ASX ANNOUNCEMENT

18 September 2014

ENCOURAGING MOLYBDENUM MINERALISATION EXTENDS DRILLHOLE HIGHLIGHTS

The Company is pleased to update progress of the Stage 2 drilling program and the additional exploration efforts at the Alumbre Project in Peru.

Key points are as follows:

  • The second drillhole (ALDD14007) has progressed to a depth 432m with Chalcopyrite and Molybdenite observed in veinlets.

  • ALDD14007 has been extended due to the encouraging alteration and mineralisation observed in drill core consistent with a mineralised porphyry system.

The Alumbre Project is a Au-Cu-Mo porphyry system located 70km southeast of Trujillo in northern Peru. The project is serviced by the nearby Pan Americana Highway and enjoys access to good infrastructure in the project area.

Four diamond drill holes are planned with a total of 1,900m (as illustrated in Figure 1 and summarised in Table 1). The Company’s proposed drill holes will target an area below anomalous surface copper, gold and molybdenum geochemistry and intersecting the modelled MVI anomaly which is a significant feature several kilometres in strike length.

The Company has conducted substantial work on the Alumbre Project including recent magnetic susceptibility readings, magnetic modelling using the MVI method, geochemistry, structure, alteration and geophysics. All combine to indicate the district-scale potential of the Alumbre project. Indications are that a significant sulphide-bearing porphyry system exists at Alumbre.

The second drill hole in this drill program, drillhole ALDD14007 (Table 1 and Figure 1) is currently at depth 432m. The drillhole intersected sedimentary cover from surface to 82.45m. These overburden rocks appear to have been deposited as a mass flow due to a major flooding event. The cover material is comprised mainly of intrusive granodiorite rocks and clay.

Below the cover material, volcanic rocks were intersected from 82.45m. These are mainly andesitic tuffs. The andesite has evidence of hydrothermal alteration, which is generally phyllic. The phyllic alteration is represented by abundant quartz and sericite.

ASX:PRA | PROMESA.COM.AU Page 1

==> picture [126 x 29] intentionally omitted <==

Pyrite mineralisation varies from 1% to 4% to a depth of 404m. Minor chalcopyrite occurs at 283.35m (Figure 2). Molybdenite occurs in veinlets from 404m (Figures 2 to 4). The drillhole is currently at 432m and continues. The mineralisation, alteration and structure observed thus far are typical of volcanic rocks which have been affected by an underlying intrusive porphyry. The alteration has been increasing with depth and the Company expects the alteration intensity to become potassic with secondary biotite, as drilling continues. The drillhole has been extended beyond the planned 380m due to the encouraging alteration and mineralisation observed in the drillcore.

The company proposes to drill hole Planning 3 to target extensions to the mineralised intercept of 7m @0.72% Cu encountered in drillhole ALDD14005. Drill hole Planning 4 will be a sub horizontal drillhole.

All drill platforms and access are completed. All social, community and regulatory requirements have been adhered to and the environmental permit (DIA) has been received.

In order to maintain momentum with our drilling efforts, the company has commenced work on a Semi Detailed Environmental Impact Assessment that will extend our area of influence four fold around our current permits. This will enable the company to plan its drilling beyond the current approved 20 platforms.

The Company looks forward to providing investors with further regular information on the drill program at Alumbre as drilling progresses. For further information on the Project please visit our website www.promesa.com.au or contact Ananda Kathiravelu.

Section 1 Sampling Techniques and Data – Alumbre Project

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.
Promesa Limited (“Promesa” or “Company”) has completed
first stage diamond drilling program which was announcement
to ASX 8 May 2014 at the Alumbre Project area.
This announcement contains the proposed the announcement
of the Stage 2 drill program and the hole parameters for the
Stage 2 drill program refer to Table 1 and Figure 1.
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or systems
used.
The drill hole locations were determined by handheld GPS both
during planning and execution.

