High-Grade Copper Results Highlight Rapidly Growing Potential of Copper-Gold-Silver Project, Peru

Assays from earlier exploration work show Laconia’s newly optioned Fortuna prospect could help underpin a significant increase in Rasuhuilca’s resource inventory

Highlights:

  • Analysis of historical diamond core from the Fortuna Prospect at Rasuhuilca points to the existence of multiple lenses of copper mineralisation, with associated gold and silver

  • Diamond drillhole results include;

  • 5.75 m at 2.0 % Cu, 0.7 g/t Au and 97.31 g/t Ag from 31.15 m in SBD 01 2002; including 1 m at 7.2 % Cu, 2.45 g/t Au and 387.38 g/t Ag

  • 3.1 m at 2.27 % Cu, 3.43 g/t Au and 130.56 g/t Ag from 61.6 m in SBD 05 2002; including 0.5 m at 12.1 % Cu, 19.8 g/t Au and 708.75 g/t Ag and including 0.3 m at 2.72 % Cu, 1.09 g/t Au and 114.85 g/t Ag from 64.4 m

  • 6.3 m at 0.46 % Cu, 1.84 g/t Au and 28.28 g/t Ag from 2.2 m in SBD 02 2002; including

    • 1.6 m at 1.46 % Cu, 6.71 g/t Au and 72.0 g/t Ag
  • 12.6 m at 0.3 % Cu, 0.11 g/t Au and 43.93 g/t Ag from 27.9 m in SBD 05 2002; including 2.6 m at 0.9 % Cu, 0.19 g/t Au, 64.78 g/t Ag, 0.11 % Pb and 0.25 % Zn

  • Surface channel sample results include;

  • 0.8 m at 4.8 % Cu, 3.89 g/t Au and 251 g/t Ag from surface channel sample 29095

  • 1.4 m at 1.8 % Cu. 0.67 g/t Au and 51.3 g/t Ag from surface channel sample 29119

  • These results provide strong evidence that the significant copper-gold-silver mineralisation discovered at the Española 1 prospect1 at Rasuhuilca continues into the Fortuna Prospect

  • Results also support Laconia’s belief that the copper-gold-silver seen so far at Rasuhuilca sits as a cap over a major copper poryphyry system extending throughout

  • Laconia set to start next round of sampling at Fortuna, Española and other targets

  • Discussions with the local community on an access agreement are well advanced, paving the way for drilling to start at Rasuhuilca in the second half of calendar 2013

plus tesing the numerous new copper, gold, silver targets

Laconia Resources Limited (ASX: LCR) (“ Laconia ” or “ the Company ”) is pleased to announce that outstanding high grade copper-gold-silver values have been identified in historical diamond drilling and surface channel sampling at its newly optioned Fortuna Prospect within its flagship Rasuhuilca Project in Peru.

These results, while representing early-stage exploration work, are considered highly significant for two reasons. First, they suggest that the high-grade copper discovered at the adjacent Española prospect at Rasuhuilca continues into Fortuna, bringing substantial potential for further increases in the project’s total resource inventory.

Second, they support Laconia’s growing belief that the shallow high-grade copper-gold-silver mineralisation sits as a cap over an extensive copper porphyry system at Rasuhuilca. The copper in the cap, combined with knowledge of the geology, mineralisation and alteration, supports Laconia’s view that the porphyry may be an “El-Indio style” gold and copper porphyry system.

Fortuna, which is contained within a package of 11 tenements over which Laconia recently acquired an option (see ASX announcement dated March 26[th] , 2013) , is one of serveral targets at Rasuhuilca, including Española.

Outstanding exploration results have already been returned from each of these targets. Along with Fortuna, they will be the subject of further sampling work over coming months, with a view to undertaking an extensive drilling program across the project in the second half of this calendar year.

