Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
- Section 1 Details for the Greenfields deposit reproduced from ASX Announcement “Measured Growth at the Greenfields Open Pit” Dated 5/08/2022
| Criteria | Explanation |
|---|---|
| Sampling techniques | • Focus Minerals Ltd (FML) RC percussion drill chips were collected at 1m intervals via a riffle splitter to achieve a sample weight of approximately 3kg. • For FML diamond core, sample intervals are either cut on metre intervals or with intervals selected to geological boundaries down to 10cm. Core is cut in half by diamond bladed saw with half sent to the laboratory and half retained in the core tray on site. Some of the diamond core has been ¼ core sampled, this is only in the minority of cases. • Coolgardie Gold NL (CGNL) collected 1m samples or 2m composites for RC holes, however, do not state their sub-sampling techniques. • CGNL diamond core was drilled at NQ size with an RC pre-collar. Half-core samples were selectively taken over 1m intervals. • Gold Mines of Coolgardie (GMC) collected 1m RC samples from surface. • MPI collected 1m RC cuttings and were then passed through a trailer mounted cyclone and stand-alone riffle splitter to provide a 4-6kg sample. • Diamond core was drilled at NQ2 size and after orienting and logging, was ½ core sampled over the entire length of alteration zones up to a maximum of 1.5m length. • The Redemption JV (RJV) established between companies Goldfan Ltd, Croesus Mining NL, Matador Mining and Focus Minerals collected 1m RC samples from a trailer mounted cyclone and riffle splitter to achieve a sample weight of 4-6kg. • Diamond core was NQ2 sized and ½ core sampled from 0.3m to a maximum of 1.5m. |
| Drilling techniques | • Drilling included in the Mineral Resource estimate include RC face sampling hammer or NQ size diamond core. All FML drill core was orientated by the drilling contractor using an Ezy-mark system. Most holes were surveyed upon completion of the drilling have either been surveyed by single-shot camera, electronic multi-shot (EMS) or Gyroscopic methods. |
| Drill sample recovery | • In recent FML drilling all RC samples are drilled dry wherever possible to maximize recovery, with water injected on the outside return to minimize dust. There have been no recovery or sample quality issues for the FML drilling RC chips or drill core. • Sample recovery has been recorded in the drill hole logs for the diamond holes drilled by CGNL with no recovery issues. Historic RC drilling recovery is not recorded. |
Page 14 of 78
| Criteria | Explanation |
|---|---|
| Logging | • FML drill holes were logged for the entire length of the hole. • All diamond core samples were orientated, marked into metre intervals and compared to the depth measurements on the core blocks. Any core loss was noted and recorded in the database. All core was logged for structure and geology using the same system as RC. The core was photographed wet and dry one tray at a time using a standardised photography jig. • All RC samples were geologically logged to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present. • Logging was qualitative; however, the geologists often record quantitative mineral percentage ranges. • Historic RC and Diamond holes have been logged at 1m intervals to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present. • Original drill logs have been viewed and used to validate data stored in acQuire for a majority of thepre-Focus drilling. |
| Sub-sampling techniques and sample preparation |
• FML diamond core samples were taken from half core or quarter core cut using an Almonte automatic core saw. The remainder of the core was retained in core trays. • RC samples were cone split to a nominal 2.5kg to 3kg sample weight. The drilling method was designed to maximise sample recovery and delivery of a clean, representative sample into the calico bag. • The samples were collected in a pre-numbered calico bag bearing a unique sample ID. Samples were crushed to 75μm at the laboratory and riffle split (if required) to a maximum 3kg sample weight. • FML samples have been assayed by ALS Chemex in Kalgoorlie or Perth using a 30g Fire Assay method with an AAS finish. • The assay laboratories’ sample preparation procedures follow industry best practice, with techniques and practices that are appropriate for this style of mineralisation. Pulp duplicates were taken at the pulverising stage and selective repeats conducted at the laboratories’ discretion. • The sample sizes were considered to be appropriate for the type, style and consistency of mineralisation encountered during this phase of exploration. • Analytical methods for gold analysis for much of the historical drilling are 25g – 50g Fire Assay method and 50g Aqua Regia completed at various laboratories in Kalgoorlie and Perth. |
| Quality of assay data and laboratory tests |
• The assay method and laboratory procedures were appropriate for this style of mineralisation. The fire assay technique was designed to measure total gold in the sample. • No geophysical tools, spectrometers or handheld XRF instruments were used. • Drilling completed by Focus is subject to rigorous quality control processes in the sampling process. Routine standards and “blanks” are inserted into the sample strings and monitored on return from the laboratory. Any failures by these control samples to be within the acceptable three standard deviation limits above and below the certified values results in a string of samples around the failed sample to be re-tested by the laboratory. • Regular reviews of the sampling were carried out by the supervising geologist and senior field staff, to ensure all procedures were followed and best industry practice carried out. • Very little in the way of quality control data is available from sampling of the historical drilling that currently defines the resource. In 2002 MPI resampled some of the CGNL diamond core with repeats showing high degree of grade variability with a slight upgrade in mean grade. • RJV inserted a certified standard and a field blank every 20 samples, whilst the ALS Chemex laboratory in Kalgoorlie inserted a blank or certified standard every |
Market Announcement | Page 15 of 78
| Criteria | Explanation |
|---|---|
| 20 samples and a duplicate every 10 samples. • Drilling by Focus aimed to confirm the geometry of the ore envelope and grade tenor encountered in historical drilling. |
|
| Verification of sampling and assaying |
• Significant intervals were visually inspected by company geologists to correlate assay results to logged mineralisation. • Primary data is sent in digital format to the company’s Database Administrator (DBA) as often as was practicable. The DBA imports the data into an acQuire database, with assay results merged into the database upon receipt from the laboratory. Once loaded, data was extracted for verification by the geologist in charge of the project. • Historic holes were validated against paper copies and WAMEX reports where possible. • No adjustments were made to any current or historic data. If data could not be validated to a reasonable level of certainty it was not used in any resource estimations. |
| Location of data points | • All co-ordinates and bearings use the MGA94 Zone 51 grid system. • FML drill collars were surveyed by DGPS base station instruments. • Most of the RC and diamond holes have down hole surveys by either Eastman single shot camera, Electronic Multi-shot or Gyroscopic methods. • CGNL used Surtron to carry out the downhole surveying. |
| Data spacing and distribution |
• Drilling has been conducted on 20m by 10 – 15m spaced grid on sections orientated across strike of the ore zone at an azimuth of either 020º or 200 º and at various dips. After mining commenced FML conducted RC Grade control drilling on a 10m x 10m staggered grid at different pit floor levels across the mineralisation, averaging 40m depth. Wider spaced drilling exists at depth up to as wide as 40m by 80m. |
| Orientation of data in relation to geological structure |
• Drilling was designed based on known geological models, field mapping, verified historical data and cross-sectional interpretation. • Drill holes were orientated at right angles to the strike of the deposit, with dip optimised for drill capabilities and dip of the mineralisation. |
| Sample security | • All samples were reconciled against the sample submission with any omissions or variations reported to FML. • Historic sample security is not recorded. |
| Audits or reviews | • Significant data validation was completed by consultants Hellmann and Schofield who completed a resource estimate in 2005. • A review of sampling techniques was carried out by rOREdata Pty Ltd in late 2013 as part of a database amalgamation project. Their only recommendation was to change the QA/QC intervals to bring them into line with the FML Laverton system, which uses the same frequency of standards and duplicates but has them inserted at differentpoints within the numbering sequence. |

| Criteria | Commentary | Commentary |
|---|---|---|
| Sampling techniques |
• This report relates to results from Reverse Circulation (RC) drilling and diamond core drilling. The information of sampling techniques below applies to the drill holes drilled by Focus Minerals (FML) only. • RC percussion drill chips were collected through a cyclone and cone splitter. Samples were collected on a 1m basis. Diamond core was sampled across identified zones of mineralisation by site geologists, the sample widths varied between a minimum of 0.2m and a maximum of 1m. • RC chips were passed through a cone splitter to achieve a sample weight of approximately 3kg. The splitter was levelled at the beginning of each hole using a bullseye level. The spoils were collected at 1m intervals. • 4m composite samples were taken by spear sampling the spoils. Where results returned greater than 0.2g/t Au, the 1m samples were submitted. • At the assay laboratory all samples were oven dried, crushed to a nominal 10mm using a jaw crusher (core samples only) and weighed. Samples in excess of 3kg in weight were riffle split to achieve a maximum 3kg sample weight before being pulverized to 90% passing 75μm. • The diamond core was marked up for sampling by the supervising geologist during the core logging process, with sample intervals determined by the presence of mineralisation and/or alteration. The core was cut in half using an Almonte automatic core saw. • Electrum submitted 1m RC samples for analysis. • Goldfan collected 2kg samples as either 4m composites or as 1m samples through mineralised ground or interesting geology. Samples were run through a cyclone. Where the 4m composite samples returned greater than 0.2g/t Au, 1m samples were submitted. Diamond core was sampled according to lithological boundaries. Mineralised zones were half diamond sawn in intervals generally not exceeding 1m. • MPI collected drill cuttings at one metre intervals which were passed through a trailer mounted cyclone and stand-alone riffle splitter to provide a 4-6kg split sample and a bulk residue for logging. All samples were dry. Initially samples were spear-sampled to form up to 5m composites and submitted for analysis. Any results above 0.5g/t Au resulted in the 1m samples then being submitted. |
|
| Drilling techniques | • All FML drilling was completed using an RC face sampling hammer or NQ2/HQ3 size diamond core. Where achievable, all drill core was oriented by the drilling contractor using an Ezy-mark system. Most holes were surveyed upon completion of drilling initially using an electronic multi-shot (EMS) camera and since Sept 2013 a north-seeking gyroscope; holes were surveyed open-hole prior to 2017. Since late 2016, all holes were surveyed using various gyroscopes (non-north-seeking paired with an azimuth aligner and north-seeking) by the drill contractors whilst drilling. • Goldfan used RC face sampling hammer or NQ2 diamond core drilling methods. The core was not orientated. Holes were downhole surveyed by Eastman single shot camera and later by Eastman multiple shot camera. MPI used RC drilling methods and downhole surveys by Eastman single shot camera. |
|
| Drill sample recovery |
• FML Sample recovery was recorded by a visual estimate during the logging process. • All RC samples were drilled dry whenever possible to maximize recovery, with water injection on the outside return to minimise dust. Goldfan states a consistent sample recovery in the range of 80-90% |
Market Announcement | Page 17 of 78
| Logging | • The information of logging techniques below applies to the drill holes drilled by FML only. All core samples were oriented, marked into metre intervals and compared to the depth measurements on the core blocks. Any loss of core was noted and recorded in the drilling database. • All RC samples were geologically logged to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present. • All diamond core was logged for structure, and geologically logged using the same system as that for RC. • The logging information was transferred into the company’s drilling database once the log was complete. • Logging was qualitative, however the geologists often recorded quantitative mineral percentage ranges for the sulphide minerals present. • Diamond core was photographed one core tray at a time using a standardised photography jig. • More recently samples from RC holes were archived in standard 20m plastic chip trays. • The entire length of all holes is logged. • Historic RC holes have been logged at 1m intervals to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present. • Goldfan logged diamond core to lithological boundaries, core was photographed. |

