Canterra Minerals Expands Newfoundland Exploration Portfolio with Strategic Staking

of Seal Pond Massive Sulfide Prospect

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 kilomet res (“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 o r 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 t he Seal Pond prospect has significant

potential and look forward to applying modern exploration techniques to unlock new discove ries 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:

From To Cu (%) Pb (%) Zn (%) Au (ppb)

51.55 51.75 0.54 0.04 2.84 80

100.3 100.5 1.22 - 0.08 70

*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 Inst itute 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 host s

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.
