Midland Research Center LLC is a minerals testing, research and development laboratory with roots dating from the last century. Located in Minnesota on the Mesabi Iron Range, our personnel have a strong record of providing testing, research, and development services including

￿Testing and analysis to assist new projects advance from concept to commerciality

￿Development and testing services that assist new and existing mineral producers improve their flowsheets and processes

￿Sample processing, analysis and testing services that supplement or provide quality control for operating mineral producers

￿Research and development of new techniques

Midland Research Center has bench and laboratory-scale mineral processing equipment. Experienced personnel and a record of successful accomplishments extend throughout the North American and global minerals industry. Building on experience with major and developing mining companies and across many minerals, MRC is an independent facility that provides testing and research services to exploration, development, and operating companies locally and worldwide.

Midland Research Center LLC personnel have substantial experience in testing and process development in iron ore, other metallic minerals, and industrial minerals. MRC handles small and large projects, from short term projects or single samples to long term and extensive projects. The laboratory's equipment and personnel perform most tasks related to exploration drill core processing, bench and laboratory scale testing, sample blending, development of quality control samples, testing and development of new techniques, and other assignments that are part of the client's programs. A partial listing of capabilities and services provided by Midland Research Center is provided in this brochure. If there is a need that involves minerals but is not listed, please contact us - we may already have experience or can develop an approach with you. Midland Research Center LLC strives to deliver prompt, high quality service to clients by utilizing its facility, equipment, and skilled, experienced personnel.

Mineral Processing and Testing Capabilities

Midland Research Center's facility can handle projects of various sizes. This includes testing of small single samples and extends upward to much larger mineral processing services that can include crushing, grinding, screening/classification, flotation, balling, settling or elutriation, and other sample or process testing desired by the client.

Midland is equipped to provide specialized testing using in-house equipment, and is also able to perform sample preparation and support specialized testwork that may be performed by others. It can accommodate temporary storage of incoming materials for testing, such as drill core, mine, plant, or other larger samples, as well as test products such as assay sample pulps, pilot plant test products, and operational quality control samples. Being located in a major mining area, transportation and other infrastructure facilitates are available to provide good service to the client.

Fellow, Society of Economic Geologists, and others

￿Certified to perform NI 43-101 studies and perform SEC-quality reports.

Midland Research Center LLC has well-established industry-standard procedures for most iron ore and other minerals work. In situations where client preferences, or the nature of testing, requires modification of existing procedures or development of new procedures, Midland has the capability and flexibility to do so where it is technically justifiable. Quality control procedures and practices generally adhere to normal industry practices, although procedures and practices may also be tailored to client preferences or project-specific procedures where needed or requested due to unique or unusual nature of a specific research project, while not comprising the integrity of results and conclusions.

Midland Research Center's personnel have been involved as a significant element in many projects as the projects advance toward commercial operations or seek to improve performance. Governmental units needing or desiring minerals-related laboratory services may also have test work done at Midland Research Center LLC. In most cases, confidentiality requirements restrict Midland Research Center from providing

information about specific clients or projects without permission from the project proponent. Confidentiality of client data is a high priority at Midland Research Center.

Midland Research Center LLC is flexible; projects can be structured to best suit and match the needs and objectives of the client with Midland's capabilities. Midland Research Center may at times have the major role in testing or development work for a project. At other times, such as when an engineering or consulting firm, mining industry service provider, or other firm has a lead project role, collaboration with the other firms can be arranged as part of the total project structure. While many projects use the experience and capabilities already at Midland, if a specific item of non-Midland equipment is needed, arrangements for third party equipment can be made for integration into the Midland Research Center laboratory equipment and testing configuration.