| Sub-sampling techniques and sample preparation |
• The information of sub-sampling and sample preparation below applies to the drill holes drilled by FML only. • Core samples were taken from half core, cut using an Almonte automatic core saw. The remainder of the core was retained in core trays tagged with a hole number and metre mark. • RC samples were cone split to a nominal 2.5kg to 3kg sample weight. The drilling method was designed to maximise sample recovery and delivery of a clean, representative sample into the calico bag. • Where possible all RC samples were drilled dry to maximise recovery. The use of a booster and auxiliary compressor provide dry sample for depths below the water table. Sample condition was recorded (wet, dry, or damp) at the time of sampling and recorded in the database. • The samples were collected in a pre-numbered calico bag bearing a unique sample ID. Samples were crushed to 75μm at the laboratory and riffle split (if required) to a maximum 3kg sample weight. Early FML composite samples were analysed for gold by a 40g aqua regia and then 40g Fire Assay for individual samples with an ICP-OES or AAS Finish. More recent Focus drilling used 40g Fire Assay with AAS finish for both composite and 1m samples. • The assay laboratories’ sample preparation procedures follow industry best practice, with techniques and practices that are appropriate for this style of mineralisation. Pulp duplicates were taken at the pulverising stage and selective repeats conducted at the laboratories’ discretion. • Earlier FML QAQC checks involved inserting a standard or blank every 10 samples in RC and taking a field duplicate every 20 samples in RC. Field duplicates were collected from the cone splitter on the rig. Diamond core field duplicates were not taken, a minimum of 1 standard was inserted for every sample batch submitted. In more recent drilling no blanks were submitted, only standards every 25 samples with a duplicate taken off the rig every 20th sample. • Regular reviews of the sampling were carried out by the supervising geologist and senior field staff, to ensure all procedures were followed and best industry practice carried out. • The sample sizes are considered to be appropriate for the type, style and consistency of mineralisation encountered during thisphase of exploration. |

| • Electrum submitted samples to SGS and Sertec in Kalgoorlie. Samples submitted to SGS were dried, jaw crushed, hammer milled, split and pulverised in Chromium Steel Mill. Assaying was by a 20g Aqua Regia digest and analysed by AAS. Sertec laboratory was found to have deficient lab practices with poor repeatability and SGS the preferred Laboratory. • Goldfan originally submitted its samples to Australian Laboratories Group Kalgoorlie. The 2kg samples were oven dried, then crushed to a nominal 6mm and split once through a Jones riffle splitter. A 1kg sub-sample was fine pulverised in a Keegor Pulveriser to a nominal 100 microns. This sample was homogenised and 400-500g split as the assay pulp for analysis. Assaying was by a classical fire assay on a 50g charge to a lower detection limit of 0.01 ppm gold. • Diamond core and later RC drilled by Goldfan was submitted to Minlab Kalgoorlie where the whole of the sample is pulverised in a ring mill before 300g sample is split as the assay pulp. Assaying was by fire assay on a 50g charge to a lower detection limit of 0.01 ppm gold. • Goldfan conducted inter-laboratory check sampling over approx. 10% of holes over the whole program with results found to be within acceptable limits. • Laboratory repeat checks were also run on the assay data. • MPI submitted their samples to Analabs in Perth for analysis for gold by 50g fire assay for a 0.01g/t detection limit. • Laboratory repeat checks were also run, it appears minimum 3 analysis checks run for most of the drill holes. |

|---|---|
| Quality of assay data and laboratory tests |
• The assay method and laboratory procedures were appropriate for this style of mineralisation. The fire assay technique was designed to measure total gold in the sample. • No geophysical tools, spectrometers or handheld XRF instruments were used. • The QA/QC process described above was sufficient to establish acceptable levels of accuracy and precision. All results from assay standards and duplicates were scrutinised to ensure they fell within acceptable tolerances. |
| Verification of sampling and assaying |
• Significant intervals were visually inspected by company geologists to correlate assay results to logged mineralisation. Consultants were not used for this process. • Normally if old historic drilling was present, twinned holes are occasionally drilled to test the veracity of historic assay data; however, no twinned holes were drilled during this program. • Primary data is sent in digital format to the company’s Database Administrator (DBA) as often as was practicable. The DBA imports the data into an acQuire database, with assay results merged into the database upon receipt from the laboratory. Once loaded, data was extracted for verification by the geologist in charge of the project. • No adjustments were made to any current or historic data. If data could not be validated to a reasonable level of certainty it was not used in any resource estimations. |
| Location of data points |
• FML drill collars were surveyed after completion, using a DGPS instrument. All drill core was oriented by the drilling contractor using an Ezy-mark system. Most holes were surveyed upon completion of drilling. Initially an electronic multi-shot camera was used until Sept 2013 when a north-seeking gyroscope tool was used. Holes were surveyed open hole prior to 2016. Since late 2016, most drill holes were surveyed using various gyroscope systems (non-north-seeking gyroscopes paired with azimuth aligners and north-seeking gyroscopes) by the drillers whilst drilling, otherwise surveyed open hole using a north-seeking gyroscope. Since the start of 2017, gyroscopes were used for “single shot” surveys whilst drilling, otherwise a single shot Eastman camera downhole survey was used. • All coordinates and bearings use the MGA94 Zone 51grid system. |

| Data spacing and distribution |
• Drill spacing along the Brilliant trend is approximately 20m x 20m through the main lode horizon, increasing to 20m x 40m and 40m x 40m to the north of 6573000mN. |
| Orientation of data in relation to geological structure |
• Drilling was designed based on known geological models, field mapping, verified historical data and cross-sectional interpretation. • Drill holes were oriented at right angles to strike of deposit, with dip optimised for drill capabilities and the dip of the mineralisation. |
| Sample security | • All samples were reconciled against the sample submission with any omissions or variations reported to FML. • All samples were bagged in a tied numbered calico bag, grouped into green plastic bags. The bags were placed into cages with a sample submission sheet and delivered directly from site to the Kalgoorlie laboratories by FML personnel on a daily basis. • Historic sample security is not recorded. |
| Audits or reviews | • A review of sampling techniques was carried out by rOREdata Pty Ltd in late 2013 as part of a database amalgamation project. Their only recommendation was to change the QA/QC intervals to bring them into line with the FML Laverton system, which uses the same frequency of standards and duplicates but has them inserted at different points within the numbering sequence. |

| Sampling techniques |
FML RC Sampling • Focus Minerals Ltd (FML) RC percussion drill chips were collected through a cyclone and riffle splitter. Samples were collected on a 1m basis. The spoils were either bagged per metre in appropriately sized plastic bags or placed on the ground and left in neat rows at 1m intervals with an accompanying cone split 1m calico sample FML Diamond Core Sampling • Diamond core was collected into standard plastic core trays. Down hole depths were marked onto wooden core blocks and stored in the trays. • The diamond core was marked up for sampling by the supervising geologist during the core logging process, with sample intervals determined by the presence of mineralisation and/or alteration. Whenever possible the cutline was drawn parallel to and close to the core orientation line to ensure the cutline was consistent over the hole. The core was cut using an automatic core saw, with half-core samples (NQ and HQ) and quarter core samples (PQ) submitted for analysis. • At the assay laboratory all samples were oven dried, crushed to a nominal 10mm using a jaw crusher (core samples only) and weighed. Samples in excess of 3kg in weight were riffle split to achieve a maximum 3kg sample weight before being pulverized to 90% passing 75μm. • Goldfan collected 2kg samples as either 4m composites or as 1m samples through mineralised ground or interesting geology. Samples were run through a cyclone and then put through a riffle splitter. Where the 4m composite samples returned greater than 0.25g/t Au, 1m samples were submitted. • Cord Holdings (Cord) collected 1m samples off the RC rig, split the samples by unknown methods and submitted them for assay. • Information on the seven Diamond holes drilled by Northland Minerals Ltd is limited and only referred to as an internal report on WAMEX. However, four of these holes were targeted within the current CNX pit. Samples were taken as predominantly 1m intervals, with 2m composites taken from surface to approx. 18m below surface. Samples were also taken to geological contacts. • Clackline Ltd (Clackline) drilled RC pre-collars followed by NQ drill core. The RC pre-collars were riffle split with 1m samples submitted for assay, while NQ core was sawn and ½ core 1m samples submitted for analysis. |
| Drilling techniques | • Years 2020 onward FML RC drilling was conducted using a 5 3/8inch face sampling hammer for RC drilling. • At hole completion, downhole surveys for RC holes were completed at a 10m interval by using True North Seeking Gyro tool. Otherwise, a single shot Eastman camera downhole survey was used either “in-rod” or “open hole”. • Years 2020 onward FML diamond drilling core was drilled at NQ2/HQ3/PQ size. All drill core was oriented where competent by the drilling contractor using an electronic, accelerometer-based system. • At hole completion diamond holes were open hole surveyed using an electronic multi-shot (EMS) tool in single shot mode at a range of intervals between 20m and 50m on drilling advance, averaging 30m. • Year 2014 FML drilling was completed using an RC face sampling hammer or NQ2/HQ3 size diamond core. Where achievable, all drill core was oriented by the drilling contractor using an Ezy-mark system. Most holes were surveyed upon completion of drilling using an EMS camera open hole. • Goldfan used RC face sampling hammer. Holes were downhole surveyed by Eastman single shot camera and later by Eastman multiple shot camera. • Cord RC holes were completed using RC roller and hammer. • Clackline drilled RC pre-collars followed by NQ diamond core tails. Holes were downhole surveyed by Eastman single shot camera. |

