This NI 43-101 Technical Report outlines the mineral resources of the Duncan Lake Iron Project as of October 2012. The report details the proposed recovery methods based on test work conducted at SGS Lakefield. The project is currently in the development phase, with the finalized flowsheet intended for inclusion in a Preliminary Economical Assessment report.
The December 2011 preliminary economic assessment for VMS Ventures on the central Manitoba deposit plans to produce only copper concentrate, because of the low zinc grade, using existing sequential flotation capacity.
This technical report outlines the recovery methods for the Taviche Project, conducted by Broad Oak Associates in 1993. The assessment assumes that the mineralization present at the site is amenable to standard mineral processing techniques, specifically crushing, grinding, and flotation. Based on comparable operations in the region, the expected recovery rate for silver is estimated to be in the 80% range.

This technical report details the recovery methods and processing plant operations at the Meadowbank Mine as of February 2012. The facility utilizes a conventional gold plant flowsheet originally designed by Hatch Engineering after Agnico-Eagle acquired the project in 2007. The process includes primary and secondary crushing, grinding via a semi-autogenous mill and ball mill (SABC circuit), gravity concentration, and gold recovery using a carbon-in-pulp (CIP) circuit. The plant achieved commercial production in March 2010 and has undergone capacity upgrades, including the addition of a secondary crusher in 2011, increasing throughput to 9,840 tonnes per day.

This Feasibility Study outlines the expansion of the Choco 10 gold recovery plant operated by Rusoro. The existing facility, commissioned in 2005, currently treats saprolitic material at a throughput of 5,000 t/d. The proposed expansion aims to increase total capacity to 20,000 t/d by adding a new 15,000 t/d processing line while retaining the existing 5,000 t/d circuit. The new design focuses on treating hard rock ore with a target annual production of 500,000 oz of gold.

This NI 43-101 Technical Report outlines the Preliminary Economic Assessment (PEA) for the AZOD Zinc Oxide Project located in Cusco, Peru. The project focuses on the recovery of zinc and lead from oxide mineralization using a combined pyrometallurgical and hydrometallurgical processing route. The proposed facility includes a crushing plant, a Waelz rotary kiln for reductive roasting, and a conventional hydrometallurgical refinery for fume processing.
The September 2011 report for Pan American Silver and Orko Silver on the Durango, Mexico, property turns 137 ppm silver and 0.26 ppm gold feed into doré, using oxygen and sulphur to detoxify tailings.
This section of the technical report details the recovery methods for the Timmins Talc-Magnesite project. The process facilities are designed to treat 500,000 tonnes per year of talc-magnesite ore. The plant operates continuously with 85% availability to exceed 310 days per year. The production process involves crushing, grinding, flotation for talc recovery, and leaching for magnesium oxide production.
This NI 43-101 Technical Report details the process design for the Lac Jeannine Fe Tailings Project in Québec, Canada. The plant is designed to process 7.0 Mtpa of tailings material with a feed grade of 7.0% total Fe. The processing circuit utilizes hydraulic classifiers, high-frequency screens, jigs, and spirals to upgrade the iron content to a target concentrate grade of 65-67% Fe. The design is based on COREM testwork and similar projects in the Labrador Trough.

The 2024 Technical Report for the Clayton Valley Lithium Project outlines the recovery methods for a feasibility study focused on lithium carbonate production. The process design is optimized for a phased approach, with Project Phase 1 targeting an initial throughput of 7,500 t/d and Project Phase 2 expanding to 15,000 t/d, ultimately yielding up to 71.2 t/d of lithium carbonate. The plant design integrates a chlor-alkali facility to produce necessary reagents, specifically hydrochloric acid and sodium hydroxide, ensuring a closed-loop system for water and chemical management.
