Ora Banda Mining Limited (ASX: OBM) (“Ora Banda”, “Company”) is pleased to provide an update on the Riverina Underground Mine and Sand King Development Project - which together form the centrepiece of the Company’s DRIVE to 100 Project, which is targeting production of more than 100,000 ounces in FY25.
2
Ora Banda Mining Limited’s Managing Director, Luke Creagh, said:
“The Riverina Underground mine will soon fulfil the role of the primary producing asset at Davyhurst, taking over from the Siberia open pits. The mine is now well advanced with stoping coming online and impressive grades coming back from the infill drilling and face sampling. We are pleased with the rate of progress and look forward to ramping this up to commercial production expected in the June quarter and seeing the full potential benefit of the stoping tonnes and grade reaching the processing plant.
“The recent Sand King drilling success continues with a focus on the newly discovered high grade lode system in the north, hidden from surface under the gently dipping ultramafic unit. We are currently advancing the mining study to determine the potential for Sand King to become the second underground gold mine for the Davyhurst Project.”

Riverina Underground Mine
Stoping commenced in March with rapid ramp up set for June Quarter
Progress in the mine continues to advance strongly, with stoping commenced on the first level, ore development well underway on the second level (2275) and with the decline advancing toward the third level (2255). As the capital development advances ahead of the working areas the optionality continues to increase as more development headings become available to the jumbos.
Geologically the lode widths and grades intersected in the ore development drives continues to typically meet and/or exceed the pre-mining expectation. The lode geometry is regular and predictable, combining with ground conditions that are considered good.
The overall development rates remain strong, with March achieving 588 metres, which is the highest monthly advance rate for the Project to date. Management focus is aimed at a continued increase in the development metres towards the steady state target of 650m per month.

Sand King Development Drilling Program Riverina
OBM commits to Phase 3 program based on drilling success
Recent drilling has led to a newly discovered high grade lode system in the north of the Sand King project area that combines well with the previously discovered discrete high grade lodes in the south of Sand King. Further success has led the Company to expand the Phase 2 program that aims to expand the known resource and to further build the Sand King mineral resource base.
Work has commenced on a mineral resource update that will underpin the Sand King mining study. Infrastructure, hydrological, geotechnical, mining and metallurgical evaluations are well advanced.

BACKGROUND INFORMATION
Siberia Project Overview
The Siberia project comprises the Missouri, Sand King, Palmerston, Bewick Moering, Theil Well and Black Rabbit deposits with a total gold endowment of 750koz[1] , made up of published mineral resources of 4,149,000 tonnes @ 3.4g/t for 458,000 ounces[2] and historical production of 293,000 ounces at a grade of 2.5g/t[1] , predominantly from open pit sources. Siberia is located 37km southeast of the Davyhurst processing plant and approximately 80km northwest of Kalgoorlie within the Eastern Goldfields of Western Australia.
Siberia has been the focus for the Company’s most recent open pit mining endeavours having produced 118,000 ounces[1] since mining recommenced in 2021. The Company is now turning its attention to the underground potential of the Siberia Complex noting that 95% of the 12,700 holes drilled to date are less than 100 metres in depth, meaning the underground exploration search windows are largely unexplored.
Sand King Overview
Sand King was previously mined by Western Mining Corporation (WMC) from the late 1980’s to 1991 by open pit methods, producing approximately 50,000 ounces at 4.8g/t. Under OBM, a small cutback to the south commenced in August 2023 and was completed in early January 2024, mining 11,400 ounces at 1.7g/t. The Sand King mineralised system is over 1km of strike length, with mineralisation tested to over 300 metres at depth and remains open both along strike and at depth.
Geology and Structural Synthesis
Early Shears
There are early shears in two distinct orientations at Sand King. One shear system strikes towards 010° and the other strikes towards 330°. Both dip to the north-east, forming a conjugate pair. Several definable shear structures have been either mapped in the pit and/ or logged in the diamond core. The shears are ductile, having formed in a deep tectonic environment. The shears vary from a few cm to +/-1 metre wide and were poorly mineralised or unmineralised at formation.
Mineralised vein system
Tension veins consisting of quartz, potassic alteration with sulphides and gold were later emplaced at Sand King. The tension veins formed from hydrostatic pressure at shallower depths and have either a 060° or 090° strike orientation. The 060° orientation is dominant with strike lengths of up to several hundred metres while the 090° veins are less strike extensive and frequently terminate on the 060° veins.
The interaction of late veins with early shears
The behaviour of the tension veins when they intersect the early shears depends on the shear and vein orientations. Observed interactions include:
- 090° veins frequently terminate on 060° veins
1 Historical production figures sourced from internal Company Records (updated from Monarch Gold 2008)
2 For further details see ASX Announcement dated 26 October 2023
12
-
060° and 090° veins terminate and at times migrate along 330° shears
-
Tension veins frequently pass through 010° shears
The 330° shears are strongly foliated and frequently quartz filled which becomes a host for the gold introduced by the later tension veins. When the tension veins intersect the 330° shears the ore bearing fluids migrate up and down the shear, causing grade and volume “blowouts”. The 010° shears exhibit a weak planar foliation, without quartz and are generally a poorer gold host.
Mineral stretching lineations in the 330° shears imply a steep northerly plunge to the gold mineralisation. Boudinaged quartz in shears are infrequently observed but boudin necks plunge steeply north confirming the overall mineralisation plunge. Furthermore, the intersection of the steep north dipping tension veins with the moderate north dipping 330° and 010[o] shears give a steep north plunge to the high-grade blow-outs.
Implications for mining
There are four gold bearing structural orientations at Sand King, 090°, 060°,010° and 330°. The 090° and 060° tension veins are well mineralised with good mining potential. The 330° and 010° shears are well mineralised where intersected by the 090° and 060° tension veins. Where several spaced tension veins intersect the shears, they are well mineralised over a reasonable strike length, again with good mining potential.

