Mineral Resource estimate for the MCB Copper-Gold Project

The MCB Mineral Resource has been defined as a body of copper and gold mineralisation which is predominantly above 0.2% copper on average. The boundaries of this mineralisation are parallel to the dominant geological trends and the genetically related intrusive tonalite bodies that have been interpreted at MCB.

The 0.2% lower limit is also broadly in line with the expected economic limits of the likely mining and processing options considered for the MCB deposit. Therefore, a preferred lower cut-off grade of 0.2% copper was applied to the reporting of the Mineral Resource estimate.

As part of the future work program a mine plan will be developed that focuses on the early development of the central copper-gold higher-grade core to maximise returns in the early years of production. These studies will consider copper and gold mineralisation at higher cut-off grades ranging up to 0.5% copper as defined in tables 2 to 4 below.

Future Work Program

The MCB Mineral Resource estimate has already defined a large deposit, with its total tonnage increasing to over 300Mt at lower cut-off grades. In addition, there appears to be significant scope for further discoveries and extensions to the currently defined Mineral Resource at MCB.

The exploration program for the 3[rd] renewal of EP-003-2006-CAR aims to advance the project to a Scoping Study phase while gathering information to support a Definitive Feasibility Study. Information gathered will support further ore body modeling and development of an underground mine plan, metallurgical testing, sterilization drilling, flotation test work, development of a conceptual hydrological model, infrastructure layouts, high-level financial model along with an updated Mineral Resource. Depending on the outcome of the scoping study, preparation/planning will occur for the delivery of a Definitive Feasibility Study (DFS) and therefore the Declaration of Mining Project Feasibility (DMPF) pursuant to Philippine DENR Administrative Order No. 201021.

Property area and location

The MCB Project is located in Barangay Balatoc, Municipality of Pasil, Province of Kalinga (Figure 1). From Manila, the best route to reach the project site is via the Cagayan Valley road going to the City of Tabuk, hence to the municipality of Pasil. Distance from Tabuk to Pasil is approximately 60 km via the Tabuk-LubuaganBontoc SONA Highway, which is a travel time of approximately 3 hours utilizing four-wheel drive vehicles. From Lubuagan junction, access is through approximately 24 km of rough dirt road.

==> picture [484 x 349] intentionally omitted <==

Tabuk can be reached from Manila via Tuguegarao City, which has daily flights from Manila with travel time of about 50 minutes. Tuguegarao is located inland along the Cagayan River Valley. Travel by public utility bus is also available from Manila to Tuguegarao and takes about 12 hours.

Settlements are generally small, compact, and occupy limited area and are located in the main Barangay of Balatoc. Most of the areas within and surrounding the MCB Project tenement are natural land covers consisting of grassland with sporadic pine trees.

The Property is made up of a single Exploration Tenement with the permit number of EP-003-2006-CAR. The underlying permit is in the name of the Philippine-registered corporation Makilala Mining Company Inc (MMCI) which is 100% owned by a private Company Makilala Holdings Ltd.

The Exploration Tenement was originally approved in 2006 and has had its 3rd renewal approved by the MGB on November 24th 2020.

Geology and Geological Interpretation

The geological interpretations and technical information that have contributed to the maiden Mineral Resource estimate at MCB are based largely on surface mapping, analysis of 46 diamond drill holes (25,547m) completed by Freeport McMoRan from 2006 to 2013, and validation and analysis of the drill hole information (Figure 2).

The geological setting for the MCB copper-gold mineralisation is typical of a porphyry copper + gold + moly deposit. The mineralisation and associated alteration exist across the contact between a genetically related intrusive body (tonalite) and the surrounding host rock material. In most cases the surrounding host rock is an older mafic volcanic rock (see Figures 3 and 4).

==> picture [483 x 418] intentionally omitted <==

The location and trend of the copper-gold mineralisation is influenced by two dominant structural trends that exist at MCB. The broad fabric and trend of the intrusive bodies and associated alteration extends in a northeast direction, or at approximately 50 degrees with a near to vertical dip. This orientation is also parallel to some major faulting.

Broad copper-gold domains which defined the Mineral Resource estimate at MCB have been defined based on a combination of continuous zones of copper and gold mineralization which corresponds with alteration features and the controlling geological host rocks and structures.

There is also evidence at MCB for epithermal vein deposit types which exist within close proximity to the largescale porphyry copper-gold mineralisation. At this stage the only deposit type that is defined in the Mineral Resource estimate for MCB is a porphyry copper-gold style.

