ADMIRAL BAY ZINC-LEAD PROJECT (100% MCT)
Commencement of Pre-Feasibility Study (PFS)
The initial focus of the Pre-Feasibility Study (PFS) on the Admiral Bay Zinc Project has been the refinement of the preferred PFS pathway including the design and budgeting of drilling options in readiness for the field season.
SRK Consulting has been appointed to review the high grade MRE located in M04/249 where the majority of drilling is concentrated . The high-grade MRE of 20Mt at 10% ZnEq (see ASX:MCT 10/2/2015) includes 4.9Mt at 12.5% ZnEq at 11% ZnEq cut-off, and is limited to 2.1km within the 18km global Inferred MRE (Figure 3).
Significant high-grade intersections >10% ZnEq occur in most of the holes that have tested the central axis of the antiform. In the higher-grade zone, seven holes have drilled mineralised zones of >10m in the axial zone and of these three have intersected zones >10% ZnEq and four have intersected mineralisation from 8-10% ZnEq.
The existence of intersections such as 20m at 14.5% ZnEq (including 6m at 24.3% ZnEq) in ABRD001, and 19m at 8.3% ZnEq and 14m at 17.7% ZnEq in SS02 indicates that high-grade zones are present in the axial zone of the deposit and it is considered likely that multiple high-grade zones will be intersected by further drilling.
This high-grade zone is the most logical area for the commencement of mining to accelerate payback on preproduction capital and it is a priority to convert a relevant portion of this zone to the indicated category. The design and budgeting of drilling options hence has focussed on this portion of the deposit.
During the quarter a Memorandum of Understanding ( “MOU” ) with CNFC Equipment Co.,LTD, ( “CNFC” ), a holding subsidiary company of the leading zinc project development group, China Nonferrous Metal Industry’s Foreign Engineering and Construction Co., Ltd ( “NFC” ) , to advance Admiral Bay, was signed. The MOU is the first step in a potential partnership regarding the feasibility, development, financing and construction of Admiral Bay.
The MOU followed several meetings held by Metalicity and NFC in Beijing as part of the Joint Venture process being run by the Company. Alternative discussions with other parties including global resources houses and financiers regarding an investment in Metalicity and/or Admiral Bay are also at an advanced stage.

COBALT PROJECTS (100% MCT)
Kyarra Nickel-Cobalt Project
Following up the identification of historic high grade, widespread cobalt anomalies at the Kyarra Cobalt Project field work commenced. The initial field visit to the Kyarra West target area in mid-March to verify historic cobalt anomalism identified by previous workers (see MCT ASX announcement 15/3/2017) was interrupted by rain. However, several rock chip samples were collected for which assay results confirm surface base metal anomalism, with results up to 535 ppm Ni, 248 ppm Co, and 1830 ppm Zn, (Table 1, Figure 6). Further field work is planned once ground conditions improve.
The company has commissioned a targeting study of the Yerrida Basin by Dr Dennis Gee, previously Deputy Director of the Geological Survey of Western Australia, and Regional Manager, Exploration with Mount Isa Mines Ltd. Dr Gee has published several technical papers on the stratigraphy and structure of the Yerrida Basin based on extensive field experience in the area, having supervised the completion of 1:250 000 scale regional mapping of Western Australia. The study is expected to be completed within the June Quarter.

Rocky Gully Nickel-Cobalt Project
During the period an Independent Review was undertaken on the Rocky Gully Project by Martin Bennett, which highlighted the Nickel-Cobalt sulphide potential of the M20 and M19 prospects. Previous near surface drilling by the Company (see ASX:MCT 04/11/14) consisted of 5 RC holes for a total of 362m and was aimed at verifying nickel copper and cobalt mineralisation. Drilling confirmed the presence of sulphides and extended the known mineralisation at shallow depths of <100m.
All holes intersected nickel cobalt minerlaisation in the weathering profile, including intercepts of 1m at 2.05% Nickel and 0.05% Cobalt. Significantly, at the M20 target, hole M20RC001 intersected around 30m of tertiary cover and underneath this, weathered ultramafic was noted, while secondary nickel minerals were observed towards the base of the weathered zone in this hole.
Follow up exploration will focus on the M20 Nickel-Cobalt target, as the coincidence of laterite soil anomalies, circular magnetic anomalies, EM conductors and significant nickel cobalt intersections in drilling make this a high priority nickel cobalt target. An IP survey and or Downhole EM survey is planned followed by deeper drilling.

