Kopore Metals Limited (ASX:KMT) ( Kopore or the Company ) is pleased to announce that its wholly owned subsidiary, Kopore (WA) Pty Ltd has executed a binding earn in and joint venture agreement ( Agreement ) with Murchison Copper Mines Pty Ltd ( MCM ), a subsidiary of Horseshoe Metals Limited (ASX:HOR) ( HML ) providing for an earn in and joint venture in relation to the tenements surrounding the historical Horseshoe Lights Copper-Gold Mine ( Horseshoe Lights Mine ).
The Horseshoe Lights Mine is approximately 150km north of Meekatharra in Western Australia. The Agreement relates to an area of 32.4km[2] of largely unexplored land surrounding the Horseshoe Lights Mine ( Agreement Area ) (see Figure 1).
ASX RELEASE | 28 January 2021
Property Details
The Horseshoe Lights Mine was discovered in 1946 and saw commercial production up to 1994. Over this period, approximately 3.3 million tonnes of ore were mined, resulting in production of approximately 56,000t Cu (at an average grade of 1.7% Cu) and 307,000oz Au (at an average grade of 2.9g/t).[1 ]

ASX RELEASE | 28 January 2021
Excluded from the Agreement Area is part of M52/743 upon which, the historical open pit and existing copper resource is located as well as waste dumps and stockpiles tailings from the historical operation (shown as the " Excluded Zone " in Figure 2). The Excluded Zone will continue to be owned by HML. Kopore and MCM have entered into a binding Cooperation Deed which will (together with the Agreement) govern the interaction of their respective rights in relation to M52/743. Kopore is not responsible for any reclamation or rehabilitation costs related to the historical operation under the Agreement or the Cooperation Deed
Agreement Terms
The material terms of the Agreement are:
-
Upfront Payment: $50,000 is payable by Kopore upon satisfaction of certain conditions precedent by MCM.
-
Stage one: Earn in of $1.45 million expenditure to earn a 51% beneficial interest in the Agreement Area over a two-year period. Stage one includes a minimum expenditure amount of $250,000 to be spent in year 1 ( Minimum Expenditure ). Kopore must expend this minimum expenditure amount before it is able to withdraw from the earn-in.
-
Joint Venture: Upon completion of the stage, one earn-in, Kopore and MCM will form an unincorporated joint venture in relation to the exploration of the Agreement Area. The parties' initial respective interest in the Joint Venture will be Kopore 51% and MCM 49%.
-
Stage two: Kopore can elect to expend an additional $1.5 million within a further 2 years to earn into an additional 19% beneficial interest in the Agreement Area. If Kopore completes the stage 2 earn in, the parties' respective interest in the Joint Venture will be Kopore 70% and MCM 30%.
-
Joint Venture expenditure: Following the earn-in, the parties must each contribute to Joint Venture expenses in proportion to their respective percentage interest in the Joint Venture or their interest will be diluted in accordance with a prescribed formula.
Commenting on the transaction, Simon Jackson, Managing Director said:
“We are excited to have the opportunity to earn into a virtually unexplored area of the Bryah Basin right next to a historical high-grade copper/gold mine. We were initially attracted by an untested geophysical target that looks similar to the geophysical signature of the historical mine containing a high-grade gold drill intercept that has never been followed up. This attractive opportunity provides initial targeted areas to be tested with a systematic exploration approach, in areas close to the historically high-grade Horseshoe Lights Mine. We are looking forward to getting on the ground and commencing exploration. The structure of the earn in gives Kopore shareholders an immediate exploration focus in Western Australia. This strategy is in line with the Board’s goal of providing value for Kopore’s shareholders through smart and focussed deals. We are planning an exploration program to achieve the initial $250,000 earn in using existing cash on hand”
Exploration Plan
The Company’s exploration objective is to actively explore identified areas within the Agreement Area on the Horseshoe West mining and exploration license areas for potential additional zones of volcanogenic massive sulphide ( VMS ) copper-gold style mineralisation and/or shear zone hosted gold mineralisation. VMS deposits are commonly found in clusters and the Company is seeking to explore an area within 2km to the west of the historical Horseshoe Lights Mine. The targeted areas have not been historically tested by geochemical or drilling programs but are interpreted to lay within a similar stratigraphic, structural position and potentially shallowest depth to the Narracoota Formation, which hosts the historical Horseshoe Lights Mine.
Page | 3
ASX RELEASE | 28 January 2021
A younger Ravelstone Formation overlies the targeted area, with thickness to be defined through drilling, however the Company believes that in addition to the potential for another Horseshoe Lights VMS style deposit in the Narracoota Formation, gold mineralisation could be discovered in the younger Ravelstone Formation. The Ravelstone Formation is known to host gold mineralisation, as observed at Bryah Resources’ (ASX:BYH) Windalah Gold Prospect, located 13km south of the Horseshoe Lights Mine and interpreted to as in a similar stratigraphic position to the Company’s first target area. Exploration programs within the Ravelstone Formation will test for gold mineralisation within the chert layers and could indicate proximity to the Narracoota Formation contact.
The Company’s initial program will include re-evaluation/reprocessing of the EM, detailed gravity, and magnetic survey data, which has been completed in the past 15 years. Upon government approval, Kopore intends to undertake an initial geochemical survey to cover the area of interest. The results of this geophysical review will assist in enhancing the targeting of a 1,000 - 1,500m reconnaissance drill program, aiming to test this area for potential Horseshoe Lights style VMS repeat and/or shallow orogenic gold mineralisation.

