Soledad Project Highlights Include:
Chakana Copper Corp. (TSX-V: PERU) (OTCQB: CHKKF) (FSE: 1ZX) is pleased to provide results from the final seven resource definition holes drilled in Bx 1 totaling 2,474.65m from the Soledad project, Ancash, Peru (Table 1). Drilling continues as part of a fully funded 26,000m exploration and resource drilling program planned for 2021 (Fig. 1). These results will increase confidence in the initial resource estimate, anticipated at the end of 2021.
“Results for the final seven resource definition holes for Bx 1 are excellent as expected and consistent with previous drill results. These results, combined with previous drilling at Bx 1, will be part of the initial resource estimate that will also include Bx 5, Bx 6, Paloma East, Paloma West, and Huancarama. We look forward to releasing additional drill results from our ongoing drill program and are committed to having the initial resource estimate out by the end of the year,” stated President and CEO David Kelley.

* 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).
There are two breccia pipes at Bx 1, the Main Zone that crops out at surface, and the North Zone that is 40 metres north of the Main Zone and begins 125m below surface (Figs. 3 and 4). Drill holes in this release were designed to fill in gaps in previous drilling to contribute to the initial resource estimate. Three holes were drilled to the north from a central platform where the Main Zone crops out at surface. These holes cut the Main Zone and the North Zone. Four additional holes were drilled to the southwest from a platform located northeast of Bx 1 and were designed to fill in gaps on the southwest margin of the Main Zone.
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 the end of 2021. Of this, 18,414m have been reported to date in 83 drill holes. Additional resource definition drill results for Bx 5 and Huancarama are pending. In addition, new targets located in the northern half of the project that have not been drilled previously but are strategic to any eventual development at Soledad will be tested. Exploration targets have been ranked based on their technical merit, access, and logistics.
Two different types of geophysical surveys are being tested to identify new breccia pipe targets and help refine the ranking of our existing 110 targets identified to date. Orientation surveys based on gradient array induced polarization and 3D induced polarization are underway over the known and well understood mineralized breccia pipes. Once the parameters of the surveys are optimized, the surveys will be completed throughout the 12-km2 footprint of the Soledad mineral system where tourmaline breccias are known. These techniques will improve our understanding of the structural controls on fertile corridors that host the breccia pipes, help identify additional breccia pipes that may not come to surface, and refine the existing targets that we have.
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 copper-gold-silver mineralization hosted in tourmaline breccia pipes. A total of 60,225 metres in 259 diamond core holes for exploration and resource definition drilling have been completed since 2017, testing 15 of 110 total exploration targets, 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 base and precious.
Figure 1 – View looking north showing outcropping breccia pipes and occurrences within the northern Soledad cluster. Pipes that have been drilled in previous campaigns are shown in red. Breccia pipes shown in green are new discoveries made in 2020. Other pipes and occurrences remain to be tested by drilling. Additional breccia pipes occur on the south half of the property and are not shown here.
