This technical report presents a mineral resource update for the Matoush uranium project in central Québec, Canada, as of February 15, 2012.
Report context
This NI 43-101 technical report, dated February 15, 2012, was prepared for Strateco Resources Inc. by Roscoe Postle Associates Inc. The report documents a mineral resource update for the Matoush Project, located in central Québec, Canada. The document includes sections on mineral processing and metallurgical testing, mineral resource estimation, mineral reserve estimation, mining methods, and recovery methods.
Processing route
Mineral Processing and Metallurgical Testing
Section 13 of the report covers mineral processing and metallurgical testing. The report indicates that testwork was conducted to support the development of a processing flowsheet for the Matoush Project. The metallurgical testing program was designed to evaluate the amenability of the Matoush mineralization to conventional uranium extraction methods.
Recovery Methods
Section 17 addresses recovery methods for the proposed processing plant. The report presents a designed processing route based on the results of metallurgical testwork and historical operating data from comparable operations. The proposed design incorporates standard unit operations for uranium ore processing, including crushing, grinding, leaching, solid-liquid separation, and uranium recovery through ion exchange or solvent extraction.
Mining Methods
Section 16 describes mining operations and geomechanics. The mining method proposed for the Matoush Project is based on underground mining techniques. The report includes details on mining operations and ground support requirements, informed by geomechanical assessments of the deposit.

Technical qualifications
The mineral resource estimate presented in this report is based on a resource database, geological interpretation and 3D solids, U₃O₈ statistics, cutting of high-grade values, compositing, density measurements, variography and kriging parameters, and block model set-up. The resource classification follows NI 43-101 guidelines. The mineral resource estimate is subject to the qualifications and limitations described in the full technical report. Mineral reserves are not reported in the available sections of this document. The recovery methods section references a proposed processing flowsheet but detailed flowsheet specifications are not provided in the extracted text. Performance data, economics, ownership details, and current project status are not included in the available report sections.