TECHNICAL DETAILS
The information in Table 2 and Figures 2 and 3, relates to all holes within the Kopore Agreement Area that contain a significant intercept, being intercepts over 1m in length with a gold grade of 0.5 g/t of gold or greater ( Significant Intercepts ). A total of 331 drillholes were drilled in the Agreement Area. Kopore has not included:
-
251 drill holes that were not assayed for either copper or gold;
-
73 drill holes that were assayed for copper and gold but did not return a significant intercept.
Kopore does not consider the:
-
251 holes that were not assayed for copper or gold;
-
holes that did not return a Significant Intercept; or
-
intercepts that were not Significant Intercepts,
to be material to the acquisition or Kopore's plans moving forward and has therefore not included these results in the announcement.

| Nature and quality of sampling (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
Total Horseshoe Metals Drilling Information Historical data: All activities completed by Horseshoe Gold Mine Pty Ltd which was a wholly owned subsidiary of Barrack Mines Ltd between 1983-91 and Sabminco NL between 1992-1995. Barrack Mines Ltd drilled 43 diamond holes for 15,353m, 638 Reverse Circulation holes for 55,343m and 19 channel samples for 520m between 1983 and 1990. Sabminco NL drilled 14 HQ & NQ diamond holes for 2672.25m and 108 Reverse Circulation holes for 9,244m between 1992 and 1993. Initial hole spacing was on a nominal spacing of 50 x 50m with infill as required in the pit area. Drillhole deviation resulted in irregular drill spacing as exploration and resource definition progressed. Earlier drilling prior to 1983 has not been used. The majority of holes are orientated perpendicular to mineralisation which is mainly toward mine grid east and north east at various inclinations. |
|
| Sampling Technique |
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used |
Historical data: All drill hole collar locations were surveyed by mine surveyors and the majority of diamond drill holes included downhole surveys using an Eastman camera. Reverse Circulation holes were generally not surveyed down hole. Where possible historical open holes have recently been surveyed for collar location and down hole by contract surveyors. Representative reverse circulation samples were collected using mine practices deemed appropriate at the time and logged for lithological information. Diamond core samples were logged for lithological, structural, and geotechnical information (in some cases). Horseshoe Metals: Certified standard and blanks samples were inserted into the sample sequences in according to Horseshoe Metals QAQC procedures. Duplicate samples for RC and diamond samples were collected to check repeatability of sampling and variability or nugget effect for tungsten mineralisation. Results from this QAQC sampling were considered acceptable. All Horseshoe Metals drillhole collar locations have been surveyed by licensed contractors using RTK DGPS system and drilling contractors provided downhole survey information using single shot |

of deposit that has been subject to strong
weathering and alteration makes identification of
stratigraphical units very difficult. The lack of an
early stratigraphical interpretation model and limited
understanding of the deposit style has also caused
inconsistency in the logging by various geologists.
As a consequence, only the overlying sediments and
underlying shale and dolerite have been logged
according to theirprimary rock type. Barrack Mines|

