Kin Mining NL (ASX:KIN) has intersected high-grade gold from its first deep diamond drill hole testing an Induced Polarisation (IP) target along the Eastern Corridor within the 1.4-million-ounce Cardinia Gold Project near Leonora in Western Australia.
The result supports the use of IP to target gold mineralisation along the Eastern Corridor.
Notably, drill‐hole IP22DD001 intersected two zones of sericite‐carbonate with disseminated pyrite mineralisation on and east of the Helen‐Rangoon Fault in an untested area between the Helens and Rangoon deposits.
Standout assays include:
- 2.5 metres at 3.14 g/t gold from 269.5 metres on the fault position coincident with the IP anomaly; and
- 0.6 metres at 30.4 g/t from 104.65 metres in flat east laminated quartz veins.
Meanwhile, drill‐hole IP22DD002 intersected a felsic intrusion with surrounding brecciated mafic rock and minor laminated mineralised quartz veining, including 0.25 metres at 11.64 g/t gold from 38.9 metres.
The remainder of the IP program is awaiting assays and exploration continues to test the prospective Helens‐Rangoon Fault corridor and the Helens East mineralised structure.
First generation of deeper targets
Kin managing director Andrew Munckton said: “This represents a strong start to the 5‐hole diamond drill program, which is designed to test the first generation of deeper targets at Cardinia with the aim of uncovering new, high‐grade discoveries within the exciting Eastern Corridor.
“All five diamond holes were collared to test a series of Induced Polarisation geophysical anomalies.
“The first hole has intersected a zone of sulphide mineralisation in the targeted position and thin, high‐grade laminated veins similar to those intersected further north at Rangoon.
Drill program
As part of its ongoing exploration and growth program at Cardinia, Kin completed a five‐hole diamond drilling program to evaluate a number of IP geophysical anomalies below the Helens, Helens East, Cardinia Hill and Rangoon deposits within the Eastern Corridor.
The purpose of the program was to test the effectiveness of IP geophysics to identify high‐grade gold mineralisation associated with elevated sulphides (mostly pyrite) logged at the Eastern Corridor deposits in previous drilling.
A total of five separate targets were identified and tested with a series of 340 to 400-metre deep diamond holes.
This is the first generation of deeper targets to be tested at Cardinia and represents a significant exploration development for the project.
Forward plan
Kin is planning further detailed petrophysical testing on mineralised samples and unmineralised shale to help distinguish the specific IP response of each material type.
Also, further detailed and potentially deeper IP surveys are required to infill the existing re‐processed Kurrajong survey to provide a consistent 3D picture of sulphide mineralised positions to approximately 300 metres below surface.
Additional targets have been identified on other re‐processed IP sections and these additional targets may also be tested to determine the source of the IP chargeability anomaly at those locations.
Also, Kin is undertaking extensional diamond and RC drilling at the southern end of the Rangoon deposit at depths of up to 200 metres vertical to follow up previous significant intersections.
Following the completion of this work, further closer‐spaced IP surveys may be completed to map additional mineralised positions that may warrant further drill testing
