Announcement PDF resourcing the new economy for a better tomorrow REGISTERED OFFICE: Suite 2, Level 11, 385 Bourke Street, Melbourne, VIC 3000 PRINCIPAL PLACE OF BUSINESS: 6888 Mulligan Highway, Mt Carbine Qld 4871 POSTAL ADDRESS: PO Box 1496, Mareeba Qld 4880 ABN: 77 115 009 106 (ASX: EQR) T: (07) 4094 3072 | F: (07) 4094 3036 | W: eqresources.com.au 28 April 2026 CLARIFICATION ANNOUNCEMENT – NON COMPLIANCE WITH ASX LISTING RULE 5.12 EQ Resources Ltd is a global tungsten producer with mining activities in Australia and Spain. EQ Resources Limited (ASX: EQR) (“EQR” or “the Company”) advises that the Company has become aware of an inadvertent breach of Listing Rule 5.12 in relation to its announcements starting with EQR Identifies 5 Exploration Targets for Wolfram Camp released on 7 October 2024, and then subsequently referenced in EQ Resources Limited Annual Report 2024, EQR Noosa Conference Investor Presentation released on 24 July 2025, EQR Progresses Regional Tungsten Hub Strategy Announcement 18 June 2025, EQR Investor Presentation on 5 September 2025, Updated Investor Presentation 22 October 2025, EQ Resources Annual Report 2025, and Investor Presentation-Euroz Hartleys Conference released on 18 March 2026. Listing Rule 5.12 requires the Company, when reporting historical estimates relating to a material mining project, to include certain information in the market announcement, which is stated below and should be read together with all announcements referenced above and all future announcements relating to the Wolfram Camp Project: The historic resource estimate for the Wolfram Camp Mine Exploration Permit Minerals RA442 licence, is a historic estimate and not in accordance with the JORC Code. The Company notes that the estimate and historic drilling results from programs completed in 2012-2015 are reported in accordance with NI 43-101, by Qualified Person Adam Wheeler, as attached to the announcement (NI 43-101 Estimate). A Competent Person has not done sufficient work to classify the NI 43-101 Estimate as JORC Code Mineral Resources or JORC Code Ore Reserves (as relevant) in accordance with the JORC Code 2012. As such the mineral resources and mineral reserve estimates within the NI 43-101 Estimate are classified as ‘foreign estimates’ under the ASX Listing Rules. In accordance with ASX Listing Rule 5.12, EQR provides additional information in relation to these foreign estimates in Schedule 1 below. It is uncertain that following evaluation or further exploration work that the NI 43-101 Estimate will be able to be reported as Mineral Resources or Ore Reserves in accordance with the JORC Code. It is possible that following further evaluation and/or exploration work that the confidence in NI 43-101 Estimate may be reduced when reported under the JORC Code 2012. Nothing has come to the attention of the Company that causes it to question the accuracy or reliability of the NI 43-101 Estimate, but the Company has not independently validated this estimate and therefore it is not to be regarded as reporting, adopting or endorsing these estimates. The Company apologises for the oversight and reaffirms its commitment to full compliance with the ASX Listing Rules and to maintaining high standards of corporate governance. SCHEDULE 1 ASX LISTING RULE EQR RESPONSE 5.12 Subject to rule 5.13, an entity reporting historical estimates or foreign estimates of mineralisation in relation to a material mining project must include all of the following See sections below for information regarding the historic estimate. resourcing the new economy for a better tomorrow Page 2 information in a market announcement and give it to ASX for release to the market 5.12.1 The source and date of the historical estimates or foreign estimates The NI 43-101 Estimate was prepared by Qualified Person (as defined in the Canadian NI 43-101 Standards), Adam Wheeler, who was an independent mining consultant based at Cambrose Farm, Redruth, Cornwall, England at the date of the Report. The Canadian NI 43-101 Standard is a national instrument for the Standards of Disclosure for Mineral Projects within Canada. These foreign estimates are the most recent Mineral Reserve and Mineral Resource estimates for the Wolfram Camp Project. 5.12.2 Whether the historical estimates or foreign estimates use categories of mineralisation other than those defined in Appendix 5A (JORC Code) and if so, an explanation of the differences The NI 43-101 Estimate was prepared using the Canadian NI 43-101 reporting guidelines. EQR believes that the categories of mineralisation reported under Canadian NI 43-101 Standards are similar to the JORC Code 2012 categories. EQR considers the foreign estimate to be NI 43-101 compliant. EQR considers that the foreign estimates are sufficiently reliable and consistent with current industry standard estimation methodologies as generally appropriate for Mineral Resource and Ore Reserve estimation. The Mineral Resource estimate contains categories of NI 43-101 ‘Measured’, ‘Indicated’ and ‘Inferred’, that are consistent with the terminology of the Measured’, ‘Indicated’ and ‘Inferred’ under the JORC Code 2012. NI 43-101 Mineral Reserves are reported as Proven and Probable in the foreign estimate. These classifications are consistent with definitions of Proved and Probable Ore Reserves in the JORC Code 2012. 