| Ltd and Sabminco NL used similar mine-specific geological codes to describe the geological units. A metamorphic and alteration methodology was used to describe the volcanic stratigraphy, but interpretation of the various descriptions is very difficult. Horseshoe Metals: Logging of Horseshoe Metals reverse circulation drilling identifies all aspects of lithology, colour, weathering, texture, alteration, and mineralisation. All primary recorded on-site data was directly imported into a drill hole database and checked against the original data. During logging part of the RC sample was sieved, logged, and placed in RC chip trays. The logging also includes references to wet samples in the comments. All reverse circulation samples have been photographed in wet form and the chip trays have been retained for physical inspection onsite or in the Perth office. Original logging of historical diamond core described lithology, colour, and mineralisation content as well as some geotechnical data including core recovery, RQD data and alpha angle measurements. Approximately 10% of the original diamond holes in areas outside the existing pit have been re-logged and photographed so far. Diamond core for Horseshoe Metals holes was logged for recovery and RQD. Information on structure, lithology and alteration zones was recorded. Diamond core trays are stored on site for future reference. All drill data is digitally captured and stored in a central database. |

| were employed during the mining period 1984-1995. Horseshoe Metals: The numbered calico samples bags collected by Horseshoe Metals at the exploration site were bagged into polyweave and bulkie bags and transported to the freight company depot in Meekatharra and then transported by road to the laboratory in Perth. Each laboratory has used appropriate sample preparation facilities and the required analytical equipment. At the laboratory, the diamond core samples were sorted, reconciled, placed in trays on trolleys and dried in a gas oven at 110°C for a minimum of 8 hours or until dry. Samples ranging from 300g - ≤3kg were crushed to nominal ~10mm using a jaw crusher and then pulverised using LM2, LM5 or Mixer Mill pulverisers. Samples >3kg were Boyd crushed to a nominal ~3mm and split in half using Boyd rotary split divider, one half was then pulverised, and the other half retained, bagged, and stored. After pulverising a 150g craft geochemical (pulp) packet was taken directly from the pulveriser bowl and submitted for analysis. Sample preparation for RC samples were similar but did not require the crushing circuit and so went straight to the pulverisers. Samples weighing >3kg were riffle split first and then pulverised. The sample preparation technique is considered to be appropriate. |

| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. |
Based upon historical information and previous resource reporting, KMT is of the opinion that industry standard practices have been employed in previous exploration programs. Historical data: No formal report or information is available but conversations with original mine personnel suggest that industry standard practices were employed during the mining period 1984-1995. Horseshoe Metals: Field QAQC procedures included the insertion of field duplicates, blanks, and commercial standards. Standards were inserted at intervals of 30. If a duplicate or blank falls on the 30th sample, the standard sample number was changed to suit. All laboratory QC data is reported within the structure of the final reports. A blank was included at the start of every job and then after every 90 samples. One duplicate and one CRM were included at random within each set of 24 analysed. One sample preparation split was performed in 25 samples. Wet sieving of at least one sample in every batch was undertaken to confirm % -75um. |

