Our team consisted of local experienced & professional engineers and geologist and several expatriates (associate) with proven performance to advice and assist Mining and Industry in Indonesia. We provide consultancy & engineering services both for Mining Industry and Civil & Infrastructure Development. Quantus provides services for Exploration & Geological Engineering (Exploration Management, Geological Modeling, and Resources Estimation (following JORC & KCMI Standard)), Mining Engineering (Reserving, Mine Planning & Scheduling), Geotechnical Investigation, Hydrology & Hydrogeology Study, Environmental Planning & Monitoring (Incl EIA/AMDAL), Civil & Infrastructure Engineering & Design, Mine Closure & Reclamation, Due Diligence & Technical Review, Feasibility Study & Viability, and Full Technical Services (Mining).

Vision Our vision of being the 'local leader of integrated mining services & operations' means providing integrated services from initial exploration stages, mining engineering, technical support engineering, to mining operations. We believe by applying good mining practices and involving local communities in developing mining project, it can lead to sustainability and creating values to stakeholders. 'Better mining practices leads to better mining values to Indonesia and contribute for better Indonesia'.

Client Segmentation Our targeted clients are natural-based resource industries especially mining companies. The target markets are specified as follows;

Mining Companies Mining business in Indonesia growing rapidly in recent years and predicted will grow for another couples years especially on energy-based resources (Coal, CBM, Geothermal, etc). Currently there are more than 3.000 mining companies (IUP/CCoW) that has been stated 'clean & clear' in Indonesia. In line with growth of mining business, the demands of its manpower also growing and caused 'lack' of mining expertise. Our most target are coal mining companies both green-field project and operated-mining project. We will cooperate with mining clients; - Only working with clients that legally 'clean & clear'. - Only working with clients that financially capable. - Only working with clients that commit to implement 'good mining practices'. Commodity Traders Our services also required by commodity trading companies to secure their business especially in a cash-basis trading scheme (or advance payment system). We could provide services from resources & reserves evaluation to production monitoring.

Strategy Our strategy of delivering high quality - integrated mining services & operations has enabled us to continue to deliver value to client and stakeholders. Our teams focus on its expertise and integrate each stage of mining development. We provide both consultancy services (exploration & geological engineering, mining engineering, technical support engineering, environmental, etc) and physical works (drilling, surveying, construction, mining contractor, etc). By executing each stage of mining development, it enables us to identify risks and creates more values especially for client.

Another Natural-Based Resource Industries In line with our motto 'partner on earth engineering', we also serve clients that related with ground or earth engineering such as; civil & infrastructure projects, oil & gas industries, plantation, etc. Financial Institution & Investor Our capability, expertise, and reliability in delivering consultancy & engineering services to mining business and experiences among our employee that had working with banking industry are really required to evaluate, calculate, review, and execute mining project that financed by Financial Institution & Investor.

Services MINE CLOSURE & RECLAMATION

PRODUCTION MONITORING

LEGAL REVIEW (MINING)

Assisting client in mine closure and reclamation both in planning and execution or monitoring. As dictated on regulation, all mining activities should be 'designed for closure'. Mine closure & reclamation plan describes what the pre-mining environmental conditions and land use are, what the proposed mining and reclamation will be, how the mine will meet the regulation, and how the land will be used after reclamation is complete. Mine closure & reclamation is one of the biggest concerns of regulator that should be followed by mine owner. Our services comprise; 1. Mine Closure Planning including conceptual mine closure 2.
