THE DRILL SERGEANT: Blackham Resources (ASX: BLK) announced drilling at the company’s high-grade free milling Golden Age orebody has extended mineralisation beyond current mining areas.
Blackham Resources drilled 19 surface RC holes and 30 underground diamond holes throughout March to May focused on extensions to the Golden Age deposit.
Drilling of the Golden Age lower extensions encountered mineralisation 150 to 300 metres below the current mining levels:
6.9 metres at 15.5 grams per tonne gold; and
2m at 11.8 g/t gold.
Surface drilling at Golden Age North intersected high-grade shallower mineralisation amenable to both open pit and underground mining of:
2m at 28.3g/t gold from 75m 57;
6m at 7.97g/t gold from 106m and 1m at 6.14g/t gold 54;
8m at 5.82 g/t gold from 87m 47;
7m at 1.52 g/t gold from 12m and 14m at 1.26g/t gold 28;
7m at 2.97 g/t gold from 80m 21; and
4m at 4.24 g/t gold from 94m 17.
Infill drilling extended remnant mineralisation currently being mined, including:
2.1m at 43.6g/t gold and 1.1m at 7.28g/t Au 97;
6.5m at 8.88g/t gold and 2.8m at 5.81g/t Au 74;
5.1m at 4.15g/t gold 21;
1.1m at 17.4g/t gold 19; and
2.1m at 7.87g/t gold 16.
Blackham Resources indicated the Golden Age drilling program is to be extended further with a view to both lengthening the mine plan and increasing the mining rate at Golden Age.
The free milling resources and reserves are currently being updated to incorporate recent Wiluna and Golden Age drilling results.
“Blackham is pleased to announce new drill results from our high-grade Golden Age orebody which have identified significant extensions to mineralisation within 200 metres of existing underground development,” Blackham Resources executive chairman Milan Jerkovic said in the company’s announcement to the Australian Securities Exchange.
“Based on the highly encouraging intercepts, planning has commenced for further drilling to better define the mineralised extensions and to support early underground development to provide additional high-grade ore to feed the Wiluna gold plant, which last quarter produced 20,631 ounces at AISC $1,092 per ounce.”
