Chakana Reports Channel Sampling At Huancarama
VANCOUVER, Nov. 19, 2019 - Chakana Copper Corp. (TSX-V: PERU; OTCQB: CHKKF; FRA: 1ZX) (the “Company” or “Chakana”), is pleased to provide new surface and subsurface assay results from the Huancarama Breccia Complex, a general exploration update, and additional reconnaissance drilling results for the Soledad project in Peru.
Huancarama Channel Sampling
The Huancarama Breccia Complex (HBC) is a large exposure of mineralized tourmaline breccia within the main Soledad cluster of breccia pipes (Fig. 1). Several breccia bodies are exposed over a width of approximately 200m. Previous surface sampling and continuous underground channel sampling along a 170m long adit revealed strong gold and silver values (Fig. 2; also see news release dated May 23, 2018). Copper values are generally low due to the oxidized nature of the surface samples. Recent detailed mapping identified a 15m-long adit into one of the smaller breccia bodies (HBx2). Twenty-one metres of continuous channel samples on one metre intervals were collected from the adit and exposure of breccia outside the adit (Figs. 3 and 4). This continuous channel sample of 21 metres averaged 2.52 g/t Au and 100.4 g/t Ag. The estimated true width of the breccia from this sampling is 14.3m. Huancarama will be drill tested during the next campaign when final drilling permits are obtained.
“The recent sampling provides additional confirmation of the potential of the Huancarama breccias,” said President and CEO David Kelley. “These breccias and the Paloma East and West breccias are examples of the numerous high priority targets we have yet to drill,” added Kelley.
Exploration Program Update
A total of 5,717m of drilling has been completed in the Phase 3 drill program that began in June, 2019. The drilling has been successful in
- confirming mineralization in Bx 7 that requires additional drilling,
- in-fill drilling on Bx 6 that we expect will contribute to an inferred resource in the upper levels of breccia,
- extending mineralization in Bx 5 at depth to the east and north with significant copper grades encountered, and
- confirming that the Corral breccias are mineralized and require additional drilling from more optimal platform locations when permits are obtained.
In addition, Bx 3W is mineralized with pyrite in a well-developed tourmaline breccia but lacks significant grade to the depths tested. This may be a function of zoning with the potential for copper at depth.
Continued permitting delays have limited our ability to drill in the Huancarama and Paloma areas. While we have successfully completed drill testing on other priority targets to date, we have decided to temporarily suspend drilling until the permits are obtained for these higher priority targets. This will ensure that we have the capital available to drill high priority drill targets as soon as the proper permits are obtained. The recent dismissal of Congress by the current administration and subsequent temporary replacement of Cabinet positions until elections are held has caused additional disruptions in the permitting process. We remain persistent in our approach to obtain the necessary permit approvals that will allow the restart of drilling.
Additional Drill Results
Assay results are provided for two additional holes in Bx 5 East, two holes in the Corral Breccia, and one hole testing a target southeast of Bx 1. The two holes in Bx 5 East were drilled from new platform locations to provide better control on the geometry of the breccia (Fig. 5). The first hole at the Corral target intersected two mineralized breccia bodies, Corral Bx 1 and Corral Bx 2. The second hole intersected Corral Bx 1. Both holes were drilled downhill at shallow angles due the restricted access pending permits closer to the breccia bodies. Recoveries in the mineralized breccia were poor due to the shallow angles and broken nature of the rock. One exploration hole southeast of Bx 1 was drilled beneath a mineralized structure. Only a narrow interval of mineralization was encountered.
Mineralized intervals from Bx 5 East include:

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.
