Hana Mining Reports On Drilling And Exploration Activities At Ghanzi Copper-Silver Project In Botswana
DIAMOND DRILLING FURTHER EXTENDS COPPER SILVER MINERALIZATION ALONG NORTH AND SOUTH LIMBS OF ZONES 1 and 2
REINTERPRETATION OF AIRBORNE GEOPHYSICAL SURVEYS IDENTIFY SECOND MINERALIZED HORIZON - COMBINED HORIZONS NOW TOTAL 1,100 KILOMETERS OF STRIKE LENGTH
MICON INTERNATIONAL CONFIRMS CERTAIN HISTORCAL DRILL DATA CAN BE USED FOR FUTURE RESOURCE ESTIMATIONS
Vancouver, BC, October 1, 2008 -- Hana Mining Ltd. (TSX-V: HMG) (Frankfurt -- 4LH) is pleased to report an update of corporate activities and exploration at its sediment-hosted Ghanzi Copper-Silver Project in Botswana. Assay results for 26 diamond drill holes collared along the North Limb of Zone 1 and South Limb of Zone 2 have been received. Twelve of the holes were drilled along the south limb of Zone 2 which has now been defined along a 3.7 kilometer strike length and the remaining fourteen holes were drilled along a 2.4 kilometer strike length at the north limb of Zone 1. The holes at Zone 1 are 5.0 kilometers southwest of previously reported diamond drilling (press release of May 8, 2008) and 12.0 kilometers northeast of a new discovery reported from percussion drilling (press release of July 29, 2008) (See attached Map and Web Link at http://www.hanamining.com/i/pdf/b_wrevised_jta.pdf). This is the first drilling carried out by Hana Mining in this area. An additional 33 diamond drill holes have been completed at Zones 1 and 2 and results are pending.

Twin Hole Program
The initial stages of the drilling campaign, which started in August 2007, were focussed on twinning 5 RC holes and 2 diamond drill holes carried out by Delta Gold and Anglo American, respectively as stated in the NI 43-101 Technical Report. (See report at -- http://www.hanamining.com/i/pdf/TechnicalReport.pdf). The goal of the twin hole program was to verify mineralization and determine whether this data could be incorporated into the drill hole database for future resource estimation. An assessment of the twin hole program was carried out by Micon International. The study noted that there is good correspondence of the thickness and location of the mineralized intervals between the holes; however, the grade of the RC holes was higher than the corresponding diamond drill hole. Micon concludes "...that the data from the RC and Anglo core holes can be used for Inferred resource estimation. The RC sample data will likely need a top-cut applied to remove the risk of bias. This top-cut can be derived from statistical analysis of sample populations from new drilling." The net effect of this study is that Hana Mining can now incorporate 27 additional RC holes and at least 20 diamond drill holes into a database for resource estimation.
Reinterpretation of Airborne Geophysics
The model for copper-silver mineralization at Ghanzi consists of copper sulphide minerals that occur immediately above the contact between a lower oxidized sandstone FW (foot wall) and upper reduced siltstones HW (hanging wall). This mineralized horizon has been repeated across the property due to folding along northeast trending axes. The main tool for delineating these folds and attendant potential horizons is government aeromagnetic and EM data. This data has been reprocessed and interpreted resulting in the identification of two mineralization target types; the typical HW -- FW type can be traced over a 600 kilometer cumulative strike length, and an intra-hanging wall type that occurs above the HW-FW type, that can be traced over a 560 kilometer cumulative strike length. Collectively, these two mineralization targets represent over 1160 kilometers of cumulative strike length which equates to only 1.5% of the entire property as being drill tested.

