Quest Drilling Discovers New Deep REE Zone Northwest of the B-Zone Pegmatite Deposit, Returns Up to 14.3 Metres at 2.65% TREO, Strange Lake, Quebec
Highlights:
- B-Zone drilling continues to expand the size of the high grade mineralized surface Pegmatite Spine for over 1.2 km in strike length, with widths varying from 125 to 550 m and vertical thickness from 10.0 to over 191.0 metres
- Multiple, high grade intersections of between 1.10% and 31.47% TREO over widths of 0.75m and 67.0m characterize all holes drilled into the surface pegmatite zone, within a larger, 152.6 and 314.6 m-thick, mineralized envelope grading between 0.86%-1.06% TREO
- Deepening of 2009 drillholes into the B-Zone deposit have extended the granite hosted mineralization from a maximum vertical thickness of 135.2 m to over 314.6 m vertical
- Drilling has also identified a new, deep zone of mineralization to the northwest of the Pegmatite Zone at depths from 60.6 m to 241.0 m returning 1.11% TREO over 180.4 m including 14.3 m grading 2.65% TREO
Quest Rare Minerals Ltd. (TSX VENTURE:QRM) is pleased to report the additional results from 2010 diamond drilling of their B-Zone rare earth element (REE) deposit. Lab results for holes BZ-10-44 to BZ-10-70 and one drillhole extension (BZ09015) have returned multiple, high Total Rare Earth Oxide (TREO) grade intersections of between 1.10% and 31.47% over thicknesses of 0.75 m to 67.0 m. Heavy REE (HREE) represents between 37% and 56% of the Total REE (TREO) content intersected in the new drilling. Best intersection grades returned 1.57% TREO over 29.1 m (BZ10060), 1.43% TREO over 22.5 m (BZ10066) and 1.49% TREO over 18.8 m (BZ10048). In addition, drilling has intersected a new, deeper zone of mineralization to the northwest of the surface Pegmatite returning 2.65% TREO over 14.3 m including some very high-grade intervals returning up to 31.47% TREO over 0.75 m carrying 17.6% HREE. More drilling will be required during the winter program to better define the extent of this important new area of mineralization. The detailed drill sample analysis table has been posted to Quest's website homepage at www.questrareminerals.com for review.
"Definition drilling on the B-Zone Pegmatite continues to return very strong grades of REE over important vertical thicknesses with consistently high proportions of valuable HREE," said Peter Cashin, Quest's President & CEO. "With the evidence of a new area of mineralization to the northwest from our Pegmatite Zone, the B-Zone deposit is developing to be a larger resource than originally thought. The Pegmatite Zone will likely constitute the focus of more advanced economic assessments of the B-Zone deposit in the future with additions to the resource model coming from the new deep zone as well as extensions of the Pegmatite Zone to the north and south."
B-Zone Definition Drill Program
Assays have been received for the 27 additional definition drillholes and one 2009 hole extension, representing 6,005.4 m (see Table 1, 2). The definition drilling program was designed to probe the B-Zone at drill centers of between 50-100 m. Drill results continue to confirm strong REE mineralization over 1.1 km strike length and over widths of up to 600 m. Drilling continues to define mineralization to be relatively flat dipping. A north trending Pegmatite Zone at the core, or spine, of the mineralized envelope (see Figure 1), has been defined along a minimum strike length of 1.1 km and vertical thicknesses of up to 191.3 m and to constitutes the highest grades observed in the B-Zone deposit. The surface footprint of the deposit is expressed as a two km-long, northeast trending airborne radiometric anomaly northwest of the Strange Lake Main Deposit. The radiometric anomaly abuts to the northwest against Brisson Lake and may extend further under the lake. Historical IOC drilling, located one km further to the north, indicates that mineralization may continue in this direction.
The best results from the additional drillholes of the program (see Table 1 for hole locations) are:

The better grades of mineralization are associated with what is termed the Pegmatite Zone which is composed of a high proportion of very coarse-grained pegmatite intercalated with extremely altered intrapegmatitic Strange Lake peralkaline granite at the uppermost parts of the B-Zone mineralized system (see Diamond Drill Section in Figure 2). The highly-altered granite hosting pegmatites continue to carry elevated grades of REE in excess of 0.7% TREO over core lengths of over 314.6 m. A 0.85% TREO cut-off, as specified in Quest's recent Preliminary Resource Estimate (see Press Release: April 7, 2010), was used in determining the average grades of diamond drill intersections.
In addition to the definition drilling on the Pegmatite Zone, deep drilling to the northwest at a vertical depth topping out at 60m below surface has intersected a new zone of pegmatite-style mineralization. The new Pegmatite Deep Zone was intersected in drillhole BZ10070 to a depth of 241.0 m. Further drilling will be oriented to expand this important new area of mineralization, likely during the proposed Winter 2011 drilling program.
Revised 43-101 Resource Estimate - B-Zone Deposit
Work is continuing on building and finalizing the digital database for the 2010 diamond drilling program. Once the remaining assay data is received from the Laboratory and incorporated into the data file, it will be delivered to Wardrop Engineering, Inc. of Toronto, Ontario, for resource calculation. It is anticipated that the revised resource estimate will be delivered before the end of the First Quarter of 2011 for filing on SEDAR.com.
Quality Control
Mr. Peter Cashin, P. Geo., is the qualified person on the Strange Lake Project under National Instrument 43-101 and is responsible for this news release. Material for analysis has been obtained from drill core which was cut in half using a diamond saw. Half of the core was sent to the lab for analysis, with the remaining half left on-site for future reference. A strict QA/QC program is followed which includes the use of elemental standards, duplicates and blanks. Analyses were performed by Activation Laboratory Limited of Ancaster, Ontario.
About Quest Rare Minerals
Quest Rare Minerals Ltd. is a Canadian-based exploration company focused on the identification and discovery of new and significant Rare Earth deposit opportunities. The Corporation is publicly listed on the TSX Venture Exchange as "QRM" and is led by a highly respected management and technical team with a proven mine finding track record. Quest is currently advancing several high potential projects in Canada's premier exploration areas: the Strange Lake and Misery Lake areas of northeastern Quebec, the Kenora area of northwestern Ontario and the Plaster Rock area of northwestern New Brunswick. Quest's 2009 exploration led to the discovery of a significant new Rare Earth metal deposit, the B-Zone, on its Strange Lake property in northeastern Quebec. The Corporation recently filed a 43-101 Inferred Resource Estimate on the B-Zone deposit and has completed a Preliminary Economic Assessment (PEA) for the deposit. In addition, Quest announced the discovery of an important new area of REE mineralization on its Misery Lake project, approximately 120 km south of Strange Lake project. Quest continues to pursue high-value project opportunities throughout North America. As a result of a recently-completed marketed equity financing, Quest has a strong working capital position in excess of $51.0 million. This will be sufficient to advance the Corporations plans of completing a pre-feasibility study of the B-Zone REE deposit by 2011-2012 and to continue exploration on its other rare earth property interests.