MCG Block Model

All drilling information was assessed with regard to the potential of defining a new Mineral Resource estimate for MCB. There are three separate locations that appear to have significant copper-gold mineralization. Only one of these has currently been considered to fulfill all of the required criteria to be classified as a Mineral Resource under the JORC Code (2012) (Type 1HG and Type3LG). However, there are two locations with significant assay results which appear to be on the edge of a new zone of significant copper-gold mineralization (Block 3 LG, Block 1 LG) which could be ultimately be converted into additional copper-gold Mineral Resource with further successful drill hole information at these locations (Figure 5).

The following figures are presented to represent some of the details associated with the block model which was completed to estimate the copper-gold Mineral Resource at MCB. Figures 5 is an oblique view of the full block model with the various domains identified for reference. Figure 6 is a plan view image at the 700m level (close to the central position of the block model) which can be used to reference the location of a series of representative cross section view diagrams. The cross-sections are cut at an angle which is approximately perpendicular to the interpreted copper-gold mineralization for a more representative view of the true thickness of the copper-gold mineralization at MCB. Each cross section identifies the spatial distribution of the copper mineralisation in the block model relative to the drill hole data.

Drilling Techniques

Exploration diamond drilling was contracted to DrillCorp Philippines, Inc. (DCP), between December 2006 and July 2013, comprising 46 drill holes with an accumulative meterage of 25,480.55 metres. Four prospect areas were drilled; Thirty holes (MCB-001 to MCB-030) were collared at MCB (Area 1), located north of Pasil River (Area 1), and the adjoining West MCB (Area 2), for a total of 15,237.05 meters. Sixteen holes (CBG-001 to CBG-016) were drilled at the Caigutan (Area 3) and Binasalan (Area 4), located south of Pasil River, for a total of 10,243.50 meters (Figure 6).

All of the diamond drilling utilised a triple tube core barrel for the entire length to ensure maximum sample recovery. On average the size of the drill core captured was 13% for PQ size, 44% for HQ size and 43% for NQ size.

Sampling and Sub-Sampling Techniques

Samples were collected from diamond core drilled from the surface. All drill core was generally sampled on 2.00m intervals. In cases where geological and mineralogical characteristics change, the sample length was reduced to best fit the geological contact, with a minimum sample size of one meter observed. Sampling typically commenced after the overburden horizon depth was exceeded.

The following sub sampling and sample preparations were followed for all the diamond drilling at MCB.

A. Drying and Weighing: Samples were weighed, dried in an oven at 105 Celsius for 6 to 8 hours. For samples with high clay content, drying time is extended up to 16 hours. After drying, samples were weighed again to calculate the moisture content.

  • B. Crushing: Samples were then primary crushed to a size of <4mm. Using a Boyd crusher, secondary crushing produces <2mm product size. The 1kg crushed material is retained for final preparation.

  • C. Pulverizing: The 1kg split is pulverized to -200 mesh with a grinding time of 4 to 6 minutes for 1kg ground samples.

  • D. Splitting: 1kg sample is split successively to obtain 4 samples of 250 grams each. Out of the four pulp samples, one sample is dispatched to the laboratory for analysis. Remaining pulp samples were retained for later use as duplicate assays and inter-laboratory checks.

Sample Analysis Method

After sample preparation, all samples were sent for analysis at the Intertek laboratory in Manila. Intertek is an internationally recognised and ISO/IEC 17025:2005 & ISO/IEC 17020:2004 certified independent laboratory.

Copper (Cu) values were analysed by means of geochemical digest using perchloric/hydrochloric acids. Elements determined by AAS finish. Samples were fire assayed for gold (Au) using a 50-gram charge, with a detection limit of 0.005 ppm.

QA/QC standards and blanks making up just under 10% of all samples sent to the laboratory were routinely submitted to check the quality of the assay data which makes up the exploration information for the MCB Mineral Resource estimate. The QA/QC data has been reviewed by the author from the original assay laboratory reports with no systematic bias or random errors identified.

Estimation Methodology

Based on the general dimensions of the interpreted ore domains, and the likely mining method, a parent cell block size of 10m x 10m x 10m was chosen for the Mineral Resource estimate.

Basic statistical information and variogram analysis was reviewed for both copper and gold within the various defined high grade and low-grade domains. The interpreted domains of Type 1HG and Type 3LG were the only 2 domains that were considered to have sufficient data distributed well enough to provide a basis for the use of a more sophisticated interpolation method such as Ordinary Kriging. The parameters for the Ordinary Kriging were based on an analysis of the variograms for each domain. The variograms (defined within the Leapfrog Edge software package) were located along the plane of the interpreted controlling geological trend which is striking at 50 degrees at a near vertical dip.

