Further to Ora Banda Mining Limited’s (ASX: OBM) (“Ora Banda”, “Company”) Operational Update of 27 May, the Company is pleased to announce the following assay results for the Golden Eagle deposit. Golden Eagle is located 3.2 km from the Davyhurst processing plant (Figure 1) and is an integral part of the Company’s Davyhurst Gold Project (“Project”).
These results follow other previously announced drilling results that included GEDD21008 - 10.5m @ 7.6 g/t Au, GEDD21009 - 6.1m @ 4.5 g/t Au & GEDD21003 - 3.4m @ 7.5 g/t Au (see ASX announcement dated 30 April 2021).
Golden Eagle underground diamond drilling was aimed at infilling and extending the declared mineral resource of 393kt @ 3.9g/t Au for 49,000 ounces (Appendix 1) . The drilling continues to support premining expectations for the North Shoot and provides important geological information into the remodelling of the Southern Mining Area (Figure 2).
Managing Director Comment
Ora Banda Managing Director, David Quinlivan, said: “We are currently developing northwards on the 310 Level towards some of these very strong results (19m @ 5.4g/t Au & 14.0m @ 4.8g/t Au) and are certainly looking forward to mining this high grade area in the near term.
The Southern Mining Area has also yielded some strong results which our geology team are currently remodelling. The flatter folded ore lode geometry in this area is a new and potentially significant development and we are currently looking at ways to better target this flatter ore zone in future mining programs.”
The Golden Eagle underground diamond drilling program commenced in late February 2021 and was completed in April 2021. A total of 61 holes were drilled for 8,370 metres. Currently, assay results for 17 holes totalling 2,445 metres remains outstanding.

About the Golden Eagle Underground Mine
Golden Eagle deposit is one of five priority mining targets at the Davyhurst Project and is 3.2 km from the Davyhurst processing plant. Western Mining Corporation (WMC) commenced open pit mining at Golden Eagle in 1986 and produced 864kt @2.6g/t Au for 73,000 ounces. A further 39,000 ounces were produced by Croesus Mining between November 2000 and December 2003*.
OBM initially updated the Golden Eagle mineral resource on 8 April 2020 following the collation of surface drilling, underground drilling that was conducted in April 2018 and updates that included all face sampling data that was collected from previous ore drive development. All technical and geological information available for the deposit was combined into an updated geologically based mineralisation model. This in turn formed the basis of the updated resource estimation.
The upgraded Golden Eagle Resource is 393kt @ 3.9 g/t Au for 49,000 ounces, which includes an Indicated Resource of 247kt @ 4.1 g/t Au for 33,000 ounces . The Golden Eagle Ore Reserve was declared on the 30 June 2020 for 130kt @ 3.8 g/t Au for 16,000 ounces.
OBM commenced underground mining at Golden Eagle in the March quarter 2021 with capital decline development currently below the 310 Level (approximately 150 metres below the natural surface). Ore development spans five working levels, namely the 395 Level to the 310 Level (approximately 100 vertical metres). Stoping has been completed on two levels (395 & 375 Level) and remains ongoing on two levels (355 & 335 Level).
Mining completed to date on the North Shoot has met the DFS expectations. Mining in the Southern Mining Area has encountered, folded ore lodes (Figure 3) e.g., an asymmetrical anticline with a flat west limb and a moderately dipping east limb, that require more work to better understand the controls on gold mineralisation. This is a positive result but a better understanding of gold distribution within the folded sequence is needed.
Consequently, drilling, mapping and additional mine development are being undertaken to better understand gold distribution within the folded lodes. Currently, it has been traced down-plunge for more than 100 metres and it’s highly likely it proves to be continuous for some distance yet. The grade potential of the folded lodes remains strong with a number of drill holes intersecting what appears to be a highgrade core area (Figure 2).
The folded sequence presents as a relatively limited drill target due to its orientations to the principal drilling direction. As a result, it may be under-represented in the current drilling data. Additional long range drilling programs will be developed to test the greater extents and continuations of this folded sequence.

Notes:
-
The table contains rounding adjustments to two significant figures and does not total exactly.
-
This Ore Reserve was estimated from practical mining envelopes and the application of modifying factors for mining dilution and ore loss.
-
For the open pit Ore Reserve dilution skins were applied to the undiluted LUC Mineral Resource estimate at zero grade. The in-pit global dilution is estimated to be 29% at Sand King, 43% at Missouri, 22% at Riverina, 13% at Waihi and 23% at Callion all of which were applied at zero grade. The lower dilution at Riverina, Waihi and Callion reflecting the softer lode boundary and allows for inherent dilution within the lode wireframe. All Inferred Mineral Resources were considered as waste at zero grade.
-
The Open Pit Ore Reserve was estimated using incremental cut-off grades specific to location and weathering classification. They range from 0.54 g/t to 0.69 g/t Au and are based on a price of A$2100 per ounce and include ore transport, processing, site overheads and selling costs and allow for process recovery specific to the location and domain and which range from 85% (Sand King fresh ore) to 95%.
-
Approximately 100,000 t at 1.8 g/t at Riverina was downgraded from Proved to Probable due to uncertainty at the time surrounding metallurgical recovery. Subsequent test work estimated the Riverina recoveries to be 90.1%, 97.6% and 94.3% for oxide, transition and fresh, respectively.
-
The underground Ore Reserve was estimated from practical mining envelopes derived from expanded wireframes to allow for unplanned dilution. A miscellaneous unplanned dilution factor of 5% at zero grade was also included. The global dilution factor was estimated to be 32% with an average grade of 0.77 g/t Au.
-
The underground Ore Reserve was estimated using stoping cut-off of 2.7 g/t Au which allows for ore drive development, stoping and downstream costs such as ore haulage, processing, site overheads and selling costs. An incremental cut-off grade of 0.7 g/t Au was applied to ore drive development and considers downstream costs only. Cut-off grades were derived from a base price of A$2100 per ounce and allow for an assumed process recovery of 92%. Subsequent test work estimated the Golden Eagle fresh recovery to be 90.6%.

Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut |
• Aberfoyle/Bardoc - RC and RAB sampling methods generally unknown however usually collected as 1m samples and composited to 2 to 4m samples when outside mineralised zones. Pre-1990 RAB holes generally sampled on 2-3m intervals and composited to 6m. Samples sent to accredited laboratories for drying, crushing and pulverising. Usually 50g fire assay for RC samples and aqua regia or 50g fire assay for RAB samples. • Consolidated Gold (Cons Gold) \ Consex– RC 1m samples where alteration is visible. Remainder of hole composited to 4m. 2 to 3 kg samples, including core, sent to laboratory for crushing, pulverising and 50g Fire Assay. • Croesus – RC 1m samples collected under cyclone. 5m comps assayed for gold by 50g Fire assay. NQ diamond except for geotechnical purposes (HQ triple). • Davyhurst Project Pty. Ltd (DPPL) - 4.25 to 5.5 inch RC drilling with face hammer. Potential mineralisation sampled and assayed on a metre basis otherwise 4m composites. Samples jaw crushed and pulverised before taking a 50gm charge for fire assay. • Billiton - RAB and RC 1m samples with RAB being composited to 2m. Diamond core of NQ size. Laboratory and analysis methods unknown. • Eastern Goldfields Limited (EGS) –Half core sample intervals selected by geologist and defined by geological boundaries. Samples are crushed, pulverized and a 50g charge is analysed by Fire Assay. Underground RC samples were taken every 1m and analysed as above. • Eastern Goldfields Limited (EGS)- Face Samples oThe face dataset is channel sampling across the development drives. Each sample is a minimum of 1 kg in weight. Sample weights average 3-5kg depending on the sample length. Face sampling is conducted linear across the face at approximately 1.5 metres from the floor. The face is sampled from left to right in intervals no larger than 1.0 metre. Minimum ore sample width is 30 cm. oThe ore vein is determined by its general angle to north(local grid north, ore veins are roughly due north in local grid), textural difference to non-mineralised veins (non-ore veins are straighter have no local foliation and lack multiple layering), and associated mineralised minerals (pyrite, Pyrrhotite, arsenopyrite) • WMC - RC Sampling on 1m basis, assayed by aqua regia method, unknown laboratory. • SWAN – As for EGS • OBM – As for EGS |
| 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 (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. |

• Aberfoyle/Bardoc – Diamond core sawn in half. RC and RAB samples with variable compositing lengths and often 1m samples. Method unknown before 1992, but thereafter riffle split to approximately 2kg samples. RC and RAB were usually prepared by single stage mixer and grind. Diamond, when known was jaw crushed and ring milled for a 50g charge fire assay. Sample duplicate studies undertaken at times, usually with good correlation • Cons Gold \Conex- RC Samples collected via cyclone at 1m intervals and passed through 3 stage riffle splitter. A 2-3kg fraction was calico bagged for analysis, the residue collected in plastic bags and stored on site. Potentially mineralised zones were sampled at 1m intervals, the remainder composited to 4m by unknown method. Composite samples returning >0.19g/t were re submitted at 1m intervals. Samples underwent mixermill preparation (2-3kg) by Amdel Laboratories. RAB 4m composite samples using PVC spear. Samples returning >0.19g/t were re submitted at 1m intervals. Diamond drill samples were sawn into half core. One half was jaw crushed, then pulverised using a labtechnics mill. A quartz blank was pulverised between each sample to avoid contamination. Field duplicates from residues at 1 in 20 frequency submitted. • Croesus RC/RAB - 1m samples collected under cyclone. 5m comps, spear sampled with 50mm PVC pipe. Wet RC drill samples were thoroughly mixed in the sample retention bag and scoop sampled to form a composite sample. 3-5kg five metre composite analytical samples, returning values greater than 0.1g/t gold, were riffle split at 1m intervals, were samples where dry, and grab sampled where wet. RAB 1m resampling method unknown. Samples were dried, crushed and split to obtain a sample less than 3.5kg, and then fine pulverised prior to a 50gm charge being collected and analysed. Every 20th sample was duplicated in the field and submitted for analysis. Diamond tails were cut to half core and sampled based on geological boundaries and identified prospective zones. Samples size varied from 0.2m to1m. Core samples were sent to Ultratrace Laboratories of Perth |

