METALEX RECOVERS LARGEST DIAMOND YET FROM U2

KELOWNA, BC, May 16 /CNW/ -- 
KELOWNA, BC, May 16 /CNW/ - Metalex Ventures Ltd. (TSXV : MTX) ("Metalex", the "Company") is pleased to report the
 recovery of a 1.25 carat diamond from U2 along with diamond results
 from both the 9.3 hectare U2 kimberlite pipe and the 3 hectare T1 pipe
 on the Metalex - Arctic Star Diamond Corp. (TSXV : ADD) joint venture
 in the James Bay lowlands, Ontario.


U2 Kimberlite Results


A 1.25 carat, clear white diamond with a few minute inclusions has been
 recovered from hole U2-RC-06.  A picture of the diamond is presented on
 the Company's website (www.metalexventures.com).  This diamond exceeds the two 0.72 carat diamonds previously
 reported.


Primary recovery of diamonds from the fifth and sixth holes is now
 complete.  U2-RC-06 and U2-RC-07 contain 170 and 115 commercial sized
 stones (greater than 0.425mm) respectively.  Both holes intersected
 several blocks of limestone within the kimberlite which diluted the
 diamond grade over these sections.  These limestone blocks are
 interpreted to be large pieces of wall rock that fell into the
 kimberlite pipe at the time of eruption.  If U2 were to be mined, these
 limestone sections would be consigned to the waste dump.


The geology and diamond results for U2-RC-06 are presented in the
 following table:

Audit sample results from fine DMS tailings have been received from
 holes U2-RC-03 and U2-RC-04 where one and six diamonds were recovered
 respectively.  The additional diamonds recovered from U2-RC-04 increase
 the grade to 18.4 cpht and the number of diamonds to 87 from the 135 to
 240 meter interval (initial diamond results were reported in a March
 11, 2011 news release).  Audit samples have not yet been tested for
 holes U2-RC-05 to U2-RC-07 and these results could further improve the
 grade of these holes.


The size distribution of the diamonds is very coarse with a high
 proportion of the diamonds being in the large size categories.  This is
 important for a high average carat value.  The following table contains
 the size distribution of the diamonds recovered and described to date:

To date, as presented in the above table, 49.6% of the diamonds are
 white; 25.6% are grey; 16.7% are brown; 7.1% are yellow; 0.6% are pink
 and 0.4% are green. The proportion of white diamonds continues to
 improve with increasing diamond size.  Of the 53 largest diamonds
 (greater than 1.7mm), 37 are white, 1 is yellow, 10 are grey and 5 are
 brown.  By weight, white diamonds comprise 61.8% of the parcel and
 yellow, pink and green diamonds comprise 6.0%.


T1 Kimberlite Results


Results are now available from the final hole at T1.  Hole K06-05
 intersected kimberlite from a depth of 140 meters to 326 meters.  From
 326 meters to the end of hole at 335 meters granite was intersected
 which is interpreted to be the wall rock of the kimberlite.


The sample from the depth of 290 to 293 meters contained 249 diamonds
 greater than 0.425mm in size weighing a total of 0.70 carats whereas
 three meter samples from the remainder of the hole averaged 9
 diamonds.  Most of the diamonds contained in this sample are of similar
 colour and show breakage surfaces, suggesting that a large diamond was
 broken either during drilling or processing. It is important to note
 that many of the pieces of the broken stone would have been smaller
 than 0.425mm and thus would not have been recovered.  The results of
 the hole are presented in the following table:

A total of 20 holes comprising a bulk sample of 410 tons of kimberlite
 have now been processed.  From these 20 holes 12,446 commercial sized
 diamonds (greater than 0.425mm) have been recovered totaling 67.32
 carats.


The size distribution for the 20 hole bulk samples from T1 is presented
 in the following table:

As presented in the above table, 29.9% of the diamonds are white, 1.1%
 are green, 0.22% are blue, 0.1% are pink and 0.05% are yellow.


Five samples of -2.0mm DMS tailings from T1 were submitted for audit
 analysis at the CF Mineral Research Ltd. laboratory to test whether or
 not all of the diamonds were being recovered by the plant from the T1
 kimberlite.  No diamonds were recovered from two of the samples
 (weighing 181kg and 391kg respectively); two diamonds were recovered
 from each of two samples (weighing 159kg and 208kg respectively), and
 one diamond was recovered from a 180kg sample.  One diamond was a gem
 quality -1.18mm +0.85mm oval (tetrahexahedron) and the other four
 diamonds were -0.6mm +0.425mm in size. Three of these were brown and
 one is white.


Metalex is now considering reprocessing +1.0mm or +2.0mm DMS tailings
 from T1.  Diamonds recovered would add to the overall diamond grades
 and possible economic viability of T1.


Metalex is most encouraged as many of the large diamonds recovered to
 date from the very large 9.3 hectare U2 kimberlite are spectacular. 
 The results continue to support Metalex's belief that U2 contains a
 very high quality coarse diamond population.  Metalex looks forward to
 the diamond results from the remaining five 22cm diameter reverse
 circulation drill holes.


The technical information and results reported here have been reviewed
 by Mr. Chad Ulansky P.Geol., a Qualified Person under National
 Instrument 43-101, who is responsible for the technical content of this
 release.
