January 12, 2009 – Todd Creek

PolarStar Mining — Mon, 12 Jan 2009 17:35:31 +0000

TORONTO, ON, January 12, 2009 – Polar Star Mining Corporation (TSXV:POS) (“Polar Star” or the “Company”) and its partner, Goldeye Explorations Limited (“Goldeye”) and the optionor, Intuitive Exploration Inc. (“NTE”), are pleased to announce the discovery of a significant volcanogenic massive sulfide (VMS) environment on the Todd Creek Property in northwest British Columbia, Canada. BC Geological Survey geologists have confirmed the favorable environment, which has been traced via the presence of VMS stratigraphy, stringer/feeder zones and multiple exhalite horizons, in outcrop and new drillholes over a strike length of more than 7 km. Sampling of the discovery outcrop in 2008 returned assays up to 57 g Ag/T, 1.7% Cu and 7.1% Zn. The partners have optioned additional ground to cover the apparent strike extension of one of the VMS horizons, bringing the total land position to nearly 20,000 hectares.

Core drilling in 2008 at the South Zone Au-Cu target returned an interval of 1.75 g Au/T and 0.26% Cu over a 17.3m core length. Assays have not been delivered for the bottom portion of that first hole or the seven additional holes from the 2,600 meter program. Historic drilling at the South Zone included a number of strong intercepts, including 8.62 g Au/T and 0.45% Cu over 11.7m. Subsequent drilling at South Zone in 2008 encountered VMS-style mineralization, for which assays have not yet been returned. NTE geologists have interpreted the South Zone as occupying an important structural intersection that may constitute a feeder to VMS stratigraphy and a conduit for later crosscutting epithermal or porphyry-related Au-Cu mineralization. Most of the analytical results from 2008 drilling and surface geochemistry have been put on hold at the lab pending the restructuring of Intuitive Exploration Inc. (NTE), the private company operating the exploration program, which cost approximately $2.2 million in 2008.

The Todd Creek Property is located in Skeena Mining Division in the Eastern Volcanic Belt of the Stewart Gold Camp of British Columbia. There remain numerous other gold, copper, and VMS targets to be delineated when results from 2008 are complete. NTE is contemplating the 2009 exploration program to follow up on these successes. The program may include an airborne electromagnetic/magnetics survey, ground geophysical surveys, mapping/sampling, and diamond drilling. The property is held by Polar Star and Goldeye, and NTE has the right to earn up to a 70% interest with expenditures of $5 million and certain option and share payments. NTE expended approximately $2.2 million in exploration during 2008.

January 12, 2009 – Montezuma

PolarStar Mining — Mon, 12 Jan 2009 17:33:47 +0000

TORONTO, ON– January 12, 2009 Polar Star Mining Corporation (TSXV: POS) (“Polar Star” or the “Company”) announces an exploration update on its Montezuma property which is believed by the Company to have the potential to host large porphyry copper deposits. Reconnaissance geological mapping, rock and soil sampling by Polar Star staff and a 119 line kilometre pole-dipole Induced Polarisation (IP) survey conducted on behalf of Polar Star by Quantec Geoscience, Santiago, Chile have now been completed.

Highlights:
Montezuma
• Old workings, leached and oxide copper bearing outcrops, geological and geochemical surveys define a highly prospective belt 5-8 kilometres wide by 30 kilometres long centred on the West Fault System.
• A large Chargeability/Resistivity anomaly 0.8 to 2.3 kilometres wide, 23.5 kilometres long, extending to depths of at least 300 to 500 metres has been identified by the Quantec IP survey within this belt, along with several other 2- 4 kilometre long satellite anomalies.
• The length of the main IP anomaly is greater than all the known Chuquicamata porphyry copper deposits combined.
• Property consists of 43,200 hectares, and is located 30 kilometres due south of CODELCO’s Chuquicamata Mine and Smelter Complex; and,
• Covers 25 km of the West Fault System and associated splays, which hosts many large porphyry copper deposits including Chuquicamata and Escondida.

The Montezuma Project

The Montezuma Project consists of a contiguous group of 100% owned exploration concessions staked by Polar Star. As noted above, the West Fault System is well known for the exceptional tonnage and quality of its deposits. The Chilean Mine Handbook reported that in 2007 the BHP/RTZ owned Escondida Mine produced 1.5 million tonnes of copper and had copper reserves of 4.3 billion tonnes at an average grade of 0.81% Cu. The Corporaciόn Nacional del Cobre’s (“Codelco”) El Norte Division, which includes Chuquicamata, reported production of 0.9 million tonnes of copper, reserves of 2.3 billion tonnes and an average grade of 0.79% Cu during the same period.