|||Horseshoe Metals: Field duplicates have been taken
on a ratio of 1:50 for RC drilling for Horseshoe
Metals holes, the results of which show good
correlation with original samples. No second half
sampling of diamond core has been undertaken to
date.|
||Whether sample sizes are appropriate to the
grain size of the material being sampled.|Historical data: No formal study is available on this
to date for the 1984-1995 data.
Horseshoe Metals: Sample sizes for Horseshoe
Metals holes are considered to be appropriate to
accurately represent the copper mineralisation at
Horseshoe Lights based on the thickness and
consistency of the intersections, the sampling
methodology and the per cent value assay ranges
for the primary elements.|
|Quality of
assay data
and
laboratory
tests|The nature, quality and appropriateness of
the assaying and laboratory procedures
used
and
whether
the
technique
is
considered partial or total.|Historical procedures: Barrack Mines Ltd and
Sabminco NL predominantly used two laboratories
to assay diamond drill core and RC drill cuttings. The
majority of samples were processed and assayed at
the on-site Horseshoe Gold Pty Ltd mine laboratory
using the following techniques: • assayed for gold
using AAS detection limit of 0.01ppm, • assayed for
copper and silver using traditional AAS wet
chemistry technique with a detection limit of 10ppm
Cu and 1ppm Ag.
Classic Laboratories Pty Ltd (renamed Classic
Comlabs Ltd and then purchased by Amdel Ltd now
Bureau Veritas) was used as a back-up and umpire
laboratory for check sampling and overflow using the
following techniques:
•
assayed for gold using fire assay technique
FAS1 with a detection limit of 0.02ppm,
•
assayed for copper and silver using wet
chemistry technique A1/2 with a detection limit
of 5ppm Cu and 1ppm Ag.
Horseshoe Gold Mine Pty Ltd were aware of the
differences in gold assaying method between by the
two laboratories and considered the method used by
Classic Laboratories Pty Ltd to be more accurate.
No reconciliation study of the differences between
the two laboratories was completed.
Horseshoe Metals Procedures: The copper assay is
derived using a mixed acid digest of nitric,
hydrofluoric, perchloric and hydrochloric acids on
0.2g of sample and analysed using ICP Optical
Emission Spectrophotometry. This method is
considered appropriate and effective for this style of
mineralisation.
The gold assay was derived using an aqua regia
technique where 10g of prepared sample was
digested using nitric and hydrochloric acid. The
sample was then solvent extracted using Methyl
isobutyl ketone and read on a Graphite Furnace
Atomic Absorption Spectrometer. This method is
considered adequate and effective for this style of
mineralisation.|

precision have been established.|Historical data: No formal report or information is
available but conversations with original mine
personnel suggest that industry standard practices

either independent or alternative company
personnel.|Historical data: No formal report or procedure is
available for the historical data, but verification of
significant intersections is considered to have been
the duty of the senior mine geologist at the time.
Horseshoe Metals: All significant intersections have
been verified by the senior geologist and managing
director of Horseshoe Metals Ltd.|
||The use of twinned holes.|Within the Agreement Area, twinned holes have not
occurred.|
||Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.|Historical data: There is no information or formal
report detailing how this process worked. The
assumption is that during the mining period all
assays from the Horseshoe Gold Mine lab had been
handwritten on the geological logs along with
associated sample number. These assays would
have been subsequently hand entered into an ASCII
format.
Assays received from Classic Laboratories Pty Ltd
appear to be in type format and there is no
information on how this data was entered into the
mine database, but the assumption is that it was also
hand entered. This ASCII file was eventually used to
create a Surpac database for section creation and
3D modelling. The original Surpac database file from
March 1995 was used to create the present
database.
Horseshoe Metals: Primary data was collected on
Toughbook laptop computers using a standard set
of Excel or Micromine templates with look up codes.
This information was sent to CSA Global Pty Ltd and
Delta Resource Management Pty Ltd for compilation
and validation into SQL database server.|
||Discuss any adjustment to assay data.|Historical data: Where discrepancies arose between
assay values contained in the original 1995 Surpac
database and the assay values handwritten on the
geological logs, the latter appeared to be more
complete and consequently used for the present
database. Assay values on the original geological
logs deemed unreliable were discounted and
assigned a copper value code so it would not be|

|||used in the resource estimate. Follow up drilling in
these areas has clarified the correct values and used
in the latest resource estimate.
Horseshoe Metals: No adjustments were made,
other than for values below the assay detection limit
which have been entered as the negative of the
detection limit.|
|Location of

