Kutcho Copper Outlines Potential Open Pit & Underground Resource Expansion Targets
05 October 2021 - 10:30PM
Kutcho Copper Corp. (TSXV: KC, OTCQX: KCCFF)
(“Kutcho Copper” or the “Company”) is pleased to provide an
overview of exploration targets at the Kutcho project (the
“Project”) with an emphasis on open pit and underground targets at
the Main, Sumac and Esso deposits that have the potential to expand
the open pit and underground mineral resources beyond those
contemplated for inclusion in the upcoming feasibility study.
“We are finalizing a detailed exploration plan
for the Project that provides numerous opportunities to increase
the open pit and underground mineral resources available for
inclusion in future mine plans at the existing Main, Sumac and Esso
deposits,” said Vince Sorace, President & CEO of Kutcho Copper.
“In addition, we plan to advance a number of green fields targets
that show potential for discovery of completely new deposits and
which have not seen any exploration conducted since 1990. The
prospective mineralized horizons that host the three existing
deposits repeat three times across our land position and VMS
deposits typically occur in clusters along favourable horizons.
With three deposits already identified along the Main-Sumac-Esso
horizon and multiple underexplored targets, the Project has the
making of a classic VMS district with significant upside
potential.”
The Kutcho Project mineral rights encompass ~90%
of the prospective Kutcho formation rocks east of Dease Lake, B.C.
These prospective volcanic rocks are folded, repeating the
favourable mineralized horizon that hosts the Main, Sumac and Esso
volcanogenic massive sulphide (“VMS”) deposits three times within
the Project boundary, including the areas hosting the known
deposits. Following an updated comprehensive review of available
technical information, significant exploration opportunities have
been identified, including several priority, drill-ready targets
prospective for the discovery and definition of additional mineral
resources.
Near Resource Targets (Figure
1)
Main Deposit
- Open Pit Shell (Target
1): 459,000 tonnes of inferred mineral resources grading
1.35% copper equivalent (“CuEq”) (comprised of 0.78% Cu, 1.24% Zn,
0.60g/t Au and 16.8g/t Ag) lie within a 0.45% CuEq cut-off grade
pit shell for the Main deposit. and available for potential
conversion into the measured and indicated mineral resource
categories through additional drilling. This represents about 2.3%
of the total combined estimate of open pit mineral resources for
the Main deposit and has the potential to not only increase the
material available processing but also reduce the strip ratio by
converting material being treated as waste in the upcoming
feasibility study into material available to feed the mill.
- Main-Sumac Gap (Target
2): The western margin of the Main deposit is partially
open and joins the ‘Main-Sumac Gap’ where a 400m by 380m panel
between the adjacent Main and Sumac deposits is untested by
drilling. The near surface portion of this target could have
potential to be an open pit target. A conductive geophysical
anomaly coincides with the area and is ~360m long. K003, the most
eastern hole to intersect the Sumac deposit and located on the
western margin of the gap, returned 5.12m (estimated true thickness
of 4.32m) of 1.29% Cu, 0.49% Zn and 7g/t Ag). Discovery of
additional mineralization in this area could potentially result in
an expanded open pit or be accessed from the proposed underground
decline connecting the Main and Esso deposits.
- Underground & Down dip
(Target 3): 1,717,000 tonnes grading 1.87% CuEq (comprised
of 1.19% Cu, 1.90% Zn, 0.49g/t Au, 26.1g/t Ag) of Main deposit
Inferred mineral resources lies below the pit shell using a 1.05%
CuEq cut-off grade. This represents about 68.4% of the total
combined estimate of underground mineral resources for the Main
deposit and are available for potential conversion into the
measured and indicated mineral resource categories. In addition,
over 35% of the Main deposit remains open down-dip.
- Footwall Zone (“FWZ”)
(Target 4): The FWZ target comes near to surface, lies
stratigraphically beneath the Main deposit and south of the open
pit design. The FWZ is open to the east and partially down
dip. Drill hole E057, near its eastern margin,
intersected 1.5 m of 3.54% Cu, 6.94% Zn, 316.9g/t Ag and 1.47g/t
Au. The FWZ is also open at depth and could represent a parallel
mineralizing horizon. Stacked mineralizing horizons are common in
VMS districts and could open up additional prospective areas to
future exploration.
