SUMMARY
Impact Minerals Limited (ASX:IPT) is pleased to announce three significant developments on
Exploration Licence E7390, part of the Broken Hill Project in New South Wales:
1. An extremely high grade intercept of platinum group metals, gold, copper, nickel and silver
from Hole RHD012, high grade assays of the same metals from RHD008 and a significant
gold-copper intercept from RHD007 (see also Tables 1 and 2).
2. Impact to acquire E7390 from Golden Cross Resources Limited for $60,000 cash and a
1% gross production royalty to take Impact to 100% of the nickel-copper-PGE rights,
previously in joint venture with Golden Cross. At its election, Impact has the right to buy
back the royalty for $1.5 million cash at anytime up to a Decision to Mine, or, leave the
royalty uncapped during production.
In addition Impact will assume Golden Cross’s joint venture rights for lead-zinc-silver-other
metals with Silver City Minerals Limited and, in a related transaction;
3. Impact to move to an 80-20 joint venture with Silver City Minerals on the lead-zinc-silverother metal rights for a payment of $50,000 cash and for Silver City’s 20% interest to be freecarried to a Decision to Mine.
The mineralised intercepts discovered thus far occur in a north-south trending corridor,
sub-parallel to the general trend of the drill holes. Accordingly the optimal orientation for drilling
has not yet been established and the drill programme has been placed on hold for about a week
pending detailed studies to more fully understand the controls on the mineralisation.
In addition down hole EM surveys have identified a compelling conductor within 15 metres of the
mineralised intercept in RHD012 and an interpretation is in progress to accurately locate its
position. This will also be a drill target.
The drill programme will also test a strong EM conductor that is prospective for lead-zinc-silver
mineralisation (Target T2).
Impact Minerals’ Managing Director Dr Mike Jones said, ‘This is an outstanding outcome for Impact’s
shareholders. The Red Hill Project continues to deliver exceptional drill results and we have also now
been able to greatly simplify the previous complex metal rights ownership that we inherited when
acquiring this project only two and a half years ago”.
“Also, considering that this is only the second prospect, together with Platinum Springs, in the entire
35 km trend of the project to have been drilled to any significant degree and that both have delivered
very high grade nickel-copper-PGE assays, is testament to the exploration potential of our project” he
said.
“The challenge now is to understand the controls on this mineralisation and look to extend the zone of
interest along trend and at depth below 50 metres. We look forward to re-starting drilling as soon as
possible.”
1. Extremely High Grade Drill Intercept in RHD012
Hole RHD012 has returned:
3.5 metres at 5 g/t platinum, 6 g/t gold, 144 g/t (4.6 ounces) palladium,
2.9% nickel, 2.3% copper and 14.5 g/t silver from 67.3 metres down-hole including:
1.2 metres at 10.4 g/t platinum, 10.9 g/t gold, 294 g/t (9.5 ounces) palladium,
7.4% nickel, 1.8% copper and 19 g/t silver from 68.5 m and also including
0.5 metres at 5.1 g/t platinum, 6.6 g/t gold, 141 g/t (4.6 ounces) palladium,
1.3% nickel, 10.4% copper and 82 g/t silver from 68.0 metres down hole.
All samples were assayed at the Intertek laboratory in Adelaide. The palladium-platinum-gold
assays, including repeat assays, were done by the fire assay with lead collection technique.
All QA/QC is within tolerance and done to JORC standard for Exploration Results.
The sample pulps have been sent to the Intertek laboratory in Perth for repeat fire assays using a
nickel sulphide collection method. This assay technique will also return assays for the rare PGM’s
rhodium, osmium, iridium and ruthenium.
Figure 1. Cross section through the Red Hill Prospect.
About the mineralisation
The mineralised intercept comprises a 1.2 metre thick unit (approximately true width) of matrix to
locally massive copper and nickel sulphides within a 3.5 metre thick zone of variable disseminated
and vein-hosted nickel and copper mineralisation at about 50 metres below surface. The
photograph on page 1 shows about 40 cm of the matrix to massive sulphide unit.
The zone is interpreted as the down dip extension of the Upper Zone of mineralisation, one of two
zones of mineralisation intersected in Holes RHD001 and 006 beneath the Red Hill Mine (Figure 1).
The Lower Zone was not been intersected in Hole RHD012.
In addition the orientation of the mineralised intercepts at Red Hill has yet to be established.
