Chakana Reports 15.2 Metres of 2.1% Copper At Paloma East – Soledad Project, Peru
Within 172.7 Metres of 0.31 g/t Gold, 0.34% Copper, and 13.1 g/t Silver From Surface
Vancouver, B.C., September 17, 2020 – Chakana Copper Corp. (TSX-V: PERU; OTCQB: CHKKF; FRA: 1ZX) (the “Company” or “Chakana”), is pleased to provide drill results from the first three of five drill holes completed at the Paloma East target within the expanded Soledad Project in Ancash, Peru. These results are part of the Phase 3 drill program, a fully funded 15,000 metre drill program that started August 15, 2020. Phase 3 is testing a tight cluster of high-grade, gold-enriched tourmaline breccia pipe targets within the high-priority Paloma area and will then continue onto the Huancarama breccia complex (Fig. 1).
Mineralized intervals from Paloma East thus far include:

* 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).
Significant zones of mineralization were encountered in all three holes. Gold enrichment is noted in the top of holes SDH20-133 and SDH20-135, with intercepts of 7.5 metres with 1.55 g/t gold and 58.9 g/t silver from 18.5 metres depth, and 9.05 metres with 1.57 g/t gold and 15.6 g/t silver from 14.05 metres depth, respectively. Longer intervals of moderate grade mineralization are evident; in the case of SDH20-135, 172.7 metres with 0.31 g/t gold, 0.34 % copper and 13.2 g/t silver (1.00 g/t gold equivalent) was intersected from surface. Assays results for SDH20-136 and SDH20-137 are pending.
Phase 3 Drill Program Update – Paloma Target Area
The Paloma target area consists of two established outcropping breccia pipes, Paloma East and Paloma West (Fig. 2). Previous surface rock sampling confirmed strong anomalous gold concentrations in both the targeted breccia pipes as well as within several scattered small exposures of breccia and vein-like structures in the Paloma area. The Paloma East target is interpreted as the very top of a breccia pipe with a footprint at surface of 25 metres in diameter. All five holes completed at the Paloma East target (totaling 1,345 metres) have encountered visually mineralized tourmaline breccia. An additional hole is currently in progress testing the south-southwest margin of the Paloma East breccia pipe.
Based on modeling of the first four holes drilled to the northwest and northeast (holes SDH20-133 to SDH20-136), the Paloma East breccia pipe appeared to increase in diameter from 25 metres at surface to approximately 50 metres at 150 metres depth (Fig. 3). A fifth hole (SDH20-137) was drilled to the southwest at -75 degrees to again locate the margin of the breccia, anticipated to occur at approximately 170 metres depth. Except for a few internal blocks of wall rock, the drill hole intercepted tourmaline breccia from 14.75 metres to 627 metres depth, 530 metres below surface (Fig. 2). The extent of breccia spans the entire distance between the downward projections of Paloma East and of Paloma West targets at depth, equaling a horizontal distance of approximately 150 metres. Hole SDH20-137 exited breccia at 627 metres and ended in granodiorite with quartz-sericite-tourmaline alteration and trace pyrite-chalcopyrite. Notably, a significant amount of breccia with abundant pyrite mineralization was intersected in the lower part of this drill hole. This hole has confirmed a much more expansive breccia system than previously known, revealing a much larger area to explore in all directions.
David Kelley, President and CEO commented,
Assay results from the first three drill holes are very encouraging, continuing the trend of high-grade mineralization hosted in tourmaline breccia, within long runs of moderate grade mineralization as reported in other breccia pipes. We expected to find breccia beneath Paloma East and Paloma West in pipe-like mineralized bodies, however, drilling indicates that sulfide-rich tourmaline breccia extends beneath the two outcropping breccia pipes at depth for an impressive 150 metres of strike length horizontally. As there is little outcrop in this area, brecciation on the property may be much more extensive than previously thought. We look forward to sharing the assay results from additional drill holes in the near future.
About Chakana Copper
Chakana Copper Corp is a Canadian-based minerals exploration company that is currently advancing the high-grade gold-copper-silver Soledad Project located in the Ancash region of Peru, a highly favorable mining jurisdiction with supportive communities. The Soledad Project consists of high-grade gold-copper-silver mineralization hosted in tourmaline breccia pipes. A total of 31,641 metres of drilling has been completed to-date, testing eight (8) of twenty-three (23) confirmed breccia pipes with more than 92 total targets. Chakana’s investors are uniquely positioned as the Soledad Project provides exposure to several metals including copper, gold, and silver. For more information on the Soledad project, please visit the website at www.chakanacopper.com.
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 by AA24. 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.
