·     Diamond drilling was used to obtain 1m samples of HQ core which was sawn in half longitudinally. The half core was broken to less than 10cm sized pieces, bagged and sent to the laboratory for assay. This is industry standard work.

·     Reverse Circulation (RC) drilling was used to obtain 1m samples from a 4.5 inch diameter drill hole.  Drilled material was split with an onboard riffle splitter connected to the cyclone to obtain an approximately 3-5kg representative sub-sample that was bagged and sent to the laboratory for assay. This is industry standard work.

·     All core and RC samples were sent for assay after being logged by the geologist.

·     The drill core and RC samples were sent to ALS Laboratories in Zillmere QLD.

·     Samples were crushed to sub 6mm, split and pulverised to sub 75µm in order to produce a representative sub-sample for analysis.

·     Analysis of the diamond drill and RC samples consisted of a four-acid digest and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for the following elements: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sn, Sr, Th, Ti, Tl, U, V, W & Zn. The samples were also assayed for Nb, Sn, Ta, and W using a lithium borate fusion and ICP-MS technique. If over detection on the ICP was reached, then the samples were assayed using XRF. Standards and blanks were inserted at a rate of 10%.

·     All drilling samples were analysed and hence no prior determination of mineralisation was made.

·    Diamond drilling was undertaken by contractors DRC Drilling.  All drilling used an HQ bit with a soft matrix.  Drill rods were triple tube to ensure good core recovery and avoid washing out of cassiterite.

Percussion drilling was undertaken by contractors Schonknecht Drilling, using a face sampling 4.5 inch "Black Diamond" hammer, 137mm PED (polycarbonate diamond) bit and a 4.5 inch, 6m stainless steel rod.  A tight shroud (3mm gap) ensured the holes remained as straight as possible.  A 350psi, 900cfm compressor was used to keep holes dry and ensure all heavy minerals such as cassiterite are recovered.

·    All core intervals are measured and compared with drillers marks to determine actual recovery.  Recovery was generally 100% apart from isolated intervals with poor ground conditions, generally either near surface or in fault zones.

·    Sample recovery is measured and recorded by company trained geology technicians and geologists.

·    Minimal sample loss has occurred.

·    All RC samples are weighed.  This gives a good idea as to recovery for the 1m intervals sampled as the density does not vary significantly.  Recovery is estimated to be very good in general.  A high pressure and volume compressor is used to endure good sample return and to keep holes dry.  No significant water was encountered meaning sample quality is good.  The hole is cleaned out with compressed air after every rod change and no significant volume of material is returned via this process.

·    No relationship can be seen between recovery and grade.  No sample bias is noted.

·    All drill core has been geologically and geotechnically logged to a level of detail to support appropriate mineral estimation, mining, and metallurgical studies. 

·    The six geotechnical holes were logged by qualified specialist geotechnical engineers.

·    All RC cuttings have been geologically logged to a level of detail to support appropriate mineral estimation, mining, and metallurgical studies. 

·    All drill core has been photographed and logging is quantitative in nature, following a strict set of guidelines.  The entire length of the core has been logged. Qualitative logging includes lithology, alteration and textures.

·    Quantitative logging includes sulphide and gangue mineral percentages.

·    All RC logging is semi-quantitative in nature, following a strict set of guidelines, with percentage estimates made.  Representative sub-samples are collected, sieved and generally panned to estimate heavy mineral content.  A sub-set of rock chips are kept in chip-trays for reference.

·    All core is HQ3.  This is sawn in half after fitting together of core across drillers breaks and a reference line marked on the core.  A consistent side of the core is taken for sampling as half core.  This is broken so it will fit in a bag and sent to the ALS laboratory in Brisbane.

·    All RC cuttings are weighed then riffle split to obtain between 3kg and 5kg of sample.  All samples are dry.  The sub-sample is sent to ALS laboratory in Brisbane.

·    Sample sizes are considered appropriate for the material being sampled as the tin mineralisation occurs as cassiterite (SnO₂) within sub-vertical veins that are between 0.05mm and 0.5cm wide (rarely to 5cm) and cassiterite crystals are smaller than vein width.  Vein density varies from about 5/m to greater than 20/m and hence several veins are sampled in each metre.  This compares with sample size that is approximately 10,000 cm³ for RC and 3,200cm³ for HQ Core before sub-sampling.

·    Drilling is at an angle of -60° or less and hence cuts across veins that are sub-vertical (-90°).

·    At the ALS laboratory in Brisbane, the sample of core or RC chips is crushed and split to less than 3kg if appropriate using method CRU-21.  The entire sample or sub-sample is then pulverized in a mill to 85% finer than 75µm using method PUL-23.

·    Tin is a difficult element to analyse as cassiterite is not soluble in acid.  Thus, a sub-sample of the pulverized and mixed material is taken and fused with lithium borate.  The fused bead is then analysed by a mass spectrometer using method ME-MS85 which reports Sn, W, Ta and Nb.  This returns a total tin content, including tin as cassiterite.  Over limit assays of tin are re-analysed using method ME-XRF15b which involves fusion with lithium metaborate with a lithium tetraborate flux containing 20% NaNO₃ with an XRF finish.