This program, which is subject to regulartory approval, will be aimed at both upgrading the existing JORC resource of 360,000t at 1.97 g/t gold and 179 g/t silver and growing it by including mineralisation from these other targets. Information regarding the existing JORC resource has been previously released by the Company.

Laconia Managing Director Ian Stuart said: “The Company is extremely encouraged by the identification of further strong copper-gold-silver grades from our flagship Peruvian project. Our knowledge of the wider Rasuhuilca Volcanic system continues to grow through the systematic processing and follow up of the excellent historical data. The presence of significant copper, in conjunction with the gold and silver epithermal veins already identified, adds significantly to the potential of the entire Rasuhuilca Project.

We are looking forward to starting our preliminary 2,000 m drilling program to upgrade and grow the Rasuhuilca resource.”

As part of this plan, the Company is working on permitting and community agreements utilising the Declaración de Impacto Ambiental (“DIA”) process of the Peruvian regulatory system, to obtain approval for the drilling program to commence.

Laconia believes that the presence of enargite, pyrite and marcasite as well as abundant high sulphidation silvergold quartz vein systems in pervasive quartz-alunite alteration, support the presence of an underlying porphyry system with potential for significant copper-gold mineralisation.

Fortuna Prospect Geology

The Fortuna Prospect lies about 600 m to the east of the Rasuhuilca Resource[1] in the Huaco Cucho No. 2 permit that is one of the 11 permits of the recently signed Option Agreement.[2] Mineralisation is hosted by a set of two parallel veins that trend east-west for at least 90 metres and dip steeply to the north, also intersecting the large regional Huaco Fault at the west end of the prospect. The veining is dominantly silicification with alunite alteration, and sulphides that include pyrite, marcasite, enargite, sphalerite and galena in order of decreasing abundance.

In addition to high grade copper, gold and silver values that are typical of the greater Rasuhuilca Project, Fortuna Prospect also contains some elevated zinc and lead. Copper is hosted in the mineral enargite, that was mined economically at the El Indio deposit in Chile. Zinc is hosted in the mineral sphalerite and the host for lead is galena. The polymetallic nature of mineralisation at Fortuna Prospect is indicative of metal transport under the highly mobile conditions generated in a porphyry environment.

The two veins at the Fortuna Prospect have been identified through surface channel sampling and diamond core drilling by Buenaventura between the years 1997 and 2002. During 2002, five diamond core holes were drilled at the Fortuna Prospect, and returned intersections confirming the main vein mapped at surface continues at depth.

The data from the drilling is well-documented and includes geology, sampling and QAQC data. Diamond core from the drill program may still exist, and discussions with Buenaventura are under way to acquire this historic core. The secondary parallel vein under cover of scree slope was discovered by the diamond drilling, and it lies about 20 metres to the north of the mapped Fortuna vein.

The surface geology of the Fortuna Prospect, surface channel sampling locations and diamond drillhole locations are shown in Figure 1. Significant intersections, calculated as weighted averages of down hole length to grade, of copper, gold and silver are annotated on the drill holes. True widths of the veins are not yet estimated, and all values presented in this release are down hole intersection lengths. Of particular interest are the unsampled

intervals in the drill-core. There are sections of core logged as containing disseminated pyrite, but which were not sampled in the original drill program. Further potential therefore exists for low-grade gold and silver mineralisation in zones of broad alteration with disseminated pyrite. Sampling will be undertaken if the core can be obtained, and any new drill campaign will sample the entire drilled interval.

An underground adit was developed at the 4760 level, to the western end of the Fortuna Prospect. The adit has driven about 100 metres across the Fortuna Lode sequence from north to south, At present geology and sampling data for the Fortuna adit development is being digitally captured from good quality PDF plans, validated and synthesised into the Company database. Once this process is completed, the results will be released.

Significant Diamond drilling results are summarised below (Detailed sample results are supplied in Appendix 1).

