Pyramid Gold Project
Minotaur Exploration (ASX: MEP) completed its due diligence and will proceed to acquire 100% ownership of the Pyramid Gold Project from Avira Resources Ltd (ASX: AVW). The Pyramid tenement group is located 180km south of Townsville (Figure 1). The project, covering 150km[2] embraces two main areas prospective for gold, being the West Pyramid Range and East Pyramid Range (Figure 2).
Minotaur is attracted to the project by the very credible drilling history and an extensive geochemical database, positioning Pyramid as a compilation of advanced gold exploration prospects. West Pyramid Range offers significant potential to expand the gold mineralisation footprint defined through historic work, especially along an 8km section of the Gettysberg Fault corridor. The East Pyramid Range is less advanced, however Minotaur is of the view the area offers potential for Intrusion Related Gold Systems (IRGS), similar in style to other well-known gold deposits in the district (Figure 1) such as Mount Leyshon (+3.5Moz) and Mount Wright (+1Moz).

Minotaur’s Review of Historic Exploration
West Pyramid Range
Most of the drilling at the Pyramid project was focused along the West Pyramid Range, adjacent the northeast trending Gettysberg Fault (Figure 2), targeting surface gold geochemical anomalies at Sellheim, Gettysberg, Marrakesh and Pradesh with bedrock gold mineralisation discovered at each location. Mineralisation is hosted in sedimentary rocks (sandstone, siltstone, phyllite) with strong sericite-silica+/-chlorite alteration, variable quartz veining, and finegrained sulphide (mostly pyrite) and is best described as fault-related, lode-style gold mineralisation.
Gettysberg Prospect
Gettysberg is the most advanced prospect within the Pyramid project and remains highly prospective for additional gold mineralisation. Drilling covered around 600m of strike defining an NNE gold envelope around 500m long, ranging 25m-100m wide (Figure 3) to a vertical depth of 165m. The gold envelope plunges shallowly NNE.
A thorough review of historic exploration drilling data has been undertaken and a summary of all significant gold drill intercepts is presented in Table 1 and Figure 3. Selected, stand-out historic gold assays include:
-
35m @ 4g/t Au (MGTRC016)
-
15m @ 4.22g/t Au (MGTRC018)
-
8m @ 7.31g/t Au (MDRC031)
-
12m @ 4.8g/t Au (MDRC034)
-
35m @ 2.22g/t Au (MDD002)
-
20m @ 2.18g/t Au (MGTRC009)
-
■
-
23m @ 3.22g/t Au (MDRC033) 16m @ 2.6g/t Au (MGTRC020)
Mineralisation is primarily hosted in sandstone that is sericite altered and variably quartz-veined with attendant silica alteration. Gold mineralisation appears to be later and associated with dark chlorite and fine-grained sulphide (pyrite +/- arsenopyrite) in fracture veinlets and breccia where more advanced.
Minotaur’s new geological model for mineralisation indicates there are discrete higher-grade gold zones within the broader gold envelope, termed ‘shoots’. These shoots appear to coalesce toward the SSW where very high-grade gold mineralisation occurs in a zone of breccia adjacent an interpreted fault (Figure 4). The main zone of mineralisation stops abruptly at the SSW end against a set of interpreted north-south faults, west of which only sporadic gold mineralisation was intersected in drilling. Similarly, the higher-grade shoots appear to stop toward the NNE and may end against another north-south fault. In both instances, on-strike extensions to mineralisation may exist offset by later movement of those faults but not tested by existing drill coverage. Additionally, in the central part of the prospect where multiple shoots are defined down dip and potential exists there for extensions to mineralisation.
IP geophysical surveys are typically undertaken to map out the presence of sulphide; sulphide occurs with gold mineralisation at Gettysberg. Raw data files were sourced from an Induced Polarisation (IP) geophysical survey conducted over Gettysberg in 2007. Five (5) lines of IP data over Gettysberg, each spaced 200m apart, covered 800m of strike. These data were deemed to be of poor quality at the time and not used to guide subsequent drilling.

