Heavy Rare Earth Oxide enrichment encountered in Niobium zone
July 27 2011 – Vancouver, B.C.: Quantum Rare Earth Developments Corp. (TSX.V – NB, FSE – BR3, OTCQX – NIOBF) (“Quantum”, the “Company”) is pleased to announce results for the first of five drill holes from the spring/summer 2011 exploration program at the Elk Creek Niobium – REE Project, located in southeastern Nebraska, USA.
Highlights from the current exploration include:
- NEC11-01: 235.22 m of 0.73% Nb2O5 and 0.43% TREO*,
- including 54.13 m of 1.17% Nb2O5 and 0.46% TREO; and
- the identification of a significant zone of Middle and Heavy Rare Earth (MHREO) mineralization of between 25%° to 35% MHREO*, with notable enrichment in Europium, Gadolinium, Terbium and Dysprosium, associated with the Elk Creek Niobium Deposit.
Drill hole NEC11-001 is one of five holes recently completed at the Elk Creek Project. Three holes were completed at the Elk Creek Niobium Deposit, one hole to the south of EC-93 (155.5 m of 2.7% TREO, see news release dated March 7, 2011), and one hole to test a unique aeromagnetic anomaly. For the remaining drill holes, results will be released upon their receipt. The company anticipates the resumption of drilling during early September.
Exploration at the Elk Creek Niobium Deposit was designed to accomplish several objectives:
1) Complete in-fill and step-out drilling, to potentially upgrade the current 43-101 Resource from Inferred to Indicated;
2) Expand the known niobium resource (News Release dated April28, 2011: 80 MT of 0.62% Nb2O5 at a 0.4% Nb2O5 cut-off); and
3) Collect sufficient sample material for the initiation of characterization and process development studies of niobium ore from Elk Creek.
Drill hole NEC11-001 was drilled at a -70° inclination at a direction of 035° to a depth of 900.38 metres (a drill plan and cross-section are available on the company’s website at http://www.quantumrareearth.com ). The hole was drilled within the southeastern portion of the deposit at depth; results of niobium and the rare earth elements and their ratios are as follows:
Based on the deposits geometry, the drilled thickness is currently estimated at 60 per cent of the true thickness.
The identification of a new zone of Middle and Heavy Rare Earth Oxide (MHREO) enrichment associated with the higher grade portions of the niobium interval was identified within drill Hole NEC11-001. This zone will be further investigated via a review of mineralogy and historic results to determine its significance.
*A rigorous quality assurance and quality control protocol was established for the sampling program; and included the routine insertion of field duplicates, laboratory pulp duplicates, blanks and certified reference standards. All samples were shipped to, and analyzed by Activation Laboratories of Ancaster, ON using its method eight - major oxide, rare earths and trace element package by fusion ICP and ICP/MS in addition to niobium by XRF, and fluorine by method 4F-F.
*Total Rare Earth Oxides (TREO) include: La2O3, Ce2O3, Pr2O3, Nd2O3, Sm2O3, Eu2O3, Gd2O3, Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, Lu2O3 and Y2O3.
Light Rare Earth Oxides (LREO) include: La2O3, Ce2O3, Pr2O3 and Nd2O3.
Middle Rare Earth Oxides (MREO) include: Sm2O3, Eu2O3 and Gd2O3.
Heavy Rare Earth Oxides (HREO) include: Tb2O3, Dy2O3, Ho2O3, Er2O3, Tm2O3, Yb2O3, Lu2O3 and Y2O3.
Middle to Heavy Rare Earth Oxides (MHREO) is the sum of MHREO and HREO.
