Vancouver, British Columbia--(Newsfile Corp. - March 3, 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 Huancarama Breccia Complex, within the Soledad Project in Ancash, Peru (Fig. 1). One hole (SDH20-165) was designed to test beneath the exposed H4 breccia, and a second hole (SDH20-166) was designed to explore a deeper extent of the Huancarama East breccia discovery (see figure 2, and news releases dated January 12, 25, and February 9, 2021). Since initiating drilling at Huancarama in late October 2020, thirty HQ diamond core holes have been completed.
Mineralized intervals from two additional holes at Huancarama include:
|DDH #||From - To (m)||Core Length (m)||Au|
* 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).
Both drill holes intercepted high-grade intervals (Figs. 2 and 3). Hole SDH20-165 was set up southeast of the H4 surface breccia and drilled to the northwest encountering a high-grade breccia interval of 0.27 g/t Au, 1.63% Cu, and 305.0 g/t Ag (4.41% Cu-eq) over 6.5m starting at 79m depth. This intercept is believed to be related to the H4 breccia exposed at surface and is interpreted to be a breccia dike, related to a larger, adjacent breccia body. Breccia dikes adjacent to larger breccia pipes are a common feature of the breccia pipes at Soledad.
Hole SDH20-166 was set up on the east side of the main Huancarama East breccia pipe and drilled steeply across the pipe in a west-northwest direction. This hole entered the main breccia body at 107.2m down hole (102m below surface) and exited the breccia pipe on the northwest side at 308.2m depth (290m below surface). A continuous mineralized interval of 175.6m with 0.42 g/t Au, 0.48% Cu, and 35.9 g/t Ag (1.06% Cu-eq) was encountered starting at 132.0m. Within this interval, a high-grade zone of 1.21 g/t Au, 1.35% Cu, and 95.6 g/t Ag (2.96% Cu-eq) over 29.0m starting at 132.0m depth was also encountered. Two additional breccia intercepts, also interpreted as breccia dikes related to the Huancarama East breccia pipe, were encountered at 402.7m and 483.4m depth, with the breccia pipe open at depth. Examples of mineralized drill core from these holes are shown in Figure 4.
David Kelley, President and CEO, commented, "Hole SDH20-166 was successful in increasing the Huancarama East breccia pipe to a depth of 290m below surface with mineralization open at depth. We had previously established mineralization starting at surface and continuing to a depth of approximately 225m depth. As we have seen in the other breccia pipe discoveries, these pipes are vertically extensive, and all are still open at depth. The high-grade intercept of 29.0m with 1.21 g/t Au, 1.35% Cu, and 95.6 g/t Ag is particularly noteworthy as it provides additional confirmation of the high-grade potential of this new discovery and is consistent with intercepts recently reported. It is also encouraging to encounter high-grade mineralization in the first hole drilled around H4 on the western side of the complex. As we have seen in drilling other breccia pipes at Soledad, these high-grade intercepts are normally related to adjacent larger mineralized breccia bodies. More drilling is warranted on the western side of Huancarama. and drilling is ongoing at both Huancarama and Paloma with two drill rigs; we look forward to reporting additional results soon."
Huancarama Target Area and the Current 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 horizontally (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 recently expanded 2021 drill program of 26,000m that is fully funded from the Company's current treasury of $9.3M. Combined with the drilling in 2020 that started last August, a total of approximately 32,000m is anticipated through 2021. Of this, 6,634m have been reported in 34 drill holes. For the 26,000m of drilling planned in 2021, the Company will complete 16,000m of resource definition drilling, and 10,000m of exploration drilling testing new targets. This drill program and additional targets will be integral to the publication of a maiden resource in 2021.
The Company announces that its second tranche of financing announced February 10, 2021 has been extended in order to facilitate the receipt of funds already committed over the next few days.
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 39,098 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 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.
David Kelley, an officer and a director of Chakana, and a Qualified Person as defined by NI 43-101, reviewed and approved the technical information in this news release.