Minotaur reprocessed the data and determined it to be of suitable quality for modelling. Minotaur’s models show chargeability zones on all 5 lines producing an anomaly at least 800m long, open at each end. The chargeability anomaly shows a very clear spatial association with gold mineralisation and is poorly drill tested at both ends (Figure 5).

Marrakesh Prospect
Drilling at Marrakesh initially targeted strong gold-in-soil anomalies associated with sub-cropping silica-sericite altered and brecciated phyllite. Six (6) RC holes on 3 drill fences along 500m of strike of an interpreted NE-trending structure were completed in 1992 with all holes intersecting gold mineralisation; the best intercept returning 45m @ 0.78g/t Au, including 7m @ 1.26g/t Au in hole MDRC003 (Figure 6, Tables 1 and 2). Depth of drill penetration for these holes is relatively shallow at 45-110m. Three (3) additional RC holes were drilled in 2015 parallel to the NE gold trend targeting cross structures but failed to return gold values of any significance.
Mineralisation is associated with strongly silica-sericite altered phyllite with quartz veins and sulphide (pyritearsenopyrite and minor sphalerite), having strong similarities to Gettysberg. The system is open along strike in both directions and worthy of additional drilling. However, given there is sulphide associated with gold, it seems a detailed investigation of the prospect via an IP geophysical survey over and along strike of known mineralisation would be highly beneficial to guide future drilling.

Sellheim Prospect
Drilling at Sellheim comprised 28 RC holes covering an area around 500m long and 200m wide along a NE structural corridor. Mineralisation appears patchy and drilling did not intersect any zones of high grade gold, yet substantial widths of low grade mineralisation were encountered in some holes, such as two scissor holes that each intersected +100m of mineralisation, including 155m @ 0.22g/t Au from surface to end-of-hole in MGTRC014 and 124m @ 0.26g/t Au from 25m in MGTRC015 (Tables 1 and 2). Mineralisation is hosted in sericite-silica altered sandstone with variable quartz veining and fine-grained sulphide and shows similarities to Gettysberg. No diamond core was drilled at Sellheim which hinders a detailed geological interpretation and no IP geophysics was conducted to help map out the system and show if past drilling covered the most prospective area. Minotaur will continue to review data for Sellheim to determine if further work is warranted.
Pradesh Prospect
Drilling at Pradesh initially targeted a 300m long strong NE-trending gold-in-soil anomaly associated with subcropping quartz-veined phyllite. Four (4) RC holes were drilled in 1992 on a single line across this trend with 1 hole (MDRC007) intersecting 84m @ 0.21g/t Au from surface (Tables 1 and 2). Two (2) additional RC holes were drilled in 2015 parallel to the NE gold trend and toward each other targeting cross structures. Hole MGTRC026 intersected 3 zones of low-grade gold mineralisation, possibly within the NE gold zone, with a best intercept of 37m @ 0.27 g/t Au from surface. MGTRC027 incepted patchy mineralisation throughout with a best intersection of 34m @ 0.25g/t Au from surface (Tables 1 and 2). Mineralisation is associated with strongly silica-sericite-chlorite altered phyllite with quartz veins and sulphide (pyrite-arsenopyrite and minor sphalerite), having strong similarities to Marrakesh. An IP geophysical survey over and along strike of known mineralisation would inform a follow-up drill decision.
Djoser (Dempsey’s East) Prospect
Djoser lies along the West Pyramid Range but inboard of the Gettysberg Fault where gold mineralisation is known to occur at Gettysberg, Marrakesh, Sellheim and Pradesh (Figure 2). Soil geochemical data defines an area 600m x 500m of +50ppb Au-in-soil at Djoser, exhibiting a coincident strongly elevated Zn, Pb, Cu and As halo, differing from the above mentioned gold prospects that typically display elevated Au-As soil anomalies. Djoser appears to be more like the surface geochemical anomalies along the East Pyramid Range and may have affinities with Intrusion Related Gold Systems (see details below for East Pyramid Range). Djoser has not been investigated with drilling or electrical geophysics and Minotaur did not inspect the prospect area during a recent due diligence site visit, however it presents as an intriguing target and will be considered in time.
Gettysberg Fault Corridor
Minotaur believes that systematic IP geophysical surveying will be highly beneficial to help with drill targeting along the Gettysberg Fault corridor. Previous drilling focused immediately beneath surface gold geochemical anomalies meaning any deeper, offset or blind mineralisation may not have been tested. Gold mineralisation at Gettysberg, Marrakesh, Sellheim and Pradesh is known to contain sulphide and, at Gettysberg, there is an IP chargeability anomaly spatially associated with mineralisation.

