Helix has continued to work-up regional targets along the broader Collerina Copper Trend with over 1,000 first pass auger soil samples collected using the Company's Landcruiser mounted hydraulic auger rig.
All samples collected have been initially tested with a pXRF. Samples from anomalous areas are being sent to a certified laboratory to assay for precious and base metals. This pXRF work is being utilised during the programs to prioritise areas for infill, fast-tracking targeting for follow-up drilling.
Collerina South Prospect
Auger sampling has covered the south east extension of the host rocks of the Collerina Deposit, by approximately another 2km.
Whilst sampling to date is on a 100m x 200m grid, and much broader than the surface sampling over the Collerina Deposit, a pattern of complex folding (mimicking the complexity noted in the magnetics) appears to be emerging in the copper-in-soil anomalism at this Prospect. This pattern is very similar to the folding seen at the micro-scale in Collerina Deposit core. Thickening of sulphides o fold noses will be the priority areas to follow-up and infill at the Collerina South Prospect.
Widgelands NE Prospect
First-pass auger sampling has been undertaken on a 400m x 100m grid over the northern end of the Collerina Copper trend. Helix has previously reported surface rockchips returning up to 7.3% Cu and 0.5g/t Au from sub-cropping ironstones in this area (refer ASX ann 13 Feb 2018).
The Collerina Copper Trend bifurcates here with two prospective trends present. These trends continue NNW on Helix's Quanda and Honeybugle tenements to become the
Surface sampling across this target area identified a series of elongate copper-in-soil anomalies that coincide with geological, magnetic and subtle airborne EM trends. Infill sampling to refine anomalies is planned.
Tindalls Prospect
At the Tindalls Prospect area, two historic shafts (approximately 50m deep) are located on a favourable geological and structural trend. An Ironstone breccia similar to that seen at the Collerina Deposit has been mapped at surface along this trend. Interpretation of the local Magnetics suggests evidence for multiple deformation events across this area, a key component to developing structural thickening and copper enrichment at the Collerina Copper Deposit. The recent auger sampling has confirmed a continuous trend of copper in soil anomalism between the Yathella Prospect to the North and Max's Folly to the south
Ongoing Regional Programs
Further sampling is continuing, testing areas including the Homeville Trend, a trend north of the Collerina Deposit and infill target areas identified from the auger programs so far. Up to 2000 additional samples are expected to be collected during this phase. Robust copper-in-soil anomalous areas will be assessed and prioritised for initial drill testing.
This work continues to illustrate the high value potential targets that are being generated from within Helix's asset portfolio. The new prospect areas being targeted have not been subject to modern exploration.
Rehabilitation
During the 2019 field season Helix has also systematically completed its rehabilitation commitments on its NSW tenements. Clearing rehabilitation liabilities provides flexibility and up-scaling of future drill programs on our flagship Cobar Region assets.
