Maiden Sand King Open Pit Reserve

Highlights

  • JORC 2012 Reserve at Sand King of 820,000t @ 2.5g/t Au for 65,000 ounces

  • Combined Missouri & Sand King Reserve now totals 2,025,000 tonnes at 2.3g/t Au for 150,000 ounces

  • Siberia Project mine ready

  • Company fully funded to production via access to Investec debt facilities

Eastern Goldfields Limited (ASX: EGS) ( Eastern Goldfields or the Company ) is pleased to announce a maiden open pit Reserve for the Sand King Deposit of 820,000t @ 2.5g/t Au for 65,000 ounces. The Sand King Deposit forms part of the Siberia Project, located approximately 37 kilometres from the Company’s Davyhurst Mill (Figure 1).

This now completes the current phase of resources and reserve generation work at the Siberia Project and establishes a combined open pit mining Reserve for the Missouri and Sand King deposits of 2,025,000t @ 2.3g/t Au for 150,000 ounces . This represents a 30% gold ounce conversion from the combined resource of 4,884,000 @ 3.2g/t Au for 498,000 ounces with the majority of the non‐converted ounces sitting below the optimised open pits. Mine evaluation work investigating the underground mining potential beneath these two deposits continues. Importantly, all the necessary statutory approvals are now in place to commence mining at Siberia.

Executive Chairman Michael Fotios said:

“The combined Sand King and Missouri Reserve will underpin the baseload feed requirements for the Davyhurst plant whilst establishing an early robust cash flow for the early years of the project. We intend to combine supplementary oxide open pit ores and higher grade underground ore feed over the baseload as the Project develops. With the completion of Reserve generation works delivering such strong gold ounce conversion, we now look forward to the commencement of mining at Siberia in the coming weeks.”

The key characteristics for the proposed Sand King Open Pit as tabled below:

Key Characteristics Units
Waste Tonnes Moved 3.8 M bcm
Ore Tonnes Processed 820 K tonnes
Stripping Ratio 12:1 O:W
Mine Life 23.0 Months
Average Head Grade 2.5 (g/t)
Total Metal Production 65.0 Oz ('000)
Metallurgical Recovery 93.0 %
Total recovered ounces 60.5 Oz ('000)
C1 Cash Costs / oz* 1,089 A$

*Note – C1 Cash Cost / oz presented have been calculated utilising the combined total cost of both the Missouri and Sand King open pits over the operating life of the Siberia project.

Approximately 10,000 ounces of inferred resource has been captured within the designed pit and which has not been included in the Reserve estimation. The Company intends to further evaluate this material in the operational phase by extending the planned grade control programs to ensure sufficient coverage is achieved over these inferred areas.

Sand King – Ore Reserve Calculation

Measured and Indicated Resources have been converted to Proven and Probable Ore Reserves respectively, subject to mine design physicals and an economic evaluation. Any Inferred material contained within the mine plan has been treated as waste. The Ore Reserves have been defined at delivery to the processing plant ROM pad.

The Ore Reserve estimate is based on financials and modifying factors determined as part of a recent mining study undertaken on the operation.

Ore from Sand King will be extracted using surface mining techniques. Surface mining contractors will provide mining services using a conventional mechanised fleet consisting of 120 t sized excavators loading 90 t trucks for load and haul, with diesel powered mobile drills drilling blastholes and ANFO emulsion explosives delivered to these holes by mobile explosives mixing units.

Independent expert geotechnical consultants provided geotechnical recommendations for Sand King, to a PFS level of detail.

Mining factors for open pits have been determined based on a selective mining unit (SMU) analysis. SMU parcels are created adhering to a minimum mining width and a specified cut‐off grade of 0.82g/t gold. This cut‐off grade was determined using a lower input gold price, giving a more conservative approach.

2

Metallurgical recoveries were based on historical production data from the Davyhurst processing plant.

Revenue was based on a gold price assumption of AU$1,550/oz. A Western Australian government royalty of 2.5% has been applied in the financial model.

All material was subjected to an economic evaluation. A detailed financial model deemed to PFS level of accuracy was generated for the evaluation.

All required environmental and regulatory approvals have been granted for the mining operation at the Siberia Project.

Section 1 Sampling Techniques and Data

Information for historical (Pre Eastern Goldfields Limited) 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.

Sand King is an orogenic lode style deposit hosted by mafic rocks, predominantly basalt

Gold mineralisation at Sand King takes the form of stacked quartz‐biotite‐feldspar‐sulphide shear lodes within the basalt. Widths vary
from sub 1m to ~ 6m true width. Mineralised structures are NE‐SW striking in the south and normally steeply dipping to the north while in
the north‐eastern end of the deposit mineralisation is interpreted to dip shallower to the north ( ~60 degrees)

Ordinary Kriging (OK) was used to estimate gold grades into a 3‐dimensional block model. Estimation parameters derived from modelled
semi‐variograms. Micromine software was used for the estimation.

