Plymouth Minerals commences Morille metallurgical testwork

THE DRILL SERGEANT: Plymouth Minerals (ASX: PLH) has wasted no time in getting to work at the company’s Morille tungsten-tin project in Spain.

Plymouth has commenced metallurgical testwork on a bulk sample of Run of Mine (ROM) mineralisation from the project.

The company has selected approximately 20 tonnes of mineralised material previously mined from the Alegria mine, the largest historical mine within the Morille project area, which will now be transported to Perth, where it will undergo process testwork.

From the 20 tonnes of material 18t was crushed using a secondary crusher prior to shipment and 2t was left uncrushed.

The test work will be conducted to confirm the optimum operating conditions for each stage of the process,” Plymouth Minerals said in its ASX announcement.

“This will include a comminuition circuit to achieve the particle size required for downstream processing.”

The company explained the process will also investigate a range of traditional gravity concentration techniques including:

Dense media separation, spiral classifiers, cyclones and circular jigs; and

Froth flotation cells, magnetic separation and dewatering testwork will be also completed to enable the design of the most efficient cost effective process available.

“This is advanced stage work given the recent acquisition of the project and shows the benefits of a brownfields project,” Plymouth said.

The company indicated it also plans to take additional samples for tin process testwork from an upcoming diamond drilling program it has scheduled to commence for Q2 2014.
