VANCOUVER, BC, Dec. 2, 2021 /CNW/ - ATAC Resources Ltd. ("ATAC")
(TSXV: ATC) (OTCQB: ATADF) is pleased to provide final results from
the 2021 exploration work at its 137 km2 Connaught
property near Dawson City,
Yukon.
The road-accessible Connaught
property, located at the head of the Sixty Mile placer gold camp,
lies within the 150 km-long Sixtymile-Pika fault system that hosts
porphyry, skarn and epithermal mineralization in
Yukon and Alaska. Connaught demonstrates compelling
copper-molybdenum±gold porphyry potential along a
13 km trend and hosts 26 distinct
silver-lead-gold-copper epithermal veins.
The 2021 exploration program focused on evaluating the previously
untested copper porphyry potential.
2021 Connaught Exploration Highlights
- Rock grab samples from trenches returned up to 1.38% copper
within a quartz latite dyke and 0.25% copper with 205
ppm molybdenum in a brecciated quartz monzonite;
- Trench 21-E returned 724 ppm copper and 139 ppm molybdenum
over 84 m, including 0.12%
copper and 503 ppm molybdenum over 12
m;
- 8 trenches within a 400 x 200 m
area returned >325 ppm copper over lengths from 75
to 108 m in areas where
copper values were expected to be depleted due to surface
leaching;
- Induced Polarization (IP) and ground magnetic surveys revealed
strong geophysical anomalies coincident with trench results;
and
- Contract in place for maiden 5,000
m reverse circulation drill program in 2022.
"We are extremely encouraged by the strong trench response at
Connaught. This work has so far
tested only one of four copper porphyry target areas along a 13 km
trend, which were revealed by geochemical and geophysical work this
summer. As this is an unglaciated environment, we expected surface
leaching and depletion of copper. The grades we are seeing are
extremely exciting in this context," stated President and
CEO, Graham Downs. "With these
results we have already finalized a drill contract for a maiden
drill program targeting the porphyry in the coming exploration
season. Work next season will evaluate all four target
areas."
2021 Exploration Details
The 2021 exploration program at Connaught consisted of ten trenches, 113
regional prospecting rock samples, 2,229 soil samples, a
property-wide airborne LiDAR survey, 39 km of IP and 113 km of
ground magnetics.
Trenches 21-A through J were completed across a pre-existing
1,100 x 500 m copper- and
molybdenum-in-soil anomaly, with 8 of 10 trenches returning
>325 ppm copper over 75 - 108 m (Figure 1). Results for all trenches
are presented in the table below. No significant gold was
encountered in the trenches.

The Connaught property is in
unglaciated terrain and a copper-depleted leached cap is expected
in this environment, similar to Western Copper and Gold
Corporation's Casino project in central Yukon. The 2020 resource update for the Casino
project reported an average leached cap grade of 300 ppm copper,
0.25 g/t gold, and 1.9 g/t silver (Roth et al., 2020).
Connaught trenches 21-A through
21-H were mostly hosted within a highly oxidized and leached quartz
monzonite. Multiple phases of intrusive rocks were observed
throughout the trenching area, including a quartz monzonite
porphyry, equigranular quartz monzonite, quartz latite dike and
intrusion breccia. Higher copper grades were observed in the quartz
latite dike in Trench 21-B from 54 - 63
m, returning 0.17% copper over 9
m.
Higher coincident copper and molybdenum values associated with
intrusion breccia and quartz monzonite porphyry were observed
towards the northwest in trenches 21-D and 21-E, and this area
remains open to the northwest. Trenches 21-I and 21-J were located
south of the main soil anomaly and did not return significant assay
results.
A total of 39 km of IP and 113 km of ground magnetics surveys
were completed in 2021. Inversions show shallow, high chargeability
anomalies 50 - 80 m below the 2021
trenching area (Figure 2), which could potentially indicate a
supergene enrichment zone. A 1,000 x 500
m high resistivity feature was observed 300 - 350 m below the trenching area extending towards
the east, which could indicate potassic alteration at depth (Figure
3). Numerous other chargeability, resistivity, and magnetic
anomalies were located outside of the 2021 trenching area and will
be investigated in 2022.
Grab samples collected from a magnetite skarn 1,500 m west of the trenching area returned 0.12%
copper with 0.54 g/t gold. The skarn occurrence is located
130 m upslope of an area with highly
anomalous gold-in-soil response with values up to 0.43 g/t gold.
Historical 1988 drill holes in this area reported multiple skarn
intervals with anomalous gold, including 4.25 g/t gold over
1.68 m in hole 88-006 and 7.30 g/t
gold over 0.46 m in hole 88-008.
Five diamond drill holes were completed in 2003 by a previous
operator targeting epithermal veins, close to but outside of the
2021 trenching area. Historical drill logs from these holes
reported observed copper mineralization, however much of this
material was not assayed at the time. Drill core from these
historical 2003 holes was located and reboxed, with approximately
350 m of priority areas sawn and sent
for assay. Broad intervals of anomalous copper and molybdenum
mineralization were returned. Diamond drill hole DDH-03-003,
located 300 m south of the 2021
trenching area, returned 354 ppm copper and 107 ppm molybdenum
over 51.25 m from 106.38
m in an intrusion breccia and quartz monzonite. Historical
assays from diamond drill hole DDH-03-002 report 441 ppm copper
and 78 ppm molybdenum over 24.16 m
from surface in a highly oxidized quartz monzonite.