Esso Deposit
- Underground & Down Dip
(Target 3): 1,624,000 tonnes grading 2.15% CuEq,
(comprised of 1.32% Cu, 1.59% Zn, 0.42g/t Au, 35.8g/t Ag) of Esso
deposit are characterized as inferred mineral resources using a
0.95% CuEq cut-off grade. This represents about 38.5% of the total
combined estimate of underground mineral resources for the Esso
deposit and have potential for conversion to measured and indicated
mineral resource through additional drilling. Conversion would
significantly increase the quantity of mineral resources available
for inclusion in potential future mine plans with minimal
additional development capital required for access. In
addition, over 50% of the strike extent of the Esso deposit remains
open down-dip.Esso West (Target
5): The Esso West expansion target is represented by a
geophysical anomaly extending 1,500m westward from the Esso
deposit, with approximately only 150m (10%) of the anomaly being
drill tested. This drilling returned several mineralized intercepts
including 7.2m of 2.0% Cu, 5.2% Zn and 17g/t Ag in hole E094B3
(estimated true thickness of 6.12m), which lies 300m west of the
Esso deposit. The 300m of prospective Kutcho horizon between hole
E094B3 and the Esso deposit is untested by drilling, as is the
further 1,000 m of prospective Kutcho horizon to the west of hole
E094B3. Any discoveries in these areas could take advantage of the
proposed underground development for the Esso deposit.
Sumac Deposit
- Sumac (Target 6):
The entire inferred mineral resource at the Sumac deposit,
consisting of 9,086,000 tonnes grading 1.49% CuEq (comprised of
1.06% Cu, 1.53% Zn, 0.16g/t Au and 16.2g/t Ag), is open down dip
and available for potential resource expansion and resource
conversion from the inferred to measured and indicated resource
categories. The underground access decline design for the Esso
deposit passes across the entire length of the Sumac deposit which
could provide drill platforms for underground drilling to convert
the Sumac deposit into higher categories of mineralization,
allowing incorporation into future mine plans with minimal
additional development.
Details regarding the estimate of mineral
resources are presented in a press release dated Sept 13, 2021 and
can be seen on the Company's web site.

Regional Targets (Figure 2)
- Target 1 – the IRJ
Northwest target was first identified as a conductor in a 1990
ground-based survey and was tested with two drill holes. The holes
intersected intensely altered and weakly copper-mineralized
intervals, as well as a thick sequence of altered lapilli tuff and
ash. The size and strength of the alteration in both holes suggests
a prospective target down dip from prior drilling efforts and is
prospective for the discovery of a new VMS deposit.
- Target 2 – the IRJ
Northeast target has been intersected by three holes drilled in
1990 that returned massive to semi-massive sulphide layers up to 1m
thick that were associated with argillaceous material. Hole E017
returned ~3m of a stringer zone with an average of 20% pyrite that
includes some massive bands, which assayed 7.3m of 0.27% Cu. The
geochemical trends suggest that a hydrothermal vent area lies
further east and that targeting higher grade mineralization should
focus on this vector in order to potentially discover a new VMS
deposit.
- Target 3 – This
target is a significant VMS-type showing located on the flank of a
felsic dome. A prospect pit was excavated and reached “mineralized
bedrock” at a depth of 1.6 m, returning assays of 0.3% Cu, 0.1% Pb,
0.1% Zn and 7g/t Ag. Soil sampling over the area defined a 400m x
500m cluster of strong Cu-Zn anomalies that are coincident with a
strong, linear, chargeability anomaly. A Cu-Zn soil anomaly
containing up to 0.15% Zn and 0.03% Cu occurs on the southwestern
flank of the same rhyolite flow/dome complex that has not been
drill tested either. Rhyolite domes are often associated with vent
areas in VMS deposits, with massive sulphides often lying on the
flanks, suggesting that Target R3 may represent a new mineralizing
centre.
- Target 4 – B-C
East is a 3.5km long conductor inferred to be overlain by 30m of
silica exhalite. Host rocks comprise a narrow band of sericite
schist with narrow lenses of massive pyrite and silica exhalite
hosted in mafic rocks. Gravity surveys produced a broad and shallow
response that suggests a diffuse zone of increased density that
could indicate disseminated or stringer-style sulphide
mineralization commonly associated with VMS deposits.
- Target 5 – The
I-PC area is associated with cherts hosted in crystal lithic tuffs
and is interpreted as a hydrothermal exhalative horizon. E024 and
90K16 are proximal drill holes which show alteration in lithic
tuffs and the presence of massive to laminated pyrite with minor
disseminated sphalerite and chalcopyrite, indicating proximity to a
productive VMS environment. This tuff unit has an apparent
thickness of 70m and occurs upstream from numerous rounded boulders
of finely banded, sphalerite- and galena-bearing chert and
exhalate, suggesting potential for a nearby sub-cropping VMS
system.

Future Exploration Plans
Kutcho Copper is assessing plans to aggressively
test these priority targets in 2022 where they have the potential
to enhance the size and scale of the Project. In conjunction with
these efforts, Kutcho Copper will also conduct an airborne
geophysical VTEM survey over portions of the property that have not
been covered by geophysical surveys in the past (Figure 2). A VTEM
survey carried out in 2011 was highly effective at confirming known
mineralization and identifying new anomalies for follow-up.
