IRW-PRESS: Altona Mining Ltd.: Altona Mining Ltd.: Bedeutende Bohrziele auf Roseby South
identifiziert
BEDEUTENDE BOHRZIELE AUF ROSEBY SOUTH IDENTIFIZIERT
- Zwei neue große sehr reichhaltige Kupferanomalien im Boden mit anomalen Gehalten von bis
zu 4,6 % Kupfer auf Harvest und 5,6 % Kupfer auf Hobby.
- Beide Anomalien sind mit den Ergebnissen aus Altonas Lagerstätte Little Eva
vergleichbar.
- Gesteinssplitterproben mit bis zu 14,4 % Kupfer und 0,74 g/t Gold auf Harvest und 23,3 % Kupfer
und 2,9 g/t Gold auf Hobby.
- Das beste Ergebnis der wenigen in den 1990er-Jahren auf Harvest niedergebrachten Bohrungen war
74 m mit 0,52 % Kupfer und 0,11 g/t Gold.
- Die Bohrungen werden in den kommenden Monaten beginnen.
Altona Mining Limited (Altona oder das Unternehmen -
http://www.commodity-tv.net/c/search_adv/?v=296468) gibt bekannt, dass das Unternehmen zwei neue
große und sehr reichhaltige Kupferanomalien im Boden auf seinem sich vollständig in
Unternehmensbesitz befindlichen Projekt Roseby South (Roseby South) in der Nähe des Mt Isa in
Queensland abgegrenzt hat.
Roseby South liegt unmittelbar an der Südgrenze des Projekts Cloncurry des Unternehmens und
MMGs großer Untertagezinkmine auf Dugald River (Abbildung 5).
Das Projekt Cloncurry unterliegt einem geplanten Joint Venture im Wert von 235,5 Mio. USD (JV)
mit Sichuan Railway Investment Group (SRIG). Nähere Informationen hinsichtlich des SRIG JV
finden Sie in der Pressemitteilung vom 2. Juni 2016.
Roseby South ist eine sich zu 100 % im Besitz der Altona befindliche Explorationsliegenschaft.
Sie ist nicht Teil der Vereinbarungen mit SRIG. Das Projekt Roseby South besitzt zwei gewährte
Explorationsgenehmigungen (Exploration Permits for Minerals, EPM), die eine Fläche von
ungefähr 476 km2 abdecken (Abbildung 3).
Die Explorationstätigkeiten auf Roseby South sind der Beginn einer von Altona
durchgeführten Kampagne zur Erweiterung ihrer Explorationsaktivitäten im stratigrafischen
Fenster des Mt Isa. Mit dieser Verlagerung hin zu weiteren Explorationstätigkeiten, wurde eine
Neubewertung von Roseby South durchgeführt nach seiner Rückgabe an Altonas Management im
Jahr 2015 nach Ablauf einer Option auf das Projekt. Die Geländeprogramme begannen im April 2016
und zielten auf vererzte Korridore, die sich über die Länge der Liegenschaft des
Unternehmens erstrecken. Die Geländearbeiten konzentrierten sich auf sehr genaue
Bodenprobenentnahmen, Prospektionsarbeiten und geologische Kartierungen.
Die Anomalien Harvest und Hobby (Abbildungen 1, 2, 3 und 4) sind unter den zahlreichen
Erkundungsgebieten, die sich in einer frühen Abgrenzungsphase befinden, die am besten
definierten Ziele.
Für Harvest und Hobby wird ein RC-Bohrprogramm geplant und in Abhängigkeit des
Explorationsfortschritts wird Altona ebenfalls ein oder zwei andere Erkundungsgebiete, die zurzeit
bewertet werden, durch Bohrungen überprüfen. Verschiedene Abkommen mit dritten Parteien
und sogenannte Aboriginal Heritage Clearances sind vor dem Bohrbeginn notwendig. Dies wird laut
Erwartungen 2 bis 3 Monate in Anspruch nehmen. Eine Abbildung der Bodenanomalie auf der
Lagerstätte Little Eva (Abbildung 4) wird ebenfalls zur Verfügung gestellt, um den
Zusammenhang mit den Zielgebieten und der regionalen Analogie zu zeigen.
