Montreal, Quebec--(Newsfile Corp. - December 17, 2014) - Aurvista Gold
Corporation (TSXV: AVA) (OTC: ARVSF) ("Aurvista" or the "Company") is pleased to announce results from the Company's
recently completed geophysical interpretation
of 2011 magnetic and historic
electromagnetic-magnetic ("EM") INPUTTM airborne geophysical surveys from the Douay Gold Project
(the "Project") within the prolific gold producing Abitibi
Greenstone Belt ("AGB"). A list of the geophysical
and geological technical reports and data sets compiled and
synthesized for the geophysical interpretation are
appended to this press release. The magnetic and EM
INPUTTM responses and target map can be found on
the Company's website www.aurvistagold.com under
Compilation-Target Map #5.
Notable conclusions include:
- Discovery of a number of sizeable EM INNPUTTM
anomalies associated with a mix of felsic and mafic
volcanic rocks that could be associated with base metal mineralization.
The largest which spans a length of 4 km has been marked inside the
ellipse on the Compilation-Target Map #5.
There are a number of
examples of such bi-modal occurrences in the AGB.
- The largest portion of the newly discovered targets is in an area some
6 km in length and 1 km wide and contains a cluster of EM
INPUTTM anomalies and conductors. This cluster
runs from the southern tip of the South Porphyry Zone eastwards to the
limit of the Project (marked by a rectangle on the Compilation-Target
Map #5).
- The discovery of these targets has resulted in Aurvista map-staking a
group of contiguous claims to the southwest of the Project. This has
not been approved as of yet but the Company is taking the necessary
steps.
The original strategy behind the on-going
geophysical and geological interpretation work was to
assist in identifying additional targets with similar
geophysical properties to those associated with
already known gold mineralization on the
Project.
The Company now believes that the
results show the potential for additional and significant
gold and base metal mineralization. Examples of such bi-modal
occurrences in the region include: (1) the Dome, McIntyre, Hollinger gold
deposits of the Timmins Mining Camp with the copper-zinc mineralization of the
Kidd Creek deposit; (2) the Doyon gold deposit along the Cadillac Break of the
Rouyn-Noranda Mining Camp with the Bousquet gold-base metal deposit; and (3) the
Sigma-Lamaque gold deposits of the Val-d'Or Mining Camp with the Louvicourt base
metal deposit.
The bi-modal gold and base metal potential cannot be
overlooked, since the Project is of camp-scale proportion extending in length
for 20 km along the CBDZ, of which only 10 km has been reasonably investigated
for gold only. There are numerous EM INPUTTM conductors outside of
the known gold mineralization corridor. These EM INPUTTM conductors
could potentially be linked to massive sulphides based on the
geological-geophysical association.
The Douay-Style Mineralization ("DSM")
Independent geophysical and geological consultant Yvan
Bussières, P. Eng., of St-Eustache (Quebec), compiled and interpreted the 2011
magnetic and historic magnetic and EM INPUTTM airborne geophysical
surveys from the Project and surrounding area.
The main conclusion of the interpretation is that there is a
direct link between several multi-kilometric magnetic signatures, bedrock
alterations, known gold mineralization and structural patterns. The distinct
association is now termed the Douay-Style Mineralization (the "DSM"). The
DSM has been well defined by historic and recent exploration work, although not
necessarily recognized as such by the previous investigations since the
1970's.
