Mineral Resource update for Sagay Mining Project

HIGHLIGHTS

• Focus of the update related to shallow supergene copper mineralisation which now includes Measured and Indicated Mineral Resources.

• Combined Measured, Indicated and Inferred Mineral Resource of 312 million tonnes @ 0.39% copper and 0.11g/t gold.

• Global Resource remains largely unchanged with ~1.2 million tonnes of contained copper and ~1 million ounces of contained gold.

• The copper mineralisation remains open in multiple directions, with further shallow targets untested.

• Mineralisation exists from near surface down to over 1.2km depth with strike lengths up to 1km and true widths extending into the 100’s of metres.

____________

Celsius Resources Limited (“Celsius” or “the Company”) is pleased to announce an updated JORC compliant Mineral Resource estimate (“MRE”) for the Sagay Copper Project (“Sagay” or “Project”), held under its Philippine Subsidiary, Tambuli Mining Company, Inc (“TMCI”) and located at the Island of Negros in the Philippines.

The update to the MRE at Sagay is largely based on the results from the 2023 drilling program at a shallow copper position located ~500m to the west of the main body of mineralisation discovered to date, as announced on 17[th] October 2023. This shallow copper zone offers Celsius the opportunity to investigate a low cost start up opportunity via a feasibility study which has been submitted to the Philippine Government.

Celsius Resources Managing Director, Peter Hume said:

“The greater definition of the shallow supergene copper at Sagay has increased both the Resource category and our own confidence in the ability to look at a new shallow sustainable friendly development option. The previous Mineral Resource[1] only placed this area in the Inferred Category, and with this new update to the Mineral Resource, this area is now largely in the Measured and Indicated category, which allowed us to complete and submit a feasibility study to the Philippine Government[2] .

The Company has taken a sustainable approach to the proposed development of the Sagay Mineral Resource, similar to its flagship MCB project. Eliminating the use of a conventional tailings dam and using the tailings for environmental rehabilitation, along with processing the ore through gravity separation, therefore eliminates the use of chemicals. We are in the process of finalising the Project’s environmental impact assessment which will clearly demonstrate the Company’s commitment to environmental protection and preservation through advanced mining technologies.”

CLA Chairman, Atty. Julito R. Sarmiento added:

“The development of the Sagay Project can assist with meeting the global demand for green metals in an effort to transition to clean energy sources and achieve the global goal of net zero emissions by 2050 to stave off climate change calamity. CLA constantly takes serious efforts to develop genuinely responsible projects by tightening up our environmental managements systems and stepping up our social and environmental performance.”

THE SAGAY COPPER-GOLD PROJECT

Location

The Sagay Copper Project is in the north-eastern part of Negros Island, within the cities of Sagay and Escalante in the Province of Negros Occidental, Philippines (Figure 1). Negros Island is part of the central group of Islands in the Philippines commonly referred to as “the Visayas”.

Mineral Resource Estimate

Drilling at Sagay has broadly defined a large-scale copper mineralisation which is interpreted to be a typical porphyry copper style of mineralisation, common throughout the Philippine archipelago.

The copper mineralisation for the MRE at Sagay is defined by three defined mineralised domains, two of which (namely 100LG and 100HG) relate to a main body of copper mineralisation which exists underneath a local topographic high.

This topographic high relates to Purok Tan-ao with resistive siliceous rocks interpreted to be an eroded lithocap associated with the porphyry mineralisation.

A third mineralised domain (900SG) hosts a shallow flat lying supergene copper mineralisation towards the west of the main mineralisation underneath Purok Tan-ao and is possibly related to

==> picture [595 x 18] intentionally omitted <==

ASX RELEASE | PAGE 3

==> picture [594 x 77] intentionally omitted <==

a satellite porphyry mineralisation. Figures 3 to 7 show a plan view and cross sections of the mineralised domains relative to the host rock geology.

The copper mineralisation at Purok Tan-ao is broadly constrained by a zone of mineralisation which exceeds 0.2% copper and is trending parallel to the main alteration and related intrusive host rocks.