Where the data was generally insufficient to create meaningful variograms, the inverse distance method of interpolation was used. These domains were all classified as Inferred due to the general lack of drilling information to apply a greater level of confidence in their interpolation results.

A broad review of the statistics for each domain did not identify significant high value outliers that are considered likely to result in an overestimated either locally or globally to the grade distribution within the block model. Therefore, no top cut was applied to the Mineral Resource estimate.

Classification Criteria

Based on a combination of the changes to the geology and the variogram analysis, it was considered appropriate to apply a maximum distance of 200m to both the major and semi-major axis positions and 100m in the minor direction for the limits of the Indicated Mineral Resource (first pass), with a minimum number of samples at 4 and maximum number of samples at 20.

The Inferred Mineral Resource (second pass) was extended for twice this distance pushing the limits within the defined domains to 400m x 400m x 200m, with a minimum of 2 samples and maximum of 15 samples defined for the second pass interpolation.

Cut-off Grade

A lower cut-off grade of 0.2% copper has been used as the preferred lower cut-off grade for the reported Mineral Resource estimate, which is considered appropriate based on the geological continuity associated with copper mineralisation above 0.2% copper in addition to a broad economic cut-off point based on a US$3.0/lb copper price.

Metallurgical and Mining Factors

Information pertaining to the historical mining and processing of a similar copper-gold deposit on the adjacent Batong Buhay Property provides for a basic set of assumptions that have been used for the reported Mineral Resource estimate at MCB. The information pertaining to the Batong Buhay deposit that are relevant to this assessment include the ability to use a large-scale block caving method, in addition to producing a copper-gold concentrate with reported recoveries in excess of 80%.

ASX RELEASE | PAGE 16

==> picture [575 x 106] intentionally omitted <==

Benchmark mining costs of US$10/t to US$7/t and processing costs of US$7/t to US$4/t respectively for a medium sized (5Mt to 10Mt per annum) underground block caving mining method and processing using floatation to produce a copper-gold concentrate have been assumed where applicable for the Mineral Resource estimate. This cost range estimate matches closely with a broad geological cut-off grade of between 0.15% copper and 0.25% copper (at a Copper Price of US$3.0/lb).

Transaction Completion Schedule

The Notice of Annual General Meeting has been distributed to shareholders, with the meeting to be held at 11am (WST) January 29[th] 2021, where key resolutions will be considered which will allow completion of the acquisition of Anleck Limited shortly thereafter.

This announcement has been authorized by the Board of Directors of Celsius Resources Limited.

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.
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
(eg ‘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.
 Samples were collected from diamond core drilled from the surface. All
drill core was generally sampled on 2-meter intervals. In cases where
geological and mineralogical characteristics change, sample length
was not less than 1 meter.
 Magnetic susceptibility measurement were taken using SAIC
Exploranium Kappameter KT-9 to determine the amount of magnetite
present in copper.
 Thermo Niton XLT XRF Analyzer was employed in determining the
elements present, in ppm, such as Cu, Pb, Zn, As and Mo.
 Core samples cut into half using diamond core saw following the
cutting lines marked by the Geologist. Split cores returned to its
respective core tray.
 Samples were shipped to Intertek Testing Services which is an external
laboratory located in Manila, Philippines.
 Crushed samples were fire assayed for gold (Au) using a 50-gram
charge, with a detection limit of 0.005 ppm. Gold values greater than
50 ppm were determined by gravimetric fire assay.
 Copper (Cu) values were assayed using geochemical digest using

A total of 46 diamond drill holes were completed from December 2006
to July 2013 for an aggregate meterage of 25,480.55.

The core drilling uses triple-tube core barrel from collar to the end of
hole to ensure high core recovery. The size of the drill hole core
samples is summarized as follows:
o
PQ sized drill core with a core diameter of 83.1 mm, for a total of
3,234.20 meters, which covers 13% out of the cumulative
meterage,
o
HQ sized drill core with a core diameter of 61.1mm, for a total of
11,308.44 meters, which covers 44%, of the cumulative meterage,
and;
o
NQ sized drill core with a core diameter of 45.1 mm, for a total of
10,937.91 meters, which covers 43%, of the cumulative meterage.

Core recovery has been recorded for every interval as part of the routine
geomechanical logging, which is undertaken at the drill site after the core
is pulled-out of the inner tube barrel.

Recovered core lengths on average were measured to be 97% for the total
length of the recorded drilling length, indicating a high recovery and
minimal lost core.

All drilling activities were supervised by company Geologists. Trained Core
house Technician was responsible for the core recovery determination.

