RECONNAISSANCE DRILLING DELIVERS GRADES UP TO
2.19% CuEq AT FORTUNA PROJECT
Culpeo Minerals Limited (Culpeo or the Company) (ASX:CPO, OTCQB:CPORF) is pleased to
report that reconnaissance drilling has intersected near-surface, high-grade copper
mineralisation grading up to 2.19% CuEq at the Vaca Muerta and El Quillay North Prospects
within its 80%-owned Fortuna Project (the Project) in Chile.
The prospect areas are part of a suite of promising exploration targets within an underexplored copper belt, which the Company is aggressively exploring.
HIGHLIGHTS
• Multiple zones of shallow, high-grade copper mineralisation intersected.
• Mineralisation hosted within broad zones of favourable host rocks.
• Highlighted downhole intersections include:
• 13.3m @ 0.59% CuEq from 20m;
• 4m @ 0.65% CuEq from 45m;
• 7m @ 0.67% CuEq from 55m, including 1m of 2.19% CuEq; and
• 2m @ 1.33% CuEq from 95m.
• Drilling ongoing at Lana Corina Project within >3km prospective corridor.
Culpeo Minerals’ Managing Director, Max Tuesley, commented:
“To drill and intersect multiple zones of shallow copper mineralisation on our first pass reconnaissance drilling
program at Vaca Muerta is extremely positive and highlights the significant potential of the target area. This
result coupled with the ongoing exploration success at El Quillay indicates that the Fortuna Project continues to
provide potential for a major copper discovery with three distinct targets now identified that include: breccia
hosted copper mineralisation at El Quillay and Vaca Muerta, porphyry copper and gold at La Florida and highgrade structurally controlled copper and gold at Piedra Dura.”

EL QUILLAY DRILLING PROGRAM
Assay results from the second hole drilled at El Quillay North returned 13.3m @ 0.59% CuEq
from 20m downhole (Figure 1 and 2, Table 1 and Appendices C & D), confirming further
shallow copper mineralisation within the target. Previous drillhole CMEQD002 returned 26m
@ 0.81% CuEq from 29m including a high-grade zone of 4m of 1.87% CuEq from 51 to
55m1.
Figure 1: Plan view with results of CMEQD001 and CMEQD002.1,2,3,4,5,6
These drilling results highlight the significant widths of outcropping mineralisation that are
hosted within the El Quillay Fault. This structure is known to have at least 3km of strike extent,
the majority of which remains undrilled and with the discovery of mineralisation at El Quillay
East2 and geophysical targets to the west6, the Company has initiated the next phase of field
work. This will include detailed surface mapping and sampling, trenching in areas prior to
drilling and ground truthing of targets identified from historic geophysical data.

VACA MUERTA DRILLING PROGRAM
Positive assay results have been returned from reconnaissance drilling at the Vaca Muerta
Prospect. A total of approximately 330m of diamond drilling was completed in two holes at
two separate early-stage targets. Drillhole CMVMD002 was designed to test the known
surface copper mineralisation at the prospect area and intersected multiple zones of
copper mineralisation from shallow depths. The mineralised zones are closely spaced and
present over moderate widths down hole (Figure 3, Table 2, and Appendices C & D).
Encouragingly, the mineralised lenses are hosted within a very broad zone of highly altered
and brecciated volcanic rocks which are considered to be favourable host units. A highgrade intercept of 1m @ 2.19% CuEq was returned from a zone of brecciated volcanics
from 55m. Further work is planned in the form of detailed surface mapping with a focus on