  • 5.75 m at 2.0 % Cu, 0.7 g/t Au and 97.31 g/t Ag from 31.15 m in drillhole SBD 01 2002; including 1 m at 7.2 % Cu, 2.45 g/t Au and 387.38 g/t Ag from 32 m

Exploration activities planned for the Fortuna Prospect include re-sampling of about 5 per cent of surface channel samples and sampling and mapping of the underground 4760 adit. If the drill core from the Buenaventura 2002 drill campaign can be acquired, infill sampling will be done. Drilling at Fortuna will be scheduled as soon as possible with a specific view to replicating the existing intersections to increase confidence in the existing results and providing infill drilling for the purposes of resource definition.

Duplicate sampling performed on the diamond core by Buenaventura, has produced some results with a large variance between the primary and duplicate sample. Plotting and compilation of the duplicate sampling has shown that the large variation is mostly restricted to the strongly mineralised samples, with low-grade and barren samples having good repeatability. The variation is random, with no bias for the primary or duplicate sample consistently producing a higher result. One example is sample 21101 from hole SDB-05-2002, shown with the duplicate sample in Table 1 below. This example shows the maximum material variance encountered in the duplicate study.

The copper mineralisation at Fortuna Prospect further adds to the Company’s confidence that there may be an El Indio-style enargite deposit in addition to a deeper mineralised porphyry system at Rasuhuilca. Figure 3 below outlines the exploration model currently being applied at Rasuhuilca. Copper at the Fortuna Prospect is interpreted to have been mobilised through the major regional Huaco Fault from a source at depth, to be deposited in the east-west trending Fortuna vein that intersects this major structure (see Figure 1 for the location of the Huaco Fault).

Exploration Results Summary

The overall geological setting is a volcanic system in the Andean highlands, that has an extensive area of alteration and High Sulphidation Epithermal mineralisation. There is potential for a Porphyry Copper-Gold body at depth. Results presented in this release are from 35 surface channel samples and five HQ diamond core drill holes conducted by Buenaventura between 1997 and 2002. Drill spacing is about 25 metres apart with one hole

Sampling of the diamond core was done at lengths of 0.15 – 2 metres, as contiguous runs through zones of logged alteration (targeting silicification and breccia). The sample was halved diamond core, that was cut so as to equally divide significant structures in the rock. Standards, duplicates and triplicates were submitted routinely with surface channel sample batches, and diamond core batches.

Sample preparation techniques used at the laboratory are not known, but the analysis method used was Atomic Absorption Spectrometry (AAS) with Fire Assay on 50 gram aliquots to 2 ppb detection limits. AAS was also used for silver, or by Inductively Coupled Plasma – Mass Spectrometry (ICP-MS) + 9 elements (Cu, Pb, Zn, Mo, As, Sb, Bi, Hg, Te). Sample chain of custody documentation was not done, or not acquired in the data package.

Geological mapping and drill interpretation by Buenaventura and Laconia geologists has been used to compile the information in this release. Sample results in the diamond core were composited based on a nominal cut-off of greater than 1 g/t gold, or 60 g/t silver or 0.1 % copper, and then calculated as a weighted average of sample length versus sample grade, divided by the entire composite length.

Rasuhuilca Project background

Laconia completed the acquisition of the Rasuhuilca Project[3] in the Southern Andes of Peru in June 2012. Rasuhuilca is an advanced, high grade gold and silver project which contains existing development levels and cross-cuts. The flagship project represents outstanding development potential in the current high gold and silver price environment. The Project currently has an Inferred Resource estimate of 360,000 t @ 1.97 g/t gold and 179 g/t silver (at a 2.5 g/t gold-equivalent cut-off). [All cut-offs based on an Xg/t Au Eq are conceptual in nature

only. There has been insufficient metallurgical testwork to date to determine eventual metallurgical recoveries and it is uncertain that the conceptual cut-offs used will be appropriate following further metallurgical testwork.]

