VANCOUVER, July 31, 2017 /CNW/ - Stina Resources Ltd. (CSE: SQA) (OTCMKTS: STNUF)  (the "Company" or "Stina") today announced a new metallurgical testing program on vanadium samples taken from its Bisoni McKay property in Nevada.

Hazen Research Inc. of Boulder Colorado (Hazen) has been contracted to conduct the new tests. Hazen Research has conducted numerous metallurgical tests on Bisoni McKay samples dating back to 2005.

In 2010, Hazen conducted experiments using magnetic separation methods, direct leaching of oxidized material, acid pugging and curing, and roasting of carbonaceous and transition materials followed by leaching.

In the 2010 study, Hazen reported the recovery of vanadium in the oxidized material was proven successful.

Further experiments are necessary to optimize recovery in the primary (carbonaceous) and transition zones, which host the highest vanadium grades at Bisoni McKay. Among the variables that require further experimentation are acid and water dose, grind size, roasting and leaching residence times and investigation of a single-stage leach with acid instead of two leaching stages. The objective is to obtain the highest vanadium recovery using the most cost-effective metallurgical process.

Stina Resources recently recontacted Hazen to follow up on the recommendations proposed in their 2010 report. Hazen responded with a proposal to conduct a number of additional tests to optimize vanadium recovery in view of recent technological advancements. Among them was an investigation of recovery of vanadium contained in goethite using magnetic separation methods. This approach could  serve as a pre-concentration ahead of  single-stage roasting for the primary and transition material. Additional testing includes roasting followed by leaching and experimentation with acid autoclave leaching. The proposal contemplates four autoclave experiments—two using varied temperature and two using varied levels of acid concentrations.

Stina Resources is shipping a representative sample of carbonacous material to Hazen Research's facility in Golden, Colorado. The metallurgical test and report is expected to be completed within 12 weeks after receipt of the sample.

On behalf of the Company, Tony Hammond, Director and QP, will oversee the test at Hazen Research and will provides updates on the progress of the research.

On behalf of the Board of Directors,

"Brian Stecyk"            

President/CEO Director
