ASX ANNOUNCEMENT 8 August 2017
DAVYHURST EXPLORATION AND OPERATIONS UPDATE
HIGHLIGHTS
-
13 drill holes completed at the Riverina gold deposit, within which visible gold has been intersected
-
Assay results pending for both Riverina and Callion
-
Processing plant achieving prolonged uninterrupted production periods, nearing a stable state
Eastern Goldfields Limited (ASX: EGS) ( Eastern Goldfields or the Company ) is pleased to announce an exploration and operations update for the Davyhurst plant and the Riverina and Callion Deposits located within the Davyhurst Mining Hub, approximately 120 kilometres North West of Kalgoorlie.
Diamond drilling continues with 13 drill holes recently completed for 1,680 metres (HQ3/NQ2) over a 530 metre strike length of the Riverina gold deposit. Within the latest drill holes a one metre true width fresh-rock quartz vein has been intersected with visible gold (RVDD16018 from 70 metres downhole or 62m vertical from surface). This drilling is currently evaluating potential open pit mining targets.
This is the first time that visible gold has been identified in drill core at Riverina by Eastern Goldfields. This visible gold is associated with the occurrence of blebby sulphide minerals (>5%) and bioite chlorite alteration. Its presence may indicate that the quartz lodes in the deposit contain a considerable proportion of coarse gold. Additional analysis (screen fire) of coarse gold interval are a standard part of EGS sampling protocols.

The drill core samples are currently being processed and assembled on site and will be dispatched for assaying when ready. There have been a total of 35 holes for 3,830 metres completed of which 16 holes are in the assay laboratory with approximately 1,630 samples due to be received shortly. The remainder of the samples await dispatch from site.
In addition, at the Callion Deposit there are currently a total of 12 holes (1,096 metres) pending results of which 9 holes (600 sample) are in the assay laboratory and are due to be received shortly.
Executive Chairman Michael Fotios said:
“We are very pleased with the continued drilling success at Riverina. We remain highly encouraged by the results flowing from this deposit. We are also very proud of our operational team who have come together seamlessly to achieve numerous operational improvements seen within the processing plant over the last week. This all bodes well for the future of the Davyhurst Project.
Processing Plant Update
Commissioning works continue with the plant now approaching a stable state. From this point, the operation team expects further stabilisation of the plant before commencing the ramp-up of the through-put rate above the current level of 80t/hr. In the last week, the following operational steps have been achieved:
-
Plant now achieving prolonged uninterrupted production periods at an effective operational rate of 80t/hr;
-
Gold-in-circuit ( GIC ) inventory increasing;
-
Davyhurst team successfully commissioned Anglo American Research Laboratory ( AARL ) elution circuit. The first carbon strip has been completed with gold successfully recovered from the circuit. This has resulted in the first carbon in pulp ( CIP ) and gravity gold pour;
-
Davyhurst team working with Process Logic Control ( PLC ) programmers to optimise the plant functionality, which has resulted in a positive increase in the crushing circuit efficiency that has in turn lead to sustained mill feed rates; and
-
Entire leach circuit now on line and functioning to design specification.
Corporate Update
We refer to recent media speculation regarding protests in Kalgoorlie at Diggers & Dealers. The Company has been in constant discussion with these contractors and confirms that the payment of these contractors has occurred or will occur shortly. The Company continues to interact with its contractors in the normal course of commissioning.

JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE
Section 1 Sampling Techniques and Data
Information for historical (Pre Eastern Goldfields 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, Eastern Goldfields Limited has undertaken extensive infill and confirmation drilling which confirm historical drill results. Sections 1 and 2 describe the work undertaken by Eastern Goldfields Limited and only refer to historical information where appropriate and/or available.

| 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. |

• Croesus Mining N.L; Auger samples were taken from an average depth of 1.5m to 2m. RAB and Aircore samples were collected in buckets below a free standing cyclone and laid out at 1m intervals in rows of tens adjacent to the drill collar. Composite analytical samples (~3.5kg) were initially collected over 5m intervals for each hole and a 1m bottom of hole analytical sample. Analytical composite samples were formed by taking a representative scoop through each 1m drill sample. RC drill samples were collected in large plastic retention bags below a freestanding cyclone at 1m intervals, with analytical samples initially formed by composite sampling over 5m intervals. Where samples were dry, analytical composites were formed by spear sampling, using a 50mm diameter plastic pipe pushed through the drill cuttings in the sample retention bag to the base of the bag. The pipe is removed carefully with the contents of the pipe containing a representation of the retained metre. Wet RC drill samples where thoroughly mixed in the sample retention bag and ‘scoop’ sampled to form a 5m composite sample. HQ diamond core was cut into halves and sampled on geological boundaries, to a minimum of 20cm samples or on a metre basis on site. The diamond core was cut using a diamond saw, with half core being submitted to the laboratory for analysis and the other stored. Field samples were taken for RAB, RC and diamond core samples at a rate of 1 in 20. Composite analytical samples returning values greater than 0.1 g/t Au were re-sampled at 1m intervals. • Monarch Gold Mining Company Ltd; Drill hole samples were collected at 4m and 3m composite intervals. All samples at ALS Kalgoorlie were sorted, dried, split via a riffle splitter using the standard splitting procedure laboratory Method Code SPL-21, pulverised in a ring mill using a standard low chrome steel ring set to >85% passing 75 micron. If sample was >3 kg it was split prior to pulverising and the remainder retained or discarded. A 250g representative split sample was taken, the remaining residue sample stored and a 50gm sample charge was taken for analysis. All samples at Ultra Trace Pty Ltd were sorted, dried, a 2.5 – 3kg sample was pulverized using a vibrating disc, was split into a 200-300g subsample and the residue sample stored. A 40grm charge was taken for analysis. Composite samples returning anomalous values were sampled at 1m intervals using a scoop. For both RC and RAB drilling a duplicate sample was collected at every 25th sample, and a standard sample was submitted every 20th sample. • Pancontinental Mining Ltd; RC samples were collected in plastic bags directly from the cyclone at 1m intervals, split twice through a sample splitter before splitting off a 2kg sample for analysis. Samples were crushed to 1mm, 1kg split taken and pulverised to 90% minus 20 mesh from which a 50gm aliquot was taken. Field samples were taken at a rate of 1 in 10 and results show a good correlation with the original values. Samples sent to SGS were dried, jaw and roll crushed, split and pulverised in a chromium steel mill. • Consolidated Gold N.L/DPPL; Auger samples were collected at a nominal depth of 1.5m or blade refusal. Approximately 200gm of material was placed into pre-numbered paper geochemical bags. Sample numbers were entered into a datalogger linked to the GPS unit to ensure accuracy. RAB samples were collected a 1m intervals and used to create a 4m composite sample. Samples were oven dried, pulverised in a single stage grinding bowl until about 90% of the material passed 75 micron. A 50gm split sample was taken for analysis. Composite samples returning values greater than 0.19 Au g/t were sampled at 1m intervals. • Riverina Resources Pty Ltd; Auger soil samples were collected from a depth of 1.8m or blade refusal. RAB and RC 4m composites were taken using a sample spear. Samples were dried, crushed, split, pulverised and a 50gm charge taken. Composite samples returning anomalous gold values were sampled at 1m intervals using a sample spear. • Barra Resources Ltd; Every metre of the drilling was collected through a cyclone into a largegreenplastic bagand lined upin rows near the hole in rows of 20.