The DSM is comprised of the following:
(1) |
A 10 km long by 3 km wide southeast-tilted
parallelogram-shaped block (at its longest and widest points) covering
an area of 18 km2 located in the centre of the Project and
bounded in all directions by southeast-northwest and northeast-southwest
splay faults of the east-west trending Casa Berardi Fault (the
"Fault"). |
(2) |
Mafic and felsic volcanics with related sediments and
porphyry intrusives that are typical of the AGB gold camps. Some of
the sediments appear as younger conglomerates of the Timiskaming-type (the
Pull-Apart Zone). This is not uncommon as they are present in the Kirkland
Lake and Timmins Gold Mining Camps in the western portion of the
AGB; |
(3) |
Schistose and foliated host rocks due to various
degrees of shearing related to the CBDZ and its numerous faults or
"horsetail faults"; |
(4) |
Highly altered host rocks containing anomalous
amounts of secondary pyrite (an iron sulphide), barite (a barium
sulphate), anhydrite (a calcium sulphate), ankerite (an iron carbonate),
fluorite (a calcium fluoride), and micas (water bearing potassium fluorine
aluminum silicates) and/or clay minerals (water bearing aluminum
silicates); |
(5) |
The geophysical responses are unique to the DSM in
that they consist of chaotic, non-linear, and distorted bands of
strong magnetic highs and complementary lows that result from
the faulting, shearing, and alteration of the host
rocks; |
(6) |
All of the known higher and lower grade gold
mineralization, such as the "Douay West", "10", "20", "531",
"Central", "Main", "Northwest", "Porphyry" and the "South Porphyry" zones;
are clearly identified on the Compilation-Target Map #5. |
(7) |
Of the zones noted above in (6), the gold
mineralization including in the porphyry zones tend to occupy magnetic
lows; and the DSM completely lacks EM INPUTTM
anomalies or conductive horizons. |
Other Geophysical Targets
Several significant targets including those of the DSM-type
remain completely untested outside of the discovered gold mineralization marked
by the parallelogram-shaped block on the Compilation-Target Map #5. The untested
locations run along the remaining 10 kilometric-long area of the CBDZ that lies
within the Project limits.
A number of the 25 newly identified targets in this
interpretation are extensions of already known gold mineralization, however the
Company still considers these viable targets as they could potentially contain
higher grade gold veins and/or disseminated, and strictly disseminated, bulk
gold mineralization, as well as possible Volcanogenic Massive Sulphide ("VMS").
There is one specific VMS target, 6 km long, running along the southeast
boundary of the DMS, which contains a 1 km wide cluster of EM INPUTTM
anomalies or conductors (shown on the Compilation-Target Map #5).
Jean Lafleur, M.Sc., P. Geo., President and CEO of Aurvista
commented "The geophysical interpretation has now shown that the 3 million
ounces of gold in mineral resources outlined in a 2012 NI 43-101 technical
report sits within a 5 km2 segment of a 18
km2 geophysical target area that remains largely
untested for gold. This excludes the remaining untested 10 km trend of the Casa
Berardi Deformation Zone, as well as the massive sulphide targets."
Mr. Lafleur adds "All of the superpit mineralization at the
Dome, Canadian-Malartic and Detour Lake deposits, which are located in the AGB
along with Douay, had extensive historic underground mining which extracted most
of the higher grade gold veins and stockworks. Douay, on the other hand has
never been mined and contains the higher grade gold lenses surrounded by lower
grade gold mineralization in very similar geological environments to the
superpit deposits. Douay lacks the extensive exploration at this time to
substantiate a larger mineral resource. Aurvista's 20 km strike length includes
the Casa Berardi Deformation Zone, a structure similar to the Porcupine-Destor
and Larder Lake-Cadillac Deformation Zones, which hosts numerous gold deposits,
such as the Dome, McIntyre and Hollinger mines in the historic triangle or the
25 km long Val-d'Or and Malartic gold deposit trend."
Aurvista's combined geophysical and geological interpretative
work will continue into 2015. It will include the field testing of the priority
targets determined as part of the interpretation, starting as soon as possible.
The Company is also focused on the engineering and permitting processes to
assess the potential and the economics of bringing the Douay West Zone into
production. At the beginning of Q3-2014 the Company undertook an engineering
program that includes both overburden and rock field investigations for slope engineering and design purposes, a
hydrogeological investigation, an environmental baseline study, a geochemistry
program and mineral resource infill drilling. The infill drilling will lead to a
revised resource estimation that will be appropriate for both an open pit and an
underground mining scenario. Much of the work is nearly complete and will be
reported in mid-2015. The resource modeling will continue to be revised as the
Company receives drill results.
A Company news release issued on December 9, 2014, summarized a
Preliminary Economic Study ("PEA") of the Douay West Zone. The PEA considers
both open pit and underground production options for the advancement of the
Project. The study economics show a pre-tax Net Present Value ("NPV") of $25.0
million at a discount rate of 5% and post-tax NPV of $16.6 million using an
approximate two-year average gold price of US$1,350 per ounce and an exchange
rate of 1.00 $C=0.95 US$. The pre-tax and post-tax internal rates of return
("IRR") for the project are 55% and 40% respectively. The valuations compare to
a current market capitalization of approximately $C 3,000,000.
