Aurania Resources Ltd. (TSXV: ARU)
(OTCQB: AUIAF)
(F
rankfurt
: 20Q)
(“Aurania” or the “Company”)
reports
the Tsenken target
in the Lost Cities
–
Cutucu
Project (“Project”) in southeastern Ecuador
has been
enlarged
by
6
kilometres
(“km”)
;
high
-
grade copper
and
silver has now been found over a
9km long
trend
. Recent grab s
amples
from
boulders in st
r
eams
contain
up to
7
% copper
with
70
grams per tonne (“g/t”) silver
.
Follow
-
up exploration of these streams has
led to the discovery of copper and silver in
outcrop.
Aurania’s
President
, Dr.
Richard Spencer
commented, “
Re
sults from recent sampling have
tripled
the size
of the Tsenken target
to an impressive
length of
9km
.
The
copper
-
silver
mineralization
l
i
e
s in sedimentary
rocks above and to the side of
a
conspicuous geophysical
feature that we believe is a
buried
porphyr
y
cluster
. Our current exploration model is that
copper and silver
from the porphyry cluster spread
into the
enclosing
, permeable
sedimentary rocks
where it was trapped, creating a
more or less flat
-
lying
layer
of
copper
-
silver
–
bearing ro
ck. This
sheet
-
like target should be
relatively simple t
o
drill
.
The potentially
larger target presented by the
covered porphyry would require much deeper drilling
and wo
u
ld be
investigated in a later phase of exploration
.
”
“In addition, scout drilling
at Crunchy Hill is progressing well with
four
holes
completed
and the fifth is
currently underway
.
Samples from the first
three
holes have been dispatched to the laboratory. Core
recovery has been excellent. No assays have been returned at this time.
W
e intend to release
results once
we have
completed
drill
ing
a cluster of holes
.
This will enable us to understand the context of any
mineralization.

Copper

Silver Miner
ali
zation
at Tsenken
C
opper and silver found in the area north of the magnetic feature at Tsenken
(Figure 1)
is contained in
relatively flat
-
lying layers of sandstone and shale. Mineralization is mainly concentrated in layers that
contain carbon in
fossilized
plant
fragments
w
ithin the sedimentary rock. The copper minerals observed
include
malachite
,
chrysocolla, tenorite
,
chalcocite
,
cuprite
and minor bornite and chalcopyrite
.
Grades from boulders in streams
range from
0.8
% copper with
1.3
g/t silver to
9.3
% copper with
185g
/t
silver (
Figure 1
). The
grade of outcrop samples ranges from 0.15% copper an
d
1.1g/t silver to 3
8.6
% copper
and 263g/t silver. The latter s
ample with extreme grade
p
robably represents an isolated pocket of
mineralization akin to a gold nugget, that is atypical
and should not be extrapolated
–
it is extremely unlikely
that this
extreme grad
e extends over any significant distance.
The
magnetic feature
evident at Tsenke
n in
the data from t
he geophysic
al
survey
that the Company flew over the Project
in late 2017
,
is about 5km
long by 3km wide
(Figure 1)
. This is far larger than a typical porphyry. One
explanation for its size
, raised
2
in the
Company’s
January 10, 2019 pr
ess release, is that the Tsenken feature represents a cluster of porphyry
bodies
.
M
ineralization models
will likely
evolve with further exploration of the Project.

Sample Analysis &
Quality Assurance / Quality Control (“
QAQC
”)
Some of t
he
samples were prepared for analysis at ALS
Global
’s
(“ALS”)
lab in Quito, Ecuador
and others
at
MS Analytical
in Cuenca, Ecuador
.
The rock samples were jaw
-
crushed to 10 mesh
(crushed material
passes through a mesh with apertures of
2 millimetres (“
mm
”
)
)
, from which a
one
-
kilogram
sub
-
sample
was taken. The sub
-
sample was crushed
to a grain size of
0.075mm and
a 2
0
0 gram
(“g”)
split was set
aside for analysis.
Aurania personn
el inserted a certified standard pulp sample, alternating with a field blank,
at
intervals of
approximate
ly
20 sample
s
in all sample batches
.
ALS’s preparation lab in Quito sent the prepared samples to its analytical facility in Lima, Peru for analysis
.
Samples prepared by
MS Analytical
were sent to its assay facility in Vancouver for analysis.
A
pproximately
0.25g of
rock
pulp underwent four
-
acid digestion and analysis
for 48 elements
by ICP
-
MS. For the over
-
limit samples, those that had
a
grade of
greater than 1%
copper and 100g/t silver
,
0.4 grams of pulp
underwent digestion
in four acids
and the resulting liquid was diluted
and analy
zed
by ICP
-
MS.
The ultra high
-
grade copper sample
(sample Y003600)
was re
-
assayed by
MS Analytical
, and the value
r
eported in
Figure
1 is the average of the two assays.
T
he re
-
assay
values for copper were 38.68% in the
original and 38.63% in the re
-
assay, and for silver, the values were 263g/t and 262g/t respectively
.
3
ALS
and
MS Analytical
reported that the analyses h
ad passed
their
internal QAQC tests. In addition,
Aurania’s analysis of results from its QAQC samples
showed the
they passed its internal QAQC standards
