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 14
infill diamond drill holes in the Banana Zone at its Ghanzi sediment hosted
Copper-Silver Project in Botswana.
Infill drilling was carried out on the Northeast Fold area (between sections
69125 to 70425 at the Northeast Fold; 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 14 drill
holes). The mineralization remains open at depth.

Highlights of recent drilling results:
-- The latest results continue to confirm the continuity of copper-silver
mineralization at the Northeast Fold area of the Banana Zone.
-- Core lengths intercepts of
-- 2.17% CuEq(1), (1.82% Cu and 24.0 g/t Ag) over 8.0 metres within a
wider mineralized interval of 0.96% CuEq (0.79% Cu and 12.0 g/t Ag)
over 24.7 metres in hole HA-434-D,
-- 2.59% CuEq(1), (1.98% Cu and 42.0 g/t Ag) over 4.5 metres within a
wider mineralized interval of 1.34% CuEq (1.05% Cu and 20.0 g/t Ag)
over 10.0 metres in hole HA-407-D,
-- 1.21% CuEq(1), (1.17% Cu and 3.0 g/t Ag) over 1.5 metres within a
wider mineralized interval of 0.22% CuEq (0.19% Cu and 2.0 g/t Ag)
over 15.7 metres in hole HA-441-D,
-- 0.94% CuEq(1), (0.85% Cu and 6.0 g/t Ag) over 7.9 metres within a
wider mineralized interval of 0.52% CuEq (0.45% Cu and 5.0 g/t Ag)
over 27.7 metres in hole HA-439-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:
These are the first set of results from the 2011 infill drilling program for the
Northeast Fold area which is located at the most northeast part of the Banana
Zone. This area consists of a plunging anticline where thick intervals of copper
mineralization were encountered. Like many parts of the North Limb North area,
high-grade copper silver mineralization at the Northeast Fold bifurcates and is
contained within a broader low grade mineralized envelope. Mineralization at the
Northeast Fold is open along plunge and along dip of this anticlinal structure.
Further infill drilling results from the Northeast Fold are expected soon.
Development Update
The following engineering and consultation activities are ongoing:
-- Work on the revised resource estimate for the Banana Zone is continuing
as expected and the Company expects to release the results of this
resource estimate in the second quarter of 2012.
-- Work continues on the Preliminary Economic Assessment ("PEA") which is
also expected to be completed in the second quarter of 2012.
Hana Mining's CEO and Chairman, Marek Kreczmer, commented as follows:
"The Northeast Fold is another key area where we are investigating the potential
of open pit and underground mining operations. Not only is mineralization open
along dip along the limbs of the folds in this area, but also along plunge of
the top of the fold. This area is also attractive given that relatively
high-grade mineralization is found over thick intersections."
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 ALS Chemex Laboratory in Johannesburg, South Africa or
Scientific Services Laboratories 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. Hana Mining released results of its
most recent NI 43-101 compliant resource estimate for the Ghanzi Project on
December 20, 2010, announcing an Indicated mineral resource of 585 million
pounds of copper and 12 million ounces of silver from 19.7 million tonnes at a
grade of 1.35% copper and 19.7 g/t silver. All of the Indicated resources are
from the Banana Zone. There are also Inferred resources of 2.4 billion pounds of
copper and 40.6 million ounces of silver from 91.2 million tonnes. This Inferred
mineral resource estimate consists of 69.9 million tonnes grading 1.10% Cu and
14.98 g/t Ag in the Banana Zone, 13.4 million tonnes grading 1.66% Cu and 12.11
g/t Ag in Zone 5, 6.3 million tonnes grading 1.5% Cu and 6.7 g/t Ag in Zone 6,
and 1.6 million tonnes grading 0.85% Cu and 6.4 g/t Ag in the Chalcocite Zone;
all at a cut-off grade of 0.75% Cu.
The Banana Zone exhibits certain areas of higher grade Cu and Ag mineralization,
particularly between sections 49700 to 52000 on the North limb and sections
63000 to 71000 on both the North and South limbs, which represent an opportunity
to locate starter pits and mine initial tonnages at higher than average grades.
These higher grade pockets tend to be well within open pit depth parameters and
represent opportunities to improve early cash flow and overall returns in
development.
The project will benefit from proposed rail and power infrastructure expansions,
along with proximity to local population centers and workforce. A feasibility
study is currently underway (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 has begun 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 15 km of the property.
The Ghanzi property is one of Africa's premier future copper-silver resources.