Minotaur views the 8km-long Gettysberg Fault corridor between Sellheim and Pradesh (Figure 2) to be highly prospective. The corridor deserves to be investigated more thoroughly for blind mineralisation at each of the known gold occurrences and elsewhere along the fault where the surface gold geochemical signature is more subdued and was not the focus of previous exploration.
East Pyramid Range
Nine (9) holes were drilled within the broader East Pyramid Range area more than 20 years ago, prior to any systematic soil sampling. Geochemical sampling over an area 4km x 2km outlined numerous areas of strong surface gold anomalism (Figure 2), that also exhibit coincident strongly elevated Zn, Pb, Cu and As. Later soil sampling by Avira also located areas of surface gold anomalism but those were not fully drill tested.
Parts of the East Pyramid Range were inspected during a recent due diligence site visit. Field observations support the earlier view that this area remains highly prospective for an IRGS. The area is relatively rugged and will require careful planning for future exploration activities. However, it appears the best way to advance this area and develop a suite of drill targets is to conduct an IP survey to investigate if zones of sulphide are developed that may be linked to gold mineralisation at depth.
Activity Outlook
Minotaur readied to conduct drilling at Gettysberg on 1 December 2020 to test for continuity of and extensions to the interpreted higher-grade gold shoots within the main envelope of mineralisation. This week’s COVID outbreak in Adelaide and consequent closure of the Queensland border to travellers from South Australia stymies that plan, putting field mobilisation in abeyance until access restrictions are relieved.
Results of first drilling at Gettysberg, now likely not until early 2021, should lead to an expanded exploration program, such as follow-up drilling of the higher-grade gold zones, drill testing the IP chargeability anomaly and extension of the IP geophysical coverage to determine if the sulphide systems extend further along strike as possible hosts of gold mineralisation.
Elsewhere across the project area, Minotaur believes that a staged systematic IP geophysical survey along the Gettysberg Fault corridor will be highly beneficial. It is expected this would initially be aimed at searching for extensions to mineralisation at each of the known gold occurrences, especially at Marrakesh and elsewhere along the fault corridor where the surface gold geochemical signature is more subdued. Activities at Djoser prospect and along the East Pyramid Range are yet to be determined but the overall aim would be to advance these to drill status.

APPENDIX A
JORC Code, 2012 Edition, Table 1
Section 1: Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. |
Gold mineralisation at Gettysberg, Marrakesh, Sellheim and Pradesh prospects within the Pyramid project have been sampled by drilling from surface to a maximum vertical depth of 165m. Reverse circulation (RC) drilling is the dominant method employed during multiple historic programs conducted between 1987 and 2018. Limited diamond cored drilling (3 holes) occurred in 1992. RC drilling returns a sample of broken rock chips collected at site at the time of drilling, typically sub-sampled at the drill site for laboratory analysis. Drill core from diamond drilling technique is removed from the drillsite and later split by a core saw and portioned for laboratory analysis. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
Documentation of measures taken by previous operators (Battle Mountain Australia, Dalrymple Resources, Chalcophile Resources, MGT Mining/ Avira Resources) during drilling programs 1987-2018 to ensure sample representivity is incomplete, however it is assumed that industry standard best practice has been applied. Within the available historic documentation, past operators have recorded drill sample recovery monitoring, observation of negligible cross-contamination of sample and mentioned inclusion of QC sample material in laboratory submissions e.g. reporting for the 2015 MGT Mining drill program managed by contractors Terrasearch describes a rigorous QAQC program including submission of 108 sample duplicate pairs, which showed sample representivity to be within expectation. |
|
| Aspects of the determination of mineralisation that are Material to the Public Report. |
Historic drillhole assays, in conjunction with historic geological logging data, have been used by MEP to gain a 3- dimensional understanding of the mineralisation at Gettysberg. The number of drill holes at each of Sellheim, Marrakesh and Pradesh prospects, referred to in the body of this report,are not sufficient toproduce detailedgeology |

