Sampling techniques

Soil samples are surface samples (top 20cm) 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 <1m2  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 assay data and laboratory tests

Soil Samples

Soil samples were routinely analysed for copper (and a suite of other elements) using a 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) digest 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.

Verification of sampling and assaying

Results were checked by several Altona personnel.

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 of data points

Soil sample locations are surveyed using handheld GPS’s (Garmin GSMAP78s) with an approximate 5 metre horizontal accuracy.

No drilling.

The Grid is GDA94 MGA Zone 54.

Data spacing and distribution

The soil sample grid spacings are 20 x 20. In the areas surrounding the anomalies spacing steps out typically to 40 x 80 metres and 20 x 200 metres.

Orientation of data in relation to geological structure

Not applicable, no new drill data reported.

Sample security

Soil samples are collected and bagged into 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 reviews

Internal audits and reviews of key datasets 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.

Mineral tenement and land tenure status

Reaper sits within EPM 25761, 100% owned by Altona Mining Ltd. 

No joint ventures apply.

There are agreements in place with the native title holders, the Kalkadoon people and with landholders.

No significant historic sites or national parks are located within the reported exploration sites.

The EPM’s were granted in late 2015 and is in good standing.

Exploration done by other parties

Very small historical surface workings on narrow high grade copper oxide veins/gossans exist at Reaper.

At the Reaper anomaly a small number of rockchip samples had been collected by pervious explorers; the tenor of copper assays from these samples are similar to those collected by Altona no gold assays are available; these are not reported as their locations could not be verified and may be incorrect with assays anomalous in copper from rocks outside the strongly anomalous areas. No systematic soil sampling, ground geophysics or drilling has been undertaken.

Geology

Mineralisation is considered to be similar to other IOCG deposits in the area and exhibits feldspar-quartz-amphibole alteration.

Drill hole Information

Not applicable, no new drill data reported.

Exploration results are not being reported for the Mineral Resource area.

Data aggregation methods

Exploration results are not being reported for the Mineral Resource area.

Relationship between mineralisation widths and intercept lengths

Exploration results are not being reported for the Mineral Resource area.

Diagrams

Figures 1 and 2.

Balanced reporting

Exploration results are not being reported for the Mineral Resource area.

A full compilation of available data collected by Altona and compiled from previous explorers has been published in Altona ASX releases dated 1 August 2016 and 6 September 2016.

Other substantive exploration data

Exploration results are not being reported for the Mineral Resource area.

Heritage clearance surveys have been completed ahead of drilling.

Further work

Additional work in the future will consist of RC and diamond exploration drilling, prospect scale mapping, further surface sampling and ground based geophysics such as IP.
