ASX Announcement 24 February 2021

==> picture [114 x 35] intentionally omitted <==

Up to 4.91g/t Au from rock chip sampling at Polelle Infill soil sampling commenced ahead of planned drilling

  • Rock chip sampling returns up to 4.91g/t Au from a quartz vein breccia associated with a splay off to north of the Albury Heath Shear

  • Grades are consistent with prospector / vendor rock chip sampling and recent Castle auger sampling anomalism in the same area

  • Other anomalous rock chip samples obtained 1.8km further south at Lordy Bore

  • Recent rock chip and auger sampling have confirmed the fertility of the Albury Heath Shear and its northern splay which extend for a combined 12km on the Polelle project

  • Specific drill targets already identified where the splay fault intersects the Albury Heath Shear

  • Additional drill targets expected to be finessed by just commenced infill soil sampling immediately to the north of the splay fault

  • Drilling scheduled to commence as soon as infill soil sampling assays are available and a drill rig secured

  • Polelle is being rapidly advanced from an early-stage exploration proposition, where extensive soil cover has hampered historical exploration, to a position where several targets have been delineated for maiden drill testing

Castle Managing Director, Stephen Stone said “These high-grade rock-chip results of up to 4.9g/t Au from the Polelle project reinforce the recently reported auger sampling which delineated six zones of gold anomalism.”

“An infill soil sampling programme has just commenced to tighten up some of the auger anomalies ahead of drill testing.”

“Polelle ticks a lot of geological boxes with our recent high-resolution magnetic programme confirming that it has an excellent structurally prepared backdrop for the formation of orogenic gold deposits. It lies immediately to the east of the prolific Meekatharra gold mining district but due to a general lack of outcrop and near-surface gold depletion, hasn’t received as much attention as its well-established neighbour.”

Castle Minerals Limited (ASX: CDT) (“Castle” or the “Company”) advises that rock chip sampling of limited outcrop exposures of a brecciated quartz vein has returned up to 4.91g/t Au at the Polelle project in the eastern region of the Meekatharra gold mining district of Western Australia (Figs 1 and 2)(JORC Appendix Table 1).

The veining is closely associated with a structure that splays off to the north of the main Albury Heath shear and which extends for some 7km south onto Castle’s Polelle project. It also marks the contact between mafic volcanics and sedimentary rocks.

The splay structure is one of several interesting geological features identified by Castle’s high-resolution aeromagnetic survey undertaken in late 2020 which could be an important vector into discovering orogenicstyle gold mineralisation (refer ASX release 14 October 2020 and 27 August 2020).

The rock chip samples were collected as part of a field inspection to follow-up anomalous results obtained from the recently completed soil auger sampling programme (refer ASX release 12 January 2021).

Four of the twenty rock chip samples taken along the interpreted splay confirmed the presence of anomalous gold with values of up to 4.91g/t Au.

The splay structure can be followed a further 2.2km south to Lordy Bore where it intersects the Albury Heath Shear at which point further gold anomalism has been identified by previous explorers and Castle.

Overall, the work undertaken by Castle since it acquired the Polelle project in 2020 has confirmed the fertility of the Albury Heath Shear and its northern splay for gold mineralisation. Given these structures have now been shown to extend for a combined 12km on the Polelle licence, there is considerably increased scope for exploration success.

Anomalous gold was also recorded from a rock chip sample collected towards the western boundary of Polelle along a sheared contact between felsic sediments and mafic volcanic units and immediately east of the regionally dominant Mt Magnet shear.

Commencement of infill soil sampling and proposed drilling

The rock chip results are well timed to coincide with the commencement of an infill soil sampling campaign designed to finesse for drilling the recently delineated gold auger geochemical anomalies. Other drill targets around the Lordy Bore area are already effectively drill-ready.

Castle’s maiden drill programme at Polelle is scheduled to commence and be completed in Q2 2021 subject to assay lab turnaround times and drill rig availability.

Geochemical context

Polelle is rapidly being advanced from an early-stage exploration proposition, where extensive soil cover has hampered historical exploration, to a position where several robust targets have been delineated and readied for drill testing.

