ASX ANNOUNCEMENT 24 April 2018
STRONG PROGRESS CONTINUES AT GOLDEN EAGLE UNDERGROUND MINE
HIGHLIGHTS
-
➢ Production stoping commenced on first level (375)
-
➢ Ore development advancing well on second level (355)
-
➢ New upper level established to access additional ore (395)
-
➢ Face sampling at 395 portal returns 13.5m @ 9.11g/t Au
-
➢ Underground drilling well underway, aimed at delineation of Central Shoot
Eastern Goldfields Limited (ASX: EGS) ( Eastern Goldfields or the Company ) is pleased to provide an update on progress at its Golden Eagle Underground Gold Mine, located approximately 2.5 km south of the Davyhurst Mill and 120 km northwest of Kalgoorlie (refer Figure 4).
Ore development has been completed on the first level (375 Level), with a total of 179 metres of advance. In the north drive, ore development was extended past the defined limit of the resource model by an additional 53 metres due to grade extensions of the main lode. Stope production has now commenced and continues to progress.
Ore development on the second level (355 Level) is well established with a total of 130 ‐ metres of advance completed to date. The main ore lode (Quartz Feldspar Lode, or QFL) to the north has returned strong gold grades to date. Development to the south is progressing well and is expected to extend into the “Central Shoot” in the coming weeks.

As announced to the ASX on 28 March 2018 – “Company Update”, an internal review of the mine design resulted in the planning of an additional ore development level (395 ‐ Level) above the 375 Level. Ultimately this re design is expected to increase the mined ounces for the Golden Eagle deposit, although it has resulted in some delay to planned stoping activities on the 375 Level. A new portal has been established in the north wall of the open pit, with ore development underway. Face sampling at the portal location has identified the potential for the mineralised system to be economically bulked together, shifting from 3-5 metre lode widths (hanging wall only) to 10-15 metre widths (combined hanging wall & footwall lodes).
Approximately 20 metres of ore development is now complete which has encountered strong gold mineralisation in the main ore lode horizon (hanging wall). Work continues on defining the bulk tonnage potential which incorporates both the hanging wall and the footwall lode and the internal dilution between the two.
Executive Chairman Michael Fotios said:
“We have a high level of activity within the Golden Eagle Mine and some pleasing trends are emerging. Overall, we are seeing gold grades that are consistent with those previously estimated in the resource model. Geologically, we are seeking to better define the bulking potential within specific parts of the north shoot and are eagerly awaiting the results of underground drilling targeting the Central Shoot.”
A 30 hole, 3,500 metre diamond and underground reverse circulation (RC) drilling program has commenced and is aimed at defining resource extensions associated with the Central Shoot. The Central Shoot has the potential to add significant tonnes and grades to the mine plan. To date, 840 metres of diamond drilling has been completed, with RC drilling currently underway. Assay results are pending.
About Golden Eagle
The Golden Eagle deposit is hosted within a 10-20 metre wide mineralised (quartz, silica, pyrrhotite and pyrite), sub-vertical, siliceous biotite schist. Historically, mining in the Golden Eagle pit has focused on the Central and Northern Shoots. In the Central Shoot, a hanging wall and a footwall lode were mined. In the Northern Shoot, mining focused on the hanging wall lode, although drilling has intersected narrow high-grade mineralisation in the footwall position. Both shoots plunge north at between 20 and 30 degrees.
Within the larger biotite schist unit, a high grade quartz-feldspar lode (QFL) association has developed in the hanging wall position of the Northern shoot and is the target of the current underground mining plan. This same unit hosts the Lights of Israel Deposit (located 3 km north along strike of the same structure) which has produced 4,000,000 tonnes @ 3.1 g/t for 400,000 ounces to date, through both open pit and underground mining.

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. |
• 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.

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) |
| 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). |
• Aberfoyle/Bardoc - RC, RAB and Diamond details unknown however NQ diamond known to be used. RC drilling between 4 and 6 inch diameter with use of face sampling hammer known from 1992 onwards. • Cons Gold \Consex– NQ diamond and HQ (triple) for geotechnical holes.

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 20thsample 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.