The Company recently reported five additional Exploration Targets of 365,000 t to 792,000 t grading 2.4-3.1 g/t Au and 84.9-122.4 g/t Ag at vein systems within Rasuhuilca adding significant potential to the project (see Figure 4). [The potential quantity and grade of the Exploration Targets is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Refer ASX release 4 February 2013.] Previous explorers were aware of the potential scale and size of the Rasuhuilca Volcanic system and its Porphyry Copper-Gold potential due to its geological similarities to the El-Indio deposit in Peru ( Caddy, 1996. ). El Indio contained some 23.2 Mt at 6.6 g/t Au, 50 g/t Ag and 4% Cu including a bonanza gold zone of 200 kt at 209 g/t Au ( Sillitoe, 1999) . The Company has consequently expanded its compilation of historical data to include any available copper sampling undertaken across the Project licences with the view that the Project contains a buried and fully intact Epithermal/Porphyry system. Figure 3 shows a schematic of the exploration model now being used at Rasuhuilca by Laconia. It contains examples of known vein and breccia systems on the Project and the current understanding of how they relate to the Epithermal/Porphyry model.

Laconia continues the process of identifying and verifying all existing and available data from sampling conducted by the Cominco and Buenaventura companies and will continue with its process of re-sampling to “twin” existing surface and underground samples and drillholes. New sampling work will be undertaken and together the data will provide increased confidence for upgrading resource estimates.

Diamond Drilling Program to commence on permit approval

Laconia plans to commence its first phase of diamond drilling at the Rasuhuilca Project as soon as exploration permitting approval is received. The process of formal approval to undertake exploration drilling in Peru follows the completion of a DIA. The DIA includes environmental considerations and community consultation and approval.

Upon receipt of approvals, Laconia will undertake an initial phase of diamond drilling consisting of 850m. This initial round of drilling will be aimed at providing infill information between levels, to upgrade the JORC resource to Indicated category. A further minimum of 1,150 metres (for a total program of 2,000 metres) will also be planned to test the new targets recently highlighted through gold and silver targeting, plus the new copper targets. The Company believes significant potential exists to grow the resource base outside of its current boundaries through further detailed exploration.

As a matter of priority, exploration drilling and additional sampling activities are planned on the Rasuhuilca vein and its extensions to the west, namely the Condor zone, and the Hyallatas Prospect. Exploration sampling and drilling on the Olga, Española 1 and Marcelita prospects is scheduled to follow the initial resource extension work. All exploration field work and timeframes are dependent on the timing of community and government approvals.

Option Deal to Acquire Indirect 80% Interest in Exploration Licenses Adjacent to Company’s Rasuhuilca Project

On 26 March 2013, Laconia announced that it had agreed a seven year option to acquire an indirect 80% interest over 11 additional exploration licences bordering the Company’s Rasuhuilca Project, including the Fortuna Prospect.[4]

Criteria JORC Explanation Remarks
Sampling
Techniques
Nature and quality of sampling (eg 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.
Cut surface channel samples – 30 cm width.
Cut underground channel samples – 30 cm width.
Diamond core samples collected by Buenaventura were of half HQ
core, with the sample cut so as to equally divide structures. Sample
lengths ranged from 0.15 m to 2 m. Sample intervals were matched
to geological boundaries.
Include reference to measures taken to
ensure sample representivity and the
appropriate
calibration
of
any
measurement tools or systems used.
Buenaventura used a sample size of 3.5 kg per metre of channel
sampling. They routinely submitted duplicate and triplicate samples.
The employed umpire laboratories to check their results with
triplicate samples, as well as re‐submitting pulps.
Aspects

to produce a 30 g charge for fire assay’).
In other cases more explanation may be
required, such as where there is coarse

