This report details the mineral processing and metallurgical testing program for the Goondicum ilmenite deposit in southeast Queensland, Australia, as of February 2014.
Report context
This technical report was prepared for Melior Resources with an effective date of 25 February 2014. The report documents the mineral processing and metallurgical testing undertaken for the Goondicum ilmenite deposit, located in southeast Queensland, Australia. The report includes historical operating data and proposed process design parameters based on testwork.
Processing route
Resource estimation basis
The resource estimation for the Goondicum deposit was undertaken by H&S Consultants Pty Ltd. The estimation used composite data with zone and domain characterisation applied. Univariate and bivariate statistics were generated for the mineralised zones, and spatial analysis was completed. A block model was constructed with defined dimensions. The model was flattened prior to estimation. Search criteria and domaining parameters were established for the estimation process.
Density modelling and classification
A density model was developed for the deposit. Resource classification was applied to the estimation results. The block model underwent validation through block grade visualisation, composite-to-block grade comparison, and summary statistics comparison between block grades and composites. Reconciliation was performed between estimated grades and production data.
Soil sampling and exploration target
A soil sampling program (designated SL sampling) was conducted across the deposit area. An exploration target was defined based on the soil sampling results and geological interpretation.
Impacts on resource estimates
The report identified factors that could impact on resource estimates, though specific details of these impacts are not provided in the available text.