| Sampling techniques |
• This report relates to results from Reverse Circulation (RC) drilling and diamond core drilling. The information of sampling techniques below applies to the drill holes drilled by Focus Minerals (FML) only. • RC percussion drill chips were collected through a cyclone and cone splitter. Samples were collected on a 1m basis. Diamond core was sampled across identified zones of mineralisation by site geologists, the sample widths varied between a minimum of 0.2m and a maximum of 1m. For the 2004 drill program at Bonnie Vale 4m composite samples were collected manually using spear sampling of green bags and submitted for assay. Where the RC composite samples returned an assay value of 0.2g/t Au or greater, the 1m cone-split samples were then submitted for analysis. • RC chips were passed through a cone splitter to achieve a sample weight of approximately 3kg. The splitter was levelled at the beginning of each hole using a bullseye level. At the assay laboratory all samples were oven dried, crushed to a nominal 10mm using a jaw crusher (core samples only) and weighed. Samples in excess of 3kg in weight were riffle split to achieve a maximum 3kg sample weight before being pulverized to 90% passing 75μm. The samples were then prepared for fire assay. • When visible gold was observed in RC chips, this sample was then flagged by the supervising geologist for the benefit of the laboratory. The diamond core was marked up for sampling by the supervising geologist during the core logging process, with sample intervals determined by the presence of mineralisation and/or alteration. The core was cut in half using an Almonte automatic core saw, with half-core samples submitted to Kalgoorlie assay laboratories for fire assay analysis by a 50g fire assay with an ICP-OES or AAS Finish. • Matador Exploration Pty Ltd (Matador) collected drill cuttings at 1m intervals and passed through a trailer-mounted cyclone and stand-along riffle splitter to provide a 4-6kg split sample and bulk residue for logging. 4m composites were taken by spearing the residue and submitted for assay and where results were returned above 0.2g/t, the 1m riffle split samples were submitted for analysis. • Coolgardie Gold NL (CGNL) does not state sampling techniques except commentary that 4m composites were used and resampled when assays returned 0.2g/t Au or greater. |
| Drilling techniques | • All FML drilling was completed using an RC face sampling hammer or NQ2/HQ size diamond core. Drill core was oriented by the drilling contractor using an Ezy- mark or electronic system were core conditions allowed.

This syncline presumably overlaid gabbro hosted mineralisation through the central parts of the now mined open pit. • The majority of the open pit is situated on the hangingwall of the unmineralized footwall shear zone. The hangingwall is composed predominantly of Three Mile Sill equivalent differentiated layered intrusion. The chill margin of the intrusion is dolerite. The central part of the intrusion comprises variable gabbro sub units including significantly mineralised G2 Gabbro unit. Gold Mineralisation • Mineralisation is hosted by a quartz vein stockwork that exploits a conjugate set of brittle-ductile fractures. The structural sets are dominantly: • Flat dipping to the south west and, |

| • steep dipping to the south west • The structural sets host Bucky quartz veins have accessory pyrrhotite and arsenopyrite sulphides and sometimes visible gold is observed. • Veins display crack seal textures and are commonly weakly wall rock laminated. • The wall rock to the veins is commonly bleached over 0.2 - 0-.4m intervals. |

| Drill hole Information | • Historic drilling information has been validated against publicly available WAMEX reports. Not all drill holes can be found referenced in the WAMEX reports. However, cross-checking of original drill surveys was verified against the database. Most of these holes were drilled in the excavated pit area and has been depleted from the reported resource.

Final grade control drilling at Greenfields will be completed in the period July to mid August 2022 with final results expected in the December quarter 2022. The final phase grade control program will extend the existing RC grade control throughout the area targeted by the V23 pit at approximatel~12m x 15m spacing. Once compiled the new grade control data will facilitate a final pre-mining grade control Mineral Resource estimate to be compiled. |

| Mineral tenement and land tenure status |
• All exploration was conducted on tenements 100% owned by Focus Minerals Limited or its subsidiary companies Focus Operations Pty Ltd. All tenements are in good standing. The Malinyu Ghoorlie 2017 and Maduwongga 2017 Claims cover the majority of the Coolgardie tenure. At this stage no Coolgardie claims have progressed to determined status. |
| Exploration done by other parties |
• Brilliant has been explored and mined by various parties over time. The first phase of mining is believed to have taken place in the early twentieth century and would have consisted of prospecting shafts and limited underground mining. Mines Department records document treatment of 60 tons of ore producing 6.97oz of gold up to 1935. No otherproduction is recorded. |

| • Open pit mining of the prospect commenced in the 1970’s with a number of parties processing ore through the Coolgardie State Battery. In 1980 a treatment plant was constructed at Brilliant by Tryaction Pty Ltd, who produced from an open pit. In the mid 1980’s Electrum NL bought into the project, forming a joint venture with MC Mining. They expanded the treatment plant and continued open pit mining in the Brilliant area. Recorded production by Electrum/MC Mining is 87,986 tonnes at 3.2 g/t Au for 9,000 ounces with a stripping ratio of 12.7:1 (Kirkpatrick, 1995). The project was subsequently purchased by Goldfan Limited (a wholly owned subsidiary of Herald Resources Ltd) in 1991 and incorporated into the Tindals Project. They initiated drilling programs which increased the known extent of mineralisation and completed further open cut mining to its present limits in the early 2000’s. Table 2 in the FML Combined Annual Report of 2008 states an estimated total production from Brilliant Pit of in excess of 1.1Mt @ 2.45g/t for 88,000 ounces. |

| Geology | • Regionally Brilliant lies on the western margin of the Archaean Norseman – Menzies Greenstone Belt within the Coolgardie Domain of the Kalgoorlie Terrane. • Host rocks at Brilliant are a sequence of Archaean basalts and ultramafics, which have been intruded by a suite of porphyry dykes (also described as granodiorites). The contacts of the porphyries and other intrusives host the bulk of the gold mineralisation at Brilliant South. The majority of mineralisation at Brilliant consists of a stock work of quartz/sulphide micro-veining and albitic alteration of porphyry dykes and adjacent units. Additional mineralisation exploits moderate ENE dipping fractures set and extends between contact hosted mineralisation. |

| Data aggregation methods |
• Mineralised intersections are reported at a 0.5g/t Au cut-off with a minimum reporting width of 1m for RC holes and 0.2m for diamond holes, composited to 1m. |
|---|---|
| Relationship between mineralisation widths and intercept lengths |
• Holes were drilled orthogonal to mineralisation as much as possible, however the exact relationship between intercept width and true width cannot be estimated exactly in all cases. |
| Diagrams | • Accurate plans are included in this announcement. |
| Balanced reporting | • Drilling results are reported in a balanced reporting style. • The majority of FML drill assay results used in this estimation are published in previous news releases. Historic drill hole results available on WAMEX. |
| Other substantive exploration data |
• There is no additional material exploration data to report at this time. |
| Further work | • The Transition Zone Exploration Target area will be drilled in the next 12 months • Updated metallurgical testwork will be completed during the first half of 2022 to confirm recovery using TMH plant and address conservative estimate used in the 2020 Coolgardie PFS refresh • Material Classification sampling and more detailed mine design work will also be progressed during the first half of 2022 in order to progress submission of mining proposals • The background mineralisation outside the shoots defined for the February 2022 Mineral Resource estimate will begin to be assessed by combination of initial draft resource estimation and follow up drilling as the Coolgardie Gold Project progresses towards return to production. |

- Section 2 Details for the CNX deposit reproduced from ASX Announcement “CNX Mineral Resource Update” Dated 24/11/2021
| Criteria | Commentary |
|---|---|
| Mineral tenement and land tenure status |
• CNX is located within Mining Lease M15/645, registered to Focus Minerals Ltd. and Focus Operations Pty Ltd of Perth, Western Australia and which is current until March 2035. • The Malinyu Ghoorlie 2017 and Maduwongga 2017 Claims overlap this resource area. |
| Exploration done by other parties |
• CNX and the adjacent Three Mile Hill deposits have been explored by numerous parties over the years. A 1986 Cord WAMEX report references the lease mentioned in 1947 Department of Mines Annual Reports. They also indicate earlier prospecting activity was evident by: • two shallow shafts • several shallow pits sunk within the mineralised dolerite belt. • large scale alluvial/elluvial surface mining by previous holders • More modern exploration of the deposit has involved various drilling campaigns by various drilling methods such as RAB, RC and Diamond since the mid 1960’s. • Geological mapping, trenching, ground magnetics, aeromagnetics and soil sampling have also been routinely carried out by other parties since the mid 1980’s. • Herald Resources briefly mined CNX in the 1990’s by open pit extraction while it was mining the adjacent Three Mile Hill deposit to the SE of the Great Eastern Highway. A 1.2Mtpa processing plant was constructed at the Three Mile Hill deposit. • The existing CNX pit is 275m long, 75m wide and has been mined to a depth of 30m. • The 1991 CNX OP produced 196Kt @ 1.86 g/t for 11,700oz targeting mineralisation exceeding 1 g/t.. Further to the south-east along the strike of the host G2 Gabbro is the Three Mile Hill OP. TMH OP has reported production of 4.2Mt at a grade of 2.4g/t Au for 324,116 ounces. |
| Geology | CNX • The CNX deposit mineralisation is located within the steeply southwest dipping and northwest striking Three Mile Hill Meta-gabbro. The Three Mile Hill Gabbro is a layered sill which includes a differentiated coarse grained granophyric quartz- hornblende granodiorite unit locally called “G2 Gabbro”. • The bulk of the quartz stockwork hosted mineralisation is developed within the G2 Gabbro. • Bulk style stockwork mineralisation is hosted by networks of 1 to +5cm quartz veins with general very shallow dips to the south-west. • Higher grade, generally 5 to +30cm laminated quartz veins, dip moderately to the south-east. • Together the two orientations of quartz vein stockworks have developed a bulk-style, tabular ore body at CNX within the G2 Gabbro. This mineralisation extends under the Great Eastern Highway and has been confirmed by drilling to be contiguous with the Three Mile Hill OP 190m to the south-east. • CNX deposit averages 35 to 45m width and outcrops/subcrops over more than 700m strike. • Infill and extensional drilling conducted since late 2020 has shown the mineralisation at CNX to be remarkably consistent and predictable with new drill holes beneath the indicated parts of the resource confirming potential for future resource expansion. CNX Gap Zone/Princess Midas • Recent drilling north of CNX OP has confirmed the location of the G2 Gabbro extending a further 190m to the NW before folding and extending an additional 400m to the west – southwest. |

Stockworks have been intersected between the north end of CNX and the fold nose over 190m strike. However, the tenor and width of the mineralisation declines in this area and it is now termed the “Gap Zone”. It is also noted the Gap Zone is crosscut by several north-west trending faults resulting in block faulting of the stratigraphy.
-
• Several shallow workings and a single significantly larger shaft are located at the north end of the Gap Zone, historically called “Princess Midas”. The workings have targeted some of the Gap Zone crosscutting faults and also the eastern margin of the fold hinge where the mine stratigraphy changes orientation and extends westsouthwest.