The Montezuma Project is located in the Sierra Limon Verde oxide copper mining district and is readily accessible by paved and good gravel road from the city of Calama, 20 kilometers to the north. The project consists of three groups of exploration concessions; Montezuma, Topater and Limonal totaling 43,200 hectares staked and owned 100% by Polar Star.

The Property lies within the central sub-zone of the main Chilean porphyry belt and covers approximately 25 kilometres of strike of the West Fault System and associated sub-parallel and NW-SE cross-cutting ancillary faults. The hills of Sierra Limon Verde which cover the Limonal, north and west half of the Montezuma claims generally expose the same group of metamorphosed Paleozoic intrusive, volcanic and sedimentary rocks that host the Chuquicamata porphyry copper deposits. The rest of the Montezuma claims and most of the adjacent Topater claims are covered by pediment gravels derived from the local hills.

Polar’s geological and geochemical surveys to date have identified several large areas of leached, hematite stained and sulphate rich caps containing minor amounts of copper wad and chrysocola developed along and lateral to the West Fault System where it strikes through the northern claims of the Montezuma group and within the Topater group, quartz-tourmaline-copper-gold veins and stockworks of the type commonly found peripheral to porphyry systems. In addition on several of the IP lines, 1-2 metre deep pits dug for electrodes uncovered disseminated copper minerals in porphyritic intrusive rocks.

There are no public records of mining or exploration activity in the property area. There are however three groups of old drill holes reportedly drilled by Codelco in the central and southern part of the Montezuma property along the projection of the West Fault System. Cuttings from a number of these holes show propylitic to phyllic alteration assemblages containing disseminated and veinlet pyrite plus minor chalcopyrite and bornite.

The reconnaissance IP survey was concentrated along a NNE trending belt some 6-9 kilometres wide covering the trace of the West Fault System and adjacent N-NNE trending splays and cross faults and detected several anomalies. The main anomaly, which is entirely covered either by a sulphate cap or pediment gravels is 0.8 – 2.3 kilometres wide, 23.5 kilometres long and extends to depths of at least 300-500 metres. The central sector of the anomaly straddles the West Fault but to the north and south it appears to be controlled by NNE trending splay and cross faults. By comparison the length of this main anomaly is greater than the combined known Chuquicamata porphyry copper deposits from Radomiro Tomic to Toki (see attached map).

Mr. Terence Walker, M.Sc., P.Geo., is the qualified person within the meaning of National Instrument 43-101. Mr. Walker has reviewed the contents of this news release. The forgoing comments and interpretation of the IP survey results are based on local knowledge and experience of Polar Star’s personnel. The Quantec final report and recommendations are still in preparation.

Polar Star Completes Phase I Due Diligence Drilling

at the Chépica Project

TORONTO, ON, January 8, 2009 – Polar Star Mining Corporation (TSXV POS) (“Polar Star” or the “Company”) announces final results from sixty-five shallow diamond drill holes totalling 6,758 meters completed in late November 2008 on the Chépica No.1 and No.2 Vein systems as part of its ongoing due diligence review of the Chépica mining property and mill (the “Chépica Project”), Talca, Region VII, Chile. Results from the first 30 holes were the subject of Polar Star’s October 22, 2008 press release with the remainder covered by this release.

Highlights

· 49 holes totalling 5,274 meters on the Chépica No.1 Vein system, covering 330 meters of strike and to 180 meters depth.

· 16 holes totalling 1,484 meters on Chépica No.2 Vein system, covering 150 meters of strike and to 125 meters depth.

· Drilling on the Chépica No.1 Vein system demonstrates this system has good lateral and vertical continuity and contains at least 3 strong veins with true widths typically ranging from 2 meters to over 12 meters.

· Drilling on the Chépica No.2 Vein system also shows multiple veins, however they are more irregular and true widths typically range from 1.5 meters to 8 meters.

· Merging of individual veins to form composite veins from 5 meters to over 20 meters true width is common to both systems.

