Cue Resources Ltd. Receives Positive Pump Test Results at the San Antonio Uranium Deposit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 13, 2011) - Cue Resources Ltd. (TSX VENTURE:CUE) ("Cue" or the "Company") is pleased to announce positive results from the recently completed pump test on the Company's San Antonio uranium deposit, at the Yuty Project, in Paraguay. Based on the aquifer properties and recovery and injection rates, along with previously reported successful metallurgical testing (see release dated March 17, 2009), these results indicate that the uranium at San Antonio can be extracted using the ISR (In Situ Recovery) process.

"These results met our expectations, by confirming previous laboratory testing, and support our efforts to advance the project as an in situ recovery operation," stated Chris Healey, P.Geo, & Director. "We have demonstrated that lixiviant (a liquid medium used to selectively extract uranium from ore bodies) can be pumped through the aquifer at commercial rates allowing excellent retention time for the lixiviant to contact the uranium and aid in an efficient extraction process."

The purpose of the pump test was to determine the properties of the sandstone that hosts the aquifer and the uranium deposit. Previously reported laboratory testing indicated that the aquifer has similar properties to several commercial in situ leach uranium operations in the Powder River Basin in Wyoming.

The test was carried out by pumping water out of one well, and observing the drawdown and the rate of recovery in seven surrounding wells, for a total of six days (one day pre-pumping monitoring, two days of pumping and three days of recovery). The results show connection between the pumping well and each monitoring well, even to the farthest well at a distance of 157m.

The transmissivities calculated from the aquifer test by the straight-line method ranged from 2.3 to 6.7m2/day, with an average of 3.7m2/day. The average hydraulic conductivity based on the aquifer thickness of 46m (151 ft) was computed from the average transmissivity and is 0.07m/day (0.25 ft/day). This hydraulic conductivity is comparable to hydraulic conductivities at several commercial ISR projects in the Powder River Basin in Wyoming.

The field work, data analysis and reporting were carried out by Hydro Engineering LLC of Casper, Wyoming.

San Antonio Deposit

The San Antonio Deposit consists of a current NI 43-101 compliant resource, Indicated, 9.0M tonnes @ 0.042% eU3O8 containing 8.3M lbs eU3O8 and an Inferred Resource of 1.1M tonnes @ 0.050% eU3O8 containing 1.2M lbs eU3O8. Column leach tests have demonstrated recovery of up to 86% of the contained uranium from cores taken from San Antonio.
