20150323 Latest results confirm high-grade copper-nickel-PGE potenial at Stark FINAL
ASX Release - 23 March 2015
Latest results confirm high-grade copper-nickel-PGE potential at Stark
Drill results from recent Diamond drill program extend copper-nickel-PGE mineralised zone and confirm Stark's high-grade potential, including (downhole widths):
o 16.37m @ 0.40% copper, 0.07% nickel, and 0.20g/t (gold + platinum + palladium - "PGE's")
including; 0.27m @ 0.41% copper, 1.62% nickel, and 1.60g/t PGE's and
0.43m @ 2.19% copper, 0.12% nickel, and 0.77g/t PGE's
o 0.15m @ 13.70% copper, 0.16% nickel, 3.94g/t PGE's, and 73.7g/t silver
New intercepts lie approximately 40 and 80 metres down dip respectively of two previous drill intercepts: 4m @ 1.91% copper, 0.18% nickel, and 0.96g/t PGE's, and 2m @ 1.04% copper, 0.18% nickel, and 0.49g/t PGE's
Copper-nickel-PGE mineralisation lies on basal contact of mafic intrusion with potential new
"hanging wall" nickel zone identified
Mineralisation intersected over 1 kilometre strike and remains open in all directions
High-powered ground and downhole EM to define next round of drill targets commencing shortly
Mithril Resources Ltd (ASX: MTH) is pleased to advise that recently completed Diamond drilling at the Stark prospect (located 80 kilometres south east of Meekatharra, WA - Figures 1 and 2) has extended the zone of copper-nickel-PGE mineralisation, and confirmed the prospect's high-grade potential, with a number of strong assay results returned including (downhole widths);
16.37m @ 0.40% copper, 0.07% nickel, and 0.20g/t (gold + platinum + palladium - "PGE's") from 213.43 metres in NDD15001, including; 0.27m @ 0.41% copper, 1.62% nickel, and 1.60g/t PGE's from 213.43 metres and 0.43m @ 2.19% copper, 0.12% nickel, and 0.77g/t PGE's from 213.70 metres,
0.6m @ 3.81% copper, 0.05% nickel, 1.05g/t PGE's, and 19.1g/t silver from 246.35 metres in NDD15001, including; 0.15m @ 13.70% copper, 0.16% nickel, 3.94g/t PGE's, and 73.7g/t silver from 246.35 metres.
The latest intercepts were returned from disseminated and massive sulphides (pyrrhotite-chalcopyrite- pentlandite-pyrite) that occur both within, and at the base of a mafic (gabbro) intrusion adjacent to a Banded Iron Formation (BIF) and metasedimentary sequence (Figure 3). The drilling also intersected disseminated sulphides (chalcopyrite) within the metasediments below the base of the intrusion (Figure 4).

As well as confirming Stark's high-grade potential, the latest intercepts suggest that mineralisation at the base of the mafic intrusion is continuous down-dip with the very high-grade copper intercept in NDD15001 (0.15m @
13.70% copper, 0.16% nickel, 3.94g/t PGE's, and 73.7g/t silver) lying 40 and 80 metres respectively, down dip of two earlier Mithril drill holes - NRC14008 (4m @ 1.91% copper, 0.18% nickel, and 0.96g/t PGE's), and NRC14003 (2m @ 1.04% copper, 0.18% nickel, and 0.49g/t PGE's)(Figure 3).
The NDD15001 intersection also occurs at the lower edge of a late stage dolerite dyke that appears to have partially "stoped out" the basal contact mineralisation in the vicinity of the drill hole, and as such, the intersection may represent the remains of a thicker zone of copper mineralisation that was present before the dyke was emplaced. This concept will be tested by further drilling in future programs.
The latest results also demonstrate the potential for multiple mineralised horizons at Stark.
The zone of nickel mineralisation in NDD15001 (from 213.43 metres) occurs above the base of the mafic intrusion and is interpreted to be a new "hanging wall" position which has not been previously intersected and remains open in all directions (Figure 3).
The new results lie within the central portion of a 500m long series of modelled EM plates at the southern end of a broader 1km long zone of bedrock copper-nickel-PGE mineralisation (Figure 5) which remains open both north and south along strike.
Throughout the 1km zone, only eight RC and Diamond holes have been drilled - all by Mithril since December last year.
Stark is rapidly emerging as a significant copper-nickel-PGE discovery and to define the next round of drill targets, a program of high-powered ground and downhole electromagnetic surveying will commence shortly. Recent heavy rainfall at Stark has delayed the arrival of the geophysics contractor.
Stark lies within the Nanadie Well Project located 80 kilometres south east of Meekatharra, WA (Figure 1) on tenements subject to a Farmin and Joint Venture Agreement with Intermin Resources Limited (ASX: IRC).
Under the terms of the joint venture, Mithril can earn a 60% interest in the project tenements by completing expenditure of $2M by 14 April 2018, and an additional 15% by completing further expenditure of $2M over a further 2 years (in total $4M over 6 years for 75% - see ASX Announcement dated 6 December 2013).

