Hana Mining Ltd. has announced the most recent assay results received from Zone 5 infill drilling activity at the Ghanzi sediment hosted Copper-Silver Project in Botswana.
The results at Zone 5 continue to contribute high-grade copper mineralisation to support the known inferred mineral resource into the indicated classification. The emerging geological interpretation of Zone 5’s mineralisation is presenting a high-quality copper and silver deposit that shows potential of becoming an important source of long term feed for a regional processing complex.
While Zone 5 connects to Discovery Metals’ NE Mango prospect at depth (see Hana press release November 1, 2012), it is also near to Ghanzi’s Banana Zone and part of the Preliminary Economic Assessment (“PEA”) supported mine plan released May 2012.
In June 2012, Hana published an NI 43-101 compliant Technical Report which described Zone 5 with an inferred category mineral resource estimate of 520 Mlbs copper grading 1.47% and 6.8 Moz of silver grading 13.2 g/t at a 0.40% Cu cutoff, from 71 core and RC holes for 7,786 metres.
The resource numbers showed promise, and the drilling program through 2012 has focused on proving the potential through infill drilling as well as exploring open extensions to the depths of 650 metres below surface. Hana has now drilled 179 holes for 32,420 metres at Zone 5.
Hana Mining President and CEO, Marek Kreczmer comments says: “These and the previously announced deep drill results suggest that Zone 5 could become a standalone mining operation.”
The drilling program and results are reviewed and approved by Marek Kreczmer, Chief Executive Officer for Hana. He is the qualified person as defined in NI 43-101 and has reviewed the technical information in this press release.
Drill core is logged and photographed. Mineralized intervals are split in half by sawing and sampled at site. The remainder of the core is kept as a permanent record. Samples are placed into labeled bags, closed and packed into sealed bags that are shipped to Scientific Services Laboratory in Cape Town, South Africa.
Hana has implemented an industry-standard QA/QC program that includes the blind insertion of certified standards, duplicates and blanks into the sample stream.