· Weighted average grades from the individual veins include highs of 12.8 g/t gold plus 1.96% copper over 2 meters to 31.67 g/t gold plus 0.78% copper over 3 meters width from the Chépica No.1 Vein system and 2.2 g/t gold plus 3.97% copper over 2 meters to 4.96 g/t gold plus 1.17% copper over 3 meters from the Chépica No.2 Vein.

· Weighted average grades from composite veins include highs of 3.37 g/t gold plus 0.56% copper over 21 meters to 2.1 g/t gold plus 0.7% copper over 45 meters from the Chépica No.1 Vein and 2.4 g/t gold plus 1.39% copper over 5 meters to 1.81 g/t gold + 3.32% copper over 9 meters from the Chépica No.2 Vein.

· The sulphide flotation mill began on-going sampling and testing of operations in mid November 2008 and is now processing an average of 50 tonnes per day from the Chépica No.2 Vein system. The mineralized material being shipped to the smelter grades from 25% – 29% copper and 30 – 45 g/t gold.

· The Chépica Project operator is currently planning to increase mill throughout to at least 150t/d by mid-March, 2009.

Diamond Drill Results (see Summary Table attached)

Diamond Drilling Program

The 65 hole due diligence diamond drilling complete to date consists of:

a) A series of fourteen fences of three or four holes each drilled along approximately 330 meters of strike of the Chépica No.1 Vein system, the first twelve fences being spaced approximately 25 meters apart and the two southern most fences at 50 meters spacing. The holes within each fence test the Chépica No.1 Vein system at 25 meter intervals from 25 meters to 150 meters below the 125 meters main adit level, assays from which were previously reported (see October 22, 2008 press release).

b) A series of six fences of two or three holes each drilled along approximately 150 meters of strike of the Chépica No.2 Vein system, the fences being spaced approximately 25 meters apart. The holes within each fence test the Chépica No.2 Vein system at 25 meter intervals from 25 meters above to 75 meters below the 130 meter main adit level.

This program was designed to confirm and extend a copper-gold resource reported by ENAMI in 2005 that exists below the Chépica No.1 and Chépica No.2 main adits. Individual samples within the vein system intersected were selected based on vein characteristics. The intercept values reported in the table are weighted averages.

All but six of the Chépica No.1 drill holes and three of the Chépica No.2 drill holes cut what the Company believes are good grades of gold and copper over potentially mineable widths, the details of which can be found in the attached table. This drilling also demonstrates that the Chépica No.1 Vein system has good continuity and contains at least 3 strong on-echelon veins, nominally denoted as hanging wall, central and footwall veins in the attached table. Their widths typically range from 3 meters to over 12 meters. However, in holes 12, 17, 23, 25, 26, 35 and 54 two or more veins merge to form composite veins over 20 meters wide. The Chépica No.1 Vein system is open to extension along strike and to depth. The drilling on the Chépica No.2 Vein system also shows multiple veins; however, they are more irregular and widths typically range from 1.5 meters to 8 meters true width and can also merge to form composite veins up to 10 meters width. Plan sections of the No.1 Vein will be posted to the Polar Star website (www.polarstarmining.com). Attached is a map of the Chépica No.1 Vein system drill program.

The Company is continuing surface exploration of the five other gold and/or copper-gold bearing vein systems on the Chépica Project and 15 additional targets on its adjoining wholly owned Corinto and Batuco claims.

The Chépica Project

Polar Star currently owns a 15% equity interest in the Chépica Project and has the right to acquire the remaining 85% of the Chépica Mine by making cash payments totalling 2.7 billion Chilean Pesos (approximately US$ 4.3 million) by June 20, 2009, pending successful completion of its final due diligence review.

This Chépica Project adjoins Polar Star’s wholly owned Corinto and Batuco claims. These claims plus the Chépica Project total 16,640 hectares in the Pencahue District, Region VII, Chile on which prior exploration by other companies has defined 15 gold and copper-gold zones. The Chépica Mine is currently being developed, by its current operator, to achieve a planned initial production of 200 tonnes per day increasing to over 500 tonnes per day by late 2009. Readers are cautioned that a feasibility study has not been completed and there is no certainty the proposed operations will be economically viable.

The Chépica Mine property, located 225 kilometres south of Santiago, near the city of Talca, covers the Cerro Chépica copper-gold mining district. It is readily accessible by paved and good gravel road from the city of Talca 20 kilometres to the east. See Polar Star’s news release of April 24, 2008 for additional information.

