MacPhersons Resources (MRP) is set to begin trial mining at the Boorara gold deposit in Kalgoorlie, Australia.

The trial mining operation is aimed at enabling accurate resource, mining and milling reconciliations to be undertaken on the deposit, which is part of the current feasibility study.

Following trial mining, MRP will be able to advance the Boorara gold deposit into full-scale production.

The company already completed reverse circulation grade control drilling on close spaced 4m x 4m pattern over the majority of proposed trial pit design. 

"Around 20,000t of ore grading 1.8g/t gold and up to 10,000t of low-grade ore grading 0.6g/t gold are expected to be extracted."

Based on drilling to date, around 20,000t of ore grading 1.8g/t gold and up to 10,000t of low-grade ore grading 0.6g/t gold are expected to be extracted from within the trial pit design.

MRP submitted the project management plan (PMP) to the DMP early last month and is awaiting approval.

The PMP consists of details of the mining method, trucking route, waste dump and office location, as well as outlining the required MRP safety management system.

Furthermore, it will serve as the final regulatory approval that is needed prior to starting mining.

MRP has engaged mining contractor MLG Oz to undertake trial mining through using a mining fleet comprising a 90t excavator, three 40t articulated trucks, bulldozer, grader and water cart.

Mining of the trial open-pit is expected to take four weeks for completion and the ore will be transported to the FMR Investments Greenfields CIP toll treatment milling facility.

The trial pit is located within the Southern Stockwork heap leach pit design at Boorara. It is centred on the dolerite host rock with the gold ore zone outcropping at surface.
