Noombenberry Project, WA
The Noombenberry Project is located 300 kilometres east of Perth in Western Australia, and is prospective for kaolinite and halloysite.
Exploration programs are underway.
Maiden air-core drilling campaign has been completed on a nominal 200m x 200m grid patten for a total of 197 holes for 4,430 meters
Drilling intersected bright white kaolin up to 50m thick across the 18km2 area drill tested which remains open to the north, south, east, and west.
Noombenberry Halloysite project covers 54km² near Merredin, less than 300km from Perth, with Fremantle Port easily accessible via the Great Eastern Highway.
All services required for a low-cost mining operation are in close proximity.
Mineralisation is predominantly outcropping and flat lying over the project area.
The assay results of raw samples displayed grades of Al203 of up to 25%.
Identification of Halloysite located in multi-site surface sampling
Testing conducted by UK based First Test Minerals, specialists in kaolin for 30 years
Good halloysite occurrence at multiple sample sites – forming as ‘plates’ and ‘tubes’
Halloysite at up to 15% by weight at sample site #4 noted (45 – 180um)
Native title period currently in advertising period, grant expected in 1st quarter
Historical drilling located in project area, data to be reviewed and assessed for future drilling program
WA Halloysite project Acquisition
In 2019, Latin acquired Electric Metals Pty Ltd, (Electric Metals), Halloysite Project, located near Merredin, WA less than 300km from Port of Fremantle and its Big Grey Silver-Lead Project, located in WA’s Paterson region.
Soft Rock Halloysite Project
The flagship project is the 54 km2 Soft Rock Halloysite project (E77/2622) that is spread across two contiguous tenements.
Scientists from the Geological Society of WA identified the deposit in 1999, however it remained undiscovered by commercial exploration companies until being located this year by Electric’s project generation team.
Sample GSWA 94490 contained nearly 50% tubular Halloysite, an exceptionally high grade and unique form of Halloysite.
SEM studies indicated medium-grained kaolinite in sample GSWA 94489, with well- developed hexagonal stacked platelets.
GSWA sampling at the project also returned ISO brightness results of 71% to 79% from raw samples, with higher results easily achievable by separating the kaolinite from other minerals such as quartz.
The project is located near Merredin, less than 300km from Perth, with port easily accessible via the Great Eastern Highway. All services required for a low-cost mining operation are in close proximity.
Big Grey Silver-Lead Project:
138km2 granted exploration tenement in WA’s Paterson region.
The tenement is entirely underlain by the same magnetic anomaly that hosts Rumble Resource’s Braeside-Barramine high grade lead-silver-barium projects where drill assays up to 48% lead, 131g/t silver and 3.8% barium have been recorded by Rumble.
Exploration by Rumble to the North on the same magnetic trend has outlined a large mineralised vein array system over 60km in strike and 8km in width.
Rumble’s interpretation of a porphyry related geological model has identified a preserved, near complete porphyry to epithermal system, which is a rare discovery for Archaean age rocks.
The new development has upgraded Rumble’s Braeside Project to a regional scale base metal system located in the Paterson region, which is known for large scale deposits.
Prices for Halloysite and industrial minerals.
Pure Halloysite sells for up to US$3,000/t.
Kaolin/Halloysite hybrid AU$500 – AU$1,000/t.
Pure Kaolin for AU$300/t.
Halloysite presents a low mining risk, minimal disturbance, bulk commodity with attractive profit margins.
Strong investor interest in Halloysite as a globally scarce commodity with strong demand drivers.
Main markets for Halloysite are the high end ceramics and the petroleum industry as a catalyst for fluid catalytic cracking (FCC).
New and emerging markets developing for Halloysite such as an input in producing high purity alumina (HPA), Halloysite nanotube technologies, and cancer therapeutics.

Positive Kaolinite & Halloysite results returned from UK test lab
Latin announced in January 2020, the positive results from a first pass sampling program conducted at the Noombenberry project.
The results prepared by an independent expert being First Test Minerals a United Kingdom based kaolin and halloysite specialist.
A series of four kaolinitic samples collected from the surface in the Noombenberry clay project in Western Australia (ASX: 20 November 2019) submitted to First Test Minerals in the UK for determination of kaolin/halloysite clay content, quality and sales potential. Testing was conducted via Scanning Electron Microscopy (SEM) to identify halloysite occurrence in samples.
A total of 13 samples were taken from the Noombenberry project site which exhibits outcropping across an area of approximately 50km².