The recent auger programme has highlighted that the depth of cover in the northern part of the Polelle tenement is a lot less than was previously interpreted. This implies that the dispersion of gold is much less than anticipated, making it harder to vector into and locate discrete zones of mineralisation which, along with the general lack of outcrop, would have exasperated earlier explorers.

This also presents an opportunity for the modern explorer which has at its disposal a much improved range of exploration tools such as satellite imagery, high-resolution aeromagnetics, extremely sensitive assaying techniques and improved understanding of regolith geochemistry and formation processes. For instance, the Castle aeromagnetic survey and updated structural interpretation provide an important geological backdrop to guide geochemical sampling programme design and for the general advance of the project.

About Castle Minerals Limited

Castle Minerals is an Australian Stock Exchange (ASX: CDT) listed and Perth, Western Australia headquartered company with interests in several projects in Western Australia and Ghana that are prospective for gold and other minerals.

==> picture [232 x 358] intentionally omitted <==

==> picture [278 x 357] intentionally omitted <==

At the Wanganui project (E51/1703, 18.4km[2] ), 33km south-west of the active Meekatharra mining centre and 15km south-west of the operating Bluebird gold mine, the opportunity is to test for down-plunge and along strike extensions to the existing Main Lode North and South deposits, as well as for other similar targets. The Main Lode mineralisation, which can be intermittently traced for at least 1km, is one of at least four structurally related mineralised zones.

The Polelle project ( E51/1843, 162.5km2), 25km south of Meekatharra and 7km southeast of the operating Bluebird Mine, hosts a mainly obscured and minimally explored greenstone belt. The belt is comprised of a combination of prospective lithological units and major structural features including the Albury Heath shear which hosts the Albury Heath deposit (Inferred Resource of 528,000t at 2.09g/t Au for 35,479oz Au) immediately adjacent to the east boundary of Castle’s licence. Aeromagnetics have indicated that the southwest trending Albury Heath shear is traceable onto the Polelle project area for some 7.5km.

Castle Minerals Limited – Polelle Rock Chip Sampling Results and Commencement of Soil Sampling – 24 February 2021

The Beasley Creek project lies on the northern flanks of the Rocklea Dome in the southern Pilbara. The strategy is to define structurally controlled gold targets within the various Archean sequences. These lie immediately above and below the 16km east-west striking conglomerate horizons which had been the initial focus of exploration by Castle. The sheared granite - greenstone contact and the “Paulsen Gold Mine” type setting within the gabbro/dolerite units, that intrude the Hardy Sandstone in the northern part of the project area, are of particular interest.

==> picture [436 x 299] intentionally omitted <==

The Success Dome project is a recent application for an exploration licence in the Ashburton structural corridor and is located midway between the Paulsen’s and Ashburton gold deposits. It is prospective for gold and base metals. More locally, Success Dome lies immediately adjacent to the southern margin of the Hamersley Basin and 40km southwest of Castle’s Beasley Creek gold project. Major thrust faults and subparallel shear zones highlighted in the regional magnetic and gravity data, combined with additional detailed geophysics data from previous explorers, brought this available area to Castle’s attention.

In West Africa , Castle has a substantial and contiguous tenure position in Ghana’s Upper West region. Ghana has a long history of gold exploration and mining with several world-class gold mining operations owned by Tier 1 mining companies. Castle’s Ghana licence holdings encompass extensive tracts of highly prospective Birimian geological terrane, the host to many of West Africa’s and Ghana’s multi-million-ounce gold mines. The project is also host to the Kambale graphite project.

Castle also retains a 4% net smelter precious metal royalty over the adjacent Julie West licence which comprises a key component of Azumah’s Wa Gold Project.

Cautionary Statement

All of Castle’s projects in Australia are considered to be of grass roots or of relatively early stage exploration status. There has been insufficient exploration to define a Mineral Resource. No Competent Person has done sufficient work in accordance with JORC Code 2012 to conclusively determine or to estimate in what quantities gold or other minerals are present. It is possible that following further evaluation and/or exploration work that the confidence in the information used to identify areas of interest may be reduced when reported under JORC Code 2012.