Connaught Geology and Mineralization
The Connaught project lies
within the northeast-trending 150 km long Sixtymile-Pika fault
system which controlled Late Cretaceous magmatism, hydrothermal
activity and associated porphyry, skarn and epithermal
mineralization in Yukon
and Alaska. The property is
underlain by Carboniferous-to-Devonian gneiss, marble and
metavolcanic rocks and Permian schist rocks which are
intruded by the Late Cretaceous Prospector Mountain
Suite granodiorite, diorite and quartz monzonite.
The Late Cretaceous Prospector Mountain Suite rocks observed to
date include multiple phases of intrusive stocks, dykes and
breccias including: equigranular quartz monzonite, quartz monzonite
porphyry, quartz latite and intrusion breccia. Copper
mineralization observed to date includes disseminated and fracture
coated malachite-tenorite ± azurite within a quartz monzonite
porphyry, disseminated chalcopyrite-pyrite within an intrusion
breccia and disseminated malachite-tenorite within a quartz latite
dyke. The copper mineralized rocks at surface are intensely
weathered, are commonly stained orange, yellow and/or brown by iron
oxides and clays and are friable to the touch and are interpreted
as a copper depleted leached cap.
The style of mineralization, lithologies and alteration observed
to date are typical of copper-gold-molybdenum porphyry systems such
as Western Copper and Gold's Casino project in Yukon and Kenorland Minerals Tanacross project
in Alaska.
QA/QC
Analytical work for rock and soil samples was completed by ALS
Minerals, with sample preparation in Whitehorse, Yukon and geochemical analyses in North Vancouver, British Columbia. Soil
samples were analyzed for gold by the Au-ICP21 procedure which
involves fire assay preparation using a 30 gram charge with an
inductively coupled plasma – atomic emission
spectrometry finish. Rock samples were analyzed for gold by the
Au-AA24 procedure which involves fire assay preparation using a 50
gram charge with an atomic absorption spectroscopy finish.
Multi-element data for 48 elements was determined for all samples
by the ME-MS61 procedure, which involves a four-acid digestion
followed by inductively coupled plasma – atomic emission
spectroscopy and inductively coupled plasma – mass
spectrometry.
Analytical work for historical core samples was completed by SGS
Canada, with sample preparation in Whitehorse, Yukon and geochemical analyses in Burnaby, British Columbia. Core samples were
fine crushed to 75% passing 2 millimeters before a 250 gram split
was pulverized to better than 85% passing 75 microns. Pulps were
analyzed for gold by the GE_FAA30V5 technique which involves fire
assay preparation using a 30 gram charge with an atomic absorption
spectroscopy finish. Multi-element data for 49 elements was
determined by the GE_ICM40Q12 technique which involves four-acid
digestion followed by inductively coupled plasma – atomic
emission spectroscopy and inductively coupled plasma – mass
spectrometry.
Results referenced in this release represent highlight results
only, and include results from 2021 and previous years. Below
detection values for gold, copper, molybdenum, silver, lead and
zinc have been encountered in soil and rock samples in these target
areas.

Exploration for ATAC and a qualified person for the purposes of