Criteria JORC Code explanation Commentary
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 (eg submarine nodules) may warrant
disclosure of detailed information.
Drill core will be inspected and logged in detail noting visible
mineralisation, lithology and alteration. Drill core was logged
in detail. All sampling will be carried out under the Companys’
protocols, with industry best practice QAQC procedures.
Drilling techniques Drill type (eg core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic,
etc) and details (eg core diameter, triple or
standard tube, depth of diamond tails, face-
sampling bit or other type, whether core is
oriented and if so, by what method, etc).
The drilling rig is a Boart Longyear LF70. Rock conditions are
very good and a standard diamond core tube is being used.
Drill hole orientations in the current hole are taken each 50m.
HQ and NQ diameter drillbits are used. Stage 1 drilling had
excellent core recovery. It is expected that the same recovery
will be same for stage 2.
Drill sample
recovery
Method of recording and assessing core and chip
sample recoveries and results assessed.
Measures taken to maximise sample recovery and
ensure representative nature of the samples.
Whether a relationship exists between sample
recovery and grade and whether sample bias may
have occurred due to preferential loss/gain of
fine/coarse material.
Core barrel length and core length measurements will be made
during the course of the program an all significant core loss
reported. At this stage no significant core loss has occurred.
Drill core will be cut and sampled after initial logging, core
recovery and rock quality determination measurements.
Not applicable as no core loss was experienced.
Logging Whether core and chip samples have been
geologically and geotechnically logged to a level of
detail to support appropriate Mineral Resource
estimation, mining studies and metallurgical
studies.
Drill core will be inspected, lithologies and mineralisation styles
noted. Core is being logged in detail. Rock quality and fracture
densities are noted.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
Logging of drill core is qualitative. Drill core will be logged in
detail and photographed.
The total length and percentage of the relevant
intersections logged.
100% of drill core will be inspected and logged. 100% of core
referred to in this announcement was inspected and
photographed.
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether quarter,
half or all core taken.
Drill core is being half cut with a diamond saw. The half core
will be sampled.
If non-core, whether riffled, tube sampled, rotary
split, etc and whether sampled wet or dry.
Not applicable
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
Drill core subject to this announcement will be sampled on 1
metre interval except where mineralisation is extreme, in which
case smaller sample lengths will be used.
Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
All core is sampled and duplicate samples are routinely taken
to ensure representivity
Measures taken to ensure that the sampling is
representative of the in situ material collected,
including for instance results for field
duplicate/second-half sampling.
All core is sampled.
Whether sample sizes are appropriate to the grain
size of the material being sampled.
Sample size is 1 metre drill core intervals, grain size is 0.2 to
3mm, vein widths are generally 1mm to 5mm and occasionally
15cm, therefore sample size is appropriate

Criteria JORC Code explanation Commentary
Quality of assay
data and
laboratory tests
The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or
total.
Acme Labs are used with appropriate methods and protocols.
For geophysical tools, spectrometers, handheld
XRF instruments, etc, the parameters used in
determining the analysis including instrument
make and model, reading times, calibrations
factors applied and their derivation, etc.
No geophysical tools were used to determine any element
concentrations.
Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory
checks) and whether acceptable levels of accuracy
(ie lack of bias) and precision have been
established.
Blanks, duplicates and certified standards are inserted
approximately every 10 samples. A selection of pulps was sent
for umpire assaying.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Significant intersections will be verified by company senior
personnel.
The use of twinned holes. No twinned holes are warranted at this stage as the current
program is exploration drilling. When a resource drilling
commences twinned holes may be considered.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
All data is logged in paper form then entered into an access
database. Standard data validation procedures are built into
the program at the data entry stage. Further data validation
occurs within the MapInfo environment.
Discuss any adjustment to assay data. No adjustment have been made.
Location of data
points
Accuracy and quality of surveys used to locate drill
holes (collar and down-hole surveys), trenches,
mine workings and other locations used in Mineral
Resource estimation.
Drill hole collars were located using handheld GPS and
checked on several occasions through the program.
Specification of the grid system used. UTM grid, Datum WGS84 zone 17 is used.
Quality and adequacy of topographic control. All drill holes are located by handheld GPS. The topographical
control is considered adequate for this initial phase of
explorations and drilling.
Data spacing and
distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is
sufficient to establish the degree of geological and
grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation procedure(s)
and classifications applied.
Whether sample compositing has been applied.
Project is at an early exploration stage. Drill hole spacing of
approx. 300m sufficient for the current stages of drilling.
Mineral Resource and Ore Reserve estimation are not
calculated from current work. Future drill results will determine
the required spacing for a Mineral Resource estimation.
No compositing has occurred.
Orientation of data
in relation to
geological
structure
Whether the orientation of sampling achieves
unbiased sampling of possible structures and the
extent to which this is known, considering the
deposit type.
The drill holes subject of this announcement were planned to
intersect a geophysical chargeability anomaly / magnetic
susceptibility associated with intrusive and volcano-
sedimentary rocks bearing low-grade, bulk mineable
replacement, disseminated or stockwork style mineralisation.
No structural bias is expected.
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.
Geological information to date suggests that there will be no
sampling bias when sampling occurs.
Sample security The measures taken to ensure sample security. A chain of custody of samples is used and managed by
Promesa. Samples are stored on site and either delivered by
Promesa personnel to the assay laboratory in Trujillo or Lima in

Tracking sheets have been set up to track the progress of
batches of samples.
Audits or reviews The results of any audits or reviews of sampling
techniques and data.
Industry best-practice standard diamond core sampling
methods and sample intervals are used.

