Ann: Update on field exploration near Broken Hill NSW, page-9

The IP survey defined a chargeability zone from 150 to 250(+?) metres deep. The highest chargeability zone is at 150 metres depth, this will be tested by NK1 (EHRC001) and NK3 (EHRC002). The deeper chargeability zones at 250+ metres depth will be tested by NK2 (EHRC004) and NK4 (EHRC003). Chargeability zones can be indicative of a sulphide source.

From last week Ann:
'The strongest source is centred around 558325E 6433600N with its core at a depth of around 160 m. It is oriented roughly EW with a strike length of around 500 m, a width of around 100 m and the 3D inversion model indicates it has significant depth extent. The IP survey at Eaglehawk has delineated two chargeability anomalies which have been resolved into well-defined chargeable zones by inversion modelling....
.... The initial drill testing is proposed for 1,200 m with 4 drill holes designed to intersect the main zone at -150 m and -250 m below the surface. Figures 3 illustrates the proposed initial drill holes NK1 and NK3 and how it willtest the high chargeability zone. Proposed drill holes NK2 and 4 are designed to test the target at -250 m below the surface. The IP anomaly was modelled in 3D (Figure 4) to refine drill holes EHRC001 to EHRC004..... '



Interestingly, the hole that has been extended to 270 metres -NK3 (EHRC002)- was designed to test the high chargeability zone of roughly 150 metres depth. Maybe the target was deeper than they had anticipated? Maybe the target zone is larger than anticipated?

Today's Ann:

'As of Sunday, 21 March 2021 one drill hole has been completed, EHRC001 at 253 m. A second drill hole EHRC002 was at 211 m and it will be extended to 270 m from the original planned depth of 250 m. The third drill hole is EHRC003 with a targeted depth of 350 m and will be drilledbeneath EHRC002 that is currently underway.

As to your question about drilling the EHRC002 deeper to save money they are drilling at 60 degrees dip, they can't drill a hole deeper and expect to hit the same target further down the hole.

Anyway I'm just a layman so take it with a grain of salt..
