Highlights
- Surface rock samples taken while geological mapping and prospecting for tin have returned highly elevated lithium values in several areas across the Aberfoyle project covering an area of at least 8 km by 4 km (Figures 1, 2 and 3)
- Ten samples returned ≥0.1% Li 2 O with a maximum of 0.57% Li 2 O
- Independent X-ray diffraction analyses has confirmed the host mineral to be zinnwaldite, the major mica host of significant lithium projects in Europe and elsewhere in the world
- Independent third-party check analysis has confirmed original laboratory analyses
- Field teams have been mobilized to undertake follow up geological mapping, rock and soil sampling
- The district-scale project is underexplored and has never seen modern systematic exploration for tin and tungsten and lithium has never been targeted
"We are very excited to have encountered significant values of lithium in our surface work at Aberfoyle , which is also a highly prospective tin and tungsten project," commented Chris Donaldson , Executive Chairman. "While prospecting for tin and tungsten, the Company made an unanticipated discovery of lithium mineralization at the Project, which has never been explored for lithium. The lithium grades are in line with mica-hosted projects in Europe and we are eager to continue the field work to complete more targeted sampling and follow-up. The prospectivity at Aberfoyle is an excellent complement to its more advanced Great Pyramid tin project also located in NE Tasmania . Tin, lithium and tungsten are indispensable for decarbonization and TinOne is in an excellent position to create shareholder value."
Key Results
During reconnaissance exploration programs for tin across the Aberfoyle project, TinOne geologists sampled mica (greisen) altered granite, where ten samples returned highly elevated lithium values of 0.1% Li 2 O or above with a maximum of 0.57% Li 2 O (Table 1, Figure 2).
Greisen alteration of the type sampled at Aberfoyle is a typical alteration style associated with many tin deposits globally and is also associated with certain large scale lithium deposits, where the mica alteration minerals are lithium-bearing. Lithium grades (expressed as Li 2 O) in these mica-hosted deposits are typically in the range 0.3-0.7% Li 2 O (Table 2).
The elevated lithium samples at Aberfoyle come from three separate areas over an area of more than 8 km by 4 km (Figure 2), suggesting that the lithium occurrences are not isolated and may be part of a previously unrecognised lithium camp.
The main area of elevated lithium sampled to date covers the historic Guinea Pig and Dead Pig small-scale tin mining prospects with five of the seven rock samples collected over an area of approximately 600 x 250 metres returned values over 0.1% Li 2 O and up to 0.57% Li 2 O (Figures 2 and 3).
Approximately 2 km north of the Guinea Pig prospect, two samples in the Ockle Creek area returned 0.10% and 0.12% Li 2 O, respectively (Figures 2 and 3).
In addition, another sample collected at the Tasmania Creek prospect to the northeast returned 0.22% Li 2 O and one sample a further 1 km north returned 0.1% Li 2 O (Figure 2).
Check Analysis and Mineralogical Analysis
Samples that returned 0.1% or more Li 2 O were sent for umpire analysis at SGS Townsville, Australia and returned values consistent with the original ALS results (Table 1), thereby confirming the significance and validity of the original laboratory results.
Selected higher grade samples were also analysed by X-ray diffraction 12 (XRD) at the Minerals Resources Tasmania laboratory and confirmed the presence of substantial quantities of the mica zinnwaldite {KLiFeAl(AlSi 3 )O 10 (OH,F) 2 }, which is globally the most important mica-host for hard rock lithium deposits (Table 2).
Next Steps
TinOne has mobilized its field team to undertake geological mapping and additional systematic and targeted rock sampling in the areas identified to-date and in other areas of similar altered granite known from historic records. Soil sampling in these areas is also underway in order to define the extent of anomalous lithium within the granite host.
Results from ongoing rock sampling will be released in the coming weeks as soon as they are received.

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 mineralised 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 mineralised 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.
Mineralisation 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.
Sample Methodology
Rock samples reported here were collected by experienced geologists from outcrop, float and historical mining spoil dumps. Samples were typically 1.5 to 2.5 kg and were placed in pre-numbered, calico bags and then into large rice sacks which were sealed for shipping. Due to the nature of the available sample media, the samples are not continuous channel samples and consist of multiple individual small rock pieces collected from an area considered representative of the material being sampled.
Quality Assurance / Quality Control
Rock samples were shipped to ALS Limited in Brisbane, Australia for sample preparation and for analysis. The ALS, Brisbane facilities are ISO 9001 and ISO/IEC 17025 certified. Tin and tungsten are analysed by ICP-MS following lithium borate fusion (ALS method ME-MS85), overlimit results are reanalysed by XRF (ALS method XRF15b). Forty-eight element multi-element analyses are conducted by ICP-MS with a four-acid digestion (ALS method ME-MS61).
Selected elevated lithium sample pulps were shipped to SGS Townsville for check analysis using a 4-acid digest with and ICP-OES finish (SGS methods GO_DIG41Q100 and GO_ICP41Q100).
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.
