ASX ANNOUNCEMENT 19 May 2016
Drill results from Golden Eagle delivers near term mining target
Eastern Goldfields Limited (ASX:EGS) ( Eastern Goldfields or the Company ) is pleased to announce that drilling on the Golden Eagle Deposit ( GED ), located near Davyhurst in Western Australia has confirmed the Company’s recently revised geological model and the importance of the Quartz-Feldspar-Lode ( QFL ) association with the location of high gold grades.

The GED has been identified as an additional near term underground mining target. The revised geological model was developed with a focus on defining the high grade hanging-wall mineralisation (see Figure 1 & 2) from the broader 10-20 metre wide mineralised zone that was previously bulk mined in a large open pit.
The first phase of drilling is now complete, with results confirming that mineralisation extends over 100m north of the existing resource boundary and remains open at both depth and in the down plunge direction. These results will now be incorporated into an updated and extended underground Resource model. The exploration potential of this deposit remains high with both the hanging wall and footwall horizons remaining open at depth.
The GED is hosted within the same geological unit as the Lights of Israel Deposit that historically produced 4.7Mt @ 3.0g/t Au and was mined to over 500 vertical metres below the natural surface. The GED displays numerous geological similarities, suggesting the exploration potential for down plunge continuation remains significant.
The Company has previously informed the market that underground mining evaluation work has returned positive results. The Company is now in advanced discussions with a specialist underground mining contractor regarding the commencement of mining in the second half of 2016. All the statutory approvals required to commence mining have been lodged with the regulator and are currently being assessed.

1.1 Section 1 Sampling Techniques and Data
Information for historical (Pre Eastern Goldfields Limited from 1996 and 2000) drilling, sampling, mining and milling of the Golden Eagle deposit 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.

| amphibolites are the host rocks to the Golden Eagle deposit. The ore | ||||
| zone is described as a biotite altered shear zone with discontinuous | ||||
| rodded quartz lenses that plunge 20oto 30oto the NNW. The | ||||
| footwall of the shear zone is basalt and the hanging wall is dolerite. | ||||
| In the hangingwall of the shear zone is a generally narrow (<2m) | ||||
| zone of plagioclase+quartz+calcite+biotite+ | ||||
| actinolite+pyrite+pyrrhotite alteration, locally known as Quartz | ||||
| feldspar Lode (QFL). Veining in the Golden Eagle Lode consists of two | ||||
| main types: early, narrow, deformed quartz+actinolite+ | ||||
| feldspar+diopside+pyrrhotite veins (including the QFL), and later, | ||||
| boudinaged, massive quartz veins. An ENE-striking buck quartz vein | ||||
| cuts and displaces the Golden Eagle lode by as much as 10m in a | ||||
| dextral manner in the central part of the pit. Similar structures have | ||||
| been mapped on surface and can be expected to dislocate the | ||||
| northern strike extents of the deposit. | ||||
| | Mineralisation is associated with the biotite altered shear zone and | |||
| can be > 10m thick. The shear zone strikes NNW and is steeply | ||||
| dipping to the west. Higher grades are dominantly associated with | ||||
| the QFL if present. Minor, discontinuous shears are present in the | ||||
| foot wall and hanging wall to the main shear and are mineralised. | ||||
| Associated with the gold mineralisation are | ||||
| plagioclase+quartz+calcite+biotite+ actinolite+pyrite+pyrrhotite | ||||
| alteration minerals. A study of grade control drilling at the deposit | ||||
| has identified a shallow 20oto 30oplunge to the NNW, similar to the | ||||
