Rochford Copper-Gold Trend Update
Helix Resources Limited (ASX:HLX) ( Helix or the Company ) is pleased to provide an exploration update for the activities underway on the Rochford Copper–Gold Trend.
HIGHLIGHTS
GEOPHYSICS
-
A Moving Loop Electromagnetic (MLEM) Survey covering the southern half (600m of strike) of the
-
Bijoux Prospect within the broader Rochford Trend has been completed and the data modelled.
-
A partially defined NW trending bedrock EM response has been identified in the two northern-
-
most survey lines (central zone of the Bijoux Prospect).
-
This target position is coincident with broad-spaced copper in auger-soil anomalism , a
-
northwest trending magnetic feature and immediately flanks the western side of a localised topographic high .
-
The EM target is open to the northwest, southeast and east and represents a high priority drill
-
target for copper sulphides along the trend.
FIRST-PASS LABORATORY ASSAYS
-
Anomalous copper was recorded in heavily weathered bedrock (depletion zone) in 3 out the 4 scout
-
holes drilled at both ends of the 1.7km Bijoux Prospect;
-
First-pass 4m composite base metal laboratory assays of samples from the recent scout
-
drilling program have confirmed the anomalous copper results from previously reported pXRF readings
-
Laboratory results returned BJRC003 - 24m @ 0.24% Cu from 10m; and BRRC004 - 12m @
-
0.18% Cu from 14m.
-
Further sampling of the previously unsampled intervals has been undertaken with the precious and
-
base metal results yet to be received from the lab.
FORWARD PROGRAM
-
These early results show potential for a polymetallic (Cu-Zn-Pb-Ag-Au) mineral system to be
-
present on the Rochford Trend, with scout drilling yet to test tested the highest priority parts of the system as highlighted by the MLEM survey.
-
The results so far command follow-up work, with clear geophysical and geochemical vectors
-
present from the limited programs completed to date.
-
Planning is underway for additional MLEM surveying in the New Year as soon a geophysical crew
-
can be engaged; It is intended to to extend the EM survey area north, east and south to fully cover the target trend at the Bijoux Prospect.
-
Infill auger sampling over the central and southern extension of the Bijoux Prospect is also planned.
-
The combination of the results from these programs will assist in defining priority areas for further
drill-testing on this prospective trend.

Helix Executive Chairman, Peter Lester, said: “The initial results from the geophysical and geochemical scout programs on the Rochford Trend are very encouraging. We are also buoyed by the regionally significant greenfield discoveries of both Aurelia (Federation) and Aeris (Anomaly K/Constellation) recently in the district. The 12km long Rochford Trend is book-ended by gold and base-metal deposits and has seen little or no modern exploration prior to Helix identifying its prospectivity in late 2019. The results so far are strong indicators of the need for further work, with extensional MLEM surveys and auger soils a priority at Rochford in the New Year. Through good exploration, Helix continues to build a value proposition from its internally generated copper and gold exposure in the Cobar District”.
Scout RC drilling of four holes in two locations along the Rochford Trend was undertaken as part of the November 2020 Cobar Gold Project drilling program. The 12km long Rochford Trend lies on the eastern edge of the Cobar Gold Project, between the polymetallic Pipeline Ridge Deposit (Southeast) and the Canbelego/Mt Boppy copper and gold deposits (Northwest).
Of significance, the two southern holes at the Bijoux Prospect returned broad zones of copper in pXRF readings, in heavily weathered and strongly altered bedrock. The elevated in copper is likely to represent a depletion zone in this mineral system.
Initial 4m composite sample laboratory results, following up the field pXRF readings, in these holes have returned:
-
BJRC003 24m @ 0.24% Cu from 10m following-up pXRF readings of 38m @ 0.22% Cu* from surface (peak reading of 0.54%Cu)
-
BJRC004 12m @ 0.18% Cu from 14m following-up pXRF readings of 33m @ 0.13% Cu* from 4m (peak reading of 0.50% Cu)
-
pXRF readings are semi-quantative and are deemed to only provide an indication of base metal mineralisation. In addition, the pXRF device is not able to detect gold that may be present in the samples.
The tenor of the copper in these two holes is slightly higher, over narrower widths than the initial pXRF readings, however sampling of the entirety of all holes was also conducted, with those assays pending.

About the Bijoux Prospect
The Bijoux Prospect was initially defined by a 1.7km x 0.7km copper in soil anomaly within the larger Rochford Trend. The prospective zone was initially identified from field mapping and a cluster of pXRF readings from the Auger soils, with readings of up to 580ppm Cu. Importantly the copper anomaly coincides with the subtle northwest ridgeline, a northwest trending magnetic feature, and favourable lithologies, hosting brecciated ironstones.
This prospect has similarities to Aurelia Metals Limited’s recent polymetallic Federation Deposit discovery, and these initial results are considered very significant in that context given its location along strike from Pipeline Ridge and surrounding deposits (Southeast) and both the Canbelego Copper Deposit (70% Helix, 30% Aeris) and the high grade Mt Boppy Gold Mine (North-Northwest), refer Figure 1 and 2.
The material noted on surface, has a similar texture to the brecciated massive sulphide hosting the highgrade copper at the Canbelego deposit to the north. The brecciated iron-rich material is similarly surrounded by a matrix of iron dominated material to form the sub-cropping gossan.
The iron-rich units identified at surface, may relate to massive sulphide accumulation in primary rock below. These initial 4 scout holes, designed to test the gossan beneath surface, all intersect heavily weathered bedrock that has been altered to clays. All holes ended in bedrock outside the target unit, where a mafic intrusive unit and sediments appear to be strongly chlorite and sericite altered.
Now that a mineralised horizon has been confirmed and surface MLEM has identified a partially defined target trend, furvey EM Surveys and infill soils are a priority for the New Year. Further drilling will be considered following the review of the soil results and data from the extensional MLEM geophysical survey.

The Rochford Copper Trend covers 12km of strike south-east of Canbelego Copper deposit, the Mount Boppy goldmine and lies northwest of the Pipeline Ridge polymetallic deposit. With direct access from the Barrier Highway, the trend is parallel to the Cobar Trend and represents a structural repeat in the Devonian (Cobar aged) Kopjye Shelf sedimentary zone.

About Helix Resources
Helix Resources Limited (ASX:HLX) has been listed on the ASX since May 1986, exploring and developing projects in Australia and globally.
The Company’s current focus is its exciting copper and gold projects located near Cobar in New South Wales. The Cobar Region is highly endowed, with a number of gold and base metals mines active in the region including the CSA Mine, Peak Mine, Tritton Copper Operations and Hera Mine.
At the Company’s 100% owned Collerina Copper Project , the Company discovered the VMS-hosted Central Zone deposit in 2017, with a maiden Mineral Resource defined soon after. The Company is actively exploring in and around the Mineral Resource, looking for both clusters of mineralisation as well as potential extensions to the Mineral Resource.
To the west, the Company’s 100% owned Cobar Gold Project has identified a number of Mineral Resources, mainly focused around high-grade historical workings. The geology and structure at these prospects are similar to that seen at the 4Moz Peak Gold Mine to the north, where deposits are known to extend to over 1600m depth. The Company is looking to increase the Mineral Resources as well as assess near term mining and processing opportunities.
More recently, the Company identified a 1.7km x 0.7km northwesterly trending zone, which it has called the Rochford Trend . Within the trend, the Bijoux Prospect was the first drill tested by the Company, with wide zones of anomalous copper identified by pXRF analysis in the field. Detailed gold and base metals assays are pending.