A lower cut-off grade of 0.2% copper was applied in the reported MRE ( summarised in Table 1 ) which aligns broadly with the expected economic limits of the likely mining and processing options considered at Purok Tan-ao.

Geology and Geological Interpretation

Sagay is located at the northernmost tip of the NNE trending volcanic arc related to the eastward subduction beneath the Negros Trench in the southwest offshore of Negros Island. Several porphyry and epithermal mineralisation targets belong in this underexplored mineralisation trend along the eastern side of the island.

The major rocks identified at Purok Tan-ao are a series of intermediate igneous rocks intruding into older host rocks composed of basalts overlain by metamorphosed sedimentary rocks and felsic volcanics. These rocks are in turn overlain by Quaternary pyroclastic rocks that consist of tuff and tuff breccias. The intermediate intrusions include several diorites and andesite porphyry.

Three distinct Diorite intrusives were identified. Following the local nomenclature in Sagay Project, these are (from oldest to youngest) the (1) Equigranular Diorite (MEQ), (2) Mediumgrained Porphyritic Diorite (MPOC), and the (3) Fine-grained Equigranular Diorite (FEQ). These intrusive rocks have distinct textures and visible cross cutting relationships. Widespread strong silica - clay and outer chlorite alteration is notable in the deposit. This 8km by 4km alteration zone is indicative of a large magmatic hydrothermal system.

There are multiple types of porphyry mineralisation observed within the Purok Tan-ao Deposit. The dominant type is related to early-stage porphyry quartz stockwork veins with associated potassic alteration and chalcopyrite as the dominant copper sulphide. A later-stage porphyry Cu-Mo type mineralisation has been identified and is hosted in silica – sericite – chlorite alteration. In addition, evidence exists for a later-stage epithermal vein deposit type which exist within close proximity to the large-scale porphyry copper-gold mineralisation.

At this stage, only the porphyry copper-gold type of deposit was defined in the MRE.

Drilling Techniques

All of the drilling data used for the Sagay MRE is based on diamond drilling information from a total of 45 diamond drill holes—with a cumulative meterage of 25,782.1m.

Initial diamond drilling was conducted between December 2012 and 2016 by FreeportMcMoRan, who completed a total of 28 drill holes at Purok Tan-ao, with an aggregate core depth of 22,516.70 metres.

From November 2021 to April 2022, Celsius has completed a total of 4 drill holes and 1 offset, for a total to 2,440 metres[3] . More recently in late 2023, Celsius completed a further 12 shallow drill holes which are the focus for this Mineral Resource update. These shallow drill holes relate to the 900SG mineralised domain with a total meterage of 824.7m[4] .

Sampling and Sub-sampling Techniques

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

Half core samples were collected from diamond holes drilled from the surface. All drill cores were generally sampled at 2m intervals. In cases where geological and mineralogical characteristics change, the sample length is reduced to best fit the geological contact, with a minimum observed sample size of one metre. Sampling typically commenced after the overburden horizon depth was exceeded.

Cut samples were bagged on site prior to delivery to the laboratory (Intertek) in Manila for sample preparation and analysis.

Sample Analysis Method

All samples were analysed at the Intertek, an internationally recognised and ISO/IEC 17025:2005 & ISO/IEC 17020:2004 certified independent laboratory in Manila.

Copper (Cu) values were analysed by means of multi-acid (4-acid) digest. Elements were determined by ICP-OES/MS with AAS finish. Samples were fire assayed for gold (Au) using a 50gram charge, with a detection limit of 0.005 ppm.

Estimation Methodology

A parent cell block size of 10m x 10m x 10m was chosen based on the general dimensions of the interpreted ore domains, and the likely mining method.

Ordinary Kriging was chosen as the interpolation method for the block model which defines the MRE.

The parameters for Ordinary Kriging were based on an analysis of the variograms for each domain in addition to some broad assumptions with regards to the direction and continuity of the copper and gold mineralisation associated with each defined mineralised domain. The variograms were located along the plane of the interpreted controlling geological trend which is striking at approximately 50 degrees at a near vertical dip.