JORC Code, 2012 Edition - TABLE 1
Section 1: Sampling Techniques and Data
Criteria
|
JORC Code explanation
|
Commentary
|
Sampling techniques
|
Nature and quality of sampling (e.g. 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.
|
Diamond drilling was completed at the Stark copper-nickel-PGE
prospect.
Quarter core samples were collected on the basis of geological intervals and will typically range in length from 0.25 to 1 metre.
|
Sampling techniques
|
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
|
Each drill hole location (easting and northing) was collected by a
handheld GPS. Detailed logging of Collar, Drilling, Survey,
Lithology, Sample, and Magnetic Susceptibility information was completed for every metre, or as necessary, for each drill hole.
All logging and sampling protocols remained constant throughout the program.
|
Sampling techniques
|
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 (e.g. '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 (e.g. submarine nodules) may warrant disclosure of detailed information.
|
NQ Diamond drill core was obtained for geological logging and
sampling purposes.
Quarter core samples were collected on the basis of geological intervals and typically range in length from 0.25 to 1 metre. Samples (typically 1 - 3kg sample weights were collected for geochemical analysis by ALS Laboratories in Perth, WA.
In the laboratory, samples were crushed (~10mm) and pulverised to produce a representative 25g sub-sample for analysis using fire assay with ICP-MS finish for Au, Pt, and Pd (PGM-ICP23 - Lab Code) and four acid digest with ICP-AES finish for Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sn, Sr, Te, Ti, Tl, V, W, and Zn (ME-ICP61 - Lab Code).
|
Drilling techniques
|
Drill type (e.g. core, reverse circulation, open-hole hammer,
rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. 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.).
|
A LF90D Diamond drill rig was used to complete the program. Drill rod size was HQ followed by NQ.
|
Drill sample recovery
|
Method of recording and assessing core and chip sample
recoveries and results assessed.
|
Drill core recoveries were recorded at the time of logging.
|
Drill sample recovery
|
Measures taken to maximise sample recovery and ensure
representative nature of the samples.
|
No measures taken to maximise sample recovery.
|
Drill sample recovery
|
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.
|
No relationship has been identified.
|
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.
|
Detailed logging of Collar, Drilling, Survey, Lithology, Sample, and
Magnetic Susceptibility information was completed in each hole.
Lithology and Magnetic Susceptibility was logged for every metre intervals, and Surveys collected every 30 - 50m down hole.
|
Logging
|
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography
|
Logging of core samples is of a qualitative nature.
Drill core is logged for lithology, colour, texture, weathering, minerals, alteration, and sulphide percentage and type, with comments included as necessary. Photos of the core are taken for the entire hole. Logging is qualitative in nature.
|
Logging
|
The total length and percentage of the relevant
intersections logged.
|
Every hole was logged (Lithology and magnetic susceptibility) for
every metre (entire length of hole).
|
Sub- sampling techniques and sample preparation
|
If core, whether cut or sawn and whether quarter, half or
all core taken.
|
Diamond drill core was sawn and quarter core samples were
submitted for analysis.
|
Sub- sampling techniques and sample preparation
|
If non-core, whether riffled, tube sampled, rotary split, etc.
and whether sampled wet or dry.
|
Not applicable as only core samples are to be collected.
|
Sub- sampling techniques and sample preparation
|
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
|
The sample preparation of the Diamond drill core samples follows
industry best practice, involving oven drying (110°C) where necessary, crushing and pulverising (~90% less than 75μm).