5.12.3 The relevance and materiality of the historical estimates or foreign estimates to the entity EQR intends to commence a drilling program in FY27 at Wolfram Camp Project. Once the results of this drilling program are completed, EQR then will be in a position to determine how material these estimates are and whether the estimates can be considered within the definition of JORC Code 2012 compliant resources. It is not certain that further evaluation and/or exploration work will define resources or ore reserves. 5.12.4 The reliability of the historical estimates or foreign estimates, including by reference to any of the criteria in Table 1 of Appendix 5A (JORC Code) which are relevant to understanding the reliability of the historical estimates or foreign estimates The NI 43-101 Estimate is considered to be reliable by EQR for the following reasons: • The foreign estimate was prepared in accordance with Canadian National Instrument 43-101 (NI 43-101) and the CIM Definition Standards, which are internationally recognised reporting standards broadly comparable with the JORC Code in respect of transparency, materiality and competence. • The foreign estimate is documented in the technical report titled “Technical Report on the Mineral Resource and Reserves of the Wolfram Camp Mine Project” dated 31 October 2015, which was prepared by a Qualified Person in accordance with NI 43-101. The Qualified Person has accepted responsibility for the underlying data, geological interpretation and estimation methodology, and has confirmed that the work satisfies the due diligence, verification and professional care requirements of NI 43-101. • The Qualified Person was independent of the previous owner of the Wolfram Camp Project, which supports the objectivity of the estimation process and the conclusions reached. EQR has undertaken a review of the foreign estimate and the supporting technical information available to it, including geological data, drilling and sampling information (to the extent available), historical mining records and site inspections. Based on this review, resourcing the new economy for a better tomorrow Page 3 EQR considers that the assumptions, parameters, modifying factors and estimation methodologies adopted in the foreign estimate are reasonable in the context of the style of mineralisation and the mining methods contemplated. Completed Table 1 of Appendix 5A (JORC Code) below provides additional clarification & information. EQR considers that the geological setting, mineralisation style and historical mining performance at Wolfram Camp are consistent with the framework described in the foreign estimate, and do not indicate any material inconsistencies that would invalidate reliance on that estimate as a foreign estimate. The drilling, sampling, assaying, database compilation and estimation practices described in the NI 43- 101 report are considered by EQR to be consistent with industry practice at the time the work was undertaken and are of a standard sufficient to support the foreign estimate. EQR is not aware of any material information that materially conflicts with the foreign estimate, nor any matter that would cause it to conclude that the foreign estimate is unreliable as a statement of the mineralisation at the time it was prepared. Notwithstanding the above, a Competent Person has not done sufficient work to classify the foreign estimate as a Mineral Resource or Ore Reserve in accordance with the JORC Code (2012). Accordingly, the foreign estimate should not be regarded as a Mineral Resource or Ore Reserve reported in accordance with the JORC Code, and it remains uncertain that, following further evaluation and/or exploration work, the foreign estimate will be able to be reported as a Mineral Resource or Ore Reserve in accordance with the JORC Code. 5.12.5 To the extent known, a summary of the work programs on which the historical estimates or foreign estimates are based and a summary of the key assumptions, mining and processing parameters and methods used to prepare the historical estimates or foreign estimates The foreign estimate for the Wolfram Camp Project is based on historical exploration and mining activities undertaken by previous operators, as compiled in the NI 43-101 Estimate. Work programs supporting the estimate include diamond and reverse circulation drilling, underground development and sampling, surface trenching, and geological mapping of greisen-hosted tungsten mineralisation. Drilling density varies across the deposit, with closer spacing in historically mined areas. Sampling is understood to comprise diamond core and RC drilling, with assays for WO₃ determined using industry standard analytical techniques. More recent programs incorporated QA/QC procedures including standards, blanks, and duplicates; however, earlier historical QA/QC data is incomplete and has not been independently verified by EQR. The estimate is reported to have been prepared using three- dimensional geological modelling and block modelling techniques with grade interpolation by industry standard methods. Classification was based on drill spacing, geological continuity, and data confidence, although detailed estimation parameters have not been independently verified. Key assumptions include the application of cut-off grades based on economic parameters at the time