• Aberfoyle/Bardoc – multiple analysis methods at Sheen, Amdel, Genalysis, Classic, Comlabs and Australian Laboratories. Usually 50g fire assay for RC and aqua regia or 50g fire assay for RAB. Quality control procedures unknown. • Cons Gold/DPPL – RC and RAB - Mixermill prep with fire assay 50g charge at AMDEL, Minilab or Analabs Laboratories in Kalgoorlie. Half core was diamond sawn, jaw crushed, milled using LABTECHNICS mill at AMDEL for 50g charge by fire assay. Gannet standards submitted to monitor lab accuracy for infill resource drilling. Pulp umpire analysis was done but frequency unknown (1995). Screen fire assays of selected high grade samples. Quartz blanks submitted between each diamond sample • Croesus - Samples analysed for Au by Fire Assay/ICPOES by Ultratrace in Perth.

| Data spacing and distribution |
• Data spacing for reporting of Exploration |
• Drill hole spacing is adequate to establish geological and grade continuity for the Golden Eagle deposit which has a JORC (2004) compliant reported resource. • Sample compositing has only been undertaken for resource modelling purposes. • Drill intercepts are length weighted, 1g/t lower cut-off, not top-cut, maximum 2m internal dilution. • Close spaced face samples (single line sample every 2.5 to 3.0m) and face and backs geological mapping provide detailed high density dataset to enable Grade Control models for mine planning. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding 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. |
• All current drilling by OBM is located on tenement M30/255. • M30/255 is held by Carnegie Gold PTY LTD, a wholly owned subsidiary of Ora Banda Mining LTD. (OBM) • The tenement is not subject to joint ventures, partnerships or 3rd party royalties. • There are no known heritage or native title issues. • There are no known impediments to obtaining a licence to operate in the area. |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• The deposit was originally discovered in the early 1900’s. • WMC developed an open pit at the Golden Eagle deposit in 1986 and was previously last mined by Croesus in 2005. • The Golden Eagle deposit occurs within a regionally extensive amphibolite unit which also hosts a number of other gold deposits at the Davyhurst Project (LOI, etc). The Gold mineralisation occurs within steeply west dipping shear zones, comprising strongly foliated biotite-quartz schist, with localised quartz-feldspar lode (QFL), and disseminated and banded sulfides (py, po). The ore structure is characterised by biotite alteration which contrasts from surrounding waste rock which is characterised by Chloritic alteration. • All companies listed conducted multiple drilling programs and produced several reports on the deposit in their time. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The LOI & Makai, Golden Eagle Deposits and Great Ophir are hosted within approximate 30-50 metres wide biotite schist that frequently contains a silica dominant Quartz-feldspar lode (QFL) situated near the base of the schist. Historically this biotite schist has been defined as metamorphosed inter-flow laminated meta-sediment of siliceous, calc-silicate and pelitic compositions (Amdel, May 1993) while the QFL is interpreted to originally have been a laminated silica rich sediment, although this assessment has been made on overall composition as no relict features remain. The surrounded rocks are predominately high-Mg basalt that along with the interflow sediment have undergone Amphibolite grade metamorphism. These units are bound to the east and west by large scale faults. • These deposits appear to have formed along the intersection of the biotite schist and a shallow NE dipping fault with the development of plunging shoots of (-20O-> 357o) within the biotite schist at LOI and Golden Eagle. |
| 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 whythis is the case. |
||
| 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 clearlystated. |
• No upper cut applied to reported drill hole results, significant intersections are reported as weighted averages, greater than 1g/t, 2m maximum internal waste, • The mineralisation in the Lights of Israel Complex and Golden Eagle is hosted by broad biotite schist with a high grade Quartz Feldspar Lode (QFL) located at the base of the schist. When present the QFL has been used to define the edge of high grade mineralised intercepts, where done this is clearly labelled. • No upper cut applied to reported face sample results, significant intersections are reported as weighted averages, greater than 2.5g/t and no more than 1metre of internal dilution. |
| 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’). |
• All intercept lengths reported are downhole lengths, not true widths. • The majority of the reported historical surface drilling at Golden Eagle was inclined (generally -60o), with steep dipping mineralisation, this results in intersection angles of between 40 and 60 degrees, as such downhole intercepts are 15-35% wider than true width. • Face samples are taken normal to the strike of the orebody, hence can be considered true width. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• Refer to diagrams in 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 reportingof Exploration Results. |
• The LOI Complex, including Golden Eagle, has undergone significant drilling over the years and as such reporting of all results is not practicable. Results that have been deemed to bear influence on the new EGS results have been reported in this announcement to ensure representivity of the results. |
| 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. |
• All exploration data believed to be meaningful and material to this release has been included |
| 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. |
• Additional drilling from underground positions is planned for Golden Eagle, as mentioned in the text of this announcement. |
