ASX RELEASE
Resolution Minerals Managing Director Duncan Chessell commented:
We are very pleased to have demonstrated “proof of concept”, through the intersection of thick carbonaceous, pyritic and dolomitic siltstones and shales akin to the Barney Creek formation which hosts the well-known world class HYC / McArthur River lead zinc Mine owned by Glencore. The program has improved our understanding of the geology and takes us one step further on the journey to a potential major discovery in an underexplored prospective region.
The Benmara Project is an exciting large scale potential green-fields sediment hosted battery metals project in one of the last few sedimentary basins in Australia to be explored. We have successfully intersected thick target rock units derived from recent geochronology research as part of the Geoscience Australia’s $225m Exploring-For-The-Future initiative. This initiative for the first time, identified the potential of and stratigraphically links the Benmara Group with the Lawn Hill Platform and Southern McArthur Basin, both of which are known to host large battery metal deposits, such as McArthur River, Lady Loretta, Walford Creek and Century Deposits.
The next step will be to follow up these units along strike and vector towards mineralisation, utilising alteration and trace element haloes defined by our maiden drilling program assay results and further geophysics surveys. 2022 will be a very busy and exciting time for RML.

ASX RELEASE
Summary
Resolution Minerals Ltd (ASX: RML ) ( Resolution or Company ) is pleased to announce that it has intersected thick, prospective, pyritic, carbonaceous and dolomitic siltstones and shales associated with flat lying VTEM anomalies, at shallow depths during the maiden RC Drilling program on the Benmara Project. Assay results returned elevated lead, zinc and silver (Pb-Zn-Ag) of up to 198.5 ppm Pb in HoleID: 21BM006; 357 ppm Zn in HoleID: 21BM007; 307ppm Cu in HoleID: 21BM013; and 0.65ppm Ag in HoleID: 21BM009. These values are in the order of 5 x background for an average shale (AusIMM Field Geologists Manual, 2011).
Highlights
-
RC Drilling confirms 3km long, 1km wide and up to 194m thick packages of highly prospective pyritic shales and siltstone rock units interpreted to be Benmara Group and equivalent to host rocks for world class deposits in the region. Regional examples are McArthur River, Lady Loretta, Walford Creek and Century Deposits
-
RC drilling assays also reported anomalous Fe-Mn carbonate alteration and elevated thallium (Tl) trace element within the Benmara Group increasing to the east. There is a similar characteristic halo around the HYC, Lady Loretta and Century deposits and indicates likely proximity to mineralisation at RML’s Benmara Project
Drilling followed up conductive rock units identified by the Company’s airborne VTEM geophysics survey in 2021. These conductive units can be excellent trap sites (reductive units) for base and battery metal mineralisation, encountered over more than a 3km strike length and 1km width and remain open in all directions. As seen at Walford Creek, the target stratigraphy includes fine-grained sandstones, siltstones and shales, including carbonate alteration and pyrite rich zones (Northwest Mineral Province Deposit Atlas, 2019). The target unit overlies a thick dolomite unit which is possibly equivalent to the Walford Dolomite (or the Tina Dolomite) and contains bright green, strongly altered tuff layers, which may be equivalent to tuffaceous marker horizons present at Walford Creek. We are targeting sub basins with the aid of tuff “marker” horizons to determine where we are in the stratigraphy. At Walford Creek a positive correlation has been noted between the degree of alteration of the tuff marker horizons and the grades of mineralisation present in the underlying unit (Northwest Mineral Province Deposit Atlas, 2019).
This is a fantastic outcome given the conductive sedimentary units lie beneath a blanket of black clay and aeolian cover negating the use of surface geochemical techniques, and it’s only through modern geophysics that targets like this are identified.
RML submitted 3m composite multi-element samples for the entire program to allow for geochemical vectoring. Analysis of the geochemistry has revealed some excellent vectors known to be associated with halos present at Lady Loretta, HYC and Century base and battery metal deposits (Leach et al, 2005).