Core was arranged to fit the breakages, before the actual core length from
the start to the end of the drill run was measured. Percent recovery was
calculated from dividing the measured core length over the total drill run
multiplied by 100.

There was no observable bias or specific geological position where there
was repeated lower than average core recovery.
Logging Whether core and chip samples
have been geologically and
geotechnically logged to a level of

Geologists were tasked to oversee the daily quick log report down to
sampling. Daily quick log form was completed to identify the geological
details such as lithology, alteration and mineralization with corresponding
percentage estimate of Cu minerals and Cu grade, using an established
geological codes.

Detailed logging proceeds describing geological characteristics present in
the core, i.e. lithology, alteration, mineralogy, structures, etc.

Logging has been conducted in a qualitative and quantitative manner -
detailed description of geological characteristics, notations for the drilling
log progress and percentage estimates on mineralogy present.

Core photography was undertaken after completing the geomechanical
logging.

All data reference points and maps for the Makilala database, including

Compass measurements taken by Geologists were used to establish the
dip and azimuth of the collar hole as part of their initial collar surveys. Drill
collar locations were positioned using a handheld Garmin GPS unit, set to
UTM WGS 84 Zone 51N coordinate reference system, with an accuracy
expected to be within 2 meters. Downhole surveys were also completed
using a single shot camera at 100m intervals.

Collar surveys were then logged into the master MS Excel spreadsheet as

The broad drilling pattern is at 100m spacing for a series of drill holes
which are oriented in a north-west direction and dipping at predominantly
at 60 degrees. These drill holes are augmented by some drill holes which
have a west-north-west orientation or a north-east orientation or are
vertical. (see figures 2 to 4 – Drill Hole Locations and Cross Sections).

Drill holes were distributed on eight grid lines, from the prospects area,
giving coverage of 1,000 meters from east to west.

The drill hole spacing where significant copper-gold mineralisation has
been identified is sufficient to determine the geology and grade continuity
of the area, as well as the ore body and mineralization extents.

If the relationship between the

In the resource estimation, drill hole assays were composited to 2 meters
downhole intervals.

The dominant trend of the tonalite intrusion, which is directly related to the
copper-gold mineralisation has an overall strike of 50 degrees and a near
to vertical dip. Drill hole directions vary relative to this dominant
orientation, with some more optimal drill holes dipping at 60 degrees
towards 320 degrees. There are a number of vertical drill holes which are
not optimal for assessing the geological contacts or grade distribution,
however, in most cases these drill holes are also close to other drill holes
which are dipping across the mineralised domains, typically at 60 degrees.

Geology Deposit type, geological setting
and style of mineralisation.

The geological setting for theMaalinao-Caigutan-Biyog (MCB)copper-
gold mineralisation is typical of a porphyry copper + gold + moly deposit as
commonly defined in many academic papers (Hedenquist and Lowernstern,
1994; Sillitoe, R. H., 2010. Corbett and Leach, 1997). The mineralisation
and associated alteration exist across the contact between the genetically
related intrusive body (tonalite) and the surrounding host rock material. In
most cases the surrounding host rock is a mafic volcanic, however, in some
instances the older (not genetically related to copper-gold mineralisation)
intrusive bodies also exists in contact with the younger intrusive resulting in
broad sections of mineralisation and alteration within a series of intrusive
bodies.

There is also evidence at MCB for epithermal vein deposit types which exist
within close proximity to the large-scale porphyry copper-gold
mineralisation. At this stage only the deposit type that is identified from the
drilling information for MCB is a porphyry copper-gold style.

Basalt lava flows make up the majority of the host rocks in the tenement
area, which is part of the oldest exposed unit, Basement Complex. This
Cretaceous-Paleogene Metavolcanics has been intruded by quartz diorite
complex, which in Kalinga, ranges in composition from gabbro to tonalite.

A later stage Tonalite intrusion exists throughout the project area and is
interpreted to be genetically related to the copper-gold mineralisation at
MCB deposit.

A dacite flow and dacitic pyroclastic blankets the older basalt host rock and
tonalitic intrusive rocks.

There are four types of ore mineralization that were emphasized in the
project:
o
Type 1- Early high-grade porphyry Cu-Au mineralization,
hosted both in tonalite and basalt.
o
Type 2- Mix of high-grade porphyry Cu-Au (Type 1) and
high-sulphidation mineralization (Type 4). Hosted in basalt
and tonalites, but with strong Type 1 mineralization that was
partially overprinted by ore Type 4.
o
Type 3- Medium grade porphyry-copper
o
Type 4- High-sulphidation epithermal mineralization
(See figures 2 to 4 for representative Cross Sections of the Geology and its
relationship to the copper-gold mineralisation at the MCB Deposit ).

