Chakana Reports High-Grade Intersects
125.0m of 0.63 g/t Au, 0.54% Cu, and 55.7 g/t Ag (1.43% Cu-eq); Including 15.0m of 2.29 g/t Au, 1.27% Cu, and 248.6 g/t Ag (4.89% Cu-eq) at Huancarama
Vancouver, British Columbia–(Newsfile Corp. – April 28, 2021) – Chakana Copper Corp. (TSXV: PERU) (OTCQB: CHKKF) (FSE: 1ZX) (the “Company“ or “Chakana“), is pleased to provide recently received drill results from eight exploration holes from Huancarama totaling 1,522.1m (Table 1) and five resource drill holes from Paloma East totaling 1,455.15m (Table 2). Drilling continues as part of a fully-funded 26,000m exploration and resource drilling program (Fig. 1).
David Kelley, President and CEO, commented, “It is great to see these strong results from both new exploration drilling and definition drilling. At Huancarama East, we are clearly defining a sizeable zone of copper-gold-silver mineralization that should feature prominently in our resource estimation plans. At Huancarama West, the exploration drilling continues to define shapes and continuity, while Paloma East has impressive significant near-surface mineralization and long runs of mineralization, including 163.9m of 0.42 g/t Au, 0.33% Cu, and 11.7 g/t Ag from surface in tourmaline breccia that is open at depth. The drill program continues to run smoothly with effective COVID protocols in place.”

* 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).
Eight holes were drilled in the Huancarama Breccia Complex – seven holes were collared on the western side of the complex, and one hole was collared on the far eastern side (Figs. 2 and 3). Hole SDH21-176 started on the western side of the complex intercepting two breccias, then continued across to the east-southeast of the complex with continuous breccia encountered from 199.0 to 324.0m depth. Hole SDG21-187 was drilled to the southwest and intersected two continuous zones from 167.2m to 217.0m, and 268.0m to 312.85m depth. Given the grade and continuity of mineralization in the Huancarama East breccia pipe, resource drilling has been focused in this area. Examples of mineralized drill core from these holes are shown in Figure 6.

At Paloma East, five holes were drilled as part of the resource drilling program (Figs. 4 and 5). Three holes were set up on the west side of the breccia pipe and drilled to the east, and two holes were set up on the northeast side and drilled to the southwest. Shallow mineralization was encountered in all five holes. Hole SDH21-188 intersected 163.9m of mineralized breccia starting at surface, then continued to the southwest where strongly pyritic breccia was encountered at depth. Examples of mineralized drill core from these holes are shown in Figure 7. Additional infill drilling is being planned for the shallow mineralized zone at Paloma East.
2021 Resource and Exploration Drill Program
Results reported here are part of the fully funded 2021 drill program of 26,000m. Combined with the drilling in the second half of 2020 approximately 32,000m is anticipated through 2021. Of this, 11,062.5m have been reported in 56 drill holes for the Paloma and Huancarama areas. For the 26,000m of drilling planned in 2021, the Company will complete approximately 16,000m of resource definition drilling. This drill program will be integral to the publication of a maiden resource in 2021.
Additionally, 10,000m of exploration drilling is planned for 2021. This will focus on new targets located in the northern portion of the project that have not been drilled previously but are strategic to any eventual development at Soledad. A strategic review of exploration targets is underway and plans are currently being finalized with an update to shareholders to follow.
About Chakana Copper
Chakana Copper Corp is a Canadian-based minerals exploration company that is currently advancing the 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 45,061 metres of drilling has been completed to date, testing ten (10) of twenty-three (23) confirmed breccia pipes. The exploration team has identified 110 targets in total on the project, confirming that Soledad is a large, well-endowed mineral system with strong exploration upside. 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.
