Kin Mining NL (ASX:KIN) has received near-surface, high-grade results in 1-metre split samples from Lewis East and Lewis West prospects at the Cardinia Gold Project (CGP) near Leonora, Western Australia.
The samples were generated from aircore (AC) drilling completed in December 2019 and confirmed near-surface, high-grade zones of gold mineralisation at Lewis East.
- 11 metres at 3.85 g/t gold from 24 metres, including 8 metres at 5 g/t from 24 metres
- 6 metres at 3.63 g/t from 9 metres, including 2 metres at 9.27 g/t from 10 metres
- 19 metres at 1.04 g/t from 14 metres, including 5 metres at 2.28 g/t from 26 metres
The Lewis East results add to those released on March 11, 2020, and continue to confirm the presence of several NE-dipping lodes of high-grade gold mineralisation, within wider haloes of lower grade.
“Higher grade core”
Kin Mining managing director Andrew Munckton said: “The Lewis East mineralisation based on the 4-metre composite assays was interpreted to be broad zones of medium-grade material with occasional higher-grade zones generally in a northeast dipping orientation.
“The 1-metre split sampling has confirmed that the broad medium grade intersections generally contain a narrower, higher grade core of mineralisation displaying vein style pyrite mineralisation surrounded by lower grade disseminated sulphides and alteration.
Results from the 1-metre sampling have helped the company’s geological teams define controls on the mineralisation more clearly.

Munckton said: "The Lewis East mineralisation occurs directly along strike of the two northeast dipping Lewis lodes, which have undergone extensive historical RC and diamond drilling.”
“The Lewis Fault system is intimately associated with mineralisation at the Lewis, Lewis East, Nevertire, Black Chief and Comedy King deposits.
“These deposits are spread over an area covering approximately 4 kilometres by 2 kilometres and represent a cluster of deposits displaying both high-grade vein and lode style mineralisation and lower grade alteration halo mineralisation, all with a common geological control.”
The Lewis West results, whilst not producing grades worthy of significant follow-up, namely 1 metre at 3.24 g/t from 10 metres, have highlighted the important role the NE-trending faults play in focusing the flow of mineralising fluids.
These results highlight a clear zone of anomalism located along a structure related to the Lewis Fault system, which suggests the faults play an important role in focusing fluid flow before gold is deposited in favourable settings.
No further drilling at Lewis West is planned.
Munckton said: “Further RC drilling at Lewis East is planned to test the depth and strike extent of the Lewis East lodes and the potential continuity with the Lewis mineralisation.
“These veins appear to be initiated from northeast-trending faults associated with the rapidly expanding Lewis Fault system.”
The RC rig is drilling at Cardinia Hill and will move to the prospect in mid-April.
