Metalicity Limited (ASX: MCT) (“ MCT ” or “ Company ”) is pleased to announce significant technical developments at the Admiral Bay Project, located in the Kimberley region of Western Australia, which interprets possible shallower zinc targets adjacent to the existing deposit.
The Admiral Bay project is currently held by the Company’s 82.5% owned subsidiary Kimberley Mining Limited (KML) which is proceeding with an IPO on the TSX-V when market conditions permit (see ASX announcement dated 28 February 2019).
While the Company has significantly re-focussed its exploration strategy to develop its copper and other base metals projects in the Paterson Province and Fraser Range, Metalicity remains committed to supporting the project throughout the listing process.
Metalicity believes these technical advances significantly enhance the investment case for KML and also delivers value for the Company which will continue to hold a major interest in KML.
The 2017 Canning Basin SEEBASE model provides a new view of architecture and evolution of the basin geometry and the Company has reprocessed this data in the Admiral Bay area to interpret data for base metal structures – with the model originally developed for the oil and gas industry.

Recent work by the Company and their consultants (on the behalf of KML) has identified a significant basement high in the reprocessed SEEBASE data, immediately to the south east of the Admiral Bay mineral resource (see Figure 1).
Interpretation in this area was assigned a confidence interval of 85% by the Geological Survey of Western Australia and their consultants Frogtech Geoscience.

The Company believes it is likely the mineralisation host sequence in the area of the basement high will be domed and potentially form a quality trap for mineralised fluids with enhanced mineralisation.
It is also possible the host sequence over the basement high will be at a higher RL (reduced level) than that intersected in three nearby historical oil wells, Leo-1 and Great Sandy 1 and 2. Detailed reprocessing of the seismic line through Leo-1 and Great Sandy wells is in progress and initial review supports the presence of the basement high and draping or doming of overlying geological sequences. This could mean mineralisation is at a shallower level and is considered as part of the detailed reprocessing and interpretation of the seismic data.
Reviews of historic petroleum data were completed as part of this work. A detailed top of Nita Formation structure contour map was located. The Nita Formation is the key mineralised unit in the Admiral Bay Mineral Resource. This map illustrates the depth to the top of formation in much the same way as a topographic map depicts the elevation of the earth’s surface with contours. This mapping has identified interpreted closed domes within the mineralised sequence making for enhanced traps for mineralising fluids Figure 2. One such

trap corresponds with historic drilling, including the high-grade zone within the mineral resource. The Company postulates these trap sites pose valid drill targets for enhanced mineralisation.
Work completed by our geophysical consultants, Fathom Geophysics and CGG, the owners and providers of Falcon® Plus Airborne Gravity gradiometer system, suggest enhanced mineralisation may potentially be identified with a Falcon® Plus survey. Falcon® Plus surveying is an airborne exploration technology which is quick to execute and is non-ground disturbing. Such a survey is subject funding within Kimberley Mining Limited.
The Ordovician stratigraphy, including the Nita and lower Carribuddy Formations hosting Admiral Bay mineralisation, are exceptionally consistent above the Proterozoic basement. The Company is of the view that the observed zinc and lead mineralisation in Leo-1 and Great Sandy (1 & 2) wells may be present at a shallower depth above the SEEBASE high. Seismic interpretation is ongoing to test this theory.
Commenting on the additional interpretation at Admiral Bay, Metalicity CEO Mat Longworth said:
“ We are very pleased with the technical developments at Admiral Bay, which suggest the project may also host additional quality zinc targets.
“The work completed to date has provided robust geological interpretation which we believe has the potential to significantly improve attractiveness of our zinc assets – which already represents one of the world’s major undeveloped zinc deposits.
“It may even be possible, with the completion of a Falcon ® Plus Airborne survey, to screen and rank traps sites based on the gravity signature and thus target any future drilling more effectively,” he said.

Explanatory Notes:
SEEBASE:
The Current SEEBASE (Structurally Enhanced view of Economic BASEment) was released in Late 2017 and is the latest enhancement the Canning Basin study which includes significant additional information. This provides a substantial improvement in resolution and structure interpretation. The initial data was developed for the Oil and Gas industry and its application to exploration for metalliferous deposits is growing in acceptance.
The full interpretation is presented in (Figure 3) which shows the extents of the study. Admiral ay is located on the northern margin of the Willara Sub Basin on the edge of the Broome platform. Importantly the study covers the Paterson Province and has been used extensively by the company and our consultants in targeting mineralisation.

Figure 3 – 2017 Canning Basin SEEBASE Area of Interest (Source: Geological Survey of Western Australia, Report 182 – 2017 Canning Basin SEEBASE Study and GIS Package)
The methodology of the 2017 SEEBASE Project used field data to interpret basement, basement terranes, depth to basement, regional structural geology and the basement composition. To achieve the aims, the project required extensive basement and potential field processing and interpretations to be integrated with seismic and well analysis. This integration has proven powerful and has illustrated the strong basement control on the distribution and location of basin elements. This also delivered relative confidence percentages to areas modelled, where several forms of data were used to derive the model results. Admiral Bay is situated, in an area noted at an 85% confidence due to “Moderate basement depth - widespread 2D seismic data and a few wells”.
Therefore, the Company believes the basement high modelled in the SEEBASE processing has a relatively high confidence. It is likely the sediments overlying the high are domed potentially forming trap sites for mineralisation. Furthermore, given the Canning Basin stratigraphy is well defined not only through previous petroleum exploration, but more locally within the Admiral Bay Mineral Resource model, extrapolations that basement dome structures reflect upward through the stratigraphy giving a stratigraphically higher (or shallower depth wise) location to known formations is a possible and reasonable assumption.
Falcon® Plus Gradiometer Survey:
==> picture [133 x 28] intentionally omitted <==

