Altamin (ASX: AZI) has received promising third tranche of assay results from the 2024 channel sampling program at the Gorno Project in Italy.
The channelling focused on capturing areas of mineralisation identified during structural and geological mapping programmes in newly accessible underground workings outside of the existing MRE footprint.
The programme has continued to prove successful by returning high-grade intercepts that extend the mineralisation into areas outside of the current MRE.
The channel sampling work programme at Gorno was designed to encompass new exploration areas outside of the current Ore Block Model (OBM), aimed to extend the mineral inventory footprint of the MRE.
This third batch of assays has been received for 128 rock samples (47 channels), systematically covering three main target areas situated on the Piazzole mine level 990m:
1. Piazzole East: a series of access and development drives,
Sampling in Piazzole East returned multiple high-grade assays along the development, indicating that mineralisation extends underneath the current OBM, both down-dip and laterally.
Assays results from Pian Bracca North have confirmed the presence of well-mineralised horizons that extend to the northeast of the current OBM.
This mineralised trend is limited by the extent of development of Piazzole but continues further in the above mine level, Parina 1040L and associated sublevels.
The sampled areas were previously inaccessible and have undergone rehabilitation to allow the geology team to safely enter, capture the development using LiDAR and conduct sampling. Detailed geological and ore mapping has identified that these areas, despite undergoing historic partial extraction, contain Zn-Pb- Ag mineralisation that is not currently captured in the MRE.
Out of the 47 channels sampled, 27 returned significant intersections.
Consistent with the rest of the channel programme, all accessible drives in the area have been sampled in their entirety and have maintained regular spacing of <40m while representatively sampling both mineralised and non-mineralised wall rock.
