Newlox Gold Ventures Corp. (“Newlox” or the “Company”) (CNSX:LUX.CN) (Frankfurt/Stuttgart:NGO) (OTC:NWLXF) is pleased to provide an interim update on Stage 2 research and development of the environmentally friendly Organic Aqua Regia (OAR) gold leaching technology. This latest round of testing was based on strong results achieved for Stage 1 while further assessing the effects of temperature and time on the gold recovery process. The Newlox R&D team achieved very encouraging gold recoveries up to 98.77% during these most recent tests.
The Company is investigating the use of Organic Aqua Regia (OAR) technology as a non-toxic and water-free alternative to cyanidation for the recovery of gold, silver, and other precious metals. The multiple outstanding advantages of OAR include that it is non-toxic, is recyclable, extracts gold faster than cyanide, does not use water, and requires neither carbon nor electrowinning.
The first stage testing established that 94.68% gold dissolution is possible at ambient temperature, with nearly 100% recovery possible at 80 degrees Celsius. Stage 2 included analyses at various temperatures and diverse reaction times. This testing is essential for future economic calculations, which will weigh the reaction speed and overall efficiency against the cost of heating, to determine whether commercial units should operate at ambient temperature or with supplemental heating.
Additionally, because Newlox Gold’s current operations are in Central America, the Company may benefit from the effects of natural higher ambient temperatures than were experienced in the laboratory in British Columbia, Canada.
Testing samples of artisanal tailings feedstock, collected at the Newlox Gold artisanal tailings remediation and precious metals recovery project in Costa Rica, indicated that approximately 95% gold dissolution is possible in 8 hours at ambient Costa Rica temperatures. These results were a significant improvement over Stage 1 testing when similar recoveries were achieved with a 24-hour reaction time.

Recent tests reinforce data from Stage 1 showing that, while increased temperature does expedite reaction speed and overall recovery, levels of over 90% recovery can be achieved at ambient temperature. Heating is thus likely not necessary in a commercial setting.

Stage 2 testing is also investigating the total amount of gold that can be held in solution by a given volume of OAR reagent. This is important since the volume of reagent needed to treat each tonne of feedstock will impact the scale and cost of future processing plants. This testing phase is currently underway using concentrated samples of feedstock collected from the first Newlox Gold project in Central America.
A Message from Ryan Jackson, President & CEO:
“We are delighted with the results from Stage 2 OAR testing by our Newlox R&D team. These results build on the extraordinarily positive findings of Stage 1. We look forward to furthering success as we continue testing this spring. With continued good results from the lab, we anticipate the commencement of in-field OAR testing this summer.
OAR leaching promises to become a paradigm-shifting technology applicable not only to the US$180 billion formal global gold mining industry but also as a method to bring the US$27 billion informal gold mining industry into the 21st century.”
