TinOne Resources Inc. (TSXV: TORC) (OTCQB: TORCF) (" TinOne " or the " Company ") is pleased to announce it has completed its Phase 1 drill program at its Great Pyramid Tin (Sn) Project (" Great Pyramid " or the " Project ") located in the tier one mining jurisdiction of Tasmania, Australia .

Drilling has now concluded with a total of 4,687 metres completed and data compilation and modelling are underway. The program has been successful in continuing to define significant tin mineralization near surface, at depth and adjacent to historical drilling.

• Great Pyramid mineralization extended to approximately 380 metres below surface.
• Interpreted granite source not encountered, therefore mineralization remains entirely open at depth.
• Mineral Resources Tasmania geophysical modelling interprets granite at depth below Great Pyramid in the range of 700 – 1300 metres.
• Mineralization remains open in all directions laterally.
• Integrated stratigraphic-structural model being developed to assist numeric modelling.

"We are very pleased to have completed our Great Pyramid Phase 1 drill program safely and within budget," commented Chris Donaldson , Executive Chairman. "The results of the program have been outstanding in delivering consistent tin intersections from within the area of historical activity and, importantly, outside this area.  These results and geological interpretation indicate that the Great Pyramid system is of significant scale and has only been partially tested, to date.  Our geological team is developing its detailed interpretation and will be using this information to plan our next phases of drilling which will be focussed on fully testing the system."

The 2022 program was designed to:

• Test the depth and lateral dimensions of mineralization within the vicinity of the historical drilling and resource estimate;
• Obtain grade and continuity data utilising modern drill and analytical techniques, within the area of the historic exploration activity; and
• Test a large-scale IP chargeability anomaly adjacent to the historic resource.

Tables 1 and 2 present full results from the 2022 program and compiled results from all historical drilling known from the Great Pyramid area. The tables show that the 2022 program returned results in line with historical data and includes outstanding intersections of higher grade such as:

• 22GPRC012 78 metres @0.51% Sn (see Company news release September 06, 2022 )
• 22GPRC016 51 metres @0.29% Sn (see Company news release September 06, 2022 )
• 22GPRC021 14 metres @0.36% Sn (see Company news release January 18, 2023 )
• 22GPRC022 15 metres @0.45% Sn (see Company news release October 11, 2022 ).

The 2022 Great Pyramid drill program was highly successful in confirming the presence and tenor of significant tin mineralization in the area of historical drilling activity and historical resource estimate. Weighted average tin grade for all 2022 recorded intersections ¹ was 0.23% Sn which is in accord with historical drill data (Tables 1 and 2).

In addition, the program successfully defined significant mineralization at depth below the historical resource estimate in the area of sparse historical drilling.  Highlights at depth included:

• 22GPRC003 (see Company news release November 22, 2022 )
• 18 metres @0.31% Sn from 308 metres downhole
• 5.4 metres @0.46% Sn from 330.6 metres downhole
• 13 metres @0.22% Sn from 359 metres downhole
• 22GPRC006 (see Company news release September 06, 2022 )
• 49 metres @0.17% Sn from 65 metres downhole
• Including 8 metres @0.3% Sn from 86 metres downhole

These TinOne drill holes and the historical data have not defined the lower limit of the system, which remains entirely open at depth.

A relatively minor component of the program was directed to testing the lateral extent of mineralization due to access, with the network of historical drill access tracks being utilized to obtain a more cost effective drill program for this first round of drilling. However, despite this, the program has also delivered significant results laterally away from the historical drilling and resource estimate, with highlights including:

• 22GPRC021 (see Company news release January 18, 2023 )
• 40 metres @0.13% Sn from 58 metres downhole
• 14 metres @0.36% Sn from 128 metres downhole
• 17 metres @0.21% Sn from 181 metres downhole
• 22GPRC002 (see Company news release June 29, 2022 )
• 14 metres @0.18% Sn from 3 metres downhole
• 6 metres @0.22% Sn from 24 metres downhole

These drill holes and historical drill data have not defined the lateral limits of the Great Pyramid system, which remains open laterally in all directions (Figure 2).

Three drill holes (22GPDD010, 22GPRC018A, 22GPRC019, 22GPDD023) were drilled (for a total of 1275.9 metres) to test IP chargeability anomalies to the northeast and east of the area of historical exploration activity. These holes intersected sedimentary rocks of the Mathinna Supergroup with strong hornfels effects at depth and variable amounts of pyrite (interpreted to be both diagenetic and hydrothermal) and minor base metal sulphides. No significant tin mineralization was encountered. The chargeability anomalies may be explained by the presence of pyrite, however more detailed analysis, including petrophysical property measurements, will be undertaken and integration into the broader Great Pyramid geological model undertaken.