Results to date suggest that the overall trend of the mineralisation at Red Hill is north-south (Figure
2). Accordingly some of the drill holes may not have been optimally oriented to intersect the
mineralisation and the true widths of many of the intercepts (except Hole RHD012) are likely to be
thinner than the down hole thicknesses.
Figure 2. Drill hole location plan for Red Hill (see also Table 2 for drill hole details).
Down hole EM Survey identifies moderate conductor close to RHD012
A down hole EM survey of Hole RHD012 showed that the matrix sulphide mineralisation was
weakly to moderately conductive, in accordance with both the style of sulphide mineralisation and
its width. In addition the survey also identified a second moderate EM conductor of small to modest
size about 15 metres off hole and about 50 metres below surface (Figure 1).
Hole RHD017 was drilled to test this anomaly and intersected a 10 m thick zone of anomalous
weathered copper-nickel-arsenic mineralisation (as measured by a hand held XRF instrument) at
35 metres down hole. The source of the EM conductor was not found and a down hole EM survey of
RHD017 is now in progress to better determine its location. Assays from the mineralised zone are
expected within three to four weeks.
2. High grade Drill Intercept in RHD08
RHD008 was drilled to test the surface projection of the Upper and Lower Zones of mineralisation
found in Holes RHD001 and 006 (Figure 1). The hole was drilled sub-parallel to the mineralisation
because of steep terrain west of the Red Hill Mine Shaft. The true width of the zone is not known.
The hole returned:
29 metres at 2.7 g/t platinum, 0.5 g/t gold, 5.5 g/t palladium,
0.5% nickel, 2.4% copper and 57.8 g/t silver from surface.
The mineralisation is associated with variable copper and nickel oxide and sulphide minerals. It is
interpreted that the mineralisation is mostly within the Lower Zone of mineralisation and that the
dormant Red Hill shaft was sunk predominantly on the Upper Zone of mineralisation (Figure 1).
These results confirm that high grade mineralisation at Red Hill extends to surface. All mineralised
intercepts at Red Hill are within 50 metres to 60 metres from surface and are open at depth and to
the south.
3. Gold Intercept in RHD007
Hole RHD007 was drilled to test the depth extent of the southern part of the Red Hill Intrusion
(Figures 2 and 3). The hole intersected variable types of ultramafic rock with weak copper and
nickel mineralisation in places.
The lower contact of the ultramafic unit with underlying metasedimentary rocks was intersected at
346.5 metres down hole. A second thinner ultramafic unit 18 m thick was intersected at 357 metres
down hole.
A significant assay was returned of:
5 metres at 0.6 g/t gold, 0.1% copper, 25 parts per billion (ppb) palladium and
15 ppb platinum from 364 metres and including
2 metres at 1.8 g/t gold and 0.1% copper from 365 metres down hole.
The lower most part of the main ultramafic unit also contains anomalous copper and returned:
10 metres at 700 ppm copper from 332 metres down hole.
A down hole EM survey of RHD007 has identified an off-hole conductor of limited size extent offhole at about 350 metres down hole and close to the lower contact of the main ultramafic unit. This
contact is prospective for massive sulphides. Detailed modelling of the EM conductor is in progress.
All of these results are very encouraging for further exploration along the basal contact of the
ultramafic unit.

5. Purchase of E7390 from Golden Cross Resources Limited
Impact and Golden Cross Resources have signed a binding term sheet for Impact (via its 100%
owned subsidiary Siouville Pty Limited) to acquire E7390 to take Impact to 100% of the
nickel-copper-PGE rights, previously in joint venture with Golden Cross. In addition Impact will
assume Golden Cross’s joint venture rights for lead-zinc-silver-other metals with Silver City
Minerals.
The consideration payable to Golden Cross is $60,000 cash and a 1% gross production royalty on all
metals to which Impact and or Siouville has the rights for.
At its election Impact also has the right to buy back the royalty for $1.5 million at anytime up to a
Decision to Mine, or leave the royalty uncapped during any production.
The transaction is now only subject to Ministerial approval, which is expected within two months.
Squadron Resources Pty Limited has the right to invest $1 million for a 19.9% interest in the
nickel-copper-PGE rights under the terms of an investment into Impact as outlined in the
announcement to the ASX dated 17 July 2015. However, Squadron is not liable for any payment of
the royalty to Golden Cross.
