Vancouver, B.C. (March 18, 2025) – Canterra Minerals Corporation (TSXV:CTM) (OTCQB:CTMCF) (FSE:DXZB) (“Canterra” or the “Company”) is pleased to announce the strategic staking of 19 mineral claims (5km2) covering the Seal Pond Volcanogenic Massive Sulfide (VMS) prospect in central Newfoundland. The newly acquired claims are located 20 kilometres (“km”) east of the Company’s Buchans project, a world renowned, historic, high-grade volcanogenic massive sulphide (“VMS”) critical metal mining camp.

Highlights:

• Seal Pond prospect is hosted by volcanic rocks of the Mary March Group that correlate with productive rocks of the Buchans Group and host several high-grade VMS occurrences with similarities to the Buchans orebodies.
• Adds more of the prospective rocks to our broader regional exploration approach to make a new discovery in this prolific massive sulphide camp
• further expands Canterra's Newfoundland critical minerals project portfolio within the Central Newfoundland Mining District where Canterra’s current land position is the largest in the district and is host to 7 known undeveloped deposits with current and or historic mineral resource estimates prepared in compliance with National Instrument 43-101 at the time of their estimation (see Canterra Website for details ).
• Drill highlights include intervals grading 2.84% Zn and 1.22% Cu, within the favourable Buchans Group rocks and associated alteration and mineralization signatures.  Drilling has not taken place on the Seal Pond property since 2006 and has been limited in scope.

“Canterra's acquisition of these claims underscores its commitment to expanding its exploration footprint in proven mining jurisdictions. "This staking represents further consolidation the Buchans group rocks to secure the regional potential in this belt to make a new high-grade critical minerals discovery," said Chris Pennimpede, President & CEO of Canterra Minerals. "We believe the Seal Pond prospect has significant potential and look forward to applying modern exploration techniques to unlock new discoveries in this well-endowed district."

Strategic Significance

Historical exploration has identified favorable lithologies and alteration signatures indicative of VMS mineralization. Historic drill results from this prospect include:

*Assays are historical in nature having been collected by previous operators other than Canterra.

Next Steps

Canterra has initiated a comprehensive review of historical exploration data and will consider follow-up field programs once this review is complete. The objective of this review and subsequent field work will be to identify drill targets and ultimately advance the Seal Pond prospect toward discovery of significant new deposits.

About Canterra Minerals
Canterra is a diversified minerals exploration company focused on critical minerals and gold in central Newfoundland. The Company’s projects include six mineral deposits located in close proximity to the world-renowned, past producing Buchans mine and Teck Resources’ Duck Pond mine that collectively produced copper, zinc, lead, silver and gold. Several of Canterra’s deposits support current and historical Mineral Resource Estimates prepared in accordance with National Instrument 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards for Mineral Resources and Mineral Reserves current at their respective effective dates. Canterra’s gold projects are located on-trend of Calibre Mining’s Valentine mine currently under construction and cover a ~60 km extension of the same structural corridor that hosts mineralization within Calibre’s mine project. Past drilling by Canterra and others within the Company’s gold projects intersected multiple occurrences of orogenic style gold mineralization within a large land position that remains underexplored.
