- The Mineral Resource estimate (MRE) for Gorno has been updated as a result of the successful exploration initiatives undertaken post-July 2021 in several underexplored areas of the Gorno mine. The update reported above a cut-off grade of 1% zinc is:
- The modelling methodology is unchanged from the July 2021 MRE. Whilst the global tonnage and grade remains the same the Indicated resource category now accounts for 72.6% of the total resource, an increase of 18% and the oxide component of the mineralisation has reduced by 27%.
- Gorno’s mineralisation remains open in all directions outside of the MRE with numerous step-out targets ready to be drill tested from current underground development.
Alta Zinc Limited (Alta or the Company) (ASX: AZI) is pleased to announce an update to the Mineral Resource estimate (MRE) (Figure 1) for its Gorno zinc-lead-silver deposit in the northern Italian Province of Bergamo. Geraint Harris, MD of Alta Zinc commented: “I am delighted that the ongoing work and assessment by our geology team has resulted in an updated MRE with 18% more tonnes now in the Indicated category and 27% fewer tonnes in the oxide component of the mineralisation. This knowledge increase in very specific areas of the Mineral Resource is a direct result of our ability to get underground and directly map the rocks, allied with leveraging the extensive historical exploration records we have at Gorno. Future technical studies will now utilise this updated Mineral Resource base to produce a further de-risked mining plan.”
The deposit is approximately a 3-hour drive from the main Port of Genoa, and a 1-hour drive from Bergamo International Airport (Figure 2).
The MRE update was completed by CSA Global Pty Ltd (CSA Global) in Perth, Australia.