Altona wird den Markt über den Bohrbeginn informieren.

der Gesteinssplitterproben.
Die Ziele Harvest und Hobby zeichnen sich aus durch:
Bodenanomalien
Große und zusammenhängende Kupferanomalien im Boden mit ähnlichem Umfang und
Gehalt (+1000 ppm Kupfer) wie die Kupferanomalie auf der Lagerstätte Little Eva des Projekts
Cloncurry (546.000 Tonnen enthaltenes Kupfer und 295.000 Unzen Gold, Anhang 4). Die
Spitzenkupfergehalte innerhalb der Anomalien liegen auf Hobby bei 5,6 % und auf Harvest bei 4,6 %.
Ein betriebsinternes Verfahren, das eine schnelle und billige Analyse mittels handgeführter XRF
verwendet, war der Schlüssel zur Abgrenzung dieser Anomalien durch in sehr engen Abständen
entnommener Proben (Abbildungen 1, 2 und 4).
Anomalien in Gesteinssplitterproben
Anomale und oft hochgradige Kupfer- und Goldgehalte in Gesteinssplitterproben aus
Aufschlüssen und Lesesteinen sowohl oxidiert als auch frisch. Es wurden zum Beispiel
Spitzenwerte von 14,4 % Kupfer und 0,74 g/t Gold auf Harvest und 23,3 % Kupfer und 2,9 g/t Gold auf
Hobby gefunden. Die Analyse der Gesteinssplitter erfolgte durch herkömmliche Vefahren (Anhang
3).
Hochgradige Bohrergebnisse
Auf Hobby wurden keine Bohrungen niedergebracht.
Auf Harvest zeigen die wenigen in den 1970er-Jahren (Tabellen 2 und 3) niedergebrachten Bohrungen
das Potenzial für eine wirtschaftliche Kupfer-Gold-Vererzung. Zum Beispiel lieferte die von
Placer im Jahre 1992 (Abbildung 1) niedergebrachte Bohrung:
74 m mit 0,51 % Kupfer und 0,11 g/tGold ab Oberfläche:
Einschließlich 8 m mit 1,65 % Kupfer und 0,18 g/t Gold und
--12 m mit 0,77 % Kupfer und 0,23 g/t Gold
Günstige Gesteine
Auf Harvest und Hobby haben die geologischen Kartierungen Gesteinstypen, Alterations- und
Elementvergesellschaftungen dokumentiert, die mit signifikanten IOCG-Lagerstätten in der Region
übereinstimmen.
Große Strukturen
Die Ziele liegen innerhalb zwei großer tektonischer Korridore, die das stratigrafische
Fenster Mt Isa durchschneiden und ebenfalls die Lagerstätten innerhalb des möglichen SRIG
Joint-Venture beherbergen und Ressourcen mit 1,6 Mio. Tonnen Kupfer sowie 0,4 Mio. Unzen Gold
enthalten (Anhang 4).
Historische Abbauspuren
Auf beiden Zielen wurden zahlreiche historische Abbauspuren identifiziert von
übertägigen Schürfgräben aus den 1970er-Jahren bis zu Schächten und
Tagebaugruben aus den 1920er-Jahren bis zu den 1940er-Jahren.
Geophysik
Während die Harvest-Anomalie die typischen magnetischen Charakteristika vieler
IOCG-Lagerstätten in der Region aufweist, so liefert das neue Ziel auf Hobby keine
zugehörigen magnetischen Signale in den regionalen Daten und wurde als Folge in der
Vergangenheit übersehen. Die in der Alterationszone auf Hobby beobachteten Eisenoxidminerale
sind überwiegend von Hämatit.
