ASX Announcement
5th November 2014
Surface samples above VTEM anomaly return high grade copper and zinc - Sulitjelma
Update on Drake and JV partner, Panoramic Resources' VTEM assessment of 7 anomalies prospective for copper /zinc at Sulitjelma Very encouraging results from preliminary field inspection and rock chip sampling around Anomaly 3. Results include -
o Copper grades up to 10.7%
o Zinc grades up to 15.1%
o Anomalous silver to 53 g/t and cobalt to 0.1%
Drake, with its joint venture partner, Panoramic Resources Limited, advises that final data for it's VTEM+ electromagnetic and magnetic surveying, flown in August this year at its
Sulitjelma Project in Northern Norway has been received and is being processed and
modelled.
Drake announced preliminary interpretation of the results on 8/10/14, revealing a total of seven anomalies of interest and making particular reference to Target 3, a 4.5km long VTEM+ anomaly occurring on the less understood southern extremity of the eastern mineralised zone (Fig 1). Field mapping immediately following the recent VTEM program confirmed the presence of outcropping massive sulphides. Dump samples from old workings and composite chip samples of local outcrop have returned very encouraging results (Table
1).

Table One: Details of samples collected at Anomaly 3 - Sulitjelma.
w w w .d ra ke re s o u r c e s .co m .a u
Drake's CEO, Jason Stirbinskis said "Target 3 caught our interest immediately because this area of Sulitjelma has seen very little historic activity and no drilling except for near surface (~1m deep) surface sampling holes.
"Five of the other targets of interest lie within the western thrust which is an area of known massive sulphide mineralisation mapped over a ~10km north / south direction and the sixth occurs near historic copper / zinc mines such as Giken."

Sulphide horizon
View of anomaly 3 with sample area in the centre left.
Fig 2. Plan showing location of anomaly 3, on topography with massive sulphide outcrops in red, and sample locations. At the sample SJV0006-0009 location samples were collected from material blasted in 1976, from outcrop at the bottom of a cliff, comprised of a 25 cm thick massive, banded, fine grained sulphide bed, of which the upper 10 cm is pyrite- dominated, Zn-rich sphalerite-chalcopyrite ore (SJV0006), and the lower 15 cm is pyrrhotite- dominated sphalerite-chalcopyrite ore (SJV0007 and 8). Frequent thin pyrrhotite-dominated sulphide bands occur in the sericite-chlorite schist (SJV0009,) both above and below the massive bed. Total mineralised thickness is approximately 1 m.
3
Anomaly 3 is a strong strike-extensive anomaly (fig 3 & 4) approximately 4.5kms long. Present modelling suggests the conductive horizon coincides with the sampled outcrops and extends typically ~200 m into the hill.
Attention will now move to the assessment of other anomalies identified from the VTEM+
program. Final appraisal, recommendations and commentary is expected in December.

4.5km long is shown.

Fig 4. Section showing modelling of VTEM line 1420, channels 41 to 45. A good fit was achieved for the modelled response (red profiles) to the observed response (black profiles). The projected outcrop of the model plate is near coincident with sample SJV001 (>10 % Cu); the difference is well within the model error.

Commentary

Sampling
techniques
|
• Nature and quality of sampling (eg 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.
• Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
• 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 (eg '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 (eg submarine nodules) may warrant disclosure of detailed information.
|
Samples 1, 3, 4 and 5 are composite, random chip samples taken from
outcrop, no channel samples were taken.
Sample 2 is a fist sized sample of felsic tuffite with a 1 cm thick massive- layer of sphalerite and chalcopyrite, from outcrop.
Samples 6-9 are dump samples. Dump material of massive sulphide (6-
8) were scarce, and the three samples are all fist sized, representing 7-
10 cm thickness of the banded ore. As the ore thickness here was only
25 cm (10 cm pyrite dominated and 15 cm pyrrhotite dominated) it is believed that the samples are relatively representative.

Mineralisation dips at 20 to 40 deg to the north east.
Composite random chip samples 1, 3, 4 and 5 taken from outcrop would be reasonably representative. Sample 2 was a fist sized sample of felsic tuffite with a 1 cm thick massive-layer of sphalerite and chalcopyrite, from outcrop. Samples 6-9 were dump samples. Dump material of massive sulphide (6-8) were scarce, and the three samples were all fist sized, representing 7-10 cm thickness of the banded ore. As the ore thickness here was only 25 cm (10 cm pyrite dominated and 15 cm pyrrhotite dominated) it is believed that the samples are relatively representative.

o dip and azimuth of the hole
o down hole length and interception depth
o hole length.
• If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from
the understanding of the report, the Competent Person should clearly explain why this is the case.
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.
• 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.

• 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.
