Quantum Cites 2011 Niobium Drill Results in Nebraska as Key Milestone
and Announces Preliminary Niobium Economic Assessment Planned for
2012
December 20, 2011 – Vancouver, B.C. Quantum Rare Earth Developments Corp. (the
“Company” or “Quantum”) (TSX.V – QRE, FSE – BR3, OTCQX – QREDF) President and Chief
Executive Officer, Peter Dickie, recapped the Company’s 2011 activities at its Annual General
Meeting held on Monday, December 12, 2011.
This news release provides a summary of Mr. Dickie’s overview of the Company’s activities
during the 2011 year.
Key Milestone
During the 2011 year, the Company released data showing a large, indicated resource at its 14-
square mile site at Elk Creek, Nebraska (the “Elk Creek Project”) of 80.1 million tonnes of
niobium grading 0.62% Nb2O5 (see news release dated April 28, 2011 for more information).
Quantum aims to be the solution for America’s strategic and critical niobium needs for the
domestic steel and aviation industry by developing one of the richest niobium deposits in the
world and the only significant deposit in America. Niobium is crucial in jet thrusters, steel for
bridges, buildings, oil and gas pipelines, stainless steel, and MRI machines.
2011 Highlights
March 2011
 Release of a National Instrument 43-101 Standards of Disclosure for Mineral Projects
(“NI 43-101”) resource report on the Elk Creek Project, showing an inferred resource of
80.1 million tonnes grading 0.62% Nb2O5 (containing an estimated 493 million kilograms
of Nb2O5. (See news release dated April 28, 2011 for more information)
April 2011
 Commencement of first drill program at Elk Creek Project in over 25 years
July 2011
 Announcement of Niobium zone drill results, with NEC11-01 targeting an infill zone
where the NI 43-101 report on the Elk Creek Project previously did not have any credits
toward the total resource. Grades reported were 235 meters of 0.73% Nb2O5, including
54 meters grading 1.17% Nb2O5 (see news release of July 27, 2011 for more
information)

news release dated August 16, 2011 for more information); and
 Signing of metallurgical testing agreement with Hazen Research Inc. (“Hazen”) to test
niobium recoveries from recently drilled core
September 2011
 Announcement of drill results from Rare Earth zone (located 2.5 kilometers east of
niobium zone at Elk Creek Project), including NEC 11-004 returning 236 meters grading
2.1% TREO*, including 68 meters grading 3.32% *TREO (See news release dated
September 20, 2011 for more information)
November 2011
 Completion of option agreements divesting Australian and Ontario properties, furthering
the Company’s ability to concentrate on Elk Creek Project
December 2011

Also in June 2011, Quantum made significant additions to its board of directors and advisory
board, through the additions of David Beling, P.E., Jim Reynolds, Chemical Engineer and David
Shoemaker, Mining Engineer.
Looking forward to 2012, Mr. Dickie advised shareholders of several key milestones the
Company is aiming to complete, including:
 receipt of metallurgical testing results from Hazen;
 engagement of an outside engineering firm to complete an updated resource calculation
and preliminary economic assessment work on the niobium deposit;
 additional infill drilling to elevate the deposit towards the indicated and measured
category;
 further discussions with potential off-take or strategic partners to accelerate development
of the Elk Creek Project; and
 enhancement of the technical management team overseeing the Elk Creek Project.
In closing, Mr. Dickie added, “We are particularly proud of the accomplishments made by our
development team this year on the Elk Creek deposit. We are well-positioned to reach the next
level of development of our large niobium resource, and our dedicated development team
continues to work hard towards achieving these goals.”
