Canada Silver Cobalt intersects 30,416 g/t silver over 0.42m in New Vein at Castle East

Aug 10, 2021

"These three intercepts provide us with two newly discovered, high-grade vein systems," said Matt Halliday, P.Geo., President, and COO. 

Canada Silver Cobalt Works Inc. has announced a continued expansion at Castle East with three new, high-grade intersections with silver grades of 30,416.91 g/t over 0.42m, 7,328.47 g/t over 0.38m, 1,883.21 g/t Ag over 0.42m, and with gold equivalent grades of 425.94 g/t, 102.62 g/t, 26.37 g/t AuEq respectively. 

Drilling Highlights:

  • Hole CS-21-61 with an exceptional intercept grading 30,416.91 g/tonne silver (887.31 oz/ton Ag) over 0.42m at a downhole depth of 449.55-449.97m with a gold equivalent grade of 425.94 g/tonne Au (12.42 oz/ton Au). This incredibly mineralized vein is located 35m south from the Robinson Zone discovery hole CA-11-08, and 60m west of Big Silver discovery hole CS-20-39. The Company currently believes this intercept belongs to a brand-new vein structure, independent from both the Robinson Zone and the Big Silver vein.
  • The first intercept in hole CS-21-65 contains 7,328.47 g/tonne silver (213.77 oz/ton Ag) over 0.38m at a downhole depth of 254.03-254.41m with a gold equivalent grade of 102.62 g/tonne Au (2.99 oz/ton Au). This intercept is located 230m below the surface, 70m to the south and 220m above the Robinson Zone. To date, this is the closest high-grade intercept to surface and is located within Archean lithologies.
  • The second intercept in hole CS-21-65 contains 1,883.21 g/tonne silver (54.93 oz/ton Ag) over 0.42m at a downhole depth of 421-421.42m with a gold equivalent grade of 26.37 g/tonne Au(0.77 oz/ton Au). 

"We continue to have excellent results from the 60,000m drill program at Castle East, with 40,000m completed to date. There is now a total of eight distinct high-grade veins to be included in the Q1 2022 resource update. The initial estimate in May 2020 for Castle East (see below) was based solely on the Robinson Zone vein system but recent drilling has discovered an even higher-grade vein (Big Silver grading 89,853 g/t Ag over 0.30m) in addition to six other new vein structures, and our exploration program has expanded the overall area to be included in the resource estimate," said Matt Halliday, P.Geo., President, and COO. 

The geological implications of these veins are threefold: First, the addition of another exceptionally high-grade vein in CS-21-61 puts us that much closer to significant expansion of the resource at Castle East. Second, the high-grade silver vein in CS-21-65 (that is 230m below the surface) confirms the existence of much shallower silver mineralization at Castle East. Third, it greatly expands the potential for silver mineralization to occur across the entire property because it occurs within the Archean lithologies. Most of our high-grade or notable veins are located within the younger Nipissing Diabase sill which is intruding into the older Archean rocks. This means that it is possible for further silver mineralization to occur in the same Archean lithologies both above and below the Nipissing Diabase, similarly to the vein found in CS-21-65 that is located above the intrusion. As a further proof of concept, both the Beaver Mine and Temiskaming Mine had significant production both above and below the Nipissing diabase intrusion. This ultimately expands the potential horizon within the property and is very encouraging for future exploration.
