MONTREAL, QUEBEC--(Marketwired - Aug. 29, 2016) - Aurvista Gold Corporation
("Aurvista" or the "Company") (TSX VENTURE:AVA)(OTC PINK:ARVSF)(FRANKFURT:AV2) announces
the completion of an Airborne Magnetic-Time Domain Electromagnetic-Radiometric Geophysical Survey (the "Survey") (refer to
the Company news release dated June 14, 2016) and the release of Survey's result, in addition to an update of the Company's
on-going Detailed Targeting Program at its 100% owned Douay Gold Project ("Douay") with drilling planned for Q4-2016 and
Q1-2017.
Geophysics focused on Douay's central and western portions and was primarily designed to define key contacts and faults which
could be linked to the gold mineralization, their extensions and outline potential gold-bearing massive sulphides within 2 km of
the porphyry unit, all to a depth of -150 meters, within the 10 km long by 3 km wide Douay-Style Mineralization ("DSM") corridor.
Previous geophysical programs identified a number of EM-INPUT™ anomalies that are consistent with massive sulphide development as
discovered elsewhere in Quebec-Ontario segments of the Abitibi Belt.
2014-2015 Geophysical Compilation and Interpretation
In 2014, Aurvista completed a Geophysical Interpretation (the "GI") of the 1976 government electromagnetic-magnetic ("EM")
INPUT™ survey, the 11 ground Induced Polarization ("IP") surveys completed from 1986 to 2011, and the Company's 2011 airborne
magnetic and the 2 ground IP surveys from 2015 (refer to previous Company news releases dated December 17, 2014, and April 8
and April 30, 2015). The GI assisted in identifying additional targets with similar geophysical signatures to those
associated with already known gold mineralization on Douay.
The interpretation confirmed the DSM corridor comprising of a SE-tilted parallelogram-shaped block, bounded in all directions
by SE-NW and NE-SW splay faults of the E-W trending Casa Berardi Deformation Zone (the "CBDZ"). The DSM consists of a unique
geophysical response of chaotic, non-linear, and distorted bands of strong magnetic highs and complementary lows resulting from
the faulting, shearing, and alteration of the host rocks. The 8 known higher and 2 lower grade gold zones within the DSM occupy
magnetic lows and are surrounded by strongly magnetic basalts and gabbros. The GI also showed potential outside the DSM for
additional significant and untested gold and base metal mineralization along the 20 km trend of Douay. EM INPUT™ clusters of
conductors were identified and require further testing to confirm potential massive sulphides based on the geological-geophysical
association.
IP can help identify disseminated sulphides and faults potentially linked to the gold and/or VMS mineralization. The IP at
Douay showed a complex array of crisscrossing E-W, NW-SE and NE-SW faults mirroring structures outlined by the airborne magnetic
survey. The array forms anastomosing patterns, and as in the case of the heavily tested Douay West Zone, the gold mineralization
appears to sit at the junction of anastomosing faults. Where narrower linear IP resistivity lows occur they are overlapped by
similar linear EM-INPUT™ anomalies, and correspond to conductive linear and recessive graphitic faults typical of the CBDZ.
Discrete groupings of EM INPUT™ anomalies located in felsic and mafic volcanic rocks are associated with areas of higher IP
resistivity, likely a non-graphite component to the conductors, such as sulphide-bearing cherts, as observed within the 6 km by 1
km EM INPUT™ grouping running westwards from the South Porphyry.
2016 Geophysical Survey and Interpretation
Aurvista contracted Prospectair Geosurveys of Gatineau (Quebec) to complete and airborne helicopter magnetic,
time-domain electromagnetic ("TDEM") and radiometric survey to complement the 1976 EM-INPUT™ and 2011 magnetic survey but at
greater depth. A total of 1,421 line-km were flown along N-S 150 m spaced lines with the magnetic responses mimicking those from
the Aurvista 2011 magnetic survey. The Total Counts per Second ("CPS") of the radiometric portion of the Survey maps out 3 areas
of shallow overburden (higher CPS) with felsic rocks either "granites", porphyries, cherts and/or rhyolites-rhyodacites ("1" to
"3"), 8 linear troughs (lower CPS) linked to possible faults ("4" to "11"), and the N-S esker (higher CPS) ("12") under the
Amos-Matagami provincial highway (higher CPS).
