a regionally extensive unit and is in contact with the Anubis fault for a strike length of over 1.5 km. An updated Orion target area map and RAB drill photo are available on Atac's website.
Conrad zone
One diamond drill hole was completed at the Conrad zone in 2015. Hole OS-15-231 was specifically drilled to: test a possible link between the Conrad Upper and Middle zones; determine the continuity of mineralization within the Upper and Middle zones; better understand the favourable near-vertical contact zone between limestone and siltstone; and step out from Conrad Lower zone mineralization discovered in hole OS-14-230 which returned 42.67 m of 3.03 g/t gold and 21.71 m of 3.15 g/t gold in 2014.

Hole OS-15-231 successfully demonstrated the potential for mineralization between the Upper and Middle Conrad zone (10.66 m of 1.78 g/t gold and 12.45 m of 2.52 g/t gold). In addition, the hole indicates that both the limestone and siltstone are mineralized in the vicinity of the near-vertical contact between the two rock units.
The Middle zone was intersected as a broad mineralized interval that returned 124.96 m of 3.02 g/t gold. Higher-grade intervals such as 9.27 m of 8.71 g/t gold, represent the intersection of the limestone/siltstone contact with flat-lying mineralized faults.
Due to technical complications, the hole was lost within the mineralized limestone/siltstone contact corridor at 482.50 m, approximately 170 m short of the expected Lower zone target.
"We are very encouraged by the discovery of significant new mineralization at the Orion target in the Anubis Cluster. The discovery demonstrates the considerable potential of the pyritic siltstone to host significant gold mineralization," stated Julia Lane, vice-president, exploration, of Atac Resources. "While our 2015 drilling at the Conrad zone was unsuccessful in reaching the anticipated Lower zone target, we gained valuable geologic and mineralogical information that will continue to guide Atac's three-dimensional modelling of the Conrad zone."
Rau trend
Phase 2 exploration is currently continuing within the Rau trend and consists of: regional sampling to follow-up on encouraging results from a widely spaced sampling program (see Atac news release dated Jan. 23, 2013) and optimization work recommended in the Tiger deposit preliminary economic assessment (see Atac news release dated July 23, 2014). The results from this phase will be released when available.
QA/QC (quality assurance/quality control)
Diamond drill samples were forwarded to ALS Minerals in Whitehorse, Yukon, where they were fine crushed before a 250-gram split was pulverized to better than 85 per cent passing 75 microns. The pulverizing circuit was cleaned with quartz sand twice between samples. Pulps were then analyzed at ALS Minerals in North Vancouver, B.C., where gold determinations were carried out. Splits of the pulverized fraction were dissolved using a multiacid digestion and analyzed for 49 elements using inductively coupled plasma (ICP) together with mass spectrometry (MS) and 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 (AAS) finish. Mercury analyses were digested with aqua regia and analyzed by inductively coupled plasma mass spectrometry (ICP-MS).
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 of diamond drill samples to ensure integrity of the assay process. All diamond drill samples included in this news release have passed the QA/QC procedures as described above.
RAB drilling is a very effective exploration tool, but does not provide the detailed level of geological and structural information as does diamond drilling. Accordingly, RAB drilling is primarily used as an early- to intermediate-stage exploration tool and the results cannot be used for the purposes of NI 43-101 mineral resource estimates.
The technical information in this news release has been approved by Julia Lane, PGeo, vice-president, exploration, for Atac and a qualified person for the purposes of National Instrument 43-101.