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 MRE.

Classification Criteria

The mineralisation is constrained within boundaries which are also considered to define the limits for each domain as supported by the current drill hole information. Within these domain constraints, minimum search distances and composited drill hole information parameters determined which locations were defined as Measured, Indicated, Inferred or as further Exploration Targets.

A small portion of the 900SG was classified in the Measured category where there is tighter drill spacing (less than 50m), multiple drill holes which show continuity of mineralisation and the variogram analysis is also supporting of the relationship of the assay data between drill holes.

The Indicated category was classified based on maximum distance of 150m to the major position, 85m to the semi-major axis and 25m in the minor direction for the limits, with a minimum number of samples at 8 and maximum number of samples at 16. A minimum of two drill holes was also applied for the Indicated category.

The Inferred Mineral Resource represents over 90% of the total MRE due to the thick and broadly spaced copper intersections as deeper levels which contain the most copper mineralisation identified to date at Purok Tan-ao. This category was extended for twice the distances applied to the Indicated Resource pushing the limits search ellipse to 300m x 150m x 50m, with a minimum of four samples and maximum of 20 samples defined for each block.

No restriction on the number of drill holes was applied for the Inferred Mineral Resource category.

Cut-off Grade

A preferred lower cut-off grade of 0.2% copper has been used in the reported MRE. This 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$10,000/t copper price.

Dimensions

The mineralisation at Purok Tan-ao is classified as a porphyry copper-gold deposit which, at deeper levels (below 400m depth), has a broad geometry of up to 1km along strike towards the north-east (with a main trend of ~45[o] azimuth) and true widths of up to 280m. At shallower levels, the copper mineralisation is broken up into multiple domains which are individually up to 600m along strike and with true widths of up to 150m.

The 900SG domain is a shallow, flat lying zone of mineralisation which has formed along the current and ancient water table at a broadly horizontal orientation. This domain is elongated in the direction of some interpreted controlling faults and/or source porphyry copper mineralisation. These trends appear to be both north-east and north-west in orientation.

Metallurgical and Mining Parameters

For the 900SG domain which is the basis of the Feasibility Study, utilised a potential surface mine approach with an interpreted costs of US$3.30/t for mining and US$4.8/t for processing.

Possible later mining development 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

ASX RELEASE | PAGE 9

==> picture [594 x 77] intentionally omitted <==

mining method and processing using floatation (to produce a copper-gold concentrate) have been assumed where applicable for the MRE.

This cost range estimate matches closely with a broad geological cut-off grade of between 0.15% copper and 0.25% copper (at a forward-looking Copper Price of ~US$10,000/t).

Study Results

Based on the resource model, mining parameters, and metallurgical test works, a Mining Project Feasibility Study was submitted to the Philippine Mines and Geosciences Bureau on 20 December 2023 confirming the presence of minerals in the area which are recoverable by processing the ore through gravity separation which was determined to be economically sound, ensuring environmental protection and preservation methods would be implemented through the advanced mining technologies[5] .

The study focused on the shallow supergene chalcocite deposit which is suitable for a mediumscale surface mining operation. The copper concentrate produced will have no deleterious elements which makes it highly marketable.

Technical, environmental, and social considerations were incorporated in the mine design to reduce the mine footprint to approximately 20 hectares. The process plant is engineered to enhance the ore through a gravity concentration method which is effective in extracting valuable components form the ore, thus contributing to the overall success of the ore beneficiation process.

Metallurgical test works indicated that the tails produced is non-acid generating. All tailings will be managed through dry stacking method which eliminates the need for a tailings dam, thus removing the possibility of environmental impacts (tailings spill). Other alternative disposal methods are currently being studied, including the potential use of tailings for hollow block manufacturing as a community livelihood program, road base, and landfill among others.

Next Steps

Following the submission of the DMPF, the key technical, environmental, and social plans and programs are under review by the Philippine Government. Once approved, the Company will apply for a mineral agreement with the government.