The tin systems of northeastern Tasmania are regarded as classical examples of granite-related tin-polymetallic systems (Taylor, R.G. 1979, The geology of tin deposits ).  Well known systems such as Anchor (Taheri and Bottrill, 2005, Devonian granites and associated mineralization in northeast and northwest Tasmania ), Aberfoyle ² , Lutwyche ^2, Story's Creek ² , Rex Hill ² (see TinOne news release July 07, 2022 ) and Royal George ² are hosted in or directly associated with Devonian granites of the S-type alkali feldspar suite and it is generally regarded that the granites are the source of hydrothermal fluids and metals for formation of the systems.  In the Aberfoyle , Lutwyche and Story's Creek systems, the bulk of mineralization is hosted in Mathinna Supergroup sedimentary rocks above the granite body, with deeper mining levels and drilling demonstrating the connection. In these systems a clear zoning from tin-rich at higher levels above the granite zoning downward to higher tungsten content adjacent to and within the granite. The Aberfoyle system is known over a vertical extent of in excess of 300 metres.

It is highly significant that in most respects (mineralogy, metal association, alteration character), the Great Pyramid system conforms to the granite-related model, yet no granite has yet been encountered in the project area.

Mineral Resources Tasmania (MRT) developed an integrated geophysical and geological model for the Scamander Mineral Field, including Great Pyramid (Scamander 3D geological and geophysical model). The Great Pyramid system occurs on a steep gradient ("shoulder") in the MRT model, and the model estimated that the upper granite surface exists at between 700 and 1300 metres below the Great Pyramid system (Figure 3).
( https://www.mrt.tas.gov.au/geoscience/3d_geological_and_geophysical_modelling/scamander_3d_geological_and_geophysical_modelling ).

The TinOne 2022 drill program provided support for this model and the granite association of the Great Pyramid system with the key evidence being the consistent presence in deeper holes of spotted hornfels ³ . However, despite drilling to depths of almost 400 metres below surface, no granite has yet been encountered at Great Pyramid. In the other Mathinna Supergroup hosted systems in Tasmania (e.g. Aberfoyle , Lutwyche, Story's Creek), mineralization continues to the granite contact and also within the granite. By comparison (and in context of the MRT model and observed geology), it can be interpreted that the Great Pyramid system may extend for a significant distance below current drill levels and potentially continue into the interpreted underlying granite.

The mineralization encountered to date at Great Pyramid is interpreted to have two inter-related control mechanisms (Figure 4).

1. Structure - north easterly striking, steeply dipping structures (TinOne observations, historical exploration reports by Aberfoyle Ltd and BHP Ltd) that transect the sedimentary package and are interpreted to have acted as conduits for mineralizing hydrothermal fluids arising from the granite at depth.
2. Sedimentary rock type - not all of the sedimentary sequence is equally favourable for the production of elevated tin grades and therefore certain units are more strongly mineralized. These units tend to be the more quartz-rich sandstone parts of the sequence and it is interpreted that their brittle fracture patterns within the favourable structural domains promotes mineralization.  A challenge is that the Mathinna Supergroup sedimentary rocks were strongly folded at a time before intrusion of the granite magma and formation of the related mineralization.

The interaction of the folded sedimentary geometries, structural zones and interpreted granite is schematically shown in Figure 4. The figure highlights the potential geometries and relationships expected at Great Pyramid and illustrates why in some places the mineralization is more laterally continuous than in other places.  The figure also illustrates that, based on knowledge from other deposits in northeastern Tasmania , mineralization could be expected to continue in favourable host rocks into the interpreted granite contact.

With the successful completion of the Phase 1 drill program, the TinOne technical team has significantly advanced its understanding of the Great Pyramid system and focus has now shifted to interpretation and integration of the various data sets. This interpretation and modelling phase will develop an understanding of the inter-related controls discussed above and guide more efficient targeting of additional drilling and future resource estimation.

TinOne has engaged a PhD-trained expert in the structural geology of northeastern Tasmania and a PhD-trained expert sedimentologist to work together with the TinOne team and an external resource geologist to develop an integrated structural-sedimentological-geostatistical model. This model will inform additional drilling, principally targeting lateral extensions and a resource estimation at the appropriate time.

Table 1: TinOne Resources Great Pyramid RC and core drill results.

Table 2: Great Pyramid historical drill results.

The Great Pyramid deposit is located around a topographical feature known as Pyramid Hill and is hosted by Silurian to Devonian Mathinna Supergroup sandstones.  The mineralization is formed by closely spaced sheeted northeast trending, cassiterite (SnO₂) bearing veins associated with silicification and sericite-pyrite alteration. The deposit style and regional comparisons suggest that a tin-fertile granite exists at depth below the deposit, however this has not been encountered in drilling and the deposit is open at depth. Geological interpretation indicates that certain sedimentary units within the folded Mathinna Supergroup sediments are more favourable hosts and diamond drilling being undertaken by the Company during the current campaign, combined with numerical modelling, will assist in developing a deeper understanding of controls on grade for follow-up drilling.

The deposit is currently known over a strike length of more than 500 metres with an average width of approximately 150 metres. The depth extent of the deposit is unknown with only nine historical drill holes greater than 150 metres deep. These rare deeper holes encountered encouraging tin mineralization to depths of approximately 300 metres below surface ² .
