Copper Standard Confirms Presence of Porphyry Copper-Gold System and Drills 118 m @ 0.68 g/t Au from Surface at Its Colpayoc Property

12.08.2024  |  Newsfile

Vancouver, August 12, 2024 - Copper Standard Resources Inc. (CSE: CSR) ("Copper Standard" or the "Company") is pleased to announce the results from the first 10 holes of drilling at the Colpayoc copper-gold exploration project in the Yanacocha Mining District in Cajamarca, Peru. The Company has completed 1,926.1 meters (6,319 feet) of core drilling confirming the presence of a porphyry copper-gold system and verifying and expanding the oxide and mixed oxide gold mineralization in the Daylight Porphyry target, one of four targets on the property. Drilling intersected a series of nested porphyry intrusions carrying variable amounts of gold and copper. Significant drill results which may contribute to increasing the oxide gold resource include:

  • DH COLP24 - 01: 109.0 meters (357 feet) @ 0.76 g/t Au and 0.13% Cu from surface;
  • DH COLP24 - 03: 8.5 meters (27 feet) @ 5.11 g/t Au from 121.7 meters (399 feet);
  • DH COLP24 - 07A: 200.1 meters (656 feet) @ 0.52 g/t Au from surface to End of Hole;
    • Including: 118.0 meters (387 feet) @ 0.68 g/t Au and 0.11% Cu from surface;
  • DH COLP24 - 08: 138.0 meters (452 feet) @ 0.34 g/t Au from surface to End of Hole;
    • Including: 44.0 meters (144 feet) @ 0.54 g/t Au from 7.0 meters (22 feet); and
  • DH COLP24 - 09: 118.8 meters (389 feet) @ 0.46 g/t Au from surface to End of Hole.

Drill holes COLP24 01, 07, and 07A intersected broad zones of mineralization, expanding the mineralized zone at depth and demonstrating that the system remains open along trend to the south towards the Montura target, and at depth. Drill hole COLP24 07A was mineralized along its entire length. Drill holes COLP24 08 and 09 were drilled on the western side of the Daylight Porphyry target and expanded the known mineralization and showed that the western side of the resource is open to the west, north, and south. Drill holes COLP24 - 02, 03, 05, and 06 were drilled on the east side of the resource and show limited expansion but mineralization remains open to the north towards the Crater target, west, and south. See Figure 1 for the summary of 2024 drill hole locations and Figure 2 for the summary of significant gold and copper intercepts. The laboratory turnaround of drill-hole assays has been significantly longer than usual which made it difficult for the Company to plan its additional drill-hole locations. As a result, the Company's Phase I drilling program has been paused while the Company prepares for additional geophysical surveys discussed in more detail below.

The copper and gold mineralization occurs within three porphyry intrusions which confirms the potential for larger primary copper-gold porphyry deposits, particularly in the untested targets of Montura, Crater, and Rayo Grande. These drill results and the distribution of mineralization suggests that a systematic deep-penetrating induced polarization ("IP") survey will be useful to identify extensions of the known mineralization, look for underlying porphyry copper-gold systems, and to plan drilling for the Montura, Rayo Grande, and Crater targets (see Figure 3) in the area surrounding the Daylight Porphyry Zone. An IP survey is currently underway to optimize the targets for the Company's proposed Phase II drilling program.

Andy Swarthout, Chairman, commented, "The Phase I drilling advanced the expansion of the oxide gold mineralization at the Daylight target and has provided strong support that primary copper-gold porphyry systems underlie the oxide gold mineralization. To date, the presence of multiple intrusive phases, mineralized hydrothermal breccias, and intense quartz-sulfide stockwork veining indicates that the multiple, untested targets have excellent potential for both the discovery of additional oxide gold and large porphyry copper-gold deposits within our mineral concessions. We look forward to the IP survey results which we expect will provide more certainty for targeting our proposed Phase II drilling program."

The National Instrument 43-101 Technical Report on the Colpayoc Project entitled "Technical Report on the Colpayoc Gold Property, Department of Cajamarca, Peru", prepared by Steven L. Park and dated effective date December 20, 2021 (the "Technical Report") can be found on the Copper Standard website at https://copperstandard.com or on SEDAR+ at www.sedarplus.ca.

Note: For additional information regarding the inferred mineral resource estimate, please refer to the Technical Report. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve. Inferred mineral resources are considered too geologically speculative to have mining and economic considerations applied to them that would enable them to be categorized as mineral reserves.

Quality Assurance and Quality Control Statement

The Company's 2024 drill program used conventional contracted core drilling with mainly HQ and/or NQ size. The core was logged and marked for sampling and assaying by Copper Standard Peru-based geologists. Samples, typically 1.0-2.0 meters in length were sawn in half using a diamond core saw and one-half of the core was placed in sample bags and tagged with unique sample numbers, while the remaining half was kept in the core box for storage. Each bagged core sample was shipped to ALS Laboratory in Lima, Peru. Samples were dried, crushed and pulverized to >80% passing -200 mesh. Gold was analyzed by fire assay (30 g) with an AA (atomic absorption) finish (method Au-AA23) with detection limits of 0.005 g/t gold. Samples containing greater than 10.0 g/t gold are analyzed by fire assay with a gravimetric finish (method Au-GRA21). Multielement analyses were analyzed with ICP-MS following a four-acid digestion (method ME-MS61) and samples containing >1.0% copper are analyzed via method Cu-OG62. Strict sampling and QA/QC protocols are followed, and assay integrity is monitored internally with a quality control program including the insertion of gold standards and blanks in the sample stream on a regular basis.
