Rockex Drills 524.3 Metres at 29.93% Iron Underneath Currently Defined 43-101 Compliant Resource Outline

 THUNDER BAY, ONTARIO--(Marketwire -11/30/11)- Rockex Mining Corporation (TSX: RXM.TO - News) ("Rockex" or the "Company") is pleased to announce assay results from the current 2011 fall drilling program on its 100% owned Western Lake St. Joseph project in north-western Ontario, Canada.

Drill Hole EI-106

Hole EI-106, with a direction of 320 degrees and a dip of -70 degrees, was drilled to intersect at depth the Main Zone North (or 'MZN') of the Eagle Island Deposit in the Company's Western Lake St Joseph project; the drill hole was ended at 987.8 metres. The bulk of the Iron formation was intersected from 337.7 metres in-hole (265 metres vertical depth) to 862 metres in-hole (564 metres vertical depth). The true width of the mineralized intersection is estimated at 495 metres. The assay results are:

EI-106 337.7 862 524.3 29.93

Donald A. Sheldon, Chief Executive Officer of Rockex, commented on these results, saying "It is exciting to see the large width and consistent grade of the iron mineralization at depth, up to 190 metres directly below the outlined resources. Follow-up drilling and additional results will be used to update and upgrade the current resource estimate."
As of today, a total of nine (9) drill holes totalling 4,720.2 metres have been completed out of 8,000 metres planned for the current drilling campaign. The drilling program started at the Eagle Island Deposit with a view to upgrading the classification of various parts from Inferred Resources to Measured and Indicated Resources and adding to the estimated size of the deposit. The program will test both the anomalies identified in the Company's recent airborne survey (including Fish Island) and the mineralized zone at Eagle Island at depths below 300 metres. Two drills are currently active on the property.

Samples were prepared on-site from sawn NQ2 gauge drill core. Blanks and duplicate assays are included at regular intervals in each sample batch submitted to SGS Mineral Services in Lakefield, Ontario. Assay protocol includes major element oxides by X-Ray Fluorescence, Total Sulfur and Carbon by LECO induction furnace with Infrared finish, titration of Fe2+ reported as FeO and Satmagan saturation magnetic assay to report magnetic iron content. As of today, the Company has only received a complete set of XRF assays for one drill hole, EI-106. Further detailed reporting of the results will be issued as the Company receives additional assay results from the laboratory.

The project is composed of 27 contiguous mining claims covering an area of 6,864 hectares. The Western Lake St. Joseph project hosts a NI 43-101 resource estimate with Indicated Resources of 590,847,000 Tonnes at 28.84% Soluble iron (%SFe) and Inferred Resources of 415,757,000 Tonnes at 29.47% SFe using a cut-off grade of 18% SFe. These resources currently reach a vertical depth of 374m.