industry practices at the time to mark out and pick-
up collar coordinates in mine grid format. The mine
grid
coordinates
have
subsequently
been
transformed into MGA_GDA94 format. All available
historic collar locations still visible at surface have
recently been surveyed using RTK DGPS system by
MHR Surveyors Pty Ltd
Downhole surveys were taken from Eastman
camera discs employed by the various drilling
companies at that time. Selections of these discs are
available on site but have not been verified to date.
Several available historic collar locations still visible
at surface have recently been surveyed down hole
either by re-entering the drill hole with a drill rig then
downhole surveying using single shot digital camera
readings or by DHS (Aust) Pty Ltd using an
Electronic Multishot tool with readings in and out of
the hole every 5m. Stated accuracies are +/- 0.2⁰ for
dip and 0.3⁰ for azimuth.
Horseshoe Metals: All drill hole collar locations have
been surveyed by MHR Surveyors using RTK GPS
referenced to the nearby Standard Survey Mark
PKH4. Expected relative accuracies are 0.02m for
easting and northing and 0.05m for RL.
Downhole surveys consisted of single shot digital
camera readings during drilling. Open holes were
also surveyed by DHS (Aust) Pty Ltd using an
Electronic Multishot tool with readings in and out of
the hole every 5m. Stated accuracies are +/- 0.2⁰ for
dip and 0.3⁰ for azimuth.|
||Specification of the grid system used.|Barrack Mine Ltd created a NW mine grid orientated
over the pit area with an east-west azimuth
equivalent to 89⁰. The mine grid RL was offset from
real RL by 62.2m. These coordinates have
subsequently been transformed to MGA_GDA94
zone 50 using the historic grid transformation.
All recent drill hole data is also recorded in
MGA_GDA94 zone 50.|
||Quality and adequacy of topographic control.|Topographic control was created from known survey
stations and air photography in strict accordance
with Mines Regulation Act 1946 by the authorised
mine surveyor.|
|Data

and
distribution|Data spacing for reporting of Exploration
Results|RC and RAB exploration drilling outside of the pits
environs was generally on a 50 x 50m spacing. RC
resource infill drilling was generally 15 x 30m

irregular but is less than 40 x 40m is most cases.
Deep exploration diamond drilling is also irregular.|

||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.|The historical data spacing, and distribution was not
considered sufficient for the purpose of a modern
resource estimation. Follow up drilling has been
completed to infill obvious gaps in order to provide
sufficient geological and grade continuity. When the
drilling was complete, the mineralised domains
display sufficient geological and grade continuity for
the mineral resource procedures and classifications
applied to support the definition of Measured
Indicated and Inferred Mineral Resources under the
2012JORC code. |
||Whether sample compositing has been
applied.|Historical data: Within the resource area 2m
composite RC & diamond core samples were
routinely taken from 1m splits.
Horseshoe Metals: Sample compositing over a
length of 3 or 4m has been applied to sample|

east which is slightly oblique to the mineralised
trends, but intersection angles are closer to
perpendicular in most cases.|
||If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.|A consistent sampling bias is not considered to be
an issue for the purpose of this resource
estimation. Diamond drilling confirmed that drilling
orientation did not introduce any bias regarding the
orientation of key mineralised structures.|
|Sample
security|The measures taken to ensure sample
security.|Historical data: All drill samples were assayed
onsite at the Horseshoe Gold Mine Pty Ltd
laboratory or at Classic Laboratories Pty Ltd in
Meekatharra or Perth. Pulps have been in storage
on site within the core yard.
Chain of custody is managed by Horseshoe Metals.
All sample numbers are generated in the site office.
Once samples intervals are selected, the numbers
are assigned to each sample. The sample numbers
are not left in the core box (where the sample was
taken from), but the core is marked for the taken
sample intervals so it would be possible to
reconcile the laboratory results against the
particular intervals of core. The sample number,
drillhole name and sampled interval are recorded in
the sampling sheets. All samples are stored onsite
and delivered to the freight company depot at
Meekatharra by Horseshoe personnel for delivery
to Perth and the assay laboratory. Samples are
tracked and receipt is acknowledged by laboratory
staff.|

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 Horseshoe Lights Project comprises one Mining Lease (M52/743) and adjoining Exploration and Prospecting Licences covering an area of approximately 80 km2 (79,733 hectares). Current registered holder of the tenements is Murchison Copper Mines Pty Limited, a wholly owned subsidiary of Horseshoe Metals Limited. Horseshoe Metals Ltd has 100% interest in the tenements. Horseshoe Gold Mine Pty Limited retains a 3% Net Smelter Return royalty in respect to all production from some of the tenements including M52/743. The project has a current expenditure commitment of $187,500 per reporting year. Kopore has the right to earn a 51% beneficial interest in the area of 32.4km2 of land surrounding the Horseshoe Lights Mine over a two-year period. Stage one includes a minimum expenditure amount of $250,000 to be spent in year 1. |

