Superior Initiates Diamond Drill Program, Canopener Gold Joint Venture, Lansdowne House Area, Northwestern Ontario

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 14, 2007) - Superior Diamonds Inc. (TSX VENTURE:SUP) ("Superior" or the "Company") is pleased to announce commencement of a first phase diamond drill program on its 50%-owned Canopener Property, located near Lansdowne House, Northwestern Ontario. Superior's joint venture partner is Lake Shore Gold Corp.(1). This program was initiated once an agreement was reached with the Neskantaga First Nation, upon whose traditional territory the Canopener property occurs.

As previously reported, the interest in this area for gold was sparked by the recovery of anomalous numbers of total gold grains from overburden samples, including anomalous values of pristine gold grains. (Gold, being relatively soft, remains as pristine grains for only a short distance from its source.) These samples, part of a regional sampling program, were originally collected to evaluate the area for its diamond potential. When Superior analysed the results of the overburden sampling program, it identified two significant and well defined gold grain dispersal trains. In addition, there were several single samples with anomalous gold grain values that did not appear to be associated with dispersal trains.

These anomalous gold grain values are associated with shear structures that occur within the Peeagwon metavolcanic assemblage of the Wunnummin Greenstone Belt. This belt is considered under-explored for gold. The Canopener property strategically covers a significant area of these shear structures from which the individual anomalous gold grain values and gold grain dispersal trains are thought to have been derived and within which several gold showings have been previously identified.

This purpose of this first phase of diamond drilling is to gain a better understanding of the local geology and to test some of the gold showings. Nine to twelve holes are planned and drilling should be completed by mid- to late July. A program to collect 200 to 250 overburden samples is planned to follow, for completion by mid-August. The purpose of this program is to: a) determine if there are other gold grain dispersal trains on the Canopener property, and b) determine if the single samples with anomalous gold grain values are part of other gold grain dispersal trains. Once the data from the first phase of diamond drilling and overburden sampling has been compiled and interpreted, Superior is anticipating a more extensive diamond drill program in early 2008.
