Excellent Gold Intercepts From Drilling at Kandia Prospect
•
Drilling at Kandia Gold Prospect, in Upper West Region of Ghana, delivers strong
gold intercepts from shallow depth.
•
All four RC holes at “4,000-Zone” intersected mineralisation including:
•
7m at 3.36g/t gold from 149m within 24m at 1.78g/t Au from 139m (24KARC002).
•
5m at 3.49g/t Au from 82m within 11m at 2.26g/t Au from 79m (24KARC004).
•
Programme has confirmed continuity and depth extension of mineralisation with
grade, mineralised width and dip appearing to increase with depth.
•
The opportunity at Kandia is to delineate multiple, near-surface open-pitable
deposits along the 16km prospective contact.
•
Next stage is extensional drilling at “4,000-Zone” and focused drilling at several
other areas of historical wide-spaced shallow drilling i.e. “8,000-Zone” where
artisanal miners are also active.
•
Results from a follow-on eight-hole RC drilling programme at Castle’s other flagship
gold prospect, Kpali, are expected to be reported in early-February 2025.
______________________________________________________
Castle Executive Chairman, Stephen Stone, commented:
“This four-hole, 582m drilling programme at the Kandia prospect’s “4,000-Zone” has
delivered a lot of “bang for our precious buck” providing considerable encouragement
that we can materially increase tonnes and grade here.
Now that we are getting our eye in, this should also apply at the several other areas of
mineralisation that have been identified by historical shallow wide-spaced drilling along
the 16km prospective Kandia contact zone.
All four holes intersected mineralisation including 7m at 3.36g/t gold from 149m within
24m at 1.78g/t Au from 139m (24KARC002) and 5m at 3.49g/t Au from 82m within 11m at
2.26g/t Au from 79m (24KARC004).
Many of the major discoveries in the Upper West Region, Ghana and West Africa
generally commence life as what at first appear to be just shallow zones of low-grade
anomalism. Persistence and a careful attention to all available data can often see these
grow into substantial discoveries extending to great depth.
We are looking forward to undertaking more drilling at the 4,000-Zone, the 8,000 Zone
4km to the north, at several areas in between these and then further north where the
prospective geology trends onto the 2.5Moz Black Volta Gold Project tenure.
Results from the follow-on eight-hole RC programme at the Kpali gold prospect will be
reported in early February 2025.”

Castle Minerals Limited (“Castle” and/or the “Company”) advises that a 4-hole, 582m RC drilling
campaign at its Kandia gold prospect within its broader 2,686km2 Wa Gold Project in Ghana’s Upper
West Region, has successfully confirmed continuity of mineralisation and extended this to greater depth.
All four holes intersected mineralisation with two returning some of the best intercepts in the Kandia
prospect area to date including 7m at 3.36g/t Au from 149m within 24m at 1.78g/t Au from 139m
(24KARC002) and 5m at 3.49g/t Au from 82m within 11m at 2.36g/t Au from 79m (24KARC004).
Grade and width of mineralisation appear to be increasing with depth
(24KARC002) along with an increase in dip and the likelihood of a northtrending plunge. Combined, these provide for more focused targeting that
was not available in previous rounds of drilling.
Drilling was confined to the “4,000-Zone” where mineralisation has
previously been confirmed over a strike of ~850m. This zone is one of
several prospects that have been outlined by a series of soil sampling,
RAB and RC drilling campaigns. These were conducted over an area of
initial focus extending for some 6km along the sheared contact between
Birimian metasediments (mineralised) and a regional-scale granodiorite
intrusion (unmineralised).
This prospective contact has been recognised for over 16km on Castle’s
tenure providing ample opportunity for more mineralisation to be outlined
though systematic exploration.
Sporadic artisanal (galamsay) mining occurs within and around the
4,000-Zone with new workings appearing more recently along the
prospective contact i.e. the “8,000-Zone”, providing an additional
confirmation of the presence of mineralisation.

Castle Minerals Limited: Kandia Gold Prospect RC Drilling Results.
Castle’s immediate objective at Kandia is to delineate a large tonnage of near-surface, open-pitable
mineralisation across several zones. This would be in addition to mineralisation delineated at other
prospects within the broader Wa Gold Project where Castle’s objective is delineate an initial combined
1.0Moz of gold resources across a cluster of these prospects.
A combined maiden 2012 JORC Mineral Resource of 92,700oz grading 1.0g/t Au (comprising 1.772M
tonnes at 1.0g/t Au for 57,700oz Indicated and 1.006M tonnes at 1.1g/t Au for 34,900oz Inferred) was
estimated for the 4,000-Zone and the 8,000-Zone, 4km to the north-east (refer ASX release 2 July 2014
titled ‘Maiden Resource Estimate for the Kpali Gold Prospect’) and has provided a focus for the recent
work.
Gold in West Africa
West Africa is one of the world’s premier regions to be exploring for gold, delivering an enviable fifteen
discoveries of over two million ounces each since 2012 and Ghana’s northern region is now considered
one of the best areas to find more of these.
Notable projects include the newly commissioned 5.1Moz Namdini gold deposit discovered by Cardinal
Resources Limited prior to its takeover in 2020 and the Azumah Resources Limited owned 2.8Moz Black
Volta Gold Project (“BVGP”) which is earmarked for development in 2025. Namdini lies on the same
Bole-Bolgatanga Birimian greenstone belt as Kandia and the BVGP’s Julie deposit is immediately along
strike of the Kandia mineralised trend.

The mineralisation at Kandia lies along the contact
between a granitoid body and a Birimian
metasedimentary unit. Shearing is evident along the
contact and most of the gold mineralisation appears
to be associated with this shearing event. The quartz
veining is mostly associated with metasedimentary
rocks and occasional metavolcanic units. Veins are
usually concordant with foliation and are
characterised by dustings of fine sulphides.
