Rosita Mining Provides Update On Stockpile And Tailings Project In Nicaragua
|Toronto, Ontario -- May 31, 2016: Rosita Mining Corporation (RST: TSX-V) ("Rosita" or the "Company") is pleased to provide an update on the Santa Rita Stockpile and Tailings Project in Nicaragua.|
DENM Engineering, ("DENM") which was awarded the engineering contract for work on the treatment plant, (see Press Release of March 21, 2016) have begun the next stage of their work program.
The draft flow sheet has been completed by DENM and each aspect of this will be examined by a testwork program that is being designed by DENM, in collaboration with SGS Lakefield.
The program will start with bench scale testwork followed by a pilot plant test; concentrating on the higher grading North stockpile which will be the focus of initial production.
Staff at the mine site have taken a new sample from this area to supplement the earlier samples. New tailings samples for testwork have also been taken.
Testwork will provide the basis for more detailed engineering by DENM. Modelling will use estimates of reagent costs delivered to site and will examine and cost local capital equipment. This data will provide input for a Preliminary Economic Assessment ("PEA") to be completed in the 4th quarter of 2016. John Cook, President and CEO, stated that "Advances in the flow sheet development have been very positive but further testwork is required for confirmation of these results."
Santa Rita Stockpile Resources
The updated NI 43-101 resources for this metallurgical program were filed with Sedar on March 21st, 2016. This incorporated the results of a reverse circulation drilling campaign completed by Rosita in the fourth quarter of 2015. This work included 1,040 m of drilling in 55 vertical in-fill holes on five stockpiles located near the former Santa Rita open pit and 87 auger holes totaling 460 metres in a portion of the tailings piles, drilled in 2012 and 2013.
Drilling to test the tailings only tested a small portion of the overall tailing piles which remain open for possible resource expansion.
