INTRODUCTION Mineral project development is a complex, high-risk business. Maximizing the potential of a mineral project requires extensive experience in engineering 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. Green Gold 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 Green Gold today. There is room for improvement in the mineral industry. We can do much better – so why not?

GET IT RIGHT FROM THE START Green Gold offers a superior approach to mineral project development. At the feasibility stage, our Advisory Group helps create the most effective operational concepts that will ensure a fast and smooth transition into production. We provide complete engineering support and help implement best practices in mining, grade control, processing, ERP, accounting, IT, legal and marketing. We can guide you every step of the way or come in at key stages. Our mission is to bring operational excellence to your new or existing mineral project. The feasibility study is considered the key stage in project development requiring the highest quality inputs.and setting the tone for the entire operation. Green Gold provides all the necessary in-house expertise to make the best possible project assessment, supervising testwork, optimizing process flowsheets and working with you to create a profitable, sustainable mineral operation. At the feasibility stage, our Advisory Group helps you formulate sound operational concepts, such as owner-managed mining, drilling, and laboratory services. At the operational phase, our Advisory Group provides ongoing support, helping implement all owner-managed services. In addition, our cost-effective designs are enhanced by proven proprietary technologies and equipment. Our end-to-end project development services are designed to provide substantial economic advantages that benefit funding efforts and project returns. Project development with Green Gold accelerates feasibility studies, eases the transition into production, and equips your company with a better chance at ongoing success.

PROVEN TECHNOLOGICAL INNOVATION Green Gold designs, develops and integrates technological innovations that maximize gold, silver and cyanide recovery. Our products are economical, efďŹ cient and environmentally friendly. Our resin-based technology (RECYN) reduces new cyanide purchase by 50% and guarantees 100%-compliant clean water discharge. Our carbon-based ow sheets (GOLD ROOM) include innovative processes that increase metal recovery and reduce operating costs. Our non-chemical system (NCS) retrieves gold and silver that is otherwise lost in the tailings dam. All of our technologies are complementary and integrate seamlessly into new and existing mineral projects. They 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

RECYN PROCESS RECOVER CYANIDE AND DETOXIFY TAILINGS Cut cyanide purchase in half and boost environmental performance. RECYN is the world-leading approach in cyanide recovery, metal recovery and tailings detoxification. Based on a modified resin absorbent, RECYN reduces cyanide purchases by 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 clean water discharge. 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.

The GOLD ROOM connects seamlessly with our innovative RECYN technology.

NON CHEMICAL SYSTEM (NCS) RECOVER MORE GOLD AND SILVER WITH NON-CHEMICAL PROCESSING Maximize gold and silver recovery by retrieving it before it escapes into the tailings dam. Our Non-Chemical System (NCS) offers enhanced, back-end metal recovery using specialized sizing and gravity equipment designed and built by Green Gold. It is a natural extension to RECYN that can also be applied to mineral sands and alluvial projects.

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. Green Gold offers in-house laboratory services aimed at supporting the design requirements laid out by the engineer. Green Gold 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 ow sheet.

INDRILL 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. Green Gold has proven that establishing in-house drilling is not only more economic in the long term, reducing drilling costs by more than 50%. It also leads to more control, better efďŹ ciency and higher-quality results.

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 customer 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, Green Gold has developed custom designed columns for both batch and continuous applications.