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 metres. Downhole surveys were also completed using a Keeper Gyro at 50m intervals. • Collar surveys were then logged into the master MS Excel spreadsheet as part of the database.
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.	• In the MRE, drill hole assays were composited to 2 metres which matches closely with the sample length down hole for all drill hole sampling completed at Sagay. • The drilling completed at Sagay is dominantly towards the north-west or south-east which is perpendicular to the main trend of the copper mineralisation and host rock geology. The drill spacing for the drill holes in this orientation is irregular, ranging from just over 150m separation up to 400m separation. • Drill hole spacing for the 900SG area have been reduced to between 50m and 100m with the results from the 2023 drilling program. • Some drilling has been conducted towards the south-west which is sub- parallel to the main trends of copper mineralisation. These drill holes have not had a significant influence on the MRE due to their poor orientation for both the copper boundary definition and for sampling. • The drill hole spacing has broadly defined the major trends to the copper- gold mineralisation.

The drill holes which are dipping approximately 60 degrees towards the south-east appear to be at a good angle to effectively test the copper- gold mineralisation in this trend. The holes which have been drilled towards the south-east are optimal for some cross cutting north-west trending structures, but at a poor angle to test the dominant copper-gold mineralisation which is sub parallel to these drill holes. • The 900SG domain is at a horizontal orientation and drilling has largely been completed at a 60-degree angle which is appropriate for defining both this flat lying domain in addition to potential vertical feeder structures related to the primary porphyry copper source of this supergene copper domain.
Sample security	• The measures taken to ensure sample security.	• The following standard procedures were documented to have been followed in relation to sample security for all Purok Tan-ao diamond drilling: Sample bags are arranged in sequence according to its sample number. These are then weighed and jotted down to a sample dispatch note which details the sample numbers, sample type and laboratory processing required. Geologists ensures that the transmittal form is correct for encoding and submission. The samples are checked by a Mines and Geological Sciences (MGB) Geologist before issuance of an Ore Transport Permit (OTP). Upon receipt of the OTP, the sample bags are sealed in a crate, and sent to Manila via a certified courier contractor. Upon arrival in Manila, a company vehicle checks the samples before they’re delivered to Intertek Testing Services.

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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. •	• The Sagay Copper project is at the north-eastern part of Negros Island within the Cities of Sagay and Escalante Negros Occidental. • The underlying title is in the name of the Philippines registered corporation Tambuli Mining Company Inc. (TMCI) is currently 100% owned by a private Delaware Company who in turn is owned by Celsius Resources Ltd. • Tambuli Mining Company, Inc. (TMCI) was first granted a single Exploration Permit denominated as EP-000003VI on 6 May 2008 under Phelps Dodge Exploration Corporation – Philippine Branch (PDEC), which was later acquired by Freeport-McMoRan Exploration Corporation – Philippine Branch (FMEC) in 2007. The permit area covers a total of 4,594.23 hectares, which has recently been reduced to 1,791.3736 hectares where the Deposit is situated. • On August 11, 2021, TMCI, now a subsidiary of CLA, was granted a fourth exploration permit renewal (extension) which is valid until February 10, 2024. The current two-year renewal period allowed the resumption of ore definition drilling activities aimed to define the deep ore zone (two drill holes), its shallow/near surface extensions (three drill holes), and test possible near surface chalcocite ore zones (three drill holes). • TMCI has recently submitted an application for a Declaration of Mining Project Feasibility (DMPF), which is the first step towards a further application of a mining permit which will allow for the further exploration and development of the Sagay Project once granted.

