ON EXPLORATION

  • Silver Spruce Resources Inc., filed environmental permits with the Secretariat of Natural Resources and Environment (SEMARNAT) to drill at their the Diamante, Mezquite and Jackie projects in Sonora. Approvals from SEMARNAT are expected to be obtained by late March, 2022.
  • Canasil Resources Inc., provided a review of the results from its 2020-21 drill program on the Candy Vein at its Nora project. 13 drill holes were completed for a total of 3,296m to test the Candy vein over a strike distance of 500m and to a vertical depth of 250m below surface. All the holes encountered the mineralized vein with the highest true width x grade value on hole NRE-21-11 with 5.31 g/t Au and 336 g/t Ag (748 g/t AgEq) over a true width (TW) of 11.29m, giving a TW x grade value of 8,445 g/t AgEq x m. The drill results show that the Candy vein hosts consistently high grade gold and silver mineralization over appreciable widths. The Candy vein is known over 3km long but only 500m have been drill tested. Additionally, Canasil reported that systematic grid soil sampling over a 2km east-west and 3km north-south area covering the central zone of the project returned widespread silver, gold, copper, zinc and lead geochemical anomalies. “The gold and silver anomalies are particularly strong over the 3-Km strike extent of the Candy vein structure on the western side of the project area, as well as to the southwest and east of the Candy vein structure. A strong silver and gold anomaly also extends for 1.5 Km southwest from the location of the above high grade drill intercepts on the Candy vein and a breccia target has been identified to the south with potential for hosting bulk tonnage disseminated silver-gold mineralization”.
