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 10
infill diamond drill holes in the Banana Zone at its Ghanzi sediment hosted
Copper-Silver Project in Botswana.
Infill and down dip drilling was carried out on the South Limb area (between
sections 63075 to 63850 at South Limb Definition Area; 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 and to extend
current Indicated resources down dip.
These results are from new holes and are in addition to those used in the most
recent NI 43-101 compliant Inferred mineral resource calculation (see Table 1 at
the end of this press release for the results from all 10 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 South Limb Definition area of the
Banana Zone.
-- Core lengths intercepts of
-- 3.69% CuEq(1)(2.96% Cu and 50.0 g/t Ag) over 2.5 metres within a
wider mineralized interval of 0.74% CuEq(1)(0.60% Cu and 10.0
g/t Ag) over 16.6 metres in hole HA-422b-D,
-- 3.21 CuEq(1)(2.64% Cu and 39.0 g/t Ag) over 2.4 metres within a
wider mineralized interval of 1.58% CuEq(1)(1.32% Cu and 18.0
g/t Ag) over 5.1 metres in hole HA- 387b-D,
-- 2.75% CuEq(1)(2.26% Cu and 34.0 g/t Ag) over 3.7 metres within a
wider mineralized interval of 2.07% CuEq(1)(1.72% Cu and 24.0
g/t Ag) over 5.2 metres in hole HA-414b-D,
-- 2.61% CuEq(1)(2.10% Cu and 35.0 g/t Ag) over 4.3 metres within a
wider mineralized interval of 1.84% CuEq(1)(1.48% Cu and 25.0
g/t Ag) over 6.2 metres in hole HA-394-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).
The Company also announces that it has granted Incentive Stock Options (the
"Options") to purchase up to an aggregate 2,700,000 common shares of the Company
to directors, officers and employees of the Company. The Options are exercisable
at $2.13 per share and expire on February 27, 2017. All securities issued upon
exercise of the Options are subject to a hold period expiring four (4) months
after the date of grant. The subject Options will vest quarterly over 24 months,
in 8 equal tranches, with the first tranche vesting May 27, 2011. The Options
are subject to the terms and conditions of the Company's Stock Option Plan.
Discussion of Results:
The infill drilling program at the South Limb continues to confirm that
copper-silver mineralization is relatively high-grade and continuous along
strike at the South Limb (Figure 3). This drilling will allow for the conversion
of more mineral resources from the Inferred category into the Indicated
category.

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 infill results are continuing to confirm our original interpretation along
the South Limb. Copper-silver mineralization in this area is steeply dipping and
parallel to the stratigraphy. 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."
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 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. 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 762 million
pounds of copper and 16 million ounces of silver from 37.4 million tonnes at a
grade of 0.93% copper and 13.4 g/t silver. All of the Indicated resources are
from the Banana Zone. There are also Inferred resources of 5.6 billion pounds of
copper and 85.4 million ounces of silver from 423.9 million tonnes. This
Inferred mineral resource estimate consists of 225.4 million tonnes grading
0.64% Cu and 8.1 g/t Ag in the Banana Zone, 20.7 million tonnes grading 1.23% Cu
and 8.7 g/t Ag in Zone 5, 16.7 million tonnes grading 0.86% Cu and 4.0 g/t Ag in
Zone 6, and 161.1 million tonnes grading 0.45% Cu and 3.6 g/t Ag in the
Chalcocite Zone; all at a cut-off grade of 0.30% 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.
