ASX Announcement
13 July 2017
SHALLOW DRILLING IDENTIFIES NEW COPPER ZONES AT COLLERINA
-
Reverse Circulation (RC) drilling has identified four new near‐surface oxide copper zones expanding the Collerina Copper Deposit footprint.
-
Scale and tenor of results are consistent with previous oxide intersections over the Central Zone of the Collerina Deposit.
-
These new zones expand the known aggregate strike of copper mineralisation approximately threefold to more than 500m.
-
The drilling results confirm the new geological and structural interpretation at Collerina.
-
Geophysical surveys (DHEM) targeting primary copper sulphides in the dip and plunge extensions of these new zones are underway.
-
A follow‐up drilling program is being planned to target these down dip/plunge extensions this quarter.
Helix Resources Limited (ASX:HLX) ( Helix or the Company ) is pleased to advise that the recent RC drilling program at the Collerina Copper Deposit has been completed and assay results received.
This program has successfully identified four additional near‐surface oxide copper zones adjacent to the existing Central Zone mineralisation. The identification of these new zones has expanded the known Collerina aggregate strike extent to in excess of 500 metres, an approximate threefold increase.
It is encouraging that the scale and tenor of the assay results from the newly identified oxide copper zones are consistent with previous oxide drill intersections over the Central Zone of the Collerina Deposit.
A new drill program is currently being planned, with the assistance of downhole electromagnetics (DHEM), to target copper sulphide extensions to these newly identified copper oxide zones.
Helix Managing Director, Mick Wilson, commented:
“The identification of four new copper oxide zones and the extension of the aggregate strike of copper mineralisation at Collerina to more than 500m is extremely encouraging and validates the potential of the project.
The scale and tenor of the oxide mineralisation of the new zones is consistent with the shallower oxide portion of the Central Zone where massive sulphide mineralisation has been confirmed down plunge for more than 500m.
Today’s results from the new zones and the upcoming downhole geophysical surveys will be key to define drill targets for our next program, targeting copper sulphide mineralisation in potential depth extensions.”

Collerina Deposit
The most advanced prospect at Collerina is the Collerina Copper Deposit. The Collerina Copper Deposit is defined by an open‐ended large copper‐gold soil anomaly. At surface, the central portion of the mineralised zone hosts one of three known historic shafts. The shaft is located in the hanging wall of a semi‐exposed gossan. The overall system trends in a north‐westerly direction.
Earlier drilling of the Collerina Deposit by Helix focussed on targeting the down plunge extent of the Central Zone mineralisation. Central Zone mineralisation has been identified along approximately 150m of strike at surface and is characterised by broad zones of low‐grade copper in oxides to approximately 60m below surface. Higher grade mixed oxides, chalcocite and patches of native copper are present in previous drilling results in the transition zone (approximately 60‐80m from surface). In fresh rock (approximately 80m below surface), high‐grade copper sulphide mineralisation has been intersected and is dominated by chalcopyrite, chalcocite and massive pyrite, with coincident sphalerite (zinc sulphide).
Previous drilling highlighted the remarkable local plunge continuity of the Central Zone mineralised system, commencing from the semi‐exposed gossan at surface. In particular, a zone of massive sulphides bearing high grade copper mineralisation was defined over a plunge extent of in excess of 500m. Individual peak values in 1m samples were up to 12% Cu, 1.5g/t Au and 4.6% Zn¹.
Subsequent drilling by Helix in late 2016 targeted further depth extensions of the Central Zone plunge in an east north‐easterly direction (see green shaded area in Figure 3). Intersected mineralisation transitioned from a massive/semi‐massive copper zone with coincident zinc to a stringer copper‐only style of mineralisation within the plunge plane. Closer to surface, RC drilling continued to show evidence for strike extensions beyond the Central Zone, however it was not clear how local folding and faulting was influencing the copper lenses and their distribution.