Eine detailliertere Beschreibung von Roseby South und jedes der Ziele finden Sie im Anhang
(Anhang 2) zusammen mit der JORC Code Tabelle 1 (Anhang 3) zur Offenlegung der Explorationsmethodik.
Obwohl die Ziele attraktiv sind, so ist der Gehalt der Oberflächenanomalien kein
verlässlicher Richtwert für die Art irgendeiner möglicherweise zugrunde liegender
Vererzung.

APPENDIX 2: Summary of the Roseby South Project
Roseby South covers an area of 476km2 (Figures 3) and is strategically located adjacent to a
number of operating, former and proposed mines. The project comprises two granted Exploration
Permits for Minerals (EPM).
The Project covers the extension of the stratigraphy that hosts Altonas 1.65 million tonne
contained copper Cloncurry Copper Project and MMG Limiteds Dugald River mine containing 7.4 million
tonnes of zinc, 1.14 million tonnes of lead and 64 million ounces of silver immediately to the
north. Dugald River has recently commenced development and Altona recently announced a US$213.53
million Framework Agreement with SRIG which, if completed, will lead to the development of a major
new copper mine at Little Eva within the Cloncurry Project.
These two major projects are situated within a regional scale north-south structural corridor
which continues for 170 kilometres further south and through the Roseby South Project for 50
kilometres. Other deposits within this corridor include the Mt Colin copper-gold mine, the Mary
Kathleen uranium mine, which closed in 1982, and the Mt Quamby gold mine which last operated in
1992. Some 120 kilometres further south on the same structure is the high grade Tick Hill gold mine
which closed in 1995. A number of other well-known major mining operations such as the Ernest Henry
and Rocklands copper-gold mines are located to the east of the Project.
Within the project area there are numerous copper-gold occurrences and artisanal mine workings
including the Companion mine (Figure 3). The Companion mine was the focus of recent soil sampling,
geophysics and drilling by Chinalco Yunnan Copper under an earn-in option with Altona, now expired.
Companion is also located within the major structural corridor and locally associated with
north-south and northwest-southeast trending fault zones. A large mineralised system has been
identified (please refer to Altona ASX release dated 30 September 2015).
Exploration Strategy
On the return of the project to 100% Altona Management in 2015 a complete re-evaluation of the
project was undertaken. Significant unexplored targets were recognised in the mineralised structural
corridors that extend the length of the Project.
In April 2016 field programs commenced with the objective of testing the targets (Figure 3). At
the core of the program is achieving consistent close-spaced soil sampling coverage across the
target corridors. Since April some 4000 plus soil samples have been collected and analysed. A
methodology has been developed by Altona using rapid and cheap analysis for copper via a portable
hand held Niton XRF instrument. The analyses are rigorously validated with reference and umpire
samples.
Two new large high-tenor copper-in-soil anomalies have been established to date, Harvest and
Hobby (Figures 1, 2 and 3) and there are numerous other prospects at an earlier stage of
definition.
Harvest Prospect
Harvest sits within the major north-south trending structural corridor that was previously
described. The prospect coincides with a sharp relief ridge which extends for more than 2 kilometres
north-south and exhibits discontinuous outcropping copper oxide mineralisation and geobotanical
anomalism (copper bush) along the ridge.
Numerous small historic workings ranging from surface trenching in the 1970's to shafts and pits
from the 1920-40's have been mapped. The prospect had been recognised by previous explorers with
reconnaissance level work being conducted through to the mid 1990s. Past names for the prospect
include The Summit and The Slots. The last significant work was conducted by Placer in 1992 who
completed 4 shallow RC drill holes (Appendix 1, Tables 2 and 3).
Copper anomalism at Harvest is characterised by a 2 kilometre by 110 metre copper-in-soils
anomaly (Figure 1 and 4) exceeding 1000ppm copper. Internal peaks within the anomaly range up to
45,917ppm (4.59%) copper and 17,442ppm (1.74%) copper. The anomaly is similar in tenor and area to
the copper-in-soil anomaly at the Cloncurry Project's Little Eva deposit although reflects a longer
and more linear target.
