December, 2007 (VANCOUVER) – Hard Creek Nickel Corporation (TSX.V – HNC) today announced that AMEC Americas Limited (AMEC) has completed a positive Preliminary Assessment (the 'Study') of the Company’s 100% owned Turnagain Nickel Project, located near Dease Lake in British Columbia, Canada. The Study dated December 10, 2007 and entitled 'Updated Preliminary Assessment of the Turnagain Nickel Project', will be filed on SEDAR within 45 days and available at the same time for viewing on the company’s website www.hardcreek.com. The Study is based on a measured, indicated and inferred mineral resource estimate completed by AMEC. This estimate incorporates a revised and expanded geological interpretation of the Horsetrail zone and peripheral area which includes 19 drill holes from the 2007 drilling program. Timing of the Study did not allow the resource estimate to include an additional 32 infill and stepout holes for a total of 11,933 metres (39,150 feet) drilled in 2007. Samples from these drill holes have been prepared and are in the process of being analyzed. The Study initially considered nickel recovery by both the production of a saleable concentrate and a hydrometallurgical process. Completion of the study was based on the hydrometallurgical process option given its’ better economic viability. Results presented below are for the open pit mining and hydrometallurgical process scenario.

'Management is pleased with the results of the Study,' said Mark Jarvis, President of Hard Creek Nickel. 'Given recent escalating mine capital cost projections we are encouraged to find out that even with these increases the preliminary assessment came out positive with a mine life of 29 years. AMEC’s assessment indicates that the deposit is potentially mineable and has identified that further work is justified. Hard Creek will be undertaking additional work in all major areas to advance the project to the pre-feasibility level. Confirmation and availability of the required power for the project has also been identified by AMEC as critical. Hard Creek is aggressively pursuing all possible options for providing sufficient power to make the project feasible.' Hard Creek is waiting for analytical results from most of the 32 infill and stepout holes around the Turnagain deposit from the 2007 drilling program which were not included in the mineral resource estimate stated in the Study. These results are expected to increase the overall resource and upgrade the confidence level of a portion of the current inferred mineral resource. Analytical results from our drilling program will be released as they become available. An updated mineral resource estimate will be provided once all of the results have been received. Recent drilling results obtained since the closing date of the Study have already indicated the potential to include platinum and palladium as a portion of our overall Turnagain deposit resource (see news release dated November 28, 2007). These results were obtained within the limits of the ultimate pit identified in the Study. As previously stated, the potential to include platinum and palladium as a portion of our overall resource could be significant. Close spaced drilling will be required during the next drill season to determine the significance and extent of this mineralization. Turnagain Nickel Project Overview The Turnagain Nickel project, which is 100% wholly-owned by Hard Creek, is located in British Columbia about 1350 km (835 miles) northwest of Vancouver and 70 km (44 miles) east of Dease Lake. The property consists of 81 contiguous mineral claims covering an area of approximately 29,370 ha (72,570 acres). Nickel and copper sulfides were first identified on the property in about 1956 with Falconbridge Nickel Mines completing the first exploration programs during the period from 1966 to 1973. Exploration to date on the Turnagain property has included geological mapping, geophysical and geochemical surveys and more than 75,620 metres (248,100 feet) of diamond drilling in 304 drill holes. The total includes an additional 56 drill holes (32 infill and stepout holes from the Turnagain deposit and 24 exploration holes) which were completed since the closing date of the Study. Mineral Resources The updated mineral resource estimate for the Turnagain deposit was performed by Dr. Guillermo Pareja of AMEC under the guidance of Mr. Greg Kulla, P.Geo. of AMEC. A significant improvement between this estimate and previous estimates is the use of geologic domains in the model. Previous models, which used grade shells and did not have the benefit of a lithologic model, showed conditional bias and local excessive smoothing. The table below presents the estimate of the resource of the Turnagain Nickel deposit using a 0.10% NiS cut-off, as at September 25, 2007, of 489 million tonnes of Measured and Indicated Resources at 0.163% NiS and an additional 