Monroe Minerals Releases Lake Sediment Sampling Results From Alexis River Uranium Property in Labrador

CALGARY, ALBERTA--(Marketwire - April 23, 2008) - Monroe Minerals Inc. (TSX VENTURE:MMX) ('Monroe') announced today encouraging results from the follow-up lake sediment sampling program at Alexis River in south-eastern Labrador, Canada. The program was designed to evaluate anomalies from prior Geological Survey of Canada ('GSC') lake sediment-water sampling and the helicopter borne radiometric and magnetometer survey completed by the project operator, Altius Resources Inc. (TSX:ALS) ('Altius'), in late July 2007.

The Alexis River property was initially staked by Altius in 2004 based on a GSC lake sediment sample from a small lake (hereafter called Anomaly Lake) that contains 926 to 1,030 parts per million (ppm) uranium (fluorimetric versus INAA analysis). This site was the most anomalous of 18,640 lake sediment samples in Labrador taken by the GSC and Newfoundland & Labrador Department of Natural Resources of which the average uranium content is 3.8 ppm uranium.

During August and September 2007, Altius conducted (a) limited follow-up prospecting over selected airborne radiometric anomalies and (b) additional lake sediment sampling of Anomaly Lake. Anomalously radioactive outcrops and boulders were identified immediately west and east of Anomaly Lake. Anomalous radioactivity is locally up to 12,000 counts per minute (Exploranium GR-135 differentiating spectrometer) in coarse grained pegmatite. Assays of four rock samples from the radioactive occurrences west of Anomaly Lake range up to 204 ppm U (INAA analysis).

Fifteen lake sediment samples which were collected and analyzed by INAA during Fall 2007 provided initial verification of the existence of exceptionally high uranium and some other metals at Anomaly Lake, including 323 to 2,370 ppm uranium (average is 721 ppm U or 0.085 wt.% U3O8) and 175 to 1,070 ppm molybdenum. These results have been subsequently confirmed by further systematic lake sediment sampling that Altius and Monroe conducted in February 2008. Twenty-one samples from the February exploration have results ranging from 261 to 2,290 ppm uranium (average is 578 ppm U or 0.068% U3O8) and hence show excellent reproducibility of the uranium results from the fifteen previous sample locations. These results in tabular form are:

Winter 2008              21         2,290          261            578

---------------------------------------------------------------------

These lake sediment sample results for uranium are unusually high, being well over two orders of magnitude higher than the average uranium content of lake sediment samples within Labrador. The radioactive occurrences discovered to date in the vicinity of Anomaly Lake are encouraging but do not provide a satisfactory explanation for the very anomalous uranium content in these lake sediments. A comprehensive geological mapping, prospecting and sampling program is being planned for June to August 2008.

Reg A. Olson, Ph.D., P. Geol. is the designated Qualified Person for Monroe on the Alexis River project. Lake sediment and rock samples collected during 2007 were analyzed by INAA at Activation Laboratories Ltd. of Ancaster, Ontario. Lake sediment samples collected during February 2007 were analyzed by aqua regia digestion followed by ICP-MS/ICP-AES at ALS Chemex in Vancouver, British Columbia.

Monroe may earn a 60% interest in the Alexis River property over four years by spending $1,250,000 on exploration and making share payments to Altius of 2,500,000 Monroe shares.
