Kalamazoo Resources intersects high-grade gold mineralisation at Lightning target within Castlemaine project
Kalamazoo’s next Victorian drilling program is planned to start late this quarter at the South Muckleford project.
Drilling by Kalamazoo Resources (ASX: KZR) at the Lightning target within its Castlemaine gold project in central Victoria has intersected high-grade mineralisation and increased the project’s gold strike-extent.
The diamond drilling program comprised six holes for a total 1,818m to test a 440m strike-extent of prospective structures interpreted to be an analogue of the high-grade Wattle Gully mine, approximately 5km to the south and within an exploration licence owned by Kalamazoo.
The mine operated from 1934 to 1969 to produce 1.1 million tonnes for 411,000 ounces at 11.1 grams per tonne of gold.
Results from all six diamond holes confirmed the analogue structure consisting of a west-dipping fault zone up to 10m in thickness with abundant quartz veining, alteration and minor visible gold.
Best assays were 0.8m at 11.1g/t gold from 143m; 0.4m at 12.3g/t from 139m; and 0.55m at 10.6g/t from 143m.
Top 10 target
The Lightning prospect was identified in 2019 as one of Kalamazoo’s top 10 priority targets within the Castlemaine project.
The assessment was based on past production and records, historic drilling. results from groundwork, geophysical and geochemical surveys, and recent 3D structural modelling.
Lightning is located 2km south on the same strike-extent as the Mustang prospect, where Kalamazoo announced a series of high-grade results including 1.42m at 261.3g/t gold during a maiden drilling program last year.
Other results from that program included 0.8m at 19.4g/t gold from 319m; and 1.42m at 261.3g/t from 100m, including 0.17m at 1620g/t and 0.8m at 11.1g/t from 143m (at Lightning).
Gold-in-quartz find
Nearby to Lightning and along trend from Mustang, a prospector recently recovered three coarse gold-in-quartz specimens up to 1.5cm long over a relatively small area using a metal detector.
Kalamazoo has made a site inspection of the discovery area and confirmed the location sits within its strike extent.
The company said the Mustang-Lightning mineralised trend is structurally complex and highly-prospective, and warrants further investigation to determine if a high-grade Wattle Gully/Fosterville-style deposit can be identified.
