ASX-listed Mustang Resources says in its latest quarterly report (for the period ended 30 September 2016) that the bulk sampling plant at its Montepuez ruby project was fully commissioned during the quarter, in the process recovering approximately 460 carats of high quality rubies.

The project is located within the Montepuez Complex in the Cabo Delgado Province of Northern Mozambique. Mustang's licences lie along the established NW-SE ruby mineralisation trend which also transects licences of AIM-listed Gemfields.

The two 16 ft rotary pans of the plant processed 2 683 tonnes during the commissioning phase up to 24 October 2016. Mustang says it should be noted that the sample processed to date is not yet representative of the entire deposit and that current grade estimations are therefore only indicative of the overall deposit’s grade.

It adds that further mining optimisation is ongoing (thereby increasing the grade) given the high percentage dilutive sand and gangue material that was fed to the plant during this initial commissioning phase.

Work is continuing to process the maximum volume of gravel from the Alpha deposit stockpile by end of Q4 2016 with the plant ramping up to process up to 350 m3 per day (approximately 525 tonnes per day at specific gravity (SG) of 1,5).

The Alpha deposit, discovered through initial reconnaissance sampling in July 2016, is the current focus of bulk sample mining operations with 8 385 m3 (approximately 12 997 tonnes) of gravels already mined and transported to the plant for stockpiling. The first phase of the pit has reached bedrock at 9,2 m with an average gravel package of 1,8 m. The pit is currently being extended to the south-west.

The company is currently planning a full auger drilling campaign, starting from the Alpha deposit extending outwards. The purpose of this drilling campaign will be to map the extension of the Alpha deposit and thereafter to also map all the gravel beds within all three of the Mustang concession boundaries.