A high grade cut of between 10 and 30g/t was applied to 1m composite data based on analysis of individual domains.

The parent block dimensions used were 10m NS by 10m EW by 5m vertical with sub‐cells of 1m by 1m by 0.5m. Drill hole spacing is
approximately 20m between section and 20m along section. A parent block size of 10m x 10m x 5m was selected (approx. 50% of data
spacing)

An orientated ellipsoid search was used to select data and was based on parameters derived from the variography.

Estimation completed in 4 runs each with less restrictive search, and minimum sample parameters. The initial interpolation pass was used
with a maximum range of 70m and minimum number of samples of 20. Range increased progressively and number of samples required
reduced for each subsequent run.

No estimation of deleterious elements was carried out. Only Au was interpolated into the block model.

Environmental
factors or

Assumptions made regarding possible waste

always necessary as part of the process of
determining reasonable prospects for eventual
economic extraction to consider the potential
environmental impacts of the mining and
processing operation. While at this stage the
determination of potential environmental
impacts, particularly for a greenfields project,
may not always be well advanced, the status of
early consideration of these potential
environmental impacts should be reported.
Where these aspects have not been considered
this should be reported with an explanation of
the environmental assumptions made.

The previous mining operations included the development of waste dumps at the site. These dumps will be expanded to accommodate
additional waste disposal.

The area is not located in an environmentally sensitive area so there is no reason to believe that environmental approvals would restrict
development of the project.

The bulk density for bulk material must have
been measured by methods that adequately
account for void spaces (vugs, porosity, etc),
moisture and differences between rock and
alteration zones within the deposit.

Discuss assumptions for bulk density estimates
used in the evaluation process of the different
materials.

Bulk density determinations were derived from historic measurements.

Bulk density values used in the resource were 1.8t/m3, 2.4t/m3 and 2.85t/m3 for oxide, transitional and fresh mineralisation respectively.
Waste basalt bulk density was 3.0t/m3

These bulk density estimates are similar to values determined for comparable basalt hosted gold deposits

Competent Person’s view of the deposit.

Mineral Resources were classified in accordance with the Australasian Code for the Reporting of Exploration Results, Mineral Resources
and Ore Reserves (JORC, 2012). The Mineral Resource was classified as Indicated and Inferred Mineral Resource on the basis of data
quality, sample spacing, and lode continuity.

The Indicated portion of the Mineral Resource was defined where:
o
Good data support exists with drill hole spacing averaging 20m x 20m
o
Low kriging variance (<0.3) and average distance of informing points less than 20m.

The remaining portions of the deposit were classified as Inferred Mineral Resource where:
o
Data support is poorer with drilling typically greater than 20m x 20m
o
Estimation quality is lower defined by a slope of regression typically between 0.3 and 0.65

Inferred resources are typically at the periphery of mineralised domains and at depth where confidence is generally lower

The definition of mineralised zones is based on sound geological understanding of the controls on mineralisation. This has produced a
robust model of mineralised domains. This model differs slightly from previous models where only steep lodes were modelled. The
northern end of the deposits has moderately north dipping lodes modelled. d resources are typically at the periphery of mineralised
domains and at depth where confidence is generally

The Mineral Resource estimate appropriately reflects the view of the Competent Person.

Discussion of
relative
accuracy/
confidence

Where appropriate a statement of the relative
accuracy and confidence level in the Mineral
Resource estimate using an approach or
procedure deemed appropriate by the
Competent Person. For example, the application
of statistical or geostatistical procedures to
quantify the relative accuracy of the resource
within stated confidence limits, or, if such an
approach is not deemed appropriate, a
qualitative discussion of the factors that could
affect the relative accuracy and confidence of
the estimate.

The statement should specify whether it relates
to global or local estimates, and, if local, state
the relevant tonnages, which should be relevant
to technical and economic evaluation.
Documentation should include assumptions
made and the procedures used.

These statements of relative accuracy and
confidence of the estimate should be compared
withproduction data, where available.

The Sand King Mineral Resource estimate is considered to be reported with a reasonable degree of confidence. The data quality is good
and the drill holes from recent drilling have detailed logs produced by qualified geologists. Historic logging has been reviewed.

The Mineral Resource statement relates to global estimates of tonnes and grade. Confidence in the estimate allows reasonable
quantification of global metal content. However at a local scale there are risks associated with the estimation, largely due to the deposit
consisting of numerous stacked lodes in multiple orientations. The interpretation is considered globally robust but at a local scale
variations to ore geometry could be expected.

The deposit is not currently being mined.

Historical production records are available for the deposit when previously mined.
