Golden Arrow Drill Program Delineates New Target at the Antofalla Silver-Gold-Base Metal Project, Argentina
04 Setembro 2018 - 2:35PM
Golden Arrow Resources Corporation (TSX-V: GRG, FSE: GAC,
OTCQB: GARWF), (“Golden Arrow” or the “Company”) is
pleased to announce the results from the Company’s first diamond
drill program at the Antofalla silver-gold-base metal project in
Catamarca Province, Argentina. The program
included over 3,000 metres of drilling in 11 holes testing the
"Dome Zone," an area of approximately 4 by 4 kilometres. The
program identified a new geologic target at the Cizalla Norte zone,
consisting of silver and base metal mineralization in a shear belt,
comprised of two parallel composite shear zones, and underlying
sandstones. The shear belt incorporates silicified breccias, as
intercepted in hole DDA-07 which returned up to 3 metres averaging
191 g/t silver. In the same drill hole, multiple intersections over
a 70 metre interval in the adjacent sandstone were well
mineralized, including 1 metre averaging 283 g/t silver and 2.1%
zinc, 3 metres averaging 131 g/t silver, and 1 metre averaging 110
g/t silver, 1.7% lead and 4.1% zinc. The hole ended in
mineralization at 275 m depth.
“We are encouraged by the program results,
particularly from this new shear zone which appears to have some
similarities to mineralization at Chinchillas. With just two drill
holes into this 650-metre-long shear belt the target remains open
for expansion in both directions and to depth. In addition, the
array of current targets in the Dome Zone covers an area of over
1600 hectares, so further geophysics and follow-up drilling is
required to properly determine the full potential of the
project. We have made the second option payment to the vendor
so that we are able to proceed.” commented Brian McEwen, Golden
Arrow’s Vice President of Exploration and Development.
Program Details
The Antofalla Project includes a Miocene Dome
complex hosted in Permian conglomerates and sandstones, with
signatures of both high and low sulphidation epithermal
mineralization. Mineralization has been identified in several areas
of the Dome Zone. A review of the initial data indicated
similarities to the geologic model for Golden Arrow’s Chinchillas
silver project in Jujuy province which is currently being developed
through a joint venture between Golden Arrow and SSR Mining
Inc.
(https://goldenarrowresources.com/projects/jujuy-province/chinchillas).
A preliminary geological model for Antofalla is shown in Figure
1.
Golden Arrow completed 11 diamond drill holes on
4 main target areas within the Dome Zone (see Figure
2). Intervals with >20g/t silver or >0.1 g/t gold
are summarized in Table 1, with hole location information in Table
2. The Cizalla Norte target has emerged as a new focus of
exploration potential at the project, as drilling confirmed the
discovery of significant silver-zinc mineralization in a shear
belt/zone as well as along the contact with, and in, the underlying
Permian sandstones. The mineralized contact between the flow
dome and the sandstone basement is a similar environment for
mineralization as is seen at the Chinchillas silver-lead-zinc
deposit.
A geological interpretation of results from all
targets is summarized below:
- Cizalla Norte (previously Domos
Norte). This target is in the north part of the Dome Zone. It
includes a composite shear belt of approximately 650 m long with an
azimuth of 110° and dipping 50-60° to the SW in dacitic lava flows.
This belt consists of two parallel shear zones, each of 35 to 40
metres width, situated 30 metres apart. Silver mineralization
appears to be related to hydrothermal breccias and quartz veinlets
within the shear zones. Channel sampling of surface trenches cut
the Northeast shear zone obliquely, and returned an average of 61.8
m @ 62 g/t Ag (41 samples averaging 1.5 m wide; 6 samples returned
> 100 g/t Ag). Holes DDA-05 and DDA-07 are parallel holes
drilled into this target, 110 m apart. Both holes intercepted both
shear zones. The Southwest shear zone was first detected by these
holes because at surface it is covered by alluvium material.
Hole DDA-05 encountered isolated intervals of mineralization
with up to 2 m @ 116 g/t Ag. Hole DDA-07, 110 m northwest of hole
DDA-05, was drilled across the contact through the underlying
Permian sandstones. In the shear zone cut by hole DDA-07 there are
silicified breccias with up to 3 m @ 191 g/t Ag. At the contact
with, and for 70 metres into, the Permian sandstones, from 205 to
275 metres deep, drilling intercepted a sphalerite/galena stockwork
zone containing higher silver-zinc values, including 1m @ 283 g/t
Ag and 2.1% Zn, 3 m @ 131 g/t Ag and 1 m @ 110 g/t Ag, 1.7% Pb and
4.1% Zn. A cross-section including hole DDA-07 is shown in Figure
3. The presence of the shear belt close to the contact of the
underlying Permian sandstones is a new target just partially tested
with these holes. Of particular note is that hole DDA-07 ended in
mineralization at 275 m depth. Both ends of the shear belt and to
depth are open and require testing with additional drill
holes.
- Colorada Breccia. This is a breccia
vent target approximately 200 m in diameter characterized by
sulphide-mineralized lenticular to irregular shaped hydrothermal
breccias. Of the four holes drilled at this target (DDA-02,
DDA-03, DDA-10 and DDA-11), only DDA-11 intercepted anomalous
values, including 12 m @ 0.31 g/t Au g/t, 109 g/t Ag, 0.4 % Pb and
2 m @ 0.54 g/t Au, 355 g/t Ag and 2.1% Pb.
- Filo del Volcan. This target
includes diatreme breccias intruding dacitic pyroclastic flows. The
three drill holes completed on this target (DDA-01, DDA-04 and
DDA-08) encountered several high-grade intervals including 2 m @
145 g/t Ag. This target is linked with the Colorada Breccia by the
ENE-WSW fractures which may have controlled the emplacement of
these bodies. Hole DDA-09 was drilled in-between the targets and
intercepted several hydrothermal breccias with grey silica and
pyrite. Silver values were generally low in this hole but anomalous
gold intervals (i.e. 14 m@ 0.16 g/t Au), similar to the Colorada
Breccia target, were encountered.
- Filo Blanco This target is a silica
cap. The IP/Resistivity survey indicated a chargeability
anomaly situated just below the highest point of the system,
coincident with a high resistivity anomaly, at 600 metres below
surface. The chargeability anomaly was postulated to represent the
feeder of the epithermal system or a porphyry body. Drill hole
DDA-06 was drilled to 627 metres to test this target. In the first
250 metres a pervasively silicified dacitic flow was encountered,
underlain by dacitic lava flows and pyritic sandstones down to 450
metres. Below 450 metres, and until the end of the hole, lava flows
with disseminated pyrite were encountered, but with no significant
mineralization.

Methodology and QA/QC
Drill core was split and half core samples were
shipped for preparation and analysis at Alex Stewart-Mendoza, an
internationally recognized assay service provider. Samples were
assayed for gold by Fire Assay/Atomic Absorption finish and
analyzed for a multi-element package by ICP-OES following a four
acid digestion. Silver results >100 g/t Ag were re-analyzed by
fire assay with a gravimetric finish on 50-gram samples. Lead and
zinc results >10,000 ppm were re-analyzed by a three acid
digestion and ICP-OES detection. The Company follows industry
standard procedures for the work carried out on the Antofalla
Project, with a quality assurance/quality control (QA/QC) program.
Blank, duplicate and standard samples were inserted in each batch
of samples sent to the laboratory for analysis. Golden Arrow
detected no significant QA/QC issues during review of the data.
Qualified Persons
The results of the Company's exploration program

Development to the Company. Mr. McEwen is a Qualified Person
as defined in National Instrument 43-101, and has reviewed and
approved the contents of the news release.
