All intersections are downhole widths, true widths are uncertain. |
TinOne drill hole numbering is in the form 22GPRCXXX for reverse circulation (RC) holes and 22GPRDDXXX for diamond holes with numbering allocated in sequence. |
Analytical results have been received for holes 22GPRC002, 003, 004, 005, 006, 007, 009, 011, 012, 013, 014, 016, 017, 018A, 019, 021, 022 and 024. Hole 22GPRC020 failed at 12 metres and was not assayed. The target area for this hole was drilled by 22GPRC021. |
Diamond holes completed to-date and with assays pending are 22GPDD10 and 22GPDD023 (Part). Diamond tail extensions have been completed for RC pre-collar holes 22GPRC003, 22GPRC004, 22GPRC005, 22GPRC006, 22GPRC014 and 22GPRC021 with assays pending for 22GPRC018A. |
Results reported here represent data from both the upper reverse circulation component and the lower diamond drill component of holes 22GPRC014 and 22GPRC021. The reverse circulation components have been previously reported (see TinOne news releases
Results have been received for 3,816 metres of the Company's completed 4,687 metre drilling program at Great Pyramid. These results represent complete results for 18 RC reverse circulation drill holes, results from two diamond cored holes and partial results from one diamond cored hole, in addition to results from six diamond tails and partial results from one other diamond tail.
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 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 surface2.
Historic Resources and Drill Data1
A historical mineral resource estimate was completed on the

2. The Historical Estimate was prepared using the 2012 Australasian Joint Ore Reserves Committee Code (JORC). The Historical Estimate was not completed using CIM Definition Standards on Mineral Resources and Reserves and is not supported by a technical report completed in accordance with National Instrument 43-101. |
3. The estimation of the Historical Estimate utilized close spaced historic percussion (~85%) and lesser diamond drill holes with drill spacing in the estimation area typically 15 x 30m and locally closer. 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. Continuity of tin grades was characterised by indicator variograms at 14 indicator thresholds. The estimates are extrapolated a maximum of approximately 30 metres from drilling. Gemcom software was used for data compilation, domain wireframing, and coding of composite values, and GS3M was used for resource estimation. Resources were estimated into 15 by 30 by 3 m blocks (across strike, strike, vertical) aligned with the 067o trending drilling grid. |
4. The reader is cautioned that the Historical Estimate is considered historical in nature and as such is based on prior data and reports prepared by previous property owners. The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. A qualified person has not done sufficient work to classify the Historical Estimates as current resources and TinOne is not treating the Historical Estimates as current resources. Significant data compilation, re-drilling, re-sampling and data verification may be required by a qualified person before the Historical Estimates 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. |
5. The Company has determined that the Historical Estimate is reliable, and relevant to be included here because it was estimated using close spaced drilling with modern geostatistical methods and software by an experienced resource geologist and provides a guide to the location of the Great Pyramid mineralised zone. This will be used to assist in targeting drilling to undertake testing of the extent and grade of the mineralised system. |

Forward–looking statements and forward–looking information relating to any future mineral production, liquidity, enhanced value and capital markets profile of TinOne, future growth potential for TinOne and its business, and future exploration plans are based on management's reasonable assumptions, estimates, expectations, analyses and opinions, which are based on management's experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things, the price of gold and other metals; no escalation in the severity of the COVID-19 pandemic; costs of exploration and development; the estimated costs of development of exploration projects; TinOne's ability to operate in a safe and effective manner and its ability to obtain financing on reasonable terms.
These statements reflect TinOne's respective current views with respect to future events and are necessarily based upon a number of other assumptions and estimates that, while considered reasonable by management, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward–looking statements or forward-looking information and TinOne has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: the Company's dependence on early stage mineral projects; metal price volatility; risks associated with the conduct of the Company's mining activities in
