Drilling commenced at the Great Pyramid project on April 27, 2022 , with three drill rigs currently operating on site, including two Diamond (DD) rigs and one RC rig. The initial program consists of approximately 5,500 metres and has several objectives:
- Test the depth and lateral extensions of the historical resource;
- Test a large-scale IP chargeability anomaly adjacent to the historic resource; and,
- Obtain grade and continuity data utilising modern drill and analytical techniques, within the area of the historic resource.
"We are extremely pleased to report our first results from our Great Pyramid tin project so quickly after listing," commented Chris Donaldson , Executive Chairman. "The results have demonstrated robust grade continuity within the historical resource at grades equal to or above historical grades. In addition, the results provide further confidence that mineralisation extends below the historical resource. Ongoing work will fill gaps in the data coverage, particularly at depth, and allow us to develop our grade distribution model and build our geological interpretation to integrate with the extensive historical database."
Results reported here are predominantly from the upper portions of the project area within the historical resource 1 area and demonstrate consistent tin grades over substantial thicknesses (Table 1). Mineralised intersections were also encountered beneath the historical resource 1 area (Table 1, Figure 3) and demonstrate that in certain areas mineralisation extends to depth below the historical resource 1 area, consistent with historical drill data 2 .
In addition to the RC drill results reported here, an additional 1,102 metres of diamond drilling has been completed within, lateral to and beneath the historical resource area. Drill core processing is underway with an initial 209 metres of core despatched to the laboratory. To-date these diamond holes have intersected alteration and mineralisation over variable thicknesses up to 120m beneath the historical resource area (Figures 4, 5, 6).

About the Great Pyramid Tin Project
Geological Setting
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 suggests 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 .
Historic Resources and Drill Data 1
The previous owners of the Great Pyramid project estimated an Inferred Resource reported under the JORC 2012 guidelines. This resource contains approximately 10,000 tonnes of tin at a grade of 0.2% tin (Table 2). The estimation utilised close spaced historic percussion (~85%) and lesser diamond drill holes with drill spacing in the estimation area typically 15 x 30m and locally closer. Although the resource is defined by close spaced drilling, the resource was classified by the previous owners as Inferred due to the historic nature of the data. The estimate was reported in the independent geological report prepared by Mining One Pty Ltd for TNT Mines Ltd, dated June 26, 2017 .

Sn% CUT OFF | TONNES (Mt) | GRADE (Sn%) | CONTAINED TIN (kt) |
0.1 | 5.2 | 0.2 | 10.4 |
The Inferred Resource was estimated using Multiple Indicator Kriging method of 1.5 metre down-hole composites within a mineralized domain interpreted from tin grade. The estimate is restricted to the area of close spaced drilling and 90% of the resource occurs within 40 metres of surface. Although the limited deeper drilling has encountered mineralized material this was not included in the resource. Additional drilling utilising modern drill techniques, analytical techniques and QA/QC will be required to re-estimate the resource and report under NI 43-101.
1 The reader is cautioned that the above referenced "Inferred Resource" estimates are considered historical in nature and are based on prior data and reports prepared by previous property owners. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves and TinOne is not treating the historical estimate as current mineral resources or mineral reserves. Significant data compilation, re-drilling, re-sampling and data verification may be required by a qualified person before the historical estimate on the Great Pyramid property can be classified as a current resource. There can be no assurance that any of the historical mineral resources, in whole or in part, will ever become economically viable. In addition, mineral resources are not mineral reserves and do not have demonstrated economic viability. Even if classified as a current resource, there is no certainty as to whether further exploration will result in any inferred mineral resources being upgraded to an indicated or measured mineral resource category.
2 Data regarding historical drilling is sourced from Mineral Resources Tasmania online database (MRTMap). In addition, data for 18GPD001 has been sourced from a public announcement by previous owners TNT Mines, November 15, 2018 . However, the "historical drill data" are considered historical in nature and are based on prior data and reports prepared by previous property owners. A qualified person has not done sufficient work to classify the historical data as current and TinOne is not treating the historical data as current. There can be no assurance that any of the historical drill data is representative.
Quality Assurance / Quality Control
Drill core and RC 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).
Control samples comprising certified reference samples, duplicates and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's quality assurance / quality control protocol.
