SnapshotGorno is largely a “brown-fields” project due to the extensive historical mining activities, which ceased in the 1980s. The area benefits from well-developed existing infrastructure, including roads, grid power, water, sanitation and several nearby towns with plentiful available accommodation and facilities.

At the Gorno Project activities continued towards completing the Phase 1 Definitive Feasibility Study, which is intended to provide technical inputs necessary to specify the project’s environmental impacts and therefore support the proposed mining licence application.

Summary:

The Gorno mineral district is an Alpine Type lead-zinc deposit similar to Mississippi Valley Type (MVT) lead-zinc deposits. The mineralisation is broadly stratabound with some breccia bodies and veining also observed. Higher grade and thicker mineralisation are often associated with late-stage brittle faulting which is generally orientated north-south or east-west. The mineralogy is simple consisting of low iron sphalerite, argentiferous galena and minor pyrite. Mineralisation is hosted by the Metallifero Formation which consists predominantly of limestones with interbedded shales in the higher parts of the sequence. The Gorno deposit lies in the “Lombard Basin” of the Italian Southern Alps where during the Permian- Triassic periods a thick sedimentary pile was formed as a result of strong subsidence.
