Breccia 7: First Pass Drilling Confirms a Fourth Mineralized Breccia Pipe at Soledad
29 Juillet 2019 - 2:30PM
Chakana Copper Corp. (TSX-V: PERU; OTCQB: CHKKF; FRA:
1ZX) (the “
Company” or
“
Chakana”), is pleased to release the first drill
results from scout drilling on Breccia Pipe 7 (Bx 7) at the Soledad
copper-gold-silver project in central Peru. All four drill holes
intersected significant mineralization, including 31.0m with 0.68
g/t Au,
205.9 g/t Ag, and 0.23% Cu from 157m in
hole SDH19-111 and 35.0m with 0.80 g/t Au, 53.8 g/t Ag, 0.35% Cu
from surface in hole SDH19-114. This is the first time Bx 7 has
been drilled.
Bx 7 is located 340 metres northeast of Bx 1 and
is one of twenty-three outcropping breccia pipes identified to date
on the property (Fig. 1). Including Bx 7, only five of the
twenty-three breccia pipes have been drilled to date. The four
shallow holes reported here were designed to explore the uppermost
200m segment of Bx 7 (Figs. 2 and 3) and to provide some indication
of pipe geometry and grade distribution. Drill collars were located
outside of the breccia pipe within the wall rock that hosts the
breccia. All drill holes achieved the objective of intersecting the
pipe, defining contacts on opposite sides of the pipe.
“These initial scout drilling results are
excellent in that they confirm a fourth mineralized breccia pipe on
the property. Bx 7 appears to be more enriched in silver and gold
compared to copper although that could change with depth. It is
difficult to determine the geometry of the pipe with just four
drill holes, but we currently estimate the diameter between
40-50m,” said President and CEO David Kelley. “It is also
noteworthy that hole SDH19-111 intersected 12.6m of mineralized
breccia 15m north of the main breccia body (Fig. 3). This is
reminiscent of the blind breccia body encountered in drilling Bx 1
(see news release dated June 26, 2018). Several additional holes
will be drilled under SDH19-111 after the scout drilling of the
Phase 3 drill program is nearing completion,” added Kelley.
Examples of mineralized breccias from holes in this release are
shown in Figures 4 and 5.
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. 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 on the basis of
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. The drill rig
will move to other targets for initial scout drilling and Bx 6 for
additional drilling on the upper breccia.

* 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.
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.