| interpretations. However, the data provide sufficient evidence to indicate that each of those systems contain gold mineralisation and some of the prospects, for example Marrakesh, look to show good prospectivity to enhance the area of gold mineralisation including potential for areas of higher grades. |
||
| In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1m samples from which 3kg was pulverised to produce a 30g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
Historically, industry standard sampling methodologies have been applied to exploration at Gettysberg, Marrakesh, Sellheim and Pradesh prospects. Gettysberg: 1992 (Dalrymple Resources): 1m HQ (63.5mm) core samples typically with some 4m core composites for hole MDD003. 1m RC samples from 4½” diameter hammer bit passed through cyclone at rig, bagged in plastic, passed through 7/8:1/8 splitter, 7/8 retained as bulk sample, 1/8 composited over 4m then mixed through splitter then 2kg sample for assay obtained by spear method. If dictated by geology, bulk 1m samples run through splitter to produce 2kg split as a check sample. Lab analysis for Au by 50g fire assay by Analabs Townsville with AAS finish, multielement analysis by perchloric acid digestion with ICP finish. High grade 4m composites reassayed from same pulp by 50g fire assay and separate check samples from a different spear analysed for Au by 50g fire assay. Some additional samples submitted for 50g fire assay samples with gravimetric finish. Some 1m samples also check assayed with 30g fire assay with ICP finish. Lab check conducted providing new composites split off bulk 1m samples in field to ALS Townville for assay by 50g fire assay and bulk cyanide leach (BCL) methods. The two labs and methods agree. The comparison of 4m composites and individual 1m samples is very close, confirming the 4m compositing as a valid representative methodology. Some irregular composite intervals of 2m accommodate variable end-of-hole depths. 1993 (Dalrymple Resources): 1m RC samples from 5½” diameter face samplinghammerpassed |

Lab analysis for Au for perchloric acid digestion, 50g fire assay with AAS finish by Analabs Townsville. Some irregular composite intervals of 2m or 6m accommodate variable end-of-hole depths. 2006 (Chalcophile Resources): 1m RC samples from 4½” diameter hammer bit, bagged in plastic, no cross-contamination, 2m composites created from splits of 1m samples after confirming the pair of 1m bulk samples to be the same size. Reference material of known Au grade inserted in the sample sequence at the end of every hole. 2m composite samples analysed by ALS Chemex Townsville for Au by 50g fire assay, multielement analysis by aqua regia digest with ICP finish. 1-2kg reference sample taken from each 1m bulk sample and stored, remainder of bulk sample disposed of after program end and receipt of all assays. Some 1m samples included in dataset. 2012 (MGT Mining): 1m RC samples from 4” diameter hole composited to 2m sub-samples for analysis by ALS by 50g Au analysis by fire assay and multielement analysis by aqua regia digest and ICP-AES finish. Duplicate, blank and commercial reference materials inserted in the sampling sequence with QAQC results lending high confidence to the sampling methodology. Reference sample taken from each 1m bulk sample and stored, remainder of bulk sample disposed of after program end and receipt of all assays. Some 1m samples included in dataset. 2015 (MGT Mining): 1m RC samples collected via 134mm diameter face sampling hammer, passed through cyclone and a 7/8:1/8 splitter at rig, 7/8 retained as bulk sample, 1/8 caught in a calico bag for assay. Lab analysis for Au by 50g fire assay by ALS with AAS finish. At the laboratory any >1g/t Au samples were re-sampled and re-assayed, any Au valuesgreater than the upper calibration range |

