VANCOUVER, British Columbia, Nov. 19, 2025 (GLOBE NEWSWIRE) -- Canterra Minerals Corporation (TSXV:CTM) (OTCQB: CTMCF) (FSE:DXZB) (“Canterra” or the “Company”) is pleased to announce step-out drilling results, including 7.73% Copper Equivalent (“CuEq”) over 4.45 metres, its 100%-owned Buchans Project in the Central Newfoundland Mining District. The Buchans Project is located at the site of the world-renowned past-producing Buchans Mine, approximately 50 kilometres north of Equinox Gold’s Valentine Gold Mine and 34 km northwest of Teck’s past producing Duck Pond Mine. In May 2025, Canterra intersected 5.97% CuEq 1,2 over 5.35 metres in hole H-25-3539 (news release dated May 20, 2025 ).

This latest drilling was completed in 3 holes at approximately 50 m step-outs, which have successfully extended the Two Level Zone located outside the Lundberg resource. These results indicate high-grade mineralization remains open down plunge to the north. Drilling Highlights: 7.73% CuEq over 4.45 metres (1.11% Cu, 11.38% Zn, 7.02% Pb, 125.5 g/t Ag & 1.24 g/t Au) 1.85% CuEq over 26.0 metres (0.84% Cu, 2.13% Zn, 1.30% Pb, 8.2 g/t Ag & 0.08 g/t Au), extending the Lundberg stockwork zone 80 m beyond the current Lundberg Resource.

At depth, the hole returned mineralization of 1.72% CuEq over 6 m (0.28% Cu, 3.36% Zn, 1.55% Pb, 8.6 g/t Ag & 0.12 g/t Au) Two Level Zone mineralized footprint has now expanded to approximately 200 m x 50 m “These drilling results confirm that Buchans has the potential to host a much larger and higher-grade system than previously defined,” stated Chris Pennimpede, President and CEO of Canterra. “Intersecting high-grade copper mineralization with gold mineralization in step-out drilling well outside the existing resource, demonstrates both the strength and continuity of mineralization. With the Two Level Zone expanding and the Lundberg stockwork zone extending, we are seeing clear evidence that Buchans remains one of Canada’s most prospective VMS districts.
