Touquoy mine reboot: stockpile plan and in‑pit tailings explained for engineers
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Touquoy gold mine in Nova Scotia will restart processing about three million tonnes of stockpiled ore containing roughly 38,000 oz of gold, a 14‑month campaign expected to generate C$150 million in economic activity and nearly 200 jobs, with first shipments to the Royal Canadian Mint targeted for early 2027. Atlantic Mining Nova Scotia has already awarded over C$56 million in local contracts, including C$48 million to Alva Construction for material movement and waste rock and C$8 million to MacGregors Industrial Group to refurbish the mill. Tailings will be deposited underwater in the exhausted Touquoy pit under a C$79.9‑million reclamation bond, a first for Nova Scotia but consistent with global in‑pit deposition practice and a potential precursor to St Barbara’s proposed 11‑year 15‑Mile Processing Hub.
Technical Brief
- Tailings will be deposited subaqueously in the exhausted Touquoy pit, using in‑pit deposition to limit oxygen exposure.
Our Take
Within our 1,215-item mining database, Nova Scotia appears far less frequently than western Canadian provinces, so the Touquoy mine and 15-Mile Processing Hub together mark one of the more substantial gold project clusters on Canada’s Atlantic coast.
The projected C$5 billion in economic spinoffs over an 11‑year life for the 15‑Mile Processing Hub signals a scale more typical of mid‑tier gold districts in Ontario or Quebec, suggesting this hub could anchor further satellite deposits in Guysborough County if permitting holds.
