Vancouver, B.C., March 4th, 2019. 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.
Kutcho Project - Estimate of Mineral Resources
Measured + Indicated
Combined – All Deposits
Measured + Indicated
- 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.
- Estimate assumes Mining (underground) US $34.00/t, Processing US $18.00/t, US G&A $10/t, copper price US $3.00/lb, zinc price US $1.25/t, gold price US $1350/oz, silver price US $17.00/oz, copper payable recovery 82.5%, zinc payable recovery 72.5%, silver payable recovery 45%, gold payable recovery 40%
- 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."

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.