560 million tonnes of inferred Resources at 0.152% NiS. A total of 42,128 metres (138,215 feet) of diamond drilling in 158 drill holes were used in interpolating grade in the resource area. The mineral resources of the Turnagain deposit were classified in accordance with CIM Definition Standards and Best Practices referred to in NI 43-101 which have a reasonable expectation of economic extraction. The mineralization of the Project satisfies criteria to be classified into Measured, Indicated and Inferred mineral resource categories. If you can't view the table please go to www.hardcreeknickel.com Mineral Resource Estimate Table Cut-off Grade at 0.10% NiS Tonnage (thousands) % NiS % total Ni % Co Measured 59,464 0.184 0.250 0.011 Indicated 429,688 0.160 0.218 0.012 Measured + Indicated 489,152 0.163 0.222 0.012 Inferred 560,052 0.152 0.204 0.011 The sulfide nickel and cobalt grades are based on an analytical procedure employed by Acme Laboratories that consists of a concentrated hydrogen peroxide plus ammonium acetate leaching solution that is believed to be selective at dissolving nickel and cobalt from sulfide mineral species while leaving the nickel and cobalt in silicates undissolved. As a precautionary step all the sulfide nickel grades were assigned a value of zero if the corresponding sulphur assay was less than 0.2% S. Sulphur assays were based on Leco furnace method except for results obtained in 2006 which were ICP analysis. This precaution may cause an underestimation of the nickel resource and could be large enough to be a material impact. However, this approach limits the possibility that an overestimation of the nickel resource has occurred. Mining and Processing The mining assessment for the Turnagain nickel deposit is based on typical industry standards for a preliminary assessment study with regard to the nature and mineability of the resource. The Study initially considered nickel recovery by both the production of a saleable concentrate and a hydrometallurgical process. Completion of the Study was based on the hydrometallurgical process option given its’ better economic viability. The proposed mining operation is a conventional shovel and truck open pit mine feeding a 50,000 tonne per day process plant using standard mineral flotation technology. Throughput analysis was not performed as part of the Study. Mining and processing of the deposit will be initiated in a 'starter pit' which has been scheduled to maximize the production of high-grade material during the first five years, to shorten the capital payback period. Lower grade material from the starter pit will be stockpiled and fed to the mill in the later years of operation. The pit will expand in phased pushbacks until the ultimate pit limits are reached. The table below shows the contained tonnes and grade in the ultimate pit shell. About 67% of the mineral resource contained in the ultimate pit is in the Measured or Indicated category. If you can't view the table please go to www.hardcreeknickel.com Ultimate Pit Tonnes and Grade Table Cut-off Grade at 0.10% NiS Tonnage (thousands) % NiS % total Ni % Co Measured 56,611 0.187 0.252 0.012 Indicated 290,871 0.164 0.222 0.010 Measured + Indicated 347,482 0.167 0.227 0.010 Inferred 169,941 0.145 0.199 0.010 Material for processing will be hauled to a primary crusher located near the southwest rim of the Main Pit. The mine at the 50,000 tonne per day throughput has a potential life of 29 years with approximately 516.6 million tonnes at 0.160% NiS and 0.010% Co to the mill at an average stripping ratio of 0.44:1. The construction schedule is estimated at 24 months. Feed to the mill will be processed using a concentrator and hydrometallurgical process facility on-site to produce separate nickel and cobalt hydroxide products that will be trucked and shipped out of the province through the Port of Stewart, for sale to ferronickel producers. In addition, a separate copper concentrate will be produced which can be sold to a copper smelter. Processing will be based on a conventional nickel sulfide flotation flowsheet to produce a sulfide concentrate followed by a hydrometallurgical process to convert nickel and cobalt from its sulfide forms to a hydroxide form.

It was recommended that work in all major areas be undertaken to advance the project to the pre-feasibility level to better determine the economic viability of the project. This work includes drilling to better define the resources and upgrade these into reserves. More metallurgical work is necessary to ensure that saleable metal products can be produced. More environmental and geotechnical work is necessary to allow the project to move forward. The pre-feasibility study would examine variants to derive the appropriate path to the development of this deposit. Confirmation and availability of the required power from the North American grid is critical to this project.