- Drilling has been conducted over 400m west-southwest strike of this fold limb targeting the now mapped G2 Gabbro. The drilling has extended a new zone of CNX bulk style mineralisation 400m to the west. This developing prospect has been named “Green Light”

| Relationship between mineralisation widths and intercept lengths |
• Holes were drilled orthogonal to mineralisation as much as possible, however the exact relationship between intercept width and true width cannot be estimated exactly in all cases. • 8 RC/DD holes have been drilled with dips toward the northwest, sub parallel and cutting across the G2 Gabbro. These holes were completed to test the resource model in areas being converted to Indicated status with holes planned to drill right across the host stratigraphy. This orientation while not perpendicular to the overall tabular mineralisation is in fact closer to orthogonal to the mineralised stockwork system developed within the host G2 Gabbro. |

| Mineral tenement and land tenure status |
• All exploration was conducted on tenements 100% owned by Focus Minerals Limited or its subsidiary companies Focus Operations Pty Ltd. All tenements are in good standing. • The Malinyu Ghoorlie 2017 and Maduwongga 2017 Claims overlap this resource area • Focus has in Principle permission from Coolgardie Shire to conduct exploration within the historic Bonnie Vale Townsite boundary and, for mining within 500m of the historic Bonnie Vale Townsite boundary as long as activities do not impact the historic Varischetti Mine Shaft |
| Exploration done by other parties |
• Bonnie Vale is the site of a number of historic workings including the “Varischetti Mine” (Westralia). Modern exploration has been conducted by Coolgardie Gold NL, Gold Mines of Coolgardie and FML. |
| Geology | • Locally the geology of the deposit is dominated by the Bonnie Vale Tonalite, with an ultramafic to the east and west of the tonalite. This ultramafic has been logged as a carbonate altered ultramafic and described as a komatiite in Hallberg’s regional mapping. Mineralisation is hosted within large (strike lengths >300m) quartz reefs which range in thickness from centimetre scale to several metres. The known reefs strike sub-parallel to the edge of the tonalite, with the main orientations being an easterly dip (e.g. Westralia) or northeast (Bonnie Vale, Quarry Reef) of 40 to 60 degrees |

| Criteria Explanation |
Criteria Explanation |
|---|---|
| Database integrity | • Data was geologically logged electronically; collar and downhole surveys were also received electronically as was the laboratory analysis results. These electronic files were loaded into an acQuire database by either consultants rOREdata or the company in-house Database Administrator. Data was routinely extracted to Microsoft Access during the drilling program for validation by the geologist in charge of the project. • FML’s database is a Microsoft SQL Server database (acQuire), which is case sensitive, relational, and normalised to the Third Normal Form. As a result of normalisation, the following data integrity categories exist: • Entity Integrity: no duplicate rows in a table, eliminated redundancy and chance of error. • Domain Integrity: Enforces valid entries for a given column by restricting the type, the format, or a range of values. • Referential Integrity: Rows cannot be deleted which are used by other records. • User-Defined Integrity: business rules enforced by acQuire and validation codes set up by FML. • Additionally, in-house validation scripts are routinely run in acQuire on FML’s database and they include the following checks: • Missing collar information • Missing logging, sampling, downhole survey data and hole diameter • Overlapping intervals in geological logging, sampling, down hole surveys o Checks for character data in numeric fields• The historical Greenfields drill data was validated by the Focus data management team and the Project Geologist. This involved collaborating all collar, downhole survey, geology and assay data with existing hardcopy material as well as displaying the holes in three dimensions in Surpac to determine any unusual or unlikely trends in the data so that it could be rectified before loading into the Focus site database. This process was thorough and took a couple of months for the team to complete. |
| Site visits | • Alex Aaltonen, the Competent Person for Sections 1 and 2 of Table 1 is FML’s General Manager - Exploration and conducts regular site visits. • Hannah Kosovich, the Competent Person for Section 3 of Table 1 is FML’s Resource Geologist and last visited site in February 2014. |
| Geological interpretation |
• Minor changes were made to the geological interpretation used in the July 2020 resource release were used for this mineral resource estimate and were constructed as follows: • All available drill hole, mining data and pit mapping was used to guide the geological interpretation of the mineralisation. • The mineralised geological interpretation was generated in Seequent Leapfrog Geo implicit modelling software. • A total of 29 lodes were modelled. Four larger, steeper dipping (55o to SSW) lodes were modelled, along with 25 less continuous, shallower dipping (30o to SSW) lodes. The shallower lodes intersect the steeper lodes near surface with the flatter lying structures given priority over the steeper dipping lodes. • Minor deviation of the lode geometry was modelled between drill holes down dip and along strike. |
Market Announcement | Page 55 of 78
| Criteria Explanation |
Criteria Explanation |
|---|---|
| Dimensions | • The resource extends over a NW strike length of over 480m and includes the ~150m interval from the base of the final mined surface down to the 150mRL, some 250m below surface. The thickness of the four steeper lodes varies from average thickness of 20m near surface pinching to an average thickness of 3m at depth. The flatter lying lodes vary from 1m to 8m wide have an average thickness of 3m. |
| Estimation and modelling techniques |
• An Ordinary Kriging (OK) estimate was run using Datamine software, following the process below: • Drill hole samples were selected within the mineralised lodes and composited to 1m downhole intervals, the dominant sample interval from historic drilling. Residual samples that did not meet the minimum length criteria (less than 0.2m) of the compositing process were appended to the adjacent sample so that all material within the wireframe was included. • The composited data was imported into Supervisor software for statistical and geostatistical analysis. • After a review of the individual lode statistics, higher Au samples that were outliers to the main population were “top-capped” to a selected value for each lode. An average of 10ppm Au was used with a maximum of 15ppm Au. • Variography was modelled on data transformed to normal scores, the variogram models were back transformed to original units before exporting. • Variography was performed on the individual lodes with larger sample numbers ~ 150 samples. Lodes without variography shared the structure from a nearby lode. • The back-transformed variogram models had moderate to high nugget effects (20 to 60% of total sill), with a range from 20m to 200m for the lodes. • Estimation (via Ordinary Kriging) was into a non-rotated block model in MGA94 grid, with a parent block size of 10 mE x 5 mN x 5 mRL – this is about the average drill spacing in the deposit. Sub-blocking was used to best fill the wireframes and inherit the grade of the parent block. No rotation was applied to the orientation of the blocks. • The ellipsoid search parameters used the variogram ranges, with a minimum of 8 and maximum of 16 samples per block estimate was used. After the first pass 76% of blocks had estimated. For un-estimated blocks after this first pass, the search distance was expanded by a factor of two and the minimum number of samples dropped to 4. In the second pass 22% of blocks estimated. A third pass was then run with an increased search distance by a factor of four and the same minimum number of samples. Only 2% of blocks estimated in the third search pass. • Where the four steep lodes intersected the flat lodes a “soft boundary” approach was taken, whereby samples were shared at the intersection up to 10m radius in the overprinted steep lodes. • The estimate was validated by visually stepping through the estimated blocks and sample data in Datamine. Comparing the estimated block statistics with composited sample data and generate trend (Swath) plots to ensure the estimate was honouring the trends of the data. Also, a review of the output parameters from the estimation process like kriging variance, negative weights, search distances and sample numbers. |
| Moisture | • Tonnages are estimated on a dry basis. |
| Cut-off parameters | • The Resources for Greenfields have been reported above a 0.6g/t cut-off for the V23 open pit design. |
| Mining factors or assumptions |
• An existing open pit exists at Greenfields, mining would continue by cut-back and open cut extraction. |
| Metallurgical factors or assumptions |
• Metallurgical testwork has been conducted on Greenfields samples: • Historical recoveries in a variety of tests (N=13) average more than 95%gold recovery. • Recent testwork to simulate processing at TMH on composite representative samples (n=2) from Greenfields delivered very high gravity gold recovery averaging |
Market Announcement | Page 56 of 78
| Criteria Explanation |
Criteria Explanation |
|---|---|
| 70.5% and overall average gold recovery exceeding 93.5% • MPI who mined Greenfields from Dec 2003 to Jan 2005 had an overall reconciliation of ~96.9% of tonnes, 100.7% of grade and 101% of ounces milled compared to mined. |
|
| Environmental factors or assumptions |
• Greenfields deposit occurs in an area of previous disturbance with an open cut pit and associated waste dump. • The Three Mile Hill Processing Plant is currently on care and maintenance, but has all the necessary tailing facilities etc, that would allow for a restart of the plant. |
| Bulk density | • Bulk density test work was carried out on diamond core samples using a water immersion method for these determinations. • Average bulk densities were applied to modelled weathering profiles. • Bulk densities of 2.07, 2.43 and 2.87 t/m³ were applied to Oxide, Transitional and Fresh resources, respectively. |
| Classification | • Mineral Resources have been classified as either Measured or Indicated based mainly on geological confidence in the geometry and continuity of the lodes. In addition, various estimation output parameters such as number of samples, search pass, kriging variance, and slope of regression have been used to assist in classification. • Measured resources have been reported inside the 2022 V23 pit design. • Indicated resources have been reported outside to the V23 open pit using preliminary small scale underground cut-off grade of 2.3 g/t Au. |
| Audits or reviews | • No external audits of the mineral resource have been conducted. |
| Discussion of relative accuracy/ confidence |
• The mineral resource relates to global tonnage and grade estimates. |

| Database integrity | • FML data was geologically logged electronically, collar and downhole surveys were also received electronically as were the laboratory analysis results. These electronic files were loaded into an acQuire database by either consultants rOREdata or the company in-house Database Administrator. Data was routinely extracted to Microsoft Access during the drilling programs for validation by the geologist in charge of the project. • FML’s database is a Microsoft SQL Server database (acQuire), which is case sensitive, relational, and normalised to the Third Normal Form.