Appendix 2 - JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE
Section 1 Sampling Techniques and Data - Riverina
Information for historical (Pre Ora Banda Mining Limited from 1996 and 2001) drilling and sampling has been extensively viewed and validated where possible. Information pertaining to historical QAQC procedures and data is incomplete but of a sufficient quality and detail to allow drilling and assay data to be used for resource estimations. Further Ora Banda Mining Limited has undertaken extensive infill and confirmation drilling which confirms historical drill results. Sections 1 and 2 describe the work undertaken by Ora Banda Mining Limited and only refer to historical information where appropriate and/or available.
| 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. • Include reference to measures taken to ensure sample retrospectivity 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information |
• Croesus Mining N.L; All samples were dried, crushed and split to obtain a sample less than 3.5kg, and finely pulverised prior to a 50gm charge being collected for analysis by fire assay. • Monarch Gold Mining Company Ltd; Industry standard work. RC samples collected and sent to certified laboratories for crushing, pulverising and assay by fire assay (RC) and aqua regia (RAB). • Pancontinental Mining Ltd; Samples (>2kg) were crushed to 1mm, 1kg split taken and pulverised to 90% minus 20 mesh from which a 50gm aliquot was taken for assay by aqua regia or fire assay. • Consolidated Gold N.L/DPPL (Davyhurst Project PTY. LTD.); Industry standard work, RAB samples crushed, pulverised and a 50g charge taken for fire assay. 200gm soil samples oven dried, and pulverised, 50g charge taken for aqua regia assay. • Riverina Resources Pty Ltd; Industry standard work. RAB samples taken every metre, composited to 4m using a spear. Samples crushed, pulverised and 50g charge taken for fire assay. RC four metre composite samples were collected using a sample spear. RC and diamond samples crushed, pulverised and 50g charge taken for fire assay and/or 4 acid digest. Any gold anomalous 4m composite samples were re-sampled over 1m intervals using a riffle splitter and also sent to Kalgoorlie Assay Laboratory for gold analysis by 50g fire assay. • Barra Resources Ltd; Industry standard work. The entirety of each hole was sampled. Each RC and RAB hole was initially sampled by 4m composites using a spear or scoop. To obtain a representative sample, the entire 1m sample was split using a riffle splitter into a calico bag. Whole diamond core samples for ore zones were sampled. Entire samples were pulverised before splitting and a 50g charge taken for fire assay. • Greater Pacific Gold; Core sampling method unknown, assumed to be cut half core. RC sampling method unknown. Analysis method unknown. However, work completed by accredited laboratories, Analabs and Genalysis. • Carpentaria Exploration Company Pty Ltd; Samples were collected over 1m intervals. 1m, 2m and 4m composite samples taken depending on the rock type. Composite samples were collected using a sample spear. About 2kg samples were despatched for analysis. Samples crushed, pulverised and a 50g charge taken for fire assay. • Malanti Pty Ltd; Industry standard work. 1m samples were collected via a cyclone and passed through a triple splitter giving a 12.5% split of about 2kg. A trowel was used to scoop the samples for composites over 4m and 6m intervals. Samples for assay were then taken with composite intervals based on geology. Many of the single splits were selected for assay in the first instance. Samples packed in poly weave bags were freighted for analysis. Sample crushed, pulverised and a 50g charge taken for fire assay. |
24
| • Riverina Gold Mines NL; Industry standard work, Composited RAB and 1m RC samples assayed by laboratory. Samples crushed, pulverised and a 50g charge taken for aqua regia analysis. • Riverina Gold NL; RAB samples were bulked at 2m intervals. RC holes were sampled at 1m intervals. Diamond core samples were taken at geological boundaries, sample method unknown. All samples crushed, pulverised and a charge taken for fire assay (Au) and perchloric acid digest/AAS for other elements. • Ora Banda Mining Limited (OBM) - 1m RC samples using face sampling hammer with samples collected under cone splitter. 4m composite RC samples collected using a PVC spear from the sample piles at the drill site. For drilling up to April 2020, RC samples were dispatched for pulverising and 50g charge Fire Assay. For drillholes RVRC20036 to RVRC20104 inclusive, 1m and 4m composite samples were dispatched to the lab, crushed to a nominal 3mm, split to 500 grams and analysed by Photon Assay method at MinAnalytical in Kalgoorlie. 4m composite samples with gold values greater than 0.2 g/t Au were re-sampled as 1m split samples and submitted to the lab for Photon Assay analysis. Half-core samples, cut by automated core saw. Core sample intervals selected by geologist and defined by geological boundaries. Samples are crushed, pulverized and a 40g charge is analysed by Fire Assay. For all drilling in 2022, - 1m RC samples using face sampling hammer with samples collected under cone splitter. 4m composite RC samples were taken outside of mineralised zone, collected using a scoop from the sample piles at the drill site. 1m cone spilt samples were taken within the expected mineralised zones. Core sample intervals selected by geologist and defined by geological boundaries. All samples were dispatched to the SGS laboratory at the Davyhurst site for pulverising. Prepared samples were then despatched to SGS laboratories in Kalgoorlie for a 50g charge Fire Assay. Underground diamond drilling - Core sample intervals selected by geologist and defined by geological boundaries. All samples were dispatched to the SGS laboratory at the Davyhurst site for pulverising. Prepared samples were then despatched to SGS laboratories in Kalgoorlie for a 50g charge Fire Assay. Underground face sample (rock chips by hammer) intervals selected by geologist and defined by geological boundaries. All samples were dispatched to the SGS laboratory at the Davyhurst site for pulverising. Prepared samples were then despatched to SGS laboratories in Kalgoorlie for a 50g charge Fire Assay. |

