Nord Precious Metals Hits 2,848 g/t Silver Over 6.65m, Extending Castle East's Robinson Zone

The Robinson Zone at Castle East has delivered some of the highest silver grades reported in the Cobalt-Gowganda district this drilling cycle, and Nord Precious Metals Mining Inc. has now extended it further with a wedge hole drilled 10 metres away from the parent intercept.

Hole CS-21-73W1 returned 2,848 g/t Ag over 6.65m — 18,939 gram-metres — including a 0.30m core of 61,389 g/t Ag (1,790.8 oz/ton). Cobalt, nickel, and copper accompanied the silver throughout the mineralized envelope, with the 0.30m high-grade interval carrying 2.44% Co, 0.24% Ni, and 0.09% Cu. The structural setting is a quartz vein system characteristic of the five-element silver-cobalt veins that defined the historic Cobalt camp.

"These assays confirm what the core showed us in February: Castle East continues to deliver significantly strong silver values in the style that defined this district, with high-grade silver over 0.30 metres inside a 6.65-metre mineralized envelope and critical minerals carried right alongside it," said Frank J. Basa, President and CEO of Nord Precious Metals Mining Inc.

The strategic picture at Nord has shifted following a recent land consolidation. Basa noted that "with Nord now holding title to all the area mining leases following the recent acquisition, we can test structures that could not be drilled under fragmented ownership." That consolidated tenure opens access to vein corridors previously inaccessible by boundary constraints — a meaningful operational change in a district where the best silver often occurs along strike from known intercepts. Every metre, Basa added, "feeds directly into our planned resource update and, in turn, a future production plan."

Silver at $74.18/oz heading into Wednesday's session keeps the economics of high-grade narrow-vein silver attractive. In the Cobalt-Gowganda district, where historic mines operated on veins measured in centimetres, the combination of a multi-metre mineralized envelope with critical mineral by-products — cobalt in particular — adds a second revenue stream that was largely ignored in earlier production eras. Nord's Castle East program is advancing at a moment when that co-product story carries increasing weight with both resource economists and policy-focused investors tracking North American critical mineral supply.