The TDEM survey outlined 7 strong anomalies ("A" to "G"), all associated to the strongest EM-INPUT™ anomalies, 4 in proximity
to the CBDZ ("A" to "D"), NW of the DSM, and 3 in proximity to, and surrounding the 'South Porphyry" ("E" to "G"), S of the DSM
(refer to Figure 1 using the following

To summarize, Anomaly "E" is the most significant, located in proximity to the gold bearing "Main Porphyry", the "South
Porphyry" and the "Adam-Porphyry". There are chlorite-sulphide bearing "feeder pipes" nearby as observed in drill holes DO-92-24
(refer to Figure 2 using the following link)
and DO-11-34, typically found in association with massive sulphide mineralization, yet to be found at Douay. The historical drill
holes DY-99-04, 05 and 06, 46878-0, 46899-9 and 0, 64487-0, 468880-0 and D-92-32 skimmed the anomaly by drilling above or holes
were too short, but explained the conductive source as graphite. There is no graphite in the re-logged drill core.
Aurvista is committed to the continued exploration of Douay
The Company is well advanced in its previously announced 2016 two-staged exploration campaign on Douay with the primary
objective of defining drill targets to increase known Mineral Resource estimates*.
The First Stage of the campaign, slated for completion in Q4-2016, will tackle Priority Targeting (the "Program") in
two areas, the DSM and 6km by 1 km EM-INPUT™ sector, where management is confident additional gold mineralization will be
discovered. The Second Stage will consist of 4,000 metres of drilling to delineate additional gold mineralization.
The Aurvista exploration team is now focused on core re-logging of previous and historic drill holes along 26 sections across
Douay, including all previously known gold mineralized and non-mineralized segments, with the purpose of defining the chemical
signatures and alteration mineralogy of the known gold mineralization. The purpose of this work is to confirm the suspected
source of the volcanic intrusion. This work integrated with the geophysics will assist in vectoring the drills towards additional
gold mineralization and the drilling of the best priority targets that could potentially lead to a better quality and expanded
mineral resource. To date, drill core re-logging of 45,000 meters of the nearly 200,000 meters of drill core of site stored from
all previous vendors is presenting a much simpler geological picture than previously interpreted.
There are two distinct but overlapping geological signatures: a primary Volcanogenic Massive Sulphide ("VMS") of Copper-Zinc
affinities overprinted by a secondary structurally hosted gold system. The interpreted geological signature is very similar
to the 15+ million ounce Doyon-Bousquet-Laronde Mining Camp located 100 km S-SW of Douay, along the Cadillac Larder Lake
Deformation Zone.
Douay now consists of a northern corridor of fairly pristine, well preserved volcanic tuffs of felsic to intermediate
compositions; the central 3 km wide DSM corridor hosting the CBDZ with a mix of porphyries, basalts, felsic volcanic rocks and
iron formations, and gold-hosted shear zones; and a southern corridor of mostly basalts with siliceous-chemical sediments and
chlorite-sulphide bearing feeder-pipes, both typical of VMS systems.
There are well defined continuity of geological units and structures across Douay as was suggested by the previous 2014-2015
geophysical interpretation which has now been confirmed as the iron rich host of the "Douay West" Zone, west of the "South
Porphyry", was also observed E-SE of the same porphyry for a distance of 4+ km. The E-W fault or shear zone hosting "Douay West"
is the same structure hosting the "Adam-Porphyry".
The volcanic stratigraphy trends in a NW-W to E-SE directions whereas the gold structures trend E-W. There are at least a
dozen of these subparallel structures. The previously held interpretation of 8 independent higher grade gold zones is incorrect.
Management believes there are additional higher grade zones and are linked by an extensive network of E-W, NW-SE and NE-SW
structures in magnetic iron rich volcanic rocks, but now non-magnetic sulphide bearing, hosting iron-carbonates alteration,
porphyries and/or silica-rich alteration and/or sodium-rich alteration.