NI 43-101 Report

Polar Star has retained the services of SRK Consulting’s Santiago office (see October 22, 2008 press release) to prepare a National Instrument 43-101 compliant report on the Chépica No.1 Vein system property and to subsequently develop a mine plan.

Qualified Person

Mr. Terence Walker, M.Sc., P.Geo., is the qualified person within the meaning of National Instrument 43-101. Mr. Walker has reviewed the contents of this news release. Individual core samples were halved using a diamond core saw, one half bagged and sealed on site for assay the other half retained on site in sealed metallic core boxes for future reference. All analyses were carried out at ALS Patagonia Laboratories, Coquimbo, Chile. Routine gold analysis was carried out on 30g sub-samples using a fire assay pre-concentration and atomic absorption spectro-photogrametric (AAS) finish. Samples with values greater than 10g/t were re-analysed by fire assay and gravimetric finish. Silver and copper were also routinely analysed by ICP following hot four acid digestion. Samples with copper values over 1% were re-analysed using a hydrofluoric-nitric-hypochloric acid digestion, hydrochloric acid leach and AAS finish.

PolarStar Mining — Tue, 23 Dec 2008 15:10:26 +0000

TORONTO, ON, November 19, 2008 – Polar Star Mining Corporation (“Polar Star”) has re-negotiated its option to purchase agreement on the Chépica mining property and mill (the “Chépica Project”) whereby Polar Star can now take operational control of the project and has three years to the pay the balance of the purchase price. Polar Star expects to complete documentation and closing of this restructured deal during December 2008. The modified agreement terms are: 1) Polar Star will purchase an additional 5% equity of the Chépica Project for CP$150 million (approximately US$236,000 under today’s current exchange rates); 2) the remaining balance of the previously agreed purchase price will be increased by 20% at closing; and, 3) Polar Star has the option to pay this balance in part or in full at any time from the profits of any mining and milling operations which may occur over the next three years. There are no minimum cash amounts that are required to be paid during the three year period and Polar Star will be the sole operator. Closing will be subject to receipt of the usual regulatory approvals.

On November 14, 2008, as part of their on-going sampling and testing of operations on the Chépica N°2 Vein, the current owner/operators of the Chépica Project shipped 22 tonnes of test material from their onsite flotation mill to the Empresa Nacional de Minería, Chile (“ENAMI”) smelter at Valparíso. Their planned production rate of 200 tonnes per day is expected to be reached by the second quarter of 2009.

Polar Star’s initial 5,000 metre drill program at the Chépica Project is scheduled to be completed on or about November 30, 2008.

There is no current NI 43-101 compliant resource report on the Chépica Project however SRK International will be incorporating these results in a National Instrument 43-101 compliant report which is expected to be delivered in the first quarter of 2009.

PolarStar Mining — Wed, 22 Oct 2008 17:23:01 +0000

TORONTO, ON, October 22, 2008– Polar Star Mining Corporation (TSXV:POS) (“Polar Star” or the “Company”) announces preliminary results from the first thirty diamond drill holes completed on the Chépica N°1 Vein system as part of its ongoing due diligence review of the Chépica Mine property, Talca, Region VII, Chile. Drilling continues on the Chépica N°2 Vein system. The sulphide flotation plant installation at the Chépica Mine is complete with commissioning to start before October 31.

Highlights

· 30 diamond drill holes totalling 3,415 meters completed to date on the Chépica N°1 Vein system covering 280 meters of strike and 150 meters depth. Drilling on Chépica N°2 Vein system has commenced.

· These drill holes demonstrate that the Chépica N°1 Vein system has good lateral and vertical continuity and contains at least 3 strong veins with widths typically ranging from 2 meters to over 12 meters.

· In drill holes 12, 17, 23, 25, 26 and 35, two or more veins merge to form composite veins over 20 meters wide.

· Weighted average grades from the individual veins include highs of over 2 meters of 12.8 g/t gold plus 1.96% copper to 3 meters of 31.67 g/t gold plus 0.78% copper.

· Weighted average grades from composite veins include highs of over 21 meters of 3.37 g/t gold plus 0.56% copper to over 45 meters of 2.1 g/t gold plus 0.7% copper.

· A mill has been installed on site and commissioning has commenced to produce a copper – gold concentrate from the Chépica N°2 adit.

