TORONTO, ONTARIO--(Marketwire - Feb. 15, 2012) - Quest Rare Minerals Ltd. (TSX VENTURE:QRM)(NYSE Amex:QRM) -


  • Pre-feasibility work at the B-Zone REE deposit, Strange Lake area, Québec is advancing well
  • Detailed definition drilling of the B-Zone on a 50 m by 50 m grid was completed in November 2011 to the limits of the pit shell established for the deposit by Quest's most recent resource estimate (April 2011)
  • Geotechnical and metallurgical drilling over the defined deposit footprint for input into Quest's Pre-Feasibility Study was completed
  • Field data collection for use in the Environmental Baseline study (fauna, flora, weather patterns, groundwater flow and quality) was completed
  • Positive metallurgical recoveries are being achieved. Publication of final results is being slightly delayed to allow Quest to select the optimal process flow sheet.
  • Scope changes have also been made from the original Preliminary Economic Assessment to optimize and streamline the timelines for the permitting process. The completion of the Pre-Feasibility Study is now expected in the second half of 2012.

Quest Rare Minerals Ltd. is pleased to report on progress at the Corporation's B-Zone Heavy Rare Earth project, Strange Lake, Québec. Quest is advancing the project so as to be in a position to deliver its pre-feasibility study (PFS) for the B-Zone deposit in the second half of calendar 2012. Quest also reports that it is following a parallel path for the collection of the necessary data for use in the subsequent definitive feasibility study (FS). In addition, Quest recently released the results of its successful B-Zone definition diamond drilling program (see Press Release: January 12, 2012). The detailed drill sample analysis table and diamond drill sections through the B-Zone are available on Quest's website homepage at Additional details on the development activities on the B-Zone deposit were recently included in Quest's 2011 Management's Discussion & Analysis (MD&A) report filed on SEDAR on January 27, 2012.

"Our 2011 Prefeasibility work is advancing well, important changes in the scope of the project are being made when compared to how it was developed in our September 2010 Preliminary Economic Assessment," said Peter Cashin, President & CEO. "Changes include consolidating the mine and mill complex at Strange Lake, Québec, in proximity to the B-Zone to capture the power, infrastructure and heat synergies of a combined operation. This will allow for more streamlined permitting timelines related to a single footprint site. The modifications also include the construction of a 160 km access road to the Labrador coast and port facility as opposed to the originally-conceived road and slurry pipeline for delivery of crushed ore to a coastal Mill Complex. As well, in order to accelerate the completion of the metallurgical flow sheet of B-Zone ore to saleable product, Quest has engaged a second metallurgical laboratory, Process Research ORTECH Inc. of Mississauga, Ontario, to work in parallel to Hazen Research of Golden, Colorado."

B-Zone Pre-Feasibility Study Program

Pre-feasibility work on the project commenced in July 2011 and was executed by a seasoned team of engineers and technicians. The composition of the pre-feasibility study technical team is as shown below:

Discipline Responsibility
Mineral Resource Estimates Wardrop, A Tetra Tech Company
Open Pit Geotechnical Studies AMEC Earth & Environmental
Mining Design/Schedule Micon International Limited
Metallurgical Testing Hazen Research, Inc./Ortech
Metallurgical Review Micon International Limited
Process Plant Design Melis Engineering
Mine/Process Plant Facilities AECOM
Tailings/Water Management AECOM
Environmental AECOM
Off-Site Infrastructure AECOM
Financial Analysis Micon International Limited

Work has been completed to gather high-resolution topographic information for both the immediate project site located in Québec as well as along the contemplated road corridor to the Labrador coast. A trade-off study was completed to examine two possible means of access to the site. The first option is to construct an all-season road from the site to a point on the Labrador coast while the second alternative looked at construction of an all-season road from the site to Schefferville, Québec. This study identified the road to the Labrador coast as the most favourable and cost-effective option.

An update of the mineral resource estimate has been completed that incorporates all information gathered during the 2010 drilling campaign (see Press Release: April 13, 2011). The results of this updated estimate have been disclosed by means of a Technical Report that Quest filed on SEDAR on May 25, 2011.

Geotechnical information has been collected in support of preparation of an open pit mine/mill complex design (see Figure 1). Open pit mine design and optimization was completed, based on an updated grade-block model that was prepared for the 2011 mineral resource estimate update. A schedule and mine fleet selection have been completed, along with capital and operating cost estimates. The mine fleet is envisioned to utilize conventional truck-and-shovel equipment. The mine schedule was developed to provide the best grade material for an initial mine life of approximately 25 years, as the size of the estimated resource is sufficient for many more years of operation at the envisioned mine throughput rate of 4,000 tonnes per day.

Geotechnical Drill Program

A total of 23 geotechnical drillholes for 953 m were completed on the project. These holes will be used for rock stability testing, groundwater flow testing, condemnation drilling over proposed tailings and mine complex (Mill/Concentrator, surface installations) sites and for proposed airstrip sites.

Metallurgical Drill Program

A total of 30 metallurgical test holes for 3,819 m were completed across the entire surface footprint of the B-Zone deposit (see Figure 2). The material provided by this drilling will be used to undertake pilot plant tests on the metallurgical flowsheet developed for the mineralization. This will ensure that the metallurgical characteristics are such that a single process can be applied to the entire deposit. Pilot plant work is currently in the planning stages.