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.
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.
The assumptions used for any
reporting of metal equivalent
values should be clearly stated.

Significant intersections are reported in Appendix 1 and are aggregated
relative to broad mineralised interval which correspond with a definable and
continuous zone of copper-gold mineralisation, nominally above a grade of
0.2% copper on its margins. The intervals have been reported as weighted
average totals. Internal to the broader mineralisation that has been
reported, there are some internal higher-grade copper-gold assay results
reported (nominally above 0.5% copper) which are interpreted to exist as a
continuous domain of higher grade copper-gold mineralisation. These
sections have also been reported as weighted average totals.

Only individual weighted average assay results have been reported and no
metal equivalent values have been reported.

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’).

There are a number of drilling orientations, but generally drill holes were
designed in a rough grid pattern on lines oriented N30W-S30E spaced at
100 to 200 meters apart, with an inclination of -60 degrees. For the drilling
which is at an angle of -60 degrees, there is a relative angle against the
contact of the near to vertical intrusive Tonalite and associated copper-gold
mineralisation of approximately 30 degrees. In this case, the estimated true
widths of the copper-gold mineralisation is approximately half of the
reported down hole length.

In some instances, there are vertical drill holes which are still useful in
defining the extent of the copper-gold mineralisation, but at a relatively poor
angle to define the distribution of the copper-gold mineralisation due to
being sub-parallel to the mineralisation direction.
Diagrams Appropriate maps and sections

intercepts should be included for
any significant discovery being

depth plunging steeply to the west underneath the high-grade copper-gold
mineralisation, and also to the west of the Maalinao-Panyaw fault. The
location for the possible high grade copper-gold to the west include at
depth, due to the interpretation that the fault has downthrown the geology

not commercially sensitive. mineralisation, there is considerable scope for further discoveries of two
defined deposit types at the MCB Tenement.

Porphyry copper-gold deposit types

There are extensive intrusions in the area that are directly relate to the
copper-gold mineralisation and which could at multiple locations formed
significant high-grade copper-gold deposits. It may be inefficient to drill test
for new deposits of this style due to the high cost and logistics involved with
diamond drilling in a mountainous region where the tenement in situated.

If possible, there may be a benefit to reviewing the latest options available
for helicopter bourne geophysical surveys especially for magnetic and
electromagnetic systems. It may also be useful to again try some more
detailed ground IP surveys to assist with the more specific drill targeting of
additional porphyry copper deposit types at the MBC tenement.

Epithermal vein hosted deposit types

It is considered likely that there could be a combination of narrow high
grade, and/or more broad large scale and lower grade epithermal deposit
types that are closely related to the porphyry copper-gold deposits at MCB.
An initial approach for the exploration of this deposit type would be to use a
combination of detailed magnetics (to try and define broad structural
features) and resistivity surveys, which are likely to show if some structures
host significant silica alteration. This approach has been proven in the
pacific rim deposits to have been successful in identifying the large gold
systems in this geological environment (Hoshcke, 2008) and would be
worthy of consideration for any future exploration effort which is focused on
the discovery of additional gold mineralisation.

what could be observed from the drill core by the Author. In addition,
copper sulphides and recently weathered copper-sulphides (due to
exposure of the drill core at the surface) are observable in the drill core

has not been able to walk directly on the site Property due to an extended
lock-down of the region to protect the local community as part of the
quarantine steps undertaken locally due to the risks associated with the
COVID-19 global pandemic.

The inability to walk onto the Property has been mitigated by an interview
with one of the experienced geologists (Mr Francis Escasio) who was
working for Freeport McMoRan at the Property over the period of 2007 to
2017. Mr Escasio is a member of the Geological Society of the Philippines

The copper-gold mineralisation at MCB is typical for a porphyry copper-
gold deposit with the geometry of a very thick body, up to 100m in true
width for the high grade core, and surrounded by over 400m in true width
of additional lower grade copper mineralisation, as a relatively elongate
body which stretches out parallel to the contact between the intrusive
tonalite and the host rock basaltic rocks

Away from the central core, the high grade copper-gold mineralisation
extends further as a narrow structurally controlled sheet, interpreted again
to be mostly parallel to the tonalite – basalt contact, with some possible
extensions extending along interpreted structures which exist in a north-
north-west orientation. Both structural sets are close to vertical and their
intersection points also are very steeply dipping.

