Hana Mining Ltd. ("Hana" or the "Company") (TSX VENTURE:HMG)(FRANKFURT:4LH) is
pleased to announce its most recent drilling results from the completion of six
infill and down-dip extensional diamond-drill holes at the Banana Zone at its
Ghanzi sediment hosted Copper-Silver Project in Botswana.
Infill and extensional drilling was carried out on Northeast Fold area ("NEF")
(between sections 70200 to 70700; Figures 1 and 2) to convert a substantial
amount of the NI 43- 101 compliant resources within this area into the Indicated
category from the Inferred category.
These results are from new holes and are in addition to those used in the most
recent NI 43-101 compliant Indicated and Inferred mineral resource calculation
(see Table 1 at the end of this press release for the results from all six drill
holes). The mineralization remains open at depth and along strike.
Highlights of recent drilling results:
The latest results demonstrate that the Banana Zone (NEF) contains areas which
host high-grade copper-silver mineralization.
-- Core length intercepts of:
-- 3.63% CuEq(1) (3.12% Cu and 35.0 g/t Ag) over 5.8 metres within
a wider mineralized interval of 1.81% CuEq(1) (1.58% Cu and 16.0
g/t Ag) over 14.3. metres in hole HA-526-D,
-- 1.50% CuEq(1) (1.31% Cu and 13.0 g/t Ag) over 15.2 metres within
a wider mineralized interval of 1.10% CuEq(1) (0.97% Cu and 9.0
g/t Ag) over 24.2 metres in hole HA-529-D,
-- 3.21% CuEq(1) (2.44% Cu and 53.0 g/t Ag) over 5.4 metres within
a wider mineralized interval of 1.77% CuEq(1) (1.39% Cu and 26.0
g/t Ag) over 11.6 metres in hole HA-527-D.
(1) Copper equivalent calculated using US$3.00/lb Cu, US$30/oz Ag and is not
adjusted for metallurgical recoveries. The formula used is as follows: CuEq =
Cu% + (Ag g/t x 0.01458).
Discussion of Results:
The NEF area consists of a plunging anticline where up to four intervals of
high-grade copper mineralization within a broader low grade mineralized envelope
were encountered within the hanging siltstones and mudstones and footwall
sandstones (Figure 3). The latest drilling results from the NEF infill drilling
program continue to add significant high-grade copper over thick intervals
within the NEF area and cover additional extensions along the fold plunge axis.
This zone is still open along strike and at depth.
The latest drilling results (holes HA-526-D, HA-527-D, and HA-528-D) confirm and
extend mineralization along the northwest limb at the NEF where copper and
silver grades increase with depth. In this particular area of the Northeast
fold, mineralization is hosted within two high-grade zones hosted within a lower
grade envelope. Drilling is continuing at NEF.
Hana Mining's CEO and Chairman, Marek Kreczmer, commented as follows:
"The latest drilling results from NEF compare favorably to previous drilling
results in this area and to the grades in our latest resource estimate which was
released on May 14, 2012. We now have drills at the Banana Zone (NEF), Zone 5
and Zone 6 which I expect will continue to add more high-grade material to our
resource base."

Qualified Person and Quality Assurance/Quality Control
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 labelled 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.
About Hana Mining's Ghanzi Copper-Silver Project in Botswana:
The Ghanzi Project is located in the center of the Kalahari Copper Belt in
northwestern Botswana. The Ghanzi property covers 2,149 square kilometres, and
contains sediment-hosted copper-silver deposits with a demonstrated cumulative
tested strike length of 70 kilometres. This favorable geology extends over an
estimated strike length of 600 kilometres.
On May 14, 2012 Hana Mining released results of its most recent NI 43-101
compliant Preliminary Economic Assessment ("PEA") for the Ghanzi Project. The
PEA details a 10,000 tonne per day open-pit mining and milling operation at the
Banana Zone and Zone 5 at an initial capital expenditure of US$285.5 million.
This operation is expected to produce approximately 66.4 million pounds of
copper and 878,000 ounces of silver annually over a minimum 13-year mine life.
The project will benefit from proposed rail and power infrastructure expansions,
along with proximity to local population centers and workforce. A feasibility
study was carried out (funded by the World Bank and the governments of Botswana
and Namibia) to support completion of a rail line link that would connect
Botswana with the Namibian port of Walvis Bay, on the Atlantic coast. The
closest existing railhead to port is at Gobabis, in Namibia, approximately 550
km from our property. Construction is well advanced on the 600MW expansion of
the government-owned Moropule Power Plant, having secured US$825 million project
funding in May 2009. The Ghanzi Copper-Silver Project is currently accessed by
the paved Trans-Kalahari highway, which passes within 40 km of the property.
The Ghanzi property is one of Africa's premier future copper-silver resources.
