Drilling of MMI gold anomalies
A Mobile Metal Ion (MMI) geochemistry survey was completed in the discovery area in 2021 highlighting many separate drilling targets.
A total of seventeen (17) RC holes for 1,271m were drilled to test several of the MMI gold anomalies as shown in Figure 3, below. Initial drilling results have successfully intersected shallow and wide down hole zones of gold mineralisation.
Drillhole YBRC033 has returned a shallow wide intercept of 15m @ 0.38g/t gold from 15m beneath an MMI anomaly (Figure 4) on drilling cross section 6751740. This gold mineralised zone is interpreted to continue approximately 320m to the north-west along a prominent shear where RC holes YBRC018 ( 4m @ 0.38g/t Au from 23m) immediately beneath the barren transported overburden, and YBRC 024 ( 17m @ 0.43g/t from 47m) respectively. The area is masked by approximately 20m of barren transported overburden, refer to Figure 5 below.
The gold in drilling intersections confirm that the MMI method is working in this area with barren transported overburden. Further MMI gold anomalies will be drill tested with the resumption of drilling activities at Yidby in 2022.
High resolution ground magnetic survey aids in developing gold model
The Yidby gold mineralisation is a blind discovery; the area is covered by up to 20 metres of barren transported overburden that overlies and masks the gold mineralisation.
During December 2021 Surefire completed a high-resolution ground magnetic survey over the discovery area. The survey, undertaken at a line spacing of 10m with a continuous recording magnetometer, was designed to assist in the interpretation of the gold intercepts obtained from recent and past RC drilling.
The interpretation of the ground magnetic data by consulting geophysicists, concluded that:
-
the gold is hosted in ultramafics and closely associated with the axial plane of a prominent north-west striking and plunging antiform suggesting that saddle reef style gold also exists on this prospect;
-
major north-west and east-west trending shear zones dissect the host rocks; and
-
secondary north-south and north-north-west trending faults may have acted to remobilise gold to form high grade gold accumulations.

The gold mineralisation drilled to date lies on the south-western flank of the interpreted antiform. The north-eastern flank of the antiform remains largely undrilled.
An important element of this model is saddle reef gold. Saddle reefs have the potential to host many simultaneous styles of gold mineralisation within the one larger gold mineralised system. Examples from other deposits are (Figure 6 ):
-
Within the axial plane axis as stockwork veins
-
Concordant to bedding
-
Discordant to bedding within shears and faults, and
-
Breccia zones
The exploration work completed to date is focussed on the 1.6km long MMI gold anomalies on the western flank of the antiform. The eastern flank of the antiform is yet to be tested by drilling.

Surefire has now updated the mineralisation model for the Yidby Road Gold Project and is using it to define targets for the next drilling campaign. Importantly, the new interpretation implies the gold mineralisation drilled to date is just one part of a much larger gold, possibly multiphased, gold system.
“ The recent drilling results support our previous drilling results and the interpretation of wide gold zones at the Yidby Road Gold Project. The Surefire mineralisation model points to the likelihood a high tonnage gold deposit at Yidby. Your company is working diligently towards that goal”, Mr Nikolaenko said.
Drilling Planned to:
-
Drill test the open extensions of the Yidby Road Gold Deposit to both the north and south-east;
-
Drill test additional MMI anomalous exploration zones beneath the barren overburden; and
-
test the Money Anomaly targets generated by the ground magnetic survey and MMI geochemistry.

JORC Code, 2012 Edition:
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 (e.g., cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g., ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g., submarine nodules) may warrant disclosure of detailed information. |
Reverse Circulation drilling was used to obtain 1m samples weighing approximately 3kg from the splitter on the cyclone and submitted to the laboratory (Nagrom laboratories). The entire sample was crushed to - 2mm then either riffle-split then pulverised to 95% passing 75 microns to produce a 50g charge for Fire Assay gold (Au) analysis. Selected samples in zones of lower prospectivity were composited to 4m after the crushing stage at the lab before 50g charge Fire Assay analysis. Where grades of >0.1 g/t Au are returned for the composite the individual 1m samples are assayed for that zone. |
| Drilling techniques | Drill type (e.g., core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g., core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
Reverse Circulation drilling was completed using a face sampling hammer. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. 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. |
RC drilling was bagged on 1m intervals and an estimate of sample recovery has been made on the size of each sample. The cyclone is shut off when collecting the sample and released to the sample bags at the completion of each metre to ensure no cross contamination. If necessary, the cyclone is flushed out if sticky clays are encountered. |

