TSX-V: QEX
VANCOUVER, BC, Feb. 9, 2021 /CNW/ - QUESTEX GOLD & COPPER
LTD. (TSX-V: QEX) ("QuestEx" or the
"Company") is pleased to announce the results from a 2020
exploration program on its 100% owned 91 square-kilometre
("km") Sofia property in
British Columbia's prolific
Toodoggone Mining District (Figure 1). Three drill-ready
exploration targets at Sofia will
be a significant part of the Company's 2021 exploration campaign,
with excellent potential for discovery of both high-grade
epithermal gold ("Au") – silver ("Ag") and porphyry
copper ("Cu")-Au mineralization.
QuestEx's 2020 exploration program at Sofia included an 11.7 line-km induced
polarization ("IP") survey, collection of 549 infill soil
samples and alteration mapping from hyperspectral analysis of 816
samples (Figure 2). Highlights of the field program include:
- Infill soil sampling expanded and further defined the strong Au
– Cu - molybdenum ("Mo") footprint of the Alexandra
occurrence to 1,000 by 500 metres ("m") with highly
anomalous soil samples up to 1,037 parts per billion ("ppb")
Au, 1.668% Cu and 240.5 parts per million ("ppm") Mo (Figure
2, Figure 3). Previously, the Alexandra occurrence had only been
tested by one 260 m drill-hole, which
bottomed in highly silicified volcanic rock grading 0.42
grams/tonne ("g/t") Au and 0.08% Cu over 21.20 m.
- Identification of a 4.4-km-long structural corridor that is
highly prospective for porphyry Cu-Au and vein-related Au
mineralization based on coincident geophysical anomalies and strong
Cu – tellurium ("Te") soil geochemical anomalies that occur
along a NW striking fault (Figure 2). Individual soil samples have
concentrations up to 0.37% Cu and 8.8 ppm Te. The entire stretch of
the structural corridor is prospective but one target stands out as
exceptional:
-
- The Tranquilo target (Figure 2) is defined by an approximately
1,300 X 600 m area with coincident
chargeability and magnetic anomalies that are in close proximity to
high Cu-Te soil samples, as well as outcropping diorite and quartz
monzonite dykes. The centre of the anomaly has a 250 m diameter greater-than (">") 50
ppb Au-in-soil anomaly.
- New soil geochemical data has better defined and extended an
undrilled and underexplored target area at the Blue-Sky zone with a
greater than 2-km-long Au-As-Pb-Zn-Ba anomaly (Figure 2).
-
- The Blue-Sky zone is partly coincident with a trend of advanced
argillic alteration (noted below) and includes new Au-in-soil
results up to 1,930.6 ppb.
- Recognition of a 2-km-long trend of "lithocap" style advanced
argillic alteration (alunite +/- diaspore-+/-pyrophyllite +/-
dickite) that is commonly associated with epithermal Au-Ag deposits
and underlying porphyry Cu-Au systems (Figure 2).
Tony Barresi, President of
QuestEx comments: "QuestEx's 100% owned Sofia Property contains
some of the most exciting gold exploration targets in British Columbia's prolific Toodoggone
district, both in terms of large porphyry copper-gold potential and
high-grade gold-silver potential. Results from our 2020 exploration
program yielded the data we needed to better identify high
potential targets for our 2021 drill program. It is astonishing
that in this mature mining and exploration district, a gem like the
Sofia property remains so
underexplored and can so easily benefit from the early-stage
exploration techniques that we deployed in 2020. With the addition
of the new data, we have identified a new high-priority
drill-target, as well as expanded and refined the size and
prospectivity of pre-existing targets. I expect 2021 to be an
exciting year with drilling planned for both our Sofia property and our KSP property, which is
located in BC's Golden Triangle".
About the Sofia Property
QuestEx's 100% owned, 91 square km, Sofia property in British Columbia's Toodoggone Mining District
is situated 35 km north of the historic Kemess Cu-Au mine and less
than 20 km east of the historic Lawyers, Baker and Shasta Au-Ag mines. It occupies strategic and
prospective ground in a district that has seen recent exploration
by world class miners including Freeport McMoRan, Centerra Gold,
Hudbay Minerals, and Hunter
Dickinson, as well as numerous junior explorers including
Benchmark Metals, Evergold and TDG Gold.
The Sofia property is underlain
by a greater than 6.5 by 4.0 km hydrothermal system represented by
i) a broad and locally intense multielement soil anomaly, ii)
localized but widespread phyllic and advanced-argillic (e.g.
lithocap-style) alteration at elevation towards the southwest side
of the system, and iii) coincident (>30 mV/V) IP chargeability
and airborne magnetic anomalies located in the Toodoggone River
valley to the northeast. A limited amount of historical drilling
(less than 5,000 m) has provided an
initial test of epithermal gold mineralization flanking the
southwestern edge of the high-elevation alteration zones (e.g. 3.51
g/t Au, and 33.06 g/t Ag over 11.6 m
from 18.3 m in drillhole SG-04-04)
and porphyry copper-gold style stockwork veining coincident with
the chargeability anomaly located in the Toodoggone River valley
(e.g. 0.12% Cu and 0.08 g/t Au over 39
m from 121 m in drill-hole
BCG-07-01). An intervening 1.5 by 6.5 km area between the
mountain-tops and the Toodoggone River valley is entirely untested
by drilling.
Drill-Ready Targets on the Sofia Property
The footprint of the mineral system on the Sofia property spans approximately
800 m in elevation between the
Toodoggone River at low elevation and the high elevation lithocap
exposed on Alunite Ridge. Exposures at differing elevation
demonstrate vertical variations in both stratigraphy and the
mineralizing system. At low elevation quartz-chalcopyrite-magnetite
veins are hosted in strongly K-feldspar altered outcrops of the
Jock Creek pluton which locally intrudes Late Triassic Takla
volcanic rock. Higher up in the system, to the southwest, Jurassic
lower and upper Toodoggone formation volcanic rocks are interpreted
to be bound and/or underlain by Jock Creek intrusive rocks and have
locally strong phyllic and advanced argillic alteration with
spatially associated epithermal Au-Ag mineralization. Within this
large and classic model of a porphyry to epithermal mineral system,
QuestEx has identified three high priority, drill-ready, targets
that will be a focus of the 2021 exploration program:
1. Sickle-Griz-Quartz Lake-Kevin
Au-Ag vein system
This target comprises epithermal, Au–Ag
rich, quartz-carbonate veins that extend intermittently over a 4.7
km strike length (Figure 2). Individual veins are up to
20 m thick and have been traced for
350 m in strike. Historical
surface sampling and trenching of the vein system have yielded
numerous high-grade results including a grab sample at Sickle Creek
with 100.2 g/t Au and 2,435 g/t Ag and another at North Ridge, 2.5
km away, with 26.9 g/t Au and 828 g/t Ag. A 2.7 km stretch of
the vein system was tested in 2004 with a single 23-hole,
3,307 m drill program that utilized
small diameter BTW core. Drilling was focused in the Quartz-Lake
area (Figure 2) where it has provided an initial test of
mineralization over a 225 m strike
length and 150 m vertical extent.
Mineralization remains open to the northwest, southeast and to
depth. At Quartz Lake the vein system comprises multiple
mineralized veins with chalcedonic quartz, amethyst, adularia, and
calcite, as well as stockwork zones and silicified breccias. The
best drill result at Quartz Lake yielded 3.51 g/t Au and 33.1 g/t
Ag over 11.6 m in drill-hole SG04-04.
QuestEx's 2021 drill program will test the Quartz Lake vein system
with the objective of evaluating its resource potential. The
program will also include step-out drilling of other high-potential
targets along the 4.7 km vein system and the inaugural drill-tests
of parallel vein systems (e.g. the Blue Sky zone) which have become
better defined during the 2020 exploration program.
2.
Alexandra
The Alexandra showing covers a 1,000 by
500 m area with highly anomalous
Au-Cu-Mo soil geochemistry, (Figure 2, Figure 3),
quartz-sericite-pyrite altered volcanic rock, and proximal airborne
magnetic highs. The 2020 exploration program significantly
increased the size of the soil anomaly with infill soil sampling,
and hyperspectral analyses of strongly altered volcanic rock
defined a coincident domain of phyllic alteration. Mineralization
identified at Alexandra to date is
consistent with an epithermal Au-rich high-sulphidation system, but
the associated broad and intense Mo-in-soil anomaly and buried
magnetic high indicate strong potential for an underlying and
associated porphyry Cu-Mo-Au system. The Alexandra occurrence has only been tested with
one 260 m deep drill-hole, which
bottomed in highly silicified volcanic rock grading 0.42 g/t Au and
0.08% Cu over 21.20 m, just as it was
approaching the outer shell of the burred magnetic anomaly. The
2021 drill campaign at Alexandra
will target near-surface epithermal gold mineralization, as well as
test for an underlying porphyry-centre which has the potential to
host a high tonnage Cu-Mo-Au deposit.
3. Newly
identified Cu-Te Structural Corridor and Tranquilo
Target
The newly identified "Tranquilo" target is located
mid-slope between the high elevation lithocap with epithermal
mineralization, and porphyry Cu-Au mineralization in the Toodoggone
River valley below (Figure 2). The target is situated along a 4.4
km NW striking normal fault, which is a focus of both chargeability
and resistivity highs, as well as locally high Cu and Te in-soil
anomalies (up to 0.37% Cu and 8.8 ppm Te). Cu-Te anomalies can be
strong indicators of either alkaline Au and base-metal vein systems
or porphyry Cu-Au systems, both of which are commonly emplaced
along structural corridors. The Tranquilo target covers a 1,300 X
600 m area centred on the fault, and
includes four soil samples that exceed 1.0 ppm Te, as well as four
(different) samples that have concentrations exceeding 0.10% Cu. A
250 m diameter > 50 ppb Au-in-soil
anomaly is centred over the most intense portion of the
chargeability anomaly. The 2021 exploration program will include
the inaugural drill test of this new target.
The anticipated 2021 exploration program exemplifies QuestEx's
strategy of advancing our most high-potential targets with drilling
while also building and quietly advancing a strong portfolio of
pipeline targets through data-compilation and science-driven
grassroots exploration.

QA/QC
Samples for the Sofia 2020
exploration program followed chain of custody between collection
and delivery to a Bureau Veritas ("BV") laboratory in
Vancouver, BC. The samples
were collected in KRAFT paper sample bags from the field and were
packed in zip-tied polyurethane bags, then in security-sealed rice
bags before being delivered directly from northern BC to the
laboratory via Bandstra Transportation Systems. Soil samples were
prepared for analysis according to BV method SS230: each sample was
dried at 60 degrees Celsius and sieved to 63 microns (230 mesh) to
collect 100 grams of material. Gold was tested by fire assay
with atomic absorption finish on a 30-gram nominal sample (method
FA430). An additional 36 elements were tested by ICP-ES/MS using an
Aqua-Regia digestion (method AQ202). Quality assurance and control
("QAQC") is maintained at the lab through rigorous use of
internal reference materials, blanks, and duplicates. An additional
QAQC program was administered by QuestEx through the use of
certified reference materials that were blindly inserted into the
sample batch. If a QAQC sample returns an unacceptable value an
investigation into the results is triggered and when deemed
necessary, the samples that were tested in the batch with the
failed QAQC sample are re-tested.
