Kutcho Copper
Expands High-grade Mineral Resources to 17.26 MT of Measured &
Indicated at 2.61% CuEq1 and 10.71MT of Inferred at
1.67% CuEq1;
Outlines Additional Near Resource
Targets
Vancouver, B.C. --
March 4th, 2019 -- InvestorsHub NewsWire -- Kutcho Copper Corp.
(TSXV: KC) (OTC: KCCFF)
(“Kutcho Copper” or the “Company”) is pleased to
provide an updated mineral resource estimate that will be used as
the basis for its upcoming Feasibility Study on its 100% owned
Kutcho high grade copper-zinc project located in British Columbia
(“Kutcho Project”). The mineral resource estimate was prepared
under the direction of Robert Sim, P.Geo, with the assistance of
Bruce Davis, PhD, FAusIMM, by SIM Geological Inc.
(SGI).
“We are
pleased to announce an updated mineral resource estimate for the
Kutcho Project that incorporates the significant work and new
drilling conducted by Kutcho Copper during our first full year of
ownership. The updated mineral resource includes a substantial 84%
increase in inferred mineral resources compared to the 2017
resource estimate*. In addition, there remains significant
exploration potential between, below and along strike from the
existing mineral resources, providing further upside opportunities
to grow the size of the project. This expanded mineral resource
will form the foundation for the Feasibility
Study, which is slated to be
completed in Q2/Q3 2019”, stated Vince Sorace, President & CEO
of Kutcho
Copper.

The estimates in the table
are considered to be amenable to underground extraction methods.
The base case cut-off grade is 1.2% CuEq based on the formula
CuEq = (Cu% x 0.825) + (Zn% x 0.302) + (Ag g/t x 0.004) +
(Au g/t x 0.262). Mineral resources are not mineral reserves
because the economic viability has not been
demonstrated.

$10/t, copper price US $3.00/lb, zinc price US $1.25/t, gold price

Effective date of resource
estimate February 22nd, 2019
-
Inferred mineral resources
are considered too speculative geologically to have economic
considerations applied to them that would enable them to be
categorized as mineral reserves. There is also no certainty that
these inferred mineral resources will be converted to the measured
and indicated categories through further drilling, or into mineral
reserves, once economic considerations are
applied.
-
Assumptions used to derive
the cut-off grades in order to meet the NI43-101 requirement for
mineral resource estimates to demonstrate “reasonable prospects for
eventual economic extraction”. The cut-off grades to be used in the
upcoming feasibility study may vary from those used to limit the
mineral resources reported herein, as the inputs to that study are
determined. No inference is implied in the changes to the
assumptions used in the cut-off grade calculations from the prior
mineral resource estimates as to what will be used in the upcoming
feasibility, as those assumptions remain to be
determined.
Updated Mineral
Resource Metrics
-
38 new drill hole
intersections through the Main and Esso deposits utilized to update
the new mineral resource calculation (3 at Esso, 35 at
Main);
-
2018 drilling successfully
delineated additional mineral resources along the down-dip edge of
Main, which remains open to further expansion;
and
-
Drilling defined a large
contiguous body of Measured resources at Main (Figure
1).
“The definition of an
updated, robust and larger resource estimate is a significant
milestone for the Company”, stated Rob Duncan, COO for Kutcho
Copper. “Based on new drill hole data and an independent mineral
resource estimation at Kutcho, we have expanded the mineral
resources at Kutcho and demonstrated potential for further reserve
growth in the upcoming Feasibility Study.”

Targets
High Priority Near
Resource Targets
Four excellent
targets exist on the Kutcho project that are located between, below
or along strike from existing mineral resources (Figure
1). These targets represent high probability drill areas
that could result in significant accretive value to the
project;
-
The Main-Sumac
Gap identifies a 400 m by 380m
panel between the Main and Sumac lenses that is untested by
drilling. A conductive geophysical anomaly coincides with the area
and is 360 m long. K003, the most eastern hole to intersect the
Sumac lens and located on the western margin of the gap returned
5.12 m of 1.29% Cu, 0.49% Zn and 7 g/t
Ag.
-
Open Down
Dip: Significant portions of all
three lenses remain open down dip outside of current resources
including over 36% of Main, 50% of Esso and 100% of
Sumac.
-
The Esso-West
Expansion target lies 300 m west
of the Esso deposit where 150m of a 1500 m long geophysical anomaly
has been drill tested. Drilling returned several mineralized
intercepts including 7.2 m of 2.0% Cu, 5.2% Zn and ~17 g/t Ag in
hole E094B3. There remains 300 m of untested Kutcho horizon between
hole E094B3 and Esso, along with an additional 1000 m of untested
horizon to the west of hole E094B3. (Off western edge of
map)
-
Footwall Zone
(FWZ) lies beneath the Main zone
and represents a stacked massive sulphide horizon that is open in
all directions. The last drill hole to the east and down dip
intersected 1.5 m of 3.54% Cu, 6.94% Zn, 316.9 g/t Ag and 1.47 g/t
Au in hole E057.
Mineral Resource
Estimation Methodology
Mineral
resource estimates are generated using a total of 362 drill holes
at the Main deposit, 118 drill holes at the Esso deposit, and 29
drill holes in the vicinity of the Sumac deposit. Drill holes are
collared from surface and extend to depths of 700m below surface in
some areas. Mineral resource estimates are derived from
three-dimensional block models with nominal block sizes measuring 5
x 2.5 x 5m (LxWxH). Resource estimates were generated using
drill hole sample assay results and the interpretation of
geological models which relate to the spatial distribution of
copper, zinc, gold and silver in the deposits. Interpolation
characteristics were defined based on the geology, drill hole
spacing, and geostatistical analysis of the data. The effects of
potentially anomalous high-grade sample data, composited to 1 metre
intervals, are controlled using both traditional top-cutting as
well as limiting the distance of influence during block grade
interpolation. Block grades are estimated using ordinary kriging
and have been validated using a combination of visual and
statistical methods to ensure they are appropriate representations
of the underlying sample data. Resources in the Measured category
are delineated with drill holes on a regular 25m pattern. Resources
in the Indicated category are delineated with holes on a nominal
50m pattern and Inferred class resources extend to a maximum
distance of 100m from a drill hole. It is assumed that the Kutcho
deposits would be mined using underground extraction methods. Based
on projected technical and economic parameters, the deposits form
consistent zones of mineralization, above a projected base case
cut-off threshold of 1.2%CuEq, that are considered to be amenable
to underground mining methods.
