June 19th, 2018 (TSX Venture: LRA) - Lara Exploration Ltd. (“Lara” or “the Company”), is pleased to
report that its final hole of the Phase -1 scout drilling program, hole PDH-18-03, intercepted 130.41m.
between 68.05m and 198.46m down hole, with an average grade of 0.88% copper and 90ppb gold, or
0.93 % copper equivalent “CuEq”, within a wider zone of 284.71m from surface averaging 0.48% Cu and
48 ppb Au.
Miles Thompson, President and CEO of Lara commented: “We are pleased to see t he notable trend of
increasing grade as the mineralization plunges shallowly under cover and encouraged also to have hit some
more massive chalcopyrite veining.”

CuEq values for by -product gold are calculated using a copper price of US$3.29/lb and a gold price of
US$1,300/oz. No allowance is made for losses in a normal mining situation. Intervals are down hole intervals
and are believed to be close to true width.
PDH-18-03 was collared approximately 255m west of 18-02 (results of which were reported in Lara news
release of April 24, 2018) on the same section and drilled eastward back towards it as a scissor hole at an
angle of -50 degrees. The hole was designed to test an interpreted ground EM conductor and part of the
strong soil copper anomaly extending to about 150m to the west of drill hole 18 -02. Interpretation of the
geological and assay results for drill hole 18-02 had indicated that if the mineralized structures intersected
in that hole had a moderate or steep westerly dip , then the copper in soil anomaly would have only been
partially drill tested by hole 18-02.
Drill hole 18 -03 intersected a thick zone of hydrothermal alter ation and vein stock works carryi ng

mineralization above a 0.3% Cu cut-off from 68.05m down to 196.46 m (130.41m) at a weighted average
grade of 0.88% Cu and with 90ppb Au. Within this interval the re are numerous sub-intervals from about
1m to more than 25m wide with greater than 0.5% Cu. Two intervals of note within this wide zone of
copper mineralization are:
• 156.3m to 157.7m: 1.4m at 22.33% Cu associated with two veins (core lengths of 84cm and 19cm,
respectively) of massive chalcopyrite cutting the mafic host. This is the first significant occurrence
of massive chalcopyrite veining encountered during the drill program and is coincidental with the
deepest drill intersection of the mineralized system made to date; and
• 169.75m to 198.46m: 28.7m at 0.93% Cu and 107ppb Au associated with a strong zone of
disseminated and fracture-vein controlled chalcopyrite. A similar zone of high-grade disseminated
copper was noted in drill hole 18 -02 at the base of that mineralized zone. That interval assayed
37.71m at 0.72% Cu and 106ppm Au and the true width of that zone is interpreted to be about 30m,
a similar width to that intercepted by hole 18-03, considering the new geological interpretation of
a moderate west dip for the attitude of mineralized body. The grade increase for copper going down
the dip is encouraging but will need to be confirmed by future drilling.
Although the host rocks are strongly hydrothermally altered and have narrow (1 m to 2m-wide) higher-
grade copper mineralized zones between 0.3 % and 0.6% Cu above and below the main zone of
mineralization, there are only two other zones with over 3m true thickness with grades above the 0.3% Cu
cut-off; one at 56.72m with 3.13m at 0.57% Cu, the other at 271.95m with 8.28m at 0.35% Cu. A shear or
thrust zone, 10m to 20m wide, with strong biotite alteration and quartz veining occurs approximately 30m
below the base of the mineralization. The controls for the emplacement of the mineralization are still not
known with any certainty, although it would appear that the gabbro intrusive had been more susceptible to
brittle fracturing than the enclosing meta -volcanic rocks and this fracturing facilitated the ingress of the
mineralizing fluids.
The presence of incipient zones of brecciation and hydraulic fracturing logged over only a few centimeters
to no more than two meters in down hole intervals in the cores of this hole and in cores of the previous
holes, is suggestive that the part of the system tested by th is scout drilling program is related to a more
distal part of a major hydrothermal alteration system that could be interpreted to be at greater depth in this
system. Other deposits in the Carajás that have been developed in a brittle fracture regime, like Vale’s
Sossego deposit, are more characterized by wide (tens of meters) hydrothermal breccia zones , where
chalcopyrite occurs as breccia matrix cement or as major veins up to several meters wide.