6. Impact to acquire 80% of the Lead-Zinc-Silver-Other Metals Rights
Impact and Silver City Minerals Limited have signed a binding term sheet for Impact (also via its
100% owned subsidiary Siouville Pty Limited) to form a joint venture for exploration for
lead-zinc-silver-other metals. Impact will own 80% of the rights to those metals and will free-carry
Silver City’s 20% interest to a Decision to Mine.
The consideration payable to Silver City is $50,000 cash.
The agreement with Silver City will come into force upon the Ministerial approval of the transfer of
E7390 to Impact.
Squadron Resources Pty Limited has no rights to earn into the lead-zinc-silver-other metals rights.
7. Next Steps
Detailed core logging and a synthesis and interpretation of all the geological, assay and geophysical
data collected is in progress together with a down hole EM survey on RHD017.
Drilling will recommence next week and will first test a significant EM anomaly at Target T2. The
anomaly occurs down dip of outcrops of Broken Hill style mineralisation (lode rocks) and is
considered a compelling drill target (Figure 3).
Further drill holes at Red Hill will be designed as the interpretation progresses. However new
environmental permits for follow up drill holes will be required in places and these may take up to a
further 30 days to be granted.

Dr Michael G Jones
Managing Director
The review of exploration activities and results contained in this report is based on information compiled by Dr Mike Jones, a
Member of the Australian Institute of Geoscientists. He is a director of the company and works for Impact Minerals Limited. He has
sufficient experience which is relevant to the style of mineralisation and types of deposits under consideration and to the activity
which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the Australasian Code for Reporting of
Exploration Results, Mineral Resources and Ore Reserves (the JORC Code). Mike Jones has consented to the inclusion in the report of
the matters based on his information in the form and context in which it appears.
APPENDIX 1 - SECTION 1 SAMPLING TECHNIQUES AND DATA
Criteria
JORC Code explanation
Commentary
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.
Rock Chip Samples
Random rock samples were taken at surface which represented favourable geology and alteration to
known mineralisation in the region. Samples are variably weathered.
Soil Samples
Soil samples were taken at 50 m intervals from a hole 15-20 deep and sieved to -2mm to collect about
250 g of material.
Diamond Drilling
Diamond drilling was used to produce drill core either with a diameter of 63.5 mm (HQ) or 47.6 mm (NQ).
A handheld XRF instrument was used to analyse the drill core at 50 cm intervals.
Include reference to measures taken to ensure sample representivity and
the appropriate calibration of any measurement tools or systems used
Rock Chip Samples
Representative rock chip samples at each sample site weigh between 0.8 and 1.2 kg. Soil samples are
taken at a consistent depth below surface and sieved.
Soil Samples and Drill Samples
Sample representivity was ensured by a combination of Company Procedures regarding quality control
(QC) and quality assurance / testing (QA).
Examples of QC include (but are not limited to), daily workplace and equipment inspections, as well as
drilling and sampling procedures.
Examples of QA include (but are not limited to) collection of “field duplicates”, the use of certified
standards and blank samples approximately every 50 samples.
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
Rock Chip and Diamond Drill Samples
Rock samples and split diamond core were sent to Intertek Adelaide where they were crushed, dried and
pulverised (total prep) to produce a 25-30 g sub-sample for analysis by four acid digest with an ICP/AES
finish for ore grade base metal samples and either lead collection or nickel sulphide fire assay with AAS or
MS finish for gold and the PGMs. Weathered samples contained gossanous sulphide material. Soil
samples were sent to SGS Perth for analysis by the MMI digest.
The XRF data is qualitative only. A comparison between the XRF results and wet chemical assay data will
be completed on receipt of final results.
Sampling techniques
Drilling techniques
Drill sample recovery
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).
Method of recording and assessing core and chip sample recoveries and
results assessed
Diamond Drilling comprises NQ (47.6 mm diameter) and HQ (63.5 mm diameter) sized core. Impact
diamond core is triple tube and is oriented. Historical diamond core was not oriented.
Diamond core recoveries for all holes are logged and recorded. Recoveries are estimated to be
approximately >97% for the Red Hill Prospect. No significant core loss or sample recovery problems are
observed in the drill core.
Criteria
JORC Code explanation
Commentary
Measures taken to maximise sample recovery and ensure representative
nature of the samples
Diamond core is reconstructed into continuous runs on an angle iron cradle for orientation marking.
Depths are checked against the depth given on the core blocks and rod counts are routinely carried out
by the driller.
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 sample bias has been established.
