Indicative Project Development Plan – by Deposit + est.

capex

The production targets stated are based on the economic evaluation of Inferred and Indicated JORC 2004 compliant Resources. All evaluation work has utilised industry standard costs and production rates.

There is an inherent lower level of geological confidence with the Inferred Resources and there is no certainty that further exploration will result in the determination of Indicated Mineral Resources.

Lights Of Israel (LOI) Complex – 3D View

Note: The potential quantity and grade of the Exploration Targets are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource, and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Note : Refer to ASX announcements dated 28 January 2016, 10 August 2016 and 9 February 2017 for further information.

12

LOI Complex Exploration Targets - Additional Information

The Exploration Targets are based upon a comprehensive geological and mineralisation review conducted by Eastern Goldfields Limited. This modelling utilised a combination of exploration drilling data, underground sampling along with detailed geologic observations. A high proportion of the LOI deposit was drilled with diamond core and as such there has been significant data available to compile geologic models and justify the projection of mineralisation down plunge.

Historical survey, geology and assay records reviewed, validated and were utilised to create a 3-dimensional geological and mineralisation model. RC drill diameter was 5 ½ inch and diamond core size was NQ. RC drill sample were collected at 1 m intervals and diamond core was cut to geological intervals. Assay methods of drill hole samples was by aqua regia or fire assay using accredited laboratories.

The grades of these exploration targets has been assigned by detailed assessment of previous production from the Lights Of Israel and Great Ophir Deposits along with detailed statistical modelling ( ID2 and Ordinary Kriging) of sample grades from within the mineralised systems. In areas where there is little or no existing data the grade has been derived from the geological investigations into continuity of existing mineralisation and geology (projecting down plunge) and are conceptual in nature with confirmatory RC and DD drilling required to validate these targets. Drilling began in late 2016, with the first reconnaissance holes drilled, Samples were submitted to accredited laboratories for gold assay (fire assay) with a full suite of QAQC samples (blanks, standards and field duplicates).

Planned Exploration work:

In the short term (2017) Eastern Goldfields Limited plans to drill additional RC and diamond holes to evaluate the geology, grade and width of the target. Drilling will target areas below current mining depths. Samples will be submitted to accredited laboratories for gold assay with a full suite of QAQC samples (blanks, standards and field duplicates). If this drill program is deemed successful a geological and resource model will be produced. The resource model will be classified as inferred/indicated as deemed appropriate.

Callion Exploration Target – Additional Information

Basis for the Callion Exploration Target:

The Exploration Targets were calculated using historic data that was collated by Eastern Goldfields Limited. The data consisted principally of channel sample assays and ore thicknesses and RC and diamond drill intersections. Lubbock compiled these data into mine blocks with associated grades and tonnages. Historical survey, geology and assay records were used to create a 3- dimensional model of the underground workings. The channel samples were collected across the width of the drive and/or stope face, generally perpendicular to the strike of the structure that controls mineralisation. Sample and assay methods of underground channel samples is unknown. RC drill sample were collected at 1m intervals and diamond core was cut to geological intervals. Assay methods of drillhole samples was by aqua regia or fire assay using accredited laboratories. In total, there are 1608 stope samples, 947 face samples and 13 drill hole samples used within the area of calculated Exploration Target.

Techniques for Calculating the Grade and Tonnage Ranges for the Callion Exploration Target:

Hard copy survey and geology plans and long sections were digitised and registered in 3-dimensional space. A 3-dimensional model of the ore zones was constructed from the registered plans and drillhole data. Gold assay grades and widths were digitised from the plans. Due to the narrow and variable width of the orebody the estimation was based on an accumulation method. The accumulation varible (GramMetres = Width*Au Grade) and the Width were estimated (Ordinary Kriging) into a block model. The grade was back-calculated by dividing the estimated GramMetres by the estimated Width. A specific gravity of 2.7 t/m3 for fresh rock was applied based on 22 core samples.

Planned Exploration work:

Eastern Goldfields Limited started a comprehensive RC and diamond drilling program in 2016 to evaluate the geology, grade and width of the target. Drilling has successfully intercepted mineralisation in remnant pillars and areas below current mining depths. Samples were be submitted to accredited laboratories for gold assay with a full suite of QAQC samples (blanks, standards and field duplicates). Further drilling has been proposed and will continue in 2017, which at its completion a detailed geological and resource model will be produced. The resource model will be classified as inferred/indicated as deemed appropriate.
