The Indicated Copper Resources at Far West's Santo Domingo Property in Chile Have Increased by 58% to 2.85 Billion Pounds

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 6, 2007) - Far West Mining Ltd. (TSX:FWM) is pleased to announce that it has received NI 43-101 compliant resource estimates from Scott Wilson Roscoe Postle Associates Inc. (Scott Wilson RPA) on the Santo Domingo Sur, Iris and Estrellita copper deposits located in the Santo Domingo District of northern Chile (Region lll), approximately 800km north of Santiago.

Please note that the Indicated Resources reported in the text of this release are all presented at a 0.3% Cu cut-off unless otherwise noted.

Highlights

- The Indicated Resources at Far West's Santo Domingo Property in Chile have increased by 58% to 2.85 billion pounds of copper since the initial Indicated Resource was reported in May 2006.

- The Indicated Resource of the Santo Domingo Sur deposit has increased from 139.4 Mt grading 0.59% copper and 0.08 gpt Au to 171.5 Mt grading 0.57% copper and 0.08 gpt Au.

- The Indicated Resource of the Iris deposit, which adjoins Santo Domingo Sur on the northeast border, is 31.2 Mt grading 0.46% copper and 0.06 gpt Au.

- The Indicated Resource of the Estrellita deposit, located some 4km to the northwest of Santo Domingo Sur, is 31.7 Mt grading 0.55% copper and 0.05 gpt Au.

The Scott Wilson RPA Technical Report on the Mineral Resource Estimates will be filed on Sedar within 45 days.

Santo Domingo Sur & Iris Deposits

The Indicated Resource for the Santo Domingo Sur deposit has increased from 139.4 Mt grading 0.59% copper to 171.5 Mt grading 0.57% copper since the initial resource estimate was published in May 2006. The Indicated Resource estimate for the Iris deposit, which adjoins the Santo Domingo Sur deposit and has similar geological and mineralogical characteristics, is 31.2 Mt grading 0.46% copper.

The Santo Domingo Sur and Iris deposits will be combined for the Scoping Study (Preliminary Economic Assessment) that has been initiated to investigate their economic viability. The scoping study is scheduled to be completed during the first quarter of 2008. The Indicated Resources of the two deposits contain in excess of 2.478 billion pounds of copper and 493,000 ounces of gold.

The Santo Domingo Sur deposit has a near-surface high grade core of mineralization along its southern margin where numerous drill intercepts exceed grades of 0.70% copper (See Figure 2). The high grade zone presents an attractive entry point to commence mining.

Estrellita Deposit

The Estrellita deposit, an east-west striking, flat to shallow dipping tabular body is located approximately 4km to the northwest of Santo Domingo Sur (See Figure 1 and 3). The style of mineralization at Estrellita is different from the latter, hosting a significant near-surface oxide component that may be amenable to leaching. Metallurgical studies are underway to determine the copper oxide, oxide/sulphide and sulphide horizons in the deposit and related copper recoveries. Timely receipt of this data will determine if Estrellita can be included in the scoping study currently underway for Santo Domingo Sur and Iris. Drill holes for which assays were received subsequent to the completion of the resource estimation, are not included. At least eight holes will add to the Estrellita resource and will be included in the next estimation. The Estrellita deposit remains open to the west, southwest and northeast and these areas will be drill tested when drilling resumes.

The exploration potential of the Santo Domingo Property (200 square kilometres) remains high and the Company anticipates future exploration drilling in an effort to add to the outlined resources.

Resource Estimates

The current mineral resource estimates for Santo Domingo Sur and Estrellita are based on 3-dimensional block models with individual zones interpreted from both lithology and grade envelopes using an external cut-off of approximately 0.15% Cu for Santo Domingo Sur and 0.1% Cu for Estrellita. Specific gravity, used to convert volumes to weights, was based on regression formulas developed by Scott Wilson RPA using Fe as the independent variable.

The tables in this release set out the quantities and grades for the Indicated and Inferred classifications as estimated by Scott Wilson RPA. Grade interpolation was done using Ordinary Kriging (OK). The models for Santo Domingo Sur were constructed using MINESITE software, and for Estrellita using GEMS.

The estimate is based on the results from 308 drill holes. The drill spacing averages just over 100 m in Santo Domingo Sur and Iris, and 50m in Estrellita. In Scott Wilson RPA's opinion, this is sufficient to classify the majority of the resources as Indicated. Those mineral resources classified as Indicated are located within the core of the drilling while the Inferred mineral resources are located along the periphery and at depth where the holes did not pierce the lower horizons.

In order to reduce the influence of statistically anomalous sample data on resource estimations, a number of higher-grade assay values are often capped prior to compositing at levels determined by various means including examination of probability distribution data. Scott Wilson RPA produced a series of lognormal probability curves for copper and gold within the interpreted zones to examine the distribution of the assay data. The distribution curves for Santo Domingo Sur and Iris exhibited breaks or inflections points at or about 3.5% Cu and 0.52 g/t Au indicating several distinct populations for each metal.

The Estrellita data do not display distinct inflections at the high end of the distributions, and so the caps were established at the 99th percentile. These values were at 3% for Cu and 0.3 ppm for Au. All data were capped prior to compositing.

This news release contains certain statements that may be deemed "forward-looking statements". All statements in this release, other than statements of historical fact, that address future production, reserve potential, exploration drilling, exploitation activities and events or developments that the Company expects to occur, are forward looking statements. Although the Company believes the expectations expressed in such forward-looking statements are based on reasonable assumptions, such statements are not guarantees of future performance and actual results may differ materially from those in the forward-looking statements. Factors that could cause the actual results to differ materially from those in forward-looking statements include market prices, exploitation and exploration successes, and continued availability of capital and financing, and general economic, market or business conditions. Investors are cautioned that any such statements are not guarantees of future performance and actual results or developments may differ materially from those projected in the forward-looking statements. The Company does not assume any obligation to update or revise its forward-looking statements, whether as a result of new information, future events or otherwise.

This news release uses the terms "inferred resources", "indicated resources", "measured resources", and "mineral resources". The Company advises investors that although these terms are recognized and required by Canadian securities regulations (under National Instrument 43-101 "Standards of Disclosure for Mineral Projects"), the US Securities and Exchange Commission does not recognize these terms. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. In addition, "inferred resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be assumed that any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, or economic studies except for a Preliminary Assessment as defined under National Instrument 43-101. Investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