(Examples are discussed below) • Croesus Mining N.L; Auger samples were collected to infill a 250m x 100m grid, Riverina South RAB samples were collected to infill a 400m x 80m grid and Sunraysia RC drilling was completed on a 40m x 200m grid. • Monarch Gold Mining Company Ltd; RAB holes were drilled on 200m x 40m grids and RC holes were drilled on a 20m x 20m and 40m x 20m grids. • Riverina Resources Pty Ltd; Auger soil sampling program was taken over 50m x 50m, 50m x 100m and 50m x 200m spaced grids, Silver Tongue RAB and RC holes were drilled on 25m x 25m, 25m x 50m and 50mx 50m spaced grids and Corporate James RAB holes were drilled on 50m x 100m and 25m x 100m spaced grids. • Barra Resources Ltd; Auger soil sampling program was taken over 50m x 50m, 50m x 100m and 50m x 200m spaced grids, Silver Tongue RAB and RC holes were drilled on 25m x 25m, 25m x 50m and 50m x 50m spaced grids, Corporate James RAB holes were drilled on 50m x 100m and 25m x 100m spaced grids, Forehand RAB and RC holes were drilled on 50m x 100m, 50m x 50m or 25m x 50m spaced grids and Cactus RC holes were drilled on 10m x 10m, 20m x 20m and 40m x50m spaced grids. • Ora Banda Mining Limited (OBM) – underground diamond drilling – typical spacing for grade control purposes is 20m x 20m. Underground face samples are taken each 3m/4m ore development cut. • Drill intercepts are length weighted, 1.0g/t lower cut-off, not top-cut, maximum 2m internal dilution. |
|---|---|---|
| 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 was oriented at 90oto the strike of mineralisation and inclined at 60o. Examples are discussed below. • Croesus Mining N.L; Holes were either vertical or inclined at 60oand oriented towards the west. • Monarch Gold Mining Company Ltd; Holes were inclined at 60o and oriented towards the west. • Consolidated Gold N.L/DPPL; Holes were inclined at 60oand oriented towards either the west or east. • Riverina Resources Pty Ltd; Holes were inclined at 60oand oriented towards either the west or east. • Barra Resources Ltd; Holes were either vertical or inclined at 60oand oriented towards the west. • Greater Pacific Gold; Holes drilled to the east inclined at -58 to -60. Suitable for sub vertical N-S striking mineralisation. • Carpentaria Exploration Company Pty Ltd; Holes were inclined at 60oand oriented towards either the west or east. • Malanti Pty Ltd; Holes were inclined at 60oand oriented towards either the west or east. • Riverina Gold Mines NL; Vacuum holes from RVV1 to RVV69 and from RVV126 to RVV204 were drilled vertically.

