White Tiger Mining Corp.: "RM Discovery" Yields Wide Copper Zones at Marshall Lake Property, Ontario

WEST VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 20, 2011) - White Tiger Mining Corp. (TSX VENTURE:WTC)(FRANKFURT:W0I) -

Further to the Company's news releases of April 5 and April 11, 2011 (drilling results announced), White Tiger Mining Corp. (the "Company" or "White Tiger") is very pleased to report the assay results from drill hole RMZ11-21 for the Marshall Lake project in Ontario.

Drill hole RMZ11-21 was designed to test the western extension of the "RM Zone", which drill hole is located 300 metres southwest of the initial discovery (drill hole GAZN08-06 and follow up drill hole GAZN10-15, as referred to in White Tiger's news releases dated November 3, 2010 and April 5, 2011). The Company believes that the two mineralized zones intersected by drill hole RMZ11-21 indicate that the RM Zone extends along strike to the west and that the Lease Zone showing extends along strike to the east (which occurs 100 metres west of hole RMZ11-21).

The assay results for the RM Zone portion of drill hole RMZ11-21 are as follows:

Including15916018.8538.60.826
The true width of the mineralized zones is estimated to be 66% of the mineralized intersection.

Drill hole RMZ11-23 was collared 25 metres south and was drilled beneath drill hole RMZ11-21. Assays are pending for drill hole RMZ11-23 and will be released when received and reviewed by the Company. The reported mineralization supports the possibility of an eastward trend from the Lease Zone showing. The IP geophysical survey and core drilling completed in November 2010 indicate a potential strike length of 625 metres for the RM Zone (see news releases dated November 3, 2010 and November 17, 2010).

Drill core was split at the Marshall Lake property and sample preparation was done by ALS Chemex in Thunder Bay, Ontario. Pulp samples (<75 microns) were then sent by secure courier to ALS Chemex in North Vancouver, British Columbia and analyzed by ICP spectrometer ("ICP") using a 0.5g representative pulp dissolved in Aqua Regia (3 acid) digestion. All samples grading over 1.0% copper were re-assayed with ore grade ICP and Aqua Regia digestion. Gold analysis was done on a 30 gram sample by fire assay extraction with AA ("Atomic Absorption") finish.

The Marshall Lake Property is a copper, silver and gold exploration project located 30 km west of Nakina, Ontario, with access via good all weather gravel road from Hwy 11 (and 22 km north of the main CNR rail line).

White Tiger has the option to earn a 50% interest in the Marshall Lake project from Rainy Mountain Royalty Corp. ("Rainy Mountain") (TSX VENTURE:RMO) and Marshall Lake Mining PLC ("MLM") by spending $4 million in exploration expenditures over 5 years and issuing 2 million shares over 4 years to Rainy Mountain. As well, White Tiger has the additional option to increase its interest to 75% by incurring such additional expenditures as are necessary to take the project to bankable feasibility stage.

This news release has been reviewed and approved by Robert Middleton, P.Eng., who is acting as the Company's Qualified Person for the Marshall Lake property project, in accordance with regulations under NI 43-101.