The Falcon® Plus airborne gravity gradiometer (AGG) surveys provide the ability to provide superior mapping of basement topography to depths exceeding 6,000 metres. A recent case study published on CGG’s website (https://www.cgg.com/en/What-We-Do/Multi-Physics/Case-Studies/Success-in-the-Canning-Basin) details recent work within the Fitzroy Trough and Gregory Sub-basin within the greater Canning Basin. A noteworthy statement made by CGG:
“ A sequence of Ordovician carbonate and shale bearing formations of relatively constant thickness overlying the metamorphic basement is clearly defined as gD and GDD highs in the AGG data. The fault structure of the platforms and terraces is well-defined by, with low GDD values in the fault heave areas of these formations. In the northern part of the survey, thickness variations in the Ordovician-Silurian Carribuddy Group are linked to large listric growth faults, defining the WNW Fitzroy Trough trend.”
The results of that survey delivered better 3D definition of the sub-basin architecture and a detailed structural interpretation allowing for more succinct exploration to be planned and executed on that case study Project. Hence, with Falcon® Plus’s depth penetration ability and low-noise characteristics contributing to improved imaging of deeper layers - paramount for Admiral Bay base metal mineralisation, initial modelling of Admiral Bay mineralisation at various depths and sizes indicates that detectability of higher tenure mineralised zones is possible using this gravity survey method:
==> picture [455 x 129] intentionally omitted <==
Table 1 – Admiral Bay Base Metal modelling results.
Therefore, given the success of Falcon® Plus elsewhere within the Canning Basin in mapping a similar stratigraphic unit, and that the survey methodology has the noise cancelling with depth penetration capabilities, coupled with the recently acquired top of Nita Formation structure map, the likelihood that a survey that defines zones of higher contrasting units, within the base metal mineralised host units may provide a high priority, high confidence target for significantly more endowed base metal mineralisation.
Leo-1 & Great Sandy 1 & 2 Wells
Leo-1 well was drilled by the Sydney Oil Company (164) Pty Ltd in July 1988 and finished at a total depth of 2,411.3 metres in August 1988. The initial loggers noted from the logging of the “Upper Nita Unit”, “The limestone is white, off-white to light grey, cryptocrystalline to microcrystalline, with sulphides concentrated in the upper 10 metres and rare white barite” The unit described corresponds to a drill hole depth of 1,540 to 1,550 metres.
Subsequent logging of core cut within the well Leo-1 by Command Petroleum NL noted the development of sulphide mineralisation (Sphalerite, Galena and Chalcopyrite) within the interval of 1,575.6 to 1,588.6 metres. Sulphide occurrences were noted throughout this interval and the extents are unknown due to the limit of the core cut.

Great Sandy 2 essentially twinned the Great Sandy 1 Well. Both were targeting the prospectivity of the Nita Formation for oil and gas, Great Sandy 2 was drilled to a total depth of 1,600 metres, and Great Sandy 1 drilled to a depth of 1,771 metres. Both wells were drilled in 1981 by Meridian Oil NL.
In 1982, Meridian Oil NL commissioned a petrographic report on Great Sandy 1 Nita Formation intersections. The core was from an interval of 1,508 to 1,525 metres down hole. Notes from the report state; “Sulphide mineralisation with Galena and pyrite seems to be related to late stage dolomitization because these mineral phases form void-fillings and coatings on crystal faces that project into voids.”
The comments noted within the well reports confirm the widespread nature of the Admiral Bay base metal mineralisation, these notes further confirm the periphery of this dome structure discussed above is indeed mineralised. The mineralised basin brines that were the fluid that deposited the mineralisation observed in Leo-1 and the Great Sandy Wells, we are interpreting to be trapped at or near this domal structure observed in the SEEBASE imagery and will hopefully confirm through the 2D seismic reprocessing.
Further details around the Leo-1 and Great Sandy Wells are provided in Table 1, Sections 1 and 2.
2D Seismic Interpretation
Our geophysical partner has been contracted to re-process the Capricorn C84-05 2D seismic line that was captured in November 1984. This seismic line is coincident with the Leo-1 and Great Sandy wells. Whilst the raw data is time constrained, the re-processing coupled with the publicly available well data on offer will generate an original depth constrained stack, coupled with a PTSM and PSDM stack allowing for an accurate interpretation of the stratigraphy and structural controls coincident with the SEEBASE modelled basement high.
Converting the time constrained stacks to depth constrained will allow for the succinct interpretation of the known stratigraphic units and associated controls. Extrapolation of the observed mineralisation with Leo-1 and the Great Sandy wells will allow for a reasonably accurate depth constraint to possible trap sites within this interpreted dome structure illustrated in the SEEBASE modelling. Overall, the combination of this 2D seismic interpretation utilizing known well data, coupled with the depth to top of Nita Structural map with preliminary modelling of Falcon® Plus gradiometer surveying illustrating that higher tenure base metal mineralisation may be defined at the average depth of the Admiral Bay mineral resource, and the high confidence domal structure observed within the SEEBASE modelling lends to a significant step change in the definition of further resource delineation work capable of potentially delivering higher grading base metal mineralisation.
