High-grade assay results from infill reverse circulation drilling at the Mount Flora project near Leonora in Western Australia have defined zones of primary gold mineralisation for Kin Mining (ASX: KIN).
Results from the remaining 17 holes of a 25-hole program for 3,169 metres completed in November outlined deeper primary mineralisation below previous aircore drilling and helped refine the company’s understanding of the project’s structural model.
Drilling was focused on the Eastern Zone target and completed mostly on 80m and 40m-spaced sections spanning approximately 600m of strike length.
An additional two holes were completed beneath anomalous aircore drilling results at the Northern Zone target.
One of the holes returned a broad intercept of 18m at 1.57 grams per tonne gold from 119m, including 4m at 2.23g/t from 119m and 2m at 5.65g/t from 135m, within an extensive zone of sulphide mineralisation and pervasive scheelite veining.
Also reported was an assay of 22m at 0.86g/t gold from 102m including 3m at 2.4g/t from 102m and 2m at 2.35g/t from 122m.
Several holes at the Eastern target intersected relatively narrow zones of high-grade mineralisation such as 2m at 4.06g/t gold from 31m, 2m at 9.67g/t gold from 78m and 2m at 4.34g/t gold from 97m along strike from results from initial aircore and diamond drilling.
At the Northern target, narrow zones of high-grade mineralisation such as 6m at 2g/t gold from 45m and 1m at 25.5g/t gold from 86m provided an initial assessment of the potential below the target.
Kin said confirmation of a high-grade primary gold system beneath aircore drilling at both targets is a “significant development” and provides further confidence in the potential of the emerging Mount Flora discovery.
Style of mineralisation
The zones of deeper high-grade mineralisation at Mount Flora were reported to display a distinctive style of alteration, with quartz-carbonate-pyrite-scheelite veining present in a silica-biotite altered basalt.
The mineralisation is believed to be rich in tungsten with elevated tellurium and sulphur, which are pathfinder elements being used to map the alteration system.
Overall, the combination of soil geochemistry, aircore and diamond drilling, and primary mineralisation returned from reverse circulation drilling confirm the discovery of several zones of strong gold mineralisation associated with a regional structure, coupled with a distinctive alteration signature.
Mount Flora remains one of several satellite targets being explored by Kin’s geological team alongside the company’s flagship 1.28-million-ounce Cardinia gold project.
Earlier this month, the junior explorer commenced drilling at the project’s Pegasus prospect as part of an effort to grow Cardinia’s resources.
