NEWS RELEASE

CHAKANA COPPER INTERSECTS 52.0 METRES WITH 1.48% COPPER and 5.14 g/t

GOLD (5.35% CU EQ) AND 78.1 METRES WITH 1.36% COPPER AND 1.37 g/t GOLD

(3.00% CU EQ) IN BRECCIA PIPE 1

Vancouver, B.C., March 2, 2018 – Chakana Copper Co rp. (TSX-V: PERU; OTC:

CHKKF; FWB: 1ZX) (the “ Company ” or “ Chakana ”), is pleased to announce assays from

five additional step-out holes in Breccia Pipe 1 (Bx 1) at its Soledad copper-gold-silver project in

central Peru, optioned from Condor Resources Inc. The Soledad project (the “Project”) is located

35 km south of the Pierina mine in the prolific Mio cene metallogenic belt of Peru. These results

are a successful continuation of the drilling progr am that was initiated August 16, 2017, with the

results of the first twenty-seven drill holes relea sed previously (see: www.chakanacopper.com).

This Phase 1 drilling program is ongoing with a total of 10,629m drilled to date out of an original

planned program of 16,660m and is ahead of schedule and under budget.

“One of our initial goals in this drill program was to increase the grade profile from previous

explorers by drilling across the pipes to thoroughl y test the margin zones”, said President and

CEO David Kelley. “The results in these last five h oles from Bx 1 demonstrate the high-grade

nature of this pipe and the margin zone grades at t he edge of the pipe. Three of the five holes

have very high-grade margin zones such as 10.1m of 2.53% Cu, 7.72 g/t Au, and 26.0 g/t Ag in

hole SDH18-044. Hole SDH18-046 has high-grade margi n zones on both sides of the breccia

pipe with 8.0m of 3.33% Cu, 11.70 g/t Au, and 24.8 g/t Ag on the northeast margin, and 6m of

2.37% Cu, 3.12 g/t Au, and 139.9 g/t Ag on the sout hwest margin. These higher grades along the

margins may be due to a greater amount of open spac e between the fragments in the breccia

during pipe formation, and subsequent mineralizatio n by a hydrothermal fluid. Also included in

these results are significantly longer high-grade i ntercepts across the pipe including 52.0 metres

with 1.48% Cu, 5.14 g/t Au, and 60.2 g/t Ag and 78. 1 metres with 1.36% Cu, 1.37 g/t Au, and

87.2 g/t Ag.”

* Cu_eq and Au_eq values were calculated using copper, gold, and silver. Metal prices utilized for the calculations are Cu –

US$2.90/lb, Au – US$1,300/oz, and Ag – US$17/oz. No adjustments were made for recovery as the project is an early stage

exploration project and metallurgical data to allow for estimation of recoveries are not yet available. The formulas utilized to

calculate equivalent values are Cu_eq (%) = Cu% + (Au g/t * 0.6556) + (Ag g/t * 0.00857) and Au_eq (g/t) = Au g/t + (Cu% *

1.5296) + (Ag g/t * 0.01307). Assays for zinc and lead are not used in the metal equivalent calculations.

The true widths of the mineralized intervals report ed in this release are difficult to ascertain and

additional drilling will be required to constrain the geometry of the mineralized zones.

Exploration Update

A total of 9 mineralized breccia pipes have been id entified by mapping on the Project thus far.

The pipes form a cluster within an area of four-squ are kilometers and are spaced between 175m

to 625m apart with vertical relief between the pipes of over 500m.

The focus of the drilling program is to determine t he economic potential of several of the quartz-

tourmaline-sulfide breccia pipes that crop out at surface. Phase 1 is directed toward pipes 1 and 5

(Bx 1 and Bx 5). Phase 2 will be an expanded drill program proposed under a Semi-detailed

Environmental Impact Assessment permit (EIA-SD) tha t was submitted for review to the

Ministry of Energy and Mines on December 29, 2017. Phase 2 will allow for additional drill

platform locations and more drill holes to test sev eral other pipes and targets identified on the

Project. Based on detailed mapping, Bx 1 has a surf ace diameter of 40m and Bx 5 of 50m.

Mineralization is open at depth in both pipes based on previous drilling. Current drilling is

designed to determine the geometry (volume) and gra de of the breccia hosted mineralization.

Tourmaline breccia pipes can have diameters that increase at depth, and often have higher grades

at the margins of the pipe, interpreted to result f rom higher permeability of the breccia. Drilling

at the Project is designed to test this in each pip e from surface to 400m depth based on: 1)

drilling from a central platform at various azimuth s and dip angles to penetrate the margin of the

breccia throughout its vertical extent; and 2) from platforms outside the pipe to drill across the

breccia body. The five holes from Bx 1 reported her e were drilled from a step-out platform 80m

- 3 -

northeast of the breccia pipe. Mineralized intercep ts will vary in length due to the shape of the

breccia body and the orientation of the drill hole (see Figure 2). For example, shallow holes

drilled near the perimeter of the pipe may have sho rter intercepts compared to steeper holes.

Nonetheless, all holes that intersect mineralized breccia are important for constraining the overall

shape and grade of the breccia body. Once a suffici ent number of intercepts are obtained and

modelled, the overall geometry of the breccia body and the grade profile will become apparent.

Sampling and Analytical Procedures

Chakana follows rigorous sampling and analytical pr otocols that meet industry standards.

Samples for assay are stored in a secured area unti l transport in batches to the ALS facility in

Callao, Lima, Peru. Samples are processed under th e control of ALS with the samples including

certified reference materials, a coarse and finely- crushed blank and duplicates samples. All

samples are analyzed using the ME-MS41 procedure in order to obtain a comprehensive multi-

element overview of the geochemistry. Gold is analy zed by ME-MS41 (considered to be least

reliable), AA24 (higher precision) and GRA22 when v alues exceed 10 g/t. Over limit silver,

copper, lead and zinc is analyzed using the OG-46 procedures.

Additional information concerning the Project is av ailable in a technical report prepared in

accordance with National Instrument 43-101 made ava ilable on Chakana’s SEDAR profile at
