Kin Mining NL (ASX:KIN) is paving the way for resource updates at the Lewis and Helens prospects within the Cardinia Gold Project (CGP) in WA after receiving encouraging results from recent drilling.
Updated resource estimates for the prospects are expected in the June quarter.
Lewis and Helens are expected to form part of the first two open pit developments proposed at the CGP, which is near Leonora.

At Lewis, recent reverse circulation (RC) and diamond drilling has confirmed the geological model.
High-grade volcanogenic massive sulphide (VMS) style intersections were returned at depth below orogenic gold-rich sulphide mineralisation and near-surface, supergene/epithermal mineralisation.
Lewis results
There were eight diamond holes drilled for 1,242 metres and a further 1,472 metres of RC drilling at Lewis with results from one of the diamond holes and all RC holes still to come.
Best results from the seven diamond holes are:
- 4.9 metres at 18.8 g/t gold from 201.3 metres; - 2.2 metres at 5.0 g/t from 18.1 metres; - 11.0 metres at 1.94 g/t from 103.0 metres, including 2.8 metres at 5.9 g/t from 103.0 metres; and - 2.7 metres at 3.2 g/t from 123.0 metres.

Results support Kin’s objective of the Lewis deposit providing a large, baseload feed source for the CGP supplemented by higher-grade satellite deposits like Helens and Mertondale 5.

At Helens, drilling confirmed consistent lode-style gold mineralisation associated with sulphide-rich shear zones, alteration and veining.
7.1 metres at 4.7 g/t
There were 14 diamond holes drilled for 1,085 metres while RC drilling totalled 837 metres.
Assays have been received from nine of the diamond holes with best results of:
- 7.1 metres at 4.7 g/t from 45.3 metres; - 7.8 metres at 3.4 g/t from 13.2 metres and 3.5 metres at 2.7 g/t from 60.5 metres; and - 8.1 metres at 1.1 g/t from 20.6 metres.

The Helens resource definition drilling has shown that the recently updated geology model is robust with all new RC and diamond holes intersecting lode-style mineralisation at the predicted position in the resource models.
Potential underground scope
This set of results indicates potential scope for lode-style underground mining following open-pit mining in the initial phase of development.
The ongoing drilling program will now move to the Mertondale 5 and Bruno prospects.
