Drilling focused on extending the Helens Main and Helens South deposits to 150 metres below surface, advancing the understanding of structural controls and confirming the continuity of gold mineralisation.
The 44-hole program drilled 5,319 metres of reverse circulation (RC) and 2,385.1 metres of diamond core and results so far demonstrate the potential for a large open pit development at Helens.
Deeper intersections include: 15.8 metres at 3.77 g/t gold from 266.4 metres; 7 metres at 3 g/t from 144 metres; 5 metres at 3.96 g/t from 90 metres; and 3 metres at 3.41 g/t from 131 metres.
Highlighted, near-surface assays include: 1.1 metres at 135.4 g/t from 46.7 metres; 17 metres at 2.92 g/t from 9 metres; and 10 metres at 2.23 g/t from 10 metres.
The company has also commenced production bore establishment and initial testing of water supply to the Cardinia process plant site.
The geological model developed by Kin indicates that the gold mineralisation is contained within a complex shear zone of up to 40 metres true width.
The zone contains at least three discrete, steeply dipping, north trending structures.
Updated resource estimate due in September
Further geological modelling is underway ahead of an updated mineral resource estimate due for completion by September.
Following the updated resource estimate, Kin will commence metallurgical domaining and test work programs, with a focus on sulphide ore characterisation over the fresh rock portion of the Helens deposit.
Preliminary open pit optimisation works will follow, which will provide new targeting information for phase II extension and infill drilling.
Phase II drilling is expected to begin in the December quarter 2018.
Kin considers water supply to the Cardinia plant site a critical path item for development.
The design for the Cardinia plant at 1.5 million tonnes per annum throughput requires water supply of 50 litres per second, with higher demand of up to 70 l/s during commissioning of the tailings dam.
After identifying several locations that justified development testing, Kin has started production bore establishment and initial testing.
Larger diameter production bores have now been established adjacent to exploration holes where, during exploration, water flow greater than 5 litres per second was encountered from the fractured rock aquifer that underlies the creek system.