The copper anomalous ridge has steep sides with relief up to 90 metres. The ridge comprises
steeply dipping quartzite mapped as the Ballarra quartzite. The copper mineralisation is
structurally controlled within the quartzite and along the contacts of the quartzite with
calc-silicate rock. Overall the mineralisation is interpreted to have a steep easterly dip.
Localised rockchip sampling across the anomaly has been undertaken, largely within pre-existing
trenches. The sampling returned values up to 14.3% copper and up to 0.74g/t gold. A full list of
rockchip results is provided in Appendix 1, Table 1.
Three diamond drill holes were drilled by Australian Copper Mines in 1971 into the southern
portion of the main anomaly; no assay data is reported for these holes although graphic logs show
mineralised copper intercepts consistent with subsequent nearby drill holes by Placer in 1992.
Placer drilled 4 RC holes in the northern portion of the main anomaly; the holes drilled parts of
the mapped copper anomaly and recorded copper and gold mineralisation over broad widths. The best
intersection from the drilling was from drillhole TSP-2, Placer 1992 (Figure 1).
74 metres at 0.51% copper and 0.11g/t gold from surface:
including 8 metres at 1.65% copper and 0.18g/t gold, and---
- 12 metres at 0.77% copper and 0.23g/t gold
Full details of the drilling are summarised in Appendix 1, Tables 2 and 3.
Hobby Prospect
Hobby sits near the intersection of two regional scale structures being the north-south structure
which hosts the Companion copper-gold prospect and the Cloncurry Project copper+/-gold deposits and
the north-east trending structure which hosts the Ivy Ann copper-gold deposit.
Hobby had been missed by previous exploration having a different visual surface expression to
typical copper anomalies of similar tenor in the region.
At Hobby a large and coherent copper-in-soil anomaly greater than 1,000ppm has been defined
(Figure 2). The extent of the greater than 1,000ppm core of the anomaly is 680 by 230 metres.
Internal peaks within the anomaly range up to 6,398ppm (0.64%) copper and 56,125ppm (5.61%) copper
with the highest results close to historic workings. The anomaly is of similar size and tenor to the
copper-in-soil anomaly at the Cloncurry Project's Little Eva deposit.
The anomaly occurs within a range of hills with relief up to 120 metres. The anomaly trends
north-west cutting across steeply dipping north-south striking calc-silicate metasedimentary rocks
dominated by pink feldspar and amphibole that form the ridges.
Two small historical surface workings on narrow high-grade copper structures some 0.2 to 1 metres
wide are located in the middle of the anomaly. Two other small gossanous outcrops with abundant
copper oxide have been mapped. Overall the copper mineralisation has a subtle surface expression
being finely disseminated within the rocks. Rockchip samples of the gossanous structures returned
values from 1.6 to 23.3% copper and 0.13 to 2.9g/t gold; while 90% of the surrounding rocks returned
values greater than 0.1% copper up to 0.7% copper. A full list of available rockchip results is
provided in Appendix 1, Table 1.
No drilling has been undertaken at the prospect to date.

APPENDIX 3: TABLE 1 OF THE JORC CODE, 2012 EDITION
The table below is a description of the assessment and reporting criteria used in reporting the
Exploration Results that reflects those presented in Table 1 of The Australasian Code for the
Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code, 2012).
Section 1: Sampling Techniques and Data
Criteria Commentary
Sampling Soil samples are surface samples (top 20cm)
technique sieved to -2mm to obtain a ~100g sample size.
s Sampling is conducted only when
dry.
Rockchip samples were collected from patchy
surface rock
subcrop or outcrops and are typically chip
samples across exposed rock faces over an
area
<1m
2 and are commonly selective targeting
mineralised or altered rock
exposures.
All rockchip and duplicate (referee) soil
analyses were analysed at ALS laboratories in
Townsville.
No new Altona drill data is reported.