| of AAS were diluted and redetermined. Duplicate, blank, commercial reference materials and internal reference materials inserted in the sampling sequence with QAQC results provided high confidence in the sampling methodology. Significant intercepts were re-assayed from 1/8 splits taken from the original bags as part of the QAQC process, increasing confidence in the data. Sample recovery and contamination were logged downhole metre by metre. 2018 (Avira Resources): 1m RC samples collected via 134mm (5½”) diameter face sampling hammer. Lab analysis of 1m samples for Au by 50g fire assay by ALS with AAS finish. Duplicate, blank, commercial reference materials and internal reference materials inserted in the sampling sequence with QAQC results provided high confidence in the sampling methodology. Sample recovery and drillhole moisture were logged downhole metre by metre. Recoveries 100% except initial 5-10m collaring and 99-127m in hole MGTRC039 (hole blockage, drilling ceased to resolve before continuing to EOH). All four holes dry therefore nil cross-contamination. Marrakesh: 1992 (Dalrymple Resources): 1m RC samples from 4½” diameter hammer bit passed through cyclone at rig, bagged in plastic, passed through 7/8:1/8 splitter, 7/8 retained as bulk sample, 1/8 composited over 4m then mixed through splitter then 2kg sample for assay obtained by spear method.

At the laboratory any >1g/t Au samples were re-sampled and re-assayed, any Au values greater than the upper calibration range of AAS were diluted and redetermined. Duplicate, blank, commercial reference materials and interval reference materials inserted in the sampling sequence with QAQC results provided high confidence to the sampling methodology. Significant intercepts were re-assayed from 1/8 splits taken from the original bags as part of the QAQC process, increasing confidence in the data. Sample recovery and contamination were logged downhole metre by metre. |

| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. |
Sample recoveries during drilling by previous operators 1987-2018 were not always documented, but comment has been made in several drilling reports that recoveries were monitored and cross-contamination was negligible. During drilling by MGT Mining/Avira Resources during 2015/2018 sample recovery and drillhole moisture were logged downhole metre by metre recording typically good recoveries from dry drillholes with moisture and poor recoveries noted in detail when encountered. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
Measures taken by previous operators 1987-2018 to maximize sample recovery and representivity are assumed to have been industry best practice. |

|---|---|---|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Any bias or relationship between sample loss and gold grade realized by previous operators 1987-2018 has not been documented. Available documentation noted drill recoveries to be acceptable. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. |
Historic geological drill logging data have been reviewed by MEP using historic statutory reports and company databases supplied by project vendor Avira Resources. Available historic geological data are sufficiently detailed to support geological interpretation and infill drill targeting. A key selection of historic drill core and RC chip trays from Gettysberg, Marrakesh, Sellheim and Pradesh prospects were examined by MEP and compared to historic logging as part of the due diligence site visit. At this stage of exploration detailed geotechnical logging is not required. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. |
Geological logging is intrinsically qualitative. Limited core photos (1992 drilling) and RC chip tray photos (2018) are available from historic drill programs. |
|
| The total length and percentage of the relevant intersections logged. |
Historic drillholes were geologically logged in entirety by previous operators and these data are available to MEP. The historic data provide sufficient detail to make informed assessment of the prospect geology and historic assay results for Gettysberg, Marrakesh, Sellheim and Pradesh prospects. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
Drill core was sampled as half core at 1m intervals as is appropriate for the style of mineralisation at Gettysberg. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
Past use of riffle splitting and spearing RC sub-samples is noted in documentation for Gettysberg, Marrakesh, Sellheim and Pradesh prospects historically. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. |
Industry standard protocols have been used during historic exploration at Gettysberg, Marrakesh, Sellheim and Pradesh to check adequacy and accuracy of sampling regimes. |
|
| Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. |
Historic geological logging of RC samples and cored samples was conducted by geologists with sufficient detail to ensure representive selection of sample intervals based on geological understanding of the mineralised systems at Gettysberg, Marrakesh, Sellheim and Pradesh prospects. |

Historic documentation of QAQC methodologies is incomplete. MEP assume industry standard sampling methodologies have been applied to exploration at Gettysberg, Marrakesh, Sellheim and Pradesh prospects, e.g. reporting for 2015 MGT drill program managed by Terrasearch describes a rigorous QAQC program including submission of 108 sample duplicate pairs, which showed sample representivity to be within expectation. |
|