		• From 2012 through to 2016 the exploration activities were focused on diamond drilling to test the targets identified from the work completed over 2008 and 2009. • A further exploration under Celsius Resources commenced between November 2021 to April 2022, completing a total of 4 drill holes and 1 offset hole in the prospect, with a cumulative depth of 2,440.70 meters. • The most recent drilling program was completed in late 2023 with 12 shallow diamond drill holes for a total length of 824.7m • The drilling activities were predominately at the Purok Tan-ao with all drilling results reported in this release.
Geology	• Deposit type, geological setting and style of mineralisation.	• The geological setting for the Purok Tan-ao 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 predominantly within a series of large intrusive bodies that have intruded the host country rocks. • The Sagay Project host rocks are part of the Negros Occidental Island, which is situated in western Visayas, Central Philippines. The eastern part of the island comprises a NNE trending volcanic arc related to the eastward subduction beneath the Negros Trench in the southwest off- shore of Negros Island. • The major rocks identified are a series of intrusions which exist within an older host rock setting of basalt rocks that are overlain by felsic tuffs and metamorphosed sedimentary rocks. These rocks are in turn overlain by Quaternary pyroclastic rocks that consist of tuff and tuff breccias. Intrusions include diorite and andesite porphyry. Post-mineral Pliocene to Pleistocene andesitic to dacitic volcanics cover the northern part of the area. • Three distinct diorite intrusives were identified, following the local nomenclature in the Project, these are (from oldest to youngest) the: (1) Equigranular Diorite (MEQ), (2) Medium-grained Porphyritic Diorite (MPOC), and the (3) Fine- grained Equigranular Diorite (FEQ). These intrusive rocks have distinct textures and visible cross cutting relationships. • Widespread strong silica clay and outer chlorite alteration is notable in the deposit. This 8km by 4km alteration zone is indicative of a large

		magmatic hydrothermal system. the surface alteration is approximately 1.7km by 1.7km, which tends to extend southwest along possible controlling structures. • The following are the established ore types in the deposit: o Ore Type 1 – Early porphyry to late porphyry mineralisation o Ore Type 2 – Mixed zone of late porphyry mineralisation and epithermal mineralisation. • Ore Type 3 – possible mixed zone of supergene enrichment and high sulfidation to intermediate sulfidation epithermal mineralisation. Divided into OT3A and OT3B based on the associated mineral assemblages.
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. • 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.	• In summary, the drill hole in the database for the Property which relate specifically to the Purok Tan-ao area consists of 45 diamond core drilled holes with an accumulative meterage of 25,782.1m after the inclusion of the drill holes which are the subject of this release. • No drill hole information has been excluded.

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 (e.g. ‘down hole length, true width not known’).	• There are a number of drilling orientations, but generally drill holes were designed on lines oriented towards 130 degrees to the south-east or towards 220 degrees to the south-west and spacing at just over 200m between holes. Where the mineralisation is interpreted to strike roughly perpendicular to the orientation of the drill holes, the angle between the drill hole (typically at a 60- degree dip) and the vertical mineralisation implies true width ranges of between 70-90% of the downhole width.
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.	• See figures 3 to 7 for a representative plan and cross sections of the Geology and its relationship to the copper-gold mineralisation at Purok Tan- ao.
Balanced reporting	• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting	• All data for the project has been collected, validated and reported and is considered to be a fair representation of the MRE from the Sagay Project which is the subject of this release.

Further drilling along possible north- east or northwest orientations to the previous shallow copper-gold intersections is warranted to test the extent of this mineralisation. • Apart from the direct extensions to the currently defined copper-gold mineralisation, there is considerable scope for further discoveries of two defined deposit types within the Sagay Tenement as follows: • Porphyry copper-gold deposit types o There are extensive intrusions in the area that are directly related to the copper-gold mineralisation, and which could at multiple locations formed significant high-grade copper-gold deposits.

There are a number of apparent large-scale structures which exist adjacent to Tan-ao which are worthy of follow up drill testing for this style of deposit. There may be some merit in further surface sampling with a greater emphasis on epithermal gold deposit types.

