Chakana Intersects 32 Metres With 2.99 g/t Gold, 1.52% Copper, And 33.0 g/t Silver (5.75 g/t Au_EQ, 3.76% Cu_EQ) Within 144 M...

Chakana Copper Corp. (TSX-V: PERU; OTCQB: CHKKF; FRA:
1ZX) (the “
Company” or
“
Chakana”), is pleased to announce that drilling
has encountered an unexpected tabular body of mineralized breccia
in close proximity to Breccia Pipe 5 (Bx 5). The body is very well
mineralized, open and has important exploration implications to all
the targets at Soledad. These results are part of Chakana’s fully
funded 20,000m Phase 3 drill program at the Soledad
copper-gold-silver project in central Peru.
Bx 5 East Target
There are twenty-three confirmed outcropping
breccia pipes identified to date on the property (Fig. 1). Previous
drilling at Bx 5 had outlined a mineralized, east-plunging breccia
pipe to a depth of approximately 300m (see news release dated
February 22, 2018, November 13, 2018, and January 10, 2019). Bx 5
is situated at the intersection of east and north-northeast
trending structures. Two holes were drilled to test immediately
east and down-plunge of the known breccia pipe from a step-out
platform located 135m south-southeast from previous drilling at Bx
5 (Figs. 2 and 3). Both holes intersected long sections of
mineralized breccia in a body that extends east and north of the
known breccia pipe. These two holes returned 144m with 0.88 g/t Au,
0.88% Cu, and 13.6 g/t Ag in SDH19-126, and 172m with 0.29 g/t Au,
0.93% Cu, and 8.4 g/t Ag in SDH19-127. Important margin zone
mineralization was also encountered in each hole, where grades are
significantly higher. Assays are pending from a third hole
(SDH19-128) that was drilled into the zone from a platform to the
north (Fig. 3). Additional drilling is planned to follow this
high-grade zone to depth.
“This is a significant development in the
understanding of mineralization around Bx 5. The orientation of the
breccia zone plunges to the north and is open at depth. While
previous drill results on Bx 5 were favorable, this new zone has
higher grades and has mineralized margin zones, something we have
not seen since drilling at Bx 1. It may indicate that this new zone
is a separate blind breccia pipe that intersects the breccia pipe
that crops out at surface. Alternatively, we could be seeing zoning
to higher grade copper with depth,” said President and CEO David
Kelley. “These results indicate the importance of continued
drilling once a favorable structure has been discovered. Breccia
pipe mineralization at Soledad is zoned both vertically and
horizontally, blind pipes exist, and high-grade domains are
important,” added Kelley. Examples of mineralized breccias from
holes in this release are shown in Figures 4 and 5.

* 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). |
Reported mineralized intervals are not true
widths given the vertical nature of the breccia pipe and the steep
inclination of the holes.
Bx 6 In-Fill Drilling
Additional drilling was completed on Bx 6 to
further delineate the geometry of the breccia and to investigate
the grade distribution. Two holes were drilled near the surface
outcrop of the breccia to intersect the north margin, and four
holes were drilled from a step-out platform approximately 110m to
the south to further define the north margin of the upper breccia
at depth (Fig. 6 and 7). “These holes successfully demonstrated
that the north margin of the breccia pipe is expanding at depth,
which is consistent with our understanding of how these breccia
pipes form,” stated Kelley.

Target Testing
Four drill holes were completed in the Bx 3W
target in the north central part of the property (Fig. 1).
Significant breccia was encountered with quartz-tourmaline-pyrite
but without significant grades. Another hole was drilled to the
southeast in order to test a geophysical anomaly, encountering
sericite-pyrite-altered intrusive rocks without significant grades.
The relation of these altered intrusive rocks to the breccia
mineralization is unknown at this time.
About the Phase 3 Drill
Program
The Phase 3 drill program is planned for 20,000m
to test a variety of targets on the expanded property and to
complete additional definition drilling. Approximately 4,300m of
drilling has been completed since the start of the Phase 3 program.
Based on extensive surface exploration work completed since Phase 2
drilling, a total of 92 targets have been defined and ranked.
Targets are categorized as 1) outcropping breccia (n=45), 2)
inferred breccia based on breccia float, geochemistry or geophysics
(n=39); and 3) non-breccia or intrusive-hosted mineralization and
polymetallic vein occurrences (n=8). Of these targets, 23 are
tourmaline breccia pipes, and 12 others are areas possessing the
alteration characteristic of the halo proximal to known breccia
pipes. The strategy is to drill approximately 750m into each target
in accordance with permitting and ranking criteria to further
determine if closer-spaced drilling is justified.
Sampling and Analytical
Procedures
Chakana follows rigorous sampling and analytical
protocols that meet or exceed industry standards. Core samples are
stored in a secured area until transport in batches to the ALS
facility in Callao, Lima, Peru. Sample batches include certified
reference materials, blank, and duplicate samples that are then
processed under the control of ALS. All samples are analyzed using
the ME-MS41 (ICP technique that provides a comprehensive
multi-element overview of the rock geochemistry), while gold is
analyzed by AA24 and GRA22 when values exceed 10 g/t. Over limit
silver, copper, lead and zinc are analyzed using the OG-46
procedure. Soil samples are analyzed by 4-acid (ME-MS61) and for
gold by Fire Assay on a 30g sample (Au-ICP21).
Results of previous drilling and additional
information concerning the Project, including a technical report
prepared in accordance with National Instrument 43-101, are made
available on Chakana’s SEDAR profile at www.sedar.com.
