Pilot Mountain initial gold finding clarification

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	· Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. · The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	100% Thor Mining plc mineral leases cover the Desert Scheelite prospect area. There are no issues with security of tenure and no known impediments to licence an operation.
Exploration done by other parties	· Acknowledgment and appraisal of exploration by other parties.	Pre - 2012 data is treated as historic data and used as a guide only unless validated. Pre-existing data post-2012 complies with JORC 2012 code.
Geology	· Deposit type, geological setting and style of mineralisation.	Contact metamorphic skarn hosted tungsten.
Drill hole Information	· A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: o easting and northing of the drill hole collar o elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar o dip and azimuth of the hole o down hole length and interception depth o hole length. · If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	Drill hole summary tables provided in text of announcement.
Data aggregation methods	· In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. · Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. · The assumptions used for any reporting of metal equivalent values should be clearly stated.	Data aggregation is based on a cut-off grade of 0.1% WO₃, a maximum internal dilution of 2.4 metres and a minimum mining width of 1.6 metres. Averaging of grades is length weighted. No metal equivalents are reported.
Relationship between mineralisation widths and intercept lengths	· These relationships are particularly important in the reporting of Exploration Results. · If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. · If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg 'down hole length, true width not known').	Estimated horizontal widths have been supplied.
Diagrams	· Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.	Provided
Balanced reporting	· Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	The drill hole data reported includes only the holes selected for the metallurgical test work. The holes and intervals were selected to provide an even spread of holes across the proposed initial mining volume and to result in a composite grade close to that of the reported resource.
Other substantive exploration data	· Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	No deleterious data or issues known which would adversely impact a potential mining operation. The samples reported have been taken to use for metallurgical testing.
Further work	· The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). · Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	Further exploration work including geophysical surveys and drilling will be undertaken but has neither been planned nor scheduled at this stage.

Criteria		JORC Code explanation			Commentary
Sampling techniques		· Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. · Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. · Aspects of the determination of mineralisation that are Material to the Public Report. · In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.			Exploration results are based on HQ sized diamond drill core Industry standard QAQC protocol was adopted with reference material inserted at 10%.
Drilling techniques		· Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc).			Exploration results are based on HQ sized diamond drill core
Drill sample recovery		· Method of recording and assessing core and chip sample recoveries and results assessed. · Measures taken to maximise sample recovery and ensure representative nature of the samples. · Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.			Core recoveries exceed 95%
Logging		· Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. · Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. · The total length and percentage of the relevant intersections logged.			Drill core were logged geologically and photographed for the entire length of the hole.
Sub- sampling techniques and sample preparation			· If core, whether cut or sawn and whether quarter, half or all core taken. · If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. · For all sample types, the nature, quality and appropriateness of the sample preparation technique. · Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. · Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. · Whether sample sizes are appropriate to the grain size of the material being sampled.	Mineralised intervals of core were cut and half core sent for assay. Sample intervals were based on geological boundaries or a maximum of five feet. Industry standard QAQC protocol was adopted including certified reference material, certified blanks and field duplicates making up 10% of the assay samples. HQ drill core is appropriate to the nature of mineralisation reported.
Quality of assay data and laboratory tests			· The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. · For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. · Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established.	Assay laboratory operates to ISO 17025 and are accredited by the local regulatory authority.
Verification of sampling and assaying			· The verification of significant intersections by either independent or alternative company personnel. · The use of twinned holes. · Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. · Discuss any adjustment to assay data.	No 3^rd party verification undertaken. Tungsten (W) assays are converted to Tungstate (WO₃) using a factor of 1.261. No other adjustments are made to the assays data.
Location of data points			· Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. · Specification of the grid system used. · Quality and adequacy of topographic control.	Hand held GPS. Map Grid NAD 83 zone11.
Data spacing and distribution			· Data spacing for reporting of Exploration Results. · Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. · Whether sample compositing has been applied	Holes are spaced at less than 40m The hole spacing was adequate for indicated resource classification by independent resource consultants.
Orientation of data in relation to geological structure	· Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. · If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.			The drill orientation provides mineralised material across a broad area of the proposed mining volume which is ideal for metallurgical test work samples.
Sample security	· The measures taken to ensure sample security.			Drill samples remains in the custody of the supervising geologist and stored in a locked building.
Audits or reviews	· The results of any audits or reviews of sampling techniques and data.			None
