Report for December Quarter 2019

MINERAL EXPLORATION

LAKE TORRENS PROJECT, SOUTH AUSTRALIA

Pernatty Project - EL 6137 (Tasman 100%)

The Pernatty Project is located approximately 20km SSE of the IOCG deposit at Carrapateena, within Exploration Licence 6137 (refer Figure 1). The area was initially targeted by Tasman for its potential to host IOCG deposits due to available geophysical data, the possibility of reasonable basement depths and its proximity to Carrapateena. Importantly, Tasman’s regional geological studies identified Pernatty as lying within an interpreted prospective “corridor” containing the most commercially favourable IOCG deposits at Olympic Dam, Wirrda and the three deposits in the Carrapateena area (see Figure 1). Recently, BHP has announced the potential discovery of a major new deposit at Oak Dam West, which is also located within this interpreted corridor. There has been no previous drilling within the tenement .

Electromagnetic (EM) Survey Results

EM surveying over priority gravity and magnetic targets (refer ASX announcement 7 January 2019) identified within the Pernatty IOCG project, was completed, including follow up surveys, in December last year. A total of 54.7 line kms were surveyed over the two target areas (refer Figures 1&2). The aim of the survey was to locate anomalous areas of electrical conductivity in the basement that could be due to IOCG associated copper sulphide mineralisation, as well as give information about depth to basement.

Geophysical modelling of the EM data in conjunction with the available gravity and magnetic data has recently been completed by Tasman’s consultant geophysicist.

Report for December Quarter 2019

Southern Area

Geophysical modelling has highlighted an EM conductor in the southern area coincident with a gravity and magnetic anomaly (Figures 2 and 3) bounded by interpreted N and NE trending lineaments (Figure 3). Although all components of the coincident magnetic-gravity-conductivity anomaly are weak, the modelling suggests that elevated concentrations of sulphides may occur between about 250 and 500m depth.

Conductivity depth images (CDI’s, Figure 4a) suggest that conductive rocks occur at around 300m and are separate from shallow highly conductive material, probably saline aquifers, in the cover. The EM conductor is shown as Plate 07 in the TEM model (Figure 4b). Modelled dimensions are around 800m long and 700m wide, similar to that of the gravity anomaly. The gravity and magnetic components of the coincident anomaly are interpreted to represent felsic rocks with about 5% dense non-magnetic minerals such as hematite and sulphides with less than 0.1% magnetite. The data suggests that it is not likely to be an iron rich IOCG system, however the intersecting deeply-weathered regional lineaments suggest a possible zone of dilation, giving it a potentially interesting address.

Report for December Quarter 2019

Northern Area

Two steeply dipping conductive sheets (Figures 2, 5 a&b) have been interpreted on the southern most line in the northern area. Their high conductances suggest that they might represent sulphides in steeply dipping faults or fractures, presumably within the cover rocks, however graphite as a source of the conductivity cannot be ruled out. The top centre of Plate 1 in the model is at (751010E, 6523250N) at 53m depth and is very close to vertical. The top of Plate 2 in the model is at (751540E, 6523250N) and 103 metres depth. While these TEM anomalies appear on either flank of a north-south gravity high there are no gravity data points within 200m of this southernmost TEM line. The gravity high is inferred by interpolation.

Report for December Quarter 2019

Two small coincident magnetic -gravity -TEM highs have also been identified in the northern area at approx. 370 and 400m depth:

Body 1

Just enough of this feature is seen at the north end of north-south TEM line 751400E to permit construction of a plate-in-host TEM model whose profiles and CDI response, shown in Figure 6a&b, suggest that the maximum conductivity occurs at about 370m depth (Plate 01). This is associated with weak but coincident magnetic (2 nT) and gravity (0.2 mGal) highs. Modelling suggests less than 0.1% magnetite and 15% of a dense non-magnetic component such as hematite and sulphides. Due to the associated electrical conductivity the 15 percent estimate for the hematite and sulphide component may represent more sulphides than hematite.

