IP Survey Identifies Polarization Anomalies (Potential Mineralization) in
Known Areas of Gold Mineralization;
Possible Intrusive Centre Identified by Resistivity Methods
(Toronto, Ontario – March 26, 2018) Avidian Gold Corp. (TSXV:AVG) (the “Corporation”
or “Avidian”) is pleased to provide an overview and comments on the results of a 2017 Induced
Polarization survey completed at its 100% owned Golden Zone project in Alaska. The results
were reviewed in conjunction with historical geophysical data including airborne
electromagnetic and magnetic data and Controlled Source Audio Magnetotellurics (“CSAMT”)
results.
In 2017, a time domain Induced Polarization (“IP”) survey was completed on the Golden Zone
project covering five areas: Riverside, Breccia Pipe Deposit area, Bunkhouse, Copper King and
South Long Creek (see Figure 1), using a variety of array and dipole separations. A total of 43
km of line was surveyed. This data was incorporated and compiled with a 1996 aerial
geophysical survey that included total magnetics and five frequencies of electromagnetic (“EM”)
data at 100 m line spacing plus a 1982 CSAMT survey. The combined surveys delineated
magnetic lows and resistive highs interpreted to represent intrusive events potentially related to
the areas of known gold mineralization and to as yet undiscovered mineralization (see Figure 2).
The airborne magnetic data also provided excellent insight into the structural trends on the
property and highlighted the significance of structures in the known mineralized areas. The
results of these surveys along with field geological work led to the identification of many of the
2017 drill target areas as well as new areas that will require follow-up work during 2018.
Highlights from the geophysical review including the 2017 IP survey are:
1) Magnetic data indicates a strong NE-SW structural trend on the property with orthogonal
cross cutting faults often in the area of known mineralization (see Figure 2). It is
believed the cross-cutting faults have provided the “plumbing system” to allow
mineralized fluids to flow to surface, such as in the area of the known Breccia Pipe
Deposit.
2) A prominent resistivity high identified in the 1982 CSAMT data suggests a intrusive
event to the immediate northwest of the Breccia Pipe Deposit. Known mineralization at
the Breccia Pipe West, the Breccia Pipe Deposit, Bunkhouse and Mayflower areas are
found along the eastern edge of this interpreted intrusive (see Figure 3). The 1996
airborne EM and Avidian's 2017 mapping corroborate the presence of this major
intrusion; further geophysical work is necessary to fully delineate it.
3) The 2017 IP survey was conducted on specific target areas that lie within the 8 km long
trend over which gold mineralization grading > 1 g/t Au can be traced (see January 15,
2018 press release). In each of the areas surveyed, polarization/resistivity anomalies have
been identified in association with known mineralization. With further expansion of the
IP coverage it may be possible that line to line correlation will be established along the
roughly 8 km strike length of known mineralization structurally bound by the Golden
Zone and Long Creek Corridors.

4) In four of five areas surveyed (Riverside, Breccia Pipe Deposit, Bunkhouse and Copper
King), pronounced chargeability anomalies were delineated over strike lengths in excess
of 500 m. Given the proximity of these anomalies to known gold mineralization it is
expected, pending further geologic follow up, that they will be drilled in 2018.
5) In the vicinity of the Breccia Pipe Deposit, the 2017 IP survey identified multiple
anomalies sub paralleling the main NE-SW structural trend of the area. These anomalies
fall on the outer edge of the CSAMT resistivity high that is interpreted to reflect an
intrusive centre (see Figure 3). Drill testing of some of these anomalies in 2017 led to the
intersection in hole GZ17-10 a core length of 21.6 m of 1.46 g/t Au in a previously
unknown mineralized conglomeratic unit (see January 18, 2018 press release). This
stratigraphic unit represents a new substantial target on the property that has not been
drill evaluated and is open in all directions.
6) It should be noted that additional mineralized conglomeratic units have been identified at
the Long Creek occurrence, approximately 4 km to the south of hole GZ-17-10 where a
historical trench (orientated in a NNW-SSE direction, perpendicular to the geologic units
that trend in a NEE-SWW direction) uncovered a conglomeratic unit that retuned 6.1 m
of 13.8 g/t Au, 34.4 g/t Ag and 0.85% Cu. This conglomerate has never been evaluated
on strike or drill tested. Mineralized conglomerate is also known at the Copper King
prospect. Conglomerates are common on the Golden Zone property and Avidian
considers them to be a potential host for a style of deposit that has not previously been
explored for.
7) The newly discovered “Breccia Pipe West” occurrence (grab sample of 14.64 g/t Au and
355 g/t Ag) located 500 m west of the known “Breccia Pipe Deposit” has a coincident
NE-SW trending chargeability/resistivity anomaly that has not been drill tested.
8) In the Copper King and Long Creek mineral occurrence areas, the IP survey in
combination with the historical airborne magnetic survey identified a number of magnetic
low features interpreted to be shallow intrusives, adjacent to the known mineralization
which have associated chargeability highs. The IP results suggest that areas of known
mineralization have potential to develop reasonable width and depth extent. In addition
to the many high-grade samples in the Copper King mineral occurrence (see January 15,
2018 press release) a grab sample adjacent to a quartz eye stockwork granite returned a
value of 4.8 g/t Au, 106 g/t Ag and 1.4% Cu. This sample is adjacent to an identified
IP chargeability high.
9) At South Long Creek only one 2 km long reconnaissance line was completed as a test to
determine how it relates to known mineralization. Multiple anomalies were identified,
with the most significant anomaly coincident within the main area of known
mineralization. A historical trench (orientated in a NW-SE direction, perpendicular to the
geologic units that trend NE-SW) returned 3.0 m of 2.74 g/t Au and174.9 g/t Ag in the
immediate area of the IP anomaly. Survey coverage will be extended in 2018.

The geophysical review in conjunction with the 2017 IP survey has identified multiple areas of
geophysical significance within the 8 km long mineralized trend at Golden Zone. In all cases the
most prominent geophysical anomalies are coincident with known areas of mineralization. In
addition, new geophysical anomalies that have yet to be sampled or evaluated have been
identified in these known areas. In all areas additional coverage (in-fill lines) and detailed
geological work will be required to assist in prioritizing drill targets.
Background
The Golden Zone property lies within the gold endowed Tintina Belt, is located 320 km north of
Anchorage, Alaska and is accessed by a 16 km road west of the main transportation route
between Anchorage and Fairbanks. The property is comprised of a 2,960 acre Uplands Mining
Lease with an expiry date of 2050, surrounded by 92 State of Alaska claims totaling 11,600 acres
and a nearby, non-contiguous, 40-acre Mill Site Lease.
Gold mineralization on the property is found in breccias, veins and shear zones, skarn and other
replacement styles of mineralization. These all appear to be of igneous affiliation and are all
spatially related to Cretaceous age porphyritic intrusives.