| Geological interpretation |
• All available drill hole and pit mapping data was used to guide the geological interpretation of the mineralisation. • Drilling by FML from 2018 to 2021 confirmed and added to the mineralisation interpretation from the June 2017 mineral resource estimate. • The host rocks at Brilliant are a sequence of Archaean basalts and ultramafics, which have been intruded by a suite of porphyry dykes (also described as granodiorites). The porphyries host the bulk of the mineralisation, occurring in two orientations, steeply dipping to the east (70 - 80°) with an average width of 3 to 5 m, or flatter dipping (20 - 40°) with widths of up to 2 m. Mineralisation consists of a stockwork of quartz / sulphide micro-veining and albite alteration of the porphyry. • Mineralised shoots in the host rocks were defined at about a 0.3 to 0.5 g/t Au cut off, with these domains consistent with the geology. Higher-grade sub-domains within these shoots forming sets of coherent north-plunging mineralised lodes were also used. • The mineralised shoots strike to the NW in the northern east part of the deposit, and to the NNE in the central part of the deposits and towards the SSW in the southern part of the deposit. • There are five groups of mineralised shoots, each containing four to nine discrete lodes. |
| Dimensions | • The Brilliant mineralisation has been modelled over 2 km strike length, the shoots have been interpreted from surface to approximately 600 m below surface (~ -180 mRL). |
Market Announcement | Page 58 of 78
| • The main mineralised shoots vary in width from 2 to 20 m in width, with an average of 5 m. smaller shoots on the hanging wall (east) of the main zone have a strike length of few hundred metres, with average widths of 3 to 4 m. |
|
|---|---|
| Estimation and modelling techniques |
• Estimation of the mineral resource was by Ordinary Kriging (OK) using Datamine software, with the process as follows: • Drill hole data was selected within mineralised domains and composited to 1m downhole intervals – 1m is the dominant raw sampling interval. • The composited data was imported into Supervisor software for statistical and geostatistical analysis. • Variography was done on data transformed to normal scores, and the variogram models were back-transformed to original units. Variography was performed for the largest shoot within each of the five groups, and this variogram model was used for the other shoots in the group. • There is little difference in the Au grade distribution (mean and coefficient of variation (CV)) between the fresh and transitional material types, and few samples in the oxidised zone for most shoots, so all oxidation states were treated as a single estimation domain per shoot. • The back-transformed variogram models had low to moderate nugget effects (20 to 50% of total sill), with a ranges of up to 250 m in the main zone to 20 m in the smaller lodes. • Estimation (via Ordinary Kriging) was into a non-rotated block model in MGA94 grid, with a parent block size of 10 mE x 10 mN x 5 mRL – this is about the half average drill spacing in the deposit. • The ellipsoid search parameters were slightly shorter than the variogram ranges for each group of mineralised shoots. A minimum of 8 and maximum of 20 samples per block estimate was used. The search pass was expanded by a factor of two if the first pass did not estimate a block, and by a factor of four if a third pass was required. For the main high-grade shoots, 80 to 95% of the blocks were estimated on the first pass. • A ‘distance limited threshold’ technique was used where uncapped data was used within 5 m of the extreme values, but a capping was used beyond this. The caps were variable per shoot and were based on inflections and discontinuities in the histograms and log-probability plots. The highest cap was 20 ppm Au for the main high-grade shoot, with most other high grade shoots having caps between 8 and 15 ppm Au. • Estimates of Au grades were validated against the composited drill hole data by extensive visual checking in cross-section, plan and on screen in 3D, by global comparisons of input data and model, and by semi-local statistical methods (swath plots). All methods showed satisfactory results. |
| Moisture | • Tonnages are estimated on a dry basis. |
| Cut-off parameters | • The Resources for Brilliant have been reported above a 0.5 g/t cut-off for open cut above 230 mRL, and above a 1.5 g/t cut-off for underground resources below the 230 mRL. This represents a reduction in reporting cut-off grade for the open cut resources from 0.7 g/t to 0.5g/t compared to June 2017. The changes have been made by the application of a simple economic mode (in Australian dollars): • Gold price of $2500/oz., Processing and G&A costs of $35/tonne, Processing recovery of 95%. • Open cut mining costs $3.50/tonne, underground mining costs $80/tonne. |
| Mining factors or assumptions |
• The upper part of the Brilliant deposit would be mined by conventional open-cut methods. Pit optimisations and designs using preliminary wall angles and PFS inputs (including conservative gold price of AUD $2,200/oz.) were run in September 2020 indicating potential for open pit extraction to 180 m depth (i.e., 230 mRL). • Geotech for Brilliant has been developed to feasibility level and indicates that the wall rock for the pit design is competent and support moderately steep wall angles and thereby expanded pit optimisation/economic pit designs • Previous mining at Brilliant in the 1990’s and early 2000’s was successful, with over 1.1 Mt for almost 90,000 ounces extracted. • The width of mineralisation from surface and overall steep mineralised sill geometry supports extendedpit optimisation and designs. |
Market Announcement | Page 59 of 78
| • Below 180 m depth, the high-grade shoots are steeply dipping consistent and coherent zones that would be amenable to long hole stoping mining methods. |
|
|---|---|
| Metallurgical factors or assumptions |
• Historical open cut mining at Brilliant was successful, with almost 90,000 ounces recovered by Herald Resources. • Metallurgical test work for Brilliant has been conducted over several periods between 1984 and 1998 using a variety of methods including: • direct cyanide leach • gravity followed by cyanide leach • gravity followed by floatation and leach. • Given the proposed processing of Brilliant ore at the Three Mile Hill Plant, test work comprising gravity recovery followed by leach is most representative recovery method. • In December 1996 Ammtec Ltd conducted metallurgical test work on 2 composite samples from Brilliant (TNG1166, 37-38m and 43-44m. Grade: 1.49 ppm) and (TNG1167, 26-27m and 29-30m. Grade: 3.35 ppm). Work carried out included detailed elemental analysis, grind establishment, gravity separation/cyanidation and gravity separation/floatation/cyanidation test work. Excellent overall gold recoveries were reported for the gravity/cyanide leaching test work with 97.75% for Composite 1 and 95.51% for Composite 2. • For the purposes of the 2017 and follow up 2020 Coolgardie PFS, metallurgical recovery using the Three Mile Hill plant was conservatively discounted by 5% and assumed to be 90.5%. • New test work is proposed for the Brilliant deposits which now include substantially more ore tonnes reporting above 0.5 g/t cut off. |
| Environmental factors or assumptions |
• The Brilliant deposit occurs within an area of significant previous ground disturbance including: • the previously mined pit is almost 1 km long and is over 70 m deep • large scale alluvial/eluvial washing plants • shafts/ trenches • the deposit is located 3 km south of the Three Mile Hill ROM pad. • The flora and fauna in the Brilliant area was assessed in 2013 as part of a mine proposal developed at that time. No significant habitats were identified at that time. • During 2021 an updated and expanded biological study was progressed with final results expected in 2022. This study has not identified at this time any threatened or priority taxa in the survey area. |
| Bulk density | • Density values were assigned based on lithology type and weathering profile. Diamond core was used for water immersion technique density test work, and there is an extensive data set of more than 700 determinations. • Bulk density values varied from 1.66 to 2.0 t/m3 for oxidised, from 2.69 to 2.81 t/m3 for transitional material and from 2.84 to 2.94 t/m3 for fresh rock. |
| Classification | • Resources have been classified as Indicated and Inferred based mainly on geological confidence in the geometry and continuity of the mineralisation and close spaced (20m x 10m) drilling across the bulk of the deposit. In addition, various estimation output parameters such as number of samples, search pass, kriging variance, and slope of regression have been used to assist in classification. • Mineral classification strings in long section (N-S) were digitised to create continuous classification volumes. Material within the mineralised shoots, with a drill spacing of 20 mN x 20 mE or closer was classified as Indicated. Blocks inside the mineralised shoots that were not Indicated but within 20 to 40 m of drilling were classified as Inferred. The average drill spacing for the Inferred is 40 mN x 40 mE and up to 60 mN x 60 mE. |

| Database integrity | • FML data was geologically logged electronically, collar and downhole surveys were also received electronically as was the laboratory analysis results. These electronic files were loaded into an acQuire database by either consultants rOREdata or the company in-house Database Administrator. Data was routinely extracted to Microsoft Access during the drilling program for validation by the geologist in charge of the project. • FML’s database is a Microsoft SQL Server database (acQuire), which is case sensitive, relational, and normalised to the Third Normal Form. As a result of normalisation, the following data integrity categories exist: • Entity Integrity: no duplicate rows in a table, eliminated redundancy and chance of error. • Domain Integrity: Enforces valid entries for a given column by restricting the type, the format, or a range of values. • Referential Integrity: Rows cannot be deleted which are used by other records. • User-Defined Integrity: business rules enforced by acQuire and validation codes set up by FML. • Additionally, in-house validation scripts are routinely run in acQuire on FML’s database and they include the following checks: • Missing collar information • Missing logging, sampling, downhole survey data and hole diameter • Overlapping intervals in geological logging, sampling, down hole surveys • Checks for character data in numeric fields. • Data extracted from the database were validated visually in GEOVIA Surpac software and Seequent Leapfrog software. Also, when loading the data any errors regarding missing values and overlaps are highlighted. • Historic data has been validated against WAMEX reports where possible. |

| Geological interpretation |
• All available drill hole and pit mapping data was used to guide the geological interpretation of the mineralisation. • Further drilling by FML in 2021 confirmed the mineralisation interpretation from the June 2021 mineral resource update for CNX. • The CNX deposit mineralisation is located within the steeply southwest dipping and northwest striking Three Mile Hill Meta-gabbro. The Three Mile Hill Gabbro is a layered sill which includes a differentiated coarse grained granophyric quartz- hornblende granodiorite unit locally called “G2 Gabbro”. • The bulk of the quartz stockwork hosted mineralisation is developed within the G2 Gabbro. • Bulk style stockwork mineralisation is hosted by networks of 1 to +5cm quartz veins with general very shallow dips to the south-west. • Higher grade, generally 5 to +30cm laminated quartz veins, dip moderately to the south-east. • Together the two orientations of quartz vein stockworks have developed a bulk-style, tabular ore body at CNX Main within the G2 Gabbro. This mineralisation extends under the Great Eastern Highway and has been confirmed by drilling to be contiguous with the Three Mile Hill OP 190m to the south-east. |
Market Announcement | Page 62 of 78
| • Au grade envelopes were constructed in Seequent Leapfrog Geo software, using the two sets of quartz vein orientations described above and the overall gabbro sill geometry (striking northwest with a sub-vertical dip) as structural trends. • The economic compositing function in Leapfrog was used to generate the grade shells – a cut-off of 0.1 ppm Au was used to separate the mineralised and non-mineralised material. The composites were to 4 m downhole, with maximum allowable internal dilution of 2 m. • The final Au grade shells were constrained to within the G2 gabbro sill. |
|
|---|---|
| Dimensions | • The CNX – Three Mile Hill trend strikes NW – SE over 1.6km • The reported CNX resource has been truncated using the Great Eastern Highway as a divide and only the northern portion of the resource is reported. • The CNX mineralisation has been modelled over 800m strike length, the lodes have been interpreted from near surface to approximately 250m below surface to the 175mRL (deeper mineralisation. • Mineralisation averages 35-50m width over the strike length of the sill currently defined by drilling |
| Estimation and modelling techniques |
• Estimation of the mineral resource was by the non-linear method Localised Uniform Conditioning (LUC) using Isatis software. • The LUC estimation process was as follows: • Drill hole data was selected within mineralised domains and composited to 1m downhole intervals in Datamine software – 1m is the dominant raw sampling interval. • The composited data was imported into Isatis software for statistical and geostatistical analysis. • Variography was done on data transformed to normal scores, and the variogram models were back-transformed to original units. The Gaussian anamorphosis used for the normal scores transform was also subsequently used for the discrete Gaussian change of support model required for Uniform Conditioning. Variography was performed for single mineralised domain – oxidised was combined with the transitional/fresh rock as the oxidation later is very thin, with few samples.. • The back-transformed variogram model had a high nugget effect (~70% of total sill), with a range of 30 m. • Estimation (via Ordinary Kriging) was into block model that was a non-rotated model in MGA94 grid, with a panel block size of 20 mE x 20 mN x 5 mRL – this is about the average drill spacing in the deposit • A ‘distance limited threshold’ technique was used where uncapped data was used within 10 m of the extreme values, but a capping of 15 ppm was used beyond this This cap was based on inflections and discontinuities in the histograms and log- probability plots. • The ellipsoid search parameters were longer than the variogram ranges in order to estimate at the edges of the domain (100 m x 100 m x 30 m). A minimum of 10 and maximum of 20 samples per panel estimate was used, which effectively reduces the search ellipse in the well drilled areas to two or three drilling lines (~20 m to 40 m). • The grade distribution for the panels was into Selective Mining Units (SMU) block of 5 mE x 5 mN x 2.5 mRL (32 SMUs per panel) via the Uniform Conditioning (UC) technique. • The UC process applies a Change of Support correction (discrete Gaussian model) based on the composite sample distribution and variogram model, conditioned to the Panel grade estimate, to predict the likely grade tonnage distribution at the SMU selectivity. • The Localising step was then run, and the resulting SMU model was exported from Isatis to Datamine, with statistical validation to ensure consistency between software packages. • Estimates of Au grades were validated against the composited drill hole data by extensive visual checking in cross-section,plan and on screen in 3D, by global |