Earlier this year Helix commissioned an independent geological consultant to undertake a detailed structural review of the Collerina Deposit and surrounding region. This review concluded that locally the system had been kink folded and reverse faulted resulting in extensions of the Central Zone being variably offset. These extensions were interpreted to most likely be present nearby and located south, southeast and northwest of the positions in the system that had been targeted by drilling to that point.
This interpretation formed the basis of the geological model that was tested with the recent shallow RC drilling program. The commencement of this program was announced by Helix on 15 May 2017 ( “Drilling underway at Collerina Copper Project” ).
Recent RC Drill Program
The recent exploration program was focussed on areas up‐dip of a footwall marker horizon. Drilling targeted the identification of new oxide zones of copper mineralisation surrounding the Central Zone (see pink shaded areas in Figure 3).
This drill program consisted of shallow slim‐line RC drilling to a maximum downhole depth of 114m. It was designed and constructed on the basis of the revised geological and structural model for the Collerina Deposit. The program saw 21 holes drilled for a total of approximately 1,900m with some weather delays during the program.
Drilling was designed to test for potential copper mineralised positions above the footwall marker horizon. The marker horizon had been mapped and its extensions interpreted from magnetics during the geological and structural review. The marker horizon showed evidence for kink folding and fault off‐sets, suggesting a similar orientation was likely for the extensions of the Collerina copper mineralisation (refer Figure 3).
Key results
The drilling successfully identified four new zones of oxide copper mineralisation. The new mineralised zones are shown in Figure 4 and identified as:
-
Southeast offset (Zones 3 and 4);
-
South extension (Zone 2); and
-
Northwest extension (Zone 1).
Key drill intercepts in each new zone are as follows.
Southeast offset (Zones 3 and 4)
CORC060 returned 13m @ 0.3% Cu and 7m @ 2.4g/t Ag before intersecting an historic stope at 46m. Nearby CORC061 returned 10m @ 0.3% Cu from 51m. Approximately 50m along strike to the southeast CORC062 returned a thick intercept of 28m @ 0.2% Cu from 28m.
The Southeast offset has a current strike extent of at least 120m. The zone remains open along strike and is completely untested down plunge.
South extension (Zone 2)
Holes in the South extension (Zone 2) included 6m @ 0.2% Cu from 21m in CORC049 and 8m @ 0.2% Cu from 32m in CORC064. This zone abuts the Central Zone, but is poorly drill tested along the plunge plane. This zone has a strong copper‐in‐soil anomaly peaking at 2610ppm Cu¹.

To clearly illustrate the importance between the recent oxide results and the potential for additional primary copper sulphides at depth, the direct plunge position of this particular zone hosts two previously drilled holes. The results include 4m @ 2.4% Cu¹ from 54m in an historic CRA drill hole and 8m @ 2.4% Cu¹ from 123m in CORC022, which located approximately 220m down plunge from CORC064.
==> picture [490 x 396] intentionally omitted <==
Figure 4: New target zones surrounding the Central Zone at Collerina. Zones identified in recent drilling relate to four >400ppm copper in soil anomalies at surface.
Northwest extension (Zone 1)
The Northwest extension (Zone 1) returned 16m @ 0.2% Cu from 3m in CORC047 and 3m @ 0.6g/t Au and 13g/t Ag from 19m, before intersecting another historic stope. CORC063 returned 40m @ 0.1% Cu approximately 20m west and south of this position.
This zone is likely to be related to the western‐most known historic shaft. Nearby sub‐cropping gossan has returned rock chip samples up to 1.3% Cu and 8.4g/t Au¹. This zone has a current strike extent of 110m and remains open to the west.

Significance
The scale and tenor of the assay results in these newly identified oxide copper zones are consistent with previous oxide drill intersections over the Central Zone of the Collerina Deposit. Examples of oxide results above the high grade Central Zone include: 15m @ 0.1% Cu from 21m (CORC004), 20m @ 0.2% Cu from 18m (CORC023) and 50m @ 0.2% Cu from 8m (CORC024)¹.
The new zones have expanded the aggregate known strike extent at surface of the Collerina copper system to over 500m (a three‐fold increase) and provide a vector to potential copper sulphide mineralisation down plunge.
Critically, the new zones are all open down plunge as illustrated in the schematic long section shown below in Figure 5.

Collar locations are detailed in Table 1 and assay results are contained in Table 2.
Next Steps
Geophysical surveys (DHEM) are currently underway at Collerina in order to assist in targeting potential high‐ grade primary sulphide mineralisation in the dip and plunge plane of the new zones. Details of these surveys will be released in a separate announcement.
Once the results of the geophysical surveys have been processed and assessed, a follow up drilling program targeting the down plunge/dip planes of the new zones is planned to be undertaken during the current quarter, subject to the receipt of necessary approvals.

Regional Prospects
As part of the current program four shallow holes were recently drilled at the Max’s Folly Prospect. Drilling intersected historic workings evidenced by stope material and substantial water flow at approximately 30m downhole in the initial two holes drilled (approximately 50m apart). This suggests the historic workings present are more extensive than anticipated and appear to be of similar size and depth to the existing workings at the Collerina Deposit. Assay results for this drilling are awaited.
Planned exploration drilling at regional prospects, Yathella and Tindalls, where VTEM targets have been identified nearby to historic copper workings, has not been completed due to winter cropping in the paddocks hosting the prospects.

|---|---|
| The assumptions used for any reporting of metal _equivalent values should be clearly stated. _ |
|
| Relationship between mineralisatio n widths and intercept lengths 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. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
The program was designed to intersect various targets of base metal mineralisation . From our understanding of the Prospect, drilling is designed to intersect target mineralisation as close to perpendicular as practical. |
| Diagrams Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
Refer to figure 1 and 2 |
| Balanced reporting Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
Refer to Table 2, remaining results have not been received at the time of release and will be release as soon as they become available |
| Other substantive exploration data Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
Previously reported activities Refer to ASX announcements on www.helix.net.aufor details |
| Further work The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step- out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Additional geophysics, geochemistry and drilling will be undertaken to further assess the potential of the Collerina prospect and overall Collerina Project. |