Estimation
and modelling
techniques
The nature and appropriateness The MCB geological models and interpretations were created using Leapfrog
Geo V5.1 and the subsequent block models and reported Mineral Resource
estimate competed in Leapfrog Edge.
Ore Domains

A combination of features were utilized to review and subsequently
domain the copper mineralisation to an appropriate level for the purpose of
estimating the copper and gold contents.
High Grade Copper Domain

A high-grade ore type called “Ore Type 1” was based on alteration
features, magnetic susceptibility readings and copper grades. A summary
of the statistics for the copper grades associated with this defined domain,
identified a population above 0.5% copper (82%) within this defined ore
zone.

In addition, the spatial location of this ore type was predominantly situated
across a tonalite and mafic volcanic contact position.

For the purpose of defining an ore domain that obeyed the observed
trends and geological controls on the mineralisation, the Type 1 ore
positions were reviewed relative to the potential continuity of this ore type.

In locations where this ore type was very narrow, or patchy and no
observable continuity, this ore type was not defined as a Type 1HG
domain.

In positions where the larger and more continuous Type 1 sections were
observed, the ore domain was further reviewed for possible continuity
along the trend of the tonalite/mafic volcanic contact position. In some
cases, the Type 1HG domain was extended into a larger body, where
there appeared to be additional high-grade copper mineralisation that
extended as part of this mineralized domain in 3D space along the
tonalite/mafic contact position.
Low Grade Copper Domain

Further grade continuity models were created surrounding the high-grade
material, with observable boundaries which are parallel to the
tonalite/mafic volcanic contact position. This position is close to vertical
and striking at between 40 and 60 degrees in line with the broader trend of
the tonalite body and associated alteration and structures.

There appear to be a natural geological boundary at close to 0.2% copper,
which has been used as the basis for developing a surrounding low-grade
domain which is substantially mineralized. The position for copper
mineralisation is not necessarily at exactly 0.2% copper, however, it is
observable that there are distinct trends with grade distributions roughly
above and then below into waste domains across this position. For
example there is a distinct low grade trend in the middle of the tonalite
body which is parallel to the dip and strike of the main structural trend.
This observation and apparent close link to the grade trends with the
geological contacts and alteration was the basis for creatinga lowgrade

domain which ensured that the data from the waste material was not domain which ensured that the data from the waste material was not
mixed with the broader lower grade trends as part of the Mineral Resource
estimate.
Therefore, a low-grade domain boundary was created which obeyed the
general trend of the contact position between assay results which were
above and below 0.2% copper and for which this contact position was
distinctly parallel to the dominant geological trends.
Block Size
Initial models were evaluated using a parent cell size of 20m x 20m x 20m
which were ultimately proven to be very coarse for appropriate ore
definition within the narrower sections of the mineralised bodies, and
relative to the dominant sample size of 2m. A final parent cell size of 10m
x 10m x 10m was ultimately used as the final model block size which
appear to appropriately fill the model with cells and is considered
appropriate for any potential economic evaluation of the Mineral Resource,
which is most likely considered to be via the block caving method.

After applying the constraints on the ore domains for the high-grade and
low-grade domain boundaries, each dataset was reviewed in terms of their
basic statistics and a review of their potential continuity based on their
variograms.

A review of the statistics for each domain did not identify significant high
value outliers that are considered likely to result in an overestimated either
locally or globally to the grade distribution within the block model.
Therefore, no top cut was applied to the Mineral Resource estimate.
Variogram analysis.
The variograms were analyzed in a direction which is parallel to the
dominant geological trend of approximately 90 degree dip at a strike of 50
degrees.
The down hole analysis and all the variograms for 3 directions in the low
grade and high-grade domains appear to indicate a consistent nugget
effect of less than 0.2 (averaging 0.15).
In summary, various orientations all show that the relationship between
samples is lost at between 190m and 300m distance along both the major
and semi-major directions in the plane of the dominant geological trend.
In the opposing minor direction (out of the plane of the main geological
trend) the Sill was mostly reached at a distance of 190m for the high grade
and 120m for the low grade, although more confidence could be applied to
a 100m distance.
The primary plunge direction for the mineralisation based on the variogram
analysis could be interpreted to be at either 50 degrees or at 160 degrees.
In addition, within the low grade domain, it was observed that some of the
data appears to have a better continuity in the minor direction, indicating
that there may be some influence or continuity perpendicular to the
defined 50 degree trend. This is interpreted to be related to a series of
350 degree striking faults which are potentially the cause of, the main
high-grade domain which is close to the Maalinao-Panyaw fault.
Interpolation method
After definition of the ore domains and subsequent statistical analysis and
variogram analysis were completed for each ore domain the following
interpolation methods were chosen.

