TinOne Defines New Zone of Strong Lithium-in-Soil Anomalism at Its Aberfoyle Project, Tasmania, Australia
Vancouver, British Columbia (July 20, 2023) - TinOne Resources Inc. (TSX.V: TORC) (OTCQB: TORCF) (Frankfurt: 57Z0) ("TinOne" or the "Company" - https://www.commodity-tv.com/ondemand/companies/profil/tinone-resources-inc/) is pleased to announce that it has defined a new zone of anomalous lithium-in-soil at its 100%-owned, 9,600 hectare Aberfoyle Project located in the tier-one mining jurisdiction of Tasmania, Australia.
Highlights
- Definition of a new zone of broad lithium-in-soil anomalism:
The Dalrymple area is 9 km southeast of the Dead Pig-Guinea Pig anomaly and measures approximately 2.6 by 1.2 km. A coherent anomaly is emerging near the southeast extent of the Dalrymple area with peak lithium in soils of 1,730 ppm (0.37% Li2O). Infill and additional soil sampling are warranted to fully constrain the size of the anomalous footprint.- Significant lithium potential: The presence of broad zones of lithium-in-soil anomalism suggests the Aberfoyle project is emerging as a significant lithium exploration play. Prior to the Company’s 2022-2023 exploration programs, Aberfoyle has never been targeted for lithium mineralization.
- Exploration through a new lens: New results from Aberfoyle will be used to guide lithium-focused exploration initiatives across the Company’s highly prospective portfolio of lithium-tin-tungsten projects in northeast Tasmania.
“The final results from our recently completed reconnaissance-style soil sampling program at Aberfoyle clearly demonstrate the significant lithium potential of the project,” commented Chris Donaldson, Executive Chairman. “We have now identified multiple zones of strong lithium-in-soil anomalism which support the potential scale of lithium mineralization. Plans are underway to follow-up and expand on these anomalies with infill soil lines as well as new lines to expand open-ended anomalies. We continue to be pleased with results from the Company’s exploration activities at Aberfoyle as we work towards defining a new lithium district.”
Key Results
Reconnaissance-style soil sampling has been completed across the Aberfoyle project (Figure 1). Initial soil sampling was completed on a wide-spaced 200 x 400 m grid, with more detailed sampling on a 50 x 200 m grid across the Rex Hill area (Figure 1). One infill east-west oriented soil line was completed at Dead Pig-Guinea Pig with samples taken at 100 m intervals, midway between two 400 m spaced lines. Results have now been received from all 657 samples collected and the new results, primarily from the eastern side of the project, build on previously released results (see April 26th, 2023 news release).

The soil geochemical data define multiple broad zones of lithium anomalism (Figure 1) highlighted by:
- The newly defined Dalrymple area measures 2.6 by 1.2 km at the 220 ppm (0.047% Li2O) cutoff. The broad zone of lithium anomalism is open to the south and northeast and is more coherent to the southeast, although additional sampling across the area is warranted to fully constrain the size of the anomaly. Only 13 rock samples have been collected across this broad soil anomaly (up to 0.06% Li2O), which were sampled primarily for tin mineralization.
The prospective Devonian granites at Dalrymple are partially covered by relatively shallow (80 m thick) Permian aged sediments (Figure 1). The occurrence of highly anomalous lithium in soil immediately adjacent to the boundary between the lithium-bearing granite and the cover rocks indicates the potential for lithium anomalism to persist under cover at depths amenable to shallow drilling.
- The Dead Pig-Guinea Pig anomaly measures 2.3 by 0.8 km at the 220 ppm (0.047% Li20) cutoff. Rock samples collected from across the anomaly returned Li2O values of up to 2.0% (float) and 1.1% (outcrop) with 33 samples yielding values over 0.1% Li2O (465 ppm Li) (see April 26th, 2023 news release).
- Rex Hill east area spans four 400 m spaced sample lines where the highest Li values (e.g., 416 ppm Li) are from the eastern ends of the lines. The emerging anomaly measures 1 km north to south and is open to the east.
- Follow-up geological mapping and rock sampling together with infill and expansion, tighter-spaced soil lines will be completed across the new soil anomalies to better define their footprints and develop vectors to higher-grade zones.
Detailed multi-element analysis of all soil geochemical data and integration with new geological and structural mapping and new rock geochemical data will be completed and the results are expected to define potential drill targets at Aberfoyle. Importantly, new insights from this work will also help guide future exploration programs across the Company’s portfolio of highly prospective tin-tungsten-lithium projects in northeast Tasmania (Figure 2).
The Company is also currently awaiting assay results from samples of historic drill core from Aberfoyle stored at the Mineral Resources Tasmania (MRT) drill core storage facility. The drill core was logged and where micaceous alteration (potentially lithium-bearing) was observed, the core was sampled and submitted for full multi-element geochemical analyses.
Sample Methodology, Analytical Procedures and QA/QC
Soil samples reported here were collected by experienced field assistants using hand sampling techniques with a depth ranging from 30 to 100cm, with an average of 59cm depth. Samples were coarsely sieved in the field with typically 0.5 to 1 kg despatched to the laboratory. Samples were placed in pre-numbered, calico bags and then into large rice sacks which were sealed for shipping. On receipt by the laboratory, they were dried and sieved to -180µm (-80 mesh) with both fractions retained (ALS method PREP-41).
Soil 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 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 historic Aberfoyle (tin) and Storeys Creek (tin-tungsten) 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 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 historic 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 historic 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.