| each hole was sampled. Each hole was initially sampled by 4m composites using a spear or scoop. Once each hole was logged, intervals considered to be geologically significant were re-sampled at 1m intervals. 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. Samples greater than 2.5kg were riffle split to <2.5kg using a Jones riffle splitter. The entire sample was then pulverised in a Labtechnics LM5 to better than 85% passing 75 microns. A 50gm pulp was taken for assaying in appropriately numbered satchels. Composite samples that returned gold assays greater than 0.1 g/t Au and that had not been previously sampled at 1m intervals, were re- sampled at 1m intervals. In addition, any highly anomalous 1m samples were also sampled again to confirm their assay results. • Carpentaria Exploration Company Pty Ltd; Samples were collected over 1m intervals. 2m and 4m composite samples were collected using a sample spear. About 2kg samples were despatched for analysis. Samples were dried, crushed, split, pulverised and a charge taken for analysis_._ • Malanti Pty Ltd; 1m samples were collected in plastic bags via a cyclone and passed through a triple splitter giving a 12.5% split of about 2kg which was placed in a calico bag and marked with the drill hole number and interval sampled. The 87.5% was returned to the similarly numbered large plastic bag and laid in rows on site. 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. Samples were dried, crushed, split, pulverised and a 50gm charge taken. RC Samples with anomalous composite assays were split and submitted for analysis. • Riverina Gold Mines NL; Vacuum hole samples were collected every metre and split. RAB samples were taken every metre through a cyclone and riffle split to a quarter and composited to 4m intervals.

RC samples were also sent to Ultra Trace Pty Ltd, Canning Vale Western Australia for gold analysis by lead collection fire assay. Samples were also analysed for palladium and platinum. The Quality control at ALS involved 84 pot fire assay system. The number and position of quality control blanks, laboratory standards and repeats were determined by the batch size. Three repeat samples were generally at position 10, 30, 50 of a batch and the control blanks (one blank) at the start of a batch of 84 samples. The laboratory standards were inserted randomly and usually two certified internal standards were analysed with a batch, but it was at the discretion of the ‘run builder’ as to how many standards to add to the batch and where to place them in the run. QAQC at Ultra Trace Pty Ltd was undertaken for every 27th sample. At random, two repeat samples were chosen, one laboratory standard was inserted and one check sample was taken. The check sample was chosen if the first pass of fire assay shows anomalous value. • Pancontinental Mining Ltd; Samples were sent to Genalysis Laboratory Services Pty Ltd in Perth to be analysed for gold with a detection limit of 0.01 ppm. They were also analysed for gold at SGS laboratory using aqua regia with AAS finish. A number of samples with an assay greater than 0.2 ppm were re-assayed by fire assay. Laboratory standards indicated reasonable accuracy. |

|
| Geology | • Deposit type, geological setting and style of mineralisation. |
• The geology of the Riverina area consists of a sequence of meta-basalts with minor meta- sediments and meta-ultramafics that have a northerly strike and sub-vertical to steep east dip. The area has been affected by upper greenschist to lower amphibolite grade metamorphism with many minerals exhibiting strong preferred orientations. All rock units are foliated with shear zones common. The most intense shear zones have been locally referred to as mylonite zones. Contemporaneous strike faults and late stage faults have dislocated these mylonite zones. • Intense mineralisation and alteration at the Riverina underground mine is confined to the mylonite zones and strike fault systems. Gold mineralisation is intimately associated with quartz veining and sulphides within a broader mylonite zone that also contains non-mineralised parallel quartz veins. Elsewhere mineralisation is found in favourable host rocks where intersected by N-S trending strike faults. Favourable hosts include meta sediments, mafics and mafic/ultramafic contacts |

| Relationshi p between mineralisat ion 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 Mine is approx. N-S and sub vertical. Drilling is oriented perpendicular the strike of the mineralisation. |
| 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. |
• The location of drill hole intersections is shown on the plans and 3D diagrams and are coloured according to grade to provide context for the highlighted intercepts |