| comparisons of input data and model, and by semi-local statistical methods (swath plots). All methods showed satisfactory results. |
|
|---|---|
| Moisture | • Tonnages are estimated on a dry basis. |
| Cut-off parameters | • The Resources for CNX have been reported above a 0.5g/t cut-off for open pit above 200mRL (~230m depth). This represents a reduction in reporting cut off grade from 0.7 g/t to 0.5g/t compared to June 2021. This change has been made as: • the bulk style mineralisation is very consistent above 0.5g/t and, • 0.5 g/t is above the economic cut off expected for this style of orebody based on the 2020 PFS Update for Coolgardie open pits. |
| Mining factors or assumptions |
• The CNX deposit would be mined by open-cut methods. Pit optimisations using preliminary wall angles, PFS inputs and the updated 2021 resource have been run during June -September 2021 indicating potential for open pit extraction to 200m depth. • New drilling reported in this announcement has extended significant mineralisation to at least 230m depth that can now be assessed for pit optimisation and design • Geotech for CNX has been developed to feasibility level and indicates that the wall rock for the CNX pit design is competent and support moderately steep wall angles and thereby expanded pit optimisation/economic pit designs • The CNX mineralisation is largely intact with only a very small trial pit mined previously in 1991. • The width of mineralisation from surface and overall steep mineralised sill geometry supports extended pit optimisation and designs. |
| Metallurgical factors or assumptions |
• Historic mining at CNX has focussed on the alluvial and oxide portion of the mineral resource. • Pre 1990’s limited metallurgical test work indicates encouraging recoveries from oxide samples. • FML conducted metallurgical test work on three composite/representative fresh rock CNX samples collected in April/May 2021 with results received in August 2021. The Metallurgical testwork further confirmed high gravity gold recoveries indicated by historic sampling and very high leach recoveries with limited reagent consumption • A trial pit was excavated at CNX by Goldfan in 1991 using a 1 g/t cut off. Reported recovered gold for the trial mining exercise is 196kt @ 1.86g/t for 11,720 ounces. Reporting the November 2021 CNX resource within the trial pit generated 278kt @ 1.7g/t for 15,000 ounces above a 1g/t cut-off. • CNX is along strike of the Three Mile Hill open pit and part of the same system. Three Mile Hill OP has historical production of 4.2Mt at a grade of 2.4g/t Au for 324,116 ounces. |
| Environmental factors or assumptions |
• The CNX deposit occurs within an area of significant previous ground disturbance including: • the existing 270m strike and 30m deep 1991 CNX pit, • large scale alluvial/elluvial washing plants, • shafts/ trenches. • the deposit is located just 1.25km north of the Three Mile Hill ROM pad. • The flora a fauna in the CNX area was assessed in 2013 as part of a mine proposal developed at that time. No significant habitats were identified at that time. • The CNX Flora & Fauna survey will be updated in Spring 2021 • The southern margin of the reported Mineral Resource has been truncated 97m north of great Eastern Highway which is seen as a reasonable break between what is considered CNX to the northwest and Three Mile Hill Mineral Resource (not being reported here) to the southeast. |
| Bulk density | • Density values were assigned based on weathering profile. CNX has a very shallow weathering profile and the bulk of the deposit occurs in Fresh Rock. The diamond core from the 2020 and 2021 drill campaigns were used for water immersion |

| technique density test work. Averages from the extensive testing were applied based on updated weathering surfaces. • A value of 1.85 t/m3 was applied to oxide blocks, 2.70 t/m3 was applied to transitional material blocks and a value of 2.99 t/m3 applied to Fresh Rock. • Follow up down hole in situ density logging was completed in 2021 to validate the large water immersion bulk density dataset. The down hole data indicates the currently assigned fresh rock bulk density values may be ~10% conservative. |
|
|---|---|
| Classification | • Resources have been classified as Measured, Indicated and Inferred based mainly on geological confidence in the geometry and continuity of the mineralisation and close spaced (20m x 10m) drilling across the bulk of the deposit. In addition, various estimation output parameters such as number of samples, kriging variance, and slope of regression for the various kriging runs have been used to assist in classification. • The block model, drilling data and geological wireframes were loaded and mineral classification wireframe solids were created. Material within the mineralised domain, with recent (2020 / 2021) FML drilling and with a drill spacing of 20 mN x 10 mE or closer was classified as Measured. The Indicated wireframe is outside the Measured area, and encapsulates areas where drilling is at 20 mN x 20 mE. Blocks inside the mineralised domain, that were not Indicated or better but supported by FML drilling were classified as Inferred. • Sub-Inferred blocks exist at depth where drill spacing increases and south of the Highway exclusion zone. These are not included in the reported Mineral Resource Estimate and the areas at depth are future exploration targets. |
| Audits or reviews | • No independent audits or reviews of the November 2021 mineral resource estimate have been conducted. |
| Discussion of relative accuracy/ confidence |
• This is addressed in the relevant paragraph on Classification above. • The Mineral Resource relates to global tonnage and grade estimates. • The 1991 trial pit targeted +2 g/t mineralisation at CNX using a 1 g/t cut off. Actual mined material was 36% above the targeted diluted ore with ounces up 42%. Detailed mining reports are yet to be located in the mine archives to cross reference planned pit design vs actual mined pit. As such at this stage we are unable to validate if the difference between the pre mining resource estimate and actual mining was down to problems with resource estimation or simply that a larger pit was mined as a result of strong results. • The FML resource within the trial pit is of a similar grade when cut at 1 g/t to that reported post 1991 mining. However, the November 2021 resource reports more tonnes and ounces than were mined in 1992. This difference is likely due to selective mining during the 1991 trial mining exercise given the pre mining resource estimate appears to have targeted mineralisation exceeding 2 g/t. |

| Geological interpretation |
• All available drill hole and historic mining data was used to guide the geological interpretation of the mineralisation. • Historic underground works at Bonnie Vale have focused on extracting mineralised quartz reefs dipping at a 40°-45° angle. • This current interpretation of an un-excavated quartz reef at Bonnie Vale also supports mineralised quartz veins dipping at 40°-45°. • The mineralised geological interpretation was digitized in GEOVIA Surpac software on a section by section basis. An approximate 0.5g/t cut-off was used, infrequently sub 0.5g/t samples (logged as quartz veining) included for continuity. • Minor deviation only of the lode geometry was noticed between drill holes along strike and down-dip. • Minor lodes with less continuity and sample numbers were also interpreted. • Modelling of host rock and surrounding geology units in Seequent Leapfrog Geo implicit modelling software was used to guide the mineralisation interpretation with mineralised lodes confined to the Granodiorite. |
| Dimensions | • The main Quarry Reef lode extends east south east over a strike length of 500m and extends from about a depth of 70m below surface to approximately 550m below surface. The thickness of the main Quarry Reef lode varies from 2m to approximately 10m, with an average thickness of 4m. |

| Estimation and modelling techniques |
• Within the main mineralised lode, a ‘core’ domain of higher Au values closely associated with the quartz veining was interpreted. The boundary between the high-grade core and surrounding main mineralisation envelope was considered a hard boundary and no samples were shared between the two domains. The use of these domains controlled the limit of the high gold values encountered at Bonnie Vale. • Only RC and Diamond holes were used in the Estimation. In total 61 RC holes, 1 Diamond and 16 RC pre-collar with diamond tail holes (RC/DD) were used. • The drill hole samples were composited to 1m within each domain. This is the dominant sampling interval. • Composited assay values of each domain were exported to a text file (.csv) and imported into Snowden Supervisor and Geovariances Isatis software for geostatistical analysis. • A review of histograms, probability plots and mean/variance plots for each domain revealed some outlier sample values. • Top capping of higher Au values within each domain was carried out with Au values above the cut-off grade reset to the cut-off grade. • For the main core lode, a top cap of 40g/t was applied, while 15g/t was used for the surrounding domain. Different caps were used for the other minor lodes. • Directional variograms were modelled on the main Quarry Reef lode, without the higher-grade core samples. A Normal Scores transformation was applied to the data set for the surrounding to obtain variograms that could be modelled. A back- transformation was applied before exporting the variograms in a Surpac readable format. This variogram was also used for the minor lode domains, with minor orientation differences as required. For the core high-grade domain, the variogram was modelled in Isatis on capped but non-transformed data. • GEOVIA Surpac Software was used for the estimation. An Ordinary Kriging (OK) technique was selected using the variograms modelled in Supervisor/Isatis. Each domain was estimated separately using only its own sample values. No samples were shared between domains (hard boundaries). • Minimum (10) and maximum (24) sample numbers were selected based on a Kriging Neighbourhood analysis in Supervisor. • An elliptical search was used based on range of the Variograms (see table below). • Three search passes were run in order to fill the majority of the block model with estimated Au values. • Block sizes for the model were 10m in Y, 10m in X and 5m in Z direction. Sub celling of the parent blocks was permitted to 2.5m in the Y direction, 2.5m in the X direction and 1.25m in the Z direction. Sub-blocking was used to best fill the wireframes and inherit the grade of the parent block. The block model was rotated 450 about the Y axis to orientate the blocks to better fill the NW trend of the mineralisation. • Block size is approximately ½ of the average drill hole spacing. • The estimate was validated by a number of methods. An initial visual review was done by comparing estimated blocks and raw drill holes. |

