Owners

CompanyInterestOwnership
Altamin Ltd. 100 % Indirect
The Gorno Project has been transferred to Vedra Metals SRL (Vedra), a special purpose jointventure company owned by Altamin (via its wholly owned subsidiary, Energia Minerals (Italia) SRL (EMI)) and Appian Italy B.V (Appian), following completion under the binding subscription and joint venture agreement.

Appian has paid ~A$3.8 million1 (US$2.6 million) to earn an initial interest of approximately 9.96% in Vedra, with all conditions precedent to the remaining first tranche funding having been satisfied or waived.

Vedra to draw a further ~A$10.9 million1 (US$7.4 million) of first tranche funding under the Joint Venture Agreement, following which Appian’s interest in Vedra will increase up to approximately 29.9%

It is intended that this funding is applied to a ~19,000m drilling campaign, completion of a Definitive Feasibility Study (DFS) and completion of Gorno permitting.

Deposit Type

  • Mississippi Valley Type
  • Stratabound
  • Breccia pipe / Stockwork


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.


Mining Methods

  • Drift & Fill
  • Transverse stoping
  • Longitudinal retreat
  • Paste backfill


Summary:

The Gorno mine already has established underground access from surface at multiple vertical levels via short adits into the hillside, which minimises up-front development and therefore development risk. Itis proposed that the mechanised mining methods employed will vary according to the attitude, geometry and thickness of the mineralisation, to maximise the extraction recovery whilst minimising dilution and waste development. Mining methods will be "Drift and Fill" and "Long Hole Retreat and Fill (Transverse)" in part of the deposit characterised by shallow dipping mineralisation; and "Longitudinal Long Hole Retreat and Fill" in steeper dipping areas. Cementitious paste fill is proposed to be used to stabilise stope voids.

Access from surface to underground is currently available from historical development on multiple levels, hence, the primary access to the orebody is via the existing Ca Pasi adit (to be enlarged to 4.7m x 4.7m from 3.5mW x 3.5mH). However, the new processing plant is to be constructed at an existing modern industrial site named the Zorzone Industrial Area (ZIA) which lies ~1km to the south and at the same elevation as the midpoint of the Zorzone mineralisation (890m RL). Therefore, a new conveyor ramp (ZIA Ramp, 5.5mW x 3.5mH) is required to efficiently connect the existing underground mine to the new processing plant at the ZIA process plant site. The ZIA ramp will have an almost flat inclination and will be developed from either end (both fro ........
