Kandia Prospect

Kandia Prospect: December 2024 and historical RC drilling within a 6km portion of the total 16km prospective Birimian–granodiorite contact

Background

The Kandia prospect was discovered in 2010 during a programme of reconnaissance field mapping. During this programme a large area of previously unknown artisanal gold workings was discovered that comprise three main groups developed over approximately 600m of strike.

These workings occur within altered Birimian age metasediments and schists, that on a regional scale sit on a major granite/sediment contact that can be traced within Castle’s licences for at least 25km.

A sampling and mapping programme was completed along the regional trend of the mineralisation. This work represented the first known systematic gold exploration conducted in this area and identified nine gold anomalies overs 12km of strike.

An initial 15,000m of RC drilling was undertaken to test these anomalies with significant results being returned from an area 3.5km south of the artisanal workings discovered in 2010.

Gold mineralisation at Kandia is hosted within silicified and weakly pyritic sediments (shales and siltstones) and generally forms a regular west dipping zone within a broader sediment package bounded to the east by granite. Aeromagnetic data shows this area as a magnetic low that is interpreted to represent magnetite destruction associated with a widespread alteration halo associated with the mineralising event.

Since the first drilling in 2011 Castle has completed extensive soil sampling, airborne geophysical surveys and drilled 264 RC holes for 19,541m.
