THOR MINING PLC

PILBARA GOLDFIELDS RAGGED RANGE PROJECT
ACQUISITION OF ADJACENT EXPLORATION TENEMENTS

 

The directors of Thor Mining Plc ("Thor" or the "Company") (AIM, ASX: THR) are pleased to advise that it has signed a non-binding Term Sheet for the acquisition of additional licence areas adjacent to Ragged Range in the Pilbara region of Western Australia.

Highlights:

·    Two additional licences (E46/1340 and E46/1354 (application) include areas over, and surrounding, historical small scale gold and copper mines.

·    Total Thor Pilbara licence area, including 73 sq kms under application, totals 213 sq kms.

·    New licence area increases the Thor exposure to potential granite contact deposits, complementing the mafic/ultra mafic contact exposure dominated by the 13 kilometre gold zone previously reported(THR:ASX 21 October 2020).

·    The newly acquired tenure is considered highly prospective for shear hosted gold mineralization along the granite contacts to the north and hydrothermal copper mineralization associated with the felsic porphyries intruding the mafic Euro Basalts in the north- east.

·    Anomalous historic stream sediments include up to 76ppb gold with 240ppm copper (Sample 2430)1 

·    Data review over the newly acquired ground continuing, with field programs planned for early 2021.

·    Airborne magnetics data has been received with magnetic interpretation in progress.

·    Stream sediment samples from the October field program are still at the laboratory with results now anticipated early December.

Mick Billing, Executive Chairman of Thor Mining, commented:

"We are delighted to be able to add to our holdings adjacent to Ragged Range where we have made very encouraging progress this year."

"The eastern portion of the newly acquired area hosts sites of historical small scale gold and copper mining, however there has been very little modern day exploration of this area."

"We expect shortly to have assays from the October sampling program where we also recovered visible gold via panning, and are also working on interpretation of the data from the recently completed airborne magnetic survey, which is aimed at refining gold and nickel drill program planning."

1.1        Section 1 Sampling Techniques and Data

 

 

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.

The historic program comprised stream sediment trap site sampling for geochemical analysis for Au 2.5kg BLEG (-20mesh/850um), and B/AAS for Cu, Pb, Zn, Ag, Sb, As, Ni, & Mn.  Bulk cyanide Leach with DIBK and graphite furnace finish for Au & Pb to 0.1ppb 

 

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).

Not applicable

 

Drill sample recovery

·    Method of recording and assessing core and chip sample recoveries and results assessed.

·    Measures taken to maximise sample recovery andensure 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.

and sample preparation

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.

 

 

 

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.

The assay method is appropriate for preliminary exploration.

 

All samples were prepared and analysed by independent laboratory Genalysis in Perth, WA.

 

Samples were analysed for the following:

1.   mix and split off 250grams for drying and pulverised to 75microns.

2.   Digestion and analysis for Cu, Pb, Zn, Ag, Sb, As, Ni, & Mn using B/AAS sample method. 

3.   Remaining 2.25 sample was Bulk cyanide Leached with DIBK and graphite furnace finish for Au & Pb to 0.1ppb 

 

Pre-prepared 2kg BLEG standards were submitted every 30-50 samples for quality control

 

 

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.

Not undertaken

·    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.

Not applicable - no resource is being reported

 

 

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.

Orientational bias is not applicable to stream sediment sampling which are essentially one dimensional.

 

 

Sample security

·    The measures taken to ensure sample security.

Samples submitted to Intertek Genalysis Perth, WA for analysis.

Sample security appropriate for preliminary reconnaissance assessment.

 

Audits or reviews

·    The results of any audits or reviews of sampling techniques and data.

easting and northing of the drill hole collar

elevation or RL (Reduced Level - elevation above sea level in metres) of the drill hole collar

dip and azimuth of the hole

down hole length and interception depth

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.

No drilling has been undertaken or reported

Data aggregate n 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 metalequivalent values should be clearly stated

Only field observations have been reported. There has been no data aggregation.

Relationship between mineralisaton 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').

No drilling has been undertaken or reported

 

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.

Data included in report

 

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.

All results have been reported

 

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.

All data have been reported

 

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.

It is anticipated that further stream sediment geochemistry and geological mapping will be undertaken to locate the source of any mineralisation.