The Horseshoe Lights Project was discovered in 1946 and commenced production shortly after. Mining under various owners, including Barrack Mines and Sabminco NL extended from 1946 to 1994, achieving a total of 3,299,120t @ 2.9g/t Au, 1.7% Cu, 27.5g/t Ag and 16g/t Hg. Most exploration has focussed on the immediate mining area, aiming to delineate further copper/gold resources along strike and at depth. All activities completed by Horseshoe Gold Mine Pty Ltd which was a wholly owned subsidiary of Barrack Mines Ltd between 1983-1991 and Sabminco NL between 1992-1995. Barrack Mines Ltd drilled 43 diamond holes for 15,353m, 638 Reverse Circulation holes for 55,343m and 19 channel samples for 520m between 1983 and 1989. Sabminco NL drilled 14 HQ & NQ diamond holes for 2672.25m and 108 Reverse Circulation holes for 9,244m between 1990 and 1993. Initial hole spacing was on a nominal spacing of 50 x 50m |

| Geology | Deposit type, geological setting, and style of mineralisation. |
The historic Horseshoe Lights copper-gold mine and associated tenements are located approximately 800 km north-northeast of Perth and 140 km north of Meekatharra. The Horseshoe Lights Project comprises seven tenements that cover an area of approximately 33 square kilometres. The deposit is hosted at the top of the Narracoota Volcanics (tholeiitic basalt grading up into Mg basalts), below the Thaduna Greywacke (a lower, 100 m thick greywacke with subordinate mudstone and an upper, thicker coarse sandstone, grit, and conglomerate unit. Both are members of the Glengarry Group, just to the south of the overlying Mesoproterozoic (1100 Ma) Bangemall Group. At the top of the Narracoota Volcanics there are weakly metamorphosed volcaniclastics represented by quartz-chlorite schist, quartz-eye tuffs and altered volcanics, capped by a prominent 1 to 2 m thick, poorly bedded chert (BIF) with magnetite, specular hematite and pyrite which often contains significant gold associated with the pyrite. Primary VMS mineralisation at Horseshoe Lights occurs in the core of a NNW trending and SE plunging parasitic anticline, that is overturned to produce intermediate SW dips on western limbs and steep SW dips on eastern limbs. The massive and disseminated sulphide envelope of the deposit itself is also SW dipping and plunging to the SSE (150o) and was likely folded. It sits within altered basalt and mafic volcaniclastic units along the contact with overlying felsic volcanic schist. The VMS mineralisation in the mine area is constrained by the tightly folded and sheared stratigraphy and appears to be affected by offsets along N-S and NE trending brittle cross faults. |

| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., cutting of high grades) and cut-off grades are usually Material and should be stated. |
Individual grades have been detailed in this press release and no averaging has been used to calculate multiple sample grade intercepts. |
| 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. |
No aggregation of samples has been conducted and detailed in Table 1. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No metal equivalent values have been stated in this press release. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
All drill intercepts have been reported as downhole lengths and not enough information is present to know the true widths of these intersections. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. |
The Horseshoe Lights open pit mineralisation geometry is well understood. The few significant intersections detailed in Table 1 have been drilled by RC technique and the geometry is yet to be fully understood. |
|
| 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’). |
The downhole lengths, true widths have been noted with Table 2 |
|
| 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. |
Refer to diagrams in body of text. |
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced avoiding misleading reporting of Exploration Results. |
The reported RC holes within the Kopore Agreement Area that contain a significant intercept, being intercepts over 1m in length with a gold grade of 0.5 g/t of gold or greater (Significant Intercepts) are reported. A total of 331 drillholes were drilled in the Agreement Area. Kopore has not included: • _251 drill holes that were not assayed for _ |

| either copper or gold; • 73 drill holes that were assayed for copper and gold but did not return a significant intercept. Kopore does not consider the: • 251 holes that were not assayed for copper of gold; • holes that or that did not return a Significant Intercept; or • intercepts that were not Significant Intercepts, to be material to the acquisition or Kopore's plans moving forward and has therefore not included these results in the announcement. |

| Other substantive exploration data |
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