Mineral tenement
and land tenure
status

Type, reference name/number, location and
ownership including agreements or material
issues with third parties such as joint ventures,
partnerships, overriding royalties, native title
interests, historical sites, wilderness or national
park and environmental settings.
The Alumbre project area is located at low attitude, in the
Department of La Libertad in northern Peru. There are no
historical sites, wilderness or national parks or environmental
issues. The current project area consist of group of concessions
with one concessions which is 100% owned by Promesa
Limited, plus one other adjoining concession which are subject
to option agreement, these include three concessions owned by
Oban S.A.C which allows 70% farm-in and includes an NSR
royalty and the Aurifera Chorobal concession owned by Minera
Fabricio S.A.C which allows 100% farm-in and includes an
NSR royalty.

The security of the tenure held at the time of
reporting along with any known impediments to
obtaining a licence to operate in the area.
Concessions and agreements are in good standing and the
company has social and government approvals in place to
explore.
Exploration done
by other parties

Acknowledgment and appraisal of exploration by
other parties.
The region was explored by Santa Cristina de Chorobal from
1993 to 1994. Newmont, from 1994 to 1996, undertook
regional exploration work.
Savage Resources, between 1996 and 1999 undertook
sampling, mapping, geophysics and drilling within some of the
current project area at Alumbre. Savage conducted a nine-hole
RC and RC/Diamond drill program and collected 573 rock
sampling program along channels of various lengths from 1 to
27m in length within part of the Alumbre area and the ad.
Historical Savage RC drill samples were composited up to 4m
and diamond drill holes were composited up to 2m. This
drilling produced anomalous results which were considered
worthy of follow up drilling by Savage. Location of these drill
holes have be verified as the collars are visible. Samples were
assayed by SGS laboratory; however this cannot be verified as
the original laboratory certificates are not available and were
pre-JORC.Promesa have undertaken confirmation field
sampling of Savage surface sampling which supports the
results obtained by Savage. Savage Resources was taken over
by Pasminco in 1999 who subsequently went into receivership
2001 and suspended work on the project area.
From 2001 to 2010 the area was not held by any party.
Alikante Mining Company 2010 acquired the Gaya 104
concession and released it to Kirio Mining S.A.C in 2011 who
then optioned it to Promesa in 2012. and acquired 100% of
the concession in August 2013.
Promesa has completed a Stage 1 drill program with results
released to the market in 1 July 2014.
Geology
Deposit type, geological setting and style of
mineralisation.
Mineralisation is hosted in several intrusive and subvolcanic
rock units. Disseminated and veinlet hosted porphyry copper
and molybdenum mineralisation has been observed

Drill hole
Information

A summary of all information material to the
understanding of the exploration results
including a tabulation of the following
information for all Material drill holes:
o
easting and northing of the drill hole collar.
o
elevation or RL (Reduced Level – elevation
above sea level in metres) of the drill hole
collar.
o
dip and azimuth of the hole.
o
down hole length and interception depth.
o
hole length.
Details of location and orientation of the drill holes mentioned
in this announcement are given in Appendix A of this
announcement (Table 1). Locations of the drill holes are also
marked on a map which places them in context with previously
released exploration results according to the JORC code (2004
edition and 2012).

If the exclusion of this information is justified on
the basis that the information is not Material
and this exclusion does not detract from the
understanding of the report, the Competent
Person should clearly explain why this is the
case.
Not applicable, the information has been provided above.
Data aggregation
methods

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.
Not applicable – no weight averages nor maximum/minimum
truncations were applied to this announcement.

Where aggregate intercepts incorporate short
lengths of high grade results and longer lengths
of low grade results, the procedure used for such
aggregation should be stated and some typical
examples of such aggregations should be shown
in detail.
Not applicable – no weight averages nor maximum/minimum
truncations were applied to this announcement

The assumptions used for any reporting of metal
equivalent values should be clearly stated.
Not applicable – equivalent values were used in this
announcement.
Relationship
between
mineralisation
widths and
intercept lengths

These relationships are particularly important in
the reporting of Exploration Results.

If the geometry of the mineralisation with
respect to the drill hole 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 (eg ‘down hole length, true width
not known’).
Where ever mineralisation is reported in this announcement,
clear reference to it being “down hole” width/thickness is
made.
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.
Appropriate maps are included in the body of the
announcement to show the location of the drill holes subject of
the announcement and their relationship to previously
announced geophysical and magnetic targets.
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.
The Company believes that the ASX announcement provides a
balanced report of stage 1 drill program.
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
The company has previously reported geochemical, geophysical
and geological results. This announcement discusses the Stage
2 drill holes.
As yet, no economic or extractive measurements such as bulk
sampling or metallurgical tests are appropriate at this stage of
exploration

large-scale step-out drilling).
Diagrams clearly highlighting the areas of possible
extensions, including the main geological
interpretations and future drilling areas, provided
this information is not commercially sensitive.
By Nature of early phase exploration further work is necessary
to better understand the mineralisation system that appears
characteristic of this area.