Geological plans and a cross section for 18 -03 also incorporating the previous hole 18 -02, as well as the
historic drill hole F -74 are posted on the Company’s website at www.laraexploration.com. The section
shows that the gabbro body is in the order of 180m to 200m thick and has a low angle (30-40 degrees) dip
to the west. The contacts with the mafic to intermediate meta-volcanic country rocks are not discernable in
cores or outcrop because of the intense alteration (chlorite, biotite, actinolite and epidote) that commonly
forms a fine -grained mass that renders the o riginal coarse-grained gabbro rock similar to a fine grained
mafic-intermediate volcanic rock. The attitude of the main mineralized zone at 0.3% Cu cut-off appears to
mimic that of the gabbro intrusive. Drill hole 18-03 has intersected the mineralization at between 150m and
3
200m down dip from the surface and the inference is that the mineralized zone remains open to depth. This
will need to be confirmed by subsequent drill programs.
Insufficient drilling has been conducted to date to determine the width of the body of the copper
mineralization. The earlier drill holes 17 -01 and 17 -02 indicate that copper mineralization extends to
approximately 100m to the south of the central drill hole 18-02 to 18-03 cross section and anomalous copper
values analysed in mafic saprolite grab samples suggest it could be as much as 150m to 200m to the south
in places where the near surface mineralization is mapped as being hosted by intensely hydrothermally
altered leucogranite.
No drilling has tested the north sector, but rock grab and chip sampling of outcrops of relatively fresh
hydrothermally altered mafic rocks exposed in the creek from 100 m to 130m to the north of the central
section have returned anomalous copper values from a few hundred to a maximum of 2768ppm Cu. A grab
sample of saprolite from a weathered mafic rock at 150m to the north also returned an anomalous copper
value of 1625ppm Cu. These approximate limits are roughly coincident with the outline of the 500ppm Cu-
in-soil anomaly contour.
The copper mineralization occurs as chalcopyrite, as disseminations and as vein filling in a stock-work-like
fracture vein set, with the higher grades usually closely associated with zones, centimeters to meters-wide,
of strong K-feldspar–magnetite alteration that is flanked by wider zones of biotite and chlorite alteration in
the gabbro and mafic meta-volcanic host rocks.
Sampling methodology, Chain of Custody, Quality Assurance and Quality Control
All the rock channel and drill core sampling were carried out by or under the supervision of the Company’s
Vice-President Exploration and the chain of custody of the samples and drill core from the project area to
the Company’s sample preparation facility in Can ãa dos Carajás was continuously monitored. Sample
intervals for channel sampling varied between 2m and 4m and for drill core the sampling interval varied
from a little less than 1m to a maximum of 1.5m being guided by the degree of copper mineralization and
rock types.
Blank and certified reference materials were inserted approximately every 20th sample and the company
routinely reanalyses laboratory pulps and crushed rejects for a number of samples from previous sample
batches with each new sample batch. The samples were delivered to SGS -Geosol in Parauapebas where
they were crushed and pulverized. Sample pulps are dispatched to by SGS -Geosol to their own analytical
laboratory at Vespasiano, near Belo Horizonte, Minas Gerais State, Brazil. The pulps are subjected to Agua
Regia digestion with copper and 36 other elements being determined by ICP. Gold was determined by fire
assay fusion and an atomic absorption (AAS) finish on a 50-gram charge. Copper values above 1% Cu are
determined by fusion with sodium peroxide with an ICP OES finish or by multi-acid digestion with an AAS
finish with check analyses by XRF on lithium tetraborate -ammonium nitrate fused samples. SGS -Geosol
routinely runs, and reports, results for a number of certified copper and gold standards and blank samples
with each sample batch.
Check assays for copper and gold determinations are routinely carried out on a number of reject material
samples from SGS-Geosol at a second commercial laboratory in Parauapebas.