Logging
Geological logging of samples followed company and industry common practice. Qualitative logging of
samples included (but not limited to); lithology, mineralogy, alteration, veining and weathering. Diamond
core logging included additional fields such as structure and geotechnical parameters.
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.
Magnetic Susceptibility measurements were taken for each 0.5 m diamond core interval.
For diamond core, information on structure type, dip, dip direction, texture, shape and fill material has
been recorded in the logs. RQD data has been recorded on selected diamond holes. Handheld XRF
analysis was completed at 50 cm intervals on diamond core.
Whether logging is qualitative or quantitative in nature. Core (or costean,
channel, etc) photography.
All logging is quantitative, based on visual field estimates. Systematic photography of the diamond core in
the wet and dry form was completed.
All diamond drill holes were logged in full.
The total length and percentage of the relevant intersections logged
Sub-sampling techniques and
sample preparation
Detailed diamond core logging, with digital capture was conducted for 100% of the core by Impact’s onsite geologist.
If core, whether cut or sawn and whether quarter, half or all core taken.
All core samples were sampled by half core. Selected intervals of quarter core will be selected for check
assays if required.
If non-core, whether riffled, tube sampled, rotary split, etc and whether
sampled wet or dry.
No RC drilling results are reported.
For all sample types, the nature, quality and appropriateness of the sample
preparation technique.
Company procedures were followed to ensure sub-sampling adequacy and consistency. These included
(but were not limited to) daily work place inspections of sampling equipment and practices, as well as
sub-sample duplicates (“field duplicates”).
Quality control procedures adopted for all sub-sampling stages to maximise
representivity of samples.
Laboratory QC procedures for rock sample and diamond drill core assays involve the use of internal
certified reference material as assay standards, along with blanks, duplicates and replicates.
Measures taken to ensure that the sampling is representative of the in situ
material collected, including for instance results for field duplicate/secondhalf sampling.
Rock and Soil Samples
Field duplicates were taken at selected sample sites.

Diamond Core Samples
Quarter core duplicate samples are taken randomly every 50 samples. Sample sizes at Red Hill are
considered adequate due to mineralisation style.
The nature, quality and appropriateness of the assaying and laboratory
procedures used and whether the technique is considered partial or total.
An industry standard fire assay technique for samples using lead collection with an Atomic Absorption
Spectrometry (AAS) finish was used for gold and aqua regia digest for base metals and silver.
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.
No geophysical tools were used to determine material element concentrations. A handheld XRF was used
for qualitative analysis only.
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.
Rock Chip Samples
For the rock chips, quality control procedures for assays were followed via internal laboratory protocols.
Accuracy and precision are within acceptable limits.
Diamond Drill Samples
Reference standards and blanks are routinely inserted into every batch of samples at a rate of 1 in every
50 samples.
The verification of significant intersections by either independent or
alternative company personnel.
The results have not been verified by independent or alternative companies. This is not required at this
stage of exploration.
The use of twinned holes.
No drilling results are reported.
Documentation of primary data, data entry procedures, data verification,
data storage (physical and electronic) protocols.
Primary assay data for rock chips has been entered into standard Excel templates for plotting in Mapinfo.
All historical drill data has been entered digitally by previous explorers and verified internally by Impact.
Discuss any adjustment to assay data.
There are no adjustments to the assay data.
Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral
Resource estimation.
Sample locations and drill holes were located by hand held GPS.
Specification of the grid system used.
The grid system for Broken Hill is MGA_GDA94, Zone 54.
Quality and adequacy of topographic control.
Standard government topographic maps have been used for topographic validation.
For the diamond holes, down-hole single shot surveys were conducted by the drilling contractor. Surveys
were conducted at 15 m, 30 m and then approximately every 30 m down-hole.
Data spacing for reporting of Exploration Results.
Sample spacing for the soil survey was on a 50 m by 50 m grid.
Reconnaissance drill spacing is approximately 200 m.
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.
Estimations of grade and tonnes have not yet been made.

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.
All reported assays have been length weighted. No top cuts have been applied. A cut-off of approximately
0.1% Cu, 0.4% Cu and 1.0% Cu has been applied for reporting of exploration results.
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.
High grade massive sulphide intervals internal to broader zones of disseminated sulphide mineralisation
are reported as included intervals.
The assumptions used for any reporting of metal equivalent values should
be clearly stated.
No metal equivalents have been 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 (e.g. ‘down hole length, true width not
known’).
