JAGUAR OPERATION
TRIUMPH PROSPECT - SIGNIFICANT MASSIVE SULPHIDE INTERCEPTS
Highlights
Independence Group NL ('IGO' or the 'Company') is pleased to announce significant new results from a Diamond drilling programme recently completed at the Triumph Prospect. Recent Diamond drilling has outlined a new VMS deposit of massive to semi massive sulphide mineralization at the Triumph Prospect, located 6km north of the Jaguar Processing Plant. Intercepts include:
29.4m (true width 25.3m) @ 13.0% Zn, 0.7% Cu, 128g/t Ag and 0.3g/t Au from 305.6m in hole
15TRDD010 including:
9.3m (true width 8.0m) @ 14.8% Zn, 1.2% Cu, 150g/t Ag and 0.6g/t Au from 323.0m, and
12.1m (true width 10.4m) @ 0.1% Zn, 3.0% Cu, 57g/t Ag and 0.2g/t Au from 335.0m.
8.6m (true width 7.4m) @ 10.1% Zn, 0.1%Cu, 200g/t Ag and 0.4g/t Au from 376.4m in hole
15TRDD007
3.5m (true width 3m) @ 9.6% Zn, 0.5%Cu, 147g/t Ag and 1.6g/t Au from 287.5m in hole

'These results confirm our earlier interpretation that the Triumph Prospect may represent a significant VMS system' said IGO Managing Director, Peter Bradford. 'Whilst further work is required to define the continuity and extent of mineralisation, Diamond drilling is encountering grades and thicknesses that provide strong encouragement that Triumph may potentially represent an additional source of ore for the Jaguar Operation.'
'In parallel to the exploration work programme at Triumph, the Company is developing a hanging-wall drill drive at the Bentley Mine which will provide a drill position to upgrade the Flying Spur resource classification along with testing the down-plunge continuity of the Arnage Deposit,' Mr Bradford said.'We look forward to continued exploration success from both work programmes.'
Details
IGO has recently completed a Diamond drilling programme comprising ten holes for 4,970m at its emerging
Triumph Prospect located some 6km north of the Jaguar Processing Plant.
Previous drilling programmes at Triumph, which were wide-spaced and designed to test a surface geochemical anomaly, identified an extensive shallowly, south-plunging mineralised system of generally low- moderate zinc grades. The recently completed drill programme was designed to test the shallower, up-plunge parts of the system where copper stringer mineralisation previously, intersected in the footwall rhyolite in-hole
14TRDD002, indicated proximity to a feeder zone to the system.
The majority of holes were drilled on four sections nominally 80m apart and were targeted to infill or step-out from existing drill holes on 40m centres (Figure 1). Five holes from this programme returned significant widths of massive to semi-massive sphalerite-rich sulphide mineralisation. Assay results have been received for three holes and they include the high-grade intercepts listed above. A list of significant intercepts to date is provided in Table 1.
The up-plunge zone of mineralisation has been drilled below about 270m depth from surface, over a down- plunge distance of approximately 300m. The mineralisation remains open up- and down-plunge (Figure 1). The high variability in mineralisation thickness from 2m to 40m over relatively short distances is interpreted to be a function of structures active at the time of mineralisation was formed. As with other deposits in the Jaguar VMS Belt, mineralisation displays intense footwall alteration, associated with locally strong copper
mineralisation.
Further Work
Follow-up drilling will be planned after all assay results have been received and the 3D geological interpretation has been updated.

Criteria

Commentary
|
Verification of sampling and assaying
|
Drill core are checked for mineralised zones by senior site base geologists. Assay data are checked by senior IGO geologists.
|
Verification of sampling and assaying
|
There were no twinned holes drilled.
|
Verification of sampling and assaying
|
Data are entered in the field electronically into Toughbook computers running the acQuire geological data entry system. Data are then transferred electronically to a dedicated Microsoft SQLServer database. Data are verified by routine internal software processes for data integrity and by manual checking by project and
supervising geologists.
|
Verification of sampling and assaying
|
There are no adjustments to primary assay data.
|
Location of data points
|
DD collars are located using RTK differential GPS for an accuracy of better than 0.3 m.
|
Location of data points
|
DD holes are downhole surveyed using a north seeking gyro survey tool. Data are captured every 5 metres.
|
Location of data points
|
Grid system used is MGA_GDA94 Zone 51 and local JMG mine grid.
|
Location of data points
|
Topographic control is from survey methods described above.
|
Data spacing and distribution
|
DD spacing is defined on geological criteria considered appropriate to define the scale of mineralisation in each prospect. Nominal drill spacing is 80-160 metres. Drill spacing is shown in the accompanying sections.
|
Data spacing and distribution
|
Data distribution is regarded as appropriate for the style of mineralisation sought, the stage of the exploration and the geological conditions encountered.
|
Data spacing and distribution
|
DD samples are selected on geological criteria and are not composited.
|
Orientation of data in relation to geological
structure
|
DD holes are sited to intersect mineralisation perpendicular to orientation to minimise sample bias - holes
are generally drilled towards the footwall at 66° magnetic and with a 60° dip from horizontal.
|
Sample security
|
Samples are stored on site then transported to the Perth laboratory via truck. Samples are stored in a locked yard at the laboratory and are electronically tracked. Pulps are stored in a locked shed at both the laboratory and when returned to site.
|
Audits or reviews
|
Sampling techniques and data QAQC is reviewed by Company based senior geologists.
