- ATAC Resources Ltd. (TSX VENTURE:ATC - News) is pleased to announce
final 2010 diamond drill results from the Osiris area, located along the Nadaleen Trend of the Company's wholly-owned 1,600 sq/km Rackla Gold Belt in central Yukon. Based on the results
of the Osiris area drilling and new Nadaleen Fault
discoveries at the Conrad and Eaton Showings, the Company has increased its
proposed 2011 drill program to include a minimum of 40,000 m of diamond
drilling utilizing up to eight drills.
The Nadaleen
Trend is defined by a 25 km long, 5 km wide, east-west trending belt where
stream sediment samples are highly anomalous for arsenic and/or thallium and
mercury. Eight days of surface follow up and four weeks of reconnaissance
drilling within a restricted eight sq/km area of the Nadaleen
Trend revealed five significant areas of surface gold showings. Four of these
targets were drilled, resulting in three confirmed gold discoveries at the
Osiris, Conrad and Eaton Showings. The remaining 90% of the Nadaleen Trend will be aggressively explored in 2011.
Highest gold grades are associated with intense decalcification or decarbonatization and clay alteration of limestone, and
enhanced thallium content - all of which are signature characteristics of
Carlin-type mineralization.
Osiris Showing
-- Four of six broadly spaced holes along a 300 m wide fence across the
south part of the Osiris gold-in-soil anomaly yielded significant gold
bearing intercepts.
-- Multiple intersections occur in some of the holes confirming the
Company's belief that the Osiris target consists of stacked gold-bearing
intervals within favourable limestone debris flow units that are linked
by feeder structures.

(i) Previously released.
Reported intersections are drilled thicknesses. True widths are not known
as mineralization is controlled by both structure and bedding.
Drill hole OS-10-05 was collared outside
the Osiris gold-in-soil anomaly and did not intersect mineralization.
Nadaleen Fault (Conrad and Eaton Showings)
Conrad Showing
One hole at the Conrad Showing
(OS-10-08) and one hole at the Eaton Showing (OS-10-09) were drilled to test
an intense alteration zone directly associated with the Nadaleen
Fault, a regional east-west structure interpreted to be a possible feeder
structure for the Osiris area mineralized zones.
-- Alteration associated with the structure is significantly more intense
than observed in the Osiris and Isis Showings, with host limestone
(Conrad) and calcareous sandstone (Eaton) exhibiting strong clay
alteration, decarbonatization and jasperoid alteration.
-- The Nadaleen Fault is at least 5 km long and has seen very limited
prospecting elsewhere on the property. Spring water precipitate samples
taken 4 km to the west of the Conrad-Eaton area graded 15.5% arsenic. A
mineralized mafic dyke occurs along this structure, a feature of feeder
structures in the Carlin Trend.
-- Mineralization along the Nadaleen Fault has been traced by prospecting
for 500 m. Four representative rock samples collected from a 250 m long
transect along the steep hillside graded 21.4, 21.9, 40.3 and 66.6 g/t
gold, while a continuous channel sample taken across a short hand trench
that partially exposed the zone assayed 14.89 g/t gold over 2.30 m.
A single short hole was drilled to test the Conrad Showing below the hand
trench:

-- The Conrad discovery occurs at an elevation 500 m lower than the Osiris
gold discovery, confirming the significant vertical extent of multiple
stacked mineralizing systems.

OS-10-09 tested a strong alteration zone exposed in a creek cut located
approximately 300 m east of the Conrad Showing and 100 m south of the Nadaleen Fault.

(i) Reported intersections are drilled thicknesses. True widths are not
known as mineralization is controlled by both structure and bedding.
-- The mineralized intercept occurs within highly altered and silicified or
jasperoid altered calcareous sandstone, a different host rock than
identified in the other discovery areas.
-- The entire 5 km length of the Nadaleen structure is now considered a
priority drill target.
Isis Showing
The Isis Showing occurs with a limestone
debris flow unit that lies approximately 200 m stratigraphically
above the Osiris Horizon. Three areas of gold showings and/or gold-in-soil
anomalies occur along 2 km of strike length. One reconnaissance drill hole at
the west end of the target intersected a 230 m zone of decalcified limestone,
with concentrations of orpiment and realgar
(arsenic sulphides) and fine grained pyrite.
-- The intercept was geochemically anomalous with weak gold grades
throughout.
-- The remaining 2 km strike length of the Isis Horizon will be
sequentially drill tested in 2011.

"The Osiris area gold discoveries
are very exciting as they are the product of only a four week long
prospecting to reconnaissance drill program. Results confirm, that the
characteristic alteration, style, type and gold grade of Carlin-type
mineralization occur in Yukon; a first for Canada," states Graham Downs,
ATAC's CEO. "First pass exploration has been completed on only ten
percent of the highly prospective 25 km Nadaleen
Trend. Next year's project design and logistics are currently underway in
preparation for a greatly accelerated exploration program for this area and
the remaining part of the 185 km long Rackla Gold
Belt on the Company's 100% owned Rau Gold Project."
ATAC Resources Ltd. will host a
conference call and webcast to discuss the final results from the Osiris area
on December 1, 2010 at 5:30 am PST.

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.