Body 2

A residual gravity high at (752000E, 6524000N) coincides with a residual magnetic high, and both anomalies occur barely 150m west of a conductivity anomaly seen in the eastern end of the CDI for line 6524000N (Figure 7). The residual magnetic and gravity high can be simulated using a body with the properties of felsic rock with 5.5% percent hematite and sulphides and less than 1% magnetite.

Report for December Quarter 2019

Follow up Work

A number of drill holes are proposed to test the coincident gravity-magnetic-EM anomalies in both areas and the steeply dipping conductors in the northern area for any economic sulphide accumulations at depth. Although none of the conductors identified can be readily attributed to classic IOCG mineralization due to their relatively low gravity modelled iron contents they still have the potential to host economic copper sulphide mineralization in the cover rocks and/or basement. The applicable mineralisation models for the Pernatty anomalies are however uncertain at this stage.

The eastern Gawler Craton is a significant copper province and economic copper mineralization occurs in cover rocks at Mt Gunson, 40km to the west and in the basement at the Carrapateena IOCG deposit 20km to the northwest. As there has been no drilling in the area the local depth to basement is unknown, and the conductivity contrast between the cover rocks and basement is insufficient to determine a clear interface in the CDIs.

Vulcan, Vulcan West and Titan Projects – EL 6416 (Tasman 100%, Fortescue earning 51%).

Fortescue Agreement

Tasman Resources Ltd (“Tasman”) and FMG Resources Pty Ltd, a subsidiary of Fortescue Metals Group Ltd (ASX:FMG “Fortescue”) executed a Farm-in and Joint Venture Agreement (“Agreement”) over Tasman’s wholly owned Exploration Licence 6416 in June 2019 (Refer to TAS:ASX Announcement 14 June 2019).

EL6416 hosts the Vulcan, Vulcan West and Titan iron oxide-copper-gold (“IOCG”) prospects, approximately 30km north of BHP’s Olympic Dam mine in South Australia

Work Carried Out During the Quarter by Fortescue

Summary

During the quarter Fortescue has focused on the preparation, planning and engagement of a contractor for a detailed ground gravity survey. In addition, re-logging of drill core from the Titan Prospect continued. Three Vulcan holes have been processed through the HyLogger at the State Government drill core storage facility.

Historical Exploration Data Review

Review of historic exploration activities continued during the quarter including evaluation of drilling, geochemical, and geophysical data. Ten drill holes from the Titan Prospect have been logged. Preparation of drill core from Vulcan prospect for re-logging and HyLogger scanning is nearing completion.

Geophysics

A detailed ground gravity survey commenced on 1st December. The survey is expected to include approximately 19,000 gravity stations, comprising full-tenement gravity coverage of 400m x 400m, 200m x 200m spacing over areas of interest, through to high resolution 100m x 100m spacing over selected areas.

Report for December Quarter 2019

Drill Sample Assays

Fortescue has commenced planning of a geochemical vectoring program aimed at developing a methodology for quantifying the relative abundances and distribution of magnetite and hematite throughout the Vulcan IOCG mineral system. A representative suite of drill core samples sourced from previously crushed material will be submitted for analysis in Q1 2020 comprising FTIR, SatMagan, DTR, XRF and QXRD methods. This dataset will then be incorporated into a machine learning environment to validate the use of FTIR and/or SatMagan techniques as rapid and costeffective vectoring methods moving forward. The samples will also be scanned using the HyLogger and analysed for fluorine, which is a useful pathfinder element for IOCG systems.

Spectral Analysis

During the period, the Geological Survey of South Australia completed HyLogger spectral scanning of drill holes VUD001, VUD009 and VUD015. These holes were selected to provide a cross-section of the northern limb of the Vulcan prospect. The spectral analysis will provide additional detail on the range of alteration and mineralization as well as high resolution imagery. The results and report from these scans are expected in Q1 2020.