of reporting (typically in the order of 0.05%–0.10% WO₃), bulk density assumptions consistent with greisen mineralisation (approximately 2.6–2.8 t/m³), and tungsten resourcing the new economy for a better tomorrow Page 4 price assumptions aligned with prevailing ammonium paratungstate (APT) prices at the time. Mining assumptions are understood to reflect open pit extraction methods consistent with historical operations at Wolfram Camp, with potential for underground mining in deeper zones. Processing assumptions are based on conventional gravity concentration methods, supported by historical plant performance, with typical tungsten recoveries in the range of approximately 60% to 75%. EQR has not undertaken sufficient work to independently verify the work programs, assumptions, or estimation methodology underpinning the foreign estimate, and there remains uncertainty regarding the reliability of certain historical data inputs. 5.12.6 Any more recent estimates or data relevant to the reported mineralisation available to the entity As at the date of this announcement, the foreign estimates reported in the Report have not been superseded by any later estimates. No more recent estimates have been completed or provided to EQR. 5.21.7 The evaluation and/or exploration work that needs to be completed to verify the historical estimates or foreign estimates as Mineral Resources or Ore Reserves in accordance with ASX Listing Rules Appendix 5A (JORC Code). EQR intends to commence a drilling program in FY27 at Wolfram Camp Project. After conclusion of this programme, it proposes to undertake an evaluation of the data available to seek to verify the foreign estimate as Mineral Resources or Ore Reserves in accordance with the JORC Code. This evaluation will involve the full verification of all information and applicable modifying factors used in estimates in the Report, together with the addition of information and results from the drilling program. External consultants will be used as required. 5.12.8 The proposed timing of any evaluation and/or exploration work that the entity intends to undertake and a comment on how the entity intends to fund that work The evaluation work is planned to be completed during FY27. Funding for this work will be from internal cash flows. 5.12.9 A cautionary statement proximate to, and with equal prominence as, the reported historical estimates or foreign estimates stating that: The estimates are historical estimates or foreign estimates and are not reported in accordance with the JORC Code EQR cautions that the NI 43-101 Estimate is not reported in accordance with the JORC Code 2012. A Competent Person has not yet completed sufficient work to classify the NI 43-101 Estimates as JORC Code Mineral Resources or JORC Code Ore Reserves in accordance with the JORC Code 2012. It is uncertain that following evaluation and/or further exploration work that the NI 43-101 Estimate will be able to be reported as Mineral Resource or Ore Reserves in accordance with the JORC Code. Nothing has come to the attention of EQR that causes it to question the accuracy or reliability of the NI 43- 101 Estimate, but EQR has not independently validated those estimates and therefore EQR is not to be regarded as reporting, adopting or endorsing those estimates. 5.12.10 A statement by a named competent person or persons that the information in the market announcement provided under rules 5.12.2 to 5.12.7 is an accurate representation of the available data and studies for the material mining project. The statement must include the information referred to in rule 5.22 (b) and (c). Mr Tony Bainbridge is the Competent Person for this announcement. The following statement has been included in the Competent Person section: The information in this statement that relates to exploration results, mineral resources or ore reserves is based on information compiled by Tony Bainbridge, who is a Member of the Australasian Institute of Mining and Metallurgy (AusIMM No. 112770). Mr Bainbridge is engaged as a contractor to EQ Resources Ltd and is therefore not independent within the meaning of the JORC Code (2012). Mr Bainbridge has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the ‘Australian Code for Reporting resourcing the new economy for a better tomorrow Page 5 Exploration Results, Mineral Resources and Ore Reserves’ (the JORC Code). Mr Bainbridge consents to the inclusion of this information in the form and context in which it appears in this statement. resourcing the new economy for a better tomorrow REGISTERED OFFICE: Suite 2, Level 11, 385 Bourke Street, Melbourne, VIC 3000 PRINCIPAL PLACE OF BUSINESS: 6888 Mulligan Highway, Mt Carbine Qld 4871 POSTAL ADDRESS: PO Box 1496, Mareeba Qld 4880 ABN: 77 115 009 106 (ASX: EQR) T: (07) 4094 3072 | F: (07) 4094 3036 | W: eqresources.com.au Table 1 Appendix 5A (JORC Code) 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. • 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. • The Wolfram Camp Mine Project has been sampled by a mixture of diamond (including PQ and HQ) drill holes and Reverse Circulation percussion (‘RC’) drill holes. Blasthole exploration (BEX) holes and grade control (GC) drilling have also been completed. • Queensland Ore Limited (QOL) In the main, QOL sampled its diamond holes on geological or mineral boundaries such that