Search Ellipse parameters
For the purpose of determining the appropriate estimation method and
basis for defining the grade distribution within the MCB block model, the
drill hole data locations relative to the geological interpretation and
potential continuity for the mineralisation based on the variograms were all
taken into account.
It is observed that the drill hole data is clustered against the Maalinao-
Panyaw fault, with a significant gap to the north-east at depth. In addition,
at shallow levels there is a distinct change in the geology and grade
distribution within 200m of the high-grade zone. At depth (below ~300m
RL) the high grade domain (Type 1HG) is not well defined due to lack of
the drill hole data, and there is limited confidence at this stage that this
domain extends for more than 200m down plunge extending away from
the existing drilling information.
The Type 1HG domain and surrounding Type 3LG domain have been
interpreted to extend along strike, with some support for this continuity as
the mineralisation moves form a tonalite/basalt contact into a
tonalite/tonalite contact position.
Based on a combination of the changes to the geology and the statistics, it
was considered appropriate to apply a maximum distance of 200m to both
the major and semi-major axis positions and 100m in the minor direction
for the limits of the Indicated Mineral Resource (first pass), with a minimum
number of samples at 4 and maximum number of samples at 20.
The Inferred Mineral Resource (second pass) was extended for twice this
distance pushing the limits of the second pass search ellipse to 400m x
400m x 200m, with a minimum of 2 sample and maximum of 15 samples.

Cut-off

The basis of the adopted cut-off

The MCB Mineral Resource has been limited to a defined body of copper
and gold mineralisation which are predominantly above 0.2% copper on
average. The boundaries to this Mineralisation are parallel to the
dominant geological trends and the genetically related intrusive tonalite
bodies that have been interpreted at MCB.

The 0.2% lower limit is also broadly in line with the expected economic
limits of the likely mining and processing options considered for the MCB
deposit. This is based on both mining and processing of the adjacent
Batong Buhay deposit and the dimensions and distribution of the
mineralisation at MCB.

Therefore, a preferred lower cut-off grade of 0.2% copper was applied to
the reporting of the Mineral Resource estimate which is based on the
information provided in this report (Table 1).

The copper and gold mineralization at MCG has a distinct higher grade
central core which offers the alternative of developing a smaller mining
operation using a higher cut-off grade. These alternatives are likely to be
reviewed at cut-off grades ranging from 0.2% copper up to 0.5% copper
(see tables 1 to 4).

Mining factors

assumptions
Assumptions made regarding
Information pertaining to the historical mining and processing of a similar
copper-gold deposit on the adjacent Batong Buhay Property provides for a
basic set of assumptions that can be used as a reasonable basis for which
there are prospects for future economic extraction of the reported Mineral
Resource estimate at MCB. The information pertaining to the Batong
Buhay deposit that are relevant to this assessment include the ability to
use a large-scale block caving method, in addition to producing a copper-
gold concentrate with reported recoveries in excess of 80%.

It has been assumed that the large bodies of copper-gold mineralisation
that are considered likely to form a continuous body of mineralisation
potentially amenable to block cave mining have been included within the
reported Mineral Resource estimate. Isolated or narrow structurally
controlled sections of copper-gold mineralisation at this stage at MCB do
not appear to be of a scale to suggest that they have reasonable
prospects for eventual economic extraction and are therefore not included
in the reported Mineral Resource estimate for MCB.

Benchmark mining costs of US$10/t to US$7/t and processing costs of
US$7/t to US$4/t respectively for a medium sized (5Mt to 10Mt per annum)
underground block caving mining method and processing using floatation
to produce a copper-gold concentrate have been assumed where
applicable for the Mineral Resource estimate.

This cost range estimate matches closely with a broad geological cut-off

A lower cut-off grade of 0.2% copper has been used as the preferred lower
cut-off grade for the reported Mineral Resource estimate, which is
considered appropriate based on the geological continuity associated with
copper mineralisation above 0.2% copper in addition to a broad economic
cut-off point based on a US$3.0/lb copper price.
Metallurgical
factors or
assumptions
The basis for assumptions or
There is no reported metallurgical assessment or testing completed from
the exploration activities defined to date at MCB. However, there is some
important information that has been obtained for the processing method
and general copper and gold recoveries from an adjacent porphyry copper
deposit (Batong Buhay).

The Batong Buhay deposit is interpreted to be the same deposit style and
also from the same geological event as the MCB copper-gold
mineralisation. It is therefore a reasonable assumption at this stage,
without any further specific metallurgical testwork, that the metallurgical
characteristics at MCB are likely to be similar to the Batong Buhay deposit.

