| Open Pit Mine design, planning and engineering |
Our engineers have strong operational and technical backgrounds and have gained substantial experience in mines across multiple commodities, methods, continents and countries. In addition, we are able to draw on the broader skills across our company’s global workforce. This ensures that our solutions and advice are not only practical and workable, but take account of appropriate geotechnical, hydrogeological, economic and environmental considerations.
Our services cover scoping, pre-feasibility and feasibility studies and economic evaluations, detailed mine design and layouts, production scheduling and equipment selection, operating cost estimation and capital expenditure estimation. We also have key people pro-actively reviewing improved mining methods outside traditional approaches.
Assisting us in our work are requisite skills with all major software design, optimisation and scheduling packages. We have expert users for a range of software packages including Whittle, Gemcom, Vulcan, MineSight, Datamine, Surpac, Talpac, Xpac and Minemax.
We have developed an innovative and rigorous mine planning methodology that takes a mineral resource through to a comprehensive technical report inclusive of the life-of-mine plan and techno-economic model. The methodology first focuses on pit optimisation to determine the cut-off strategy, economic mining depth, size and scale of operation. We are dedicated to identifying the best option for project development and producing client-focused solutions to technical challenges.
With the growing need to bring projects into production more quickly and on budget, we can accelerate the process for mining companies by supplying quality consultants to supplement the client’s own technical resources to achieve the desired outcomes within the project timeframe. Our personnel will ensure appropriate decisions to guide project development are made at the earliest opportunity, and are committed to reviewing what aspects of project advancement can be done in parallel to minimise the risk of any rework.

| Underground Mine design, planning and engineering |
Ensuring technical viability and economic realism
We have years of first-hand underground mining experience in most countries and across multiple commodities using all common mining methods. As a global Aditya Coal group, we have specialist underground mining expertise to provide solutions for the unique features of each project.
Based on this extensive experience, we utilise an innovative and rigorous mining method selection and planning methodology that maximises the economic benefit of the project. The methodology first focuses on understanding the complete mining context or characteristics of the deposit. This is the fundamental information required to select the appropriate mining method and establish a robust mine plan. The design of stoping blocks using the appropriate cut-off grades and minimum mining widths is followed by optimised production and development scheduling. All mine design and schedule opportunities are left open until an optimised plan is defined.
We recognise the constant need to match changing commodity prices and capital costs with appropriate responses from mining operations: reduction in operating and/or capital costs when prices fall, and increasing capacity when prices rise. We also understand the socio-economic implications of mining operations and address these in our strategic planning.
We are focused on producing mine designs and schedules that make the most effective use of mine capital, in both short and longer term time frames. We can assist companies optimise the transition from open pit to underground mining by offering a thorough analysis of the appropriate cross-over depth as well as presenting highly mechanised and often automated solutions.
Whether optimising an existing operation or deciding how to extract a new deposit, Aditya Coal can help ensure appropriate solutions are understood and implemented.

| Mining Economics and Finance |
Commodity price and macro-economic assumptions are frequently required as input to our technical authoring and reviewing mandates which include:
- Technical studies requiring input for cut-off grade determination and optimisation analysis for Mineral Resource and Ore Reserve reporting;
- benchmarking for comparative cost of production analysis;
- Financial Models (link to service statements) for comparative assessments of economic performance; and
- Mineral Asset Valuations (link to service statements) for reporting in regulatory documentation prepared for the equity capital markets.
Approach
To facilitate the above Aditya Coal has established a historical database with daily and monthly granularity covering the majority of international benchmark indicators including: commodity prices for bulk commodities, base metals, precious metals, gemstones, energy products and industrial minerals; and macro-economic parameters for country specific consumer price indices and exchange rates. In addition Aditya Coal collates on a quarterly basis various financial analysts’ quarterly, annual and long-term commodity price assumptions. These are subsequently collated in real terms to establish a median for each reporting period defined as the Consensus Market Forecasts (“CMF”). Specifically the CMF comprises annual forecasts leading to the long-term price (“LTP”) assumptions as appropriate for Ore Reserve declarations.
Our approach in this regard is to provide a simplified independent benchmark which enables objective comparisons with that associated with the specific mandate at hand. This does not seek to replace the detailed supply-demand-price analysis as normally completed by recognised market specialists and accordingly where named reliance is required (e.g. public domain documentation) Aditya Coal recommends that these market specialists be separately appointed. Our historical databases also facilitate authoring of country profile reports and comparative country production contributions to global production and ‘reserve’ status.
Experience
Aditya Coal’s experience in this area is exemplified by the numerous mandates requiring such input for public domain consumption, specifically in respect of technical reports filed in support of equity capital markets transactions. Access to our wider natural resource sector participants also enables us to compare and contrast the current market trends in key LTP assumptions as typified by those assumed to support Ore Reserve declarations.
Furthermore we have also been engaged in specific mandates with the majority of the commodity market specialists specifically in respect of assessments requiring cost curve benchmarking. Our collective appreciation of the natural resource sector coupled with appropriate specialist input, assures that forecasts are benchmarked at the outset thus ensuring early identification of any unexplained significant variance from consensus. |
| Mining Geology |
In any mining operation, understanding the geology of the orebody and waste rocks is fundamental for successful resource estimation, geotechnical engineering, mine planning and mineral processing.
Better geological interpretations at the mine scale improve grade control, mine planning and profitability. Our consultants are leaders in understanding ore-forming processes. With a unique combination of structural geology and practical mining experience, we can assist you to improve your mine development, operations and near mine exploration. Our integrated mine models give you better near mine exploration targets, optimise mapping and grade control, reduce the risk of misdirecting ore and unintentional dilution, and improve the reconciliation of your mine.
Production pressures can make it difficult to maintain geological input. We can help you by providing regular geological mapping campaigns, as well as hands-on training of your staff at your minesite to capture geological data more effectively. We can audit your current geological, sampling, assaying and reconciliation processes and ensure that they meet best practice standards.
Our approach to geology in the mine environment is based on addressing the material issues that affect the entire mining cycle from resource estimation to mine closure. Your operation benefits by ensuring that sound geological models underpin the entire mining process.

| Grade Control and Reconciliation |
Understanding grade distribution and optimising mining selectivity through grade control is essential to achieving the mine plan. Aditya Coal has the expertise to implement, monitor, analyse and react to grade control data. This allows the results to be reconciled against planned production and actual plant data. Minimising difference between planned verses actual production will improve business performance.
Approach
When analysing grade control methodology, Aditya Coal considers: the detailed geological controls on grade distribution, optimal sample spacing, sample collection, sample preparation and analysis, quality control, and optimising costs and benefits.
When undertaking reconciliation studies, Aditya Coal considers: resource models used for short and long-term mine planning, mining selectivity, dilution, losses and ore allocation records, stockpile records, plant feed records and production results.
Experience
Aditya Coal employs a number of geologists with significant operational experience. In their previous roles as mine geologists at various international operations, their duties included grade control, optimising the selective extraction of ore and routine reporting of the multiple components of reconciliation.
Our geologists possess a sound understanding of the full spectrum of mining operations, coupled with geological modelling, sample theory and their practical application.
Aditya Coal has a large skill base in the use of advanced mining software packages, such as Datamine, GEMS, Vulcan and Surpac, Leapfrog and Minex, and has a good understanding of the estimation methods suited to grade control in many different styles of deposit and different commodities.
