The exploration permit, Contrato MN/PP/009/08, is held by a joint venture between Redcorp Empreendimentos Mineiros, LDA. (Redcorp) and Empresa de Desenvolvimento Mineiro S.A. (EDM) a Portuguese Government owned company for the mining sector. Redcorp holds an 85% interest and EDM holds a 15% interest.
Redcorp is a 75% subsidiary of TH Crestgate GmbH (TH Crestgate), a Swiss investment company and a 25% subsidiary of Ascendant, a Canadian company listed on the Toronto Stock Exchange.
May 25, 2022 - Ascendant Resources has completed more than US$9.0M of project related expenditures on the Lagoa Salgada Project and paid TH Crestgate, a wholly owned subsidiary of M&FI. This thereby fulfills the first phase of the earn-in conditions to increase its effective ownership interest from 25% to 50% in the Lagoa Salgada VMS project. Ascendant expects to fully satisfy the conditions of the Earn-In agreement and to increase its stake in the Project to 80% by December 22, 2022.

Deposit Type

  • VMS
  • Breccia pipe / Stockwork
  • Sedimentary - Volcanogenic


Summary:

The LS deposit is a polymetallic, VMS deposit. VMS ore deposits are a type of metal sulphide deposits which are associated with and created by volcanic-associated hydrothermal events in submarine environments. They occur within environments dominated by volcanic or volcanic derived volcano sedimentary rocks, and the deposits are coeval and coincident with the formation of the volcanic rocks. VMS deposits form on the seafloor around undersea volcanoes along many mid ocean ridges, and within back-arc basins and forearc rifts.

VMS deposits are characterized by clusters of lenses occurring within a distinct stratigraphic layer. The extensive alteration zone on the property suggests that hydrothermal activity was prolonged and that additional lenses associated with separate alteration zones may exist.

The entire Property (exploration permit) is covered by a paleo-fluvial fan that ranges in thickness up to 200 metres (m) within the Tertiary Sado Basin and averages 135 m over the deposit area. The Tertiary sedimentary rocks unconformably overlie rocks of the Volcano-Sedimentary Complex of the IPB. This sequence of rocks ranges in age from Upper Famenian to Middle Visean and is represented on the property by a northwestsoutheast lineament which is approximately 8 km long and over 1 km wide.

The LS Project currently comprises two known deposits, the Venda Nova North and South Deposits. The deposits are folded, faulted, and interpreted to occur mostly o ........


Mining Methods

  • Cut & Fill
  • Sub-level stoping
  • Transverse stoping
  • Paste backfill


Summary:

The Lagoa Salgada Project is planned to be mined using underground mining methods. The option of open-pit mining was discarded due to the characteristics and depth of the orebody.

The proposed underground mine design supports the extraction of 2.0 million tonnes of ore per year (“Mtpa”) through a combination of transverse sublevel stoping and cut&fill. Paste backfill is used in both mining methods to maximise ore recovery and productivity. A main decline, starting from the surface portal located close to the processing plant, will be used to access the mine. This main decline then splits into two ramps, one for each mine zone (i.e., “North and South”). A fleet of LHDs (load-haul dumps) and trucks will be used for the loading and hauling of material from production areas to the orepass system. From the orepass collecting points, trucks will haul the ore to the surface. Waste is also transported to the surface by trucks.

A pre-production development programme will be required to provide access to the initial stoping levels in the North Zone during the first two years. Production will start in the second year, reaching the nominal plant feed in the fourth year.

The mine portal will be situated close to the processing plant. The main ramp bifurcates into two independent declines, one for each mine area. In each zone, the internal decline connects all working levels.

The ramps were designed with a 25m turning radius and a maximum gradie ........
