TinOne Resources Inc. (TSXV: TORC) (OTCQB: TORCF) ( Frankfurt : 57Z0) (" TinOne " or the " Company ") is pleased to announce that it has identified lithium mineralization in historical core samples from its 100%-owned, 9,600-hectare Aberfoyle Project (the " Project ") located in the tier-one mining jurisdiction of Tasmania, Australia .
Highlights
- Definition of a new style of lithium mineralization at Aberfoyle :
- Select drill core samples of mica-rich sedimentary rocks, host to the prospective Devonian granites, returned up to 0.47% Li 2 O at the Storeys Creek target area.
- Strong lithium mineralization, hosted in sedimentary rocks at Storeys Creek, enhances the prospectivity criteria for lithium beyond Devonian aged granites.
- Follow-up surface sampling, geological mapping, mineralogical studies and potential drilling, in addition to further sampling of historical drill core, are warranted to fully constrain the lithium potential of the target area.
- Expanded exploration search space: These new results significantly expand the exploration search-space for lithium mineralization at Aberfoyle and elsewhere across the Company's portfolio of tin-tungsten-lithium projects in northeast Tasmania .
- Emerging lithium district: the Company holds a dominant ground position over many prospective lithium-hosting granites in northeast Tasmania .
"The identification of new lithium mineralization at the Aberfoyle Project significantly opens our exploration search space across the Project," commented Chris Donaldson , Executive Chairman . "From old core that was drilled for tin-tungsten at the historical Aberfoyle and Storeys Creek mines, we have now discovered that mica-rich sandstones proximal to the prospective granites, also carry highly anomalous lithium concentrations. This is a great result as it further confirms the presence of lithium in a new area on the property and opens additional areas for lithium exploration across the district. Plans are now underway to follow-up and expand on these results by way of systematic rock sampling and mapping across the Storeys Creek area focused on mica-bearing sandstones and also the prospective granites. While TinOne's focus remains on our Great Pyramid tin project, where we are currently concentrating on updating the resource, the exciting new lithium finds at Aberfoyle provide significant optionality for the Company."
Drill Core Sampling Program
Based on a thorough compilation of historical surface and underground drill data together with historical underground geological and structural mapping, multiple historical drill holes were selected for further review. Holes were prioritised based on the documentation and logging of coarse mica-alteration, which has shown to be locally related to lithium mineralization elsewhere on the Project (see March 15 th , 2023 news release).
The key drill holes were located at the Mineral Resources Tasmania (MRT) core storage facility at Mornington in Hobart, Tasmania . The core storage facility holds a total of approximately 4,800 metres of drill core from 59 underground holes drilled at the Storeys Creek and Aberfoyle mines. Additionally, approximately 5,500 metres of drill core from 28 holes collared at surface in the Aberfoyle-Storeys Creek area are held at the facility. The core facility also holds approximately 1,400 metres of core from the Royal George area and 380 metres from the Gipps Creek area. In addition to the core held at the facility, detailed logs from most of the historical drilling at both mines are available to the Company – 449 logs of >21,000 metres of drilling at Aberfoyle and 351 logs of >18,000 metres of drilling at Storeys Creek.
At Mornington, drill core from prioritized holes were laid out, relogged, imaged and select intervals were sampled (either half or quarter core) and submitted to the lab for full multi-element geochemical analyses. Collar information, down hole survey data, lithology, alteration and mineralization data for each hole were digitised from historical reports and were replotted in 3D software to better constrain the spatial representation of each sample. For drill holes lacking collar data, sample locations are inferred from historic underground sections (Figures 2, 3, 4). Seventeen samples were collected from drill core from seven holes at the Storeys Creek and Aberfoyle underground mines and another twenty-five samples were taken from surface holes drilled at Royal George, Gipps Creek and Storeys Creek (Figure 1). Selected analytical highlights are listed in Table 1.

Highlights from the sampling program include:
- Storeys Creek – Three of the highest lithium results were from samples of sedimentary rocks representing the host lithologies to the prospective tin-tungsten bearing Devonian granites. Sample TRD006031 from hole U9-38 returned 0.47% Li 2 O (2,190 ppm Li) of a mica-rich altered sandstone cut by discrete quartz veins. This sample was collected approximately 100 m above the deeper granite (Figure 2). Sample TRD006044 from hole U8-1A returned 0.27% Li 2 O (1,275 ppm Li) collected from a sandstone cut by mica-rich veins with associated quartz and sphalerite (zinc sulfide). This sample was collected approximately 50 m above the granite (Figure 3).
