ALTONA MINING LIMITED: Drilling Begins at Roseby South
(firmenpresse) - Drilling begins at ROSEBY SOUTH
- Drilling to target three new prospects - Reaper, Hobby and Harvest
- RC drilling program consists of 15 - 25 holes and 2,500 metres of drilling
- Initial drilling to target high-tenor copper-in-soil anomalies
- Anomalies comparable to Altonas Little Eva deposit
- Drilling expected to be completed by November 2016
Altona Mining Limited (Altona or the Company - Altona Mining: SRIG Deal Being Finalised & Huge Exploration Potential http://www.commodity-tv.net/c/mid,1323,Interviews/?v=296936) today announced drilling has commenced at the Companys 100% owned Roseby South Project (Roseby South) near Mt Isa in Queensland (Figure 2).
Roseby South immediately adjoins the southern boundary of the Companys Cloncurry Project and MMG's major underground zinc mine development at Dugald River (Figure 2). The Cloncurry Project is the subject of a US$235.5 million proposed joint venture (JV) with Sichuan Railway Investment Group (SRIG). Please refer to ASX release dated 2 June 2016 for further information regarding the SRIG JV.
Roseby South is a 100% Altona-owned exploration tenure. It does not form part of the arrangements with SRIG.
The planned reverse circulation drilling program consists of approximately 15 to 25 holes and 2,500 metres of drilling at Harvest, Hobby and Reaper (Figure 1). Altona will also drill test one or two other prospects.
At each prospect, large copper-in-soil anomalies greater than 1,000ppm (0.1% copper) have been defined. The anomalism is of similar size and tenor to the Cloncurry Project's Little Eva deposit (546,000 tonnes contained copper and 295,000 ounces of gold, Appendix 3). Outcrop and float rock samples returned up to 14.4% copper and 0.74g/t gold at Harvest; 23.3% copper and 2.9g/t gold at Hobby; and, 0.8% copper and 1.54g/t gold at Reaper.
The targets were identified this year and were reported in ASX releases dated 1 August 2016 (Harvest and Hobby) and 5 September 2016 (Reaper). Please refer to these releases for more detailed prospect summaries.
No previous drilling has been undertaken at Hobby and Reaper, whereas reconnaissance drilling at Harvest by past explorers returned significant mineralised intersections. Third party agreements and Aboriginal heritage clearances required prior to drilling have been secured.
Drilling is expected to be completed by early November 2016 and approximate costs are estimated at $250,000.

About Altona
Altona Mining Limited is an ASX listed company focussed on the Cloncurry Project in Queensland, Australia. The Project has Mineral Resources containing some 1.65 million tonnes of copper and 0.41 million ounces of gold. The first development envisaged is the 7 million tonnes per annum Little Eva open pit copper-gold mine and concentrator. Altona has completed a Framework Agreement with Sichuan Railway Investment Group to fully fund and develop Little Eva. Little Eva is permitted with proposed annual production(1) of 38,800 tonnes of copper and 17,200 ounces of gold for a minimum of 11 years. A Definitive Feasibility Study was published in March 2014.
1Refer to the ASX release Cost Review Delivers Major Upgrade to Little Eva dated 13 March 2014 which outlines information in relation to this production target and forecast financial information derived from this production target. The release is available to be viewed at www.altonamining.com or www.asx.com.au. The Company confirms that all the material assumptions underpinning the production target and the forecast financial information derived from the production target referred to in the above-mentioned release continue to apply and have not materially changed.
Competent Persons Statement
The information in this report that relates to Exploration Targets, Exploration Results, Mineral Resources or Ore Reserves is based on information compiled by Mr Roland Bartsch, BSc (Hons), MSc, MAusIMM, and Mr George Ross, MSc, MAIG.

APPENDIX 1: TABLE 1 OF THE 2012 EDITION JORC CODE
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.
Section 1: Sampling Techniques and Data
Criteria Commentary
Sampling Soil samples are surface samples (top 20cm)
techniques sieved to -2mm to obtain a ~100g sample size.
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.

Quality of Soil Samples
assay Soil samples were routinely analysed for
data and copper (and a suite of other elements) using
laboratory a
tests
Niton XL3tGOLDD+ 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 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 detection limit
of 0.01ppm and upper detection limit of
100ppm.

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. In 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.
