Vancouver, British Columbia--(Newsfile Corp. - January 25, 2021) - Chakana Copper Corp. (TSXV: PERU) (OTCQB: CHKKF) (FSE: 1ZX) (the"Company"or"Chakana"), is pleased to release results for two additional drill holes from the recently-announced discovery at the Huancarama Breccia Complex, within the Soledad Project in Ancash, Peru (Fig. 1). The holes complement the initial eight holes that were published on January 12, 2021. Drilling at Huancarama is ongoing where eighteen HQ diamond core holes have been completed thus far.
Mineralized intervals from two additional holes at Huancarama 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).
Holes SDH20-161 and SDH20-162 were drilled to the northeast from the south side of the breccia complex (Figures 2 and 3). Both holes intersected continuous mineralization across the breccia body previously defined by the first eight holes and an historical tunnel that transects the breccia. Hole SDH20-161 was oriented directly beneath a collapse zone and intersected 107m with 0.28 g/t Au, 0.42% Cu, and 33.7 g/t Ag (1.36 g/t Au-eq) starting at 86m; hole SDH20-162, drilled beneath the west edge of the collapse zone, encountered 120.4m with 0.51 g/t Au, 0.83% Cu, and 34.6 g/t Ag (3.71 g/t Au-eq) from 101.3m depth, including 72.2m with 0.79 g/t Au, 1.32% Cu, and 46.9 g/t Ag (3.42 g/t Au-eq) from 101.3m. A higher-grade zone of 30.0m with 1.44 g/t Au, 2.55% Cu, and 88.2 g/t Ag (6.50 g/t Au-eq) starting at 109.0m depth occurs within this interval. Examples of mineralized drill core from these holes are shown in Figure 4.
David Kelley, President and CEO commented, "These two holes were drilled from a new platform on the south side of the Huancarama Breccia Complex and confirm the breccia geometry previously reported with approximate horizontal dimensions of 100m by 50m, one of the largest breccias we have discovered to date at Soledad. The mineralized breccia crops out at surface and extends to a vertical depth of approximately 225m below surface and is open at depth. The results demonstrate good continuity of mineralization within the breccia with excellent grades. The high-grade zone within hole SDH20-162 shows copper sulfide-cemented breccia and the late copper sulfide replacement process that we have seen in several other high grade breccia pipes at Soledad. Drilling is ongoing at Huancarama and we look forward to reporting additional drill results in the near future."
Huancarama Target Area and the Phase 3b Drill Program
The Huancarama Breccia Complex is located 300m south of and 400m above the deepest breccia intercept at Paloma. Within the complex there are five principal breccia bodies exposed at surface over approximately 200m (Fig. 5). There is a distinctive feature believed to be a collapse zone with dimensions of 50m by 30m. Unverified reports suggest that this may be due to small-scale mining. Two historic adits are in the complex, one trending north-northeast for 170m along the western side of H1 (Fig. 2), and a second shorter adit of 21m at H2. Surface sampling from the breccia bodies and channel sampling of the adits yielded strongly anomalous gold results (see news release dated November 19, 2019). In addition to several targets within the complex, numerous additional targets exist in the Huancarama and Paloma area.
Results reported here are part of the ongoing Phase 3b drill program, which is fully funded from the Company's current treasury and is anticipated to see 15,000 metres completed. Phase 3b is testing a cluster of high-grade, gold-enriched tourmaline breccia pipe targets within the Paloma and Huancarama target areas. Thirty holes have now been reported from the Phase 3b program.
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 36,185 metres of drilling has been completed to-date, testing ten (10) of twenty-three (23) confirmed breccia pipes. The exploration team has identified 92 targets in total on the project, confirming that Soledad is well endowed and has strong exploration potential. 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.