LITHIUM PROJECTS (100% MCT)
Pilbara Lithium Projects
Following on from the intersection of significant lithium mineralisation in first pass drilling at the Stannum Lithium Project, a recent Heritage survey covering the areas planned for phase 2 and additional drilling has been completed with no major impediments to the planned program identified. The Company anticipates drilling will commence in the June Quarter. Drilling will aim to follow up previous lithium anomalism identified in drilling (Figure 7). X-Ray Diffraction analysis carried out by ALS Laboratories, Perth on 3 samples with anomalous lithium revealed the presence of eucryptite (an alteration phase of spodumene) in all 3 samples; and a possible trace of petalite.
At Lynas Find North, recent mapping identified significant numbers of pegmatites, often outcropping as a series of stacked, sill-like bodies (see MCT ASX announcement 15/3/2017). Assay results from the rock chip samples collected have been received and demonstrate the pegmatites are significantly fractionated, with anomalous potassiumrubidium (K/Rb) and potassium-cesium (K/Cs) ratios, and lithium values. Key results are presented in Table 2, all results in Appendix 1; refer Figure 8. These fractionation indices (K/Rb and K/Cs) are suggestive of the presence of rare metal mineralization. Rb and Cs are known to concentrate in K bearing minerals such as K feldspar and micas. The company considers that values of K/Rb < 50 and with Cs > 12 ppm (4 times background) or K/Cs < 1500 are of significance. Low ratios for K/Rb and K/Cs are well known to be associated with lithium and tantalum mineralized pegmatites, indicated from several academic studies (e.g. Selway et al., 2005).

Lake Cowan Lithium Project
At Lake Cowan the second round auger program has returned additional elevated levels of lithium (Li), cesium (Cs) and rubidium (Rb) (Figure 9). These results provide further encouragement for the Company to progress a targeted reverse-circulation (RC) drilling program to confirm the presence of buried rare metal pegmatites in this location. The coincidence of these three elements is considered a good indicator of a nearby underlying fractionated pegmatite that could host lithium mineralization. The Program of Work proposal (PoW) has been approved and heritage survey imminent to allow RC drilling to potentially occur in the June Quarter.
The auger program consisted of 50m spaced auger holes on 200m spaced lines over the originally defined anomaly to infill and more closely define a previously identified target, the ‘Salt Creek Prospect’, where rare metal pegmatites have been interpreted to extend into the Company’s tenement area under a shallow veneer of cover material.

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. |

| Lynas Find • Previous exploration work within the tenement area has consisted of regional mapping, soil and bulk sampling and drilling by various parties primarily exploring for gold and tantalite. Limited small scale mining for tin and tantalum has occurred previously. • Limited sampling has been undertaken in the areas covered by this work primarily focusing on the discovery of tantalum and tin mineralisation. Stannum • Metalicityhas undertaken mappingand surface samplingas well as RC drilling. |

| Geology • Deposit type, geological setting and style of mineralisation. |
Lake Cowan • The Company is exploring for rare metal pegmatites in the project area. The geology of the area is dominated by Archaean Mt Belches Formation metasedimentary units, intruded by granites and pegmatites which are known to host rare metal mineralisation including tin, tantalum and lithium. Previous exploration in the Mount Belches-Bald Hill pegmatite belt focused on Tantalum and Tin with limited exploration for Lithium. Kyarra • The Company is exploring for base metals, in particular cobalt within the Kyarra Project area. The geology consists of shallowly dipping sediments and volcanic rocks of the Yerrida Basin where base metal anomalism has led numerous previous explorers to target sedimentary exhalative style mineralisation. The Company is targeting sedimentary-hosted Co-Cu-Ni deposits. Lynas Find • The Company is exploring for rare metal pegmatites in the project area. The geology of the area is dominated by Archaean Pilgangoora Greenstone Belt metasedimentary and metavolcanics units, intruded by granites and pegmatites which are known to host rare metal mineralisation including tin, tantalum and lithium. Previous exploration focused on Tantalum and Tin with limited exploration for Lithium prior to the discoveries immediately south of the Company’s tenements. Stannum • The Company is exploring for rare metal pegmatites in the project area, derived from fertile granites that have intruded the Wodgina Greenstone belt. The Wodgina Greenstone Belt is an arcuate, keel shaped package of Archaean aged meta- sediments and meta-volcanics. Intruded by granite and pegmatite bodies which are known to host rare metal mineralisation. The pegmatites have been mined in the past for tin, tantalum and beryl and are known to host lithium mineralisation. immediately south of the Project area. |

the remainder of the study area. Stannum • Previously released. |
| 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 weighting, or cut off grades were employed. • No metal equivalent values are reported |
| Relationship between mineralisation 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 (e.g. ‘down hole length, true width not known’). |
• No intercepts are reported apart from Stannum (Figure 4). In which the intercept length is reported as a down-hole length. • There is not enough information to determine true width, however the geological assessment of approximately flat lying pegmatite bodies suggests it is reasonable to assume in the vertical hole referenced that the down hole width closely approximates 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 aplan view of drill hole collar locations and appropriate sectional views. |
• Refer to main body of announcement for figures depicting locations of sampling locations and assay results. |
| 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. |
• Other assay results were not significant and have not been reported. |
| 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. |
• Some relevant geological observations are presented in the main body text. • No additional testwork beyond assaying has been undertaken to date. |
| 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. |
Lake Cowan, Stannum and Lynas Find • Follow up RC drilling will be undertaken to confirm the presence and extent of rare metal pegmatites in bedrock. Kyarra • Further sampling and mapping will be undertaken to assist drill targeting. |
