Castle Minerals Limited (ASX: CDT) ('Castle' or the 'Company') advises that it has despatched a field crew to its Woodcutters lithium project to continue its campaign to demonstrate that the Project is a credible lithium exploration camp whose credentials are bolstered by zones of anomalous lithium soils and rock chip samples and it being located in the same structural zone as the Bald Hill lithium mine, 25km north west and now to be owned by Mineral Resources Limited.
It is also in the same region as the Liontown Resources Limited owned Buldania lithium deposit, 25km to the south west ('Woodcutters' or 'Project')(Figs 1 and 2). The recent intense corporate manoeuvring by major resources groups around key projects in the region is indicative of its status and overall prospectivity for lithium. Castle holds two granted exploration licences at Woodcutters which have a combined area of 410km-2 (EL15/1846 and EL15/1847). The north east region of these encompasses some 10km of a more obviously prospective lithium-bearing pegmatite trend. A review commissioned by Castle of historical sampling and multi-element assay data obtained by AngloGold Ashanti (2009-2010), which was exploring specifically for gold (refer Castle ASX release 23 February 2022), revealed several zones of lithium and associated LCT element (rubidium, beryllium, caesium and tin) anomalism.
Castle Managing Director, Stephen Stone commented 'We are very pleased to be sending out a field crew to continue Castle's campaign to demonstrate that Woodcutters is a credible lithium exploration camp whose credentials are bolstered by it being located in the same structural zone as the Bald Hill lithium mine, 25km north west and shortly to be owned and operated by Mineral Resources Limited. It is also in the same region as the Buldania lithium deposit owned by Liontown Resources Limited which is the subject of a takeover offer by Tier-1 lithium producer, Albemarle Australia Limited.
We have rapidly advanced Woodcutters from an opportunistic and conceptual pick-up to a stage where we have confirmed its lithium prospectivity by delineating several zones of consistent lithium anomalism in soils along with supporting anomalous pegmatite rock chips. What is also encouraging is that the relationship of the lithium anomalism to a nearby intrusive centre is consistent with what would be expected with a typically fractionated or zoned lithium bearing pegmatitic system. So, we believe we are on the right track and what we need to do now is to locate more anomalous pegmatites within the higher priority areas of soil anomalism and then extend that search out to other regions. Soil cover makes the task more challenging but overcoming that using modern exploration tools is also the opportunity as it has hampered previous explorers.'
Castle has since undertaken its own soil sampling in the prospective lithium-bearing pegmatite trend and, having combined its data with the historical data, has defined and been able to prioritise five zones of geochemical lithium anomalism. Prioritisation was assigned by specialist geochemist, Sugden Geoscience P/L (refer ASX release 26 April 2023). The distal relationship of the lithium anomalism to a nearby intrusive centre is also consistent with what would be expected with a fractionated or zoned lithium bearing pegmatitic system. A subsequent Castle field follow-up reconnaissance programme identified a pegmatite in close proximity to the peak lithium value soil sample. Sampling of this pegmatite returned a peak anomalous value of 119.9ppm Li. This programme was curtailed due to heavy rain and other logistical constraints at the time. A Castle field crew will now continue the curtailed programme by traversing the remainder of the priority-1 anomalous zone with the aim of identifying and sampling other pegmatites in the area. It will then systematically evaluate the as yet untested priority-2 zones. Only a fraction of Castle's 410km2 licence has been assessed for lithium and, whilst large parts can be discounted on the basis of geology, other areas have yet to receive appropriate attention for lithium mineralization

ABOUT CASTLE MINERALS
Castle Minerals Limited is an Australian Securities Exchange (ASX: CDT) listed and Perth, Western Australia headquartered company with interests in several projects in Ghana and Western Australia that are prospective for Battery Metals (graphite and lithium), base metals (zinc, lead and copper) and gold. In Ghana, West Africa, Castle's 2,686km2 tenure position in the country's Upper West region encompasses large tracts of highly prospective Birimian geological terrane, the host to many of West Africa's and Ghana's multi-million-ounce gold mines. It has delineated several advanced gold exploration targets including at Castle Minerals Limited - Pegmatite Evaluation Commences at Woodcutters Lithium Project. Page 5 of 6 Kpali, Bundi and Kandia. Castle also retains a 4% net smelter precious metal royalty over the Julie West licence, a key component of Azumah Resources Limited's Wa Gold Project, Upper West region, Ghana. The emerging flagship Kambale Graphite Project is also located in the same region. In Western Australia, The Earaheedy Basin project comprises the Withnell and Terra Rossa sub-projects. The Withnell licence is strategically located adjacent to the evolving World-Class ChinookMagazine zinc-lead project of Rumble Resources Ltd (ASX: RTR) and north of the Strickland Metals Limited (ASX: STK) Iroquois prospect. The Terra Rossa licences have additional prospectivity for copper. The Beasley Creek project is prospective for gold and lithium and lies on the northern flanks of the Rocklea Dome in the southern Pilbara. The Success Dome project lies in the Ashburton structural corridor midway between the Paulsen's and Ashburton gold deposits and is prospective for gold and base metals. The Polelle project, 7km southeast of the operating Bluebird gold mine near Meekatharra, hosts a mainly obscured and minimally explored greenstone belt prospective for gold and possibly base metals whilst the Wanganui project is prospective for down-plunge high-grade gold shoots. The Wilgee Springs project, along strike from and within the same metamorphic belt as the world-class Greenbushes lithium mine 25km to the south, is prospective for spodumene bearing pegmatites as is the Woodcutters project, 25km south east of the Bald Hill lithium mine and 25km north west of the Buldania lithium deposit. The Woomba Well project is also prospective for lithium bearing pegmatites. The Great Southern Graphite project comprises granted licences encompassing the historical Kendenup graphite workings and the adjacent Martagallup graphite occurrences.