| • Tonnage weighted mean grades were compared for all lodes with the raw and top-capped drill hole values. There were no major differences. • Swath plots of drill hole values and estimated Au grades by northing, easting and RL were done for the core and surrounding main and showed that the estimated grades honoured the trend of the drilling data. • Historic mine production from Bonnie Vale was recorded as an average gold grade of 16.2 g/t, which is very close to the estimated grade of the high-grade core lode for this estimate (16.6 g/t Au). |
|
| Moisture | • Tonnages are estimated on a dry basis. |
| Cut-off parameters | • The Resources for Bonnie Vale have been reported above a 1.5g/t cut-off. This is based on a gold price of AUD $2,200/oz. • Operating costs considered include underground mining, transport to and processing at FML’s Three Mile Hill processing plant (10km away) and administration. • Operating costs are based on the results of a Preliminary Feasibility Study (PFS) completed by consultants Mining One in 2017, ASX release: Coolgardie PFS Summary and Ore Reserve Upgrade, 13 October 2017. |
| Mining factors or assumptions |
• The PFS assessed a range of mining methods and proposed the Quarry Reef at Bonnie Vale being underground mined from a decline access using open stoping with cemented rock fill. |
| Metallurgical factors or assumptions |
• One sample (BONC055, 140-141m. Grade: 9.66 g/t) was sent to ALS Metallurgy for gravity/cyanide leaching test. The results show that the gravity gold recovery was high, at ~68%., overall gold extraction was very high, at >99%, with a final leach tail grade of only 0.05 g/t Au. |
| Environmental factors or assumptions |
• The Quarry Reef occurs within the historic Bonnie Vale mining centre with previous ground disturbances including waste dumps and milling residues/tailings. • The PFS Environmental assumptions included the mine plan utilising all waste generated as mine fill. • A closure plan and fund exist for the mine. • The Three Mile Hill Processing Plant is currently on care and maintenance but has all necessary tailing facilities etc. that would allow for a rapid restart of the plant. |
| Bulk density | • A bulk density of 2.65 t/m3 was used for the mineralised lodes. Previously the laminated quartz veins were assigned an overly conservative value of 2.6 t/m3 This was an undercall compared to the database of measurements. A value of 2.6 t/m3 would be expected for a pure quartz vein. However, Quarry Lode mineralisation is hosted by laminated veins that include slivers of altered wall rock and the increase in density is warranted. • Footwall tonalite/granodiorite density was also updated to 2.65 t/m3 • Hanging wall Ultramafic was assigned a bulk density of 2.80 t/m3. • The water immersion technique was used for these determinations on half cut diamond core |
| Classification | • Resources have been classified as either Indicated or Inferred based mainly on geological confidence in the geometry and continuity of the lodes. In addition, various estimation output parameters such as number of samples, search pass, kriging variance, and slope of regression have been used to assist in classification. • Significantportions of the core and surrounding main lodes which were estimated |

| in the first search pass were classified as Indicated. In addition, one of the minor lodes that was very close to the main lode (Domain 4) and was supported by ample drilling was classified as Indicated. • The remainder of the core and main lodes were classified Inferred, as were some of the minor lodes with good continuity and numerous drill intercepts. Smaller domains based on a single drill hole intercept data or filled on the second or third search pass were assigned a ‘not classified’ code and are not included in the reported mineral resource estimate. |
|
| Audits or reviews | • Previous mineral resources released for Bonnie Vale have been reviewed by QG Australia including reviewed/critiqued FML’s work on the geological interpretation, assay QAQC information, estimation methodology and parameters, and estimate validation. |
| Discussion of relative accuracy/ confidence |
• This is addressed in the relevant paragraph on Classification above. • The Mineral Resource relates to global tonnage and grade estimates • Bonnie Vale has historic production from 1894 to 1911 with recorded production figures of 176,883oz at an average grade of 16.2 g/t, the grade matches well with this Mineral Resource estimate of the high-grade core (16.6 g/t Au). |

|---|---|
| Mineral Resource Estimate for conversion to Ore Reserves |
• Mineral Resource estimates were produced by FML for each of the three deposits included in the 2022 Coolgardie Open Pit Reserves. Details of the resources including Table 1 sections 1 – 3 can be accessed in the following ASX Announcements: ➢ “_Measured Growth at the Greenfields Open Pit” Dated 5/08/2022 ➢ “Brilliant South Mineral Resource Grows 29%” Dated 23/02/2022 ➢ “CNX Mineral Resource Update” Dated 24/11/2021 • “The block models for each deposit were the basis of the Mineral Resources_ reporting and were used to develop the Ore Reserve estimate. The block models included fields to characterise blocks by resource category and discriminate mine depleted parts of the deposits. For the purpose of the Ore Reserve estimate only indicated and measured resource categories were considered. In particular, inferred category blocks were assigned a grade of 0.00 g/t Au for selecting minable parts of the Mineral Resource in conjunction with maintaining 0.00 g/t Au grade for all blocks characterised as unclassified material. This ensured that Inferred material did not feature in the assessment of economic minability of the Mineral Resource. • Conversion of the Mineral Resource to an Ore Reserve was on the basis of a viable mine plan and engineering design interrogating the relevant resource model • Those parts of the Mineral Resource that were within proposed mine design were used as the basis for determining the Ore Reserve. As such the Ore Reserve estimate is a subset of the total Mineral Resource and not an addition to the total Mineral Resource. |
| Site visits | • Alex Aaltonen, the Competent Person for Sections 1 and 2 of Table 1 is FML’s General Manager of Exploration and Geology, conducts regular site visits. • Hannah Kosovich, the Competent Person for Section 3 of Table 1 for the Greenfields deposit is FML’s Resource Geologist and has conducted site visits in the past. • Mike Job , the Competent Person for Section 3 of Table 1 for the Brilliant and CNX Deposits works for Cube Consulting and has conducted site visits in the past. • Gary McCrae of Minecomp Pty and the Competent Person for Section 4 Table 1 of Coolgardie Gold Project Ore Reserve conducted site visits in early and mid 2022. The site visit did not reveal any matters that may materially affect the ability to declare an Ore Reserve. |
| Study status | • An updated PFS appropriate to the deposit types, mining methods and scale has been completed for the Greenfield, Brilliant South and CNX deposits. • Greenfields and Brilliant open pits were included in earlier 2017 PFS and follow up 2020 PFS Update. • The Ore Reserve leverages on the work of both external consultants and in-house knowledge to a determine a mine plan which is both technically achievable and economically viable • The 2022 Ore Reserve Estimate has been completed to a Pre-Feasibility level of confidence (+/- 25% accuracy) • Detailed open pit mine designs have been completed. • Project costs and parameters were either supplied by various consulting/contracting companies or supplied by Focus. |

| Cut off parameters | • Varying economic cut-off grades were applied according to weathering domain for each deposit. These diluted gold cut-off grades ranged from 0.59g/t to 0.80g/t depending on location and weathering domain. • The inputs used to estimate the revenue per gram of gold produced and ultimately the cut-off grade were:- Gold Price: A$2,200/oz 2.5% WA State Royalty Refining Charges • The cost inputs used to calculate the total operating costs per tonne of ore processed included: Grade Control Ore Haulage Ore Processing Ore/Waste Mining Cost Differentials • Other inputs used to determine the cut-off grade included: Processing Recovery Mining Dilution • The economic cut-off grades were calculated using the formula: 𝐌𝐢𝐧𝐢𝐧𝐠 𝐃𝐢𝐥𝐮𝐭𝐢𝐨𝐧 × 𝐓𝐨𝐭𝐚𝐥 𝐏𝐫𝐨𝐜𝐞𝐬𝐬𝐢𝐧𝐠 𝐂𝐨𝐬𝐭𝐬 (𝐏𝐫𝐨𝐜𝐞𝐬𝐬𝐢𝐧𝐠 𝐑𝐞𝐜𝐨𝐯𝐞𝐫𝐲 × (𝐒𝐞𝐥𝐥 𝐏𝐫𝐢𝐜𝐞−𝐒𝐞𝐥𝐥 𝐂𝐨𝐬𝐭) |
| Mining factors or assumptions |
• The Mineral Resource models were factored to generate a diluted Ore Reserve during the optimisation process. • Whittle software was utilised for the optimisation analysis of the Greenfields, CNX and Brilliant gold deposits. • Detailed, practical and workable open pit mine designs based upon the results of the optimisation analysis have been completed for each of the deposits. These designs formed the basis for the Ore Reserve estimate. • External geotechnical reports formed the basis for the pit slope inputs for each of the deposits • Mining dilution was applied as follows:- . Greenfields 20% at 0.00g/t regardless of regolith .CNX 5% at 0.00g/t regardless of regolith Brilliant Oxide – 10% at 0.00g/t Transitional – 15% at 0.00g/t Fresh – 20% at 0.00g/t • A 95% mining recovery factor was used regardless of deposit and weathering domain. • The pit designs incorporated allowances for minimum mining widths and were deemed practical and workable. • Technical work and data consolidation was performed by Mr Gary McCrae of Minecomp Pty Ltd. • In line with the findings of the 2020 PFS, open pit mining was considered to be the most appropriate method for mining the Greenfields, CNX and Brilliant South Mineral Resources. Further studies may assess the viability of the resource beneath the proposed pit however the current Reserve estimate does not consider this possibility. • A standard 90t dump truck fleet and matching excavator pairing was selected to be utilised for the material movement requirements throughout the life of the project. Standard ancillary machinery – grader, dozer and water cart round out the mining fleet. |
Market Announcement | Page 71 of 78
| • Block models were provided with appropriate resource categories’ and grade distribution. It was assumed that the model was a fair and reasonable representation of the resource. • A nominal minimum mining width of 20m was used in the assessment. • Blocks classified as inferred in the resource model were given a zero grade to ensure that the inferred material was not a determinant in the Reserve estimate. • Minimal infrastructure will be required given that the resources have been previously mined and are in close proximity to the Three Mile Hill processing plant, administration buildings and the town of Coolgardie itself. |

