FLSmidth flowsheet for Vizsla Silver’s Panuco: design and capex notes for engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Vizsla Silver has awarded FLSmidth an equipment supply and engineering contract for the full process plant flowsheet at its wholly owned Panuco silver-gold project in Sinaloa, Mexico, covering all major unit operations defined in the planned 2025 feasibility study. The scope spans comminution, classification, flotation and dewatering circuits, with FLSmidth responsible for detailed process design and specification of key machines such as mills, cyclones, flotation cells and filters. Engineering work starts immediately, giving Panuco a vendor-anchored flowsheet ahead of final plant sizing and capex decisions.
Technical Brief
- FLSmidth’s scope is an equipment supply agreement, not just a front-end engineering mandate.
- Integrated supply-and-engineering package should reduce interface risk between comminution, flotation and dewatering vendors.
- Early OEM involvement typically shortens detailed design and procurement lead times for mills and flotation cells.
Our Take
Our database shows Panuco already underpinned a 2%–3.5% uncapped NSR royalty in the Elemental Royalty–Vizsla Royalties deal, so FLSmidth’s flowsheet work will directly influence the long‑term cash flow profile that royalty investors are banking on.
The recent FIFOMI working‑capital facility for Vizsla Silver’s Panuco project suggests Mexican state-backed lenders see enough technical and permitting momentum in Sinaloa to support near‑term advancement, which a defined process flowsheet will help to de‑risk further.
