Cazaly Resources Limited announced a Maiden Ore Resource for its 100% owned Bommie Porphyry Copper deposit at the Halls Creek Project in the East Kimberley, northern Western Australia. Cazaly's recent 2022 RC drilling campaign at the Bommie prospect has culminated in a maiden Mineral Resource Estimate (MRE). The total MRE envelope covers 950m of strike N-S with widths ranging from 300m to 600m and extends from surface in places to 340m below surface.

The resource was classified as indicated where drilling was of sufficient density in the central western portion of the deposit, and encompasses 360m of strike N-S, up to 230m width and extends from surface to a depth of 150m. The company engaged Hyland Geological and Mining Consultants (HGMC) to complete the MRE for the Bommie Porphyry Copper Prospect. The Bommie MRE1 is reported in accordance with the JORC Code 2012.

Collar co-ordinates and assay information from this latest round of drilling were reported in ASX announcement dated 14 October 2022. Mineralisation is interpreted to be moderately east dipping, with higher grades noted in western portion of the deposit. The Bommie Copper resource remains open in all directions and there is opportunity for growth of the mineral resource especially to the north and west, and at depth in places.

The project is situated 25km southwest of Halls Creek and covers part of the Halls Creek Mobile Zone which is highly prospective for a range of commodities including copper, gold, and nickel. The project includes the Mount Angelo North Copper-Zinc deposit, an extensive zone of near surface oxidised Cu-Zn mineralisation overlying massive Cu-Zn sulphide mineralisation. The Mount Angelo North mineral resource estimate2 is reported in accordance with the JORC Code 2012 as 1.72Mt @ 1.4% Cu, 1.4% Zn, 12.3ppm Ag (using 0.4% Cu lower cut) for 23kt Cu, 25kt Zn, 680koz Ag.

The mineral resource includes the following anomalous intercepts: 64m @ 2.7% Cu (1.1% Zn), 62m @ 2.4% Cu (2.8% Zn), 37m @ 2.6% Cu (6.1% Zn). Geology and geological interpretation: The Bommie prospect is interpreted to represent a porphyry copper occurrence, the final mineralised phase of the intrusive Mount Angelo microgranite. The Mount Angelo microgranite has intruded the Koongie Park volcanics where it is bound by the Angelo Fault and a major splay from it.

It is found along strike from the Mount Angelo VMS occurrence. Copper mineralisation at the Bommie prospect occurs as disseminated sulphides primarily chalcopyrite and extends from surface where the sulphides are oxidised and copper is evidenced by malachite (a copper carbonate hydroxide mineral). The majority of the geologically interpreted Bommie mineralised occurrence has an approximate 950m strike length.

The mineralisation interpreted width ranges from approximately 300 m to 600m.Mineralization in the majority of the deposit area extends and has been modelled to a depth of approximately 340 m below topographic surface. All available RC and Diamond drilling data was used to build the mineralisation model and for guiding Mineral Resource estimation. Recent verification RC drilling carried out by Cazaly has also enabled some of the estimated resources to be assigned a higher level of resource estimation confidence and therefore higher level of resource reporting classification.

Sampling and sub-sampling techniques: RC samples were collected at 2 metre composited intervals by rig mounted cone splitter to make up a total weight of approximately 3kg per sample submitted. Some validated drill holes were also sampled at between 1 and 3 metre intervals. The most recent Cazaly RC samples were sent to an accredited laboratory in Perth for sorting, crushing, pulverization and analysis by fire assay (Au) and four acid digest (multielement suite) methods.

Samples from all RC and DD drilling were considered representative and appropriate for the material sampled. Drilling techniques: Two drilling techniques were used reverse circulation drilling completed with a 139mm face sampling hammer, and diamond drilling producing HQ and NQ sized core. The majority of the samples were collected by reverse circulation techniques.

All drilling by Cazaly was undertaken using reverse circulation drill rigs. Criteria for resource classification: The drill holes are spaced on a nominal 100m north-south, east-west grid with some drill spacing variability ranging from 50m to 150m. The majority of holes were drilled to the west.

The data spacing and distribution is suitable to establish geological and grade continuity. Classification of the resource has been assigned by the Competent Person and includes a series of project specific `modifying factors' appropriate for the Resource estimation. A small amount of Indicated Resources is estimated with the majority of mineralization being classified as Inferred.

The classification was considered appropriate on the basis of drill hole spacing, sample interval, geological interpretation, and representativeness of all available assay data. The Competent Person considers the mineral resource to be a robust and reliable global estimate of the contained Copper and related mineralization. The estimation has been constrained within defined mineralisation wireframes.