Program for the March Quarter

Work planned by Fortescue for the next quarter includes:

  • Continued review, re-logging and data collation of Titan and Vulcan drill core

  • Commence selected re-assaying of Titan and Vulcan drill core where necessary

  • Analysis of samples for hematite/magnetite geochemical vectoring program

  • On ground reconnaissance for future access preparation

  • Completion of ground gravity survey

  • Commencement of geophysical modelling and preliminary target generation.

Report for December Quarter 2019

Background on Vulcan and Vulcan West

(Note: All information provided in this section has been previously announced to the ASX by Tasman.)

Vulcan is located 30km NNE of the giant Olympic Dam IOCG deposit and is a very large IOCG system, where drilling to date has intersected a number of very thick intervals of alteration and low-grade mineralisation over a large target area (about 12km[2] ).

Vulcan West occupies a very geophysically anomalous and interesting zone (around 50km[2] ) between, Vulcan and Titan, another very large IOCG system within Tasman’s Exploration Licence 5499 (see Figure 8). Other regional IOCG targets within Tasman’s EL6416 are also shown in Figure 8.

As previously reported (see Tasman’s ASX Quarterly Report for the quarter ending 31 March 2018) the infill gravity survey completed in January 2018 over a previously undrilled section of the Exploration Licence, provided high quality data to enable detailed geophysical modelling (combined gravity and magnetics) over an area considered prospective for discovery of IOCG deposits. A number of potential drill targets were identified in this modelling, and as suspected, a number of these targets are at shallower depth than the nearby large Vulcan IOCG system.

Regional MT surveys conducted by the University of Adelaide have suggested that Vulcan and Olympic Dam share a very deep underlying zone of anomalously conductive rocks that are postulated to represent a zone of fluid migration, which was critical in the formation of these two very large IOCG systems.

Figure 2 (see Figure 1 for location) shows the residual gravity response obtained from the new geophysical processing and modelling over the main area of interest at Vulcan West and clearly highlights a number of distinctive anomalies. Combined modelling of this gravity data with existing magnetics has defined a number of potential drill targets at a variety of depths (Figure 2):

  • Target A: Modelled depth of about 650m

  • Target B: Modelled depth of about 700m

  • Target C: Modelled depth of about 680m

  • Target D: Modelled depth of about 850m

  • Target E: Modelled depth of about 700m

  • Target F: Modelled depth of about 750m

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.

Exploration Licence No 6137 is located
approximately 80km ESE of Woomera in
South Australia and is owned 100% by
Tasman Resources Ltd.
There are no joint ventures, partnerships or
royalties involved. The EL is covered by the
Kokatha Native Title Claim Settlement ILUA
S12014/011 and agreements between the
claimants and Tasman designed to protect
Aboriginal heritage sites. There are no
historical or wilderness sites or national
parks or known environmental settings.

Tasman has secure tenure over the EL at
the time of reporting and there are no known
impediments to obtaining a licence to
operate in the area.
Exploration done
by other parties.

Acknowledgment and appraisal of
exploration by other parties.

Very little previous exploration has been
carried out within the tenement area. This
work appears to have been confined to
government gravity and magnetic surveys
and some limited infill gravity surveying by a
previous explorer.
Geology.
Deposit type, geological setting and style of
mineralisation.

The type of deposit sought is an iron-oxide,
copper gold type system (IOCG), similar to
the Carrapateena deposit, about 20km to the
NW. Carrapateena occurs within basement
rocks beneath approximately 400m of
younger, flat-lying sedimentary cover rocks.
No drilling has been completed within
Tasman’s EL6137 and hence subsurface
geology and depth to older basement in the
tenement are uncertainat this stage.

Report for December Quarter 2019

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.

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. ‘downhole length,
true width not known’).

Diagrams.
Where possible, maps and sections (with
scales) and tabulations of intercepts should
be included for any material discovery being
reported if such diagrams significantly
clarify the report.

Appropriate geophysical maps are included
in the 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.

Not Applicable (NA) – no drilling or sampling
is 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.

Geophysical results are reported in the
report.
No other substantive exploration data is
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

The nature of planned further work is
included in the report.

Please refer to information in the report.