Resources, Chalcophile Resources and MGT Mining/Avira Resources to ensure acceptable assay data accuracy and precision. Historical QAQC procedures are referenced in a number of available documents. |
|
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
All historic drilling data including collar coordinates, hole orientation, total depth, sampling intervals and lithological logging were collated by the vendor Avira Resources and provided to MEP. Significant intersections have been verified during MEP’s due diligence process. |
| The use of twinned holes. | Some twinned or scissor holes have been drilled historically. Additionally, due to site terrain and access requirements, historic drillholes at Gettysberg, Marrakesh, Sellheim and Pradesh were necessarily drilled at a variety of orientations from either side of the mineralised corridor. Drillholes from all orientations appear to support the interpreted geology and grade of the mineralisation. |
|

All historic collar location data have been stored by Avira Resources within an Explorer 3 database according to AGD66 with AMG Zone 55 coordinates, as transformed from GDA94 AMG Zone 55 coordinates. Relative Level (RL) positions of collars were determined by differential GPS. Historically; pre-1993 drill collars were located at the time of drilling by compass/clinometer, no downhole surveying was undertaken; during 2006, new holes and all previous drill collars were surveyed with an Omnistar differential GPS with reference to the GDA 94 Zone 55 datum; downhole surveys for all 2006 drillholes were completed using a single shot Eastman camera inside stainless steel RC rods; accurate measurement of the collar dip/azimuth were completed with compass/clinometer; |

| 2012 drill collars were located by differential GPS; downhole surveying was completed with a Camtech Proshot tool; 2015 and 2018 drill collars were located using RTK differential GPS tied to previous drilling. At the end of the 2015 drill program, the hole collars were surveyed using real time kinematic (RTK) global navigation satellite system (GNSS). The RTK-GNSS system utilized two units in the field: a base unit with integrated receiver (Trimble SPS855 or similar) was placed on known points where real time corrections were broadcast via an inline radio (and repeater if necessary) to a roving Trimble SPS985 RTK-GNSS antenna equipped with a TSC3 controller. Both units connected to the GNSS to determine their position. Satellite coverage was typically 16-17 and never less than 11. The rover position was corrected in real time according to known positional errors at the base. In undulating, lightly forested, favourable GPS environments such as Gettysberg, Bombay and Pradesh, the precision is likely to have been less than 2 cm in both horizontal and vertical positioning over distances of up to 1 km. Forested environments Sellheim and Marrakesh are located within 1.5 km and assisted with radio repeaters, the precision is likely to be less than 5 cm. The exact precision depends on the satellite geometry during the survey but with good satellite coverage (>11 satellites) positional dilution of precision was minimal. The RTK measurements were recorded using the GDA 94 Australian datum and projected into the UTM coordinates of MGA Zone 55. All pre-existing holes within the drilled prospects were re-occupied and their positions re-measured using the same two base locations mentioned above. |

Data spacing for reporting of Exploration Results. |
Historically, data spacing of samples through the mineralised zones ranged 1m-4m with less common 2m composite samples. |

Not applicable. | |
| Whether sample compositing has been applied. | Not applicable. | |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. |
Site terrain and access requirements caused historic drillholes at Gettysberg, Marrakesh, Sellheim and Pradesh to necessarily be drilled at a variety of orientations but as close as practical to perpendicular to the interpreted strike orientation of the mineralised zones. Drillholes from all orientations appear to support the interpreted geology and grade of the mineralisation. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Some holes may not have been drilled at the optimal orientation at Gettysberg in the early stages of exploration based on earlier geological interpretations. Minotaur has revised the geological model and plans to test the model with drilling; these holes are planned to be drilled across the strike of the interpreted mineralized zones that will provide important information for future work and to validate the geological model. That information will be reported once the drilling is completed. |

