Canadian exploration company Hana Mining has encountered high-grade copper-silver mineralisation at its Ghanzi sediment in Botswana.

The Ghanzi property covers 2,149km² and it includes sediment-hosted copper-silver deposits with a demonstrated cumulative tested strike length of 70km.

Twelve infill diamond drill holes in the Banana Zone were completed along strike at the South Limb.

Infill and down dip drilling was carried to convert a substantial amount of the NI 43-101 compliant resources within this area into the indicated category from the inferred category and extend current indicated resources down dip.

Hana Mining’s CEO and chairman Marek Kreczmer said the recent infill drilling results demonstrate that high-grade copper-silver mineralization is consistent along strike and dip at the South Limb Definition area.

"We are finding that copper-silver mineralization in this area is steeply dipping and parallel to the stratigraphy," said Kreczmer.

"Complex structures, such as local folding and micro-faulting have shown some thickening of the mineralization much like that seen in the Northeast Fold area."

The drilling programme and results have been reviewed and approved by Kreczmer.