For the referenced historical Placer drilling
at Whippersnapper reported sampling technique
data is limited; holes are reported as RC
with sampling at 2 metre intervals.
Drilling Not applicable, no new results presented other
technique than significant intersections from historic
s data.
For the referenced historical Placer drilling
at Whippersnapper holes are reported as RC no
other data is
provided.

Quality Soil Samples
of assay Soil samples were routinely analysed for copper
data and (and a suite of
laborator
y other elements) using a Niton XL3tGOLDD+
tests hand-held XRF instrument. Analyses are
conducted routinely under controlled
conditions in the site office.
Quality Control included: standards (certified
reference materials) from
Geostats Ltd. Standards were inserted into the
sampling sequence at 1:20 ratio and included
representative material for copper.
Whenever a bias has been detected it has been
found to
be
consistent against the reference data and
therefore no corrections have been
made
.
Umpire soil samples were submitted to ALS
laboratories in Townsville for analysis using
Trace Level method by four acid near total
digest (method code
ME-ICP61
; copper range 1 -10,000ppm) for 33 elements;
and; gold using Super Trace Level method by
aqua
regia digestion with 50g sample weight (method
code: Au-ST44;
gold range 0.1ppb - 1ppm). The umpire samples
were selected from traverses across each
anomaly; these displayed no bias and an
acceptable level of precision for the
purpose.
Rock or Drill Samples
All rock samples were analysed at ALS
laboratories in Townsville for
a standard suite of elements.
Samples were analysed by Aqua Regia or a four
acid digest
(
HF-HNO3 -HClO4 acid digestion, HCl leach) diges
t using ICP-AES and ICP-MS (method code:
ME-MS41 or
ME-MS61
; copper range 0.2 - 10,000ppm)) for 51
elements. This included
copper
, with a detection limit of 0.2ppm. Data
reported from Aqua
Regia digestion should be considered as
representing only the leachable portion of a
particular
analyte while the four acid digestion is a
near-total
digestion.
On return of copper values of greater than 1%
a second series of analyses were undertaken.
This involved an ore grade Aqua
Regia digestion (method code: ASY-AR01)
followed by ICP-AES analysis optimised for
accuracy and precision at high concentrations
(method code:
ME-OG46).
Gold was analysed via a fire assay (30g) with
an AAS finish, with a lower
detecti
on limit of 0.01ppm and upper detection limit
of
100
ppm.
Quality Control utilised certified reference ma
terial
(standards) from Geostats Ltd. Standards were
inserted into the sampling sequence at
a 1:20 ratio and included representative standa
rds
for copper and gold and also blanks. Field
duplicates
were taken using a riffle splitter on site for
every
20
th sample. The laboratory also utilised
standards
which
were inserted into each sample batch.
All duplicate and reference data display
acceptable accuracy and precision.
No samples were analysed by an umpire
laboratory.
No geophysical tools were used to determine
the results reported
here.
Referenced Historical Drill Sampling
For the referenced 1992 Placer drilling at
Whippersnapper analyses are reported as
having been analysed at ALS Mount Isa using
method IC581 for 8 elements including copper,
and method PM209 for
gold.
VerificatiResults were checked by several Altona
on of personnel.
sampling
and No twinned holes.
assaying All field logging or field sampling data was
done using a laptop and uploaded into the
company
Datashed database and validated by company
database
personnel.
All assay files were received in digital
format from ALS Laboratories. All
Niton handheld XRF soil data was downloaded
from the instrument in digital format. Data
was uploaded into the Altona
Datashed database and validated by company
database personnel. No manual data inserts
took
place.
No adjustments have been applied to the
results.
Location Soil sample locations are surveyed using
of data handheld GPSs (Garmin GSMAP78s) with an
points approximate 5 metre horizontal accuracy.
No new drillholes.
