As reported on 4[th] April 2017, fieldwork by the Company included extensive examination of old workings at Amamoor and Eel Creek. Bulk samples collected from the Amamoor (MVAM) and Eel Creek (MVEC) deposits were submitted for chemical and mineralogical analysis and metallurgical characterisation to a Perth laboratory.
The samples were crushed to 20mm for analysis and a sub-sample of each crushed to 1mm for gravity profiling by heavy liquid separation (HLS) at densities of 2.8 and 3.3. The SG 3.3 sinks – or concentrates – were then subjected to mineralogical analysis by X-ray diffraction (XRD) (refer table below).

Most of these products appear to be suitable for ferroalloy smelting. MVEC01 is effectively DSO with an in-situ grade above 40% Mn. Concentrate phosphorous contents are all acceptably low, being below the 0.2% limit generally imposed. The iron contents are low , but this can be compensated for in ferroalloy smelters by adding iron ore to the furnace feed mix or by blending with high iron ores.

Two of the Amamoor samples, MVAM01 and MVAM03, did not respond to beneficiation and the mineralogy revealed high amorphous content related to weathering. It is expected that samples to be produced from diamond drilling exploration will better define the bulk character of fresh mineralisation below these sample sites (Figure 2).

Commenting on these highly encouraging results, Mr Carl Popal, Executive Chairman of Eclipse Metals, said:
“ Previously within only the two small areas of the Mary Valley project, technical evaluation indicated the potential for at least 167,000t of high grade manganese mineralisation. Recent geological and geophysical surveys have further provided exciting results at both Amamoor and Eel Creek. These results indicate that substantial gravity features probably represent areas of significant manganese mineralisation below shallow overburden which increases the overall size potential. Positive metallurgical results affirm that this manganese mineralisation is amenable to beneficiation with acceptable low phosphorous in concentrates. Overall the results to date have further increased potential for (DSO) manganese production in Mary Valley.
“We look forward to updating the market on further progress with the development of our projects and results from planned drilling for confirmation of manganese mineralisation at depth”
For and of behalf of the board.

Criteria |
JORC Code explanation |
Commentary | |
|---|---|---|---|
| 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. |
• Chip sampling from outcrop and old mining exposure. Over 100kg combined weight of samples collected. |

• Not applicable as no drilling was undertaken |
|
| Drill sample recovery |

• Not applicable as no drilling was undertaken. |
|
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | **JORC Code explanation ** | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
• EPM17672 & EPM17938 are held beneficially for Eclipse Metals Limited in its subsidiary Walla Mines Pty Ltd. Eclipse holds 87% of the current securities within Walla Mines Pty Ltd. • EPM 25698 held 100% by Eclipse Metals Ltd |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
• Manganese ore has been mined intermittently from deposit in the Mary Valley since 1920’s, with the bulk of the output occurring from 1957-1960. |
| Geology | • Deposit type, geological setting and style of mineralisation. |
• In the Mary Valley Manganese Project, deposits were formed by geochemical separation of manganese from iron in a submarine exhalative system. Deposition of the manganese oxide has apparently been controlled by faulting and fracturing of the incompetent cherty and jasperoidal bed, with the fractures providing the fluid channel-way and replacement of the host rock by manganese oxides occurring progressively awayfrom those fractures. |
| 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: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation above sea level inmetres) of the drill hole collar o dip and azimuth of the holeo down hole length and interception deptho hole 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. |
• No applicable as no drilling was undertaken |
| 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. _ |
• Not applicable as no data averaging has been used |

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Relationship between mineralisatio n 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’). |
• Not applicable as no drilling undertaken. |
| 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 Map in release |
| 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. _ |
• Not applicable |
| 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. |
• Geological background provided in previous reports. |
| 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. |
• Diamond drilling programme being planned. |