(1) The presence of Fe-Mn alteration associated with the prospective units
-
(2) The presence of anomalous trace element thallium (Tl) increasing from the WNW to ESE

ASX RELEASE
Immediate follow up drill targets have been defined based on geochemical vectors combined with the position of prospective structures and interpreted units along strike and VTEM results.
RML is very positive about this project that in addition to planning further drilling, RML has signed a contract to undertake further VTEM in 2022 on their newly acquired ground. Final plans for these programs will be announced in the new year.
A full desktop review is planned over the wet season (summer months), including analysis of thin sections and geochronology to further enhance the Company’s understanding of the host rocks and alteration ahead of next field season. Drilling approvals will be submitted well ahead of dry season.
Resolution is excited to be one of the first movers in South Nicholson Basin and has received significant positive interest from multiple parties regarding the project.
Detailed Geological Interpretation
Vectors to mineralisation
Alteration & Trace Element Haloes
Fe-Mn carbonate alteration halos are present at Lady Loretta, HYC and Century deposits and are thickest immediately surrounding the ore. The halo can extend for distances varying from the hundreds of metre through to the tens of kilometre scale (Leach et al, 2005). The RC drilling intersected values of 0.1-0.2% Mn and 3-5% Fe within a carbonaceous shales and siltstones.

Figure 4 Schematic section of typical Fe-Mn carbonate alteration halos associated dolomitic siltstone-hosted deposits of northern Australia e.g. Lady Loretta, HYC and Century (Leach et al, 2005)
Thallium (Tl) is an important geochemical indicator (trace element) and vector to stratiform Zn-Pb-Ag mineralisation and occurs at values of 100 to 1,000 ppm through the Zn-Pb ores and decreases to values of less than 1 ppm at distances of 1 to 20 km along the favourable horizon (Leach et al, 2005). The Company’s Benmara drilling intersected a maximum value of 42ppm Tl, with multiple samples exceeding 1ppm Tl indicating these holes could be within kilometres of an ore zone (Figure 5). There is an increase in Tl from west to east within the carbonaceous siltstones and shales.

ASX RELEASE
RML previously reported results from a VTEM Max survey (RML ASX Announcement 9/7/2021) which was utilised for RC drill targeting. VTEM is a geophysical technique which can directly detect massive sulfides and/or identify conductive formations and thus could also detect reductant carbonaceous or pyritic shales in certain conditions, which are an excellent trap site for copper or base metal mineralisation.
2.5D Inversion of Resolution’s Airborne VTEM geophysics survey data
Resolution Minerals is a small but innovative exploration company and is always seeking to deploy the latest cutting edge exploration techniques with the aim of better exploration outcomes. Recently RML engaged Intrepid Geophysics to undertake a 2.5D Airborne Electromagnetic inversion on the Benmara VTEM Max data, which was received from Geotech with typical industry standard CDI and 1D inversions.
The 2.5D AEM inversion technology was developed in-house by Intrepid Geophysics and produces very clean and spatially accurate images of subsurface conductivity in both cross section and plan and can model topography and irregular subsurface structures. The software was developed to facilitate accurate targeting of ore bodies, mapping of geology and geological structures and is much more cost effective than alternatives such as follow up ground EM surveys.
The exploration team was very pleased with the correlation of forward modelling to actual drilling results and this gives the Company confidence to explore in the region using this technique.

-
Deposit of 40.9 Mt @ 2.03% CuEq (including 50,300t of contained cobalt metal)
==> picture [320 x 448] intentionally omitted <==
Base metal mineralisation at Walford Creek is predominantly hosted in pyritic sedimentary units and associated dolomite (Mt Les Siltstone), which abut the steeply dipping Fish River Fault Zone for a strike length of 10km. This same fault system extends west across the NT border onto Resolution Minerals’ Benmara Project ( Figure 3 ).
The Mt Les Siltstone of the Fickling Group is stratigraphically and temporally equivalent to the Riversleigh Siltstone of the McNamara Group (both part of the Lawn Hill Platform), and the Crow Formation of the Benmara Group (South Nicholson Basin), which has been identified on Resolution Minerals’ Benmara Project . All three formations contain reduced, organic rich shales which make excellent depositional sites for base metal mineralisation (i.e. trigger metal precipitation).
Base metal rich fluids flow up along the contact of the Peter Creek Volcanic “wall” (akin to the Murphy Inlier at Benmara) bringing metalliferous fluids in contact with reductive sedimentary units PY1, PY3 of Mt Les Formation in QLD, equivalent to pyritic shales and siltstones present at Benmara