most intersections sent for assay were less than 1m. The RC samples were taken via a cyclone at 1m intervals. All samples other than sediments were riffle split to produce a +/-2kg sample for analysis. • Planet Metals Limited (PML) Core sampling was based on ½ core sampling, with limited selective sampling; as a consequence of the very spotty nature of the wolfram and molybdenum mineralisation the core was cut in such a way as to bisect the mineralisation with ideally equal portions being present on each half of the core. All samples were assayed for W, Mo, Bi, As and Sn using the ME- XRF05 method; where samples exceeded the detection limits for that method, they were re-assayed using the ME-XRF15c method. For RC drilling PML used a riffle splitter to collect a 2-3kg sample. Drill holes were sampled predominantly over 1m intervals. resourcing the new economy for a better tomorrow Page 7 Criteria JORC Code explanation Commentary • Wolfram Camp Mining (WCM) Open pit blasthole samples from grade control drilling results have assays for W, Mo, Bi, As and Fe. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). • A limited amount of drilling may have been carried out before the 1970s and although data exists for surface and underground drilling completed in the 1970s, there are no detailed records of this work. The various drilling programs completed at Wolfram Camp since the 1970s are summarised below; in terms of diamond drillholes (DD) and reverse circulation (RC) drillholes, stemming from exploration work done by previous owners between 1995-2010, as well as blasthole exploration samples (BEX) completed by Almonty since 2014: • 1981-82, Tenneco Oil and Minerals (Tenneco) – 12 DD holes. • 1994-96, Allegiance Mining NL (Allegiance) – 37 RC holes. • 2005-06, Queensland Ore Limited (QOL) – 163 holes, mostly RC. • 2010, Planet Metals Limited (PML) - 200 holes, mostly RC. • 2014-15, Almonty – 1,417 BEX holes (generally 25m in length). • 2012-present, Wolfram Camp Mining (WCM) - 55,195 grade control (GC) holes • Queensland Ore Limited (QOL) During June to December 2005, QOL drilled 36 diamond drillholes in for a total of 2437.8m. Holes were collared in PQ (providing a nominal 85mm core) and reduced to HQ (providing a nominal 63.5mm core) once ground conditions were considered suitable. In December 2005, 15 (RC) holes were drilled for a total of 939m and a further 112 RC holes totalling 5,357m between April and December 2006, using a 4.5” (114mm) bit. • Planet Metals Limited (PML) PML drilled 200 holes comprising 45 DD totalling 2,269m and 155 RC holes totalling 2,571m between September 2009 and February 2010. • Almonty Industries Inc (Almonty) Since 2014 Almonty has completed 1,417 blasthole exploration (BEX) holes completed covering 36,092m. resourcing the new economy for a better tomorrow Page 8 Criteria JORC Code explanation Commentary • Wolfram Camp Mining (WCM) Since restart of the mine in 2012, grade control (GC) drilling results have been accumulated from open pit blasthole samples. This database now consists of data from 55,195 GC holes, covering over 321km of drilling. 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. • QOL – Drilling All core was transferred directly from the core barrel to correctly sized aluminium core trays at the rig site. Wooden core blocks were placed in the trays to record downhole depths at the end of each drill run. At intervals the core trays were carefully transported to a centralised core handling area. Excellent sample recovery was noted for the RC drilling programs. • PML – Drilling Sample recovery in the mineralised zone is believed to be high for PML RC drill holes. 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. • QOL – Logging Core was geologically logged by either company geological staff or experienced geological consultants. Alpha angles were measured throughout of any contacts or major discontinuities in the core, and where successful core orientation was achieved, beta angles were also measured. Basic geotechnical logging was carried out with Rock Quality Designation (RQD) factors calculated for all core. • PML – Logging Drill core samples were put into core trays and transported from the drill site to the sample preparation shed where they were marked up and logged. A geological and geotechnical log was completed for each of the holes. The geological logging system used by PML was similar to that used by the previous owners of the Wolfram Mine tenements. A sample from each 1m RC interval was put in a numbered chip tray which was then photographed and each 1m sample was logged. Sub-sampling techniques • 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 • QOL Sampling All core was transferred directly from the core barrel to correctly sized aluminium core trays at the rig site. Wooden core blocks were placed resourcing the new economy for a better tomorrow Page 9 Criteria JORC Code explanation Commentary and sample preparation 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 representivity of samples. • 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. in the trays to record downhole depths at the end of each drill run. At intervals the core trays were carefully transported to a centralised core handling area. Core samples were selected by geological logging and sawn such that one quarter core was sent to