Criteria	JORC Code explanation	Commentary
Database integrity	• Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. Data validation procedures used.	• The original assay sheets and drill logs were checked against the drill hole database by the author and no systematic or random errors were identified as part of this validation check of the database. • In addition, the original laboratory reports were checked against the drill hole database. This data review did not identify any systematic or isolated errors in the drill hole database. • Drill core observations and validation steps were completed in September 2022 which included a review of all the defined Ore Domains and broad contact positions between the high grade and low- grade domains in addition to the low-grade ore to waste domain boundaries. • All drill core from the Purok Tan-ao drilling which were used to define the 2024 MRE have been preserved and were available for the author to visually check against the drill logs and recorded assay results. • Geological observations that are recorded in the drill logs leading to the definition of the ore domains at Purok Tan-ao appear consistent and reflective of 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 where high-grade copper mineralisation has been reported. The relative presence of copper sulphides and oxidised copper minerals appear reasonably reflective of the assay results reported in the database based on the observations made by the author of the drill core.
Site visits	• Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case.	• The Author has completed site inspections of the property including detailed review of the drill core which relate to the Mineral Resource Estimate. The field inspections included validation for approximately 30% of the drill collar locations for the drill holes which are included in the Mineral Resource estimate using a handheld GPS. • The review of drill core and field inspections were conducted from September 28 to September 30, 2021.

Geological interpretati on	• Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology.	• The geological interpretation associated with the Purok Tan-ao Mineral Resource estimate is considered by the author to have a high level of confidence, with limited variability considered likely due to a difference in the geological interpretation. • The interpretation and Mineral Resource estimate have been compared directly with previous interpretations made by the geological staff at Freeport-McMoRan, which completed early stage previous exploration activities at Purok Tan-ao. The copper and gold mineralisation defined in the Mineral Resource estimate has a high level of consistency relative to the geological interpretation completed by Freeport-McMoRan. • The geological controls on the copper-gold mineralisation at the Purok Tan-ao 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.

High Grade Copper Domain High-grade porphyry Cu-Au mineralisation is hosted in older volcanics and in the series of diorite intrusions, but widely situated in Medium Porphyritic Diorite (MPOC). This ore type was defined based on a combination of its alteration mineralogy, high-grade copper (mostly above 0.5% copper) and broad extensions to this mineralisation parallel to the dominant geological trend.

Ore Type 2 (as discussed in Section 13.1) positions were reviewed relative to the potential continuity of this ore type and to see the relationship between its copper-gold mineralisation. In locations where this ore type was very narrow, or patchy and no observable continuity, this ore type was not defined as a 100HG domain. Low Grade Copper Domain Further grade continuity models were created surrounding the high-grade material, with observable boundaries which are parallel to the older volcanics and diorite intrusions position. 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 mineralised. 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. 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 A parent cell size of 10m x 10m x 10m was 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 for later development. ORE CONTINUITY AND STATISTICAL ANALYSIS 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 also a review of their potential continuity based on their variograms. STATISTICS AND TOP CUT The summary basic statistical information for copper, gold and specific gravity associated with each domain, based on the 2-meters composited datasets from within each domain are summarised in the following tables.

		Variogram analysis was competed for the 3 mineralised domains, the results of which are indicated below. 100LG Domain:_The major axis has a strike of 45 degrees which is very close to the observable trend of the geology and interpreted boundaries to the copper mineralisation. The variograms are based on very sparse data. However, it is observed that there is a possible Sill developing for the major direction at over 100m in length, which would possibly be better supported with some closer spaced drill hole information. The semi-major direction has a reasonably good variogram with a Sill at approximately 70m, and the minor axis produces a variogram with a Sill at 20m. _100HG Domain: The higher-grade domain appears to occur as an internal zone with a shallow dip within the 100LG domain. The orientation of this mineralisation is broadly perpendicular to the major trends that are defined in the 100LG domain which is also reflected in the variogram results. The major direction is outlined in a fairly good variogram with a Sill at over 135m in length. The semi-major direction is delineated with a Sill at about 45m, and the minor axis yields a variogram with a Sill at about 25m. 900SG Domain: This patchy near surface supergene chalcocite enrichment zone is constrained to an area which is located to the west of the larger 100 domain. The variograms are based on an evenly scattered drillhole data. The major direction is defined with a Sill more than 90m in length. The semi-major direction is delineated with a Sill at about 85m, and the minor axis yields a variogram with a Sill at about 25m. INTERPOLATION METHOD After definition of the ore domains and subsequent statistical and variogram analysis were completed for each ore domain, Ordinary Kriging (OK) was used as a standard estimator for both copper and gold values.