Diamond Drill Results (see Summary Table attached)

Diamond Drilling Program

These initial thirty diamond drill holes complete a series of eleven fences of two-three holes drilled along approximately 280 meters of strike of the Chépica N°1 Vein system. The first ten fences were spaced at about 25 meters apart and fence number eleven was spaced 50 meters south of fence number 10. The holes within a fence test the Chépica N°1 Vein system at 25 meter intervals from 25 meters to 100 meters below the main adit level, assays from which were previously reported (see July 8, 2008 press release). This program was designed to confirm and extend a copper-gold resource reported by ENAMI (Empresa Nacional de Minería, Chile) in 2005 to exist below this adit. Individual samples within the vein system intersected were selected based on vein characteristics. The intercept values reported in the table are therefore weighted averages.

All but three of these drill holes cut, what management believes, are good grades of gold and copper over potentially mineable widths, the details of which can be found in the attached table. This drilling also demonstrates that the Chépica N°1 Vein system has good continuity and contains at least 3 strong on-echelon veins, nominally denoted as hanging wall, central and footwall veins in the attached table. Their widths typically range from 2 meters to over 12 meters, however, in holes 12, 17, 23, 25, 26 and 35 two or more veins merge to form composite veins over 20 meters wide. The Chépica N°1 Vein system is open to extension along strike to the south and to depth.

The Company continues to drill fences across the Chépica N°2 Vein system with the same objectives as the first phase drilling recently completed on the Chepica N°1 Vein system i.e. confirm and extend a copper-gold resource reported by ENAMI (Empresa Nacional de Minería, Chile) in 2005 to exist above and below the Chépica 2 adit.

The Chépica Mine

Polar Star currently owns a 15% equity interest in the Chépica Mine and has the right to acquire the remaining 85% of the Chépica Mine by making cash payments totalling 2.7 billion Chilean Pesos (approximately US$ 4.4 million) by June 20, 2009, pending successful completion of its final due diligence review.

This Chépica Mine acquisition adjoins Polar Star’s wholly owned Corinto and Batuco claims. These claims plus the Chépica Mine property total 16,640 hectares in the Pencahue District, Region VII, Chile on which prior exploration by other companies has defined 15 gold and copper-gold zones. The Chépica Mine is currently being commissioned to achieve a planned initial production of 200 tonnes per day increasing to over 500 tonnes per day by mid 2009. The Chépica Mine will produce a copper-gold concentrate.

The Chépica Mine property, located 225 kilometres south of Santiago, near the city of Talca, covers the Cerro Chépica copper-gold mining district and is readily accessible by paved and good gravel road from the city of Talca 20 kilometres to the east. See Polar Star’s news release of April 24, 2008 for additional information.

NI 43-101 Report

Polar Star has retained the services of SRK Consulting’s Santiago to prepare a National Instrument 43-101 compliant report on the Chepica N°1 Vein system property, which is expected to be delivered within the next 3 months.

Qualified Person

Mr. Terence Walker, M.Sc., P.Geo., is the qualified person within the meaning of National Instrument 43-101. Mr. Walker has reviewed the contents of this news release. Individual core samples where halved using a diamond core saw, one half bagged and sealed on site for assay the other half retained on site in sealed metallic core boxes for future reference. All analyses were carried out at ALS Patagonia Laboratories, Coquimbo, Chile. Routine gold analysis was carried out on 30g sub-samples using a fire assay pre-concentration and atomic absorption spectro-photogrametric (AAS) finish. Samples with values greater than 10g/t were re-analysed by fire assay and gravimetric finish. Silver and copper were also routinely analysed by ICP following hot four acid digestion. Samples with copper values over 1% were re-analysed using a hydrofluoric-nitric-hypochloric acid digestion, hydrochloric acid leach and AAS finish.

PolarStar Mining — Thu, 25 Sep 2008 15:59:46 +0000

TORONTO, ON– September 24, 2008 Polar Star Mining Corporation (TSXV:POS) (“Polar Star” or the “Company”) announces an exploration update on its Montezuma copper porphyry and Chépica Copper-Gold Mine projects.

Highlights:

Montezuma

· Old workings, geological and geochemical surveys define a highly prospective belt 2-5 km wide by 30 km long centred on the West Fissure Fault System.

· A large I.P. Chargeability/Resistivity anomaly 1 to 1.6 kilometres wide, 12 kilometres long, extending to depths of at least 300 to 350 metres has been identified by the ongoing geophysical survey within this belt, along with several other Chargeability/Resistivity anomalies (see attached Montezuma Project map).

