Ø Definitive Feasibility Study on schedule
Ora Banda Mining Limited (ASX:OBM) (“Ora Banda”, “Company”) is pleased to announce the results returned from the Sand King resource model infill validation reverse circulation (RC) and diamond core (DD) drilling program. A total of 16 holes (6 RC and 10 DD) were drilled with a specialised low angle (hole dips to 34 degrees) drill rig to (i) validate ore lode geometry interpretations and gold grade projections; and (ii) further reduce drill hole spacing, in areas near the base of the optimum open pit (designed using a gold price input of A$2,000 per ounce) upon which the current Ore Reserve calculation released to ASX on 30 October 2019 was based.
In summary the drill hole logs and assay results received from these holes have confirmed that both lode geometry and gold grades are in line with inputs and values previously modelled.
The Sand King resource model has been upgraded to include results from this drill program and this upgraded resource model will in turn be used to update the Sand King optimum open pit mine design and Mining Reserve.
All assay results from the Davyhurst Gold Project resource definition drilling program have now been received and delivery of the Definitive Feasibility Study into the restart of mining and processing operations at Davyhurst remains on schedule.
Managing Director Comment
Ora Banda Managing Director, David Quinlivan, said: “it is pleasing to see that the survey and assay results returned from this drill program at Sand King were largely consistent with the pre-drilling expectations of our technical team in terms of both grade and geometry. This outcome has strengthened our confidence in the viability of Sand King as a future open pit gold mine.”

About the Sand King Deposit
Sand King is one of several deposits in the Company’s Siberia project area, which is approximately 37km south east of the Davyhurst processing plant. Historic gold production (1897 to 1930) was spread over numerous reefs in the area. The four largest historically mined reefs where proximal to a regionally significant mafic and ultramafic contact. There are a number of other prospects in the area, the most significant of which are the Pearling Grounds and the Sand King North. All of these occurrences fall with a mineralised corridor that sits within mafic lithologies bounded by granites in the west and ultramafic in the east (see Figure 1).
Modern mining has concentrated on four open pits, namely Sand King, Missouri, Palmerston-Camperdown and Bewick - Moreing. These deposits are hosted entirely within the mafic basalts, west of the contact and remain open at depth. Sand King is the largest producer of these deposits having mined approximately 747,000t @ 4.0 g/t for 88,000 ounces* between 1980 and 1991.
The Sand King deposit has a current Mineral Resource of 2.45 Mt @ 3.4 g/t Au for 268,000 ounces (see ASX Announcement dated 3 January 2017) and is one of five key priority mining targets at the Davyhurst Project.
The Open Pit Mining Reserve estimate for the Sand King deposits is 1,100,000t at a grade of 2.6 g/t Au for 93,000 ounces Au (see ASX Announcement dated 12 November 2019). The relatively high reserve grade makes Sand King an attractive development target.

JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE
Section 1 Sampling Techniques and Data
Information for historical (Pre Ora Banda Mining Limited from 1980’s to 2010) 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 confirm 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 listed in the preceding section also apply to this section.)
Criteria JORC Code explanation Commentary
| 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 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. |
• Goldfields Group; Auger holes were drilled to a maximum depth of 1.5m. RC samples were routinely collected at 1m intervals. Diamond drill core samples were taken at geological boundaries and sawn in half. Samples pulverised at laboratory. • Monarch Gold Mining Company Ltd; RAB samples were collected at 2m and 4m composites via a scoop method at 1m intervals.

| repeats (1 in 20) were used during the first phase drilling campaign to provide a reference to the internal lab standards. There was a strong correlation between standard (client) and laboratory results. Repeats of composite samples showed no problems with technique or dependability with the laboratory. • EGL& Swan; Samples were sent to Intertek Assay Laboratories to be analysed for gold by 50gm fire assay. Certified reference material standards were employed for a gold range of 0.32 to 48.55ppm. Blanks were also employed. Satisfactory results were obtained for both. Field duplicates were routinely taken from RC sampling. • Ora Banda Mining Limited - Samples sent to SGS, Kalgoorlie. The samples have been analysed by firing a 50gm portion of the sample. This is the classical fire assay process and will give total separation of gold. An ICPOES finish is used. Commercially prepared standard samples and blanks are inserted in the sample stream at a rate of 1:20 for standards and 1:20 for blanks. Sizing results (percentage of pulverised sample passing a 75μm mesh) are undertaken on approximately 1 in 40 samples. Duplicate samples are taken in RC drillholes at a rate of approximately 1:30. The accuracy (standards) and precision (repeats) of assaying are acceptable. |

| 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. • Whether sample compositing has been applied. |
• Drilling is predominantly on a 20mE X 20mN grid. • At Sand King the data spacing and distribution is sufficient to establish geological and grade continuity to support the definition of Mineral Resource and classifications as defined under the JORC 2012 code. • Samples are not composited for reporting. • Samples are composited for resource calculations. |
| 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. |
• At Sandking drilling is predominantly inclined to the south, optimal for the predominantly ENE • striking, north dipping mineralisation. • It is not known whether there is any introduced sample bias due to drill orientation. |
| Sample security |
• The measures taken to ensure sample security. |
• Unknown for earlier operators. • EGL – Samples are bagged, tied and 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 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 laboratory via their LIMS. |
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
• Digital data from the SQL database has been reviewed by EGL and is consistent with hard copy and digital WAMEX data. • Siberia Mining Corporation conducted a due diligence on the data and core in 2005 and were “comfortable with the quality and integrity of the data”. Digital data has been reviewed and is consistent with hard copy data. • Monarch Gold MiningCompanyLtd;Monthly QAQC reports wereproduced to monitor accuracyandprecision. |