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. Gannet standards and blank samples made by Croesus were submitted with split sample submissions. QAQC analysis of repeats was analysed by Croesus Mining NL. for their drilling completed during 2000. • EGL - samples sent to Intertek, SGS and Nagrom laboratories. The samples have been analysed by firing a 50gm portion of the sample. Lower sample weights may be employed for samples with very high sulphide and metal contents. This is the classical fire assay process and will give total separation of gold. An ICPOES finish was used. Commercially prepared standard samples and blanks are inserted in the sample stream at a rate of 1:10. Sizing results (percentage of pulverised sample passing a 75μm mesh) are undertaken on approximately 1 in 40 samples. The accuracy (standards) and precision (repeats) of assaying are acceptable. • Billiton - Laboratory and methods unknown, Standards for RAB and RC inserted however frequency unknown • Fire Assayis considered a total technique,aqua regia is considered apartial technique. |

• EGL geologists have viewed selected diamond holes from certain deposits and verified the location of mineralised intervals. • EGL - Geological and sample data logged directly into field computer at the core yard using Field Marshall. Data is transferred to Perth via email and imported into Geobank SQL database by the database administrator (DBA). Assay files are received in .csv format and loaded directly into the database by the DBA. Hardcopy and/or digital copies of data are kept for reference if necessary. • Holes have not been planned to specifically twin historic intercepts. • No adjustments are made to any assay data. First gold assay is utilised for any reporting. • Data entry, verification and storage protocols for remaining operators is unknown. |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
• RAB and AC holes are/were not routinely collar surveyed or down-hole surveyed due to their limited use in resource estimation. To this end, discussion of RAB and AC drilling is omitted from this section. RC/GC (grade control) and shallow RC holes are/were not routinely down-hole surveyed due to their shallow nature reducing the chance of significant deviation. Barren exploration RC holes not routinely down-hole surveyed or collar surveyed. DD holes routinely collar and down-hole surveyed by most operators or have been re-surveyed by subsequent operators. • The influence of magnetic rocks on the azimuths of magnetic down-hole surveys is minor.

Drill hole collar positions are picked up by mine surveyors using RTK GPS subsequent to drilling. Drill-hole, down-hole surveys are recorded every 30m using a reflex digital down-hole camera. Underground DD holes drilled in 2018 surveyed every 6m using a north seeking gyro tool. • Face data is QAQC validated before importing into the main database (Geobank). The face data is visually inspected once plotted into a drillhole trace form. Survey pickups of development is used to determine coordinates of each face, along with sample locations. These coordinates are then used to generate a pseudo drill trace and sample intervals. |

|---|---|---|
| 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. |
• 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. |
|
| 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 Lights of Israel and Great Ophir historic surface holes were generally vertical. All current drilling is inclined at -70oto -75o on order to obtain oriented core. Azimuths and inclinations were determined to achieve optimum intersection with the mineralised lode. • It is unknown whether the orientation of sampling achieves unbiased sampling, though it is considered unlikely. • Face sampling is conducted as close to perpendicular to the ore body as possible. |
| Sample security |
• The measures taken to ensure sample security. |
• Unknown for most operators. • Cons Gold – RC residues stored onsite. • EGL – All samples, including face samples, are bagged, tied and placed in a secure yard. Once submitted to the laboratories they are stored in cages within a secure fenced compound. Samples are tracked through the laboratory via their LIMS. • Samples are either driven to the laboratory directly by the geologist or field assistant or samples are dropped at the company owned mill (remote location) and picked up by the laboratory’s personnel within the hour. |

• The LOI deposit was discovered sometime prior to 1906 and was worked underground between 1906 and 1913. Open pit mining commenced in January 1988 by Aberfoyle Ltd initially in a JV and later through a wholly owned subsidiary Bardoc Gold Pty Ltd. Mining was conducted in two phases, 1988-990 and 1993-1994. In late 1994 a decline was established to assess the down plunge continuation of the ore below the open pit. A trial mining episode was carried out in 1995, followed by the decision in early 1996 to proceed with an underground operation. In 1996 Consolidated Gold (Consgold) acquired all interests of Bardoc Gold, including the LOI deposit form Aberfoyle. Underground mining continued until February 1999 when Consgold was placed in administration. In January 2001 Croesus purchased the Davyhurst assets from the receiver and commenced mining the Giles deposit in March 2001. A JV was reached with Croesus and Barminco to mine the LOI deposit in June 2002 with production continuing until August 2004. |

| • 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. • To date 3 NE dipping faults have been identified at LOI that dip at approximately -26oto 040oand are consistently identifiable as they have been intruded by felsic porphyries (LOI Footwall Porphyry, Makai Porphyry and the Hangingwall Porphyry). |
| 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. |
• Refer to Appendix 1 for additional information. |
| 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. |
• 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 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 mineralisatio n widths and |
• 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. |
• 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. |

| intercept lengths |
• 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’). _ |
• 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 above diagrams |
| 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 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 bare 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. |