Recent positive metallurgical test work (December 2012) evaluating two different process routes has resulted in significant improvements in product recovery. Although early indicators support an important breakthrough, these new findings have necessitated a revision to the development program. To the extent that these results prove to be repeatable this will need to be incorporated into the design and the schedule impacts will become clearer as the details are obtained.

We expect the new test procedures to require an additional two to three months to develop. If this proves to be successful, these modifications will be incorporated into the design. We are not sure of the full impact on the downstream process but expect to be able to optimize and modify the process to best accommodate final product requirements.

2011 B-Zone Definition Drill Program

Results for 138 diamond drill holes representing 17,110.4 m (see Press Release: January 12, 2012) were recently announced. The drilling program tested the extent of B-Zone mineralization to the limits of the Whittle Pit shell established by Quest's National Instrument 43-101 Revised Resource Estimate (see Press Release : April 13, 2011), on a 50 m by 50 m drilling pattern. In addition to enlarging the peripheral limits of the deposit within the pit-shell, drilling indicates that good higher-grade Pegmatite-style mineralization continues to the southwest, past the established limit of the pit shell.

The better grades of mineralization are associated with what is termed the Pegmatite Zone, which is composed of a high proportion of pegmatite sheets that are intercalated with extremely-altered Strange Lake peralkaline granite at the uppermost parts of the B-Zone mineralized system. The highly-altered, granite-hosted zones continue to carry elevated grades of REE in excess of 0.7% Total Rare Earth Oxides (TREO) over core lengths of over 314.6 m (see Press Release: December 9, 2010). These grades exceed the economic cut-off of 0.579% TREO estimated for the deposit by Quest's revised resource estimate for the B-Zone (see Press Release: April 13, 2011). The cut-off grade was established from cost estimates determined by Quest's PEA study (September 2010). Revisions of the project scope developed by the current pre-feasibility study will likely modify these cost estimates.

Project Capital Cost Estimate

The Quest pre-feasibility team is in the process of updating project capital costs and incorporating their findings into capital expenditure models for the project. A project cost optimization process will determine where maximum cost efficiencies can be realized for the final project scope. Considerable effort is being undertaken to minimize the capital cost escalation that many projects are experiencing around the world.

Project Operating Cost Estimate

Operating costs are being updated as the metallurgical test work is refined. The potential interaction between the refining process and the metallurgical operation requires that cost iterations be determined and these costs will be refined as the process advances. As well, given that the project scope has been revised since the delivery of Quest's Preliminary Economic Assessment (PEA, see Press Release : September 9, 2010), operating cost estimates will be updated to reflect the changes. The largest scope changes to the project are:

PEA Project Scope (SEPT. 2010) Revised Project Scope (2011)
Mine Complex located at site, Port and Mill Complex on the Labrador Coast. A slurry pipeline was conceived to deliver crushed ore from mine to mill. Concentrate shipped from Port. Mine/Mill Complex on-site, delivery of product to Port and delivery of materials and supplies from Port to site. Will simplify and streamline the permitting process due to reduced environmental impact.
160 km access road from Port to site for delivery of materials and supplies. 160 km access road from Port to site for delivery of materials and supplies and product from site to Port for delivery to markets.
Separate electric power requirements for Port/Mill and Mine. Single power requirements for a combined Mine/Mill and reduced requirements for Port.
Two environmental assessments for Mine & Mill in separate provincial jurisdictions. Single Mine/Mill environmental assessment for the Province of Québec.
Process water usage across two Provincial jurisdictions. Single-jurisdiction water-use permit for Québec.
Process flowsheet developed using conceptual information Process flowsheet developed using results of detailed laboratory test work
High-level capital and operating costs developed Capital and operating costs will be developed to a level of accuracy appropriate to the study
Project development schedule reflects construction phase only Project development schedule includes time required for study completion, public consultation, permitting, financing and construction phases

"The work on revising the project scope when compared to our 2010 PEA will serve to optimize the economic potential of the B-Zone deposit over its notional production life," said Reno Pressacco, Vice President, Operations for Quest. "This revised project scope offers the advantage of using a single power supply for the entire project, removes the risks associated with a pipeline transportation system in those climate and terrain conditions, improving the management of the operation and simplifying and streamlining the permitting processes. We have been very encouraged by recent positive findings from our metallurgical test work and are confident that a final metallurgical solution for Strange Lake mineralization will be developed."

2012 Pre-Feasibility Study and Definitive Feasibility Study Work Program

In order to accelerate the delivery of both pre-feasibility and definitive feasibility (FS) studies, a parallel-path of required work programs has been established for the project in 2012.

The pre-feasibility study work program will include completion of the metallurgical solution for the B-Zone, finishing of the preliminary engineering for the project, execution of the financial analysis for the project and delivery of the final National Instrument 43-101 compliant Pre-Feasibility Study technical report. A budget of $2.5 million has been allocated for completion of this work.

The parallel-path, FS work program includes completion of an updated mineral resource estimate, pilot plant test work, mining studies, environmental baseline studies, detailed engineering (infrastructure, tailings storage), transportation studies, separation plant studies, completion of a detailed rare earth market study and stakeholder consultation activities. This program has been budgeted at $21.0 million for Quest's 2012 fiscal year.

Project Schedule Delivery Expectations

Due to the significantly expanded nature of the Strange Lake B-Zone deposit scope and delay in the delivery of the final metallurgical flow sheet, it is anticipated that the pre-feasibility study will be delivered during the second half of calendar 2012. At that time, Quest will have a more accurate idea as to the delivery timelines for its definitive feasibility study and for mine start-up.
