INTRODUCTION Mineral project development is a complex, high-risk business. Maximizing the potential of a mineral project requires ex­ tensive experience in project development and operations. If exploration, feasibility, construction, and operations are treated separately and not as part of one integrated system, sub-optimal designs can result in reduced project value. Poor choices in flowsheet design and equipment, along with less effective operational concepts at the feasibility stage, can lead to higher capital and operating costs. These issues can be avoided if the big picture is understood from the start. GreenGold offers an integrated approach to the management of mineral project development and operations. We combine operational excellence with world-class technologies that are low cost, proven, and environmentally friendly. We understand what it takes to develop, create, and sustain an operation. We’ve turned around failed businesses and transformed marginal projects into success stories. New and existing mineral operations are benefiting from GreenGold today. There is room for improvement in the mineral industry. We can do much better – so why not?

PROJECT DEVELOPMENT

08

GET IT RIGHT FROM THE START GreenGold offers a superior approach to mineral project development. Whether during exploration or feasibility stage, our Advisory Group helps create the most effective operational concepts that will ensure a fast and smooth transition into production. At the feasibility stage, GreenGold helps you formulate sound operational concepts, such as owner mining, drilling, and laboratory services. In addition, our cost-effective designs are enhanced by proven proprietary technologies and equipment. At the operational phase, our Advisory Group provides ongoing support, helping implement owner-managed ser- vices. Our end-to-end project development services are designed to provide substantial economic advantages that benefit funding efforts and project returns.

TECHNOLOGIES GreenGold designs, develops and integrates technological innovations that maximize gold, silver and cyanide recovery. Our products are economical, efficient and environmentally friendly. PROVEN TECHNOLOGICAL INNOVATION ReCYN Our world leading resin-based technology “ReCYN” reduces new cyanide purchase by up to 50% and guarantees 100% compliant tailings discharge. This technology offers substantial economic benefits to new or existing gold and silver projects. GOLD ROOM Our carbon-based flow sheets (GoldRoom) include innovative processes that increase metal recovery and reduce operating costs. All of our technologies are best integrated as part of our complete project development package at the feasibility stage. Alternatively, they can be commissioned individually at any stage of development or production.

A RESIN BASED TECHNOLOGY THAT ECONOMICALLY RECYCLES CYANIDE AND DETOXIFIES TAILINGS

13

TECHNOLOGIES

ReCYNPROCESS RECOVER CYANIDE AND DETOXIFY TAILINGS Cut cyanide purchase in half and boost environmental performance. ReCYN is the world-leading approach in cyanide recovery, gold recovery and tailings detoxification. Based on a modified resin absorbent, ReCYN reduces cyanide purchases by up to 50%, capturing free cyanide from the plant tailings and recycling it back into the leach circuit while recovering metal complexes and making them available for sale. In the process, ReCYN detoxifies the tailings stream and guarantees 100%-compliant tailings discharge. There are three versions of the ReCYN process available: ReCYN I – Cyanide recovery ReCYN II – Cyanide recovery and tailings detox ReCYN III – Cyanide recovery, gold recovery and tailings detox in one circuit. ReCYN is efficient, economical and environmentally friendly. It is the only cost-saving innovation of its kind that is generating results today on an industrial scale. All of our technologies are best integrated as part of our complete project development package at the feasibility stage. Alternatively, they can be commissioned individually at any stage of development or production.

ADVISORY GROUP

Our mission is to help guide you toward opera- tional excellence. As part of our core strategy, our Advisory Group helps you make the best possible decisions at the feasibility stage and transition efficiently and smoothly into produc- tion. Operational expertise and best practices are integrated in the feasibility study, reducing operational risks and maximizing economic performance. We provide full support in drilling, mining, grade control, processing and environmental.

SPECIALIST SERVICES

GEOMETLAB IN-HOUSE METALLURGICAL AND ASSAY LABORATORY Commercial metallurgical laboratories are rarely connected to the requirements of the design engineer. They lack the design and operational experience to understand the implications of the testwork. GreenGold offers in-house laboratory services aimed at supporting the design requirements laid out by the engineer. GreenGold metallurgists and process engineers closely follow the testwork programmes and adapt them to ongoing results. The results are always relevant to the development of the flow sheet.

21

SPECIALIST SERVICES

IN DRILL INDEPENDENT, EFFICIENT AND ECONOMICAL DRILLING The overall cost of drilling is generally underestimated when calculating the long-term running expenses of mineral projects. Operational departments, such as exploration, grade control and blasting, work as separate entities without a clear understanding of the combined cost of drilling, which is usually the major cost component. Contractors are appointed because they are perceived as having the expertise, equipment and service capacity. InDrill does not substitute the contractor but rather provides advisory services, helping you develop in-house drilling capabilities. We advise on equipment and rig maintenance. We provide ongoing operator training and organize spare parts and consumables for diamond, RC and Blast-hole rigs. GreenGold has proven that estab- lishing in-house drilling is not only more economical in the long term, reducing drilling costs by more than 50%. It also leads to more control, better efficiency and higher-quality results.

22

IN QUIP SUPERIOR EQUIPMENT AT A FRACTION OF THE COST

GreenGold designs, develops and builds specialist equipment that is used in our resin, carbon and gravity circuits. We are continually improving existing designs and developing innovations aimed at making your operation more efficient, economical and environmentally friendly. Our equipment can be purchased as part of our complete project development package or as stand- alone components. The following are some of the innovative InQuip products, designed to bring substantial benefits to new and existing plants:

SPECIALIST SERVICES

1. INCON The INCON concentrator is an innovative centrifugal device installed as an add-on to new or existing processing plants. It acts as a policeman at the back- end of the plant, retrieving un-leached precious metals in a concentrate form and stopping them from escaping into the tailings dam. An environmentally friendly gravity system, the INCON is a low-cost investment that can substantially increase metal recovery. 2. SILVER CELL The SILVER CELL is an innovative electro-winning cell designed for the treatment of gold and silver ores. Its unique features ensure high-recovery efficiency and in-situ cleaning. Designed as a single pass cell, it brings added advantages to the metal recovery circuit. 3. SCREENS Included in the InQuip portfolio are a range of screens for all CIL and resin applications. Based on cus- tomer feedback we have developed and refined the Inter-stage, transfer and safety screen designs for maximum efficiency. 4. ELUTION COLUMNS Used in both the ReCYN and carbon circuits, GreenGold has developed custom designed columns for both batch and continuous applications.
