West High Yield Updates Status of Anticipated Preliminary Economic Assessment

CALGARY, ALBERTA--(Marketwire - March 8, 2013) - As first disclosed by West High Yield (W.H.Y.) Resources Ltd. (TSX VENTURE:WHY) (the "Company") in 2009 and on September 29, 2011, October 27, 2011 and in a number of subsequent news releases, the Company commissioned SRK Consulting of Lakewood, Colorado ("SRK") to prepare a Preliminary Economic Assessment ("PEA") in respect of the Company's Rossland, British Columbia magnesium property (the "Record Ridge South Property"). Completion of the PEA required the completion of extensive metallurgical test work and the Company engaged Met-Solve Laboratories Inc. ("Met-Solve") of Vancouver, British Columbia to continue metallurgical test work to compliment work previously performed and to provide results to SRK for incorporation into the PEA. The Company expects to be in a position and has undertaken to provide the PEA in early May this year following completion of the additional metallurgical test work and a technical review by the Company.

The Company further advises that it missed meeting the previously reported PEA delivery date because of delays with the final stages of metallurgical testing specifically related to magnesium recovery. Met-Solve conducted test work to evaluate the potential of using a hydrometallurgical process to extract magnesium from mineral samples provided by the Company. This process allowed for the conversion of magnesium to a marketable product. The program was designed to evaluate the parameters which affect the amount of magnesium extracted via acid leaching, slurry neutralization and impurity removal. The metallurgical test work focused on optimization of the extraction process and improving the grade and purity of the end product which was magnesium oxide ("MgO"). MgO is the raw material required to further produce magnesium.

To date, under the preferred leach conditions, an average of 62.6% magnesium was leached into solution and recovered. The barren solution contained 18.9% of the total magnesium which was lost to wash water and some of which may be potentially recoverable via recirculation. Further testing is yet to be completed and the Company anticipates that improved magnesium recoveries will be achieved and form the basis for economic models in the PEA. The current 62.6% average magnesium recovery supports reasonable prospects of economic extraction and magnesium resource estimates. The economic models within the PEA are very sensitive to the magnesium recovery rate and the Company anticipates that the additional required testing may allow for material positive change in the PEA model assumptions used by SRK in the final PEA.

The PEA is expected to reflect additional work that was recommended to be undertaken in the Company's "NI 43-101 Technical Report on Resources, West High Yield (W.H.Y.) Resources Ltd., Record Ridge South, Rossland, British Columbia" prepared by SRK, SRK Project Number 183201 dated February 11, 2009 (the "2009 SRK Report"), which is available on SEDAR at www.sedar.com.