Commentary
|
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
|
Along with the core samples, standards and blanks were inserted
(around every 50 samples) and were included in the laboratory analysis process. Standards were Certified Reference Material (from Geostats Pty Ltd) of varying grades of Cu and Ni, and blanks were coarse sand.
|
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.
|
For each quarter core sample submitted for analysis, the remaining drill core sample has been retained for future analysis if warranted. Drill core was also photographed prior to sampling.
|
Whether sample sizes are appropriate to the grain size of the material being sampled
|
Sample sizes are considered appropriate for the exploration
method and produce results to indicate degree and extent of
mineralisation.
|
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.
|
Fire Assay and a four acid digest are considered near total digest and are appropriate for the type of exploration undertaken.
|
Quality of assay data and laboratory tests

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.
|
A handheld XRF instrument (NITON) was used in the field to assist with identifying anomalous base metal zones. Magnetic susceptibility readings were also taken of each sample.
|
Quality of assay data and laboratory tests
|
Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.
|
The laboratory will complete repeats analysis on samples
returning >10000 ppm Cu and Ni, >5% S, and >20% Mg. Routine (around 1 in 30) repeats and regular blanks and standards analysed throughout. From results achieved it is determined an acceptable level of accuracy and precision has been established.

|
The verification of significant intersections by either
independent or alternative company personnel.
|
Results included within were verified by the Company's Geology
Manager and Managing Director.
|
Verification of sampling and assaying
|
The use of twinned holes.
|
While no twin holes were drilled, the new Diamond drill holes
described in this report were drilled down dip and along strike
from existing mineralised RC drill holes.
|
Verification of sampling and assaying
|
Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.
|
Collar locations were predetermined in the office and modified in
the field as necessary (dependent on access etc.). All data
collection (lithology logging, sampling, etc.) was completed at each drill hole location as hole was being drilled. Data initially written on paper log sheets. A complete data set (excel spreadsheet) will be created by Mithril on completion of the program, based on all information collected. Following verification, all data will be included in an Access Database.

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 work described in this Report was undertaken on Exploration Licence 51/1040 which is owned by Intermin Resources and in which, Mithril has the right to earn up to a
75% interest by completing $4M expenditure over 6 years
(See ASX Announcement dated 6 December 2013).
|
Mineral tenement and land tenure status
|
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.
|
There are no existing impediments to the tenements.
|
Exploration done by other parties
|
Acknowledgment and appraisal of exploration by other parties.
|
Intermin estimated a 2004 JORC Code Compliant Inferred
Resource for the Nanadie Well Copper Deposit of 36.07Mt @
0.42% Cu in September 2013.
This work followed the completion of various previous RAB, RC and geophysical surveys throughout the area by Intermin and previous exploration companies.
|
Geology
|
Deposit type, geological setting and style of mineralisation.
|
The Nanadie Well Copper Deposit and Stark prospect is interpreted to be an Archaean - age, mafic-hosted magmatic copper-nickel deposit. Disseminated copper (+/- lead, zinc, nickel) sulphide mineralisation occurs within a package of structurally deformed mafic lithologies.
|
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:
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.
|
A summary of the Diamond drilling referred to in this Announcement is presented in Tables 1 and 2 of the Report. Also see Figures within this Announcement.
|
Drill hole
Information
|
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 information has been excluded
|
Data aggregation methods
|
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.
|
Length weighted averaging of drill results was applied where an intercept contained internal intervals of varying (non- equal) lengths.
For reporting copper and nickel results, a lower cut-off grade of 0.25% has been applied. No upper cut offs have been applied. No cut-off grades have been applied to reporting of PGE's.
|
Data aggregation methods
|
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.
|
Length weighted averaging of drill results was carried out according to the following formula:
[Sum of (all individual assay values x corresponding individual sample length for selected intersection)] divided by [total length of selected intersection].

Commentary
|
The assumptions used for any reporting of metal equivalent values should be clearly stated.
|
No metal equivalents reported
|
Relationship between mineralisation widths and intercept lengths
|
These relationships are particularly important in the reporting of Exploration Results.
|
Widths of mineralisation have not been postulated. All mineralised intervals quoted in this announcement are quoted as downhole widths only.
|
Relationship between mineralisation widths and intercept lengths
|
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
|
While the geometry of the mineralisation is not known, the orientation of the drillholes in relation to the interested geology is shown in the figures in this announcement.
|
Relationship between mineralisation widths and intercept lengths
|
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. 'down hole length, true width not known').
|
The Exploration Results in this Announcement are reported as down hole widths only as true widths are not known.
|
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.
|
See Figures including in this announcement.
|
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 are 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 relevant data has been included within this Report
|
Further work
|
The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step- out drilling).
|
Further drilling and downhole EM surveying is planned as a further test of the Stark copper - nickel mineralised zone outlined in this Announcement.