· Property consists of 43,200 hectares, and is located 30 km due south of Codelco’s Chuquicamata Mine and Smelter Complex.

· Covers 25 km of the West Fissure Fault System and associated splays, which hosts many large porphyry copper deposits including Chuquicamata (see attached Codelco North Division map) and Escondida.

Chépica Mine

· 28 diamond drill holes completed to date on the Chépica N°1 Vein system covering 270 metres of strike and to 150 metres depth (see attached Chépica N°1 Vein map). Drill results are expected to be released during the fourth quarter. Drilling on Chépica N°2 vein system has commenced.

· The system demonstrates good continuity and contains at least 3 strong veins with widths from 3 metres to over 20 metres.

· A mill has been installed on site and commissioning has commenced to produce a copper – gold concentrate.

The Montezuma Project

The Montezuma Project consists of a contiguous group of 100% owned exploration concessions staked by Polar Star. As noted above, the West Fissure Fault System is well known for the exceptional size of its deposits. The Chilean Mine Handbook reported that in 2007 the BHP/RTZ owned Escondida Mine produced 1.5 million tonnes of copper and had copper reserves of 4.3 billion tonnes at an average grade of 0.81% Cu. The Corporaciόn Nacional del Cobre’s (“Codelco”) El Norte Division, which includes Chuquicamata, reported production of 0.9 million tonnes of copper, reserves of 2.3 billion tonnes and an average grade of 0.79% Cu during the same period.

The Property lies within the central sub-zone of the main Chilean porphyry belt and covers approximately 25 km of strike of the West Fissure Fault System and associated sub-parallel and NW-SE cross-cutting ancillary faults. The hills of Sierra Limon Verde which cover the Limonal, north and west half of the Montezuma claims generally expose the same group of metamorphosed Paleozoic intrusive, volcanic and sedimentary rocks that host the Chuquicamata porphyry copper deposits. The rest of the Montezuma claims and most of the adjacent Topater claims are covered by pediment gravels derived from the local hills.

Polar’s geological and geochemical surveys to date have identified several large areas of leached, hematite stained and sulphate rich caps containing minor amounts of copper wad and chrysocola developed along and lateral to the West Fissure Fault System where it strikes through the northern claims of the Montezuma group and within the Topater group, quartz-tourmaline-copper-gold veins and stockworks of the type commonly found peripheral to porphyry systems.

There are no public records of mining or exploration activity in the property area. There are however three groups of old drill holes of unknown origin in the central and southern part of the Montezuma property along the projection of the West Fissure Fault System. Cuttings from a number of these holes show propylitic to phyllic alteration assemblages containing disseminated and veinlet pyrite plus minor chalcopyrite and bornite.

On-going Induced Polarisation-Resistivity surveys along a belt some 6-7 kms wide covering the trace of the West Fissure Fault System and adjacent N-NNE trending splays and cross faults have detected several anomalies. The main anomaly, which is entirely covered either by a sulphate cap or pediment gravels is 1.2 – 1.6 kilometres wide, to date is over 12 kilometres long and extends to depths of 300-350 metres. It straddles the West Fault to the south but to the north follows two sub-parallel cross faults which trend NNE towards the copper bearing veins and stockworks.

The Chépica Mine

Polar Star currently owns a 10% equity interest in the Chépica Mine and will purchase a further 5% for 150 million Chilean Pesos (approximately US$282,000) on or about September 26, 2008. Polar Star has the right to acquire the remaining 85% of the Chépica Mine by making cash payments totalling 2.7 billion Chilean Pesos (approximately US$ 5.1 million) by June 20, 2009, pending successful completion of its final due diligence review.

This Chépica Mine acquisition adjoins Polar Star’s wholly owned Corinto and Batuco claims. These claims plus the Chépica Mine property total 16,640 hectares in the Pencahue District, Region VII, Chile on which prior exploration by other companies has defined 15 high grade gold and copper-gold zones (see attached Talca Property map). The Chépica Mine is currently being commissioned to achieve a planned initial production of 200 tonnes per day increasing to over 500 tonnes per day by mid 2009. The Mine will produce a copper-gold concentrate.

The Chépica Mine property, located 225 kilometres south of Santiago, near the city of Talca, covers the Cerro Chépica high grade copper-gold mining district. It is readily accessible by paved and good gravel road from the city of Talca 20 kilometres to the east. See Polar Star’s news release of April 24, 2008 for additional information.