		• The 0.2% lower limit is also broadly in line with the expected economic limits of the likely mining and processing options considered for Purok Tan-ao. • 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).
Mining factors or assumptio ns	• Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made.	• 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 Tan-ao 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 this Technical Report. • For the 900SG domain which is the basis of the Feasibility Study, utilised a potential surface mine approach with an interpreted costs of US$3.30/t for mining and US$4.8/t for processing. • Possible later 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$10,000/t). • 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 ~US10,000/t copper price.
Metallurgic al factors or assumptio ns	• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but	• A metallurgical assessment was conducted on the 900SG ore which determined it gravity separation would deliver economic results. Further testing would be required on other mineralisation to determine the best processing method. • Apart from the 900 SG ore it can be assumed that Metallurgical characteristics have been assumed to be similar to other porphyry copper deposits throughout the Philippines which have a similar

It is common for other similar deposits to have copper recoveries in excess of 85%.
Environ- mental factors or assumptio ns	• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made.	• No limitations or modification were applied to the Mineral Resource estimate with regard to the environmental factors or assumptions. It is recognised in general that there is limited space and some environmental issues associated with the placement of any waste storage facilities or a tailings storage facility. However, there are also generally considered multiple options, such as backfill of waste and tailing underground, which will still allow for a potential future mining operation.
Bulk Density	• Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been	• Bulk density measurements were routinely taken throughout the drilling campaign and are available for all of 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 reports by Freeport-McMoRan. These procedures are summarised as follows: • Specific gravity is determined by weighing a dry core sample in air and as submerge in water.

	measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.	• 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. • Samples were weighed in air, weighed suspended in water, and weighed in air again to determine its saturated weight.
Classificati on	• The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit.	Measured Mineral Resource Classification • To determine the Measured Mineral Resource, a maximum estimation distance of 50 meters was applied in the major direction, 25 meters in the semi-major axis, and 10 meters in the minor direction. This was complemented by a requirement for a minimum of 10 and a maximum of 16 samples. A maximum of 6 samples per drill hole was applied with at least 2 drill holes needed to be within the specified search ellipse for this category. • The maximum distances applied to the search ellipse parameters for the Measured category were based on the extents of the variogram where there appears to be robust trend, in addition to being approximately 60% of the Sill distance. Indicated Mineral Resource Classification • The grade distribution within the Purok Tan-ao block model was classified as Indicated where the geology and associated copper-gold mineralisation, within a constrained high grade (100HG), low grade (100LG) and supergene enrichment (900SG) domains 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 the combination of the changes to geology and the statistics, it was considered appropriate to apply a maximum distance of 150m to the major position, 85m to the semi-major axis and 25m in the minor direction for the limits of the Indicated Mineral Resource, with a minimum number of samples at 8 and maximum number of samples at 16. 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 300m x 150m x 50m, with a minimum of 4 sample and maximum of 20 samples defined for each block. This was considered appropriate for this level of confidence based on the broad dimensions of the copper-gold mineralisation defined to date at Purok Tan-ao.
Audits or reviews	• The results of any audits or reviews of Mineral Resource estimates.	• No independent audit or review has been undertaken on the updated Mineral Resource estimate for the Sagay Property which is the subject of this JORC Report.
Discussion of relative accuracy/ confidence	• Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. • These statements of relative accuracy and confidence of the estimate should be compared with production data, where available.	• All the available drill hole information relating to the Purok Tan-ao Mineral Resource estimate have been appropriately documented within this Technical Report. The author is not aware of any omission or bias that relates to the information as it has been presented in this report which relates specifically to the Mineral Resource estimate for Purok Tan-ao. • 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, Indicated and Measured 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 larger portion of the Mineral Resource estimate from having a higher level of confidence is due to the drill hole data not being located over an even spacing and distribution. There are distances of over 200m in some locations between drill hole data points which, with infill drilling would be expected to be converted to a higher level of Resource category.