Collar coordinates of historical drill holes
by Placer and Australian Copper Miner at
Whippersnapper were not recorded in the
sou
rce reference annual reports CR4696 and CR27193
. Hole positions were located in the field
based on maps and descriptions in the
reports. For the most recent Placer RC
drilling
holes (TSP1,2, 3 and 4) are located with a
high degree of confidence. Collar locations
have been surveyed using a hand held GPS with
an approximate 5 metre horizontal accuracy.
The Grid is GDA94 MGA Zone 54.
Data The soil sample grid spacings are 20 x 20
spacing metres
and at Hobby and 20 x 40 metres at Harvest. In
distribut the
ion areas
surrounding the anomalies spacing is typically
20 x 200 metres.
OrientatioNot applicable, no new drill data reported.
n of data For referenced historical drilling by Placer
in at
relation
to Harvest mineralisation is interpreted to
geologica strike approximately
l north
structure-south with unconfirmed dips subvertical to
steeply east dipping. Drilling was towards
the west or east generally at 60 degree dips
and is deemed appropriate.
Sample Soil samples are collected and bagged into
security pre-numbered plastic clip-lock bags. Unique
sample numbers were retained during the whole
process.
Samples were collected and delivered to the
Altona field office daily as they were
collected.
Soil samples were retained for reference and
stored in Altona facilities in
Cloncurry.
All rock and umpire soil samples were then
catalogued and sealed prior to dispatch to
the laboratory by Altona staff.
Audits or Internal audits and reviews of key datasets
reviews collected by Altona have been undertaken.
Past exploration data by other explorers has
only been validated against the source
references.
Analysis of the results from the QA/QC samples
are routinely
analysed by the database manager and geologist
on a batch and campaign basis.
For laboratory analyses, the accuracy of key
elements such
copper and gold, was acceptable and the field
duplicate assay data was unbiased and shows
an acceptable level of
precision.
For handheld Niton XRF analyses the data may
display
a consistent bias against the reference data. I
n contrast laboratory umpire samples from the
reported soil anomalies displayed no bias and
an acceptable level of precision for the
purpose.
No external audits or reviews have been
undertaken.

No joint ventures apply.
There are agreements in place with the native

Kalkadoon people and with landholders.
No significant historic sites or national

ExplorationVery small historical surface workings (slots
done by and shallow shafts) on narrow high grade
other copper oxide veins/gossans exist at
parties
Harvest and Hobby. These are more extensive
at
Harvest.
Rockchip sampling has been undertaken around
the historical workings at Hobby
anomal
ies by pervious explorers. No systematic soil
sampling, ground geophysics
or drilling has been undertaken.
Previous exploration has been undertaken by
several parties at
Harvest since the 1970s. Early exploration
was by Australian Copper Mines N.L. and
Aquitane Australia Minerals Pty Ltd in the
1970s, and CRA and Placer in the 1990s.
The majority of this work
was surface mapping and sampling. Four
shallow diamond drill holes were drilled by
Australian Copper Mines (1971, CR4696) in
the
south
ern portion of the main anomaly. No assay
data is reported for these holes although
graphic logs show mineralised copper
intercepts consistent with subsequent nearby
drill holes conducted by Placer.
It is unclear from the report whether the diam
ond holes were submitted for analysis or the
graphic logs
refl
ect visual estimates for copper. Placer
(1995) drilled 4 RC holes in the
north
ern portion of the main anomaly. The holes
drilled parts of the mapped copper anomaly
and recorded copper and gold mineralisation
over broad widths.
Geology Mineralisation is considered to be
hydrothermal,
stratabound and structurally controlled
following internal competency, chemical and
permeability
contrast.
Mineralisation occurs both as fine-grained
pervasive
dissemination
s and in coarse grained veins. Mineralisation
occurs as sulphide
minerals
under a shallow, approximately 25 metre,
oxidised cap. Copper sulphides include
chalcoc
ite, chalcopyrite and bornite. The majority
of the oxide mineralisation consists of
copper oxides (malachite) and silicates.
Drill hole Not applicable, no new drill data reported.
