QUANTUM Commences Drilling at the Archie Lake Property

September 27, 2010 – Vancouver, B.C.:  Quantum Rare Earth Developments Corp. (TSX.V – QRE, FSE – BR3, OTCQX – QREDF) (“Quantum”, the “Company”) is pleased to announce that it has mobilized field crews for the fall 2011 fall drill program at the Archie Lake Rare Earth Property, located in northern Saskatchewan

The program will include twelve to eighteen holes totaling 1,200 metres, drilled from three pads.  The diamond drill holes are projected to range from 50 to 100 metres in order to define the depth extent of the surface mineralization.

To date, high-grade surface Rare Earth Element surface (“REE”) mineralization at the Archie Lake Property has been identified along a strike length of approximately 550 metres, with a width of up to 6 metres, and samples reaching up to 29.9% TREE* (see July 6, 2010 News). 

The surface mineralization has been exposed by several previously blasted trenches, and successively mapped and sampled by the company between 2009 and 2011.  The mineralogical work to-date has identified REE mineralization exclusively from the mineral monazite, thought to be of paleo-placer origin.

Peter Dickie, President of Quantum, comments: “We are very pleased to start our first drilling campaign at the Archie Lake Project.  The high-grade surface REE mineralization has been extremely encouraging, and we look forward testing the mineralization at depth”.

*TREE (Total Rare Earth Elements) is defined as the sum of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y.  Samples at Archie Lake are predominantly composed of the LREE (Light Rare Earth Elements), defined as the sum of Ce, La, Nd, Pr and Sm, which make up over 98% of the REE content.

Neil G. McCallum, P.Geo. is the qualified person responsible for the technical information in this news release.