|---|---|---|
| Samples were weighed at the laboratory to allow comparative analysis. |
||
| 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. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The total length and percentage of the relevant intersections logged. |
Geological logging was conducted per 1m sample with lithologies and weathering zones being documented throughout. Representative samples from the “green bags” are sieved and in fresh rock, washed, and placed in chip trays for each hole. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. For all sample types, the nature, quality and appropriateness of the sample preparation technique. Quality control procedures adopted for all sub-sampling stages to maximise samples representivity Measures taken to ensure that the sampling is representative of the in- situ material collected, including for instance results for field duplicate/second-half sampling. Whether sample sizes are appropriate to the grain size of the material being sampled. |
Not applicable to this announcement Every 1m RC interval was sampled as a dry primary sample in a calico bag off the cyclone/splitter. Drill sample preparation and analysis carried out at registered laboratory (Nagrom Laboratories). Sample preparation is dry pulverisation to 95% passing 75 microns. Field sample procedures involve the insertion of registered Standards and duplicates generally every 25m and offset. Sampling is carried out using standard protocols as per industry practice. Sample sizes range typically from 2 to 3kg and are deemed appropriate to provide an accurate indication of gold mineralisation. |
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g., standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e., lack of bias) and precision have been established. |
Gold assays at Nagrom Laboratories in Perth, WA, using a 50g charge for Fire Assay gold (Au) total analysis. Selected samples in zones of lower prospectivity were composited to 4m after the crushing stage at the lab before 50g charge Fire Assay analysis. Where grades of >0.1 g/t Au are returned for the composite the individual 1m samples are assayed for that zone. Field sample procedures involve the insertion of registered Standards and duplicates generally every 25m and offset. Standards and duplicate assays are also completed at the Lab. |
| Verification of sampling and assaying | The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, |
Selected intersections have been calculated at various cut-off grades, including a 0.1g/t minimum cut-off for the “mineralised envelope” and including “economic” cut-off grades |

applicable to the significant intersections (e.g. 0.3 g/t Au, 1.0 g/t Au). Where internal waste is included, the included zone must average above the stated cut-off grade to be across the added interval. Geological and sample data was entered into spreadsheets on site and stored on the Company’s database. |
|
| Location of data points | Accuracy and quality of surveys used to locate drill holes (collar and down- hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
Siting of planned drillholes was completed using a DGPS and adjusted with hand-held GPS where necessary. Final collar locations will be surveyed using DGPS, which will also provide topographic data. Grid system MGA 2020, Zone 50. Downhole surveys have been completed while drilling on recent deeper holes using a REFLEX Gyro Tool. Open hole surveys will be completed on all previous and current holes not yet surveyed, subject to blockages downhole. |
| Data spacing and distribution | Data spacing for reporting of Exploration Results. Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. |
Sample data down hole is at no more than 1m intervals (with selected intervals composited at the lab). Data spacing in terms of pierce points varies from 25m to 100m from previous intersections. Assessment as to whether sufficient data has been generated to establish the degree of geological and grade continuity appropriate for (JORC 2012) Mineral Resource estimation procedure(s) is underway and, if necessary, additional drilling will be carried out to establish continuity. |
| 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. 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. |
Drilling orientation is designed to test the mineralisation at as close as possible to orthogonal to the mineralisation, therefore not biasing the sampling or intersection lengths. All intersections are downhole widths with the true widths not determined at this early stage of exploration. |
| Sample security | The measures taken to ensure sample security. |
Samples transported by Company personnel direct to the Laboratory as soon aspossible after drilling. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
A full review of QAQC data will be completed once all results received. |

Section 2: Reporting of Exploration Results
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
Located 320km northeast of Perth in the mid-west region of Western Australia. E 52/2390 and E52 /2426 are granted tenements with a 100% interest acquired by Surefire Resources NL under a sale agreement from the tenement holder Beau Resources Pty Ltd. A 2% Royalty on Gold production is payable to Beau Resources Pty Ltd. |
| Exploration done by other parties | Acknowledgment and appraisal of exploration by other parties. |
Previous exploration work has been completed by Normandy and Monarch Gold. Normandy work included aircore drilling and limited RC drilling, including at the Yidby Road Prospect. Drilling intersections in easterly oriented drilling were followed up by Surefire using westerly oriented holes and the Normandy drilling was shown to be drilled in the wrong orientation for the easterly dipping mineralised structures. |
| Geology | Deposit type, geological setting and style of mineralisation. |
Gold mineralisation at the project is orogenic, hosted within quartz veining with minor sulphides in ultramafic/mafic lithologies and felsicporphyryintrusions. |
| 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.

| Data aggregation methods | In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g., cutting of high grades) and cut-off grades are Material and should be stated Where aggregate intercepts incorporate short lengths of high- grade results and longer lengths of low-grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
Selected intersections have been calculated at various cut-off grades as shown in Table 1, including a 0.1g/t minimum cut-off for the “mineralised envelope” and including “economic” cut-off grades applicable to the significant intersections (e.g. 0.3 g/t Au, 1.0 g/t Au). Where internal waste is included, the included zone must average above the stated cut-off grade to be across the added interval. No cutting of high-grades has been carried out. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the min- eralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g., ‘down hole length, true _width not known’). _ |
Orientation of mineralised zones are still to be determined in detail. All intercepts reported are downhole depths. |
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Drillhole locations and interpreted mineralisation outline are shown in Figures in the body of the release. Appropriate cross sections are shown in the body of the release. Tabulations of hole statistics are shown in the body of the release. |
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Results. |
Tabulations of hole statistics are shown in the body of the release.. |
| Other substantive exploration data | Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk |
