News: CDT Castle Minerals Says 150Km2 Of Tenure Secured Over Kendenup Graphite Field, page-10

WAITING ON UPDATE OF THIS FOR STARTERS ! Dated 7th October, should be an update this week

Drill Targets Added and Refined at Polelle
Increasing Activity in the Eastern Meekatharra Region




Explorer and project incubator, Castle Minerals Limited (ASX: CDT) (“Castle” or the “Company”) advises
that a specialist geochemical data review and targeting study has enabled it to identify new and refine all
gold and base metal at its Polelle project in the underexplored eastern region of the Meekatharra gold mining
centre of Western Australia (“Project”)(Figs 1 to 2).
The study merged, ‘cleaned-up’ and ‘levelled’ the multi-element data suite from Castle’s own and historical
auger and soil geochemical datasets with the specific aim of better defining orogenic gold and copper-zinc
VHMS-deposit style targets. It then assessed and ranked each anomaly against a number of geological
parameters including expected pathfinder element associations.
Ten high priority targets were highlighted with two adjacent targets classed as Priority 1, both located in an
area not previously prioritised.
The study noted that the association between gold and copper, arsenic, silver, bismuth and molybdenum is
similar to other orogenic gold deposits in the region.
Castle’s geological team is now reviewing the geochemical sampling based targets and their ranking
alongside the structural interpretation developed using recently flown, high-resolution aeromagnetic survey.
A field visit to check and validate the targets will be undertaken in coming days.
Project background
The 150km2 Polelle Project lies 25km south of Meekatharra and 7km southeast of the operating Bluebird
Mine. It comprises one granted exploration licence and eight prospecting licences of which five were
recently granted. The prospecting licences extend Castle’s tenure north by 4km, to adjoin SensOre’s Tea
Well project (refer below).
The Project hosts a mainly obscured and minimally explored greenstone belt between the Mt Magnet Fault
to the west and the Albury Heath Shear to the east. It has been disrupted by a number of secondary splay
structures clearly observed in recently acquired high-resolution aeromagnetics. The Albury Heath shear
hosts the Westgold owned Albury Heath deposit, located immediately adjacent to the east boundary of
Castle’s licence.
Other explorers in the region
At the Side Well project of Great Boulder Resources Limited (ASX: GBR)1
, 15km to the north of Polelle,
the Mulga Bill prospect has become a major focus and is associated with a 5.1km geochemical anomaly.
Whilst gold anomalism at Mulga Bill is of a low-order magnitude, drill testing has returned some very
encouraging intercepts. The Mulga Bill mineralisation is understood to have an intrusive association, as
opposed to the more expected structurally-controlled, orogenic gold association. This has implications for
the Polelle project where the presence of small intrusives was suggested by the recent aeromagnetic data
interpretation.
The Tea Well project of unlisted SensOre P/L2
, which lies between Polelle and Side Well, has also been
the subject of intense evaluation using that Company’s proprietary “AI” or machine-learning approach to
exploration data. It has predicted a mineral system straddling the Polelle anticlinal axis which extends south
and through Castle’s Polelle tenure. SensOre states that there hasn’t been any historical drilling and very
limited geochemical sampling in the vicinity of its ‘coherent cell-cluster mineral system”.
