Resource and Reserve Estimations—Aggregates

Resource & Reserve Estimations Services

Our resource and reserve estimation services utilise advanced mining software to model the deposit to reflect anticipated extraction activities. This presents the opportunity to examine the impacts of quarrying technique assumptions and make informed decisions about the most effective methodology to maximise recovery of the deposit.

Deliverables

Accurate, validated resource and reserve estimates consistent with the data available and assessed with respects to confidence and operational risk.

Methodology

Our geologists and engineers employ Vulcan and Surpac to carry out resource and reserve estimates. Methods used include:

	Reconciliations between block model, quarry production and weighing systems.
	Statistical analysis of drill holes and sample data.
	Creation of geological models.
	Creation of numerical models for resource assessment and reserve reporting.
	Recommendations targeting improvements to geological data gathering and minimising resource risk.