the laboratory. Sample intervals were selected on geological criteria, with the maximum sample length (other than two samples) of one metre. A sample collection method was introduced whereby the same progressive quarter core was selected for all intervals, irrespective of the distribution of mineralisation within the whole core, to eradicate any sampling bias. Core samples were transported to ALS Chemex’s laboratory in Townsville where sample preparation was carried out. All samples were weighed, dried and crushed (two passes) to a nominal 6mm. Samples containing coarse molybdenite which had been identified by QOL were spread on to a plastic mat and the coarse molybdenite was hand picked, weighed and bagged. The remainder of these samples, and the whole of the other samples, were individually pulverised to 85% passing 75microns. A 300gm extract from each sample was sent to ALS Chemex’s Brisbane laboratory. With the coarse molybdenite samples, the weight of the hand-picked molybdenite was converted to Mo (multiplied by 0.5994), and this weight of Mo was divided by the original weight of the sample times 100 to establish the percentage Mo, which when added to the XRF result provided the total Mo content of the sample. The QOL RC samples were taken via a cyclone into plastic sacks at 1m intervals. All samples other than sediments were split using a Jones Riffle Splitter to produce a +/-2kg sample for analysis. This sample was collected directly in pre-numbered calico bags. A matching sample number tag was inserted in each bag which was then tied up. All drill samples were sent to ALS-Chemex’s laboratory in Brisbane for preparation and XRF analysis for Mo, W, Bi, As and Sn. ALS Chemex carried out routine internal checks on the assays from QOL’s Wolfram Camp samples. • Planet Metals Limited (PML) resourcing the new economy for a better tomorrow Page 10 Criteria JORC Code explanation Commentary Core sampling was based on ½ core sampling, with limited selective sampling; as a consequence of the very spotty nature of the wolfram and molybdenum mineralisation the core was cut in such a way as to bisect the mineralisation with ideally equal portions being present on each half of the core. All intercepts of quartz greisen and quartz pipe material were cut as these rock types contain the bulk of the high grade mineralisation, and map appear to be barren until cut. For RC drilling PML used an 87.5:12.5 riffle splitter attached to the base of the cyclone and a 2-3kg sample was collected in a calico bag beneath the 12.5 chute. Drill holes were sampled predominantly over 1m intervals. PML discontinued the practice of handpicking coarse grained molybdenite devised by QOL. All samples were assayed for W, Mo, Bi, As and Sn using the ME-XRF05 method; where samples exceeded the detection limits for that method, they were re-assayed using the ME- XRF15c method, which uses a lithium borate flux to produce a fused glass disc. ALS considered method ME- XRF15c to be more accurate than ME- XRF07; however, it has only been available since early 2009. ALS stated that due to the hardness of common tungsten minerals, in most cases higher concentrations of tungsten may cause bias in the order of 10-15% on the low side by method ME-XRF05. The fusion method ME-XRF15c does not suffer from these mineralogical effects. 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. • QOL Drilling Discrepancies between Mo assay results and visual estimates of molybdenite content from the first 49 RC holes resulted in eighteen RC samples with high visible molybdenite content being manually re-split through a riffle-splitter. The resplit samples were sent to Townsville to undergo the same hand-picking process used with selected intervals of diamond core. Results showed less variation in Mo values than expected, although 16 showed a minor increase in Mo grade. Repeatability of the W grade proved far more erratic with 15 samples showing increased W grade resourcing the new economy for a better tomorrow Page 11 Criteria JORC Code explanation Commentary (including one from 0.095% to 2.92%) whilst 3 showed minor decreases in grade. Blanks and assay standard samples were used, with blanks inserted in sample batches as samples with numbers ending in 00 and 50 and standards inserted as samples ending in 25 and 75. Standards were acquired from CANMET Mining and Mineral Science Laboratories, Ottawa, Canada, and from CDN Resources Laboratories Limited, British Columbia, Canada. Analyses of these samples showed excellent quality control in the laboratory, again indicating all variations are due to the nugget effect in the mineralisation. 95 RC intervals were randomly selected for re-splitting through a riffle splitter. Of the 95 samples 42 (44%) showed an increase in Mo content in the second sample (with 12 showing variation of less than 5%) and 35 (37%) showed an increase in W content in the second sample (with 18 showing variation of less than 5%). A number of pulps (originally assayed at Ultratrace) were re-assayed at ALS in Townsville and an excellent correlation between the two sets of assays was returned. Sample and assay data have been acquired in accordance with acceptable industry standards. • PML Drilling The QAQC results for drilling indicated that the assays for the PML drilling program were satisfactory for resource estima