Public reports from the current owner of the Batong Buhay deposit
(PMDC) report that historical mining by the previous operator (Philix) in
1984 was underground mining via block-caving methods followed by
mineral processing via floatation methods to create a copper-gold
concentrate product for sale. The reported recoveries using the floatation
technology at the time is estimated to have been in excess of 80% for
copper and in excess of 70% for gold into the copper concentrate. It is
considered likely that further advances in floatation technology since 1984
could further improve the level of recovery for both the copper and gold if
the assumption is correct that the copper-gold mineralisation at MCB has
similar metallurgical characteristics to the Batong Buhay copper-gold
deposit.

assumptions
Assumptions made regarding
The MCB deposit exists within a relatively high mountain range with local
regions containing high topographic relief, ranging from 800m in the
valleys to over 1,300m at the surrounding mountain peaks.

No detailed mining assessments has been made with regard to a full
assessment of the environmental factors required for a new Mining
Operation at MCB. However, the current assumptions that has been
made which largely take into consideration the likely environmental factors
that will need to be managed for any proposed mining operation at MCG
include the following:
o
The current assumption is that the mining method will be an
underground block cave, with limited surface disturbance associated
with the mining activities.
o
The waste and tailings products will in part be backfilled to limit the
surface disturbance and fit within the requirements of a site which is
both high relief and high rainfall, and allowing for the expected levels
of erosion that naturally occur at the MCB area.

There are currently no known additional impediments or environmental
controls required to a proposed mining operation at MCB that have been
considered outside of the assumptions above.

this stage the determination of
potential environmental impacts,
particularly for a greenfields
project, may not always be well
advanced, the status of early

Discuss assumptions for bulk

evaluation process of the different
materials.

Bulk density measurements were routinely taken throughout the drilling
campaign and are available for all the defined ore domains. The method
used to collect the specific gravity information for each drill hole is
summarised in the sampling and core management procedures from an
internal report by Freeport-McMoran. These procedures are summarised
as follows:
o
Specific gravity is determined by weighing a dry core sample in air
and as submerge in water.
o
Two 10 to 15 cm long split core samples are collected from each
sampling interval, one near the start and the other near the end of the
interval.
o
Samples were weighed in air, weighed suspended in water, and
weighed in air again to determine its saturated weight.

A review of the bulk density measurements identified that there is minimal
variability in the bulk density measurements, apart from some generally
lower values that exist closer to the surface, or within the top 100m from
surface.
 To apply a more accurate estimation of the specific gravity to the block
model and Mineral Resource estimate at MCB, an inverse distance (x2)
estimation method was used to interpolate a value of the specific gravity
throughout the block model based on 2m composited drill hole data for
each ore domain.

Classification The basis for the classification of
the Mineral Resources into
Indicated Mineral Resource Classification

The grade distribution within the MCB block model was classified as
Indicated where the geology and associated copper-gold mineralisation,
within a constrained high grade (Type 1HG) or low grade (Type 3LG)
domain could be confidently extrapolated based on the understanding of
the mineralisation deposit type, the current distribution of the drilling
information and the information obtained from the variogram analysis.

Based on a combination of the changes to the geology and the statistics, it
was considered appropriate to apply a maximum distance of 200m to both
the major and semi-major axis positions and 100m in the minor direction
for the limits of the Indicated Mineral Resource, with a minimum number of
samples at 4 and maximum number of samples at 20.
Inferred Mineral Resource Classification

The Inferred Mineral Resource was extended for twice the distances
applied to the Indicated Mineral Resource pushing the limits search ellipse
to 400m x 400m x 200m, with a minimum of 2 sample and maximum of 15

Where appropriate a statement of
The relative quality and detail associated with the drilling information which
underpins the Mineral Resource estimate for MCG is considered to be of
high standard. This has enabled the author to establish a high level of
confidence associated with the geological interpretations and definition of
the various ore domains.

The analysis of the drill hole data statistics within each respective ore
domain has identified a relatively good correlation and consistency of
assay data for hundreds of meters, with some local variations being
consistent with what would be expected within a relatively large porphyry
copper style of mineral deposit.

The current level of Inferred and Indicated Mineral Resource estimates are
considered appropriate relative to the data distribution and confidence in
the distribution of the copper and gold mineralisation.

There only issue that has prevented some portion of the Mineral Resource
estimate from having a higher level of confidence up to the Measured
category is due to the drill hole data not being location over an even
spacing and distribution. There are many locations where the drill hole
data cross over, and then extends away for distances to over hundreds of
metres apart where the domain boundaries exits.

information should result in the ability to improve the confidence in the
