TinOne Resources Inc. announced that further rock sampling has confirmed and expanded the previously reported lithium discovery at its 100%-owned, 9,600 hectare Aberfoyle Project ("Aberfoyle" or the "Project") located in the tier-one mining jurisdiction of Tasmania, Australia. Follow-up surface rock sampling at the Dead Pig and Guinea Pig prospects has returned analyses of up to 1.14% Li2O: a total of 43 rock samples were collected in an area of approximately 1 square kilometre where eleven samples returned grades =0.5% Li2O. Emerging lithium district: the Company holds a dominant ground position over the prospective lithium-hosting granites in north-east Tasmania.

Project is underexplored: The Project has never been targeted for lithium mineralization and has also not seen modern systematic exploration for tin and tungsten. Complementary research has commenced: Mineralogical research has commenced in conjunction with the world-renowned Centre for Ore Deposit and Earth Sciences at the University of Tasmania ("CODES"). Key Results: Follow up sampling at the Dead Pig and Guinea Pig prospects have confirmed the earlier discovery of lithium-bearing rocks.

A further 43 rock samples were collected over an area of approximately 1 square kilometre at the Dead Pig and Guinea Pig prospects where previous reconnaissance sampling returned five samples with elevated lithium values of 0.1% Li2O or above with a maximum of 0.57% Li2O (see the Company's news release dated February 8, 2023). This new round of sampling has returned eleven samples with Li2O > 0.50% and a maximum value of 1.14% Li2O. Sampling to date has defined an area of approximately 12 hectares within which the >0.20% Li2O samples occur.

Preliminary interpretations indicate that the higher-grade mineralization occurs in NNW-trending parallel zones of so far defined up to 250 m in strike length. Further work is required to better define the surface morphology of the mineralization and the width of mineralized zones. Next Steps: TinOne's field team continues 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.

In order to define the extent of anomalous lithium within soils derived from the granite host, soil sampling in these areas has been completed for a large part of EL27/2004 with first results expected imminently. In addition to the ongoing work in the lithium-anomalous areas identified on EL27/2004 to date, the Company plans a program of mapping and sampling on the southern outlier part of EL27/2004 at Royal George. This part of the tenement covers an area around the historic Royal George tin mine and is hosted by a similar tin granite to the Dead Pig area.

As such, the area is considered highly prospective for both lithium and tin. There has been no effective on-ground exploration in this area for approximately four decades. The Company has provided samples to CODES for mineral chemistry analytical work to determine the distribution of lithium within the minerals that comprise the lithium-bearing rocks.

CODES has an ongoing project entitled "Tasmanian Tin Granites" and has access to highly skilled personnel with significant experience and knowledge in the field of tin granites and geometallurgical studies. This analytical work will inform future studies into the metallurgical characteristics of the lithium mineralization. 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. 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 lithology being sampled.
