30 Second Briefing
Meridian Mining has raised £25 million in its London Stock Exchange debut, issuing 2.7 million shares at 92p and closing at 94.70p, giving a market capitalisation of about C$802 million (£434 million) across its listings. The funds will advance the Cabacal gold-copper project in Mato Grosso, an advanced-stage VMS deposit with pre-feasibility work outlining a 10-year mine life, 141,000 gold-equivalent ounces per year and a post-tax IRR of about 61%. Management is targeting FTSE All-Share inclusion at the next rebalance and FTSE 250 entry within 12 months.
Technical Brief
- Equity raise combined a £25 million institutional placing with a £2.5 million retail offer.
- 2.7 million new shares were issued at 92p, trading up to 94.70p on debut.
- Dual-listed structure now spans Toronto (TSX), London Main Market and OTC/Frankfurt venues.
- London listing sits in the Equity Shares (Commercial Companies) category, relevant for index eligibility.
- Cabacal is described as an advanced-stage volcanogenic massive sulphide system in Mato Grosso, Brazil.
- Project is positioned as the cornerstone of a scalable gold–copper platform in Brazil for Meridian.
Our Take
Meridian Mining is one of only a few copper–gold developers in our recent coverage targeting a FTSE 250 slot within 12 months, signalling an ambition to tap deeper UK institutional capital than typical TSX-only peers such as American Eagle Gold in the March 2026 financing piece.
The implied C$802 million market capitalisation for Cabacal places Meridian at the upper end of single-asset South American copper–gold developers in our database, which may raise expectations for rapid de-risking of mine-life and IRR assumptions in Mato Grosso.
With Ausenco named alongside Cabacal and a 10-year mine life outlined, the project is following a similar engineering-led de-risking path to other copper projects in our mining corpus, where early engagement of tier-one designers has often been a prerequisite for offtake-linked funding or index inclusion ambitions.
