Aurvista Gold Corporation Announces Preliminary Metallurgical Results from the
Douay Gold Project
Montreal, Quebec : Aurvista Gold Corporation (“Aurvista” or the “ Company”) ( TSX-V: AVA, OTC QB:
ARVSF; Frankfurt: AV2) is pleased to report Preliminary M etallurgical Test results (the “Met Test Results”)
for gold recovery at the Company’s Douay Gold Project (“Douay”). Ten sample composites totaling 311
kilograms from the principal gold zones at Douay (Northwest, Douay West, Main Porphyry, 10, 20, 531 and
Main) as outlined by Duke (2012)1, were submitted for metallurgical testing at Base Metallurgical Laboratories in
Kamloops (B.C.).
The average gold grade of the sample composites was 1.89 g/t gold. Gold was the primary economic element;
other possible revenue generating metals including copper and silver were at trace levels in most of the samples.
The samples also contained on average 1.50% sulfur.
Using gravity and flotation, gold recovery to the concentrates was very consistent. The average gold gravity
recovery was 26 % with flotation recovering an additional 66 %, totaling an average 92 % recovery. The tests
indicated a strong correlation between gold recovery and sul fur recovery, indicating that gold may be associated
with the sulfide minerals.
To understand the sulfur and gold relationship, another series of test s were performed to recover a gravity and
flotation concentrate, followed by cyanidation leaching of the flotation concentrate. Leaching tests were
performed on the flotation concentrate regroun d to 2 different leach sizes: 20 µm K80 and 15 µm K80. The finer
regrind size produced the best performance. The average gold extraction for the gravity, flotation and leach
process was 85%. The performance of the two Northwest Zone composites, from a felsic volcanic host rock,
improved from the whole feed cyanide leaching (see below) , but they still lagged in compa rison to the other
composites. The average recovery of this process, excluding the Northwest Zone samples was 88.9 % in mafic
volcanic and porphyry host rocks.
Aurvista’s President and CEO, Jean Lafleur, stated: “We are very plea sed and encouraged by these preliminary
metallurgical test results, as the early indications for gold recovery are in line with the recoveries achieved
elsewhere in the Abitibi Belt at projects with comparable mineralization styles and similar or lower gold grades.
Additional drilling and further metallurgical testing is planned toward the end of 2017 , and we are confident the
recovery process will continue to improve as we advance Douay.”
Mineralogical analysis of the zones indicated the sample composites contained relatively low levels of the iron-
sulfide (pyrite), with only trace levels of other sulfide minerals. The remaining host rock was comprised of mainly
feldspars (potassium-aluminum silicates) , quartz (silicon oxide) and carbonate (iron-calcium rich carbonates)
minerals.
A Bond Ball Mill Work Index (the “Work Index”) determination was performed on a combined composite sample

of all the zones and the indicated mineralization is considered relatively hard. The Work Index value was
determined to be 18.5 kWh/tonne. In addition to gravity concentration and flotation tests initial testing also
examined whole feed cyanidation as a possible process to extract gold. The tests were all conducted at a nominal
75µm K80 primary grind size over 2, 6, 24 and 48 hour leach times. Most of the samples displayed relatively fast
cyanide leach times reaching a plateau at about 6 hours . The whole feed cyanide leaching response was highly
variable: four sample composites achieved greater than 90 % extraction. However, the average performance
extraction was 81 %, with two samples from the N orthwest Zone having only 52 % extraction. Cyanide and lime
consumption was low, averaging 0.3 kg/t and 1.4 kg/t, respectively.
The gravity-flotation-leach process (“GFL”) should result in capital and operating cost advantages over whole ore
leach. Flotation process equipment would be required, but the subsequent leach cir cuit would be approximately
one-tenth the size of the whole ore leach process. The cyanide and li me consumption of the GFL process is
estimated at only 0.2 kg/t and 0.4 kg/t of the feed. The initial testing produced posi tive metallurgical response,
with further metallurgical testing warranted to optimize metallurgical response and lower the cost of the process.