BANKABLE FEASIBILITY STUDY INFILL DRILLING AT BOSETO COPPER PROJECT CONFIRMS PLUTUS MINERAL RESOURCE COPPER‐SILVER GRADES AND MINERALISED WIDTHS: Press Release September24, 2008
• 13 drill holes within the existing Plutus Inferred Mineral Resource envelope. All returned
significant results including:
𐂃 Hole PSDD280 6.5 metres @ 2.1 % Cu & 24.6g/t Ag, including
3.5 metres @ 3.0% Cu and 37.8g/t Ag
𐂃 Hole PSDD282 13.0 metres @ 2.0 % Cu & 20.4g/t Ag, including
3.0 metres @ 4.6 % Cu & 32.0g/t Ag
𐂃 Hole PSDD288 11.6 metres @ 1.5 % Cu & 12.5g/t Ag, including
1.6 metres @ 5.5% Cu and 33.3g/t Ag
𐂃 Hole PSDD289 6.0 metres @ 1.5 % Cu & 16.0g/t Ag
• Mineralised intersections generally exceed the average width of the existing Plutus
interpretation
• Plutus Mineral Resource still open at depth and to the south west
• Plutus infill drilling forms part of BFS and confirms continuity and robustness of the Mineral Resource
Discovery Metals Limited (ASX/BSE: “DML”) (AIM: “DME”) announces the results of the latest thirteen infill drill holes. The intersected mineralisation typically contains above average widths and grades. All holes were drilled within the Plutus prospect at the company’s 100% owned Boseto Copper Project in north west Botswana (Figure 1). These latest results will be incorporated into the current Bankable Feasibility Study (BFS) targeted for completion in mid 2009.
The Plutus prospect currently contains an Inferred Mineral Resource of 14.5Mt @ 1.3% Cu and 13 g/t Ag at a cut off grade of 0.6% Cu and along with the Zeta and Petra prospects forms the currentMineral Resource base for the Boseto Copper project which currently has a total Indicated andInferred Mineral Resource of 49Mt @ 1.2% Cu.
These results represent a continuation of the diamond drilling programme designed to drill Plutus on 200 metre spaced sections. The existing Plutus Inferred Mineral Resource, reported in 2007, is defined by drill holes with an average drill hole section spacing of approximately 500 metres. The Plutus Mineral Resource remains open at depth and to the south west. The deepest hole drilled at Plutus to date (PD028‐07) delineated mineralisation at 175 metres below the surface.
Assay results from the latest 13 drill holes demonstrate the high degree of continuity of the coppersilver mineralisation across the Plutus resource and also demonstrate that substantial areas exist where the mineralisation is significantly wider than previously identified. Discovery Metals’ Managing Director, Mr Brad Sampson said, “Each new round of assay results from our drilling programme reinforces the continuity of the mineralisation over extensive strike lengths at Boseto. The increased data density we have obtained from this programme will allow better definition of the thicker and higher grade zones of mineralisation as well as progressing our understanding of the drill spacing required to upgrade the Inferred Mineral Resource categorization on the existing resources, including the newly discovered Quirinus mineralisation.” He added, “This information will be incorporated into the upgraded Plutus Mineral Resource model
which I anticipate being completed in October 2008“.

Regional Exploration Success at the Quirinus Prospect - Press Release
• All three holes Reverse Circulation (RC) drilled in the Quirinus Prospect have intersected
copper – silver mineralisation.
• Assay results include:
-4m @ 1.7% Cu and 13g/t Ag; and
-6m @ 0.9% Cu and 14g/t Ag, including 2m @ 1.5% Cu and 25g/t Ag.
• These results reinforce the copper-silver prospectivity of the Discovery Metals 6,400 km2, 100% owned tenement package in north west Botswana.
• A diamond drill programme has commenced to enable definition of the intersected
mineralisation.
• The Quirinus prospect contains approximately 40 strike kilometres of potentially copper–silver mineralised stratigraphy.
Discovery Metals Limited (ASX/BSE:”DML”, AIM:”DME”) has announced results from the first three
exploration drill holes into the Quirinus prospect (Figure 1). The Quirinus prospect is located 15 kilometres from the current mineral resources at Zeta, Plutus and Petra in north west Botswana.
Results include 4m @ 1.7% Cu and 13g/t Ag and 6m @ 0.9% Cu and 14g/t Ag including 2m @ 1.5% Cu and 25g/t Ag (Table 1). These three holes were all drilled by the reverse circulation method to a maximum down hole depth of 90 metres. Previous studies of the nearby Zeta, Plutus and Petra Inferred Mineral resources have shown that holes drilled by the reverse circulation method can underestimate the copper grade of the mineralisation.
Surface geochemical sampling has previously defined a 3,300 metre long copper anomaly at Quirinus. The results announced today confirm the presence of potentially economic mineralisation over the 600 metres of this anomaly that has now been drill tested. The prospect remains open along strike to both the northeast and southwest and at depth. Historic geochemical results suggest the anomaly in this portion of the Quirinus prospect could extend to greater than 6,000 metres along strike. A regional soil geochemical survey is being undertaken in this area to better define the lateral extents of this anomaly.
A diamond drilling program similar to those used to define the Zeta, Plutus and Petra Inferred Mineral
resources is also underway at Quirinus to define any potential mineral resource.
Discovery Metals’ Managing Director, Mr. Brad Sampson, said, “To date we have been drilling in areas which will allow us to fast track the development of a significant copper mine at Zeta, Plutus and Petra (Inferred Mineral Resource of 46.1 Mt at 1.3% Cu). We have now successfully taken the knowledge and experience gained during this work into our regional exploration programme and have already identified another very prospective green field area at Quirinus. We believe that these results reinforce the potential for finding further mineralization within Discovery Metals’ entire tenement package in north west Botswana. We know of a number of historic geochemical copper anomalies which have not been drill tested including a number in relatively close proximity to the existing Inferred Mineral resource at Zeta, Plutus and Petra”. “We believe that we are exploring in an emerging and significant copper province”, he said.