RAB and RC holes were inclined at 60oand oriented either east or west. • Riverina Gold NL; RC holes were inclined at 60oand oriented either east or west. • Ora Banda Mining Limited (OBM) – RC drilling is predominately inclined at between -50 and -60 degrees towards the west. Drilling inclined to the east is only done when lodes are deemed to be vertical or if local landforms prevent access. Underground diamond drilling – collared from decline cuddies in sub-horizontal and inclined fans cutting across sub-vertical lodes, holes are designed to optimise intersection angles and reduce bias for Main Lode East and West. Some bias is present for the Murchison lodes, given their close proximity to the drill cuddies and this impact is mitigated through detailed wall/backs mapping of Murchison lode intersections in underground workings and future targeted grade control drilling |

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Drilling, sampling and assay procedures and methods as stated in the database and confirmed from Wamex reports and hard copy records are considered acceptable and to industry standards of the time. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geology of the Riverina area consists of an interlayered sequence of meta-basalts, meta-sediments and ultramafics, rarely cross-cut by narrow pegmatite dykes. The local stratigraphy strikes roughly N-S with primarily steep east to sub-vertical dips. The area has been affected by upper greenschist to lower amphibolite grade metamorphism with many minerals exhibiting strong preferred orientations. All rock units exhibit strain via zones of foliation, with strongly sheared zones more common in ultramafic lithologies. Contemporaneous strike faults and late stage thrust faults have dislocated the stratigraphy and hence, mineralisation. • Gold mineralisation is hosted by quartz-sulphide and quartz-Fe oxide veining primarily in the metabasalts. Metasediments and ultramafics may also contain gold mineralised quartz veining, although much less abundant. Gold mineralisation is also seen in silica-biotite-sulphide and silica-sericite-sulphide alteration zones in the metabasalts. |
| 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: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• See list of drill intercepts. |
36
| 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. • 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. |
• Original assays are length weighted. Grades are not top cut. Lower cut off is nominally 1.0g/t. Due to the narrow nature of mineralisation a minimum sample length of 0.2m was accepted when calculating intercepts. Maximum 2m internal dilution. • Metal equivalents not reported. |
|---|---|---|
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• Intercept widths are down hole lengths. True widths are not reported given the varying orientation of drilling and mineralisation at each deposit/prospect mentioned in the report. • The geometry of the mineralisation at Riverina South is approx. N-S and sub vertical. Surface drilling is oriented perpendicular the strike of the mineralisation. UG drilling from drill cuddy with hole radiating in fans. Holes testing strike extremities are at lower angles to the ore lode and therefore not true widths, while those perpendicular to the lode can approximate true widths. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• See plans, cross-sections and long sections. |

| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Riverina has no known reported metallurgical issues. • Results from previous processing have demonstrated that good gold recovery can be expected from conventional CIL processing methods. • Recent baseline metallurgical test work demonstrated the following gold recoveries: oOxide – 90% oTransitional – 97% oFresh – 94.3% • Additional variation test-work remains ongoing. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Further GC drilling at Riverina underground will continue as the access into the mine is deepened. • Further resource definition drilling will be conducted from the surface, when beyond the reach of the underground drills, aimed and continued mineral resource growth and resource conversion. |

Samples are tracked through the laboratory via their LIMS. • Monarch - Pre-numbered sample bags were put into numbered plastic bags. These numbers were written on the submission forms which were checked by the geologist. Plastic bags were then securely cable tied and placed in a secure location. Samples were then picked up by the Lab in Kalgoorlie or deliver to Perth via courier. A work order conformation was emailed to Monarch personnel for each sample submission once samples were received by the Laboratory. • Ora Banda Mining Limited - Samples were collected on the day of drilling and bagged into cable tied polyweave bags. Polyweave bags are stored into bulka bags on pallets in a secure yard on-site. Once submitted to the laboratories they are stored in cages within a secure fenced compound. Samples are tracked through the laboratoryvia their LIMS. |

Section 2 Reporting of Exploration Results – Missouri & Sand King
(Criteria listed in the preceding Missouri & Sand King section also apply to this section.)
| 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. |
• Sand King deposit is on Tenement M24/960 held by Siberia Mining Corporation Pty. Ltd., a wholly owned subsidiary of Ora Banda Mining. The tenement is in good standing. • .

| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Drilling on the tenements was completed by numerous operators, but the majority of work was completed by WMC, Gilt Edged Mining, Siberia Mining Corporation, Monarch Gold, EGS and OBM. All work by these companies was to industry standards of the time. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• Sand King is an orogenic lode style deposit hosted by mafic rocks, predominantly basalt. • Gold mineralisation at Sand King takes the form of stacked quartz-biotite-feldspar-sulphide shear lodes within the basalt. Widths vary from sub 1m to ~ 6m true width. Occasionally blow outs occur with >6m true width. Mineralised structures are NE-SW striking in the south and normally steeply dipping (~80 degrees) to the north-west while in the north-eastern end of the deposit most mineralisation is interpreted to strike E-W and dip steeply to the north (~80 degrees) |
| 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: oeasting and northing of the drill hole collar |
• See Significant Intercepts in document • The significant intercept table provides details of drill holes with intercepts of >= 1 gram metres, In cases where drilling has intercepted a lode position with grades below this value, NSI (no significant intercept) is listed. This provides context to the number of holes in the project area with significant gold intercepts versus the number of holes with lesser or no significant intercepts. • Widths reported in the Significant Intercepts table are all down hole lengths. |

| 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. • 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. |
• Original assays are length weighted. Grades are not top cut. Lower cut off grade is nominally 1.0g/t. Maximum 2m internal dilution and minimum width of 0.2m. • No metal equivalents reported. |
| Relationship between mineralisatio n widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length,true width not known’). |
• Drilling is predominantly angled at -60oto the south, optimally intersecting the steep north dipping mineralisation. This drill orientation does not intersect all lodes at optimal angles and as such some drill intercepts are longer than true widths. • All intercept widths reported are down hole lengths. The geometry of mineralisation is known for the Sand King deposit. However, no attempt has been made to report true widths. • Some drill programs required shallow angle (~30O) diamond drilling to hit specific targets within the constraints of existing mining infrastructure (existing pit and dumps) |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• See plans and sections. |

| 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 Exploration Results. |
• All drill intercepts from recent drilling are reported. • Results reported include both low and high gram metre (g/t x down hole length) values. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• Metallurgical and geotechnical work has been completed for Sand King deposit in the past. • Additional metallurgical, geotechnical, environmental and engineering work has been or is in the process of being completed for Sand King deposit. |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commerciallysensitive. |
• Additional drilling to grow the UG resource. • UG mining studies. • Statutory approvals for UG mining required. |