has
inherent
sampling
problems. Unusual commodities or
mineralisation types (eg submarine
nodules) may warrant disclosure of
detailed information.
Channel samples were collected using best method (ie. cut with a
rock saw).
Duplicates and triplicates of channel samples were obtained through
re‐cutting a second or third sample in the same location. Channel
samples were not split for the purposes of creating duplicates or
triplicates.
Diamond core samples were HQ diameter, and were cut in half using
a core saw, dividing geological structures equally where possible.
Some samples demonstrated a significant variance when compared
to duplicate samples, but this affect was observed to be minor, with
most samples showing good repeatability.
Sample preparation techniques are not known.
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).
Drill Sample
Recovery
Method of recording and assessing core
and chip sample recoveries and results
assessed.
Drill core recovery was recorded for every hole through routine
monitoring of drill rod depth and recovered core. Recoveries for
each hole were graphically plotted and show total recovery better
than 97%, with greater than 95% recovery through zones of
structural complexity.
Measures taken to maximise sample
recovery and ensure representative
nature of the samples.
Supervision of the diamond drilling by Buenaventura geologists
ensured sample recovery was good, and that samples were
representative without contamination issues.
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
No studies are known to have been completed on sample bias.
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.
Surface and underground channel samples were plotted onto
geological maps that were created using a consistent legend.
No geotechnical logs are available for channel samples or diamond
drill core.
Geological logging for diamond core includes a descriptive log with
some quantitative logging of sulphides and alteration, in addition to
plottingof assays and thegeologyas agraphic log.
Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel, etc) photography.
Logging is qualitative, with the exception of some quantitative
logging of sulphide and alteration content.
No routine photography of channel sampling is available. Routine
photography of the core was done, but this photography was not
acquired in the datapackage.
The total length and percentage of the
relevant intersections logged
100% of surface channel samples presented in this release have
mapping that can be applied as logging.
100% of diamond core samples can be correlated to graphic logs of
the diamond drill hole.
Sub‐sampling
Techniques and
Sample Preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
Drill core samples were half HQ core, where the core was cut to
equallydivide significant structures in the rock.
If
non‐core,
whether
riffled,
tube
sampled, rotary split, etc and whether
sampled wet or dry.
Surface channel samples were not split during any part of the
process. They represent complete channels. Water was used during
cutting,but then a drysample collected usinga hammer and maul.
For all sample types, the nature, quality
and appropriateness of the sample
preparation technique.
Details on laboratory preparation of samples are not known.
Accuracy of results is implied through performance of duplicate and
triplicate samples and utilisation of umpire laboratories.
Diamond core samples were halved to ensure equal division of
significant structures, and due to the large diameter of core (HQ) is
thought to be representative.
Quality control procedures adopted for
all sub‐sampling stages to maximise
representivity of samples.
For both channel sampling, and diamond drill core sampling,
standards and blanks were interleaved with the routine samples,
every 20thsample.
For the channel sampling, duplicates were cut for every 20thsample.
Triplicates were cut and sent to an umpire lab, at a frequency of
about 3%.
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.
Duplicates and triplicates were collected through cutting another
channel sample, not splitting the existing channel sample.
Duplicate samples were submitted for a few samples and
composited intervals in the diamond core. There was significant
variation between the primary and duplicate sample in the
mineralised material. Repeatability of results in the barren rock was
good.
5% of total sample numbers were submitted as duplicates, and 2.5%
were submitted as triplicates.

17

==> picture [596 x 39] intentionally omitted <==

Umpire laboratory re‐assaying of 8 diamond core pulp samples show
good repeatability of results. The original laboratory was CIMM
Laboratories,and the umpire laboratorywas ALS Chemex.
Whether sample sizes are appropriate to
the grain size of the material being
sampled
Channel sample sizes were appropriate, as shown by good
correlation between primary, duplicate and triplicate results.
Diamond core samples were half HQ core, which is a large diameter
core for exploration drilling. Some bias may be introduced during
half coring, due to the presence of brecciation, which is inherently
erratic ingrade.
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.
For channel samples and diamond core samples, gold (Au) was
analysed by AAS with Fire Assay checks on 50 g aliquots to 2 ppb
detection limits and AAS was used for Silver (Ag). ICP‐MS was used
for the other elements (Cu, Pb, Zn, Mo, As, Sb, Bi, Hg, Te). Digestion
method is not known and so completeness of technique is unknown.
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 or other unusual analysis methods were
employed.
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.
For both channel sampling, and diamond drill core sampling,
standards and blanks were interleaved with the routine samples,
every 20thsample.
For the channel sampling, duplicates were cut for every 20thsample.
Triplicates were cut and sent to an umpire laboratory (, at a
frequencyof about 3%.
Verification of
Sampling and
Assaying
The
verification
of
significant
intersections by either independent or
alternative company personnel.
No intersection verification at Fortuna prospect has been done,
though Buenaventura repeating Cominco sampling at other
prospects, and Cambridge Mineral Resources repeated Cominco and
Buenaventura sampling at a later date. Laconia repeated Cominco
and Cambridge Mineral Resources sampling (33 samples) in the
Rasuhuilca underground development, and the results showed the
original sampling was repeatable.
Geostatistical plots from the Rasuhuilca underground samples show
excellent correlation between Cominco and Cambridge Mineral
Resources for gold and silver. Buenaventura results were
comparable for silver, but appear to have understated gold by a
factor of 63%. The reason for this is not fully understood, but the
results were not used for the resource estimation because of this.
The Buenaventura results are considered suitable for exploration
targeting as there is a potential upside due to the finding that the
error was understatingthegold content.
The use of twinned holes. No twinned holes have been used to verify sampling and assaying.
Documentation of primary data, data
entry procedures, data verification, data
storage
(physical
and
electronic)
protocols.
Data has been compiled from good quality paper plans and digitally
compiled at a later date.
The data has been assimilated into the Company SQL database, and
exported into Microsoft Access, after compilation and validation in
Surpac and Mapinfo Software and checks against topography and
thequalityof repeated sample locations.
Discuss any adjustment to assay data. There was re‐calculation of assays reported as oz/t to g/t. The
calculation was based on the imperial oz (28.34 grams to an ounce),
rather than the troyounce(31.10grams to an ounce).
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.
Cominco established professionally surveyed trigonometric points
across the Rasuhuilca project. From these survey points, surface
mapping and sampling was spatially referenced. Underground
development at Rasuhuilca was surveyed by Cominco, with
permanent survey points established in the adits.
Followingworkers(Buenaventura,Cambridge Mineral Resources,

18

Laconia Resources) utilised these survey points for spatial location of
their work. Buenaventura used a company employed surveyor.
Only the Rasuhuilca underground development sampling and
surface samplinginforms a resource estimation.
Specification of the grid system used. All data was collected as, and remain in, PSAD56, Zone 18 South,
EPSG 24878.
Quality and adequacy of topographic
control.
Topographic surface uses 10 metre contours that have excellent
correlation toground features.
Data Spacing and
Distribution
Data spacing for reporting of Exploration
Results.
Surface channel samples are collected perpendicular to the vein
walls, at spacings of 5 to 30 metres apart.
Diamond drill core samples are collected over contiguous intervals of
alteration as per logging. There are lengths of diamond core not
sampled. Some sampled intervals were re‐sampled as composites,
or as single duplicate samples.
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.
No Mineral Resource or Ore Reserve calculations have been
reported on the Fortuna Deposit.
Whether sample compositing has been
applied.
Sample compositing was performed for reporting of diamond drill
core results, based on a weighted average as a function of sample
length versus grade.
No compositingwas done for surface channel samples.
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.
Surface channel samples were collected perpendicular to vein walls,
or across zones of alteration, and are representative of the
mineralisation controls.
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.
The drilling was oriented to intersect the vein at close to 90 degrees
at depth, minimising apparent thicknesses. Sample core was halved
to equally divide the mineralised structures.
Some sampling bias may have been caused by brecciation, where
the erratic nature of mineralisation makes it impossible to accurately
halve the structure.
Sample security The measures taken to ensure sample
security.
No chain of custody was documented for Buenaventura sampling.
Audits or reviews The results of any audits or reviews of
sampling techniques and data.
At a project scale, numerous repeat sampling exercises validate the
sampling of previous workers.
A review of duplicate or composited duplicate interval samples for
the Fortuna diamond core reveal a large magnitude of difference in
the mineralised samples, but not in the barren material. There is an
example of the largest material difference between the primary and
duplicate sampling provided in the bodyof this release.

Other Parties
Acknowledgement and appraisal of
exploration by other parties.
The project area has previously been explored by COMINCO el Peru
between 1985 and 1987, by Compania de Minas Buenaventura SAA
from 1996 to 2003. Echo Bay undertook exploration in a JV
partnership with Buenaventura between 1996 and 1999.
Cambridge Mineral Resources (CMR) acquired the project in 2005
and started development and small‐scale mining at the Marcelita 2
vein. Theymoved focus to the Rasuhuilca vein in September 2006.
Geology Deposit type, geological setting and style
of mineralisation.
High sulphidation epithermal gold‐silver veining and alteration halos,
with localised enargite‐rich breccias along fault controlled paths.

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:

easting and northing of the
drill hole collar

elevation or RL (Reduced Level
– elevation above sea level in
metres) of the drill hole collar

dip and azimuth of the hole

down
hole
length
and
interception depth
• hole length.
All tabulated exploration results are included in the release in
appendix 1.
Intercept lengths from diamond drilling are presented as down hole
lengths, not true lengths, and this is stated in the release.
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.
No information is excluded.
Data Aggregate
Methods
In
reporting
Exploration
Results,
weighting
averaging
techniques,
maximum
and/or
minimum
grade
truncations (eg cutting of high grades)
and cut‐off grades are usually Material
and should be stated.
Weighting is calculated as a function of each sample length
multiplied by each grade, with the summed product divided by the
total sample length, to present composited intervals.
No top or bottom cut was applied.
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.
Where intercepts are reported as longer lengths of lower grade, it is
clearly stated that the higher incepts within are part of the lower‐
grade intercept, not in addition to the low grade intercept.
The assumptions used for any reporting
of metal equivalent values should be
clearly stated.
No metal equivalents are used for the exploration results at Fortuna
Prospect.
Relationship
between
mineralisation
widths and intercept
lengths
These relationships are particularly
important in the reporting of Exploration
Results.
Surface channel samples reflect vein true widths as they are cut
perpendicular to the vein walls.
Diamond drill sample intercepts are reported as down hole widths.
If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.
Mineralisation geometry is assumed to be vein controlled and sheet‐
like or tabular, dipping steeply to the north. The drill holes were
angled to intersect the vein as close to 90 degrees as possible. As
further work is required to fully define the vein geometries, all
diamond drill results are reported as down hole lengths, not true
lengths.
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’). _
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 provided that show all surface samples and the
diamond drill hole traces in plan view, plus a cross section is provided
with the intercept locations and known geology.
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.
All exploration results are presented in the Appendix 1, regardless of
grade.
Other substantive
exploration data
Other exploration data, if meaningful and
material, should be reported including
(but not limited to):
geological
observations;
geological
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.
Discussion of the Fortuna Prospect geology is included in the release.
To date no economic or extractive measures such as bulk samples,
metallurgical testing, bulk density, groundwater, geotechnical or rock
samples have been done.
Mineral species hosting base metals are identified in the release.
Further Work The nature and scale of planned further
work (eg tests for lateral extensions or
depth extensions or large‐scale step‐out
_drilling). _
Drill testing is identified as future planned work. At present the
amount and location of planned drill holes has not been identified.
Diagrams clearly highlighting the areas of
possible extensions, including the main
geological interpretations and future
drilling areas, provided this information is
not commercially sensitive.
Possible extensions are indicated on the plan and cross section
