ASX Announcement
8 November 2017
INITIAL RC ASSAYS AND NEW DEEP EM TARGET IDENTIFIED AT COLLERINA
Helix is undertaking a six-hole exploration drill program at the Collerina Copper Deposit: 3 RC holes targeting around the previously defined Central Zone and 3 RC/diamond holes targeting Central Zone dip plane extensions. Drilling is being supported by DHEM surveys undertaken in holes within, or adjacent to, the Central Zone dip plane.
RC Drilling Results
-
First hole of the drill program, targeting an eastern lateral extension of the Central Zone, has returned a wide interval of copper, zinc and gold mineralisation.
-
CORC078 returned: 10m @ 1.4% Cu, 1.1% Zn and 0.15g/t Au from 178m within 16m @ 1% Cu and 0.7% Zn from 173m
-
Delivers an extension to the Central Zone and is approximately 60m up-dip and 60m east of previous intercepts,and.
-
Increases the overall dip-plane width of the Central Zone.
-
Two infill RC holes have been completed at shallower levels within the Central Zone. CORC082 returned 1m @ 2.3% Cu and 0.2g/t Au from 93m within 4m @ 0.7% Cu, whilst CORC079 intersected an EastWest fault zone.
New EM Conductor Targets
-
Preliminary modelling of DHEM undertaken this week in the 3 RC pre-collars and a selected historic deep RC hole identified a conductive trend in the dip plane extension of the previously delineated Central Zone mineralisation.
-
An off-hole conductor (partially defined) with approximate dimensions of 80m X 100m has been modelled in the dip plane, below previous drilling. The plate has similar conductance to the Central Zone mineralisation (150-200 Siemens). The plate position is open up plunge, down plunge and down dip.
Diamond Drilling Ongoing
-
A diamond drill rig has completed diamond core tails on two of the three RC pre-collared drill holes.
-
The first two diamond tailed holes have intersected stringer primary sulphide mineralisation in the dip plane in CORC084 on the western side of the target zone (the DHEM anomaly lies east of this hole) and CORC080 which lifted into a fault zone.
-
The third diamond tail is underway. It is located behind CORC080 and is targeting a position up dip and up plunge of the new DHEM conductor described above.
Helix Resources Limited (ASX:HLX) ( Helix or the Company ) is pleased to announce initial results from the Phase 2 drilling program currently underway at the Collerina Copper Project in central NSW.
The Phase 2 exploration program consists of three reverse circulation (RC) and three RC/DD drill holes .
The three RC drill holes were planned to test for:
- An eastern lateral extension of the Central Cone (CORC078), which has been successful; and

- Possible primary sulphide extensions within the Central Zone at shallower levels.
Three deeper RC/DD holes were planned to test for mineralisation in the Central Zone dip plane to a depth of approximately 300m from surface. DHEM undertaken on the RC pre-collars and a selected historic deep RC hole has produced a partially constrained EM conductive anomaly within the interpreted Central Zone dip plane. This conductive anomaly trend is being targeted with the currentdrill hole.
Commenting on the initial results Helix Managing Director, Mick Wilson, said, “This is an excellent start to our drilling program at the Collerina Copper Deposit. A wide copper interval that expands the known extent of the Central Zone endowment to the east, combined with a drill hole currently underway targeting an open DHEM conductor position modelled down dip of the Central Zone delivers promise for the potential of the Collerina Copper Deposit.”
RC Extensional Result
The first RC hole of the Phase 2 drill program (CORC078) has returned a wide interval of copper,zinc andgold mineralisation that represents an eastern extension of the Central Zone.
CORC078 was drilled to a depth of 214m and was designed to target the modelled potential for an eastern extension to the Central Zone mineralisation. The hole returned an interval of 10m @ 1.4% Cu, 1.1% Zn & 0.15g/t Au from 178m, within 16m @ 1% Cu, 0.7% Zn from 173m. The hole covers a portion of the Central Zone where a gap in the drilling pattern was present. The intercept comprises a 10m wide zone of massive and semi-massive sulphide with variable stringer sulphide zones present either side (refer photo 1).

Photo 1: Mineralised zone in CORC078 returning 10m @ 1.4% Cu, 1.1% Zn and 0.15g/t Au from 178m
The result has delivered an eastern extension to the Central Zone, with the interval being located approximately 60m up-dip from CORC032 (6m @ 2.2% Cu and 0.3% Zn from 192m) and 60m east of CORC022 (8m @ 2.4% Cu and 1.3% Zn). Whilst this intercept is more pyritic than previous intercepts nearby, such localised variation in copper content is not uncommon in these systems. Importantly, the drilled dip extent of the Central Zone primary sulphides is averaging approximately 150m in the dip plane.

Central Zone shallow infill drilling
Two further RC holes have been completed at shallower levels within the Central Zone. The drill holes were designed to fill in gaps in the drill pattern between the oxide zones of the Central Zone and deeper primary sulphides already defined below. CORC082 has returned 1m @ 2.3% Cu and 0.2g/t Au from 93m within 4m @ 0.7% Cu in primary sulphides. CORC079 intersected an East-West fault zone at the targeted depth and returned no significant assay result.
New EM Conductor Targets
Helix has undertaken DHEM surveys as part of the current exploration program in 4 holes in order to assist with the targeting of the deeper holes.
Modelling of DHEM data derived from the 3 deep RC pre-collars and a selected previous deep RC hole has identified a new conductive trend in the dip plane of the Central Zone mineralisation. A partially defined offhole DHEM conductor was identified east and down dip of CORC039; which is one of the deeper holes drilled at Collerina to date (392m downhole). This newly modelled EM conductor plate sits within the dip-plane target zone, has a conductance similar to the central zone mineralisation at 150-200 Siemens and importantly remains open up plunge, down plunge and down dip.
Helix has commenced diamond drilling today of CORC081, a hole that is designed to test the zone in the dipplane below the main central zone, up plunge of the modelled DHEM plate ( which remains open due to its partial definition ) and down plunge from stringer sulphides intersected in CORC084 ( assays pending ).
Further drill and assay results from the Phase 2 exploration program at Collerina are expected over the coming weeks.

Background
Phase 1 shallow RC drilling at the Collerina Copper Deposit completed earlier this year identified new nearsurface oxide copper zones, discrete from the previously identified Central Zone. The scale and tenor of the intercept results identified in these new zones were consistent with previous oxide intersections over the Central Zone. The new zones expanded the strike extent of copper mineralisation by approximately three times to over 500 metres.
Subsequent DHEM identified discrete EM conductors beneath these new copper zones. By way of context, the Central Zone mineralisation is characterised by broad zones of copper in oxides from approximately 50m below surface which then transitions to the high-grade copper sulphide mineralisation from approximately 80m below surface. The mineralisation has exhibited a local plunge continuity displayed in drill results received to date, with the massive sulphides extending over the currently identified plunge extent of at least 300 metres.
The target corridor (refer to Figures 1, 2 & 3) represents the down dip extension from surface copper geochemistry, a 300m wide zone of surface moving loop EM and DHEM anomalism and the direct dip extensions beyond the massive sulphide intersections identified in previous drilling.