·    Other elements are analysed by method ME-ICP61.  This involves a 4 acid (HF-HNO₃-HCLO₄ digest, HCl leach and ICP-AES finish).  This is an industry standard technique for Cu, Pb, Zn and Ag.  A suite of 34 elements are reported, including tin, which is only acid soluble tin in this case and thus can be subtracted from the fusion tin assays to obtain tin as cassiterite.  The acid soluble tin is generally associated with stannite and in the lattice of silicates.  It is generally insignificant is relation to tin as cassiterite at Taronga.

·    Prior to dispatch of samples, the following QaQc samples are added:

o    Certified standards representative of the grades expected are added at the rate of 1 in 40 samples

o    Blanks are added at the rate of 1 in 40 samples

o    Duplicates are added at the rate of 1 in 20 samples for RC.  These are riffle split from the original sample on site.

o    For diamond drilling, the half core is split into two quarter cores every 1 in 20 samples and these are sent as duplicates

·    All QAQC data is within acceptable limits, with re-assay of any out of specification batches undertaken.

·   

·    Twinning of the previous Newmont drillholes has included:

o  11 TMPL DD twins of Newmont DD Holes

o  2 TMPL DD twins of Newmont percussion holes

o  5 TMPL RC twins of Newmont percussion holes

·    All data is recorded on site in Excel spreadsheets and this is later transferred to an Access database - the main data repository.  Detailed protocols for data recording, logging codes etc are used. 

·   

·    All drillholes are pre-planned and located by use of handheld GPS.  Holes were originally sited and angled using compass and clinometer.  This was changed to using Devico gyro navigation for the later drillholes in order to get an added level of accuracy.  All hole collars are surveyed in accurately post drilling with RTKGPS (+-0.1m).

·    All DDH drillholes are surveyed using downhole gyroscopic surveys. 

·    All RC holes are surveyed using downhole magnetic surveys.

·    All holes have surveys approximately every 30m downhole.

·    The grid system used is GDA94, zone 56.

·    Topography is obtained via a Lidar survey flown in late 2022 and is to sub 10cm accuracy.

·    The original drilling undertaken was to better than 50m x 50m spacing. 

·    Twin drilling is selected to represent all 4 zones of mineralisation and the length of the known deposit.

·    The original data spacing is considered to be sufficient to establish the degree of geological and grade continuity appropriate for the JORC classifications applied.

·   

·    The drilling is oriented at 90° to the orientation of the sheeted veins. 

·    The veins are sub-vertical and the drilling is angled at between -25° and -60° to be as close as possible to cutting across the veins at 90°.  Due to difficulties drilling at very shallow angles, especially with RC, a default angle of -60° was adopted for the later drillholes.

·    As drilling was designed to cut the main sheeted veins at as high an angle as possible. The potential for any introduced sampling bias is considered minor.

·    A chain of custody was maintained for all TMPL drilling.

·    The project is secured by two granted tenements: EL8407 and ML 1774, both of which are currently in good standing.  These are held 100% by TMPL. 

·    No joint ventures or other encumbrances are known. The underlying properties are freehold land owned 100% by TMPL apart from a block of Crown Land that covers part of the southern deposit area as defined by Newmont. 

·    The Crown Land is the only land subject to Native Title.  No native title claims existed at the time the tenements were granted but a statewide  native title claim on crown land is believed to exist.

·    No national parks, historical sites or environmental constraints are known.  Recent surveys have identified the "vulnerable" flora species Velvet Wattle.  This is currently being avoided as much as possible and is not considered to be a major constraint moving forward.

·    The only royalty is the state of NSW royalty of 4% on tin mined.

·    Detailed exploration and feasibility studies were undertaken by Newmont between 1979 and 1984.  These have been used where applicable.

·    This work was undertaken to a high standard and all data is considered to be usable.

·    The deposit is a sheeted vein style tin +/-  copper-silver deposit with horizontally and vertically extensive veins of quartz-mica-cassiterite-sulphide+/-fluorite-topaz occurring over a combined area of up to 2,600m by 270m. 

·    The veins vary in thickness from less than 0.5mm to 100mm but are generally between 1mm and 10mm thick and average about 20 veins per metre.

·    The host rock is hornfels derived by contact metamorphism of Permian aged metasediments. 

·    The source of mineralising fluids is interpreted to be an underlying intrusion of the Triassic Mole Leucogranite, a reduced, highly fractionated, A to I type granite.  The metals of interest (Sn, Cu, Ag) are interpreted to have been enriched in the late magmatic fluid of this granite via enrichment of incompatible elements during fractional crystallisation.  Breaching of the magma chamber during brittle faulting in an ENE orientation has tapped these enriched fluids which have subsequently deposited the metals due to changing temperature and pressure conditions and/or mixing with meteoric fluids.

·      See Attachment 1 - Drill Hole Details.

·    All intercepts shown are weighted averages of uncut data.  The intervals are based on a nominal lower cut-off of 0.05% Sn. 

·    The only high grades are due to very thick veins with coarse cassiterite.  These are shown in the table as to leave them out would give an unrealistic view of grade variability. 

·    No metal equivalent grades are quoted.

·    As mineralisation is sub-vertical and while holes dip at between -28° and -60°, actual true widths vary from 88% to 50% of interval widths.

·    True widths are shown in the attached table.

·    Plan view provided.  As results are twins of existing drilling, sections are not shown.

·    Results are twins of old data and only the direct comparison is of relevance here.

·    The accompanying document is considered to represent a balanced report.

·    No other exploration data is reported here.