| Metallurgical factors or assumptions |
• FML owns the Three Mile Hill Mill (Care and Maintenance Status) that has previously successfully treated a range of ores from Coolgardie deposits. • FML have completed detailed CAPEX and OPEX estimated to refurbish this Mill to 1.2Mtpa capacity. These estimated have been independently verified by YEM who completed a refurbishment scope of work and cost estimate in March 2022. • Metallurgical testwork has been completed for each of the deposits and included in open pit Reserve Estimation: • Greenfields – New representative metallurgical testwork has returned average gravity gold recovery of 70.5% and overall gold recovery of 93.65%. • CNX – New representative metallurgical testwork has returned average gravity gold recovery of 74.6% and overall gold recovery of 94.9%. • Brilliant South –11 metallurgical samples and historic mill performance provides indicative processing recovery of 95.5%. Four new representative metallurgical samples are undergoing testwork with results expected in the September Quarter 2022. • For the purposes of open pit Ore Reserve Estimation mill process recovery for all open pits has been set at 92%. |
| Environmental | • All three open pits are located on mine licenses. Furthermore, each site is located in the vicinity of historic mine infrastructure including accesses, waste dumps, mine offices. • Waste dump designs have been advanced for each of the investigated open pits. • Additional base line studies including: waste material classification, flora, fauna, hydrogeological studies and heritage surveys have all been advanced in order to progress mine approvals. The Greenfield open pit mine proposal was approved in June 2022. • MON notification has been completed to DMIRS in June 2022 and will be active from 3rd August 2022 • The schedule requires expansion of the Three Mile Tails Facility. FML already have approval for the 3rd lift to this tails facility. Detailed geotechnical and engineering works have already been completed to advance this work during the June 2022 quarter. • The conversion of the Greenfields open pit to an in pit TSF will require additional approvals. Engineering and design work to enable conversion of the mined pit to an in pit TSF has been advanced in July 2022. The proposed site is surrounded on the north East and south west sides by existing TSF’s all of which have been extended above natural surface level. • It is expected that there will be no serious conditions or impediments to mining any of the three open pits. |
| Infrastructure | • The mine plan properly considers the infrastructure requirements for the proposed mining. • The current Three Mile Hill plant is on care and maintenance. The plant requires 9 months of refurbishment (including supply of long lead time items) to be refurbished to 1.2Mtpa capacity. • The refurbishment schedule and budget are being refined via early contractor involvement and investigation with MACA - Interquip. |
Market Announcement | Page 72 of 78
| Costs | • Capital costs have been estimated on the basis of budget quotes from suppliers and benchmarking similar operations. • Opex costs have been estimated on the basis of budget quotes and benchmarking. • Mill Capex and OPEX was supplied by FML who have completed detailed review of plant performance and modelling. Mill CAPEX and OPEX is being finalised to develop an EPC refurbishment contract August 2022. • Mining operating costs were estimated by Gary McCrae of Minecomp Pty Ltd and have been derived from cost data held in Minecomp cost databases. • No inflation or escalation was assumed in the modelling • No allowances were made for the content of deleterious elements beyond what is currently understood. • The study was assessed Australian dollars and is somewhat insensitive to exchange rate fluctuations. For those costs depending on exchange rates published rates at the time of the study were used. • Transportation charges for the gold and further refining charges have not been included as they are not considered significant. • A 2.5% royalty is applicable; however, a rate of 3% has been used to account for further administrative costs. |
| Revenue factors | • The head grade is derived from the Mineral Resource and Modifying factors as described above. • Revenue calculations were based upon detailed mine plans which incorporated provisions for mining dilution and ore loss. • It is assumed that gold doré will be sold at spot price to the Perth Mint, Western Australia. • A gold price of A $2,200/oz has been used for the Ore Reserve estimation. This price is consistent with medium term projections from reliable analysist and is significantly below the current gold price. FML used the Consensus Economics forecast for setting the gold price for the 2020 Coolgardie PFS and 2021 Laverton PFS. The Consensus Economics median 5 year forecast price in A $ is higher than the price used in the 2022 Coolgardie Ore Reserve Estimation. |
| Market Assessment | • Gold is readily saleable and requires no specific marketing or sales contract. • Gold is a precious metal and thus subject to price fluctuations due principally to market sentiment. • Gold doré will be sold to the Perth Mint, Western Australia as it is produced. • There are no known major gold producers expected to influence the supply of gold over the period of the project. • The gold price in Australian dollars has held sustained gains in recent years. • The 2022 Coolgardie Ore Reserve Estimation uses a fixed price forecast over the life of mine. The current long-term forecast price indicates that a higher metal price may be achieved over the life of the mine. |
| Economic | • All resources included have positive NPV’s. |
| Social | • FML has been and continues to be a significant contributor to the Coolgardie and Kalgoorlie Shires. Furthermore, when in production FML contributed significantly to community projects including the annual Coolgardie Day Festival. FML expects future employment opportunities for the Coolgardie and Kalgoorlie communities would be welcomed. • All proposed mining and Infrastructure areas lie within granted mining leases. • There are two competing Native Title claims in the study area and over the Greenfields, CNX and Brilliant South prospect areas. • No Native Title claims have progressed to determined status |
| Other | • Detailed geotechnical works have been conducted at all open pits since the 2020 |

| Coolgardie PFS update in order to ensure open pit ore reserves include more refined design parameters vs the 2020 Coolgardie PFS. • The hydrogeology at each pit has been reviewed with piezo holes installed and a hydrogeology model completed. Additional studies will be underway in the remainder of 2022. • Blasting studies have been advanced for the Greenfields and CNX deposits to feed into further mining and ore loss studies • The use of Greenfields pit as a tailing facility will need approval. However, given its location and the fact that this approach has been utilised in an adjacent pit, this approval is not seen as a material risk. • All the resources and proposed mining activity is located on mining leases held by FML. • There is a long history of mining evidenced at each of the deposits. There is no reason to believe that a license to operate will not be granted. |

| Classification | • The Proved Ore Reserve has been derived entirely from Measured Mineral Resource. • The Probable Ore Reserve has been derived entirely from Indicated Mineral Resource. • 46% of the open pit Ore Resources are classified as Proved. • It is the Competent Person’s view that the methods used for the purpose of Ore Reserve estimation provide a fair and reasonable estimate of the mineable parts of the Mineral Resources as it is currently understood. |
| Audits and Reviews | • No external audit has been completed to date on the current open pit Ore Reserve estimate. • Focus and Minecomp have completed an internal review of this open pit Ore Reserve estimate. |
| Discussion of relative accuracy/ confidence |
• The level of study carried out as part of this Ore Reserve estimation is to a Pre- Feasibility Study level (+/-25%). The relative accuracy of the estimate is reflected in the reporting of the Ore Reserves as per the guidelines re: modifying factors, study levels and Competent Persons contained in the JORC 2012 Code. • There is a degree of uncertainty associated with geological estimates. The Reserve classifications reflect the levels of geological confidence in the estimates. • There is a degree of uncertainty regarding estimates with regards to the impacts of natural phenomena including geotechnical assumptions, hydrological assumptions, and the modifying mining factors, commensurate with the level of study. The Competent Person is satisfied that the analysis used to generate the modifying factors is appropriate, and that a suitable margin exists under current market conditions to allow for the Ore Reserve estimate to remain economically viable despite reasonably foreseeable negative modifying factor results. • There is a degree of uncertainty regarding estimates of commodity prices and exchange rates, however the Competent Person is satisfied that the assumptions used to determine the economic viability are reasonable based upon current and historical data. • This statement relates to global estimates of tonnes and grade. • Sensitivity studies were carried out. Standard linear deviations were observed. The Project is most susceptible to fluctuations in the direct revenue drivers, namely gold price, gold grade and metallurgical recovery. Sensitivity to mining costs is less with the Project being least sensitive to processing costs. |

| Mineral Resource Estimate for conversion to Ore Reserves |
• Mineral Resource estimates were produced by FML for Bonnie Vale Underground deposits included in the 2022 Coolgardie Reserve Update. Details of the Bonnie Vale Underground Mineral Resource estimate are included Table 1 sections 1 - 3 and can also be accessed in the following ASX Announcement: ➢ “Bonnie Vale Mineral Resource Update” Dated 2/09/2020 • The block models for the Bonnie Vale underground deposit is the basis of the Mineral Resources reporting and were used to develop the underground Ore Reserve estimate. The block model included fields to characterise blocks by resource category. For the purpose of the Bonnie Vale Underground Ore Reserve estimate only indicated and measured resource categories were considered. • In particular, inferred category blocks were assigned a grade of 0.00 g/t Au for selecting minable parts of the Mineral Resource in conjunction with maintaining 0.00 g/t Au grade for all blocks characterised as unclassified material. This ensured that Inferred material did not feature in the assessment of economic minability of the Mineral Resource. • Conversion of the Mineral Resource to an Ore Reserve was on the basis of a viable mine plan and engineering design interrogating the relevant resource model. This work was completed to a PFS level of detail or greater (for more detail see 2020 PFS update). • Those parts of the Mineral Resource that were within proposed mine design were used as the basis for determining the Ore Reserve. As such the Ore Reserve estimate is a subset of the total Mineral Resource and not an addition to the total Mineral Resource. • Indicated Resources are converted to Probable Ore Reserves by applying appropriate mining factors • Measured Resources are converted as Proven Ore Reserves by applying appropriate mining factors |

| Mining factors or assumptions |
Bonnie Vale Resource • The Bonnie Vale Underground mine predominantly applies an open stoping with backfill (RW or CRF). Regular rib pillar panel stopes and sill pillar panel stopes are designed to provide for the local support and the mine's stability during the normal mining operations. The proximity voids of these pillar stopes are backfilled with Cemented Rock Fill (CRF) that assist the final extraction of these pillar stope panels. • The general bottom-up mining sequence is planned to extract all resource ore lodes. The stope void is to be filled using a combination of the Cemented Rock Fill (CRF) and Loose Waste Fill (LWF) to allow the full extraction of the designed pillar resources. • Detailed stope designs are used where the grade control drilling are complete; otherwise, preliminary stope designs are used. • Grade control assumptions are in line with practice developed. Development will be routinely mapped and sampled, stope production will be regularly sampled, and monthly mine production will be reconciled to the milled tonnes and grade. • A minimum mining width of underground development is 3.0m, and for underground stoping a minimum width of 2.0 m. • Mining dilution and recovery factors used in the ore reserve estimate are detailed as per below: Reserve Mining Block type Models used Dilution % Dilution Grade g/t Mining recovery % Stope Panels (to be CRF-backfilled) Resource model built-in Stope section+10% External 0 90 Stope Panels (to be RW- backfilled) Resource model built-in Stope section+10% External 0 90 Stope Panels ( Designed Operational Rib or Sill Pillars - Surrounded by CRF-backfill).