|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The Gettysberg, Marrakesh, Sellheim and Pradesh prospects all lie within EPM 12887, part of the Pyramid Project group of tenements (EPM’s 12887, 19554 and 25154), the subject of a binding terms sheet and will be part of a Sale and Purchase agreement between Minotaur and MGT Mining/Avira. EPM 12887 has an existing Native Title agreement with the Bulganunna Aboriginal Corporation (CN7761) (Jangga People). There are no material issues with regard to access. |
| The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. The tenement is secure at the time of the report being submitted with no known impediments to obtaining a licence to operate. |
|
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. Substantial surface geochemical sampling and mapping has been conducted over numerous phases of exploration from 1992 – 2018. Gold was discovered by following up stream sediment sampling with most focus being at Gettysberg where field reconnaissance mapping found visible gold in weathered outcrop. Significant exploration drilling has been conducted previously over the project area with the focus being on EPM 12887. Drilling has been conducted by BMA, Dalrymple Resources, Newcrest, Chalcophile Resources and/or MGT Mining (Avira Resources) at numerous localities including Gettysberg, Marrakesh, Sellheim, Pradesh, Breccia Knoll and Sugarloaf prospects. Most of the drilling is by RC method with only 3 diamond core drill holes. An IP/resistivity geophysical survey was also conducted at the Gettysberg prospect. Data collected by previous operators have been reviewed in detail by MEP and used to support geological interpretations reported here. The historic data will be used to guide future exploration by MEP. |

| Criteria | JORC Code explanation Commentary |
|---|---|
| Geology | Deposit type, geological setting and style of mineralisation. The Gettysberg, Marrakesh, Sellheim and Pradesh mineralisation is regarded as fault-related lode-style gold mineralisation. The mineralisation is hosted in sedimentary rocks (sandstone, siltstone, phyllite) and is associated with strong sericite-silica±chlorite alteration, variable quartz veining and fine-grained sulphide (mostly pyrite). The prospective area occurs where Anakie Inlier basement rocks are upthrown against sedimentary rocks of the Drummond Basin. The project area also offers potential for Intrusion Related Gold Systems (IRGS), similar in style to other well-known gold deposits in the district such as Mount Leyshon and Mount Wright. |
| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. Summary of collar eastings and northings, hole orientation, end-of-hole depths and significant intercept depths are tabulated in the body of this document (Table 1 and 2). |
| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. No data deemed material to the understanding of the historic exploration results and proposed geological model for the Gettysberg, Marrakesh, Sellheim and Pradesh mineralisation have been excluded from this document. |
|
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. The weighted average assay values of the mineralised intervals from historic drillholes referred to in the body of this document were calculated by multiplying the assay of each drill sample by the length of each sample, adding those products and dividing the product sum by the entire downhole length of the mineralised interval. No minimum or maximum cut-off has been applied to |

|---|---|
| any of the historic drillhole assay data presented in this document. Some sample intervals have an average gold grade where those samples were analysed more than once and by other gold methods. |
|
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. Some sample intervals have been reported where discrete zones of higher-grade gold are present within a wider zone of lower grade. These intervals of higher- grade gold are presented in this report to support the concept that zones of structural complexity that appear to have focused gold mineralisation into certain areas and that at Gettysberg for example, these zones appear to be relatively continuous. Reference should be made to Figures 3-5 and Table 1 in the body of this report. |
|
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalents have been reported in this document. |
|
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. Due to site terrain and access requirements, historic drillholes at Gettysberg, Marrakesh, Sellheim and Pradesh were necessarily drilled at a variety of orientations from either side of the mineralised corridor. Historic drillholes have not always been drilled perpendicular to the mineralisation zones as reinterpreted by MEP; however drillholes from all orientations appear to support the interpreted geology and grade of the mineralisation. |
| If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. Drill core data and surface mapping suggest that the mineralized envelope at Gettysberg likely strikes NNE and plunges shallowly NNE. In detail, the internal geometry of the mineralized envelope appears to have discrete zones (shoots) of higher-grade gold mineralisation. These shoots strike in the same direction as the envelope but are interpreted to dip steeply SE (Figures 3-5). Minotaur plans to test this model with drilling; holes are planned to be drilled across the strike of the interpreted mineralized zones that will provide important information for future work and validate the geological model. That information will be reported once the drilling is completed. |
