Independent Mine Development Study Supports 120,000-Ounce per Year Heap-Leach Mine for Jinshan's CSH '217' Gold Project, China; Final Feasibility Study Underway

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 26, 2005) - Jinshan Gold Mines Inc. (TSX VENTURE:JIN) announced today that the findings from an independent Mine Engineering and Development Study support the development of a commercial mining operation at the CSH (217) gold project in Inner Mongolia, China. The current study indicates that the planned mine would be capable of producing approximately 120,000 ounces of gold a year for the first 7.5 years at a cash cost of approximately US$232 an ounce. A final feasibility study is now underway and is expected to be completed by the second quarter of 2006.

The Mine Engineering and Development study was prepared by KD Engineering of Tucson, Arizona, to a pre-feasibility standard pursuant to Canada's National Instrument 43-101. Contributing consultants include Golder Associates Ltd., of Vancouver, Canada, Nilsson Mine Services, of Vancouver, Canada, Geosystems International of Florida, USA, and the Beijing General Institute of Mining and Metallurgy (BGRIMM), China.

The mine development schedule in the study calls for the mining of shallow (40-70 metres) run-of-mine (ROM) oxide mineralization for the initial two to three years of production, before bringing the deeper sulphide mineralization into production. After year two, a crushing circuit would be incorporated into the mining operation to improve the leach recoveries of gold contained in the sulphide resources.

The study indicates that the mine is capable of producing 120,000 ounces a year for an initial 7.5-year mine life. Using a base case gold price of US$400 per ounce, the project is forecast to generate a pre-tax internal rate of return of 30% and a net present value (NPV) discounted at 5% of US$62.3 million over the initial 7.5 years. The NPV over the same period at a 10% discount rate is US$37.4 million. The initial capital cost for the ROM development is estimated at US$31.8 million. Additional capital of US$21.9 million would be funded through cash flow from operations for the crushing circuit and additional heap-leach pad capacity.



The main conclusions of the study are:

- Pre-production Capital US$ 31.8 million (Includes 17% contingency)

- Recovery
- Oxides ROM 80%
- Oxides crushed 90%
- Sulphides crushed 70%
- Recovered Ounces 929,000
- Overall Strip Ratio 0.96 to 1

The Mine Development Study is preliminary in nature and there is no certainty that the results of this study will be realized. The qualified person responsible for preparing the study is Joseph Keane, a registered professional metallurgical engineer and President of KD Engineering.

The study was based on the project's April, 2005, independently estimated measured and indicated resources, which total 82.7 million tonnes grading 0.82 grams per tonne (g/t) gold, containing 2.2 million ounces of gold. The project also contains inferred resources of 36.5 million tonnes grading 0.89 g/t gold, containing an additional 1.0 million ounces of gold; however, the inferred resources were not included in the current economic analysis.

The resource estimate uses a 0.5 g/t gold cut-off and is fully diluted to accommodate a bulk mining production plan. Details of the estimate are in the company's news release dated April 19, 2005, and a Technical Report filed on SEDAR on same date. The estimate was calculated by Mario E. Rossi, MSc., Min. Eng., of GeoSystems International Inc., Florida, USA, a qualified person as defined by National Instrument 43-101. Mineral resources that are not reserves do not have demonstrated economic viability.

Jinshan is currently undertaking a 4,500-metre drilling program designed to upgrade the project's inferred resources to the measured and indicated categories. Step-out drill holes also are planned over the next few weeks with the goal of extending mineralization to the north, south and to depth.

Development Strategy

Jinshan will continue to equity fund engineering and critical path lead-time items until a final feasibility study can be completed and a mining permit is granted. The feasibility study is expected to be completed in the second quarter of 2006, at which time Jinshan plans to explore debt-financing options. An accelerated fast-track schedule has been prepared for the Development Study, which targets the commencement of commercial production in the second half of 2006.



Project Milestones

An 110KV power line is expected to be installed by the local government to the village of Xinhure, approximately 13 kilometres from the project, by the end of 2005.

Environmental Assessment

Hydrological drilling and assessment is underway under the supervision of Golder Associates Ltd., of Reno, Nevada. Jinshan's objective is to develop and operate the project in full compliance with international best practices for environmental protection and monitoring.

Mining

Heap-leaching of approximately 100,000 tonnes of mineralized material placed on the leach pads during last year's trial-mining program has been ongoing since May, 2005. To date, approximately 1,500 ounces of gold have been produced from the pilot-mining operations.

The mine development study envisions a heap-leach processing rate of 20,000 tonnes per day. Near-surface material has been weathered along gold-bearing fractures and is classified as oxide. At depth, the gold is associated with sulphide mineralization. During the initial two years of the mine plan, resources will be delivered run-of-mine to the heap-leach pad. A three-stage crushing plant is expected to be built in Year 2 to process primarily sulphide resources beginning in Year 3 through to the end of the mine life.

During the life of the mine, the study indicates that approximately 53 million tonnes of mineralized rock will be placed upon the heap for processing. Approximately 50 million tonnes of waste rock will be placed upon waste dumps. The overall strip ratio is 0.96 (waste rock) to 1 (mineralized rock).

Processing

The process for gold recovery has been designed as a heap-leach operation utilizing a multiple-lift, single-use leach pad. Both ROM and crushed mineralized rock will be hauled by truck and placed on the pad. Solution to leach the gold will be distributed by a buried drip-irrigation system. The solution will collect in a double-lined pond designed to operate in harsh winter conditions and be pumped to a process plant inside a heated building. Precious metals will be recovered from the leach solution in a carbon adsorption plant and the gold and silver recovered will be refined into a dore bars.

Project Ownership

On September 8, 2005, Jinshan announced that it had reached an agreement-in-principle with Ivanhoe Mines Ltd. to acquire Ivanhoe's 50% participating interest in the CSH (217) Gold Project in China. The transaction also terminates certain existing contractual arrangements whereby Ivanhoe has the right to participate with Jinshan in future mineral exploration and development opportunities in China. Under the terms of the agreement-in-principle, Jinshan will acquire all of Ivanhoe's participating interest in the CSH (217) Gold Project, that is currently a 50/50 Jinshan/Ivanhoe joint venture, all of Ivanhoe's interests in other joint venture arrangements between the parties, Ivanhoe's existing contractual rights to participate with Jinshan in new projects in China and cash proceeds of US$4.0 million from Ivanhoe in exchange for the issuance to Ivanhoe of 48,552,948 Jinshan common shares.

Ivanhoe is the largest shareholder, currently owning approximately 38.5% of Jinshan's outstanding shares. If the transaction is completed, Ivanhoe would increase its ownership to approximately 69.3%.

The proposed transaction is a "related party transaction" and is subject to approval by a majority of the votes cast at a shareholders' meeting by Jinshan's minority shareholders and receipt of all required regulatory approvals and other customary conditions. Neither Ivanhoe nor certain Jinshan shareholders who are related parties of Ivanhoe will be entitled to vote on the transaction.

If the transaction is completed, Jinshan will have a 96.5% interest in the CSH (217) Project and Ningxia Nuclear Industry Geological Exploration Institute will have the remaining 3.5% carried interest.