SECTION 1 SAMPLING TECHNIQUES AND DATA
Criteria
JORC Code explanation
Commentary
Sampling
techniques
Nature and quality of sampling (e.g. cut
channels, random chips, or specific specialised
industry standard measurement tools
appropriate to the minerals under
investigation, such as down-hole gamma
sondes, or handheld XRF instruments, etc.).
These examples should not be taken as
limiting the broad meaning of sampling.
El Quillay
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.
Aspects of the determination of mineralisation
that are Material to the Public Report. In
cases where ‘industry standard’ work has been
done this would be relatively simple (e.g.
‘reverse circulation’ drilling was used to obtain
1 m samples from which 3 kg was pulverised
to produce a 30 g charge for fire assay’). In
other cases more explanation may be
required, such as where there is coarse gold
that has inherent sampling problems.
Unusual commodities or mineralisation types
(e.g. submarine nodules) may warrant
disclosure of detailed information.
• 17 holes for a total of 4,683.33
meters, were completed historically.
• Sampling and analysis was
undertaken for 570 samples, 570
analyses for copper; 480 analyses
for gold and 26 analyses for silver.

relation to
geological
structure
• No twin holes have been completed
due to the early stage of the project.
Whether the orientation of sampling achieves
unbiased sampling of possible structures and
the extent to which this is known, considering
the deposit type.
• Historic drilling and channel
sampling orientations are not
considered to be biased with several
drilling orientations used.
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.

Relationship
between
mineralisation
widths and
intercept lengths
In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (e.g. cutting of
high grades) and cut-off grades are usually
Material and should be stated.
If the geometry of the mineralisation with
respect to the drillhole angle is known, its
nature should be reported.
If it is not known and only the down hole
lengths are reported, there should be a clear
statement to this effect (e.g. ‘down hole length,
true width not known’).
• Only raw assay results have
been reported.
• Only down hole lengths have
been reported with respect to
drilling intercepts, true width of
mineralisation is unknown.
Diagrams
Appropriate maps and sections (with scales) and
tabulations of intercepts should be included for
any significant discovery being reported These
should include, but not be limited to a plan view
of drill hole collar locations and appropriate
sectional views.
• Diagrams are included in the
main body of the report.
Balanced
reporting
Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and high
grades and/or widths should be practiced to
avoid misleading reporting of Exploration
Results.
• Results have been reported for
the main elements targeted
(Cu, Ag, Au, and Mo). All
historic drillhole locations are
reported for context.
Other substantive
exploration data
Other exploration data, if meaningful and
material, should be reported including (but not
limited to): geological observations; geophysical
survey results; geochemical survey results; bulk
samples – size and method of treatment;
metallurgical test results; bulk density,
groundwater, geotechnical and rock
characteristics; potential deleterious or
contaminating substances.

Technical Details
Copper Equivalent (Cu Eq) values: Assumed commodity prices for the calculation of Copper
Equivalent (Cu Eq) is Cu US$3.00/lb, Au US$1,700/oz, Mo US$14/lb and Ag US$20/oz. Recoveries are
assumed from similar deposits: Cu = 85%, Au = 65%, Ag = 65%, Mo = 80%, Cu Eq (%) was calculated
using the following formula: ((Cu% x Cu price 1% per tonne x Cu recovery) + (Au(g/t) x Au price per
g/t x Au recovery) + (Mo ppm x Mo price per g/t x Mo recovery) + Ag ppm x Ag price per g/t x Ag
recovery)) / (Cu price 1% per tonne x Cu recovery). Cu Eq (%) = Cu (%) + (0.54 x Au (g/t)) + (0.00037
x Mo (ppm)) + (0.0063 x Ag (ppm)). It is the Company’s opinion that all elements included in the
metal equivalents have a reasonable potential to be recovered and sold.
The reported composite intersections for the drilling are generally calculated over intervals >0.2%
Cu where zones of internal dilution are not weaker than 2m < 0.1% Cu, no top cut has been applied.
Bulked thicker intercepts may have more internal dilution between high-grade zones. Isolated
mineralised intersections less than 2m in downhole length have not been reported. Higher grade
zones within the reported composite intersections are included where the average grade of the
internal zone is approximately 4x grade of the reported grade for the composite intersection.
