CRITICAL MINERALS ASSET

Lemarchant

A high-grade zinc-copper deposit in central Newfoundland, in the same volcanic belt as the former Duck Pond mine. Canterra holds a drilled-out polymetallic deposit that remains open along strike and at depth, with multiple untested targets nearby.

THE OPPORTUNITY

The Case for Lemarchant

Already defined deposit

Lemarchant has been drilled with more than 165 holes totaling over 50,000 metres. The deposit is defined to about 210 metres depth, hosts a historical 2018 resource estimate, and remains open along strike and at depth.

Five metals in one system

The deposit carries zinc, copper, lead, silver and gold together. Canterra's first drill hole into the deposit in 2024 returned 28 metres grading 5.42% zinc, 0.48% copper, 1.33% lead, 67.9 g/t silver and 1.19 g/t gold.

Proven mining district

Lemarchant sits in the Tally Pond volcanic belt, the same belt that hosted Teck's Duck Pond copper-zinc mine about 20 km to the northeast. Duck Pond operated until 2015 and was connected to the Newfoundland Hydro grid.

GEOLOGY & MINERALIZATION

High-grade district

Lemarchant lies within the Tally Pond volcanic belt, a roughly 50 km long corridor of ancient volcanic rocks that hosts several zinc-copper deposits, including the former Duck Pond mine.

Exceptional grades

Historic drilling returned intervals such as 20.55 metres at 12.8% zinc, 1.2% copper and 69.1 g/t silver, and 4.7 metres at 27.5% zinc and 181 g/t silver. Silver and gold add value throughout the deposit.

Two styles of mineralization

Layers of massive sulphide, up to 30 metres thick, occur in two zones: a Main Zone from about 120 to 210 metres depth and a deeper Northwest Zone. Below these layers, a copper-rich network of sulphide veins points to the system's feeder zone.

Modern Exploration

Canterra ran ground geophysical surveys in 2022 and 2023 that measure how rocks conduct electricity, a proven way to detect buried sulphides. The work identified multiple high-priority drill targets around the deposit.

RESOURCE / MINERALIZATION INVENTORY

HISTORICAL ESTIMATE

2018 historical estimate at a 4.0% zinc-equivalent cut-off. Historical estimate — not a current mineral resource or mineral reserve. A qualified person has not done sufficient work to classify this estimate as current, and Canterra is not treating it as current. It is separate from, and not included in, the 2026 Lundberg resource.

LEMARCHANT EXPANSION

Current Program & Drilling

The October 6, 2026 update reports drilling underway at Lemarchant as part of a 6,000 m district exploration program. Results are pending and expected through the remainder of 2026 and into 2027; gravity survey results are expected in Q4 2026. Work is intended to test extensions and new targets. Timing and outcomes remain uncertain. The cards below summarize the earlier 2024 drilling results.

Confirming the deposit

Hole LM-24-164 cut 28 metres of polymetallic mineralization grading 5.42% zinc, 0.48% copper, 1.33% lead, 67.9 g/t silver and 1.19 g/t gold, including 9.5 metres at 10.59% zinc. The result supports future resource modeling.

A new copper zone

Hole LM-24-165 intersected copper-rich sulphide veining west of the deposit, including 0.87 metres at 4.25% copper. Canterra compares this style of mineralization to the nearby Duck Pond deposit.

Untested targets

Targets remain around the deposit, including a possible fault-offset extension of the Main Zone, a northern extension of the Northwest Zone, a deep target about 600 metres south, and shallow zinc soil anomalies that have never been drilled.
