OUR APPROACH

 

We devise practical cost effective solutions for clients based on our comprehensive experience as consultants, practitioners and managers of extractive industry.

 

Modern quarrying presents a unique set of economic, environmental and social challenges for the quarrying company, the construction materials industry, local and state government and the local and wider communities.

 

Every quarry site is different, but there are common factors that determine the availability of geological resources, environmental and social impacts of development, commercial viability and sustainability.

 

ECOROC has developed a simple and practical triple-bottom line risk assessment tool and due dilgence framework to evaluate extractive resources and quarries. 

 

Adapted from the Australasian minerals industry's "JORC" 2012 Code for reporting of mineral resources and mineral reserves, we systematically apply our EROC (Extractive Resources Opportunities and Constraints) framework to our client's project needs. 

 

Our EROC framework is used to identify risks and opportunities, establish priorities, overcome constraints and address residual risks, for the project under evaluation.

 

Figure 1 below shows the general relationship between an extractive ‘resource’ and an extractive ‘reserve’.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Figure 1: Relationship Between an 'Extractive' Resource and an 'Extractive' Reserve

 

An extractive 'resource' may be viable to quarry, or it may not. The key influences are the resource characteristics (geology and source rock properties) and the 'modifying factors' (refer Figure 1). 

 

The modifying factors comprise regulatory, legal, economic, market, extraction, processing, transport, environmental, social / cultural and governmental factors or issues. These factors can and do change with time as a quarry's internal and/or external conditions change. For convenience we include resource characteristics/ geology in our list of EROC factors.

 

Figure 2 shows these factors of the EROC framework as a spectrum, focussed through a prism (which reflects the project requirements - ie a quarry development application, commercial performance assessment, resource assessment or valuation etc).

 

Conceptually the goal is to optimise a quarry's commercial and sustainability performance by identifying and addressing the risks and opportunities identified from the review of the modifying factors.

 

An optimised solution takes all the relevant triple-bottom line issues that impact on the extractive resource or quarry into account and builds in mitigation and remedial measures to provide a balanced, focussed  and optimised quarry performance. Note that safety of workers and the community is an integral component within each of the EROC factors.

Since our inception in 2000, we have successfully developed and applied our EROC risk assessment framework and underlying due dilgence index to over 150 quarry-related projects in Australia and Asia.