The presence of strong lithium mineralization, proximal to the granites at Storeys Creek, improves the Company's exploration model for lithium across the Aberfoyle project. Additional mineralogical work, similar to the initial studies at the Dead Pig target (see March 15 th , 2023 news release) is required to constrain the nature of the sandstone-hosted lithium mineralization. Further sampling (historic drill core) and surface outcrops surrounding the Storeys Creek target are planned to better evaluate the lithium potential of the area.
- Aberfoyle Mine – Samples of drill core from historical underground holes at the Aberfoyle Mine, located 2.8 km south of the Storeys Creek area (Figure 1), returned anomalous lithium values up to 0.20% Li 2 O (Figure 4). All samples were collected from mica-altered granite (greisen alteration) with textures similar to other zones of significant lithium mineralisation such as the Dead Pig target located 6.8 km to the west (1.14% Li 2 O; see March 15 th , 2023 news release). The mineralized granite at the Aberfoyle Mine target is partially covered by relatively shallow Permian aged sediments, therefore, additional core sampling and potentially follow-up drilling are required to fully evaluate the scale of the granite-hosted lithium potential of the area.
New insights from this core sampling program together with results from the upcoming follow-up sampling and mineralogical studies will help guide future exploration programs across the Company's portfolio of highly prospective tin-tungsten-lithium projects in northeast Tasmania (Figure 5). Many of the Company's other projects are also centered on Devonian granites that intruded into Mathinna Group sedimentary rocks and have similarly not been systematically evaluated for lithium mineralization.
Analytical Procedures and QA/QC
Drill core samples were delivered to ALS Limited in Burnie, Australia from where they were forwarded to ALS Adelaide for sample preparation. Samples for analysis were forwarded to either ALS Brisbane or ALS Perth. Both the ALS Brisbane and ALS Perth facilities are ISO 9001 and ISO/IEC 17025 certified. Samples were analysed for lithium and 47 other elements via inductively coupled plasma mass spectroscopy after a four acid digestion (ICP-MS; ALS method ME-MS61).
Control samples comprising certified reference samples (including reference material certified for lithium) duplicates and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's quality assurance / quality control protocol.

About the Aberfoyle Project
The Aberfoyle project area straddles the boundary between the Silurian to Devonian Mathinna Supergroup sedimentary rocks and the Devonian Ben Lomond Granite. The historical Aberfoyle (tin-tungsten) and Storeys Creek (tungsten-tin) mines as well as other vein systems are hosted in the sedimentary rocks and occur as strike extensive systems of sheeted and stockwork veining. Elevated lithium has not previously been reported from the Project area. Historic production 1 from the Aberfoyle Mine was estimated at 2.1Mt at 0.91% tin and 0.28% tungsten and production from Storey Creek was estimated at 1.1Mt at 1.09% tungsten and 0.18% tin.
Historical records and drilling indicate the mineralized vein system at Aberfoyle is up to 60 metres wide, 800 metres in length and extends approximately 400 metres in the down dip direction. The Lutwyche prospect occurs approximately 1 kilometre northeast of Aberfoyle and is comprised of two sets of mineralized veins which can be traced along strike for approximately 750 metres.
An additional sediment-hosted vein system, the Kookaburra, is located 200 metres southwest of the main Lutwyche vein system and is known to be approximately 40 metres wide with an along strike extent of at least several hundred metres.
Mineralization at Storeys Creek is hosted within a 30 to 50 metre wide, north-northwest striking sheeted vein array which dips to the southwest. The system can be traced along strike for 300 metres and extends 400 metres in the down dip direction. The Ben Lomond Granite crops out approximately 1km west of the mine and has been identified at depth at 180 metres below the surface.
Additional poorly known sediment-hosted vein systems occur at Brocks, Eastern Hill and elsewhere in the tenement.
Granite-hosted occurrences are developed throughout the exposed areas of granitoid outcrop and consist of vein, disseminated and breccia style occurrences with associated greisen style alteration. These have given rise to historical small scale hard rock and more extensive alluvial production in the Gipps Creek, Rex Hill , Ben Lomond , Royal George and other areas.
The Company interprets that both sediment- and granite-hosted systems have developed in structural corridors of multi-kilometre extent and that historical exploration has not systematically explored these corridors. TinOne believes systematic exploration of these prospective corridors will result in the definition of high-quality drill targets.
