Iron Metallurgical Test Work Confirms Magnetite Recovery at Far West Mining's Santo Domingo Project

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 03/15/11 -- Far West Mining Ltd. (TSX: FWM) is pleased to announce that additional iron metallurgical test work at SGA continues to return positive results. Magnetite recovery from the rougher flotation tailings of the new composite, representative of the initial five years of production, confirms that a high grade magnetite concentrate can be produced. Test work has been completed in both fresh and sea water, with concentrate grades being marginally lower in sea water (1% Fe) than corresponding results in fresh water. Optimisation to address the variance, which is considered related to additional carryover of silica in seawater, is in progress.
Far West Mining ('the Company') contracted SGA (Studiengesellschaft fur Eisenerzaufbereitung GmbH & Co. KG) to conduct iron metallurgical test work on rougher flotation tailings samples resulting from the copper test work program being undertaken at SGS in Lakefield, Ontario (refer to press release of February 24, 2011). The composite, designed to be representative of the first five years of production at Santo Domingo, has an average grade of 29% Fe, and has been used for metallurgical process development such as determination of regrind sizing, copper flotation conditions, and the development of the magnetite separation circuit.
The iron test work follows on from the previously announced copper rougher flotation test work using a primary grind of 175 microns in sea water. The material was subjected to staged magnetic recovery to simulate plant conditions. The magnetite recovery has confirmed all prior test work and established that a high grade magnetite concentrate can be produced. Minor additional silica entrainment within the magnetite concentrate is observed in sea water processing resulting in slightly lower (1%) iron grades. Work is now focused on reducing this effect. A direct relationship exists between grind size and iron concentrate grade which is related to silica liberation. The attached graphs show the ability to produce an iron concentrate varying between 64 and 68% Fe with increasing fineness of grind and that overall iron recovery is not materially impacted. This flexibility will enable the project to optimise product specifications to match market conditions.
Results from variability tests currently in progress will be used to construct a grade-recovery curve for iron that will be included in the ongoing Pre-Feasibility Study for Santo Domingo. Metallurgical test work also continues on hematite composites aimed to provide a process route that can be incorporated into the flow sheet to further enhance iron recoveries.
The Company is working with SGA to complete the program in a timely basis. Results will be reported when they become available.

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. Forward looking statements are statements that are not historical facts and are generally, but not always, identified by the words 'expects', 'plans' 'anticipates', 'believes', 'intends', 'estimates', 'projects', 'potential' and similar expressions, or that events or conditions 'will', 'would', 'may', 'could' or 'should' occur. Information inferred from the interpretation of drilling results and information concerning mineral resource estimates may also be deemed to be forward looking statements, as it constitutes a prediction of what might be found to be present when and if a project is actually developed. 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. Forward-looking statements are based on the beliefs, estimates and opinions of the Company's management on the date the statements are made.
